Application led December 21, 1907. Serial No. 407,580.

To all whom it 'may concern.:

Be it known that I, FREDERICK A. SoHossow, citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Flushing-Tanks for Closets, 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 vit pertains to make and use the same, reference bein had to the accom anying drawings, whic form a part o this specification.

My invention relates to an improvement in flushing tanks for closets shown in the accompanying drawings and more particularly pointed out in the claims.

The object of my invention is an improvement in the general construction and arran ement of the parts particularly of the mec ianism controlling the'opening and closing of the inlet and outlet Valves.

One of the features of this invention is a fioat so constructed and arranged that it serves to support a weighted lever with which the inlet valve is connected, holding the valve open until the tank has lilled,the float itself then iills with water permitting the weighted lever to descend, and this action forces the valve to its seat and cuts off the supply of water to the tank.

A\nother feature is the means employed to hold the valve open, after being raised maiiually, until the water in the tank has been discharged. As the water passes from the tank, that in the float above referred to is also discharged. This action ermits the weighted lever to operate, tripping the outlet valve which returns to its seat by gravity g-opening at the same time the inlet valve admitting water again to the tank.

Another feat-ure of the invention is the means employed to regulate the volume of the afterlow or seal.

Other improvements and advantages will hereafter appeal'.

In the drawings Figure l is a longitudinal central sectional view through the tank, showing it filled with water, the inlet valve being closed. Fig. 2 is a cross-sectional view through the tank, showing in section an adjustable collar on the overflow ipe by means of which the volume of the a terow or seal is regulated. Fig..3 is a similar sectional view to that shown in Fig. 1, the water, however, having been discharged from the tank, the inlet valve being shown in the act of opening, while the discharge valve, in its raised position, is about to be trip ed or released .by the action of the tilting ever ;--showing also in dotted lines the position of the parts when the outlet valve 1s closed and the inlet 'valve open. Fig. 4 is a perspective view of a detail ofv construction, showing the discharge valve, the

osition of the valve stem and the lever as it appears when the tank is filled with water;-and in dotted lines the position of the valve, its stem and the arm on the rocking lever as it would appear when about to release the valve that 1t may return to its seat.

Referring now to the4 letters of reference shown upon the drawings: A denotes the tank, A a lining of sheet metal.

B is an inlet valve of the plunger type, and C is the outlet valve, C its stem having an enlarged portion c inclosed within the upstanding collar c of the valve.

c2 is a screw-threaded cap engaging the collar and loosely sleeved upon the valve stem C', confining the enlarged portion c of the stem within.

D is a lever pivoted to the tank to which the valve stem C is engaged.

1) is a rod connected with the lever and provided with a thumb piece d for manually actuating it.

E is a tilting lever pivoted at e to a suitable supporting bracket E attached to the overflow pipe.

F is a weight or water bucket mounted on one end of the lever designed Vto contain water at all times. G is a fioat and Water bucketmounted on the other arm of the lever E, beneath which is supported the lixed weight it. being of less relative weight, however, than that of the Water bucket l" when filled.

G2 is a Siphon supported within the water' bucket G its longer leg extending through the bottoni of the bucket into the tank chamber A.

H, H and H2 are linked connections between the tilting lever E and the inlet Valve B, and H3 is a rod pivoted to the body of the valve and en agin the link H', the action being such t iat w ien the lever E tilts the valve B is either opened or closed dependent upon the position of the tilting lever.

Projecting from the bracket E is a sleeve E2 embracing the stem C which at this point is provlded with an enlarged portion or shoulder C3. The sleeve portion E2 is cut away on one side to rovide a platform E3 upon which rests the's oulder C3 of the valve stem when in its elevated or open position as shown in Fig. 3.

Projecting from a depending arm on the tilting lever E is a trip ing arm-E4 designed to encounter the cap 2 on the outlet valve C, upon the movement of the lever,-where by the enlarged portion C3 `of the Valve stem may be forced from its supporting platform E3, permitting the valveto descend to its seat. e is a stop lu from the bracket projecting downwardly and is designed to limit the movement of the tilting lever E by the arm E4 encountering the lug.

I is an overflow pipe having a discharge connection with the valve fitting C beneath its seat. The upper open end of the pipe is provided with a collar screw-threaded thereon by means of which the altitude of the opening into the pipe may be increased and decreased at will to provide for a greater or less volume of after-fill.

Having indicated the several parts by reference letters upon the drawings, I will now describe the operation of the device.

The water bucket F is first filled through the opening provided at its top z-the weight of the water bucket vF when filled being greater than the weight G. The lever E is thus caused to tilt which action serves to open the inlet valve B permitting the water to enter and fill the tank. As the water rises in the tank it gradually enters the water bucket G by Way of the Siphon G2. The water, however, does not rise in the bucket G as rapidly as it does in the tank due to the restricted opening of the siphon.

Upon the water mounting 1n the tank until itreaches the level of the to of the bucket G it flows over the top f illlng thevbucket thereby destroying its action as a ioat, the purpose of which 1n conjunction with the action of the bucket F has been to hold open the inlet valve until the tank has filled with water. The action of the bucket F having been neutralized by the filling of the bucket G and the water rising in the tank, the weight G becomes operative serving to tilt the lever E in the opposite direction thereby forcing the inlet valve to its seat thus cutting 0H" the supply of water to the tank.

To release the water from the tank, the outlet valve C is raised by manually actuating the lifting rod D as in the usual way.

U on raising the valve stem C which is slightly incllned, the enlarged portion C3 swings over the shoulder E3 of the bracket E which serves to support the valve in its open position permitting the discharge of water from the tank. As the tank is gradually emptied the water contained within the bucket or float G passes out by way of This is so timed due to the bucket G is discharged at the time the tank is emptied. This action causes the lever E to tilt due to the action of the superior Weight of the bucket F, and thus the outlet valve C is vclosed by forcing it from its supporting platform from which it descends to lts seat by gravity as before explained. The tilting of the lever E has also served to open the inlet Valve B permitting the water to enter the tank as before, the action and operation of the several parts being again repeated as previously explained. As the water mounts in the tank it entersthe top of the overow pipe; the altitude of which may be increased and decreased by adjusting the collar, thus providing the after-fill or water seal required following the discharge of the closet. In place of the Siphon in the float water bucket, a restricted opening may be provided in the bottom, the action of which would be practically the same so far as the result is concerned.

Having thus described my invention, what Iclaim is:

. 1. In a flushingdevice, a tank having an inlet and an outlet, an operating lever, a valve for said outlet having its stem connected to said lever, a tilting lever mounted in the tank, a variable float mounted at one end of the lever, and a fluid chamber adapted to serve as a weight whose function is lessened as a weight by the rising of the Water in the tank, said tilting lever having engagement with the stem of said valve when the lever moves in one direction to effect a lowering of the valve into engagement with the outlet.
