text: referring now to fig1 a faucet 29 has a fixed body 1 on which is mounted a rotating component 11 which forms a delivery spout 14 . a cover 26 holds a mixing cartridge 21 in place inside the faucet 29 . the cartridge is equipped with an operating lever 25 . the lever 25 is shown in the form of an erect straight pole and is of the type commonly referred to as a “ joystick ”. as noted , this operating lever 25 can be moved in a first direction ( in the plane of the drawing as shown in fig1 ) to adjust the flow rate of mixed water between full flow and a shut - off position . in the drawings the control lever 25 is represented in the shut - off position . the operating lever can also be moved in a direction orthogonal to the first direction ( perpendicular to the plane of the drawing ) to regulate the mixing ratio between cold and hot water . in order for one to use the faucet properly , the user must know these directions of movement of the operating lever 25 . the delivery spout 14 is the only part of the faucet that has a prominent extension for indicating a well - defined direction . because many faucets have fixed delivery spouts , the user habitually takes the direction of the delivery spout 14 as reference for correct operation of the control lever 25 . the operator is thus instinctively or intuitively led to adopt the same criterion or orientation even when the delivery spout is adjustable . however , in this case , known faucets with adjustable spouts may mislead the user as shown in fig2 . the direction shown by the delivery spout 14 varies , as shown by the difference between a first centered position shown in phantom and a second rotated position . it is noted that the directions of movement of the lever 25 of the mixing cartridge , which is installed in a cavity or recess on the fixed body 1 of the faucet always remain unchanged and therefore has a variable relationship with the direction of the delivery spout 14 . as shown in fig2 when the spout is rotated , the two orthogonal axes of motion 31 , 33 of the control lever 25 become aslant with respect to the spout 14 , and the lever 25 become s aslant with respect to the spout 14 when in the shut - off position . in the invention , as is shown in fig4 the mixing cartridge 21 from which the control lever 25 extends is in fact installed in a cavity or recess 35 of a rotating component 11 . the component 11 has the delivery spout 14 integrally formed therewith . the cartridge is retained in the component 11 by the cover 26 which , in this case is secured to the rotating component 11 . the longitudinal axis of the cartridge 21 is aligned with the axis of rotation of the spout 14 . consequently , when the delivery spout 14 is adjusted in relation to the fixed body 1 , the rotating component 11 also turns , and the mixing cartridge 21 also rotates together with these parts , as illustrated in fig3 . therefore , the two axes of movement 31 , 33 of the operating lever 25 rotate in relation to the fixed body 1 , and remain constant or fixed with respect to the spout 14 . this fixed relation to the spout is shown in fig3 by the comparison of the two sets of orthogonal axis 31 , 33 . one set is in phantom corresponding to the phantom spout position and the second set is solid corresponding to the rotated solid spout position . the lever 25 also retains its own orientation with respect to the delivery spout 14 . if the spout 14 is rotated , the lever 25 moves with the spout as illustrated in fig3 . thus , the user may refer to the direction of the delivery spout 14 to determine the directions in which he must move the operating lever 25 to adjust the flow rate of water and the desired temperature . this is what he is accustomed to do when using faucets with fixed delivery spouts . furthermore , the operating lever 25 is always aligned over the spout 14 when in the shut - off position . reference now is made to fig4 and 6 to illustrate the recess or cavity 35 in the rotating component 11 . the cavity 35 that receives the mixing cartridge 21 offers a peripheral area or gap 12 , into which open out the lateral delivery openings 22 of the cartridge 21 ( which is of the open type ). the gap 12 communicates directly with passage 13 of the delivery spout 14 . it is apparent that , in modifications , the delivery spout 14 can be a component that is structurally separate from the rotating component 11 and is appropriately connected to component 11 . in addition , the recess or cavity 35 that receives the mixing cartridge 21 may not be directly formed in the rotating component 11 but in a component structurally separate and in turn installed in rotating component in order to ensure proper supply to the mixing cartridge 21 , a two - way hydraulic connection is between the rotating component 11 and the fixed body 1 of the faucet . this connection can be better seen with reference to fig5 and 6 . the rotating component 11 offers a projecting part 15 which offers a central opening 16 and a peripheral ring chamber 18 . the central opening 16 communicates , via a channel 17 , with a first inlet 23 to the cartridge 21 , while the peripheral ring chamber 18 communicates , via a channel 19 , with the second inlet 24 of the cartridge 21 . the fixed body 1 itself of the faucet has a cavity 2 intended to rotatably receive the projecting part 15 of the rotating component 11 . fixed body 1 has a central opening 3 which communicates with a connection 