A lever is journalled for rotation in the sealing member and has an end thereof interconnected with the control member. Means are provided for limiting the movement of the lever to a reciprocating motion in a single plane at an angle to the flat surface of the chamber.
This application is a continuation-in-part of my copending application Ser. No. 456,311, filed May 17, 1965, now abandoned.
Among the objects of this invention are to provide a single handle faucet valve that efiiciently controls the mixing of hot and cold water; which is relatively low in cost; which is relatively free of maintenance; which is lightweight; and which can be readily assembled and disassembled for service.

FIG. 8 is a fragmentary sectional view taken along the line 88 in FIG. 7.
FIG. 9 is a fragmentary sectional view taken along the line 99 in FIG. 7.
FIGS. 10 and 11 are partly diagrammatic views showing the relative positions of the parts in different positions of the valve.
Referring to FIG. 1, the faucet valve embodying the invention is adapted to be used with various spout arrangements including the type shown in FIG. 1 wherein a spout 10 has a cylinder or sleeve 11 whereby it is rotatably mounted on the single handle faucet.
As shown in FIG. 2, the single handle faucet valve comprises a body 13 that is formed with a cylindrical chamber or opening 14 that opens upwardly through the upper end of the body. The bottom surface 15 of the chamber 14 is substantially fiat and inlet passages 16, 17 extend upwardly from the bottom of the body 13 through the surface 15. Hot and cold water, respectively, are adapted to be supplied to the passages 16, 17 through inlet pipes 18, 19 that are swaged or otherwise provided in the openings.
A scaling disc 20 which is preferably made of a low friction plastic material that is rigid, non-deformable and resistant to hot water, such as Delrin, is provided in the chamber 14. Sealing disc 20 is formed with a substantially fiat bottom surface 21 that engages the flat surface 15 of chamber 14. The disc is provided with circular openings 22, 23 that are adapted to be moved into registry with the upper ends of the openings 16, 17 as shown in FIG. 4 or out of registry as shown in dotted lines in FIG. 4.
A sealing member 25 is provided in the upper end of chamber 14 and has a peripheral circular groove 26 in which an O-ring 27 of resilient material such as synthetic rubber is provided to form a seal with the wall of the chamber 14. The upper end of the sealing member 25 is provided with a radial projection 28 that extends into a depression 29 in the body 13 and thereby prevents rotation of the sealing member 25. A head 30 is threaded on the upper end of the body 13 and has a surface 31 that engages the upper end of the sealing member 25 to retain the sealing member into position.
As further shown in FIG. 2, the underside 32 of the sealing member 25 is substantially fiat and engages an O-ring 33 provided in a groove 34 in the substantially fiat upper surface of the control disc 20. By this arrangement, the sealing member 25 yieldingly urges the control disc 20 and particularly the surface 21 of the control disc 20 into contact with the bottom surface 15 of chamber 14. A seal is thereby provided which permits water into the area 35 but prevents the flow of water beyond the O- ring 33 or the O-ring 27.
Further in accordance with the invention, the upper ends 36, 37 of the inlet passages 16, 17 are enlarged to receive an annular sealing member 38 of rubber or other suitable resilient material to provide a seal with the un dersurface 21 of the sealing member 20. In order to insure this seal, coil springs 39 are compressed between shoulders 40 and 41 of the body and shoulders on the sealing rings 38. In addition, to insure that water will not seep between the surfaces of the enlarged openings 36, 37 and the respective sealing members 38, the lower end of each sealing member 38 is substantially circular in cross section as at 42 integral with the member to provide a secondary seal in the nature of an O-ring seal.
As shown in FIG. 2, a lever 45 in the form of a cylindrical stem is journalled in the sealing member 25 by a ball 46 that is preferably made of plastic, such as Delrin, and seats against a spherical seat 47. A passage 49 in the lower end of sealing member 25 is elongated in a single plane and has substantially the diameter of the lever 45 so that the lever can swing in only one plane but is rotatable about the axis thereof.
The lower end of the lever projects downwardly through passage 49 into the sealing member 25 and a second ball 50 is provided on the lower end of the lever and held thereon by a pin 51, the ends of which extend beyond the periphery of the ball. The ends 52 extend into vertical grooves or slots 53 and thereby interconnect the lower end of the lever with the control disc 20.
