A multi-mode drill can include a transmission to transfer torque from an output member of a motor to an output spindle. A transmission housing encloses the transmission in an interior cavity formed by a gear case shell and a cover plate. The cover plate can be coupled to the outer shell via screws. A static shift rod can be supported at one end by the cover plate. A shift bracket can be mounted on the shift rod and biased to a mode position by a biasing member exerting a force between the shift bracket and the cover plate. A shift pin can be supported adjacent one end by the cover plate and biased to a mode position by a biasing member exerting a force between the shift pin and the cover plate. A spindle biasing member can bias the output spindle against the cover plate. The shift pin can actuate an electronic switch. A motor housing can be coupled to the transmission housing with fasteners so that the cover fasteners are not accessible.
The present disclosure relates to a drill, and more particularly to a multi-mode drill with a gear case cover plate.
The statements in this section merely provide background information related to the present disclosure and may net constitute prior art.
Multi-speed drills can include a transmission for transferring torque between a driven input member and an output spindle. The transmission can be a constant mesh parallel axis transmission including a low speed gear and a high speed gear. These transmissions can selectively couple the input member to the output through the low speed gear or the high speed gear. The transmission can include biasing members. Additionally, the transmission can include various components that ultimately must be supported at the interior end of the transmission.
Multi-speed drills can also include shifting mechanisms for shifting between the various modes of operation. For example, a shifting mechanism can operate to shift between the low speed gear and a high speed gear of a transmission. Like transmissions, such shifting mechanisms can include biasing members. Additionally, the shifting mechanisms can include various components that ultimately must be supported at the interior end of the transmission.

