DETAILED DESCRIPTION

[0153] Referring to FIG. 1, what is shown is configuration of an embodiment of the invention as seen in a faucet mount in relation to a wash basin.

[0154] Referring to FIG. 2 what is shown a geometric positioning relation of the base 12 of a faucet spout 10, and distance 14, labeled a of said base 12 of said faucet spout 10 from said base 12 of spout 10 to a base 16 of a lever handle 20 of said faucet where said lever handle 20 is enabled with means for rotational motion when said lever handle 20 is attached to cartridge assembly 420. Said lever handle 20 rotation being enabled by connection to the upper portion of a spindle of a faucet cartridge valve. Said lever 20 is preferably configured with an upper flat surface region 201 and a lower curved surface region 202 to better to facilitate disbursement of liquid on said upper flat surface region 201 and adhesion of liquid to said lower curved surface region 202 thus substantially facilitating washing of total surface area of said lever 20 when said lever 20 is disposed to intercept line of flow 777 from spout portion 8. The members detergent reservoir 450 and spout escutcheon 977 are not shown in FIG. 2. Said lever 20 is preferably made from brass or stainless steel.

[0155] Referring to FIG. 3, what is shown is a view from the right of FIG. 2. Line 777 shows a direction of vertical flow of fluid from a faucet spout portion 8 of said spout 10 on said faucet mount. The horizontal distance 24, labeled b, between line 444 and line 777 and in the plane containing line 444 and line 777 is such that the vertical line 555 projects between line 444 and line 777 and in the plane containing line 444 and line 777 and where line 555 is the vertical line of axis 555 of said cartridge unit 420.

[0156] Referring to FIG. 4 and FIG. 2 geometric length 26 labeled c of said handle lever 20 can be related to the said geometric distance a and said geometric distance b by the inequality {square root over (a.sup.2+b.sup.2)}c. When said relation {square root over (a.sup.2+b.sup.2)}c exists in said faucet said lever handle 20 can be enabled to intersect said line of fluid flow 777 from said spout portion 8 of spout 10 of said faucet; thus said lever portion 20 can be exposed to interact with said fluid flowing from said spout portion 8 of said spout 10.

[0157] Referring to FIG. 5, what is shown is a geometric configuration for a single lever faucet unit.

[0158] Referring to FIG. 6, what is shown is an embodiment of a cartridge unit 420. Referring to FIG. 7 what is shown are the exploded components of said cartridge unit 420. As shown in FIG. 6 cartridge 420, includes a body 90, said body 90 has an exterior surface 64 and an interior passage 68. FIG. 8 shows a configuration of said body 90 while FIG. 8a shows the configuration of a cross-section of said body 90. As shown in FIG. 8 the exterior surface is preferably generally cylindrical in shape so as to be easily situated in a flow conduit for fluid and thus enable the action of an inline valve between the conduit and the outlet of a faucet. The body may be formed of a variety of materials such as metal, metal alloys or other utility compatible economical nonmetallic composite or thermoplastic.

[0159] The interior passage 68 of the body 90 defines a longitudinally extending passage 68 through the body as shown in FIG. 8a. Passage 68 preferably extends from an inlet opening 70, at the bottom of the body to a lateral outlet opening 82 at the top of the body. Passage 68 preferably has a cylindrical configuration conducive to use of rotating parts therein and can also have one or more sections or ones to accommodate the size and shape of various parts therein. As shown the passage has an upper portion 76 which is preferably of a narrower cross-sectional diameter as shown in FIG. 8a to correspond to the dimensions of the region 57 of said stem 104, and a lower wider cross-sectional diameter section 78 that is preferably wider to accommodate other parts of the valve such as a disk, sealing rings and rotatable base portion of said stem 104.

[0160] The body further includes at least one side opening 82 extending transversely through the body from the interior passage 68 to the exterior surface of the body 90. The side opening 82 is preferably located to be in keeping with current faucet design in that water or other fluid flowing upwards through the inlet end 70 of the body into passage 68 would encounter the stationary disk and pass through the opening therein when in the open valve mode until it entered the receiving area of the moveable disk and could then flow out the side opening 82 in the body to continue on to feed the faucet body and outlet of the faucet.

[0161] Thus, one or more side opening 82 for this embodiment should preferably be positioned to accommodate that flow out said side openings 82 in an unimpeded manner within the design. The opening is preferably rectangular for fluid flow characteristics but can have other configurations. As shown two such side openings 82 are shown which is compatible with the number of openings and receiving areas in the disk cartridge.

[0162] The openings 82 is preferably rectangular for fluid flow characteristics but can have other configurations. As shown two such side openings 82 are shown which is compatible with the number of openings and receiving areas in the disk cartridge.

[0163] FIG. 9 shows a configuration of body stop interceptor member 205 while FIG. 10 shows a cross-section of said member 205.

[0164] Referring to FIG. 8, said body 90 has an upper substantially flat surface 130 enabled with means for limiting the rotation of handle 20 and thus the rotation of stem 104. Said means for limiting the rotation of stem 104 is enabled by raised feature 60 and raised feature 61 where said feature 60 and said feature 61 are designed to limit the turning of said stem 104 by said lever 20 to a maximum predetermined angle of rotation; such limiting is enabled when said stop 60 and said stop 61 are rigidly connected to said upper surface 130 of said cartridge body 90. As will be shown said maximum predetermined angle of turn limits the range of motion of a moveable disc 102 against the openings of a fixed disc 112 and thus enables desired coordination of the various flow openings within a particular predetermined rotational range.