By this arrangement, swinging of the lever 45 in the single plane controlled by the slot or passage 49 causes the control disc 20 to move back and forth while rotation of the lever causes the control disc 20 to rotate in any 3 position. A control knob 54 is provided on the upper end of the lever 45.
By rotating the control knob 54, the openings 22 in the control disc can be moved from position in registry with the inlet 16, 17 as shown in FIG. 4 in solid lines to a position out of registry, thereby controlling the amount of water flowing through the inlets into the chamber or space 35.
By swinging the lever back and forth, the extent of communication or registry of the openings 22, 23 with the passages 16, 17 is controlled. By moving the lever to the left or counterclockwise as shown in FIG. 2, substantially the entire opening 22 is brought into registry with the inlet passage 16 so that only hot water will flow. By swinging the lever to the right or clockwise as shown in FIG. 2, substantially the entire opening 23 is brought into registry with the inlet passage 17 so that only cold Water will flow.
In order to limit the rotation of the control disc 20 to full-open or full-close position, the upper ball 46 has upwardly and outwardly extending cars 75 which are diametrically opposed and extend into a generally rectangular cavity 76 in the lower end of the sealing member 25 (FIG. 6). As the lever 45 is rotated, the ears 75 engage the sides of the cavity 76 to limit the rotation of the lever as shown in broken lines in FIG. 6.
As further shown in FIG. 2, the area 35 communicates through a passage 55 with an exterior annular groove 56 in the body that in turn communicates with the interior of the spout 10. A seal is provided between the cylindrical portion 11 of the spout and the outer surface of the valve body 13 by O- rings 57, 58, 59.
In accordance with well-known faucet valve construction, suitable means may be provided on the end of the spout to return the water through a tube 60 to an annular passage 61 in the body and downwardly to an outlet 62 and in turn to a rinse tube. This arrangement forms no part of the present invention.
It can thus be seen that there has been provided a faucet valve wherein a relatively limited number of parts are provided, eflicient control of hot and cold water is achieved and substantially no maintenance is required.
The various parts of the faucet valve are readily accessible by removing the head 30. In case wear or loss of resiliency occurs in the O-ring 33, a cylindrical control collar 70 is threaded into the upper end of the head 30 and is adapted to be threaded downwardly into engagement with the upper end of the control member 25 to increase the force of the control member against the O-ring 33.
As shown in FIG. 2, the disc 20 and control member 25 are preferably made of plastic material and have various portions thereof cut away as at 71, 72 to reduce to the weight.
As shown in FIG. 7, this form of the single handle faucet valve comprises a body 13' that is formed with a cylindrical chamber or opening 14' that opens upwardly through the upper end of the body. The bottom surface 15' of the chamber 14' is substantially flat and inlet passages 16, 17' extend upwardly from the bottom of the body 13 through the surface 15'. Hot and cold water, respectively, are adapted to be supplied to the passages 16', 17' through inlet pipes 18', 19 that are swaged or otherwise provided in the openings.
A sealing disc 20' which is preferably made of a low friction plastic material that is rigid, non-deformable and resistant to hot water, such as Delrin, is provided in the chamber 14'. Sealing disc 20' is formed with a substantially fiat bottom surface 21' that engages the flat surface 15' of chamber 14'. The disc is provided with D--shaped openings 22, 23' that are adapted to be moved into registry with the upper ends of the openings 16', 17'.
A sealing member 25' preferably made of the same plastic as sealing disc 20' is provided in the upper end of chamber 14 and has a peripheral circular groove 26 in which an O-ring 27' of resilient material such as synthetic rubber is provided to form a seal with the wall of the chamber 14. The upper end of the sealing member 25' is provided with radial projections 28' that extend into depressions 29' in the body 13' and thereby prevent rotation of the sealing member 25'. A head or cap 30' is threaded on the upper end of the body 13' and has a surface 31 that engages the upper end of the sealing member 25 to retain the sealing member into position.
As further shown in FIG. 7, the underside 32' of the sealing member 25' is substantially fiat and engages an O-ring 33' provided in a groove 34 in the substantially fiat upper surface of the control disc 20'. By this arrangement, the sealing member 25' urges the control disc 20' and particularly the surface 21' of the control disc 20 into contact with the bottom surface 15' of chamber 14'. A seal is thereby provided which permits water into the area 35' but prevents the flow of water beyond the O- ring 33' or the O-ring 27'.
