Abstract: An apparatus for controlling the quantity of water flowing through a water outlet in the tank of a toilet comprising a timer including a rotatable output shaft, the timer being responsive to the angular rotation of the shaft from an initial position and operative to return the shaft to the initial position after a time duration corresponding to the amount of angular rotation of the shaft, a crank coupled to the shaft and being capable of rotating the shaft through a predetermined angle when a force is applied to it, a mounting assembly for mounting the timer to the tank, and a mechanical linkage coupled between the shaft and a lift rod in the tank for moving the lift rod a dimension such that a valve is unseated when the shaft is not in the initial position, and the valve is seated when the shaft is in the initial position, whereby when a force applied to the crank rotates the crank and hence the shaft through the predetermined angle the linkage is moved a dimension sufficient to unseat the valve from the wat

Abstract: An improved apparatus for controlling the quantity of water flowing through a water outlet in a toilet tank comprising a rotatable shaft having opposed first and second ends disposed through an opening in the front wall of the toilet tank, a crank mounted to the tank, connected to the first end and being capable of rotating the shaft through first and second angles when a force is applied to it, an arm connected to the second end, a box-like structure forming a chamber disposed in the tank and including first and second upwardly extending tubes forming first and second ports, respectively, an upwardly extending overflow tube, and a third port arranged to discharge water through the water outlet, the first tube having an axial dimension that is greater than the second tube, a first flapper valve hingedly connected to the overflow tube and being normally seated on the first port, the first valve being movable from a normally closed position to an open position, a second valve hingedly connected to the overflow
