text: the tool , in accordance with this invention , as best seen in fig1 and in fig2 includes a handle 11 having a top surface 13 , a bottom surface 15 , two side surfaces 17 , a front end 19 and a back end 21 . extending at right angles from the bottom surface 15 and generally parallel to one another are two shanks 23 , namely an exterior shank 25 and an interior shank 27 , the exterior shank 27 being located at the front end 19 of the handle 11 and the interior shank 27 being located in a spaced relationship to the exterior shank 25 toward the front end 19 of the handle 11 . the top surface 13 and the bottom surface 15 of the handle 11 have substantially the same configuration . the front end 19 of the handle 11 is blunt . the distance between the top surface 13 and the bottom surface 15 is substantially constant and both side surfaces 17 thus have substantially the same width . at the back end 21 of the handle 11 , the side surfaces 17 are beveled to form a chisel section 29 with an edge 31 at the back end of the handle 11 . the edge 31 is generally aligned with both the exterior shank 25 and the interior shank 27 . at the location of the interior shank 27 , the distance between the two side surfaces 17 , as measured on the top surface 13 and the bottom surface 15 , is the greatest along the entire handle 11 forming a wide section 31 of the handle 11 . the top surface 13 and the bottom surface 15 are tapered from the wide section 33 to the front end 19 forming a front section 35 which is a minor portion of the length of the handle 11 . similarly , the top surface 13 and the bottom surface 15 of the handle 11 taper from the wide section 33 to the chisel section 29 forming a back section 37 which is the major part of the handle 11 . the chisel section 29 of the handle is even shorter than the front section 35 of the handle 11 . both the exterior shank 25 and the interior shank 27 have a square cross section . each shank 23 is secured to or is preferably formed with the handle 11 and 10 has an inner end 39 and an outer end 41 . the inner end 39 is secured to the handle 11 and the outer end 41 is remote from the handle 11 . fillets 43 are formed at the inner end 39 of each shank 23 with the bottom surface 15 of the handle 11 extending toward the front end 19 and the back end 21 of the handle . each shank 23 has two side surfaces 45 , a front surface 47 and a back surface 49 . the front surface 47 face the front end 19 of the handle 11 . the back surfaces 49 face the back end 21 of the handle 11 . the side surfaces 45 are substantially at right angles to both the front surface 47 and the back surface 49 . just beneath the fillet 43 at the back surface 49 of the exterior shank 25 at each intersection of the back surface 49 with both side surfaces 45 , notches 51 are formed . similarly , just beneath the fillet 43 at the front surface 47 of the interior shank 27 at each intersection on the front surface 47 of the interior shank 27 with the two side surfaces 45 , notches 51 are formed . preferably , each shank 23 is one - half inch square . the exterior shank 25 has a generally constant cross section from the fillets to the outer end 41 thereof . the one - half inch square shank 03 provides a driver for use in a socket 53 having a one - half inch drive opening . the interior shank 27 also has a one - half inch square cross section but at the outer end 41 , for a minor portion 55 of the length of the interior shank 27 , has a reduced cross section , preferably to three - eights of an inch in cross section . it should be noted that alternate shank dimension , as for example , those consistent with metric tooling , may also be used . the back surface 49 of the interior shank 27 extends from the fillet 43 to the outer end 41 , but the front surface 47 has an indentation 57 twice that of the indentation 59 at the side surfaces 45 of the interior shank 27 , as a result , the distance from the front surface 47 of the exterior shank 25 to the back surface 49 of the interior shank 27 remains substantially constant through the entire length of both the exterior shank 25 and the interior shank 27 . the distance from the front surface 47 of the exterior shank 25 to the back surface 49 of the interior shank 27 is preferably two inches and this dimension is critical as it permits the tool effectively to fit the plugs 61 ( fig8 ) used in the pour openings of modern day drums 63 and also to provide the optimum space between the interior shank 27 and the exterior shank 25 for the most effective engagement of valve wheels 65 ( fig3 through fig7 ) and other tools where increased leverage is required . the reduced cross section of the outer end 41 of the interior shank 27 to a three - eights square provides a driver for a socket 67 having a three - eights square drive while preserving