Further in accordance with the invention, the upper ends 36', 37' of the inlet passages 16, 17 are enlarged to receive an annular sealing member 38' of rubber or other suitable resilient material to provide a seal with the undersurface 21' of the sealing member 20. In order to insure this seal, coil springs 39 are compressed between shoulders 40' and 41 of the body and shoulders on the sealing rings 38'. In addition, to insure that water will not seep between the surfaces of the enlarged openings 36', 37' and the respective sealing members 38'. the lower end of each sealing member 38' is substantially circular in cross section as at 42' integral with the member to provide a secondary seal in the nature of an O-ring seal.
As shown in FIG. 7, a lever 45' in the form of a cylindrical stem is journalled in the sealing member 25' by a collar 46' which has a spherical seat 46a engaging an upwardly extending spherical projection 47' on the sealing member 25'. The cross sectional configuration of the complementary portions of the collar 46' and lever 45' is D-shaped so that they are non-rotatable relative to one another. The passage in the projection 47' through which the lever extends is elongated in a single plane and has substantially the diameter of the lever 45 so that the lever is free to swing in only one plane but is rotatable about the axis thereof.
The lower end of the lever projects downwardly through passage 49 into the sealing member 25' and a ball 50' is provided on the lower end of the lever and held thereon by a pin 51', the ends 52' of which extend beyond the periphery of the ball 50 into vertical grooves or slots 53' and thereby interconnect the lower end of the lever with the control disc 20'.
By this arrangement, swinging of the lever 45' in the single plane controlled by the slot or passage 49' causes the control disc 20 to move back and forth while rotation of the lever causes the control disc 20 to rotate. A control knob 54' is provided on the upper end of the lever 45'.
By rotating the control knob 54', the openings 22' in the control disc can be moved from position in registry with the inlet 16, 17' as shown in FIG. 7 in solid lines to a position out of registry, thereby controlling the amount of water flowing through the inlets into the chamber or space 35.
By swinging the lever back and forth, the extent of communication or registry of the openings 22, 23 with the passages 16', 17' is controlled. By moving the lever to the left or counterclockwise as shown in FIG. 7, substantially the entire opening 22' is brought into registry with the inlet passage 16' so that only hot water will flow (FIG. 11). By swinging the lever to the right or clockwise as shown in FIG. 7, substantially the entire opening 23' is brought into registry with the inlet passage 17' so that only cold water will flow (FIG. 10).
In order to limit the rotation of the control disc 20' to full-open or full-close position, the collar 46 is formed with diametrically extending ears which are adapted to extend into engagement with generally flat side walls 76' in the upper end of the sealing member 25' (FIG. 8). As the lever 45 is rotated, the cars 75' engage the sides of the cavity 76 to limit the rotation of the lever, The diameter of the collar 46 in the vicinity of the walls 76' is substantially equal to the distance between the walls 76'.
As further shown in FIG. 7, the area 35' communicates through a passage 55' 'with an exterior annular groove 56 in the body that in turn communicates with the interior of the spout A seal is provided between the cylindrical portion 11' of the spout and the outer surface of the valve body 13' by O-rings 57', 58', 59'.
In accordance with well-known faucet valve construction, suitable means may be provided on the end of the spout 10 to return the water through a tube 60' to an annular passage 61' in the body and downwardly to an outlet 62' and in turn to a rinse tube. This arrangement forms no part of the present invention.
It can thus be seen that the form of the invention shown in FIGS. 7-12 differs from the form of the invention shown in FIGS. 1-6 in (l) the reversal of the socket and ball connection between the lever and sealing member, (2) the provision of the limitation of the rotation of the lever as being in the upper end of the sealing member rather than the lower end of the sealing member, (3) the elimination of the control collar 70 and (4) the changing of the openings in the valve member from a circular to a D-shaped configuration.
In each form of the invention, the faucet can be turned on or off without affecting the degree of registry of the control disc with the inlet passages.
Specifically, at any angular position of the handle, representing a specific water setting of either hot, cold or mixed hot and cold, the handle can be rotated to and from on and off" position without affecting the water setting. In addition, the water setting can be made before the knob is rotated to on position.
