Apparatus for selectively dispensing either of two different volumes of water from a water closet comprises a mechanism for latching a valving member (e.g. a flapper valve) in a position just short of a threshold position at which it would normally “flip”to its full flush position, and for unlatching such member, after a predetermined quantity of water has flowed from the tank, to allow it to return to its closed (sealing) position.

Toilet flushing apparatus for selectively dispenaing either of two different volumes of water through an outlet formed in the base of a water closet, said water closet including a movably mounted valving member for selectively closing and opening such outlet to respectivelv prevent and allow the passage of water therethrough, said apparatus comprising: (a) manually operable means for applying a displacement force to said valving member to selectively move said member from a rest position, in which it closes said outlet, to either (i) a first position which is so far displaced from the outlet that said valving member will not return to its rest position, notwithstanding removal of such displacement force, until substantially all the water in the water closet passes through the outlet, or (ii) a second position directly above and closely spaced from the outlet in which said valving member will immediately return to its rest position in respnse to removal to such displacement force, said manually operable means comprising a movably mounted lever arm operatively coupled to said valving member, and handle means for selectively moving said lever arm upwardly from a rest position through first or second different displacement ranges to cause said valving member to move from its rest position to either said its first or second position, respectively; and (b) latching means for selectively latching said valving menber in said second position until a predetermined volume of water has passed throuch the outlet, and for unlatching said member thereafter to allow said member to return to its rest position.
