  • Patent number: 5181282
    Abstract: A semi-flush flapper valve apparatus is provided for use in a toilet and consists of a two position operable flush handle on the toilet tank. A main flapper valve has a bleeder valve pivotally mounted thereto. The operating handle is rotated in a first direction to operate the main flapper valve normally thereby causing a conventional full flush cycle in the toilet tank. The operating handle is rotated in a second direction to open the bleeder valve and operate the main flapper valve together thereby venting air from the main flapper valve so as to make the main flapper valve close faster causing a semi-flush cycle in the toilet tank.

  • Patent number: 5070547
    Abstract: A dual handle semi-flush retrofit kit is provided and consists of a water releasable reservoir cup the weight of which varies the effective buoyancy of the flapper flush valve, connected between the flapper flush valve and double flush handles on a toilet tank, such that if one handle is operated the toilet tank is fully flushed in the conventional way. If the other handle is operated the toilet tank is only half emptied thereby saving many gallons of water. This dual handle semi-flush retrofit kit can be easily installed by the do-it-yourself home owner.

Primarily, it consists of two main floats and each are controlled by a right and left rotation of a toilet tank operator's handle. One float of the combination controls a pre-determined lower water level in the tank, and the other controls a second and higher level of water in the tank that may be discharged as desired.

  • Patent number: 4910812
    Abstract: A semi-flush valve mechanism in a toilet tank is provided with a two way flush operating handle. If the handle is pressed downward the toilet tank is flushed fully in the conventional way. If the handle is pressed upwardly the toilet tank is only half emptied in a semi-flush. A pivotally extended vane on a tilted valve assembly will receive a water stream from a refill tube to sooner help restore the toilet tank valve assembly to its closed upright position causing the semi-flush.
