Alternate toilet bowl flush apparatus

Claim 1

A toilet bowl tank designed to alternately discharge the full or a partial amount of water in the tank, said tank fitted with a discharge outlet in the bottom wall of the tank and fitted with a ball-cock valve that rests, in a first position, on the rim of the discharge outlet of the tank, said tank fitted with a sleeve that rests, in a first position, on the bottom wall of the tank in vertical orientation about the ball-cock valve and discharge outlet, with first lifting means linked to a handle mounted on an external wall of the tank so as to lift the ball-cock valve to a second position, said second position of the ball-cock valve being above the discharge outlet so that the ball-cock valve is clear of engagement with the rim of the discharge outlet, and with a second lifting means linked to said handle so as to lift the sleeve to a second position, said second position of the sleeve being clear of engagement with the tank bottom wall surrounding the discharge unit, said first and second lifting means being independently linked by means to the handle such that manual operation of the handle alternately actuates only one of the said lifting means in response to a given direction of movement of said handle, with said first lifting means fastened to the ball-cock valve by a flexible tension member that passes freely through a hole in a member fixed to the top of the sleeve, and with a projection fastened to the tension member above the sleeve, said projection of a larger size than the said hole so that lifting of the sleeve by the second lifting means serves to also lift the said projection and the attached ball-cock valve.
