ABSTRACT:
A flush tank system includes an elongated tank supported at the opposite ends thereof by a pair of arcuate-shaped rockers which rest on the upper surfaces of a pair of support frames. The tank normally assumes an upright position with one of a pair of relatively slightly curved portions of each rocker resting on top of the support frames when the tank is empty and when the tank is being filled with a fluid such as water through an opening in the top thereof. The non-uniform cross-section of the tank causes the center of gravity of the water to shift laterally to a point at which the opposite rockers roll from the relatively slightly curved portion on which they are resting over a relatively greatly curved portion thereof to the other relatively slightly curved portion, thereby rapidly rotating the tank into a tipped position and pouring the water out of the tank opening. With the water discharged from the tank, the tank rotates back to the upright position where refilling of the tank with water may be resumed.
