Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
227 words
A semi-flush valve mechanism adapted for use in a toilet tank that includes a refill tube for providing sealing water and a tilting valve assembly of the type having a housing defining a reservoir chamber, a pivot bracket connecting the housing a port to the tank and providing communication between the tank and reservoir chamber, and an overflow tube, said valve mechanism comprising: (a) a vane adapted to be pivotally hinged to a side of the housing so that said vane can be pivoted into an extended position and a retracted position; (b) a first means operating handle adapted to be pivotally mounted to the toilet tank so that said handle can rotate clockwise and counterclockwise; (c) a first means coupled to said handle for lifting the valve assembly to an open tilted position and for keeping said vane in the retracted position when said handle is rotated counter clockwise causing a conventional full flush cycle in the tank; and (d) means coupled to said handle for lifting the valve assembly to the open tilted position and for simultaneously moving said vane to the extended position when said handle is rotated clockwise allowing a water stream from the refill tube to strike said vane and apply pressure thereto tending to restore the valve assembly to a closed upright position sooner causing a semi-flush cycle in the tank.
Claim 2
Dependent Claim

A semi-flush valve mechanism adapted for use in a toilet tank that includes a refill tube for providing sealing water and a tilting valve assembly of the type having a housing defining a reservoir chamber, a pivot bracket connecting the housing a port to the tank and providing communication between the tank and reservoir chamber, and an overflow tube, said valve mechanism comprising: (a) a vane adapted to be pivotally hinged to a side of the housing so that said vane can be pivoted into an extended position and a retracted position; (b) a first means operating handle adapted to be pivotally mounted to the toilet tank so that said handle can rotate clockwise and counterclockwise; (c) a first means coupled to said handle for lifting the valve assembly to an open tilted position and for keeping said vane in the retracted position when said handle is rotated counter clockwise causing a conventional full flush cycle in the tank; and (d) means coupled to said handle for lifting the valve assembly to the open tilted position and for simultaneously moving said vane to the extended position when said handle is rotated clockwise allowing a water stream from the refill tube to strike said vane and apply pressure thereto tending to restore the valve assembly to a closed upright position sooner causing a semi-flush cycle in the tank.
Claim 3
Dependent Claim
93 words
A semi flush valve mechanism as recited in claim 1, wherein said first means includes: (a) a first lift arm coupled to said handle so that said first lift arm will be lifted in a counter clockwise direction only when said handle is rotated counter clockwise; and (b) a first flexible lanyard connected between an end of said first lift arm and said vane so that said vane will be kept in the retracted position when the valve assembly is being tilted in the open position when said handle is rotated counter clockwise.
Claim 4
Dependent Claim
175 words
A semi-flush valve mechanism as recited in claim 2, wherein said second means includes: (a) a rest member adapted to be mounted to the tank; (b) a second lift arm having a short section coupled to said handle and pivotally connected to a first end of a long section so that when said handle is rotated clockwise it will rotate said short section clockwise which in turn causes said long section to bear against said rest member at a point along said long section spaced from said first end and thus rotate about the pivot creating an upward counter clockwise pull at a free end of said long section; (c) a lever connected at a right angle to said hinge on said vane; and (d) a second flexible lanyard connected between the free end of said long section of said second lift arm and said lever so that said vane will be simultaneously moved to the extended position while the valve assembly is being tilted into the open position when said handle is rotated clockwise.
Claim 5
Dependent Claim
135 words
A semi-flush valve mechanism as recited in claim 3, further comprising: (a) an aperture adapted to extend through a side of the overflow tube; (b) a leg with a float adapted to be pivotally-attached to side of the overflow tube to seal off said aperture only when said overflow tube is in a vertical position; and (c) a third flexible lanyard connected between said leg and said vane so that when said vane is moved to the extended position said leg will be simultaneously pulled forward by said third flexible lanyard so as to expose said aperture to allow more water to enter the port providing additional sealing water during the semi-flush cycle, whereby said aperture will be sealed when said float returns to its vertical position by the returning water level in the tank.
