.To @ZZ whom may concern:

Be it known that l, JEROME F. BRYANT, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented certain new and useful Improvements in Water-Closet Valves, of which the following is a full description. reference being had to the accompanying drawings, in which- Figure l is a vertical section showing the cut-off valve in its lowest position; Fig. 2, a similar section showing the valve in its highest position. 4

The object of this invention is to provide a self-acting valve for water-closets which can be operated from the ordinary watersupply without a separate water-reservoir, and which will give the basin a fore and after wash; and its nature consists in the several improvements hereinafter' described and claimed.

In the drawings, A indicates the casing or shell; B B, the cylinder or tube in which the supply-valves operate; C C', the cylinder or tube in which the cutoff valve operates; D, a separate cylinder or tube located in the part or section Bof the supply-cylinder; E, upper supply-valve; F, lower supply-valve; G, spider or bridge; H, water-supply pipe; I, dischargepipe; J, valve-rod; K, valve-tube; c b, valves; c d, valve-seats; c, packings; j', Valvenuts; g, valve or stop for pipe K; h, arms connecting the valve Fwith the tube K; ij k lm n o, ports or openings.

The shell or casing A is usually made of a single casting, of brass or other suitable mater-iai; but, it' desired, the cylinders may be separately made and afterward attached together. The supplycylinder is provided with a chamber or section, B, at its upper' end, which chamber is provided with a valve-seat at its lower end, as shown. Its lower end is provided with a chamber, B', which chamber is provided with a fixed tube, l), screwed into the middle portion, as shown. Its lower end is provided with abridge or spider,which supports the stop g. The. tube D is sufficiently smaller than the chamber B', to afford the water space or passage between the two. In the upper chamber the cylinder E is located, which cylinder is most easily made hollow, and it is provided with the three openings or (No model.)

ports 7c Z m, and its lower end is provided with a valve, through which passes a small tube, K. This tube has attached to its lower end, by means of the rods or bars h, a cylinder, F, which in its upward position is arranged to close the passage around or at the side of the cylinder D. The cylinder F is provided with rings, upon which the packing e is located, and the lower ring is attached to a screwthread, so that the packing can be compressed or adjusted io make it tit against the walls of the chamber B. The upper end of this supply-cylinder is covered with a screw-cap, through which the valve'stem J projects, and C its lower end is arranged to be coupled with the watersupply pipe by an ordinary coupling or union.` This cylinder is provided with the ports or water-passages ,j. mand o, through which water passes to the cut olic cylinder.

The cut-off cylinder is provided with two chambers, C C', which are covered at their outer ends with caps, and neartheir meeting are provided with valve-seats,and at this point the escape or discharge pipe I is located, as shown. Within these chambers ai e located the valves ay b, which are connected together by a stem or bar. These valves are provided with packings e and packingnuts j'. These valves are not quite close fitting except when on their seats c d.

The pipe H in cities ortowns which are provided with water-works is directly connected with such water-supply, and in places where there is no suoli supply, then it may be connected with an elevated reservoir or other supply, and in cases where the pressure or head is not sufiicient to throw the supply-valves up into the position shown in Fig. l a spring may be placed between the valve or cylinder F and the bridge G to aid in throwing the valve up when the seat -pressure is removed from the rod J. There the water-supply has any considerable head or force, such spring will not be required, as the pressure of the water will be sufficient to close it. I have described the valve as in a vertical position, and it will ordinarily be in such position; but it will be understood that it maybe placed horizontally, or at any angle, as maybe most convenient, and it will also be understood that the pipe I leads to the basin or bowl of the IOO ` is called the ,fore wash.

water-closet, and that it is to be attached to such basin in the ordinary manner, and also that the pressure upon the Valve-rod J is the pressure of the person occupying the seat, the seat being hinged for such purpose.

In operation, when the device is at rest, the parts will be in the position shown in Fig. 1. When the rod J is depressed, the valve-cylinder E is, depressed to the position shown in Fig. 2, when the water inthe cylinder C passes through the openingsj 7c into the hollow valvecylinder and out through the openings or passages m i, into the cylinder beneath the upper valve, so that there will be no vacuum, and as the valves a b are not close tting when the valveis oft' its seat a portion of the water may pass around such valve, and any excess will pass out at the pipe I. The valves a b are forced into this upper position by the water passing in at the passages n o, and while the valves are ascending the water from the passage o iows through the pipe I, and being thus free to escape the pressure from the water passing through the opening or port n causes the valve b to slowly ascend until it reaches the seat d and stops the ilow. This gives the basin what The descending movement of the valve-cylinder E causes the open end of the tube K to press against the stop g, thus closing the lower end of said tube. When the pressure is removed from the seat, the valve b being closed, the water-pressure causes the valve cylinder E to commence ascending, and as it starts the end ofthe tube K is opened, so that water is free to ow through that and through the opening kj between the cap and valve a, which causes the valve a to commence descending, and the water also flows in through the openingt'and passes out through the tube I while the valve a is descending, and it passes through both openingsi and o until the valve a reaches its seat c, when the flow again ceases, and this movement has given the after wash. When the valve-cylinder E has reached its upward limit, which is determined by the cylinder-valve F, the space between the chamber B and the tube or cylinder D is closed, and this movement closes the ports or openings o n, so that the water which passes through the pipe K and through the openings Z'j and through the opening i holds the valve a to its seat until the rod J is again moved down.

By this construction and arrangement of the parts I aml enabled to connect a watercloset with the ordinary supply-service of a city and give the basin a fore and after Wash and dispense with reservoirs and other devices which have heretofore been used for this purpose, and I produce a device which will automatically close while the weight is upon the rod J, and automatically close after the weight is removed.

4What I claim as new, and desire to secure by Letters Patent, is- Y l. In a water-closet valve, the combination of a cylinder having chambers B B, valves E l F, and rod J, a cylinder having chambers C C', valves a b, and valve-seats c d, and the discharge-pipe I, said cylinders being provided with communicating passages, substantially as specified.

2. In a water-closet valve, the cylinder having the chambers or sections B B and tubes D and K, in combination with the valve-cylinders E F and rod J, substantially as specitied.

3. In a Watercloset valve, the combination of a cylinder having chambers B B', the rod J, the cylindrical valve E, the tube K, and the stop g, substantially as described.

4. In a water-closet valve, the combination, with the cylindrical chambers B C, having passages ij, of the valve a, the cylindrical valve E, having passages 7c lm, and the rod J, substantially as set forth.

5. In a water closet valve, the combination, with the cylindrical chambers B C', having passages o n, of the tube D and the cylindrical Valve F, substantially as specified.

6. The combination and arrangement of a cylinder having the chambers B B', with a cyl-v inder having the chambers C C', valves E F a b, and openings j n o and k lm, the pipes H I, tubes D and K, and stop g, substantially as and for the purpose specified.