FIG. 26 is a partial cross-section view of various shift locking member components.
With initial reference to FIG. 1, an exemplary hammer-drill constructed in accordance with the present teachings is shown and generally identified at reference numeral 10. The hammer-drill 10 can include a housing 12 having a handle 13. The housing 12 generally comprising a rearward housing 14, a forward housing 16 and a handle housing 18. These housing portions 14, 16, and 13 can be separate components or combined in various manners. For example, the handle housing 18 can be combed as part of a single integral component forming at least some portion of the rearward housing 14.
In general, the rearward housing 14 covers a motor 20 (FIG. 18) a n d the forward housing 16 covers a transmission 22 (FIG. 11). A mode collar 26 is rotatably disposed around the forward housing 16 and an end cap 28 is arranged adjacent the mode collar 26. As will be described in greater detail herein, the mode collar 26 is selectively rotatable between a plurality of positions about an axis 30 that substantially corresponds to the axis of a floating rotary-reciprocatory output spindle 40. The mode collar 26 is disposed around the output spindle 40 and may be concentrically or eccentrically mounted around the output spindle 40. Each rotary position of the mode collar 26 corresponds to a mode of operation. An indicator 32 is disposed on the forward housing 16 for aligning with a selected mode identified by indicia 34 provided on the mode collar 26. A trigger 36 for activating the motor 20 can be disposed on the housing 12 for example on the handle 13. The hammer-drill 10 according to this disclosure is an electric system having a battery (not shown) removably coupled to a base 38 of the handle housing 18. It is appreciated, however, that the hammer-drill 10 can be powered with other energy sources, such as AC power, pneumatically based power supplies and/or combustion based power supplies, for example.
The output spindle 40 can be a floating rotary-reciprocatory output spindle journaled in the housing 12. The output spindle 40 is driven by the motor 20 (FIG. 20) through the transmission 22 (FIG. 11). The output spindle 40 extends forwardly beyond the front of the forward housing 16. A chuck (not shown) can be mounted on the output spindle 40 for retaining a drill bit (or other suitable implement) therein.
Turning now to FIGS. 2-9, the mode collar 26 will be described in greater detail. The mode collar 26 generally defines a cylindrical body 42 having an outboard surface 44 and an inboard surface 46. The outboard surface 44 defines the indicia 34 thereon. The indicia 34 correspond to a plurality of modes of operation. In the example shown (see FIG. 2), the indicia 34 includes the numerals "1", "2", "3", and drill and "hammer" icons. Prior to discussing the specific operation of the hammer-drill 10, a brief description of each of these exemplary modes is warranted. The mode "1" generally identified at reference 50 corresponds to an electronic low speed drilling mode. The mode "2" generally identified at reference 52 corresponds to a mechanical low speed mode. The mode "3" generally identified at reference 54 corresponds to a mechanical high speed mode. The "hammer-drill" mode generally identified at reference 56 corresponds to a hammer-drill mode. As will become appreciated, these modes are exemplary and may additionally or alternatively comprise other modes of operation. The outboard surface 44 of the mode collar 26 can define ribs 60 for facilitating a gripping action.
The inboard surface 46 of the mode collar 26 can define a plurality of pockets therearound. In the example shown, four pockets 62, 64, 66, and 68, respectively (FIG. 4), are defined around the inboard surface 46 of the mode collar 26. A locating spring 70 (FIGS. 6-9) partially nests into one of the plurality of pockets 62, 64, 66, and 68 at each of the respective modes. As a result, the mode collar 26 can positively locate at each of the respective modes and provide feedback to a user that a desired mode has been properly selected. A cam surface 72 extends generally circumferentially around the inboard surface 46 of the mode collar 26. The cam surface 72 defines a mechanical shift pin valley 74, a mechanical shift pin ramp 76, a mechanical shift pin plateau 78, an electronic shift pin valley 80, an electronic shift pin ramp 82, an electronic shift pin plateau 84, and a hammer cam drive rib 86.
With specific reference now to FIGS. 3 and 6-9, the mode collar 26 communicates with a mechanical speed shift pin 90 and an electronic speed shift pin 92. More specifically, a distal tip 94 (FIG. 3) of the mechanical speed shift pin 90 and a distal tip 96 of the electronic speed shift pin 92, respectively, each ride across the cam surface 72 of the mode collar 26 upon rotation of the mode collar 26 about the axis 30 (FIG. 1) by the user. FIG. 6 illustrates the cam surface 72 of the mode collar 26 in mode "1". In mode "1", the distal tip 96 of the electronic speed shift pin 92 locates at the electronic shift pin plateau 84. Concurrently, the distal tip 94 of the mechanical speed shift pin 90 locates at the mechanical shift pin plateau 78.
FIG. 7 illustrates the cam surface 72 of the mode collar 26 in mode "2". In mode "2", the distal tip 96 of the electronic speed shift pin 92 locates on the electronic shift pin valley 80, while the distal tip 94 of the mechanical speed shift pin 90 remains on the mechanical shift pin plateau 78. FIG. 7 illustrates the dial 72 of the mode collar 26 in mode "3". In mode "3", the distal tip 96 of the electronic speed shift pin 92 locates on the electronic shift pin valley 80, while the distal tip 94 of the mechanical speed shift pin 90 locates on the mechanical shift pin valley 74. In the "hammer-drill" mode, the distal tip 96 of the electronic speed shift pin 92 locates on the electronic shift pin valley 80, while the distal tip 94 of the mechanical speed shift pin 90 locates on the mechanical shift pin valley 74. Of note, the distal tips 96 and 94 of the electronic speed shift pin 92 and the mechanical speed shift pin 90, respectively, remain on the same surfaces (i.e., without elevation change) between the mode "3" and the "hammer-drill" mode.
As can be appreciated, the respective ramps 76 and 82 facilitate transition between the respective valleys 74 and 80 and plateaus 78 and 84. As will become more fully appreciated from the following discussion, movement of the distal tip 96 of the electronic speed shift pin 92 between the electronic shift pin valley 80 and plateau 84 influences axial translation of the electronic speed shift pin 92. Likewise, movement of the distal tip 94 of the mechanical speed shift pin 90 between the mechanical shift pin valley 74 and plateau 78 influences axial translation of the mechanical speed shift pin 90.
Turning now to FIGS. 10, 13-17, the hammer-drill 10 will be further described. The hammer-drill 10 includes a pair of cooperating hammer members 100 and 102. The hammer members 100 and 102 can generally be located adjacent to and within the circumference of the mode collar 26. By providing the cooperating hammer members 100, 102 in this location a particularly compact transmission and hammer mechanism can be provided. As described hereinafter, hammer member 100 is fixed to the housing so that it is non-rotatable or non-rotating. On the other hand, hammer member 102 is fixed to the output spindle 40, e.g., splined or press fit together, so that hammer member 102 rotates together with the spindle 40. In other words, the hammer member 102 is rotatable or rotating. The hammer members 100 and 102 have cooperating ratcheting teeth 104 and 106, hammer members 100 and 102, which are conventional, for delivering the desired vibratory impacts to the output spindle 40 when the tool is in the hammer-drill mode of operation. The hammer members 100, 102 can be made of hardened steel. Alternatively, the hammer members 100, 102 can be made of another suitable hard material.
A spring 108 is provided to forwardly bias the output spindle 40 as shown in FIG. 14, thereby tending to create a slight gap between opposed faces of the hammer members 100 and 102. In operation in the hammer mode as seen in FIG. 17, a user contacts a drill bit against a workpiece exerting a biasing force on the output spindle 40 that overcomes the biasing force of spring 108. Thus, the user causes cooperating ratcheting teeth 104 and 106 of the hammer members 100 and 102, respectively, to contact each other, thereby providing the hammer function as the rotating hammer member 102 contacts the non-rotating hammer member 100.
Referring to FIGS. 24 and 25, axially movable hammer member 100 includes three equally spaced projections 250 that extend radially. The radial projections 250 can ride in corresponding grooves 266 in the forward housing 16. An axial groove 252 can be located along an exterior edge of each radial projection 250. The axial groove 252 provides a support surface along its length. Positioned within each axial groove 252 is a support guide rod 254 that provides a cooperating support surface at its periphery. Thus, the axial groove 252 operates as a support aperture having a support surface associated therewith, and the guide rod 254 operates as a support member having a cooperating support surface associated therewith.
Located on each hammer support rod 254 is a return spring 256. The return spring 256 is a biasing member acting upon the non-rotating hammer member to bias the non-rotating hammer toward the non-hammer mode position. The proximal end of each hammer support rod 254 can be press-fit into one of a plurality of first recesses 260 in the forward housing 16. This forward housing 16 can be the gear case housing. This forward housing 16 can be wholly or partially made of aluminum. Alternatively, the forward housing 16 can be wholly or partially made of plastic or other relatively soft material. The plurality of first recesses can be located in the relatively soft material of the forward housing 16. The distal end of each hammer support rod 254 can be clearance fit into one of a plurality of second recesses 262 in the end cap 28. The end cap 28 can be wholly or partially made of a material which is similar to that of the forward housing 16. Thus, the plurality of second recesses 262 of the end cap 28 can be located in the relatively soft material. The end cap 28 is attached to the forward housing member 16 with a plurality of fasteners 264 which can be screws.