Said moveable disc 102 is further enabled with a preferably prismatic inclusion 100 where said inclusion 100 functions to tolerably accept extended tab 98 of the stem 57 thus enabling turning of moveable disc 102 against fixed disc 112 when said unit 57 is activated to rotate by activation of lever 20 for its utility and disc 102 enables fluid through 114 of fixed disc 112 into harbor 110 of said moveable disc 102.

[0180] Additionally, the upper surface of said moveable disc 102 is disposed to be described as a section of a cross-section of a cylinder defined by two parallel chords shaped to fit within a generally cylindrical portion of the passage 68 in the lower portion 78 of said passage 68. Said diametric inclusions 110 in the lower portion of moveable disc 102 function as fluid receiving harbors is the said moveable disc 102.

[0181] The movable disk 102 included within the body in passage 68 is enabled with means on its upper surface 104 configured to contact and interact with the bottom surface 96 of the lower end portion of the stem 66 in a rotatable relation. As shown, upper surface 104 is preferably configured with a slot 100 for receiving a tab 98 therein.

There are preferably two side wall portions defining preferably two fluid receiving areas 110 within the moveable disk 102. The receiving area 100 is configured so that when the disk 102 is rotated to align the receiving area 100 with the side opening 82 in the body 68 it will allow fluid flow out of the side opening of the body for feeding the faucet to which is installed with fluid entering the cartridge from a conduit through the open inlet 70 of the cartridge.

[0182] Referring to FIG. 16 what is shown is a stationary disk 112. Said disc 112 is fixed in position for interacting with moveable disc 102. Said fixed disc 112 is preferably provided with openings 114 extending through the stationary disk 112 for enabling passage of fluid flow from an inlet end 70 of the body 90 then into the passage 68, and through the stationary disk and then into the receiving area 110 of the moveable disk, and then out the side opening 82 of the body when the cartridge is in the open position mode. The stationary disk 112 is preferably enabled with lubricant containing pits 115; said lubricant in lubricant containing pits function to reduce friction between moveable disc 102 and stationary disc 112 thus further prolonging functional integrity of said moveable disc 102 and said stationary disc 112. Said fixed disc is further provided with diametric tabs 118; said tabs 118 enables the said disc 112 to be fixed in recesses in the interior passage 68 of the body cartridge 90.

[0183] Referring to FIG. 17 what is shown is another view of the stationary disc 112. Referring to FIG. 18, what is shown is a configuration of said fixed disc 112 positioned with diametric tabs 118 recessed in said body 90 of the cartridge unit. Referring to FIG. 19 what is shown is a view of the moveable disc 102. Referring to FIG. 20 what is shown is a relationship between said moveable disc 102 and said stationary disc 112 when cartridge valve unit 604 is in closure mode thus substantially resisting the flow of liquid from conduit 70 through passage 68 and to side openings 82. Referring to FIG. 21 what is shown is a relationship between said moveable disc 102 and said stationary disc 112 when said cartridge valve unit 420 is the open mode thus enabling the flow of liquid from conduit 70, through the passage 68 and to side openings 82. As will be shown said disabling and enabling of the flow of liquid through the valve cartridge unit is enabled when a lever handle 20, when fitted to portion 58 of the region 57 of the stem 104 shown in FIG. 14 can be turned to reduce and shut off flow. The handle 20 thus initiates the closing of the valve from the open mode of said valves and the opening of the valves from a closure mode of said valves when said handle 20 is initiated to turn.

[0184] Referring to FIG. 22 what is shown is a view from the side opening 82 of said cartridge unit 420 when said cartridge unit 420 is in closure mode. FIG. 23 shows a diametric cross-section of the view of FIG. 22 and here said diametric cross-section lies in a plane of symmetry across the most substantial dimensions of preferably rectangular prismatic slot 100 of said moveable disc 102.

[0185] Referring to FIG. 24, what is shown is a view of said cartridge 420 of FIG. 22 rotated through 90 degrees. FIG. 25 shows a diametric cross-section of the view of FIG. 24 where said diametric cross-section lies in a plane of symmetry across the lesser dimensions of preferably rectangular prismatic slot 100 of said movable disc 102.

[0186] Referring to a cartridge configuration say FIG. 23 for clarity; for the washing of the lever 20 the turn of stem 104 when lever handle 20 is attached to said stem portion 58 of stem 104 enables opening and closing of valves 102 and 112 and thus enables utility of the invention. The washing of the lever 20 of the invention is enabled when said lever arm 20 is attached to stem region 58 of said stem 104 and said lever 20 is initiated to rotate through a maximum predetermined angle that is greater than the angle turned to enable said lever 20 to intercept the said line of flow 777 from spout 10. The initial maximum predetermined turn of the stem 104 by lever 20 from an off mode of the cartridge 420 will be shown to reduce flow rate through spout 10 to enable spreading of detergent over ones hand with the option for washing of hands; a subsequent counter turn of said lever 20 through a predetermined angle enables increase in the flow rate through spout 10 for washing of hands using a greater flow rate; a subsequent counter turn through a predetermined angle enables said lever 20 to intercept line of flow 22 from spout 10 and also increases flow rate through spout 10 to its predesigned maximum thus enabling the choice of washing of said lever 20 and further washing of hands. A subsequent counter turn of said lever 20 through a predetermined angle enable repositioning of lever arm 20 back to a rest positioning in which flow of liquid is disabled. The reduction in flow rate of solvent through spout 10 thus enables significant conservation in the use of water as a solvent and the washing of said lever 20 significantly reduces the spread of pathogens thus enhancing health and safety.

