VALVE.

Application filed October 27,1920, Serial 110. 419,922. Renewed Julyv 12, 1924.

To all whom it may concern:

Be it known that I, EARNEST R. W. Lewis, subject of the King of Great Britain, residing at Ponoka, in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Valves, of which the following is a specification.

This invention relates to valves, and the primary object of the invention is to provide an automatically closing valve so constructed that the valve can be held off of its seat to permit the continuous flow of fluid without necessitating the holding thereof by the operator.

Another object of the invention is to pro vide an automatically self closing water faucet that can be moved to such a position I that the same will remain open until the operator desires the same to close, thevalve of which will always sit with the same pressure and in the same position, thereby adding longevity to the same.

Another object of the invention is to provide an improved faucet embodying a valve normally held on its seat by spring pressure, a pin carried'by the valve for engaging in oppositely disposed spiral grooves, the grooves having rest shoulders formed therein for receiving said pin so that the. valve can be held off of its seat as long as the operator thereof may desire v A still further object of the invention is to provide an improved faucet or bib of the above character which is durable and efficient in use, one that is simple and easy to manufacture, and one which can be placed upon th market at a reasonable cost.

l/Vith these and other objects in view, the invention consists: in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part of this specification, in which drawings:

Figure 1 is a vertical longitudinal section through the improved valve.

Figure 2 is a fragmentary vertical section through the valve body showing the formation of the pin receiving grooves therein Figure '3 is a detail horizontal section taken through the improved valve on the line 3-3 of Figure 1.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates the improved valve which. includes the casing or body 5 having the inlet thereof terminating in a nipple6, which can be secured in any preferred mannerto a supply pipe '7. As shown the valve is in the nature of a sinkbib or faucetand is connected to the splash board ,8 of a sink in the ordinary way. The mouth or outlet 9 of the faucet A leads from the chamber 10, which is divided by partition 11 in which is formed the horizontallydisposed valve seat 12.; A. valve 13 ofv theordinary or'any preferred ,constructionis adapted to sit upon the seat 12 and is attached to the lower end of a valve stem 14 in the ordinary manner. The valve stem 14 extends centrally through'the barrel 15 of the "body or casing 5. The upper end of the barrel is closed by, the usual cap16, which also forms a guide for the valve stem. 7 I j The inner surface ofthe barrel "at diametrically opposite points is provided with vertically disposed guide grooves 17 and these grooves have their lower ends terminating in oppositely directed spiral ways 18. ii -rt the point of juncture of the vertically disposed grooves 17 and the spirally disposed grooves or ways 18, horizontally disposed rest shoulders 19 are formed, for a purpose which will be hereinafter .more specifically described.

The valvestem 14 carries in spaced relation to the valve 13a diametrically extending pin 20. The terminals of the pin 20 extend beyond the valve stem 1d and are adapted torest normally within the oppo sitely disposed spiral grooves or ways 18.

In applying and removing the valve and its stem from the valve body 5, the cap 16 is removed from the barrel 15. It thus can be seen'that the pin 20 can be placed in the grooves 17 andslipped downwardly or upwardly as the case may be, into or out of engagement with the ways or grooves 18. The valve 13 isnormally held upon its seat 12 by means of an expansion spring 21 which is coiled around the valve stem 14. As

shown the terminals of this spring 21 bear the valve stem 14: and its cap 16. The extremeupper end of the valve stem 14 has secured thereto in any preferred manner a handle 24, by meansof which the operation of the valve is considerably facilitated. V

In operation of .the improved valve, it is merely necessary to turn the valve stem 14 which through the medium of the pin 20 sliding in the spiral grooves 18 will raise the valve 13 off of its seat 12. The spring 21 engaging the pin normally tends to move the same down the spiral groove 18 and place the valve on its seat 12 for cutting off the flow of the fluid. Thus when the valve stem is released, the valve will immediately ride into correct position on its seat. When it is desired to permit the Water to flow any length of time, the valve stem 14 is turned a sufficient distance as to permit the termina'ls of'the pin 20 to lit upon the rest shoulders 19. This will effectively hold the valve off of its seat against the tension of the spring 21, and when the operator desires the valve to close, it is merely necessary to give the valve stem a very slight turn in the reverse direction, This will move the termi nalsrof the pin 20 ofi of the rest shoulders '19 and the spring will then return the valve to its seat.

IOwing to the exceptionally simple construction of the valve the parts thereof can be readily replaced when desired with a minimum amount of time and labor.

Changes in details may be made without departing from the spirit or scope of this invention; but,

I claim:

l. A valve comprising a body having a discharge outlet and an inlet way, a chamber'interfposed between said inlet and said outlet, a valve seat formed in said chamber, a valve for said seat having a stem, a vertically disposed barrel formed in said body, a

cap carried by said barrel and arranged to rotatably and slidably receive said stem, the barrel having oppositely disposed spiral ways formed therein and vertically disposed grooves communicating with the upper ends of said spiral ways, apin carried by said stem having its terminals fitted in said ways,

an expansion spring coiled around said stem for normally holding the pin at the lower ends of said spiral ways and the valve on its seat, and stop shoulders formed on said barrel at the point of communication of the vertical grooves and the spiral Ways arranged to receive said pin to hold the valve off of its seat against the tension of said spring.

2. In a faucet, a body having a discharge outlet and an inlet way, a chamber interposed between said inlet and said outlet way, a vertically disposed barrel formed on the body and communicating with the chamber, a valve seat formed in the chamber directly below said barrel, a valve arranged to fit on said seat, a stem carried by the valveand extending through the barrel, a cap carried by said barrel and arranged to rotatably and slidably receive said stem, the 'barrel'having oppositely disposed spiral ways formed therein terminating above said valve seat, and vertically disposed grooves communicating with the upper ends of said spiral ways and opening out through the upper end of said barrel, the'lower end walls of said vertically disposed grooves forming rest shoulders, a pin extending diametrically through said stem having itsterminals fitted in said ways, an expansion spring coiled around said stem engaging the pin and the cap for normally holding the pin at the lower ends of said spiral ways and the valve on its seat, the pin being adapted to rest upon said rest ing shoulders when the valve is entirely'ofi" of said seat.