The support rods 254 can be made of hardened steel. Alternatively, the support rods 254 can be made of another suitable hard material, so that the support rods are able to resist inappropriate wear which might otherwise be caused by the axially movable hammer member 100, during hammer operation. The hammer members 100, 102 can be made of the same material as the support rods 254. To resist wear between the support rods 254 (which can be of a relatively hard material) and the recesses 260, 262 (which can be of a relatively soft material), the recesses 260, 262 can have a combined depth so they can together accommodate at least about 25% of the total axial length of the support rod 254; or alternatively, at least about 30% the length. In addition, press-fit recesses 260 can have a depth so it accommodates at least about 18% of the total axial length of the support rod 254; or alternatively, at least about 25% of the length. Further, each of the recesses 260, 262 can have a depth of at least about 12% of the axial length of the support rod 254.
Thus, the hammer member 100 is permitted limited axial movement, but not permitted to rotate with the axial spindle 40. The support rods 254 can provide the rotational resistance necessary to support the hammer member 100 during hammer operation. As a result, the projections 250 of the typically harder hammer member 100 can avoid impacting upon and damaging the groove 266 walls of the forward housing 16. This can permit the use of an aluminum, plastic, or other material to form the forward housing 16.
On the side of hammer member 100 opposite ratcheting teeth 104, a cam 112 having a cam arm 114 and a series of ramps 116 is rotatably disposed axially adjacent to the axially movable hammer member 100. During rotation of the mode collar 26 into the "hammer-drill" mode, the cam arm 114 is engaged and thereby rotated by the hammer cam drive rib 86 (FIG. 4). Upon rotation of the cam 112, the series of ramps 116 defined on the cam 112 ride against complementary ramps 118 defined on an outboard face of the axially movable hammer member 100 to urge the movable hammer member 100 into a position permitting cooperative engagement with the rotating hammer member 102. Spring 184 is coupled to cam arm 144, so that upon rotation of the mode collar 26 backwards, out of the hammer mode, the spring 184 anchored by bolt 266 rotates cam 112 backwards.
With continued reference to FIGS. 10-17, the transmission 22 will now be described in greater detail. The transmission 22 generally includes a low output gear 120, a high output gear 122, and a shift sub-assembly 124. The shift sub-assembly 124 includes a shift fork 128, a shift ring 130, and a shift bracket 132. The shift fork 128 defines an annular tooth 136 (FIG. 12) that is captured within a radial channel 138 defined on the shift ring 130. The shift ring 130 is keyed for concurrent rotation with the output spindle 40. The axial position of the shift ring 130 is controlled by corresponding movement of the shift fork 128. The shift ring 130 carries one or more pins 140. The pins 140 are radially spaced from the output spindle 40 and protrude from both sides of the shift ring 130. One or more corresponding pockets or detents (not specifically shown) are formed in the inner face of the low output gear 120 and the high output gear 122, respectively. The pins 140 are received within their respective detent when the shift ring 130 is shifted axially along the output spindle 40 to be juxtaposed with either the low output gear 120 or the high output gear 122.
The shift fork 128 slidably translates along a static shift rod 144 upon axial translation of the mechanical speed shift pin 90. A first compliance spring 146 is disposed around the static shift rod 144 between the shift bracket 132 and the shift fork 128. A second compliance spring 148 is disposed around the static shift rod 144 between the shift bracket 132 and a cover plate 150. The first and second compliance springs 146 and 148 urge the shift fork 128 to locate the shift ring 130 at the desired location against the respective low or high output gear 120 or 122, respectively. In this way, in the event that during shifting the respective pins 140 are not aligned with the respective detents, rotation of the low and high output gears 120 and 122 and urging of the shift fork 128 by the respective compliance springs 146 and 148 will allow the pins 140 to will be urged into the next available detents upon operation of the tool and rotation of the gears 120, 122. In sum, the shift sub-assembly 124 can allow for initial misalignment between the shift ring 130 and the output gears 120 and 122.
An output member 152 of the motor 20 (FIG. 18) is rotatably coupled to a first reduction gear 154 (FIG. 12) and a first and second reduction pinions 156 and 158. The first and second reduction pinions 156, 158 are coupled to a common spindle. The first reduction pinion 156 defines teeth 160 that are meshed for engagement with teeth 162 defined on the low output gear 120. The second reduction pinion 158 defines teeth 166 that are meshed for engagement with teeth 168 defined on the high output gear 122. As can be appreciated, the low and high output gears 120 and 122 are always rotating with the output member 152 of the motor 20 by way of the first and second reduction pinions 156 and 158. In other words, the low and high output gears 120 and 122 remain in meshing engagement with the first and second reduction pinions 156 and 158, respectively, regardless of the mode of operation of the drill 10. The shift sub-assembly 124 identifies which output gear (i.e., the high output gear 122 or the low output gear 120) is ultimately coupled for drivingly rotating the output spindle 40 and which spins freely around the output spindle 40.
With specific reference now to FIGS. 14-17, shifting between the respective modes of operation will be described. FIG. 14 illustrates the hammer-drill 10 in the mode "1". Again, mode "1" corresponds to the electronic low speed setting. In mode "1", the distal tip 96 of the electronic speed shift pin 92 is located on the electronic shift pin plateau 84 of the mode collar 26 (see also FIG. 6). As a result, the electronic speed shift pin 92 is translated to the right as viewed in FIG. 14. As will be described in greater detail later, translation of the electronic speed shift pin 92 causes a proximal end 172 of the electronic speed shift pin 92 to slidably translate along a ramp 174 defined on an electronic speed shift switch 178. Concurrently, the mechanical speed shift pin 90 is located on the mechanical shift pin plateau 78 of the mode collar 26 (see also FIG. 6). As a result, the mechanical speed shift pin 90 is translated to the right as viewed in FIG. 14. As shown, the mechanical speed shift pin 90 urges the shift fork 128 to the right, thereby ultimately coupling the low output gear 120 with the output spindle 40. Of note, the movable and fixed hammer members 100 and 102 are not engaged in mode "1".
FIG. 15 illustrates the hammer-drill 10 in the mode "2". Again, mode "2" corresponds to the mechanical low speed setting. In mode "2", the distal tip 96 of the electronic speed shift pin 92 is located on the electronic shift pin valley 80 of the mode collar 26 (see also FIG. 7). As a result, the electronic speed shift pin 92 is translated to the left as viewed in FIG. 15. Translation of the electronic speed shift pin 92 causes the proximal end 172 of the electronic speed shift pin 92 to slidably retract from engagement with the ramp 174 of the electronic speed shift switch 178. Retraction of the electronic speed shift pin 92 to the left is facilitated by a return spring 180 captured around the electronic speed shift pin 92 and bound between a collar 182 and the cover plate 150.
Concurrently, the mechanical speed shift pin 90 is located on the mechanical shift pin plateau 78 of the mode collar 26 (see also FIG. 7). As a result, the mechanical speed shift pin 90 remains translated to the right as viewed in FIG. 15. Again, the mechanical speed shift join 90 locating the shift fork 128 to the position shown in FIG. 15 ultimately couples the low output gear 120 with the output spindle 40. Of note, as in mode 1, the movable and fixed hammer members 100 and 102 are not engaged in mode "2". Furthermore, shifting between mode 1 and mode 2 results in no change in the axial position of one of the shift pins (shift pin 90), but results in an axial change in the position of the other shift pin (shift pin 92) as a result of the cam surface 72 of the mode collar 26.
FIG. 16 illustrates the hammer-drill 10 in the mode "3". Again, mode "3" corresponds to the mechanical high speed setting. In mode "3", the distal tip 96 of the electronic speed shift pin 92 is located on the electronic shift pin valley 80 of the mode collar 26 (see also FIG. 8). As a result, the electronic speed shift pin 92 remains translated to the left as viewed in FIG. 16. Again, in this position, the proximal end 172 of the electronic speed shift pin 92 is retracted from engagement with the ramp 174 of the electronic speed shift switch 178. Concurrently, the mechanical speed shift pin 90 is located on the mechanical shift pin valley 74 of the mode collar 26 (see also FIG. 8). As a result, the mechanical speed shift pin 90 is translated to the left as viewed in FIG. 16. Again, the mechanical speed shift pin 90 locating the shift fork 128 to the position shown in FIG. 16 ultimately couples the high output gear 120 with the output spindle 40. Of note, the movable and fixed hammer members 100 and 102 are not engaged in mode "3". Again, shifting between mode 2 and mode 3 results in no change in the axial position of one of the shift pins (shift pin 92), but results in an axial change in the position of the other shift pin (shift pin 90) as a result of the cam surface 72 of the mode collar 26.
FIG. 17 illustrates the hammer-drill 10 in the "hammer-drill" mode. Again, the "hammer-drill" mode corresponds to the mechanical high speed setting with the respective movable and fixed hammer members 100 and 102 engaged. In the "hammer-drill" mode, the distal tip 96 of the electronic speed shift pin 92 is located on the electronic shift pin valley 80 of the mode collar 26 (see also FIG. 9). As a result, the electronic speed shift pin 92 remains translated to the left as viewed in FIG. 17. Again, in this position the proximal end 172 of the electronic speed shift pin 92 is retracted from engagement with the ramp 174 of the electronic speed shift switch 178. Concurrently, the mechanical speed shift pin 90 is located on the mechanical shift pin valley 74 of the mode collar 26 (see also FIG. 9). As a result, the mechanical speed shift pin 90 remains translated to the left as viewed in FIG. 17. Thus, in shifting between mode 3 and mode 4, both the electronic speed shift pin 92 and the mechanical shift pin 90 remain in the same axial position. As discussed below, however, another (non-speed) mode selection mechanism changes position. Specifically, cam 112 is caused to rotate (into an engaged position) by cooperation between the cam drive rib 86 of the mode collar 26 and the cam arm 114 of the cam 112. A return spring 184 (FIG. 10) urges the cam 112 to rotate into an unengaged position upon rotation of the mode collar 26 away from the "hammer-drill" mode.
In the "hammer-drill" mode, however, the respective axially movable and hammer member 100 is axially moved into a position where it can be engaged with rotating hammer member 102. Specifically, the manual application of pressure against a workpiece (not seen), the output spindle moves axially back against biasing spring 108. This axial movement of the output spindle 40 carries the rotating hammer member 102 is sufficient that, since the axially movable hammer member 100 has been moved axially forward, the ratchets 104, 106 of the hammer members 100 and 102, respectively, are engagable with each other. Moreover, selection of the "hammer-drill" mode automatically defaults the shift sub-assembly 124 to a position corresponding to the mechanical high speed setting simply by rotation of the mode collar 26 to the "hammer-drill" setting 56 and without any other required actuation or settings initiated by the user. In other words, the mode collar 26 is configured such that the hammer mode can only be implemented when the tool is in a high speed setting.
With reference now to FIGS. 18 and 19, the electronic speed shift switch 178 will be described in greater detail. The electronic speed shift switch 178 generally includes an electronic speed shift housing 186, an intermediate or slide member 188, return springs 190, an actuation spring 192, and a push button 194. Translation of the electronic speed shift pin 92 to the position shown in FIG. 14 (i.e., the electronic low speed setting) corresponding to mode 1 causes the proximal end 172 of the electronic shift pin 92 to slidably translate along the ramp 174 and, as a result, urge the slide member 188 leftward as viewed in FIG. 19.
In the position shown in FIG. 18, the compliance spring applies a biasing force to the push button 194 that is weaker than the biasing force of the push button spring (not shown) inside the switch. As the slide member 188 is moved to the position shown in FIG. 19, The biasing force from the actuation spring 192 pressing on the push button 194, overcomes the resistance provided by the pushbutton 194. Thus, the large movement of the slide member 188 is converted to the small movement used to actuate the push button 194 via the actuation spring 192. The return springs 190 operate to resist inadvertent movement of the slide member 188, and to return the slide member 188 to its position in FIG. 18.
Of note, the slide member 188 is arranged to actuate in a transverse direction relative to the axis of the output spindle 40. As a result, inadvertent translation of the slide member 188 is reduced. Explained further, reciprocal movement of the hammer-drill 10 along the axis 30 may result during normal use of the hammer-drill 10 (i.e., such as by engagement of the hammer members 100 and 102 while in the "hammer-drill" mode, or other movement during normal drilling operations). By mounting the electronic speed shift switch 178 transverse to the output spindle 40, inadvertent translation of the slide member 188 can be minimized.
As shown from FIG. 18 to FIG. 19, the push button 194 is depressed with enough force to activate the electronic speed shift switch 178. In this position (FIG. 19), the electronic speed shift switch 178 communicates a signal to a controller 200. The controller 200 limits current to the motor 20, thereby reducing the output speed of the output spindle 40 electronically based on the signal. Since the actuation is made as a result of rotation of the mode collar 26, the electronic actuation is seamless to the user. The electronic low speed mode can be useful when low output speeds are needed such as, but not limited to, drilling steel or other hard materials. Moreover, by incorporating the electronic speed shift switch 178, the requirement of an additional gear or gears within the transmission 22 can be avoided, hence reducing size, weight and ultimately cost. Retraction of the electronic speed shift pin 92 caused by a mode collar selection of either mode "2", "3", or "hammer-drill", will return the slide member 188 to the position shown in FIG. 18. The movement of the slide member 188 back to the position shown in FIG. 18 is facilitated by the return springs 190. While the electronic speed shift switch 178 has been described as having a slide member 188, other configurations are contemplated. For example, the electronic speed shift switch 178 may additionally or alternatively comprise a plunger, a rocker switch or other switch configurations.
Referring now to FIGS. 1, 11, and 23, another aspect of the hammer-drill 10 is illustrated. As mentioned above, the hammer-drill 10 includes the rearward housing 14 (i.e., the motor housing) for enclosing the motor 20 and the forward housing 16 (i.e., the transmission housing) for enclosing the transmission 22. The forward housing 16 includes a gear case housing 149 (FIGS. 1 and 23) and a cover plate 150 (FIGS. 11 and 23).
The gear case housing 149 defines an outer surface 179. It is understood that the outer surface 179 of the gear case housing 149 partially defines the overall outer surface of the hammer-drill 10. In other words, the outer surface 179 is exposed to allow a user to hold and grip the outer surface 179 during use of the hammer-drill 10.
The cover plate 150 is coupled to the gear case housing 149 via a plurality of first fasteners 151. As shown in FIG. 23, the first fasteners 151 are arranged in a first pattern 153 (represented by a bolt circle in FIG. 23). The first fasteners 151 can be located within the periphery of the gear case housing 149 and can hold the cover plate 150 against a lip 290 within the gear case housing 149. In one embodiment, the forward housing 16 includes a seal (not shown) between the gear case housing 149 and the cover plate 150, which reduces leakage of lubricant (not shown) out of the forward housing 16.
The forward housing 16 and the rearward housing 14 are coupled via a plurality of second fasteners 159 (FIG. 1). In the embodiment represented in FIG. 23, the second fasteners 159 are arranged in a second pattern 161 (represented by a bolt circle in FIG. 23). As shown, the second pattern 161 of the second fasteners 159 has a larger periphery than the first pattern 153 of the first fasteners 151. In other words, the second fasteners 159 are further outboard than the first fasteners 151. Thus, when the forward housing 16 and the rearward housing 14 are coupled, the forward housing 16 and the rearward housing 14 cooperate to enclose the first fasteners 151.
Also, in the embodiment shown, the cover plate 150 can include a plurality of pockets 155. The pockets 155 can be provided such that the heads of the first fasteners 151 are disposed beneath an outer surface 157 of the cover plate 150. As such, the first fasteners 151 are unlikely to interfere with the coupling of the rearward and forward housings 14, 16.
The cover plate 150 also includes a plurality of projections 163 that extend from the outer surface 157. The projections 163 extend into the rearward housing 14 to ensure proper orientation of the forward housing 16. The cover plate 150 further includes a first aperture 165. The output member 152 of the motor 20 extends through the aperture 165 to thereby rotatably couple to the first reduction gear 154 (FIG. 12).
Also, as shown in FIG. 13, the cover plate 150 includes a support 167 extending toward the interior of the forward housing 16. The support 167 is generally hollow and encompasses the output spindle 40 such that the output spindle 40 journals within the support 167.
As shown in FIGS. 18, 19, and 23 and as described above, the proximal end 172 electronic speed shift pin 92 extends out of the forward housing 16 through the cover plate 150 so as to operably engage the electronic speed shaft switch 178 (FIG. 19). Also, as described above, the return spring 180 is disposed around the electronic speed shift pin 92 and is bound between the collar 182 and the cover plate 150. Thus, the return spring 180 biases the electronic speed shift pin 92 against the cover plate 150 toward the interior of the forward housing 16.
Furthermore, as described above and seen in FIGS. 11 and 13, static shift rod 144 is supported at one end by the gear case cover plate 150. In addition, the second compliance spring 148 that is disposed about the static shift rod 144 and extends between the shift bracket 132 and the cover plate 150. As such, the second compliance spring 148 can be biased against the shift bracket 132 and the cover plate 150.
The configuration of the cover plate 150 and the outer shell 149 of the forward housing 16 allows the transmission 22 to be contained independent of the other components of the hammer-drill 10. As such, manufacture of the hammer-drill 10 can be facilitated because the transmission 22 can be assembled substantially separate from the other components, and the forward housing 16 can then be subsequently coupled to the rearward housing 14 for added manufacturing flexibility and reduced manufacturing time.
Furthermore, the cover plate 150 can support several components including, for instance, the output spindle 40 the static shift rod 144 and the electronic shift rod 92. In addition, several springs can be biased against the cover plate, for instance, compliance spring 148 and spring 180. Thus, proper orientation of these components are ensured before the rearward housing 14 and the forward housing 16 are coupled. In addition, the cover plate 150 holds the transmission and shift components and various springs in place against the biasing forces of the springs. As such, the cover plate 150 facilitates assembly of the hammer-drill 10.
Referring now to FIGS. 20 through 22, clutch details of an embodiment of the transmission 22 of the hammer drill 10 is illustrated. The transmission 22 can include a low output gear 220, a clutch member 221, a high output gear 222, and a shift sub-assembly 224. The shift sub-assembly 224 can include a shift fork 228, a shift ring 230, and a shift bracket 232.
