SUPPLY-VALVE FOR WATER CLOSE'T'S, 84C.

SPECIFICATION forming part of Letters Patent No. 300,540, dated June 17, 1884.

Application filed November 22,1883. (No model.)

To all whom it may concern:

Be it known that I, HENRY O. Wnnmm, of Boston, in the county of Suffolk and State of of Massachusetts, a citizen of the United States, have invented certain new and useful Improvements in Supply-Valves for ater- Glosets and Kindred Structures, of which the following is a specification.

My present invention is an improvement upon that patented to me by United States Letters Patent No. 274,156, dated March 20, 1883, that improvement consisting in certain means, hereinafter set forth, whereby I am enabled to obtain a preliminary flush of the closet or urinal prior to its use by the occupant, as well as the gradual after-flush de scribed in that patent.

The drawings represent a flushing apparatus arranged to accomplish both of these objects, Figures 1, 3, and?! being sectional views of one form of my improved apparatus, Figs. 5 and 6 being sectional views, and Fig. 7 an end view, of another form of the same, and Fig. 2 being a top view of my improved flushinglever.

In the drawings, A represents a flushingtanl: provided with a supply-pipe, (not shown, opened and'closed by a ball cock and float, in the ordinary manner.

13 represents an overflow-pipe, also of ordinary construction, leading from the tank into the flushing-pipe 0. Where this flushing-pipe O connects with the tank A, I provide an enlargement or chamber, D, adapted to contain the amount of water intended to be used in the preliminary flush. A valve, B, when raised or lowered, closes either the passage from the flushingtanl; into the chamber D or from the chamber D into the outlet 0, as the case may be. This outlet 0 connects with the water-closet or urinal to be flushed. A cup or bowl, F, is employed as in the Letters Fatent referred to. An extension from the bot-- tom of the cup or bowl may carry the valve E, already referred to, or this valve E may be worked independently of the cup F, as shown in Figs. 1, f3, and 4:. The lever G in Figs. 5, 6, and 7 is the same as that shown in the granted Letters Patent before referred to.

In Figs. 1, 3, and 4 a lateral extension, 1, of the.inncr lever, which carries the Weight, is made to project beyond and under the outer lever, (see Fig. 2,) for a purpose hereinafter explained. The position of these various parts when the closet is not in use is as shown in Fig. l, the outlet from the chamber D into the outlettube 0 being closed by the valve E, and the cup F being at its lowest point in the tank. The cord'll, attached to the outer arm of the lever, I prefer to fasten atits lower end to the seat of the water-closet or the stand of the urinal, such seat or stand being constructed in the well-known manner, so that it will be forced down by the weight of a person using the closet or urinal. When such weight is applied, the lever G is moved to the positionshown in Figs. 3 and 5, and the valve E, which is connected with the outside lever, is raised until it closes the upper orifice of the chamber D, or that one which connects it with the tank. The lower orifice of the chamber I) being thus opened, the volume of water contained in it passes down through the educt G and gives a preliminary flush. hen the use of the closet or urinal has ceased, and its occupant has left its seat or standard, the cord H being no longer held down, the outer part of the lever G falls by reason of its weighted overbalance. inner part, however, being still held up bythe movable counter-balance I, the apparatus remains in the position shown at Figs. 4 and 6, in which the valve B, being away from either orifice of the chamber D, and the passage from the tank A through the chamber D to the educttube being open, the water in the supply-tank passes down through the educt-tube G, and flushes the closet or urinal until its level has fallen suiiiciently below the level of the top of the cup F to make the weight of water retained in the latter sufficient to overbalance the moving weight 1'. hen this takes place both parts of the lever G fall with the cup F until the valve E is carried down to and closes the passage from the chamber D to the eductpipe 0. The escape of water from the tank then ceases, the apparatus being brought back to its original position, as shown in Fig. 1, and the floatiu g ball-cocl-t allows the tank to re The Y fill till the water regains its normal highest level.

