Abstract
Abstract This device consists primarily of a U-shaped member which is secured to the lift lever and lift rod by bolt fastener means, the structure being such, that when the lift lever is actuated by the attached lever handle, the valve will open and a discharge of water will pass from the tank, and with an upward pressure on the lever handle immediately following the opening of the valve, the valve will close and prevent further discharging of water in reserve within the tank.
