SELF-CLOSING FAUCET.

SPECIFICATIQN forming part of Letters Patent No. 319,577, dated June 9, 18485. Application filed March 20, 1885. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS HALEY, a citizen of the United States, residing at Gan1- bridge, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Self-0losing Faucets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which-- Figure 1 is a longitudinal vertical section through a self-closing faucet constructed in accordance with my invention. Fig. 2 is an elevation of the valve-stem and its handle. Fig. 3 is a section on the line as a: of Fig. 2. Fig. 4: is a plan of the disk through which the valve-stem passes. Fig. 5 is a vertical section through the center of the disk on the line 3 y of Fig. 4-.

My invention relates to certain improvements in self-closing faucets; and it consists in a novel construction and combination of parts, whereby a smooth and easy action is secured, the friction and wear reduced to a minimum, and the working parts rendered accessible to enable them to be easily taken apart or put together, as hereinafter more particularly set forth.

In the said drawings, A represents the shell of the faucet, which is of the ordinary construction, having the inlet 1), outlet 0, and valveopening (Z.

To a seat on the upper side of the said opening d is fitted the valve B, which is rigidly secured to the lower end of the stem or spindle D, which passes centrally through the top of a cap, G, screwed at e to the upper vertical portion, a, of the shell A, and is provided at its upper end With a cross-bar or handle, H, by which it may be conveniently turned.

At the top of the cap G is a stuffing-box, f, the follower g of which is screwed into the packing-chamber from the inside of the cap, as seen in Fig. 1.

A portion of the length of the stem or spindle D is provided with a series of spiral grooves, t, of semicircular form in cross-see tion, and this grooved portion passes through a central aperture, 70, in a movable disk, I, the said aperture is having a series of spiral ribs or projections, Z, Figs. 4 and 5, which fit into the correspondi ng grooves i of the stem D.

The interior of the upper portion of the shell A is enlarged, forming a shoulder, m, on which rests the disk I, made of such thickness as to project slightly above the upper edge of the shell, whereby, when the cap G is tightly screwed down, the disk I will be confined immovably in place between the shoulder at of the shell and the shoulder a on the inside of the cap, which bears on the disk around its entire edge.

19 is a stiff spiral spring which encircles the stem D between the valve 13 and the disk I, and serves to hold the valve firmly down upon its seat.

When the handle H is turned in the proper direction, the stem D, through the action of its spiral grooves 41 on the spiral ribs or projections Z of the disk I, will be raised, thus lifting the valve B from its seat against the resistance of the spring 2), which will instantly close the valve on the release of the handle,

and by thus securing the disk I between the cap G and the top of the shell A it can be turned on its vertical axis and so adjusted as to cause the cross-bar or handle H to assume any desired position when the valve is closed, this horizontal adjustment of the disk enabling the handle H to be so set that astick or other article could not be placed between it and an adjacent wall or vertical surface to hold the faucet open,as often occurs with self-closing faucets of the ordinary construction where no special regard is had to the position of the handle when the valve is closed.

By providing the stern D with a series of spiral grooves fitting aseries of corresponding ribs in the disk I, as shown, instead of employing a quick screw-thread, as heretofore, a great advantage is gained, as the spiral grooves and projections present smooth rounded surfaces, which will not stick or catch, and will always work freely and smoothly together,

thus reducing the friction and Wear to a minimum, and insuring the faucet always remaining closed when not in use, while the spiral grooves and projections can be produced at much less expense than screw-threads, as the parts to which they are applied can be easily 5 ally therefrom.

What I claim as my invention, and desire to secure by Letters Patent, is

In a selfelosing. faucet, the shell A, provided with screw-threads, to which is secured -10 the cap, the correspondingly screw-threaded cap G, the stationary disk I, rigidly secured between the shell and cap, and provided at its center with an aperture the inner face of which has semicircular projections,which fitbetween corresponding projections on a stem, in comr5 bination with the stem D, which reciprocates vertically as the valve opens and closes, the valve 13, rigidly secured to the stem D, and the spiral spring between the valve B and the disk I, substantially as and for the purposes set 20 forth.

Witness my hand this 17th day of March, A. 1885.

THOMAS HALEY.
