VALVE FOR WATER-CLOSET RESERVOIRS.

SPECIFICATION forming part of Letters Patent No. 341,372, dated May 4, 1886.

Serial No. 195,200. (No model.)

To all whom it may concern:

Be it known that I, JAMES G. BRYAN, a citizen of the United States,residing in Lavallette, Ocean county, New Jersey, have invented certain Improvements in Valves for Water-Closet Reservoirs, of which the following is a specification.

One object of my invention is to so construct a valve for water-closet reservoirs that the proper operation of the valve will be insured when the level of water in the reservoir is low, and a further object is to prevent the roaring noise due to the rush of air into the overfiowtube of the valve.

In the accompanying drawings, Figure 1 is a sectional view of the valve and sufficient of the reservoir to illustrate my inventign, the valve being closed; Fig. 2, a similar view showing the valve open; Fig. 3, a sectional plan on the line l 2, Fig. 2; Fig. 4, a sectional plan on the line 3 4, Fig. 2; and Fig. 5,3. view showing the air-cut-ot' valve in a different position from that shown in Figs. l and 2.

A represents part of the casi ng of the waterreservoir, to which is secured the'dischargetube B, a flange, a, on which bears upon the lead lining of the reservoir,while a retainingnut, c', bears upon the under side of the shell or casing of the reservoir. To the flange a is screwed the lower section, I), of the valve-casing D, the upper end of said section b being screwed into a ring, cl,which also receives the lower end of the upper section, b, of the casing, a partition, e, being conned between the two sections, as shown in Figs. 1 and 2.

Fis a valve, which is adapted to a raised annular seat formed on the upper end of the dischargetube B, this valve having a tubular stem ,G, which passes through a stuffing-box, g, on the partition c, and has a piston, la, fitting snugly to the upper portion, b', of the valvecasing, and provided with a suitable packing, so as to prevent leakage. In this piston is an openinga', to which is adapted apivoted valve, k, by the adjustment of which the area afforded by the opening t for the exit`of water may be increased or diminished, and in the partition c is an opening, m, to which is adapted a iapvalve, n, opening upward.

XVhen the valve-stem G is lifted so as to raise the valve F from its seat, as shown in Fig. 2,

water can flow freely from thereservoir through ports p in the lower portion of the valve-casing D, and can pass from the reservoir through the discharge-tube B. As the valve is lifted, water is drawn through the opening m in the partition e into the chamber of the valve-cas ing above said partition, and when the valvestem is released and said valve-stem is depressed, owing to the action of a weight, s, supported thereon, the descent of the valve is retarded to an extent dependent upon the adjustment of the valve 7s on the piston 7L, for as the valve n prevents any escape of water downward through the opening n in the partition e all of the water trapped between said partition and the piston h of the valve-sten1 must escape through the contracted passage afforded by the partially-obstructed opening i, so that the time occupied by the valve in its descent, and the extent of flushing of the water-closet can be regulated to a nicety by the adjustment of the valve 7c.

As the supply of water for regulating the descent of the valve is drawn from the lower portion of the valvecasing, the apparatus will work properly, even when the level of water in the reservoir is low, thus overcoming an objection to that class of valves in which the supply of water for regulating the descent of the valve is received from the top of the valvecasing as the valve is lifted.

To the upper end of the tubular stem G of the valve is secured a cap, J, in which are a series of ports, w, closed, under ordinary circumstances, by a ring, fr, carried by an annular fioat, y. Access of air to the tubular stem G of the valve is thereby cut off,and the roaring noise due to such inlet of airis effectually prevented. As the water rises in the reservoir, however, to the, overtlow-point,the valve rv is lifted by the fioat y, so as to open the ports w and permit the surplus water to escape through the hollow stem of the valve, as usual.
