T LZZ whom, it may concern: A

Be it known that I, CHARLES HoRA'rIo SHEPHERD, of the city of New York, borough of Manhattan, in the county of New York and Improved Lock for Flushing-Valves, of which the following is a full, clear, and exact de- .scription.

The invention relates to locks for flushingvalves such as shown and described in the Letters Patent of the United States No. 594,709, granted to me on November 30, 1897.

The object of the present invention is to provide certain new and useful improvements in flushing-valve locks whereby the lock can be readily applied to any kind of iiushingtank and setto lock the `raised iiushing-valve lever in position until the tank is empty and the lever is released by the oat-lever unlocking the lock.

The invention consists vof novel features and parts and combinations of the same, as will be described hereinafter and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi- Vcate corresponding parts in all the figures.

Figure l is a sectional side elevation of a kflushing-tank provided with the improvement. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. l, and Fig. 3 is an enlarged cross-section'of the improvement on the line 3 43 of Fig. 1.

The flushing-tank A is provided with the usual water-inlet valve B, controlled by a float-lever C, and at the bottom of the tank is an outlet-pipe D, normally closed by a 'flushing-valve E, connected to a lever F, provided With a pull cord or chain G under the` control of the user of the closet for liftingk lmounted to turn in suitable bearings in a casing J, clamped or otherwise fastened to ithe upper edge of one'of the'sides of the tank, as shown.

State of New York, have invented a new and On the shaft-I within the casing is secured a toothed Wheel K, engaged by a pawl L, fulcruined at L in the casing and having an eX- tension Lz-projecting through an opening` in one side of the casing J. The outer end of Vthe extension L2 is connected with one end of a chain or rope N, hanging in the tank A, the other end being fastened to the side of the tank opposite that on which the casing is clamped, so that the chain is in the path of the float-lever C, and the latter exerts a pressure on the chain when swinging into a lowermost position upon emptying the tank of its contents. A spring O presses on the pawl L to hold the same normally in mesh with the toothed wheel and keep the latter locked against rotation in the direction of the arrow a. A portion K of the wheel K is without teeth, and a iixed pin P extends into this portion to limit the turning motion of the wheel K and the swinging motion of the arm H.

When theseveral parts are in the position shown in the drawings and the user pulls the chain G to impart a swinging motion to the lever F, then the valve E is lifted off its seat and the water runs out of the tank through the pipe D to flush the bowl. The lever F in swinging upward at its inner end carries along the arm H, whichturns the shaft I and wheel K in the inverse direction of the arrow a', so that the pawl L glides over the teeth.,

As soon as the swinging motion of the lever F ceases, the Vpawl L, by the action of the spring O,V drops into a corresponding tooth of the Wheel K to prevent the same from rotating in the direction of the arrow a', thus holding the Wheel K, the arm H, and the lever F in a locked position no matter how much or how little the valve E is unseated by more or less pull on the lever F. Thus the valve E cannot return to its seat, and the water runs out of the tank even if the operator immediately .releases the pull rope or chain G after having given but a short swinging motion to the lever F. As the tank empties the float-lever C swings downward and inally opens the valve at the time the lever in its downward IOO movement comes in Contact with the ehain N and pulls downward 011 the same to swing the pawl L out of mesh with the toothed wheel K. The latter is thus released or unlocked, and the arm Il, with the overbalaneed inner end of the lever F on the top of the arm, swing downward by their weight until the valve E is again seated and further outllow from the tank stopped. The turning of the wheel K is lilnited by its stop-pin l), as shown in Fig. 3. The tank new fills with water through the open valve B until the float on rising causes a shutting oft of the supply. The several parts are then again in anormal position, the tank being Illled with water and ready 'for a second flushing.

New it is evident that no matter how slight a pull is given to the eliain or rope G the lever is looked in platee by the leek until a proper Ilushinghas been accomplished. The lock is then again unlocked by the aetien ol.' the float-lever, as described.

Having thus fully described my invention, I elaim as new and desire to secure by Letters Patent* A loek for llushing-Valves, comprising a lever-arm arranged to connection with a ilushing-Valve lever, a shaft Carrying the said arm, a toothed wheel on the said shaf t, and a spring-pressed levenpawl for engaging the said wheel and locking the latter against r0- tation in one direction, the said lever-pawl being adapted to be actuated from the iloatlever of the flushing-tank to unlock the wheel and the lever-arm, substantially as shown and described.
