Auxiliary flush valve mechanism for toilet tanks

Claim 1

A toilet tank flush valve operating mechanism for lifting the valve by a lever adapted for angular movement, a rotatable spindle having said lever fixedly mounted on the inner end thereof, an operating handle fixedly mounted on said spindle at the outer end thereof, upper and lower stops adapted to establish a range of angular movement, said lever being controlled relative to its range of angular movement, and wherein the improvement consists of a second lever adapted to coact with said first lever, said second lever consisting of a rod bent into a U shape, the corners being substantially sharply bent, and comprising a relatively long leg, forming a second spindle rotatably and axially mounted within said first spindle, and extending a relatively short distance beyond the outer end thereof, and a shorter leg passing under said first mentioned lever and being in close proximity to the under side thereof, and a second operating handle fixedly mounted on the outer projecting end of said second spindle, a boss at the remote end of said upper stop having a threaded aperture, an adjusting screw engaging the aperture of said boss, and being so positioned as to permit the range of travel of said second lever to be preset, thereby permitting control and restriction of said valve up to a point below the level of buoyancy thereof whereby the amount of discharge of water from a tank can be regulated.
