  • Patent number: 4007499
    Abstract: Control apparatus used in connection with commodes automatically moves a trip lever for flushing the commode and includes a member adapted to be connected to the trip lever for moving between an initial position and a flushing position to cause the trip lever to raise a drain valve to its open position. A spring moves the member to its flushing position, and a person-operated device causes energy to be stored in the spring and releases subsequently the energy from the spring to move the member toward its flushing position. A latching device connected to the member connects releasably the member and the trip member for moving it and the valve against the force of water pressure acting on the valve until the water pressure equals the force applied by the spring after sufficient water discharge.
