ABSTRACT:
A toilet flush mechanism conserves water by offering a choice made by the direction of rotation of the flushing handle of either actuating a first lever initiating the discharge of a full tank of water or actuating a second lever initiating the discharge of a predetermined fraction of the water in the full tank, herein designated a mini-flush. A flapper valve controlling the discharge of water from the tank is opened by the actuation of either of the levers, is permitted to close in conventional fashion when the tank is empty upon first lever actuation and is closed by a downward thrust of a striker upon second lever actuation. A water level responsive device including a second float triggers the striker and acts independently of the ballcock valve and float which maintains the full level of water in the conventional manner. A control assembly, which normally locks the water level responsive device thereby preventing operation of the latter during a full tank flush, releases the water level responsive device for triggering the striker upon actuation of the second lever and maintains the released condition until the tank refills after the mini-flush. The first and second levers are pivotally mounted on the interior of the front wall of the tank in the handle region and all other components are supported by a housing secured to the overflow tube of the tank. Adjustability in the water level responsive device permits varying the volume of water discharged in the mini-flush.
