VALVE AND RESERVOIR FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 373,015, dated November 8, 1887.

Application filed March 31, 1884. Serial No. 126,132. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM S. COOPER, a citizen of the United States, and a resident of Philadelphia,Pennsylvania,haveinvented certain Improvements in Reservoirs and Valves for Water-Closets, of which the following is a specification.

The object of my invention is to overcome the objectionable gurgling or roaring noise usually caused by the escape of water or air through the overflow-pipe of a water-closet reservoir; and this object I attain by the use of a float-valve adapted to close the entrance to said overflow-pipe when the level of water in said reservoir is low, but free to rise as the level of water rises, so as to permit the escape of the surplus water through the overflowtube.

In theaccompanying drawings, Figure 1, Sheet 1, is a longitudinal section of my improved water-closet reservoir, the valve being closedthat is to say, in the position which it occupies when the valve of the closet has been closed and the flow of Water has ceased. Fig. 2, Sheet 2, is a section of the reservoir with the valve in the position which it as sumes when the valve of the water-closet has been opened; Fig. 3, a section of part of the reservoir, showing the valve as it appears after the valve of the water-closet has been closed, but before the flow of water has been cut off; Fig. 4:, a transverse section of part of the reservoir on the line 1 2, Fig. 2; Fig. 5, Sheet 1, a section of part of the valve in adifferent position from that shown in Fig. l, 2, or 3; and Fig. 6, a sectional plan on the line 3 4, Fig. 1.

A is the reservoir, in the bottom of which is a depression, a, separated from the main reservoir by a partition, I), resting upon a shoulder, c, and confined by a stud-bolt and nut, said partition forming beneath the reservoir A a chamber, B, which can communicate with the reservoir through an opening, I), in the partition, this opening being surrounded by a projecting ring, cl, which forms a seat for a valve, D, the stem D of the latter being connected by any suitable means to the valve-operating lever of the water-closet.

In the bottom of the casing a of the chamber B is an opening, 6, and to said casing is secured a chest, F, the packing-ring f, which intervenes between the casing a and the upper end of the chest F, surrounding the openinge and forming another seat for the valve D.

Forming part of the valve is a tubular projection or plunger, D provided with slots the lower end of this tubular plungerbeing furnished with a packing-ring, h, which fits snugly in a cup, G, suspended within the valve-chest F, the cup being of less diameper than the chest and supported therein by a notched ring, so that w'ater can flow freely between the two.

To the lower end of the tubular plunger D of the valve D is adapted a valve, H, consisting of a disk, 2', with a projecting flexible ring, 1', this valve having a stem, m, and being sup ported by a spring, m, interposed between a spider, m", in the cup G and adjustable nuts m at the upper end of the stem. The disk i has an opening, 12, formed in it, and on the bottom of the valve is a strainer, 19, of perforated plate or wiregauze.

Secured to and projecting upward from the valve D is a tube, J, which communicates through the valve with the tubular plunger D" of the same, and on the upper end of this tube rests a float, K, consisting in the present instance of a sheet-metal cup with a central tube, K, surrounding but somewhat larger in diameter than the valve-rod D.

A weight, M, surrounds the tube J and rests upon a ring, 8, on said tube, and a screen or cage, W, ofperforated plate or wire-gauze, is secured to the partition a, and has an opening in the top for the passage of the weight, this screen serving to prevent the access to the opening b of sticks or other foreign matter tending to interfere with the operation of the valve D, which is as follows: When the valve of the watercloset is closed, the valve D is in its lowest position and rests on the seat f, as in Fig. 1, the other parts being also in the position there shown, and the chamber B being filled with water. On operating the valve lever of the closet, so as to open the valve of the same, the valve D is raised against the seat 'd, as shown in Fig. 2, thus permitting the water in the chamber B to flow down through the chest F to the closet, the volume and force of the flow being sufficient to effectually fiush and clean said basin, air being slipplied to the chamber B through a pipe, P,

which extends above the level of water in the reservoir A, and is furnished with a hood, 1?. During the upward movement of the valve D the valve H yields downwardly, so as to permit a free flow of water past the sameandinto the bottom of the cup, as shown in Fig. 5. \Vhen the valve of the closet is closed, the valve D is also released and permitted to fall under the influence of the weight M; but this descentis retarded, owing to the fact that the valve H closes against its seat and traps the water in the cup G, the water thus trapped being compelled to escape through the platep and the opening a in the valve, so that the time which elapses before the valve reaches its lowerseat, f, depends upon the area of this opening, and during all this time the water can flow from the reservoir A through the chamber B and chest F to the basin of the closet, thorough washing of which and of the soil-pipe is thereby effected and the filling of the traps insured.

The pipe J is the overflow-pipe, whereby the water in the reservoir A is prevented fromrising above the proper level, and the function of the float K is to prevent the disagreeable noise which results if the water is permitted to flow over the open top of the pipe, as usual, and also to prevent the roaring sound caused by a rush of air into and through the pipe when such action is induced by the flow of water through the chest F. The tube K.

while preventing the admission to the pipe J tube, acts as a cut-off valve to prevent the entrance of air in largevolumes to said tube, the valve being lifted from its seat, however, on an undue rise of the water in the reservoir, so as to permit the surplus to escape through the overflow-tube. This is the novel feature of my invention, the other devices having been shown and described simply to give a proper idea of the working of the reservoir.

I am aware that a water-closet reservoir has been provided with an overflow tube the mouth of which is closed by a valve carried by a pivoted arm the outer end of which is furnished with a float; but in such case the movement of the float -must be much greater than that of the valve on account of the diflerenee in leverage, whereas in my device the valve forms part of the float and its vertical movementis co-extensive with thatof the float.

I therefore claim as my invention 1. The combination of the reservoir, its discharge-valve and discharge pipe, the overflow-pipe, and a float seated upon the upper end of said overflow-pipe and forming a valve to prevent the intlow of air over the upper edge of the pipe, all substantially as specified.

2. The combination of the reservoir, its dis charge pipe, the discharge valve, the overflow-pipe,andafloat-valve closing the entrance to said overflow-pipe, and having a passage of limited area through which air can enter the overflow-pipe, all substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two sub scribing witnesses.

WM. S. COOPER.