[0187] Referring to FIG. 16 said stationary disk 112 is enabled with preferably diametric paired extension 118 for locking said stationary disc 112 within the interior passage 68 of the cartridge body 90; thus, enabling reliability and stability of said cartridge unit 420. As shown in FIG. 18, said means for locking said stationary disc 112 may be achieved when inclusion is designed within the interior passage 68 of said body 90 and were said inclusions in the passage 68 of said body 90 are dimensioned to accommodate and fit said diametric extensions 118 of said stationary disc 112. Said stationary disc 112 interfaces with the moveable disc 102 located in the passage 68 of the cartridge body 90 and with conduit 70 where preferably openings 114 in said stationary disc 112 accommodate flow to the receiving are 110 of moveable disc 102 and then through side openings 82 to the exterior of body 90 of cartridge unit 420.

[0188] Referring to FIG. 25 said conduit 70 is external to said interior passage 68, thus, to ensure reliability of the cartridge unit an elastomeric seal 88 is introduced to interface said stationary disc 112 and said conduit 70 in region 132 of the cartridge body 90. Said sealing ring 88 included within component 132 functions to apply pressure between 132 stationary valve member 112, and moveable valve member 102. The pressure exerted by said scaling ring 88 ensures optimal functioning of the cartridge for the flow of liquid. The stationary disc 112 is also enabled with a pit like lubricant containing feature 115; lubricant in said pit like feature 115 function to for ensure substantially frictionless movement of said moveable disc 102 over the surface of fixed disc 112 and also to prolong the functional integrity of the cartridge unit 420.

[0189] Referring to FIG. 26; what is shown is an explosion of the order of contiguous assembly of the position of tabs 118, the orientation of the moveable disk 102 and the orientation stationary disk 112 and a cross-section through the lower part 132 of the said cartridge body 90 when the faucet system shown in FIG. 1 is in the off mode but disposed to enable flow of liquid to said faucet when activated. Referring to FIG. 27 in contrast to FIG. 26, what is shown is an integration and relative contiguous orientation of said moveable disk 102 and said stationary disk 112 in the passage 68 of the lower part 132 of said body 90 when the faucet system of FIG. 1 is in the off mode but disposed to enable flow of liquid to said faucet when activated.

[0190] Referring to 28; what is shown is an explosion of the order of contiguous assembly of the position of tabs 118, the orientation of the moveable disk 102, the orientation of stationary disk 112 and a cross-section through the lower part 132 of the said cartridge body 90 when the faucet system shown in FIG. 1 is in the activated mode but disposed to enable substantial flow of liquid through spout 10 when said lever 20 does not intercept the line of flow 777 from spout 10 to a wash basin. Referring to FIG. 29 in contrast to FIG. 28, what is shown is an integration and relative contiguous orientation of said moveable disk 102 and said stationary disk 112 in the passage 68 of the lower part 132 of said body 90 when the faucet system of FIG. 1 is in the activated mode but disposed to enable substantial flow of liquid through spout 10.

[0191] Referring to 30, what is shown is an integration and relative contiguous orientation of said moveable disk 102 and said stationary disk 112 in the passage 68 of the lower part 132 of said body 90 when the faucet system of FIG. 1 is in the activated mode but disposed to reduce flow of liquid through spout 10 where said reduction in flow rate of liquid conserves water as a solvent when hands are being soaped.

[0192] Referring to FIG. 31; what is shown is the order of contiguous assembly and relative orientation of the handle 20, the orientation of the moveable disc 102 and the orientation of the stationary disk 112 when faucet system is in the off mode and liquid flow is disabled through spout 10 of faucet assembly for a right hand side position of faucet cartridge 420.

[0193] Referring to FIG. 32, moveable disc 102 is shown with a line of symmetry 1020 for said moveable disc 102; now referring to 1020 of FIG. 31 and consistent with the properties of a rigid body, said 1020 characterizes initial orientation of said line of axis of symmetry 1020 for 102 of FIG. 31 and transformation of said axis of symmetry 1020 in 102 in FIG. 32 subsequent to lever 20 executing its predetermined angle of rotation; thus indicating a sense and angle of rotation of moveable disc 102 from the inactive mode to the utility mode of configuration where said lever arm 20 is not disposed to intercept line of flow 22 from portion 8 of spout 10.

[0194] Referring to FIG. 33 the predetermined maximum turn of moveable disc 102 is shown with a line of symmetry 1020 for said moveable disc 102; now referring to 1020 of FIG. 32 and consistent with the properties of a rigid body, said 1020 characterizes initial orientation of said line of axis of symmetry 1020 for 102 of FIG. 32 and transformation of said axis of symmetry 1020 in 102 in FIG. 33 subsequent to lever 20 executing its predetermined maximum angle of rotation; thus when the cartridge system 604 exists in this mode the flow rate of solvent say water is significantly reduced for enabling soaping of hands and thus as mentioned enabling economic utilization of water and by extension economic, environmental and health conservation because the lever is now washed by hands that have been washed before the cartridge system is returned to its inactive mode by the turning of said lever 20 and thus also mitigating the spread of pathogens. The washing of lever 20 is enabled when said lever 20 is counter turned to intercept the line of flow 22 of liquid from spout 10 thus said lever 20 is disabled from the line of flow of solvent from spout 10 when hands are being washed.