As shown in FIG. 20, the clutch member 221 generally includes a base 223 and a head 225. The base 223 is hollow and tubular, and the head 225 extends radially outward from one end of the base 223. The base 223 encompasses the spindle 40 and is fixedly coupled (e.g., splined) thereto such that the clutch member 221 rotates with the spindle 40. The head 225 defines a first axial surface 227, and the head 225 also defines a second axial surface 229 on a side opposite to the first axial surface 227.
The base 223 of the clutch member 221 extends axially through the bore of the low output gear 220 such that the low output gear 220 is supported by the clutch member 221 on the spindle 40. The low output gear 220 can be supported for sliding axial movement along the base 223 of the clutch member 221. Also, the low output gear 220 can be supported for rotation on the base 223 of the clutch member 221. As such, the low output gear 220 can be supported for axial movement and for rotation relative to the spindle 40′.
The transmission 22 also includes a retaining member 231. In the embodiment shown, the retaining member 231 is generally ring-shaped and disposed within a groove 233 provided on an end of the base 223. As such, the retaining member 231 is fixed in an axial position relative to the first axial surface 227 of the base 223.
The transmission 22 further includes a biasing member 235. The biasing member 235 can be a disc spring or a conical (i.e., Belleville) spring. The biasing member 235 is supported on the base 223 between the retaining member 231 and the low output gear 220. As such, the biasing member 235 biases a face 236 of the low output clutch 220 against thee face 227 of the base 223 by pressing against the retaining member 231 and low output gear 220.
The clutch member 221 also includes at least one aperture 241 (FIG. 20) on the second axial surface 229. In the embodiment shown, the clutch member 221 includes a plurality of apertures 241 arranged in a pattern corresponding to that of the pins 240 of the shift ring 230 (FIG. 21). As will be described below, axial movement of the shift ring 230 causes the pins 240 to selectively move in and out of corresponding ones of the apertures 241 of the clutch member 221 such that the shift ring 230 selectively couples to the clutch member 221.
Furthermore, the head 225 of the clutch member 221 includes a plurality of ratchet teeth 237 on the first axial surface 227 thereof, and the low output gear 220 includes a plurality of corresponding ratchet teeth 239 that selectively mesh with the ratchet teeth 237 of the clutch member 221. More specifically, as shown in FIG. 22, the ratchet teeth 237 of the clutch member 221 are cooperate with the ratchet teeth 239 of the low output gear 220. Each tooth of the ratchet teeth 237 and 239 can include at least one cam surface 245 and 249, respectively. As will be described, as the clutch member 221 is coupled to the low output gear 220, the ratchet teeth 237 mesh with corresponding ones of the ratchet teeth 239 such that the cam surfaces 245, 249 abut against each other.
As shown in FIG. 22, the cam surfaces 245, 249 of the low output gear 220 and the clutch member 221 are provided at an acute angle a relative to the axis 30 of the spindle 40. As will be described below, when the clutch member 221 and the low output gear 220 are coupled, an amount of torque is able to transfer therebetween up to a predetermined threshold. This threshold is determined according to the angle α of the cam surfaces 245, 249 and the amount of force provided by the biasing member 235 biasing the low output gear 220 toward the clutch member 221.
When the hammer-drill 10 is in the low speed setting (electrical or mechanical) and torque transferred between the low output gear 220 and the clutch member 221 is below the predetermined threshold amount, the corresponding cam surfaces 245, 249 remain in abutting contact to allow the torque transfer. However, when the torque exceeds the predetermined threshold amount (e.g., when the drill bit becomes stuck in the workpiece), the cam surfaces 245 of the clutch member 221 cam against the cam surfaces 249 of the low output gear 220 to thereby move (i.e., cam) the low output gear 220 axially away from the clutch member 221 against the biasing force of the biasing member 235. As such, torque transfer between the clutch member 221 to the low output gear 220 is interrupted and reduced.
It will be appreciated that the clutch member 221 limits the torque transfer between the output member 152 of the motor 20 and the spindle 40 to a predetermined threshold. It will also be appreciated that when the hammer-drill 10 is in the mechanical high speed setting, torque transfers between the second reduction pinion 258 and the spindle 40 via the high output gear 222, and the clutch member 221 is bypassed. However, the gear ratio in the mechanical high speed setting can be such that the maximum torque transferred via the high output gear 222 is less than the predetermined threshold. In other words, the transmission 22 can be inherently torque-limited (below the predetermined threshold level) when the high output gear 222 provides torque transfer.
Thus, the clutch member 221 protects the transmission 22 from damage due to excessive torque transfer. Also, the hammer-drill 10 is easier to use because the hammer-drill 10 is unlikely to violently jerk in the hands of the user due to excessive torque transfer. Furthermore, the transmission 22 is relatively compact and easy to assemble since the clutch member 221 occupies a relatively small amount of space and because only one clutch member 221 is necessary. Additionally, the transmission 22 is relatively simple in operation since only the low output gear 220 is clutched by the clutch member 221. Moreover, in one embodiment, the hammer-drill 10 includes a pusher chuck for attachment of a drill bit (not shown), and because of the torque limiting provided by the clutch member 221, the pusher chuck is unlikely to over-tighten on the drill bit, making the drill bit easier to remove from the pusher chuck.
Additional locking details of the shifting mechanism are illustrated in FIG. 26. For clarity, these additional locking details have been omitted from the remaining drawings. Thus, as described hereinafter, the transmission shifting mechanism described herein can include a locking mechanism to maintain the transmission in the high speed gear mode. This high speed gear mode can be the only mode in which the hammer mode can also be active. This locking mechanism, therefore, can resist any tendency of the pins 140 of the shift ring 138 to walk out of the corresponding holes 270 in the high speed gear 122, during hammer mode operation.
The static shift rod 144 operates as a support member for supporting the shift bracket 132. The shift bracket 132 or shift member is mounted on the static shift rod 144 in a configuration permitting movement of the shift member along the outer surface of the shift rod between a first mode position corresponding to a first mode of operation and a second mode position corresponding to a second mode of operation. The shift bracket 132 can also mounted on the static shift rod 144 in a configuration permitting limited rotational or perpendicular (to the shift surface) movement between a lock position and an unlock position in a direction that is substantially perpendicular to the shift surface. As illustrated, the shift bracket includes two apertures 282, 284 through which the static shift rod 144 extends. At least one of the apertures 282 can be slightly larger than the diameter of the static shift rod to allow the limited rotational or perpendicular movement of the shift bracket 144.
A groove 268 can be located in the static shift rod 144. The groove 268 has a sloped front surface 272 and a back surface 274 that is substantially perpendicular to the axis of the static shift rod 144. Located on the static shift rod 144 and coupled to the shift bracket 132 is a lock spring member 276. The lock spring 276 fits into an opening 278 in the shift bracket 132, so that the lock spring 276 moves along the axis of the static shift rod 144 together with the shift bracket 132. Thus, when return spring 148 moves the shift bracket 132 into the high speed gear position, the shift bracket 132 aligns with the groove 268. The lock spring 276 exerts a force in a direction of arrow X, which pushes the shift bracket 132 into the groove 268.
The biasing force in the direction of arrow X provided by the lock spring 276 retains the shift bracket 132 in the groove 268. In combination with the perpendicular back surface 274 of the groove 268, which operates with the shift bracket 132 to provide cooperating lock surfaces, the lock spring 276 prevents shift bracket 132 from moving backwards along the static shift rod 144 during hammer mode operation. In this way, the axial forces that are repeatedly exerted on the transmission during hammer mode operation can be resisted by the shifting mechanism.
When shifting out of the high speed gear mode, shift pin 90 operates as an actuation member and exerts a force in the direction of arrow Y. Since this force is offset from the surface of the static shift rod 144, upon which the shift bracket 132 is mounted, this force exerts a moment on the shift bracket 132; thereby providing a force in the direction of arrow Z. This force along arrow Z exceeds the biasing spring force along arrow X, which causes the shift bracket 132 to move out of the groove 268; thereby allowing movement into the low speed gear mode. The locking spring member 276 includes a protrusion 280 which extends into a cooperating opening 282 of the shift bracket 132 to prevent the opposite side of the shift bracket 132 from entering the groove 268 in response to the force in the direction of arrow Z. The protrusion 280 can be in the form of a lip.
For clarity, the direction of the force along arrow X is perpendicular to the axis of the static shift rod 144 and toward the force along arrow Y. The direction of the force along arrow Z is opposite to that of arrow X. The direction of the force along arrow Y is parallel to the axis of the static shift rod 144 and toward the force along arrow X. In addition, the force along arrow Y is spaced away from the axis of the static shift rod 144, so that its exertion on shift bracket 132 generates a moment that results in the force along arrow Z, which opposes the force along arrow X.

