SPECIFICATION forming part of Letters Patent. No. 477,717, dated J' une 28, 1892. Application iled November Z5, 1889. Serial No. 331,431. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM A. TURNER, a

citizen of the United States, and a resident of Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Flushing-Valves, of which the following is a specilication,which, taken in connection with the accompanying drawings, contains a full, clear, and exact description of my invention.

Figure l of the drawings represents a por tion of a flushing tank or cistern, shown in sectional view and containing one of my improved iiushing-valves, also partly shown in sectional view and with the separate valves contained therein represented as closed; and Fig. 2 represents the same view, but with the air-inlet valve and the smaller water-valve represented as open.

Similar letters refer to similar parts in the several figures.

The object of my present invention is to provide means fora diminished flow of water after the fiushing-stream has ceased, in order to iill the trap in the closet, and, also, to provide means by which such afterlow may be regulated, and accomplish these results by means of the device represented in the accompanyiug drawings, and hereinafter described. y

In the accompanying drawings, A denotes the tank; B, the water-supply pipe; B', the ball-cock valve operated by the ball or lioat B2 in the usual and well-known manner, by which the water is supplied to the tank and shut oif as the high-water line is reached, (indicated by theline X X, Fig. l.)

C denotes the flushingpipe, through which a stream of water is conducted to the closet, said pipe being screw-threaded to ent-er the tank and being formed integrally with` a shell A', resting on the bottom of the tank and having a stand or overiow pipe C', eX- tending above the high-water line X X.

C2 represents an inverted cylindrical cup, placed over the open end of the overliow-pipe and supported upon the stand C3. The in verted cup C2 extends downward a short distance below the lowwater line, as indicated at YYY, Fig. 2, and is provided with an airiulet C, surrounded by an annular valve-seat a. The inlet C4 is closed by the valve-disk b, carried in the end of the lever c, which is pivoted tothe bracket c. An arm d, adjustably attached by means of a wing-nut d' to the pivoted lever c, carries a hollow ball or iioat e.

The shell A extends laterally upon each side of the stand-pipe C', the extension upon one side having an opening D, provided with a valve-seat f, and closed by a valve g, at tached to the lever h, pivoted to the arm or bracket j, and raised by means of the chain 7c, allowing the waterin the tank to iiow through the opening D to the closet. p

W'lienever the valve-disk g is raised by the chain 7c, the iiow of water through the side opening D and flushing-pipe C will cause a siphonage of the water in the tank through the overliow-pipe, and the flow of water will continue until the water in the tank falls low enough to allow the ball c to fall and open the air-inlet C4.

Upon the upper surface of the lateral eX- tensiou of the shell A', upon the opposite side of the stand-pipe C', is an opening E, similar to the opening D, but smaller in extent, and closed by a valve-disk Z, carried by a lever m, pivoted upon an arm or bracket n, and having its motion limited bya projecting spur p. To the pivoted lever 'm I attach by means of a wing-nut r an arm 5carrying a ball or iioat t. As the flushing-stream causes the water in the tank to recede and fall below the ball t, as represented in Fig. l, the weight of the ball and connected parts will tilt the pivoted lever m, opening the water-way E, and allow a small stream of water to flow into the closet through the pipe C, and as the flushing-stream through the overflow-pipe ceases the valve will remain open until the rising water in the tank raises the ball t and closes the openingE. The duration of the flow through the small openingE is determined by the position of the ball t upon the pivoted lever m, thereby changing the position of the ball t with reference to the low-water line. If the ball is raised in the position shown in the accompanying drawings, the flow through the opening E will begin as soon as the receding water in the tank shall allow the ball to fall and open the valve m, and will continue while the water in the tank is reaching the low- A IOO Water line and rising from the 10W-Water line to a position at which it Will again raise the V ball t, close the opening E, and the nearerthe low-Water line the ball t is placed the shorter will be the duration of the stream through the opening E, and vice versa.

' In the iiushing-valve shown and described the high-Water line is determined by the floating ball B2 and the low-Water line is determined by the position of the ball e; but any of the known forms of valve can be used, having other means for starting and stopping the flow of the flushing-stream.

I do not herein claim, broadly, the combination of the flush-valve, siphon, air-vent, valve, and an afterloW-valve, as such have been heretofore used; but by the construetion and arrangement of the several operating parts I greatly simplify the apparatus zo and bring the same within a small compass.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination, with a flushing-tank, of the shell A', provided with a screw-threaded pipe C, and openings D and E,standpipe C', inverted cup C2, inclosing said stand-pipe and forming a siphon, bracket n, spur 79, formed on the shell A', bent lever m, .provided with a valve-disk, by which the opening E is closed, a float t, adj ustably connected With said bent lever, and a valve g, by which the openingD is closed, substantially as described.

Dated at /Vorcester, in the county of Vorcester and State of Massachusetts, this the 23d day of November, 1889.