It is desirable to insure the opening of the passagefrom the tank through the chamber D to the outlet 0 from the time that the weight is removed from the seat or standard of the water-closet or urinal until enough water has escaped from the tank and passed through the outlet 0 to accomplish the second or after flushing. To do this the valve E must be held for such length of time away from either opening. One method of so operating the valve E is shown in Figs. 5, 6, and 7, where the stem of that valve is attached to and moves with the cup F, and where the compound lever shown in the granted patent is used. In this construction the cup F is attached, preferably by means of a cross-bar, f, to the two parts of the lever G by means of connections of variable lengths.

The result of making the connections of variable lengths is as follows: When the closet or urinal is occupied, and the flushing apparatus is in the position shown at Fig. 5, the tension upon the shorter flexible supports attached to the outer part of the lever G holds the valve E up against and closes the passage from the flushing-tank. When the weight of the occupant of the closet or urinal is removed-that is to say, when the apparatus has assumed the position shown in Fig. 6the falling of the outer part of the lever G allows the cup to drop part way, and the passage from the flushing-tank through the educt-pipe O to be open, the valve and cup being arrested at this intermediate position by the tautening of the connection attached to the inner part of the lever G, which has not yet fallen. Finally, when the fall of water in the flushingtank has caused this inner part to overbalance, the cup and valve descend until the latter closes the entrance into the pipe 0 and cuts off the further flow of water through it, and this state of things continues until the closet or urinal is again. made use of. The second method of so operating the valve E is shown in-Figs. 1, 3, and 4., where the lever G is provided with a lateral projection for arresting the fall of the outer part by the inner. The valve E is connected with the outer part of such a lever, G, bymeans of a cord or wire passing through a tube extending through the cup F to a point higher than the top of its sides. The condition of the apparatus before the closet or urinal is used is as represented in Fig. 1. The weight of the occupant causes the apparatus to assume the position shown in Fig. 3. The accurate seating of the valve E against the upper orifice of the chamber D may be insured by the insertion of a spring either in the connection which lifts the valve or in the cord H, as shown in Fig. 3. When the weight of the occupant is removed from the water-closet or urinal, the flushing apparatus assumes the position shown in Fig. 4, where, by the fall of the outer part of the lever G, the valve E. has descended until the outer lever is arrested at such a point that the valve stands substantially midway of the two orifices of the chamber D and allows the free passage of water through that chamber and the flushing-pipe 0.. Finally, when the after flush has ceased and both parts of the lever G have tipped inward, the outflow of water from the tank is stopped and the water therein returns to its normal level, as shown in Fig. 1.

As will be seen, the detention of the valve E until the cup has descended may be accomplished at the lever or by making the connections of variable lengths. I regard these asequivalent means of carrying out the same idea, which is to so regulate the position of the valve E with reference to the passage from the tank through the chamber D to the flush- I ing-pipe that that passage will remain open from the time the closet or urinal is quitted till a definite and predetermined amount of water has passed down for flushing purposes.

It is obvious from the above that the stop on the compound lever or the connections of variable lengths may be used, whether the pan F and valve are arranged to move together or separately, and that the size, depth, and relative position of the pan F may be altered to obtain the precise length of flush desired.

I claim-- 1. In a flushing apparatus for water-closets and kindred structures, the improved compound or double lever herein described, consistin g of two counterbalanced-lever parts, one of said parts being provided with a suitable stop .adapted to check the fall of the other at a given point, substantially as and for the purposes herein described.

2. In a flushing apparatus for water-tanks, the combination of a two-part or double lever with a water-detaining pan, an independentlymovable valve for regulating the outflow of water from the tank and chamber D, and means, substantially as described, for holding said valve away from its seats during a predetermined flushing period, all substantially as herein described and shown.

3. The combination, with a double or compound flushing-lever, of a water-detaining cup carrying a valve for-opening and closing the flow of water from a chamber, D, the said cup being connected to both parts of the compound lever with connections of variable lengths, all substantially as herein described and shown.

4. The combination, with the main flushingtank, of a chamber, D, a valve for opening and closing the inlet to and exit from said chamber, a water-retaining pan or cup, and means, substantially as described, whereby the said valve is automatically held, so as to keep open both the entrance to and exit from the chamber during the ,flowing out of a predetermined quantity of water from the main tank, and no longer.

5. The combination, with a valve for open.