[0195] Referring to FIG. 34, FIG. 35 and FIG. 36 what is shown is a configuration of FIG. 31 FIG. 32 and FIG. 33 for an embodiment of the invention in which the said cartridge valve 420 is configured for activation by turning a lever counterclockwise for said systems activation. Such a system is a configuration in which the cartridge unit is left side of the base of a faucet basin and more suited for a left-handed person.

[0196] Referring to FIG. 37, what is shown is an embodiment of a right-hand side cartridge valve 420 in the inactive mode were said member 65 attached to said stem 104 would abut stop member 60 to effect closing of openings 114 of stationary disc 112.

[0197] Referring to FIG. 38 what is shown is an embodiment of a right hand side cartridge valve 420 in the active mode and where rotation of the stem 104 through a maximum predetermined angle from the off configuration of the cartridge 420 would have been limited by stop member 61 when said member 65 of said stem 104 intercepts body stop member 61.

[0198] Referring to FIG. 39, what is shown is an embodiment of the crank attachment component unit 410. FIG. 40 shows an embodiment of the cartridge unit 420, bonnet nut 205 is not shown.

FIG. 43 shows a substantially symmetric section in a vertical plane of an embodiment of a detergent reservoir unit 450. FIG. 44 shows an integration of components units 410, 420, 430, 440 and 450.

[0199] Referring to FIG. 45, crank component unit 410 shows a crank region 460 with a connecting rod 496. Said crank unit 410 has a cylindrically inner grooved attachment region 462. Said inner grooved attachment 462 locks to region 52 of the upper stem portion 57 of stem 104 in a complete unit for the invention such that rotation of stem 104 substantially simultaneously rotates said crank component unit 410. Said crank unit component 410 is preferably made from non-corrosive metal such as copper, brass in order to ensure maximum and prolonged functional reliability.

[0200] Referring to FIG. 46, what is shown is an integration of said crank attachment component unit 410 to portion 52 of upper portion 57 for the said stem unit 104 of cartridge unit 420. Said crank component unit 410, said lever 20 and said upper portion 57 constitute a rigid body thus consistent with the properties of a rigid body said crank 460 will rotate consistent with the sense of clockwise or counterclockwise rotation of said lever 20 and additionally said crank 460 rotation occurs with substantially relative invariance in angular configuration relative to said lever 20. The vertex of the angle characterizing said angular separation lies on a common axis of rotation of said stem 104 and said lever 20 consequently, enabling substantial invariance in a predetermined said angular separation of said crank component 460 and said lever 20 when said crank 460 and said lever 20 are attached to said stem 104. Said crank 460 is thus substantially constrained to move in a plane. Additionally, said crank 460 and said lever 20 are disposed to be separately mated to said upper stem portion 57 by groove fit thus enabling case of manipulation in positional variation in said angle of separation between said lever 20 and said crank 460.

[0201] Additionally, a connecting rod 496, freely hinged to said crank 460 enables translation of a piston 491 when said connecting rod 496 is attached to a piston 491 thus enabling said piston 491 to activate opening and closing of valves to enable dispensing of liquid detergent from a detergent activation unit 430. Said another way, the connecting rod 496 and the crank 460 form a two-bar linkage. Furthermore, the function of said crank 460 and said connecting rod 496 is enabled on multiple angular position on said stem 104 and so enables convenient positioning of the detergent activation unit for initiating dispensing of liquid detergent by the action of said crank 460. A detergent dispensing system can therefore be conveniently positioned on a faucet mounting base for interacting within an annulus for the crank unit 410. FIG. 46 functions to show a positioning of the crank unit 410 relative to the lever assembly 304; in an assembly of the invention the positioning of the bonnet nut 205 would precede the positioning of the crank unit 410 to be followed by the positioning of the lever unit 305.

[0202] Referring to FIG. 47, what is shown is an integration of crank unit component 410 and lever unit 304 to said upper portion 57 of stem unit 104 of cartridge unit 420; thus as stated said integration of crank unit 410 and lever 20 to said upper portion 57 substantially constitutes a rigid body, consequently initiation of rotation of lever 20 initiates rotation of stem 104 and thus rotation of crank unit 410. FIG. 47 functions to show the positioning of the crank unit 410 relative to the lever assembly 304.

It will be shown that said diametric slots function to substantially resist rotation of a piston unit 449 when diametrically paired flanges 495 are enabled on said piston 491 such that said piston 491 is forced by said flanges to translate in said slots 492. Said diametrically paired slots 492 of cylindrically disposed 464 do not extend to regions of said cylinder 464 were said slots 492 would impinge the function of o-rings 489 and 490. Sealing rings 489 and 490 are enabled with access within regions defined by line 520 and line 530 of the interior wall of said cylindrically disposed 464.

[0212] Referring to FIG. 49, said cylindrically disposed component 464 is enabled with a detergent containment region 487. In a functioning unit of the invention liquid detergent is enabled to enter said detergent region 487 after detergent fluid in said region 487 has been substantially expelled. The interior wall of region 487 of cylindrically disposed 464 is enabled with a circular flange 477. It will be shown that said circular flange 477 function to contain an outlet valve unit 482.

[0213] Referring to FIG. 51, what is shown is an embodiment of a planar cross-section of the detergent activation unit 430. Said detergent activation system 430 comprises a stabilizing encasement component 498 which has already been described, an outlet valve component unit 484 shown in FIG. 53 and a piston component unit 449 shown in FIG. 57. Said piston component 449 is preferably configured from Bakelite, melamine or nylon.

