To all whom it may concern:

Be it known that I, FREDERICK A. Sonossow citizen of the United States, residing at lDetroit, county of WVayne, State of Michigan,have invented a certain new and useful Improvement in Flushing-Yalves and Controlling Mechanism, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a flushing valve and its controlling mechanism, shown in the accompanying drawings and more particularly described in the following specification andclaimsz One object of this invention is to eliminate the usual rubber ball with its attendant objectionable features and to provide a device of simple and inexpensive construction which includes a disk valve for closing the discharge outlet, linked to a manually controlled operating lever, from which is suspended a weight adapted to function automatically to return the valve to its seat following the manual operation of the valve tosecure the discharge of water from the tank,-said weight however, not becoming effective to close the valve until thewater is substantially discharged from the tank.-

Another feature of the invention is the variable weight employed to return the valve to its seat, consisting of a relatively small tank,-filled with water at all times suspended from one arm of the manually controlled operating lever, which when submerged in the water of the flushing tank loses itseifectiveness as a weight to control the action of the valve, but which upon the water being discharged from the tank through the operation of the manually controlled lever down to a level that will-admit ofthe small water filled tank again becoming operative as a weight serving to immediately cause the valve to return to its seat that the flushing tank may be again filled with water.

-With the foregoing and other objects in view which will hereafter appear, the invention resides in the combination and arrangement of parts and in the details of construction herein described and claimed,

it being understood however, that changes maybe made in the precise embodiment of the nventlon herein disclosed without departing from the spirit of the same.

In the drawings accompanying this specification and forming part thereof 'F gure 1 is a longitudinal vertical sectional view through a flushing tank with a portion of the tank broken away -showing the flushingvalve seated and the tank filled with water:.also the mechanism for con trolling theoperation of the valve.

Fig. 2 is a similar view showing the valve raised, and 'the water discharged down to a level which will cause the weight, servmg to automatically seat the valve, to function immediately.

Fig. 3 is a perspective view of the lever operating mechanism controlling the flushlng valve in the position shown in Fig. 2,? or as it would appear when the flushing valve is raised.

Fig. 4: is a perspective view of the valve, weight and lever operating mechanism as shown in Fig. 1,--or as it would appear with the valve seated.

Fig. 5 is a detail sectional view showing the adjustable screw for limiting the throw of the rocking lever and indicating in dotted lines the position of the arms and C when the valve is in open position.

Referring now to the letters of reference placed upon the drawings A, denotes a flushing tank. B, is a bracket secured to a ledge orother suitable device, in the side wall of the tank. .0, indicates a rocking lever, having projecting lu s D, D, pivoted to the bracket B.

,is a crank arm at one end of the lever to the end of which is secured a suitable chain or link connection F,-e xtending down through a pocket A, at one end of the tank,-fitted with a knob G, for the manual operation of the lever.

H, indicates a flushing valve of disk type, suspended from the opposite end of the rocking lever C, by a link I, having an eye J, loosely embracing the end of the lever.

'C, denotes an arm, provided with a series of perforations C projecting horizontally from the rocking lever C, when the latter is in the position shown in Figs. 2 and 3 of the drawings. I

K, indicates a relatively small tank or can (a p ed unde r ain c n tions t serve as an operating weight) suspended by a rod L, from the projecting arm C of the rocking lever,the rod being provided with a hook at the upper end that it may more readily enter one of the several apertures C provided for its reception. K, indicates an opening in the tank through which it may be filled with water, and K denotes a swinging cover for said opening to protect the water from spilling. 13, indicates an upstanding lug, preferably integral with the bracket B, in which'is supported an adjustable screw M, adapted to regulate the degree of throw of the rocking leverC.

Having indicated the several parts by reference letters, the construction and opera tion of the device will be readily understood.

For the purpose of this description, it will first be assumed that the valve is seated and the flushing tank filled with water as indicated in Fig. 1, the position of the valve operating mechanism being the same as shown in Fig. 4:. 4

To discharge the water from the tank, the flushing valve is raised by manually pulling down knob G, connected with the rocking lever C, thereby tilting the latterinto the position indicated in Figs. 2 and 3 of the drawings,-the degree of the throw bein regulated by the adjustment of the screw The can or tank K,-filled with water at all times,is also raised simultaneously with the valve but being submerged in the water of the tank will not function to return the valve to its seat until the water level in the flushing tank is lowered sufiiciently for the water filled can to become operative, whereupon it will cause the lever C, to rock thereby returning the valve H, to its seat.

It will now be seen that the closing of the flushing valve H, is entirely automatic and is contingent upon the discharge of water from the flushing tank, before the water filled tank K, can function to operate the rocking lever. The leverage due to the weight may be regulated by entering the end of the rod, from which the tank K is suspended,-in any one of the several apertures C provided in the arm O, of the rocking lever.

It will be apparent that when the flushing valve is manually raised, the arm of the rocking lever from which the valve is suspended, will rock from one side of the pivoted axis of the rocking lever to the opposite side of the pivoted axis of the rocking lever;-the weight of the valve itself thereby becoming effective to maintain the valve in its raised position until reversed through the action of the water filled tank acting as a weight.

I claim 1. In a device of the character described, a flushing tank, a rocking lever, a flushing tank valve suspended from the rocking lever the point of suspension of the flushing valve being carried from one side of the fulcrumed lever to the other by the rocking of said lever, and a water filled tank also suspended from the rocking lever adapted to be raised simultaneously with the lifting of the flush ing valve through the manual operation of the rocking lever but not enough to carry the point of attachment to the other side of the fulcrum, whereby upon the water being discharged from the flushing tank below the level of the suspended water tank the latter will function as-a weight to return the flushing valve to its seat.

2. In a device of the character described, a flushing tank, a rocking lever, means for manually operating the rocking lever, adjustable means for regulating the throw of the rocking lever, a flushing valve suspended from the rocking lever, the point of suspension of the flushing valve being carried from one side of the fulcrum of the lever to the other by the rocking of said lever, and a tank to be filled with water thatit may function as a weight also suspended from the rocking lever and adapted to be raised simultaneously with the lifting of the flushing valve through the manual operation of the rocking lever but not enough to carry the point of attachment to the other side of the fulcrum whereby upon the water being discharged from the flushing tank the weight of the water filled tank will become operative to seat the flushing valve.

3. In a device of the character described, a flushing tank, a rocking lever having a projecting arm provided with a plurality of holes, a tank to be filled with water, a link adapted to enter any of the several holes in the projecting arm of the lever for adjustably suspending said last named tank therefrom, a flushing valve also suspended from the rocking lever, the point of suspension of the flushing valve being carried from one side of the fulcrum of the lever to the other by the rocking of the said lever, said Water filled tank being adapted to be raised simultaneously with the lifting of the flushing valve through the manual operation of the rocking lever but not enough to carry the point of attachment to the other side of the fulcrum, and means for manually operating the rocking lever whereby the flushing valve and the water filled tank may be simultaneously raised so that the water filled tank may operate as a weight to return the flushing valve to its seat upon the discharge of water from the flushing tank.

4. In a device of the character described, a flushing tank, a rocking lever, a flushing valve suspended from the rocking lever, the point of suspension of the flushing valve being carried from one side of the fulcrum of the lever to the other by the rocking of the lever, a tank suspended from the rocking lever and adapted to be raised simultaneand a cover for closing the opening in the ously with the lifting of the flushing valve last named tank. 10 through the manual operation of the rock- In testimony whereof, I sign this specifiing lever but not enough to carry the point cation in the resence of two witnesses.