Q: How to read by multiple lines instead of line-by-line I see that in my code I can modify a line if the entire code is based on that line.  Example:
this is an example Happy Holidays
.  However if the
 tag is located on a second line the code will pass that line.
What is the best way to detect until the line ends for certain tags?

A: Simple answer is: do not use shell to parse XML. Use a XML parser instead, e.g. one of the numerous for Perl: XML::Parser, XML::Simple, or any other language. For HTML, HTML::Parser is an option (if we stay with Perl).
If you want to use bash, you can play with the read built-in and a loop a bit.

A: Text utilities work on lines (text lines being (not too long) sequences of non-NUL characters terminated by a newline character). awk is the one standard utility that can be told to work on record separated by other things than newline characters, that's why awk talks of records instead of lines.
For instance, you could use > as the record separator. As in:
awk -v RS='>' ...

Another approach is to swap the character you want to use as the record separator (for other tools than awk) with the newline character:
... |
  tr '\n>' '>\n' |
  sed ... |
  other-text-utility... |
  tr '\n>' '>\n'

Those assume that the things you want to modify don't include nested HTML tags as they would start new records.
That is replace

Q: Get POST value from select tag in Django 1.7 In my forms.py I have
class CollegeForm(forms.ModelForm):
    collegeName = forms.ModelChoiceField(label='Select College', queryset=College.objects.all(), widget=forms.Select(attrs={'class': 'form-control'}))

    class Meta:
        model = College
        fields = ('collegeName',)

In my views.py,
if(request.method =='POST'):
    college_form = CollegeForm(request.POST)
else:
    college_form = CollegeForm()
return render(request, 'market/product_list.html',{'college_form': college_form})

In my product_list.html file, I have

    {{ college_form.as_p }}

I want to dynamically update the content of the page based on what the user selects from the drop down list. Is there a way to do so by making an Ajax call? If yes, how?

A: The short answer is yes. But it very much depends on what it is that you are trying to do.

*

*Depending on how much of your page you want to change and in what way...you may not need an ajax call..you could send down the data in the initial request and use javascript to update the page in specific ways.

*If you have a lot of data for each selection then you could take a very simple route of doing a page load each time a new selection is made. (the user experience here is a bit clunky, but it can be effective).

*Finally, if you have a lot of data and want the slick experience you can use ajax. You will need to have an endpoint to provide you with the necessary data depending on the selection. If you go this route I recommend using some javascript framework like jquery. Here is the documentation on the ajax call.
Here is an example of what an ajax solution might look like. This is just a general outline and assuming you are using jquery. There are extra details that will depend on implementation specifics:
Your new views.py:
import json

from django.shortcuts import render
from django.http import HttpResponse

from forms import CollegeForm
from models import CollegeInfo

def original_endpoint(request):
    # ...
    if request.method == 'POST':
        college_form = CollegeForm(request.POST)
    else:
        college_form = CollegeForm()
    return render(request, 'market/product_list.html', {'college_form': college_form})

def college_data_endpoint(request, college_name):
    """
    Endpoint for sending back college-specific data

    Response sent back in json format to make for easier processing with javascript
    """

    # Get college-specific data from the db
    college = CollegeInfo.objects.get(id=college_name)

    # format it
    response_data = {
        'field1': college.field1,
        'field2': college.field2
    }

    return HttpResponse(json.dumps(response_data), content_type='application/json')

Changes to product_list.html:

    {{ college_form.as_p }}

    {# HTML form to fill in college info and possibly unhide #}


Detectives conduct follow-up investigations into the more serious crimes that occur in Coralville. During 2015, 142 viable cases received the attention of the Investigations Division.
Four detectives are assigned to the Criminal Investigations Division of the Coralville Police Department. Three detectives work general criminal investigations, while one detective is assigned full-time to drug investigations with the Johnson County Drug Task Force.