[0214] Referring to FIG. 53, what is shown is an embodiment of the detergent outlet unit 484. FIG. 54, FIG. 55 and FIG. 56, show an embodiment of the individual members of said detergent outlet 484. Referring to FIG. 54, what is shown is an embodiment of an end cap component 475 of said detergent outlet unit 484. Said component 475 is disposed to be characterized as a solid cylinder portion 471 contiguous with a an outer spirally grooved cylindrical annulus 474 to enable spiral insertion in compatible grooved region 468 of said cylindrical disposed 464. Said outer spirally grooved component 474 is of a lesser radius than cylindrically disposed component 471. An outer grooved preferably solid cylindrical region 473 of a lesser radius than 474 is contiguous with a circular face member 471 but non-contiguously included by cylindrically shaped annulus 474. Referring to FIG. 55, what is shown is a spring 483 dimensioned to be spiraled within the grooves 472 of 473 thus enabling one end of said spring 483 to be fixed when said 475 is attached in region 468 of cylindrical disposed 464. Components 471, 474 and 473 are disposed to be geometrically concentric. Referring to FIG. 56, component 470 characterizes cylindrically disposed contiguously concentric with a lesser radius cylindrically disposed region 476. Said cylindrically disposed region 476 is spirally grooved to be compatible with spring member 483. Said grooved member 476 functions to stabilize said spring 483 and preferably fully enshrouds said member 485. When said 475, 483 and 470 are integrated in a functioning unit of the invention the sum total of the cylindrical heights of cylinder 473 and the height of cylinder 476 is less than that of the relaxed length of spring 483 thus enabling a compressive length of said spring 483. It will be shown that the compressive length of said spring 483 is predetermined to be greater than the maximum translation of a piston unit 449 when said invention functions according to design. Said outlet valve 484 components may preferably configured from Bakelite, melamine or nylon while the spring unit 483 is preferably made from stainless steel for resistance to the humid environment of a faucet.

[0216] Referring to FIG. 57, contiguous and concentric to said cylindrically disposed 491 and in region 487 of said cylindrically disposed 464 is component 486. Said component 486 is of a lesser radius in comparison to the radius of 491. Said reduced radius component 486 functions to enable detergent liquid availability in said region 487 and also to initiate dispensing of fluid detergent from said region 487. It will be shown that said reduced radius of 486 in comparison to the radius of member 491 functions as a leading edge of the piston unit 449 for initiating contact with 482 of outlet valve unit 484 to enable detergent liquid dispensing through outlet 478 and for replenishing region 487 of 498 with detergent fluid in said region 487. Contiguous with said component 491 and in region 466 of cylindrically disposed 464 are flange component 493 and flange component 494. Said flanges 493 and 494 are enabled with access slots 454 and 455. Said access slots 454 and 455 enable hinged connection of piston unit 449 to connecting rod 496.

[0217] Referring to FIG. 57, said piston component 449 is diametrically enabled with raised flanges 495. Said diametrically paired flanges are preferably vertically disposed and positioned in diametric access slots 492 in region 466 of said cylinder 464. Said diametrically paired flanges are predetermined to function within the limits of paired access slots 492. Said diametrically paired flanges 495 function to resist rotation in the movement of piston unit 449 and thus substantially restrict the motion of piston unit 449 to translation. Additionally, said diametric flanges 495 enable piston component to stay within the influence of sealing ring 489 and sealing ring 490.

Said containment 624 is externally spirally grooved for insertion connection in the conduit component 724 of an internally grooved detergent conduit depicted in FIG. 71. Said region of 624 distal to region 626 flares conically to reservoir region 487 of said cylinder 464.

[0222] Referring to component 681 shown in FIG. 64, what is shown is an annulus shaped component 623 were said component 623 is spirally grooved on its outer curved surface. Said component 623 is concentrically enabled with a circular access opening 622 were said access opening 622 functions as a conduit for detergent fluid. Contiguous and concentric to component 623 is component 625 were said component 625 is an annulus shaped. The radius of said component 625 is less than the radius of component 623 but greater than the radius of component access conduit opening 622. Said component 625 functions as a guide for spring component 621.

[0223] Referring to component 682 depicted in FIG. 64 said component 682 is disposed to be a composite shape characterized as a solid truncated cone 634 contiguous with a preferably solid cylindrical section 627 where the larger base radius of said solid truncated cone 634 is common to the radius of said cylinder 627. Said preferably solid cylinder 627 is concentrically contiguous with a circular face of an alternate cylinder 631 where said cylinder 631 is enabled with a larger radius than that of said cylinder 627. Said cylinder 631 alternate circular face is further enabled concentrically with an alternate solid cylinder 638 were said alternate solid cylinder 638 is internally spirally grooved for insertion of externally spirally grooved extension 639 of component 632 depicted in FIG. 64. Said externally grooved extension 639 is contiguous with said 632. Said component 632 is disposed to be characterize as a cylinder enabled with a partial spherical component where said cylindrical section is internally spirally grooved. Said cylindrical component 631 is further enabled with conduit channels 628 extending from a circular face of said cylinder 631 to the alternate face of said cylinder 631. Said channels 628 enable the flow of detergent to said region 487 of detergent activation unit 430.

[0224] FIG. 66 shows a relative upward looking view of 681 through a horizontal plane at right angles to the height of cylindrical annulus 625 where said plane contains the line 700 of FIG. 64. FIG. 67 shows a depressive view of 682 through a horizontal plane containing line 702 and where that plane is parallel to a circular face of cylinder 631.

