Abstract: YAn improved automatic flushing device for valve actuated toilets that is capable of being housed inside the toilet's water tank, out of the user's sight. The conventional water supply valve system is not altered and the flush valve assembly is actuated through floating means arranged in such a way that, depending on the water levels inside the tank, will urge the opening of the flush valve. When enough water has been drained out, the action of the floating means ceases and a tripping mechanism engages locking the floating means thereby preventing it from opening the flush valve again until the tripping mechanism is triggered in response to the users removing his or her weight from the toilet seat.

Abstract: An automatic weight operated toilet flushing device capable of being installed in conventional toilets with flush tanks. The device has one end of a long arm secured to the lower portion of the toilet seat assembly the seat and the other end engages a vertical actuating link which is pushed upwardly when the toilet user seats down. The vertical link engages the actuating lever mechanism which is pulled down when the user gets up and the conventional ball type valve is opened allowing the toilet bowl to be flushed.