the needed two inch distance from the front surface 41 of the exterior shank 25 to the back surface 49 of the interior shank 27 . the uses of the tool are numerous and it is not possible to describe each and every one of the ways in which the tool can be beneficial . for example , adjustable open end wrenches ( not shown ) are well known and such wrenches have an opening at the end of the handle for various reasons only one of which is to hang the open end wrench on a wall . when such a adjustable open ended wrench engages a work piece ( not shown ) but cannot rotate the work piece because it is too tight , by placing the interior shank 27 into the opening of the open ended adjustable wrench with the exterior shank 25 engaging the edge of the handle of the open ended adjustable wrench greater leverage is provided . the vent plugs 69 of modem day drums , as best seen in fig9 are made with an indentation threeights of an inch square or one half inch square and the outer end 41 of the interior shank 27 fits the smaller opening and the outer end 41 of the exterior shank 25 fit the larger opening thereby providing easy turning of the vent plug 69 . some plugs 61 for pour openings in drums 63 have a square indentation which is one half inch square and which is readily engaged by the exterior shank 25 for easy turning of the plug 61 for pour openings . other plugs 61 for pour openings have a rib 71 diametrically located on the exterior of the plug , as best seen in fig8 and the combination of the exterior shank 25 and the interior shank 27 fit within the plug 61 and lock on the rib 71 to provide easy opening of the plug 61 . the edge 31 on the back end 21 on the handle 11 provides both a screw driver and a pry bar . both the interior shank 27 and the exterior shank 25 serve as a driver for sockets 53 , 67 , as shown in fig1 . a prime use of the tool is to assist in turning valve wheels 65 and similarly handles ( not shown ) in places such as power plants . in fig3 through fig7 various applications of the tool to the turning of valve wheels 65 is shown . in fig3 a small wheel 65 is shown on a valve . the wheel 65 , depicted in fig3 is small and has openings of limited size . the outer end 41 of the interior shank 27 fits into the openings on the handle between the spokes and permits the interior shank 27 to lock in place and the tool thereby provides much increased leverage for turning the valve wheel 65 . the valve wheel 65 shown in fig4 is of a different design but also is a comparatively small valve wheel 65 . the valve wheel 65 shown in fig4 has larger opening between the spokes than depicted in fig3 so the outer end 41 of but the exterior shank 25 and the interior shank 27 will not lock in the openings , however , with the exterior shank 25 in the opening and the interior shank 27 engaging the rim 73 , the same beneficial leverage is obtained to assist in turning the valve wheel 65 . in fig5 a comparatively moderately sized valve wheel 65 with comparatively thick spokes 75 in the valve wheel 65 . the tool is shown being used from the bottom of the valve wheel 65 but the tool can be used from the top down and that choice will depend upon the space available where the valve wheel 65 to be turned is situated . the shanks 23 of the tool are placed over one spoke 75 as seen in fig5 adjacent the intersection of the spokes 75 with the center hub 77 of the valve wheel 65 . the tool can be placed on any spoke 75 at any location on the spoke 75 depending on the leverage desired and most likely upon the ability to access the valve wheel 65 . in fig6 the same valve wheel 65 is shown , as is shown in fig5 but with the tool engaging the valve wheel 65 on the rim 73 and once again from the bottom up . this position on the rim 73 provides the maximum leverage to turn the wheel . in fig7 a comparative large valve wheel 65 is shown having comparatively thinner spokes 75 and rim 73 . here too the valve wheel 65 can be easily engaged by placing the exterior shank 25 at the intersection of a spoke and the rim 73 inside the rim 73 and the interior shank 27 against the outside of the rim 73 . the back section 37 of the handle 11 of the tool is tapered and this makes the tool very suitable as a drift pin to align holes ( not shown ) which is a need that does occur in a wide variety of situations . the edge 31 at the back end 21 of the tool can be used as a screw driver and also as a chisel or pry bar . it is to be understood that the drawings and description matter are in all cases to be interpreted as merely illustrative of the principles of the invention , rather than as limiting the same in any way , since it is contemplated that various changes may be made in various elements to achieve like results without departing from the spirit of the invention or the scope of the appended claims .
