ABSTRACT:
A water-saving flushing device for a toilet tank is presented comprising a hollow casing and a rotatably attached pivot-plate secured inside said casing. A first pin pivotably secures an upper latch arm to said pivot-plate arm while a second pin pivotably secures a lower stop arm. A third pin is attached to the pivot plate. A float arm is attached to the third pin by means of a spring. The float arm rises or falls according to the water level in the toilet tank. To effectuate a partial flush, the flushing lever is pushed downward once. The travel of the flushing arm upward is limited by striking the upper latch arm. This limited path also limits the flapper valve to a partial opening only. When the mechanism is thus tripped, the latch arm rapidly recedes into the casing and a lower stop arm is forced outward to stop the downward travel of the flushing arm. As the water drains and then fills, the mechanism re-cocks itself. A second flushing motion in rapid succession to the first opens the flapper valve for a full flush when needed.