4 for a first supply pipe ( not shown ), and a peripheral ring chamber 5 which communicates via a passage 6 with a connection 7 for the second supply pipe ( not shown ). the parts described are designed so that , when the rotating component 11 is mounted on the fixed body 1 of the faucet , the central openings 3 and 16 can communicate with each other and chambers 5 and 18 communicate with each other . the respective passages are watertight due to seal 8 in opening 3 and ring seals 9 about ring chamber 18 . in this way the supply of cold and hot water to the cartridge 21 is ensured for every rotated position of the delivery spout 14 . the projecting part 15 of the rotating component 11 also offers a peripheral ring groove 20 into which receives a retaining screw 10 screwed through the fixed body 1 . the screw 10 mechanically couples the rotating component 11 in place axially without inhibiting its rotation . the ring groove 20 can be an incomplete arc for the purpose of limiting the field of rotation allowed to the rotating component 11 and to the delivery spout 14 . correspondingly the peripheral ring chambers 5 and 18 may be incomplete arcs along the circumference . it is understood that in other forms of embodiment , the two - way rotating hydraulic connection between the fixed body 1 and the rotating component 11 can be structured differently , as is known in the prior art for these hydraulic connections . also , multiple screws 20 may be received circumferentially about parts of the groove 20 to rotationally secure component 11 to the fixed body 1 . moreover , the control lever 25 is represented as a straight leg or pole but for certain applications it can be molded and shaped and used with the same internal valve mechanism . for example , the lever 25 may be contoured towards the delivery spout as is found in many known faucets . the central shut - off position of the “ joystick ” ever 25 always corresponds to the direction of the adjustable spout 14 . this shut - off position is selected so that the user is always certain of reaching complete shut - off by moving the lever towards the delivery spout . however , for certain applications , the shut - off position may be reversed , i . e . lifted up in opposition or away from spout 14 or may even be set at a 90 degree offset position for certain applications . in all situations , the shut - off position is permanently set with respect to the spout . secondly , the orientation of operation is also set with respect to the spout . the application of the invention therefore offers two major advantages for valves with “ joystick ” operating lever . the invention can naturally be applied also to faucets of different shapes and different valve operations from that represented in fig2 to 6 . for example , fig7 illustrates how the invention can be applied to a faucet on whose fixed body 1 is not of the so called “ joystick ” type . fig7 illustrates a valve that is subject to rotation about axis b — b for temperature adjustment and movement about an orthogonal axis for flow adjustment . the handle may be aesthetically contoured for ease of operation about axis b — b for temperature control and for movement about the orthogonal axis for flow control . moreover , in this example , the cartridge is mounted , in relation to the rotating component 11 , on the axis b — b which forms an angle with the axis of rotation a — a of the adjustable spout . both axis a — a and b — b are in the plane of the drawings and aligned with the center vertical plane of the spout 14 . these arrangements can turn out to be preferable in some cases , especially in view of certain shapes of the control lever . in this type of faucet , there are many shut - off positions along an arc where the lever is in a down position away from axis b — b . as such , the lever need not be aligned with the spout to completely shut off the faucet . the user still needs an orientation to correctly set the temperature . usually , the mix position is in the center of the adjustable field of operation and is centered with a fixed spout . in the present invention the center of the adjustable field is oriented with the adjustable spout and rotated therewith . the application of the invention provides the orientation for the correct operation of the control lever 25 . fig8 illustrates another embodiment of invention incorporating a ball valve that is not a cartridge format . in this embodiment , the rotating component 11 has a recess 41 shaped to receive valve seals 43 in the downstream ends of passages 17 and 19 that seat flushly against ball valve 44 . ball valve 44 has a control stem 46 passing through cap 26 and is affixed to operating lever 25 . the ball valve 44 is not in a cartridge format but is merely installed in appropriately shaped recess 41 in component 11 . nevertheless , as spout 14 is adjusted , component 11 is also rotated and carries with it the ball valve 44 and operating lever 25 such that the operation of lever 25 is always oriented with respect to the spout 14 . the actual internal drive components of the ball valve 44 are well known in the prior art and do not form part of this invention . it must be understood that the invention is not limited to the form of embodiments described and illustrated as examples . other variations and modifications are possible without departing from the scope and spirit of the present invention as defined by the appended claims .