Based in Battersea, Motu serve up indulgent, home style Indian food – because us Brits sure love an Indian takeaway. The name come from the affectionate Hindi term for 'Fat Man' and if you order enough of their feasts for one which sees a main course come with Kachumber Raita, pappadums, mango chutney, naan, pilau rice, then the name might become fitting. Order it in the evening during the week or from midday at the weekend.
Inspired by the tiffin lunch boxes of India, Karma Cans are your very own dabbawala, cycling your lunch to you before 1pm. Sign up to the weekly menu and choose from the day's meat, fish or veggie option before 11am and it'll be with you a couple of hours later, with zero emissions and in reusable or compostable packaging. And, until Friday (18th November), every lunch delivery will come with a free sample of Vita Coco Coconut Oil. Earlier this week we had the date and sumac roasted salmon with brown rice salad – can we have it every day?!
#BigTasteSmallWaist – that's what Peardrop are all about. Healthy food that both looks and tastes great. And it doesn't matter what scale of delivery you need – you want a thousand granola bars? Not a problem. You want to order the office lunch boxes to eat outside when it's sunny? Done (also brownie points for being a great boss.) Dishes include the likes of roasted aubergine salad with yoghurt, tahini dressing, mint, sesame and pomegranate and salmon and edamame salad.
When it comes to healthy and imaginative lunch deliveries then look no further than Bonapeti. Delivering both lunch time and evening, the meals are plant based and include the likes of broad bean and parsley fritters with preserved lemon tabbouleh and vine tomatoes stuffed with butterbeans and feta, served with roasted cauliflower and mixed quinoa. They do puddings too, how does chocolate amaranth pudding with poached bananas, hazelnut, banana chips and cacao nib crumble sound? Yep great, we agree.
Delivering to most of London, Holy Cow are all about using the finest quality fresh ingredients to create their Indian dishes. If you want authentic Indian dish without an artificial colour or preservative in sight (because let's be honest, Indian takeaways are partial to a preservative or two) then go for Holy Cow – you can customise your dish too to make it milder, hotter or however you like it.
With a goal of making eating well easy, Potage operates from a purpose-built kitchen under a railway arch in Battersea. The menu is developed by a nutritionist and served in biodegradable boxes so you can feel good in more ways than one. The menu changes daily but expect chilli and soy glazed salmon with pak choi and brown rice, and chicken, saffron, sun-dried tomatoes and sweet potato salad. Doing a group lunch? Potage will deliver everything from olives to guacamole to mini chocolate brownies (we've had them – they're amazing), just order 24 hours in advance.
Delivering their fare to London offices, City Pantry work with an extensive range of vendors including Ahi Poke, Pollen + Grace and Wham Banh Mi so you don't have to move from your desk if you fancy a lobster lunch, Christmas dinner, or sushi platter. Set up a meal plan and get lunch delivered on a regular basis or organise one-off catering for a meeting or event. We like the feedback feature which means you can learn what your team like, and what didn't go down so well so that next time you'll be even more popular.
Sometimes a meal deal just won't cut it. For those days you want a hearty curry, Tiffin Planet is your port of call. Choose between lunch or dinner, veg or meat and set up your meal plan (there is a minimum of 7 meals and maximum of 30) and then select the size tiffin (tin) you'd like. The menu varies slightly across different areas of London but expect palak paneer, dal paratha and tadka dal.
Tired of soggy salad leaves? Pure have got your back. Dressing their salads last minute to avoid the sad soggy leaf, they also bake their wholegrain flatbreads and pastries daily and whizz up their smoothies and juices every morning. As well as the super salads we love the breakfast eggs for when another pot of instant porridge just won't cut it – they have the best selection of toppings we've seen; smoked salmon, ago, mushrooms, goats cheese, bacon, you name it. We love the little pots too for when you're hungry but not hungry enough for a huge portion. Want it by 12.30pm? Order by 10.45am, or if you work centrally, collect at one of their stores.
This one isn't strictly speaking a lunch delivery service, but Goose Box delivers boxed ingredients so you can create restaurant-quality dishes at home. From the people at 1 Lombard Street, simply select how many people you're cooking for and choose from scallop carpaccio, fallow deer tartare, pear and black truffle risotto… Dishes also come with a recipe card and a suggested wine so if you've had a busy day at work but got friends over for dinner, no one will ever know.

Our Summary of Treasure Island by Robert Louis Stevenson
Robert Louis Stevenson's work 'Treasure Island' is structured into six parts. Stevenson structures the work from the narrator's perspective. Jim Hawkins, the narrator, is the son of the Admiral Benbow Inn. The first part of the book introduces another character, Billy Bones; he is an old seaman who is staying at the inn. Bones dies by the end of the first part, leaving behind a map to secret treasure. Along with Squire Trelawney, Hawkins searches for the treasure. The second part of the book introduces the sea cook, who is a seaman with one leg. Long John Silver is hired to cook on the ship as Hawkins and the rest of the crew travel to Treasure Island to find the treasure. Conflict arises on the ship as Hawkins discovers that Silver is planning a mutiny. The third part further reveals the true character of Silver, as he kills one of his men. In the middle of the work, Stevenson takes the narration out of Hawkins' control and gives it to Livesey, who relates events happening on the island within which he is located. Hawkins controls the narration in part four. By the end of 'Treasure Island,' Silver's mutiny backfires, and only five men end up sharing the treasure.

Q: How to get the maximum in each bin of a 2D histogram in python I'm using numpy, in particular the histrogram2d function.
I am binning a 3D spatial distribution of points (arrays x,y and z) with a 2d histogram. For each point I have an associated density field d.
If I do something like that
import numpy as np
H, xedges, yedges = np.histogram2d(x,y,bins=200,weights=d)

The histogram H represent the sum of the density along the line-of-sight (in this case in the z-axis). This is pretty fast and easy considering that I'm working with very big arrays.
Now I want to go further and instead of plotting the sum of the density filed along the line-of-sight I would like to get the maximum of the density in each 2D bin.
I coded the possible solution:
from numpy import *
x=array([0.5,0.5,0.2,0.3,0.2,0.25,0.35,0.6,0.1,0.22,0.7,0.45,0.57,0.65])
y=array([0.5,0.5,0.28,0.18,0.85,0.9,0.44,0.7,0.1,0.22,0.7,0.45,0.54,0.65])
d=array([1,1,2,2,3,5,6,8,7,9,6,10,5,7])

bins=linspace(0,1,64)

idx=digitize(x,bins)
idy=digitize(y,bins)

img2=zeros((len(bins),len(bins)))

for i in arange(0,len(d)):
  dummy=idx[i]
  dummy2=idy[i]
  img2[dummy][dummy2]=max(d[i],img2[dummy][dummy2])

However the loop in the last lines might be really slow for a huge dataset. Any idea on how I can make it faster?

