Abstract
Abstract An improved toilet flush mechanism which upon actuation, permits either a limited amount of water to flow from the tank or the full amount of water to flow from the tank. The mechanism incorporates a pivotable member attached to a float arm which serves to close the opened tank valve as the float arm descends to limit the amount of water dispensed by the tank. When desired, the pivotable member is rotated away from engagement with the tank valve to permit the tank valve to remain open until a full tankful of water has been dispensed from the tank.

Claim 1
Independent Claim
157 words
A toilet flush tank mechanism which alternately provides means to permit a limited flush of the attached toilet or a full tank flush of an attached toilet, upon actuation of the mechanism, said tank fitted with a water supply valve controlled by a pivotable arm on which a float is fastened, which pivotable means is attached to the said pivotable float arm, which pivotable means in a first position serves to engage the outlet valve of the toilet tank mechanism, when the outlet valve is in the open position and the float arm has descended from its initial position, with further descent of the float arm serving to force said means to push the outlet valve into the closed position, in which the pivotable means may be rotated to a second position away from engagement with the outlet valve so as to permit the outlet valve to operate independently of the position of the pivotable float arm.