Said shoulder functions as a support base for component 631.

[0225] Referring to FIG. 71; what is shown is an embodiment of the detergent component containment unit 450. Said detergent containment unit is enabled with a preferably cylindrical detergent reservoir 716 with means 726 for enabling flow or disabling flow of detergent from said detergent reservoir 716. Component 712 of said detergent reservoir functions as a spirally grooved cap. Removal of said spirally grooved cap 712 enables refilling of said detergent containment reservoir. Said detergent containment reservoir is also enabled with an opening 714. Said opening 714 functions to enable detergent fluid to enter region 487 of 464 when motion of said piston 491 enables a pressure difference between said region 487 and atmospheric pressure in said detergent containment reservoir 716 and said opening 714 enables pressure in said containment reservoir 716 to be that of the atmosphere. Said detergent reservoir 450 is preferably made from polypropylene, polystyrene, polycarbonate plastic or allied compatible transparent or see through recyclable plastic. Transparency or seeing through reservoir better enable management of detergent solution for timely refilling or replacement of said detergent reservoir 450. Due to anticipated multiple interventions of the reservoir 450 for refilling or replacement a recyclable material for the reservoir 450 is preferred thus enabling environmental, energy and material conservation.

[0226] Referring to FIG. 71, said detergent containment unit is enabled with a preferably cylindrical conduit 722 were said conduit 722 is preferably of a lesser radius than 716 but contiguous with detergent containment reservoir 716. Said conduit is enabled with a thicker wall cylindrical region 720 where the central concentric opening or internal channel 718 is of a lesser radius than the radius of said cylindrical disposed component 722.

[0227] Referring to FIG. 71, the lower region of said 722 is internally spirally grooved for accommodating inclusion of valve component 440 shown in FIG. 62. Referring to FIG. 72 what is shown is a section of an inclusion 732 enabled in said annulus region 720 were said inclusion 732 is configured to accommodate component 726 thus enabling said 726 to initiate enabling or disabling flow of detergent from said containment reservoir 716. Said component 726 may be configured from Bakelite, melamine, nylon or other appropriate compatible material.

[0228] Referring to FIG. 73, what is shown is component 726. Said component 726 is disposed to be characterize as a solid truncated cone 721 contiguous with a rectangular prism 727 were said rectangular prism 727 functions as a lever for initiating motion of said truncated cone 721. Said truncated cone 721 is enabled with a conduit 728 where said conduit is enabled with diametric openings on the curved surface of said truncated cone 721.

[0229] Referring to FIG. 74 what is shown is a top view of an embodiment of the containment reservoir 716. Referring to FIG. 75 what is shown is an orientation of said component 726 in region 732 of 720 when said component 726 disables the flow of detergent from containment reservoir 716. Said conduit 718 is then substantially perpendicular aligned to said conduit 728 such that the flow of detergent fluid is disabled from detergent from containment reservoir 716. Referring to FIG. 76 what is shown is an orientation of said component 726 in region 732 when said component 726 enables the flow of detergent from containment reservoir 716 of detergent containment reservoir 716. Said conduit 718 is then substantially parallel aligned to with conduit 728 such that the flow of detergent fluid is enabled from containment reservoir 716.

[0230] Referring FIG. 77, a clockwise sense of rotation of said lever 20 for the invention will now be enacted. A counterclockwise sense of rotation of lever 20 is a mirrored action for a clockwise sense of rotation. A description for the function of the entity is for an embodiment in which detergent is expelled substantially at about the same time that water is enabled to flow through spout 10 for the washing of hands thus a coordination between the translation of the piston substantially parallel to the axis of cylindrically disposed 464. The compressive length of spring 483, the radius of the crank 460, the travel of valve 482 prior to expulsion of detergent, the retraction of the connecting rod 496 prior to completion of the maximum predetermined angle of rotation of lever 20 are enabled and dimensioned within the maximum predetermined angle of rotation of lever 20 with the radius of the crank 460. An embodiment of the invention in which the leading edge 486 of piston 491 is substantially close to outlet valve 482 in the inactive state is preferred for timely dispensing of detergent. The washing of the lever 20 is preferably enabled on the counter rotation of said lever 20 and subsequent to the completion of the maximum predetermined angle of rotation of said lever 20 when the crank would have retreated while the lever 20 was being turned from the off position to its maximum predetermined angle of rotation. The vertical line of flow of water from spout 10 is not intercepted by lever 20 when stops 60 and 61 restrict said lever 20 to its predetermined maximum angle of rotation. Thus, as can be seen the utility of the invention disposes the use of the invention to just washing hands with detergent prior to maximum predetermined rotation of said lever 20 when water flows through spout 10 followed by a choice to wash said lever subsequent to completion of the maximum predetermined rotation of lever 20. Consequently, when moveable disc 102 and stationary disc 112 are configured for maximum opening of 114 for a turn of 90 degrees then a predetermined maximum angle of rotation of lever 20 is greater than 90 degrees thus stops 60 and 61 are not solely disposed to being diametrically opposite for a 90 degree orientation of lever 20 and spout 10.

[0231] Referring to FIG. 77 what is shown is a sectional view through a vertical plane of an assembled configuration of said crank component unit 410 shown in FIG. 39, wherein said cartridge component 420 shown in FIG. 40, said detergent activation unit shown in FIG. 41, said inlet valve component unit shown in FIG. 42, and said detergent containment unit 450 shown in FIG. 43 are depicted when said configuration depicted in FIG. 77 exists in an inactive configuration.

