IMPROV EMENT IN VALVES -FOR WATER-CLOSETS.

Specification forming part of Letters Patent No. 148,098, dated March 3, 1874; application filed January 28, 1874.

To all whom it may concern:

Be it known that I, ALFRED TYLOR, of the city of London, in the Kingdom of England, have invented certain Improvements in Valves for Water-Closets, and analogous purposes, of which the following is a specification:

This invention relates to means for regulating and arresting the flow, and preventing the waste, of water, and to prevent shock in closing the valve; also, to prevent retaining water below the valve.

I provide an air-pipe, connected to the case below the valve, to admit air, and allow any water that may be contained under it to pass out. The upper open end of this air-pipe is higher than the reservoir from which the water is received. I employ an adjustable ring, screwed on the outside of a movable actuatin gpiece, for regulating the gradual seating of the valve. I provide a screw, arranged in the back of a plunger or plug, which forms the valveface for regulating the height of the drop.

In the accompanying drawings, Figure 1 is a side. elevation. Fig. 2 is a vertical section. Fig. 3 is a vertical transverse section at right angles to Fig. 2. Fig. 4 is a horizontal section on line 00 at.

In the drawing, A represents the shell or case, with the usual inlet and outlet openings, in which is arranged the movable cylinder or socket B, provided, at its upper end, with a stem passing through a suitable stuffing-box,

a, and connected to lever b, which may be' weighted or connected to a handle for operating the valve. In the movable cylinder is arranged the movable plug or piston-plunger O, fitting loosely therein, and having in its face any suitable packing. In the back of this piston-plunger O is inserted a small screw, 0, (see Fig. 3,) which regulates the lift of the said plunger by its contact with the inside face of the movable cylinder B. On the side of the ease or shell A is arranged a small passage, d, communicating with the space above the movable cylinder B, and the flow of water to which is regulated by a small screw-valve, or its equivalent, D, passing through a suitable stuffing-box. Below the seat of the valve a small airpipe, G, is connected, by which air is let into the case, thus allowing any water contained therein to descend after the valve is water to the stufling-box a. F is a ring-valve,

fitting tight and easy in the caseA, and adapted to form a nearly or quite tight joint, with the 'fiange B projecting out from the top of the socket-piece or cylinder. On its interior are projections f, reaching nearly to the body of the cylinder B, and adapted to be struck and lifted by the adjustable ring B which is screwed upon the cylinder B, and, by being turned more or less in one direction or the other, will stand higher or lower.

The action of this arrangement is as follows: On raising up the actuating-cylinder B, contained in the case A, it takes up the plunger or plug 0 from off the raised seat A and opens the outlet-orifice A raising, also, at the same time, the ring-valve F by means of its projeo tions f f, which come in contact with the ad justable ring B on the circumference of B, this ring being made adjustable to regulate the lift of F. On the upward movement of B ceasing, the movable regulatingvalve 0 falls gradually to its seat, and the ring valve F takes the po* sition shown in Figs. 3 and 4., and both it and B gradually descend.

By this arrangement the quantity of water for which the apparatus is adjusted flows with certainty; and a slower or earlier release of the actuating arrangement will not vary the quantity, and the valve cannot be left or kept open, or partially open.

The loose piece or drop 0 will, when the valve is closed, be embraced within the socketpiece of cylinder B, with the screw 0 touching the interior at the top. When the lever b, and,

consequently, the socket or cylinder B, is suddenly lifted, it draws up with it the drop 0, and thus the valve is opened. It immediately commences to close, the drop sinking out of the socket-piece B as fast as the slight leakage of the water up its sides will allow. It sinks faster than the socket piece B, but the latter. also commences, at the same time, to sink slowly. The flange B rests tightly on the ring F after it has descended a little, and thenceforward its sinking is very slow, because, by the aid of the ring F, it makes a tight-fitting piston. It can only descend so fast as the water can leak upward past it, except when, by opening the valve D, the water is allowed to also flow up through the passage d. In practice, the valve D will usually stand a little open.

less high, the screw 0 is set higher. If it is desired that the ring F shall be lifted less high, the adjustable ring B is set lower. If it is desired that the cylinder B shall descend more rapidly after it comes in contact with the ring F, the Valve Dis opened farther. If, from any cause, the piece 0 sticks fast in the cylinder B, the only evil will be that the valve will remain open a little longer. It will certainly close when the cylinder B finally descends.

I claim, in valves for water-closets and analogous uses--- 1. The adjustable ring B on the piece B, in combination with the ring-valve F and flange If it is desired that the piece O shall be lifted.

B, and adapted to operate with the casin g A and the water-connections, as herein specified.

2. The combination of the movable face-piece G and carrying-cylinder B, both slowly sinking, as shown, and adapted to serve, by the sinking of both together, or of the face-piece alone, as herein specified.

3. The adjustable screw 0 in the movable face 0, in combination with the carrying socket or cylinder B, as specified.

4.. The air-pipe G, leading from the passage below the valve to a level higher than the water-supply, as and for the purposes described.

In testimony whereof I have hereunto set my hand this 9th day of July, 1873, in the presence of two subscribing witnesses.
