ABSTRACT:
There is disclosed a mechanism for initiating and controlling a toilet: flush mechanism of the type which permits selection between two flush cycles which use different volumes of water end which, to do that, requires that the flush valve be lifted to either of two levels. Each of two rotating handles drives a shaft which rotates a flush lever arm. The shafts are concentric. One of flush lever arms has a longer crank portion than the other so that points on the lever portion move a greater vertical distance for a given angular rotation than move corresponding points on the flush lever arm with the shorter crank portion. A single blocking member limits the rotation of both flush lever arms to the same range of angular motion. Tabs on a bushing for the shafts supplement the blocking member by stopping rotation of the handle approximately when the blocking member contacts the flush lever arm driven by that handle.