[0232] Referring to FIG. 78 what is shown is a section in a horizontal plane of the detergent activation unit 430 in association with the stem 104 and crank unit 410 of FIG. 77.

[0233] Referring to FIG. 77 the component 486 of piston component 491 is constrained to be in substantial proximity to valve component 482 thus spring component 483 exists in its relaxed configuration, consequently enabling closure of outlet 478 by said valve component 482. Referring to FIG. 77, said component 631 rests on shoulders 629 when the reservoir valve 632 is deactivated consequently enabling flow of detergent through conduits 628 to region 487 of 464 when said system is primed for initiation to function where such priming action constitutes a back-and-forth motion of said piston 491 to open and close valve component 632. Said back and forth motion of piston component 491 initiate opening and closing of valve 632 thus enabling a pressure difference between interior volume 716 of detergent reservoir 450 depicted in FIG. 71 and region 487 of cylinder 454 for the detergent activation unit 430 consequently enabling fluid flow of detergent to 487.

[0234] Referring to FIG. 78 what is shown is a sectional view in a horizontal plane of an integrated configuration of said crank component unit 410 shown in FIG. 39, said cartridge component 420 shown in FIG. 40, said detergent activation unit shown in FIG. 41, said inlet valve component unit shown in FIG. 42 and said detergent containment unit shown in FIG. 43 when said configuration depicted in FIG. 81 exists in an inactive configuration. Member 495 is positioned within groove 437 of crank unit 410.

[0235] Referring to FIG. 78a, what is shown is a diagrammatic representation of the inactive state of the invention. In the inactive state when a lever handle is parallel to component 496 said valve 632 is normally open while said valve 482 is normally closed. Said leading edge 486 of piston component 491 is substantially close to valve 482 and additionally, outlet spring 483 and inlet spring 621 are in a relaxed state. In FIG. 78a the leading edge 486 and valve 632 is positioned between the lines 1021 and 1022. The outlet 478 would be positioned between lines 1022 and 1023. The outlet 478 diametric dimension is less than that of the separation between lines 1022 and 1023 thus by choosing the travel of the leading edge before opening of valve 478 to be greater than the separation between lines 1021 and 1022 both valves 632 and 482 can be closed to enable build up of pressure in 487 before valve 482 opens to dispel fluid through conduit 478 while valve 632 remains closed.

[0236] It is preferred that detergent be expelled substantially at the same time as the flow of water through spout 10 or immediately prior to the commencement of water flow through spout 10. Prior expulsion of detergent is enabled when the moveable disc 102 sufficiently blocks area 114 of the stationary disc 112 to enable turning of stem 104 by the lever 20 to enable the action crank 460 and follower 496 to activate detergent expulsion prior to water flow through openings 114 of the stationary disc. Thus, geometric relation between the angular position of the crank 410 on the stem 104, the lift of said crank 410, the follower 495, the leading edge 464 and valve 482 is enabled to allow timely expulsion of detergent within the interval of turning of said lever 20.

[0237] Referring to FIG. 79 what is shown is a view of an integrated configuration of said crank unit 410 shown in FIG. 39, said cartridge component 420 shown in FIG. 40, with a sectional view of said detergent activation unit shown in FIG. 41, said inlet valve component unit shown in FIG. 42 and said detergent containment unit shown in FIG. 43. For the configuration of FIG. 79, when said lever 20 has turned clockwise at a predetermined angle the crank unit 410 is at its maximum displacement and the spring 483 exerts a maximum restoring force on the outlet valve unit 482. Additionally, said piston 491 is substantially constrained by channel 492 to only motion by translation consequently enabling predictable functioning of the invention.

[0238] Referring to FIG. 79, the rotation of lever 20 enables beveled edge 488 of said piston 491 to functions as a wedge to intercept and initiate vertical translation of valve member 632 thus dislodging inlet valve component 682 shown in FIG. 64 from its seat 629 and thus initiating distortion of spring 621 and thus enabling a restoring force on said spring 621 and consequently enabling member 632 to propagated normal force on said piston unit component 449 shown in FIG. 57.

[0239] Thus piston unit component 449 shown in FIG. 57 is acted on by an axial force by said outlet spring member 483 and a normal force by inlet spring member 621 thus when said inlet spring member 621 is enabled with a superior spring constant that opposes the influence of spring 483 on said piston unit 449 said piston unit 449 is disposed to be immobilized and consequently disabling any influence of the spring 483 on the rotation stem 104.

[0240] Additionally, vertical motion of valve member 632 further enables closure of said valve 632 thus disabling flow of liquid detergent through conduits 628 to region 487 of cylinder 464 consequently enabling build up of fluid pressure in region 487 of said cylinder 464 when said lever 20 continues to rotate and said valve member 632 continues to maintain a stress on said piston member 449 when valve 482 is still closed.

[0241] Referring to FIG. 79, said lever 20, said crank unit 460 and said stem 104 substantially function as a rigid body thus clockwise motion of lever 20 enables said crank 410 to translates piston 491 consequently enabling piston extension 486 to intercept and translate and open outlet valve 482 and thus enable ejection of detergent fluid through outlet 478.

[0242] Referring to FIG. 79, said crank 460 on its rise interval would have translated said piston extension a measure substantially that of the length of the crank 460. Thus, spring component 483 would thus have been distorted a displacement substantially that of the length of the crank 460 when said distorted displacement of said spring member 483 is allowable by the physical characteristics of said spring component 483. Said crank member 460 is thus predetermined to execute its maximum translation prior to the execution of the clockwise maximum predetermined angle of rotation of said lever 20.

