JOHN C. G. HUPFEL, OF NEW YORK, N. Y.

SELF-CLOSING FAUCET.

SPECIFICATION forming part of Letters Patent No. 241,018, dated May 3, 1881.

Application filed February 26, 1881.

T 0 all whom it may concern:

Be it known that I, JOHN C. G. HiiPFEL, of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Faucets, of which the following is a specification.

My invention has for its object to provide a faucet in which the valve is automatically closed against its seat by the pressure of water, and which valve can be conveniently removed from its seat to permit the passage of water by the simple pressure of the thumb or finger. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a vertical sectional view of the faucet; Fig. 2, a side View of the same; and Fig. 3 is a front elevation showing the protectin g arms.

Similar letters refer to similar parts.

Referring to the drawings, the letter A indicates the body or casing of the faucet, provided with the usual inlet and outlet chambers c and b, the dividing-partition of which chambers is provided with the passage 61, constituting a valve-seat. The top wall of the casing A is provided with a concaved or cup-shaped recess on its exterior, surrounded by the shoulder f, which is externally screw-threaded. Upon the upper edge of the shoulder f is supported a horizontal imperforate flexible diaphragm, J, which is securely fastened in position by the screw-threaded retaining-ring I, adapted to the threads on the shoulder f.

The letter B indicates the valve-rod, having at or near the center of its length the valve 0, which is adapted to set into the passage-way d. The lower end of the valve-rod rests loosely in the plug H, and its upper end extends through an opening, 0, in the concaved top wall of the casing, but terminates below the diaphragm J in a button or rounded head, (1, thus permitting free vertical play of the valve-rod independent of the diaphragm.

It should be observed that the diaphragm is upon the exterior of the faucet, and owing to the concave recess in the top wall of the casing said diaphragm can be depressed by the simple pressure of the thumb or finger for the purpose of opening the valve, as hereinafter explained.

The casing or body A is provided with the (Model.)

screw-th readed in lets F and the screw-threaded outlet F.

Gindicates an ordinary hose-coupling or nozzle, and F indicates a screw-threaded neck, into which the screw-threaded plug H is fitted. The screw-threaded plug H is provided with a central guideway, into which the lower end of the valve-rod B is arranged and adapted to play vertically.

In Fig. 3 the letters K indicate the projecting arms, arranged at the sides of the bodyA and extending to or above the plane of the ring I, which arms are designed to protect the diaphragm when the hose to which the faucet may be attached is thrown or dropped upon the ground. It is, of course, obvious that these arms may be dispensed with when the faucet is used for basin purposes. It is also obvious that, when desired, I can place a small metallic or other spring under the end of the valverod B to facilitate the closing of the valve, although the same is not shown in the drawings.

In operation the hose is coupled at the end X and the nozzle at the end X, and the faucet is then ready for use. The water being turned on enters the chamber 0, and pressing against the lower side of the valve 0 forces it upward into the passage-way d and cuts 0d the egress of the water. When the valve is raised the button or head (1 of the valve-rod is raised and touches lightly against the inner face of the yielding diaphragm J. When it is desirous to permit the escape of the water through the faucet it is only necessary to press down on the diaphragm with the thumb or finger, and the valve is depressed away from the passageway (I. the water to escape, and the simplicity of the arrangement prevents the faucet from easily becoming inoperative.

It is obvious that when I desire to use the faucet for basin purposes I suitably extend the outlet and inlet branches.

By the use of this faucet all overflows are prevented and avoided, because the faucet will not permit the passage of water unless the diaphragm is depressed, and immediately on releasing the same the pressure of the water automatically closes the valve.

hat I claim is 1. The casing or body of a faucet provided with the recessed top wall, and the flexible When not in use it is impossible for imperforate diaphragm arranged over the same and adapted to be depressed by the thumb or finger, in combination with the loose-sliding valve-rod extending through the top wall of 3. In a faucet such as described, the body A, having the chambers band 0, perforated concaved top Wall, the threaded shoulder f, the threaded coupling-extensions F, F, and F and the exterior laterall y-projectin g armsK K, 20 all substantially as shown and described.

In Witness whereof I have hereunto set my hand and affixed my seal this 24th day of February, 1881.

JOHN G. G. HUPFEL. [L. 8.]
