WILLIAM J. KOENIG, OF BROOKLYN, NEW YORK.

FLUSHING-TANK VALVE.

Specification of Letters Patent.

Patented Nov. 6, 1917.

Application filed. July 24, 1916. Serial No. 110,849.

To all whom it may concern Be it known that 1, WILLIAM J. KOENIG, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Flushing-Tank Valves, of which the following is a description in such full, clear and exact terms as will enable any person skilled in the art to which it pertains to make and use the same.

My invention relates to a flushing tank valve device for closets and such places.

The object of the invention is to avoid the ball float, its valve and the other complicated parts of the commonly used flush tank mechanism.

The drawing represents a vertical section of the tank equipped with my invention.

10 is the tank which may be of either wood or metal, but which must be watertight on all of its sides, ton and bottom. 11 is the water inlet, and 12 is the outlet to the bowl.

14: is the valve which controls the discharge, the same being carried on a stem 15. This valve is seated by a spring 16. The stem 15 extends through a cylinder 17 which has a piston 18 fastened to it and its large ports 19 upon the piston, and small ports 20 below the same. 21 are tie-rods.

22 is a stuffing box for the rod 15, and 23 is an operating lever fulcrumed on a support 21'- and furnished with a chain or other device 25 for operating it manually.

The water under the usual or regular water piston enters the tank 10 by the pipe 11 and fills the same flowing into the cylinder 17 by both of the ports or series of ports 19 and 20. But the pressure on the piston 18 being balanced the spring 16 holds the valve 1 closed. Now, when the bowl is to be flushed the lever 23 is operated in the usual manner which results in lifting the valve 14 by the stem or rod 15 and compressing the spring 16. This also raises the piston 18, and the cylinder 17, throws water out of the ports 19 and sucks water into the ports 20.

The operator will now, according to the usual custom, release the chain 25 and then the spring 16 will act to return the valve 14 to its seat. This return is retarded by the water in the cylinder 17 under the piston 18 and the return cannot be accomplished until this water is exhausted through the ports 20; so that it will be apparent that a certain time interval is here forced to take place and that this time interval is the interval necessary for the discharge of the contents of the tank 10 through the outlet pipe 12. When this discharge is completed the valve 14: returns to its seat and the cycle of operation is complete.

Having thus described my invention what I claim is 1. In a flush tank the combination with the tank having a water inlet and a water outlet of a valve for the outlet, a stem for the valve, operating means for said stem, a spring to seat the valve, a cylinder through which the stem passes, a piston on the stem, said cylinder having ports above and below the piston for the purpose specified, and tie rods joiningtogether the seat of the valve and the cylinder structure, whereby the tank is strengthened and prevented from disruption by the strain of water pressure.

2. The combination with a flush tank having a closed top or lid and a water inlet, of an outlet fixture at the bottom of the tank, a valve within the tank controlling the outlet, a rod connected to the valve and extending through the top of the tank to permit opening the valve, a means for retarding the closing movement of the valve, said means connected to the top of the tank, and a tie-rod extending between said means and the said outlet fixture.

In testimony whereof I have hereunto signed my name in the presence of two witnesses.

WM. J. KOENIG.