[0243] At the initial turn of lever 20 when detergent has been enabled and water flows through spout 10 hands are enabled to be washed and the faucet counter turned to its off mode without enabling washing of lever 20.

[0244] Referring to FIG. 80, what is shown is a horizontal cross-section of the configuration depicted in FIG. 79.

[0245] Referring to FIG. 80a, what is shown is the closure of valve 632 and the opening of valve 482 between lines 1022 and 1023. Crank 460 now is at its maximum lift while spring 482 is now exerting a maximum restoring force simultaneously as spring 621 exerts a force on piston component 491. The lever 20 has not yet turned through its maximum predetermined angle. The geometric relation of the stationary disc 112, the moveable disc 102 and the configuration of lever 20 relative to fixed stops 60 and 61 were said fixed stops 60 and 61 are positioned on the upper surface 130 is shown in FIG. 25.

[0246] Referring to FIG. 81, what is depicted is a configuration wherein said lever 20 has executed its clockwise maximum predetermined angle of rotation and said lever 20 is deterred from further rotation by said limiting cartridge body stop. Said connecting rod 496 would have retreated with reduced influence of spring 483 with maximum influence of spring 621 on piston 491 with further rotation restricted by body stop 61 and the force of spring 621 acting on piston 491 thus solvent such as water is enabled to flow without interruption when the invention is being utilized. Valves 632 and 483 are both closed for the configuration of FIG. 81.

[0247] Referring to FIG. 82, what is depicted is a top view configuration of the configuration shown in FIG. 81.

[0248] Referring to FIG. 82a what is shown is a diagrammatic representation in the active state when the lever 20 has been turned through its maximum predetermined angle of turn and the leading edge 464 has retreated from the valve 482 while being acted on by a reduced axial force by spring 483.

[0249] Referring to FIG. 82a, the crank 460 has also now retreated and the choice of the dimension of the cross section of outlet conduit 478 and the separation between line 1022 and line 1023 has enabled the closure of valves 482 and valve 632. The combined force of action by spring 621 on the piston 491 and the reduction of the force of spring 482 coupled with the off set in combination with the action of stop member 61 immobilizes the lever at it maximum predetermined angle of rotation thus water or any other solvent is enabled to flow the spout 10 without interruption for the washing of hands.

[0250] A counter turn of lever 20 enables said lever 20 to intercept the line of flow 777 from said spout 10 thus enabling washing of the lever and further washing of hands. Further counter turn of said lever to its rest position enables refilling of said region 487 of cylinder 464 in preparation for the utility of the invention.

[0251] Referring to FIG. 82b what is shown is a section in comparison to FIG. 82a that includes outlet 478. When crank 460 retracts at the turning of lever 20 to its maximum predetermined angle outlet 478 is enabled between region 1023 and 1024 thus enabling valve 632 and valve 482 to be in closure mode thus minimizing dripping or leakage.

[0252] When said system depicted in FIG. 81 is being deactivated after use said lever 20 is rotated counter clockwise thus enabling closure of valve 482 while said valve component 632 opens, thus further counter clockwise rotation of lever 20 enables a pressure difference in region 487 and thus enables flow of detergent in said region 487 when said valve member 482 is enabled to be closed prior to the opening of valve 632. Said system is now in a state for its next utility function.

[0253] The detergent activating unit 430 is disposed to be positioned within a circle of influence with the detergent activation unit 430, thus enabling flexibility in the positioning of said detergent activation unit 430 on a faucet mount. Additionally multiple configurations are enabled for timely dispensing of fluid while lever 20 is being rotated.

[0254] Referring to FIG. 83 what is shown is a vertical section in a plane symmetric to the detergent activation unit and the detergent reservoir in relation to the position of the crank unit 410, the cartridge unit and the lever unit in the inactive or closed mode of the invention.

[0255] Referring to FIG. 84, what is shown is a configuration of the lever, the movable disc 102 and the fixed disc for the closed mode for FIG. 83.

[0256] Referring to FIG. 85 what is shown is a vertical section in a plane symmetric to the detergent activation unit and the detergent reservoir in relation to the position of the crank unit 410, the cartridge unit and the lever unit in the active or open mode of the invention.

[0257] Referring to FIG. 86, what is shown is a configuration of the lever, the moveable disc 102 and the fixed disc in the open mode for FIG. 85.

[0258] Referring to FIG. 87 what is shown is a sectional configuration of a substantial cylindrically disposed cartridge mount 820 enabled with slots 821 for mounting the cartridge unit 420. Said member 820 functions to laterally encloses cartridge unit 420 with space between the inner wall of 820 and the outer wall of cartridge body 90 for the cartridge unit 420. Said member 820 also functions to arrest rotary motion of said cartridge body 90 when said cartridge body 90 is associated with said cartridge mount 820 and said tabs 128 of said cartridge body 90 are recessed in symmetrically arranged slots 821 on the perimeter region 819 of said member 820. In an assembled unit of the invention cartridge valve unit 420 is stabilized in region 801 of said cartridge mount 820 when flanges 128 of said cartridge body 130 are recessed in slots 821 of said cartridge mount 820.

[0259] Referring to FIG. 87, said cylindrically disposed member 820 is configured with a grooved upper end 819 with a smaller diameter for accepting bonnet nut 205.
