SELF-CLOSING FAUGET.

Specification of Letters Patent. PzttentedFeb.15, 1916. 7

Application fi1ed May 20, 1914. Serial No. 839,916.

My invention relates to a self-closing faucet of the type installed in basins, and one of the main objects of my invention is to provide a faucet which will permit ready access to the valve chamber, and the removal of the valve for examination and repair, without unscrewing the body of the faucet from its seat.

Another object of my invention is to embody my improvement in a type of faucet having a valve which is closed by the pres-v sure of the outflowing water, so as to insure that the valve will properly seat itself without relying on any spring to accomplish this work.

To attain my objects I locate the valvechamber above the spout, extend the valvestem below the chamber, and locate the valve operating means at the inlet end of the spout. I also make the valve stem in two parts readily separated by the lifting of one from the other.

These and other incidental features of my invention, as well as the construction and operation of my device, are hereinafter fully described.

In the accompanying drawings: Figure 1 is a side elevation of my improved basin cock; Fig. 2 is a vertical section of the same; and Fig. 3 is a detail of construction;

The faucet shown comprises a coupling pipe, a, adapted to be connected to the water supply pipe, not shown. Said coupling pipe is made with an enlarged portion, 6, which forms an air chamber. The flat base, 0, of the latter seats on the basin in connection with which my cock is used. Screwed'in the air chamber, 7), is the casing d. Said casing is provided with a valve chamber, 6, the latter being made with a circular valve seat 7. A water duct 9 connects the air chamber, 6, with the valve chamber 6, at a point in the latter above the valve seat f. Directly beneath the valve chamber, e, is a cored-out recess, 1;, in which the valve operating cam finger, m, is adapted to operate. This recess 2' connects directl with the valve chamber, e, by a vertical ore j. Extending transversely from. the casing is the discharge spout The recess, 2', is provided with holes in 1ts sides and bottom which form bearings for the cam finger spindle is and the valve stem portion 0. The valve stem has an enlarged lower section 0, provided with a recess 20, in'which the cam fingerm operates to lift said valve-stem, and guide lugs, 8, made as an integral part of'zsaid stem portion, slide. on the interior of the bore 7' and spacethe valve stem centrally with respect to the valve seat f. The upper section, n, of said stem has as an integral part of. it the flange 1, and a screw member 1 fixed in said upper section, a, isadapted to make a firm but removable connection between the two stem sections. The washer r is held firmly 'down on the seat, f, by the flange 1'. A light compression spring, t, is slipped over the upper end of the valve stem section a. A bearing, to, seats on inner shoulder at the top'of' the valve chamber and forms'a guide for the upper end of the stem section a, and a shoulder for the spring 6, to react against. A cap, 1;, screws on the 'ca'sing'd over the valve chamber, 6, and is adapted, when screwed. down tightly, to clamp the bearing a firmly in place. Furthermore, the upper portion of the valve chamber, e, will act as an auxiliary air chamber. The valveoperating lever, w, is fixed on the spindle, 7a, in the usual manner,

and when operated Will rotate the cam,

finger m so as to lift the valve washer off its" seat. When the lever is released the light spring, t, will insure a positive closure of the valve, but the main closing force will be the water pressure. This construction permits the use of a very light spring, and in many cases the use of a spring may be dispensed with entirely. When the valve washer is to be renewed or examined, the

cap, 0, may be removed and the valve stem section, a, removed by unscrewing it from the section 0.

. I claim: a

1. In a faucet o f-the character described, a valve having a two-piece stem set one on the other, pin-like means detachably connecting these pieces, a valve-head on the lower end of the upper of such stem'pieces, the lower stem-piece being made with a recess, a valve chamber in which the upper stem piece of the valve stem reciprocates, means for guiding the upper end of such upper stem-piece, another chamber below the valve chamber in which the lower piece of the valve-stem reciprocates, the latter chamber having a lateral spout; guiding means for such lower-piece of the stem, a passage connecting said lower chamber with the valve chamber, the valve head on the upper valve stem piece seating on the inlet end of said passage, a spring normally holding the valve-head on it seat, a valve operating handle having a stem traversing said lower chamber, and an arm on said stem bearing in said recess of the lower piece of the valve stem.

2. In a faucet of the character described, a valve having a two-piece stem set one on the other, pin-like means detacha ly connecting these pieces, a valve-head on the lower end of the upper of such stem pieces, the lower stem-piece being made with a recess, a valve chamber inwhich the upper stem piece of the valve stem reciprocates, another chamber below the valve chamber in which the lower piece of the valve-stem reciprocates, the latter chamber having a lateral spout, a passage connecting said lower chamber with the valve chamber, the valve head on the upper valve stem piece seating on the inlet end of said passage, a spring normally holding the valve-head on its seat, avalve operating handle having a stem traversing said lower chamber, an arm on said stem bearing in said recess of the lower piece of the valvestem, a guidepiece removably seated in the upper end of the valve chamber and in which the upper end of the upper piece or". the valve stem reciprocates, and a chambered cap threaded on the upper end of the valve chamber and holding said guide-piece in place.

3. A valve-body comprising an inlet passageway, a valve-chamber parallel and integral with one side of said passageway, and

with which the latter connects, a lateral spout below the valve chamber, said spout having" a chamber provided at its inlet end, and a passage connecting the latter chamber with the valve-chain in combination with a valve consisting of a two-piece stem set one on the other, means connecting said stem pieces so as to permit the upper stempiece to be lifted off the lower stempiece, a valve-head on the lower end or the upper stem-piece, guiding means for the upper end of the upper stem-piece, means for guiding the lower stem-piece in said chamber at the inlet end of the spout, the valve head eating on the inlet end of the passage, a spring normally holding the valve-head on its seat, and a handle cooperating with the lower stem piece, whereby the valv head may be lifted oil its seat.

a. A valve-body comprising an inlet passageway, a valve-chamber parallel and integral with one side of said passageway, and with which the latter connects, a lateral spout below the valve chamber, said spout having a chamber provided at its inlet end, and a passage connecting the latter chamher with the valve-chamber, a removable guide-piece for the upper end of the upper piece of the stem, a chambered cap threaded on the upper end of the valve chamber and holding said guide-piece in place, means for guiding the lower stem piece in said cham her at the inlet end of the spout, the valvehead adapted to seat on the inlet-end ot' the passage, a spring normally holding the valve-head on its seat, and a handle cooperating with the lower stem piece, whereby the valve-head may be lifted off its seat JOHN V.
