T 0 all whom it may concern: Be it known that I, PHILIP Haas, citizen of the United States, residing at Davton, in the county of Montgomery and tate of Ohio, have invented certain new and useful Improvements in Flushing Devices for ater-Closets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to the class of water closets and consists in an improved valve construction for use in connection with a flushing tank.

, In the accompanying drawings I have illustrated the best form in which I have contemplated embodying my invention and my invention is set forth in the followingdescription and claims.

In the drawings, F igure 1 is a view of my improved valve construction in elevation.

F ig 2 is an enlarged vertical section of the same when in normal rest position or when discharging water into the bowl. Fig. 3 is a like vertical section showin parts in position when filling the tank. iiig. 4 is a detail showing the construction of the sleeve the interior of which is engaged by the upper valve. Fig. 5 is a sectional view of the admission valve showing the partsv just after the be inning of its upward movement.

In t ese drawings A is the bowl, B the flush tank and C is the water pipe from the A is the seat and a is the seat supand is provided with two arms at extending rearwardly from the point of pivoting, one on each side of theupper valve casing D and bearing against the underside of a ring D surroundin the'valve casing. This ring has an upwar ly extending arm d curving,

inwardly and having its upper end located centrally above the valve casing D. At this point it is connected with valve rod E. This rod extends downwardly through a stufiing box e and through thevalve casingDinto the lower valve casing H. The valve casing D is divided interiorly into two chambers G, G, The horizontally disposed diaphragm separating the two compartments is provided centrally with a threaded aperture and Into this is screwed the lower end of a sleeve e dependin from the stufiing box e. This secures t he stufiing box to the valve casing drawing the same down tightly upon the packing interposed bet ween them. The rod E is provided with a circular valve E" fitted to slide within and.

close-the lower end of the sleeve e.,This valve is of a well known type having flexible material surrounding it formin a packing, and extending below the rigid parts of the valve in the form of a flange. e. A spring e surrounding the rod E is intersed between the valve E and the stuliing x, which tends atalltimes to depress the T body, recessed at the bottom to receive suitable packing to engage the valve seat h and control the admission of water to the interior of the device The valve casing H is provided with a tubular part i to receive and guide the valve H. Below this guide the interior of the casing is expanded at at i. A passage in the nature of a by-pass extends from-the casing abovethe valve H down to the enlargement i, said passage extending slightly-below the said enlargement on one side as shown at 1?. The valve casing H is also provided with an o ening [1. opening into a valve of the hall va ve type A drain ipe J isconnected with this valve and eads to the waste pipe C. This valve acts as a check valve and prevents any influx of liquid from the waste pipe in case of a stoppage-in the same. A pipe K leadin to the bowl is connected with the chamber of the valve casing D while a pipe Z leads from the chamber G to the tank B. The sleeve, e at its lower end is notched or recessed as shown at 6 (see Figs) and at its upper end is provided with openings 6 communicatingwith the chamber G of the valve casing. The lower end of the sleeve 6' being closed, the water as it rises will pass from'chamber G' by pipe Zto the tank B,- until the same has been filled. In this operation the said flange and the interior of the sleeve. The pressure is often so great as to arrest. the movement of the valve. The recesses permit the water to engage the outside of the flange as well as on the inside and the outer pressure relieves this injurious effect, thereby enabling the valve to work easily and increasing the durability of the same.

By referring to Fig. 2 it will be seen that in the normal condition or when the device is at rest, the rod E and valve E are depressed .by the spring 0 and draw down the ring D; The ring 1) depresses the rear end 01' the seat lever, raising the seat from the bowl. The valve H is also depressed and all ingress of water from the pipe I is prevented while the opening into the drain pipe is uncovered and any water in the valve casing D or tank B will flow slowly out into the waste pipe C. On applying pressure to the seat,-the seat lever operates through its connections to lift the rod E thereby raising the valve E within the sleeve and closing the connection with the bowl. The valve H' is also raised and water admitted to the apparatus from pipe I. The valves are mounted on the rod E in such relation to each other that when the-valve E has closed the lower end of the sleeve e, the lower valve H will have been raised only sufliciently to close the drain pipe and to admit water to the lower part. of the bypass at 1? as shown in Fig. 5. The further movement of the seat raises the valve E farthcr within the sleeve and brings the lower end of the valve ll. into the enlargement i of the casing H. The water can then flow around the valve H to the full or approximately the full capacity of the pipe I. On releasing the seat from pressure the spring 0 depresses the valve. rod permitting the water to flow into the sleeve 6 and thence through the o 'ienings c into the chamber G and through pipe K into the bowl, and the movable parts oi the device will be restored to normal position. It will be seen that the openings 6 are considerably above tbclevel of the upper edge of the bowl, and that consetpiently, in case of the stoppage of the waste pipe from any cause, none of the impure contents of the bowl or pipe can flow back into the device. in descending the valve H will first cut oit the influx of Water from the supply pipe I except such as will pass through the downwardly extended portion of the by-pass at i (see Fig. 5) Water will continue to flow through this small aperture for alittle time there .rer and until the valve has completed its downward movement. Just before the valve H reaches its lowermost position the opening into the drain pipe is uncovered. The relation of the parts is such that the valve H will cut off the greater part of the inflow of water before wateris admitted to the interior of the sleeve 6.

The provision for admitting a small initial flow of water to the device, and for continuing a slight flowafter the main current has been in a great degree cut oil, pro. vents hammering in the pipes.

\Vbat I claim and desire to secure by Letters Patent is 1. In a tank flushing device for water closets, the combination with the tank and bowl, of passages for delivering water from the tank to said bowl, a valve for controllin the flow of water to said bowl from the tan the discharge opening from said passages and valve being above the level of the upper edge of the .bowl, an inlet for water and a valve controlling the same, a drain pipe and a check valve forsaid drain pipe, whereby the tank flushing device is secured from all back flow of foul liquid.

2. In a tank flushing device for Water closets, the combination with the bowl, of a,

passage for supplying water to the bowl to flush the same, said passage including an inlet and outlet chamber and a valve casing connecting them, a valve adapted to close the passage by entering and filling a portion of the valve casing extending into the inlet chamber, said valve havin a depending flange of flexible material a apted to be expanded by the water pressure, the'end of the valve casing engaged by said valve being provided with notches or recesses whereby there will be water pressure upon the outside as well as on the inside ofthe said flexible flange.

In testimony whereof I afiix my signature, in the presence of two witnesses. PHILIP HAAS. Witnesses C. .H. W'HITAKE'R, J. K. Moons.