A: Here is how I would do it, sorry I don't have time to write up the code right now:

*

*Use numpy.ravel_multi_index to turn the 2d problem into a 1d problem.

*Take a look at the implementation of numpy.unique, you want to do something like that to get unique bin values, but you want to do it in such a way so that it also gives you the min/max of d at the same time. numpy.lexsort might also help here.

*To move back into 2d space it should be as simple as img2.flat[uniq_1d_bin_value] = bin_max
I hope that's enough to get you started. If you have trouble, you can post your code and let us know where you got stuck and maybe I, or someone else, can help put you on the right path again.

Q: Windows 7 x64 Professional UEFI install How can I install Windows 7 x64 Professional on my Samsung SSD EVO 850 (500 GB) with USB or DVD?

A: First you will have to make a bootable USB or DVD, you can do this for Windows 7 by downloading the .iso file, and using a piece of software like Rufus.
After that you have to boot form the USB or DVD, do this by plugging in the USB or inserting the DVD into a DVD reader. The PC should ask if you want to boot form the 'new bootable device' it found. If not, you will have to enter the BIOS, and change the boot priorities of the attached media.
Lastly, the installation will start, and the usual steps should be followed. If you don't know what options too choose etc... You can find a guide HERE. This guide also goes trough setting up boot priorities.

Bacon and Egg Cups can be made ahead and are a great grab and go breakfast for busy weekday mornings. They're also pretty enough to serve for a special weekend brunch and are naturally paleo, gluten-free, and Whole30.
Friends! Let me introduce you to my newest, favoritest things: Bacon and Egg Cups + Vital Proteins. They're everything I need in life right now.
So, we're talking bacon. That's right, smoky, can't-ever-get-enough-of BACON. Thick cut and alder smoked deliciousness. Is there any other way?
But wait, let's backtrack. The "crust" of these Bacon and Egg Cups is made from sweet potatoes and, if you will, a little aged cheddar. Think of it as a sweet potato hash brown nest. Then there's the bacon, but we've already been there. Crack an egg in the nest and nestle an asparagus spear and a cherry tomato on top and you're on your way breakfast heaven.
My original plan for these Bacon and Egg Cups was for them to be quick grab and go breakfasts. You know, for those mornings where you desperately need to press snooze an 11th time (read: every morning of my life.) Or when you want to send those kiddies off to school with bellies full of a healthy breakfast but have no intention of slaving away in the kitchen before the sun pokes its head up.
These delicious, hand-held breakfast cups were supposed to be quickly grabbed from the fridge to fill you up as you rushed out the door.
What I didn't expect was for them to be so darn pretty. Seriously guys, you could easily serve these at a girl's lunch or a Mother's Day brunch and they'll be met with rave reviews. A little salad on the side and you'll be set.
Have you guys heard about Vital Proteins before? Last year, when we were hanging out in Fernie for a month, one of the guys we were staying with (hi, Blaire!) raved about this stuff. He said he had done his research and this is the best collagen on the market. My Amazon cart quickly over flowed with three of every Vital Proteins product available. But … are you as bad as I am with online shopping and then not clicking the purchase button? Seriously, what's up with that? Now that I've actually tried Vital Proteins, I'm totally kicking myself for not ordering it sooner.
♡ It's made from pasture-raised collagen and gelatin. Read: happy cows!
♡ Collagen is the fountain of youth. Not joking. In the short while I've been using it, my skin looks younger and I'm so not complaining. Collagen is also key for healthy bones and healthy joints and is one of nature's best superfoods.
♡ Vital Proteins Collagen Peptides are SUPER versatile. I was honestly amazed at how easily they can be added to a recipe. They're completely flavorless and dissolves instantly in liquid, leaving nothing but a delicious creamy feel.
♡ Add some to your morning smoothie and you'll be amazed at how smooth and creamy your smoothie is. Their Chocolate Coconut Collagen Whey is my all-time smoothie favorite.
♡ Stir some into your soup or chili to help thicken and make it creamy.
♡ Blend some into a dip. Think guacamole, hummus, baba ghanoush, or even some tzatziki.
♡ Wisk some into your gravy.
♡ Stir a little through your morning oatmeal.
♡ Craving homemade ice cream? Chocolate Coconut Collagen Whey would make a delicious addition.
♡ In your morning coffee. Not. Even. Joking. Coffee + coconut oil + Vital Proteins + a whizz around in your blender = the BEST coffee ever!
So let me guess … you're asking, "How the heck can I get my hands on some Vital Proteins?" AmIRight? Thought so.
The best way to order Vital Proteins is either on Amazon or directly from their website.
If you make these Bacon and Egg Cups make sure you snap a pic and tag @theendlessmeal and @Vital Proteins on Instagram so I can like and comment on your photos. I love seeing TEM recipes you create!
Bacon and Egg Cups can be made ahead and are great to grab and go on busy weekday mornings. They're also pretty enough to serve for a special weekend brunch and are naturally paleo and gluten-free.
Lay the bacon on the parchment lined tray and bake in the oven for 10 minutes.
In a medium sized bowl, mix the grated sweet potato, 1 egg, the Vital Proteins Collagen Peptides and, of you're using, the cheddar cheese. Divide the sweet potatoes between the 12 muffin tins and press into the bottoms and up the sides. Bake in the preheated oven for 8 minutes.
Cut each bacon slice in half and lay 2 halves in each of the muffin cups, letting them overhang a little.
Carefully add one egg to each of the 12 muffins tins. I find it's easiest to do this by cracking them into a small bowl, one at a time, then pouring them into the muffin cups. Top with an asparagus spear and a cherry tomato half. Bake for 18-20 minutes, or until the whites are firmly set.
Remove from the oven and let them cool for 5 minutes in the muffin tin. Run a knife or an offset spatula around each to loosen it then carefully remove them. Set them on a paper towel to remove the oil that will be on their bottoms.
Sprinkle with a little pepper and smoked paprika and serve. The Bacon and Egg Cups best warm, but are also delicious straight from the fridge. Keep them covered in your fridge for up to 3 days.
If you know your muffin tin tends to stick (like mine always does) you may want to cut out 12 small rounds of parchment paper to put in the bottom of each muffin cup. Do this by folding a piece of parchment several times so you only have to cut out one circle.
So, so, so lovely!! Made them tonight, and one friend told me they were "elegant." They really are beautiful (and tasty!). I made with vegetarian bacon and skipped the vital proteins. Next time I'd add salt to the sweet potato mixture and sprinkle the tops of the egg cups with salt and a couple drops of olive oil to flavor them and prevent them from drying out. Very, very nice!
Such a great idea to use veggie bacon to make them vegetarian!!
This can be made ahead and are a great grab and go breakfast for busy weekday mornings. They're also pretty!!!
I've been crushing on this gorgeous dish for a week now and keep coming back to visit it, lol. This MUST be made!
You totally should! They're seriously so good!
intstant follow by the first post I see over here.
Love this. Such a great idea to keep the day going strong. Beautiful photos too!
