Specification of Letters Patent.
Patented Aug 19,1913.
Application filed m a, 1912. Serial No. 708,004.
To all whom it may concern:
Be it known that I, THOMAS F. PAYNE, a citizen of the United States of America, re siding at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Valves, of which the following is a full, clear, and exact description, reference bein had to the accompanying drawings, whic form, part of this specification This invention relates to valves and has particular reference to faucets or bibs.
It contemplates the provision of a valve which is easy to operate, simple and compact in construction and which may be readily taken apart and assembled.
In the accompanying drawings I have shown a sink bib or valve embodying my invention, vention is not limited to this particular device, and, without the necessity of specific illustration, may be embodied in other forms of faucets and valves.
Figure 1 is a vertical sectional view through a valve embodying my invention, the valve being in closed position; Fig. 2 is a similar view showing the valve in an open position; Fig. 3 is a section on the line 3-3 of Fig. 2; and Fig. 4: isa side elevation'of the cam-sleeve to be hereinafter more fully described.
The casing 2 of the valve has the inlet 3 which may be connected by means of the nipple or stub cylinder 4 to the source of supply. The mouth of the faucet or outlet 5 leads from the chamber 6 within the cas-- ing, between which chamber and the inlet 3 is the horiiontal wall portion 7 formed in which is the intermediate port 8 surrounded by a suitable valve seat 9. Co-acting with the valve seat 9 for opening and closing of port 8 is the valve 10 mounted on the lower terminal of the-stem 11 which extends up through the cap 12 threaded on the upper barrel 13 of the casing. Surrounding the stem 11 is a sleeve 14: which has an outer flange or lug 15 which is dis osed to lie interposed between the top 0 the barrel 13 and a clamping shoulder of the ca 12. Suitable packing 16 lies between the ange 15 and the top of the valve casing so as to seal the valve at this point, and carried by the sleeve 14 in the annular recess 17 is suitable packing 18 which is kept in position by the annulus 19. Interposed between the member 19 and the head of the valve 10 is but it will be premised that the in the coil spring 20 whichserves to normally keep the valve in closed position on its seat. The upper portion of the sleeve member 14 is formed into preferably two symmetrically disposed angular cam faces 21 in cooperative association with which are two oppositely disposed rollers 22 carried by the stem 11, for opening and closing of the valve when the stem is caused to be rotated by a suitable hand piece or handle 23. As shown in Fig. 3, to prevent rotation of the sleeve 14 within the casing when the valve stem is rotated, the casing and the member 14; have the opposing fiat faces 24.
Thevalve 10-preferably comprises a cap 25 fastened to the stem by screw threads-2'6. Within this capv 25 is the valve packing 27 which is held in position by the screw threaded flanged ring 28, as clearly shown} By referring to Figs. 1 and 2 it will be seen that rotation of the valve stem' will' cause the rollers 22 to ride upwardly on the cam faces 21, thereby opening the valve. As soon as the pressure is released the spring 20 will cause the valve to return to its seat. The broad idea of employing co-actingcams and rollers to cause reciprocation of the valve stem, is, ofcourse, not new in the art. However, it has been found that this form of valve action readily binds or sticks in an objectionable manner and that such sticking or binding isusually brought about by friction between the rollers and cam faces. I overcome this result by forming the rollers preferably slightly conical and also by angularly sloping the upper faces of the cam projections in a downward manner toward the stem with the result that only a narrow surface of the rollers is utilized and furthermore the angular shape of the cam tends to prevent the rollers from working outwardly toward the casing and binding thereagainst as is commonl the case.
The a vantages of my invention will be found to reside not only in the non-sticking valve but also in the construction of a valve in which leakage is prevented, and which may be readily taken apart and assembled.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. In a faucet valve, a casing having an inlet and a discharge outlet, and an intermediate port, a valve controlling the port, a stem carried thereby, rollers mounted on the stem, a sleeve portion fitting in the casing and having upwardly extending oppositely disposed cam projections with which the roll ers are adapted to co-act to shift the valve, a
screw cap for holding the sleeve in position,
packing between said stem and sleeve, a packing retaining ring, and a spring interposed between the retaining ring and the valve.
2. In a faucet valve, a casing having an inlet and a discharge outlet, and an intermedisposed cam project-ions with which the .rollers are adapted to co-act to shift the valve, a screw cap for holding the sleeve in position, packing disposed in the lower end of said sleeve and surrounding the stem, a follower-like retaining ring associated with the sleeve, and a spring interposed between the retaining ring and the valve.
In testimony whereof, I have hereunto set my hand in the presence of two witnesses. THOMAS F. PAYNE. Witnesses:
