WATER-FAUCET.

I SPECIFICATION forming part of Letters Patent No. 227,598, dated May 11, 1880.

Application filed January 10, 1880. Q I

To all whom it may concern Be it known that 1, JOHN TUCKER, of the city, county, and State of New York, have invented certain new and useful Improvements in Water-Faucets, of which the following is a specification.

In the accompanying drawings, Figure 1 represents a vertical central section of my improved water-faucet, and Fig. 2 1s a bottom view of the cap-piece and actuating thumblever of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to an improved faucet for wash-basins, &c., in which the pressure of the water closes the faucet in an automatic and perfectly-noiseless manner, and in which the annoying leaking is fully obviated.

The invention consists of a barrel having a seat below its disehargespout, against which a hollow piston having an upper solid stem or spindle is forced by the pressure of the water. The faucet is opened by a lever pressing down on the extended stem or spindle of the piston, the stem being tightly connected to the barrel by an elastic diaphragm, and an upper valve closed when the lower piston-valve is opened to prevent leaking at the upper part of the faucet. The depressing-lever is connected by a screw-button at the rear end to the closing top cap of the faucet and guided in slots of the same.

. Referring to the drawings, Arepresents the barrel of my improved faucet for water-basins, 850., which is cast in the usual shape and size, and provided at the lower part with a strainer, B, for retaining any coarse impurities. Within the barrel A is guided a hollow piston, O, which is open at the bottom and closed at the top, so that the air at the interior of the same acts as a cushion for the water and prevents the shocks which generally take place when closing the faucets. The lower part of the hollow piston has exterior projecting guidestuds a, by which it is held in proper position within the barrel. At the upper end of the hollow piston O is arranged an elastic collar, b, which is screwed on the threaded shank O of the piston, said collar being pressed by the water tightly against a seat, I), of the barrel, so as topreliably shut off the water, the piston moving with the water in closing.

The upper part, (I. of the shank G is made square and guided in a corresponding hole of the upper part of the faucet-barrel above the discharge-spout, the square portion steadying' cured tightly to the piston-shank O by a collar and nut, 9, above the valve 0, and into a recess of the upper part of the barrel A by a washer, flanged cap A, and flanged connecting screw-nut A as shown in Fig. 1. The

rounded-off upper end of the shank G is acted upon by a thumb-lever, D, which passes diaf metrically through the cap, and is connected thereto at one side by a sinall knob or button, h, screwed onto the projecting rear end of the lever, said rear end passing through a perforation of the cap, while the front part of the lever is guided at the opposite side of the cap in a slot. h, of the same.

By pressing on the front end of the thumb-lever D the piston is lowered and the lower valve, 1) I), opened, so as to admit the discharge of the water. The upper valve is at the same time pressed down on its seat, so as to prevent any escape of water and leakage at the upper part. This is furthermore prevented by the rubber diaphragm, which not only serves as a packing against the escape of water, but also as a spring for returningthe piston into closed position as soon as the pressure on the lever is released.

The air-cushion in the hollow piston, the rubber valve on the head of the same, and the rubber diaphragm produce the perfectly-noiseless shocks incident to almost all automatic faucets of this class. 1

Havingthus described my invention, I claim as new and desire to secure by Letters Patent- 1. As an improvement in water-faucets, the combination of the barrel A, having a seat, I),

working of the piston and do awaywith the IOO below the discharge-spout, with a vertically-- guided piston, .0, having a lower hollow part with an elastic valve-head, b, and a solid stem or spindle, O, at the upper part, substantially as set forth,

2. In a water-faucet, a vertically-guided piston, 0, having a hollow lower part, which forms at its interior an air-cushion for the water, and a solid upper stem or spindle, 0, substantially as-described.

3. In a water-faucet, the combination of the faucet-barrel A, having an upper valve-seat, 6, with a; "erticallyguided piston, 0, having an upwardly-extended and threaded shank, O, with a fixed cup-valve, e, and with an elastic diaphragm, f, secured to the upper part of the shank-and faucet'barrel, to prevent leakage, substantially as described.

4; -In a water-faucet, the combination of the faucet-barrel A and of a vertically-guided hollow piston, (3, having a lower valve, 0 b. an upper valve, 6 e, and an elastic diaphragm, f,

with an actuating-lever, D, substantially as specified.

5. In a water-faucet having an upper and lower valve, an elastic diaphragm, f, secured above the upper valve of the faucet, to prevent leakage and assist the closing of the lower valve, substantially as set forth.

6. In a water-faueet, the combination, with the cap-piece A, having a rear perforation and front guide-slot, of a thumb-lever, D, secured to the cap by a button or knob, h, screwed to the projecting rear end of the lever, as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 8th day of January, 1880.
