Patent number: 5400445Abstract: 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.Type: GrantFiled: July 8, 1993Date of Patent: March 28, 1995Assignee: Kohler Co.Inventor: Douglas A. Hull

Patent number: 5301373Abstract: A flush mechanism for use with a toilet tank is disclosed. The mechanism permits selection between flushing cycles of two different time durations. The tank has a wall with an outlet therein and a valve member. The flush mechanism has a shaft linked at one end to the valve, a float slidably mounted on the shaft, and a cam pivotally connected to the shaft adjacent the float. The cam is rotatable between a short flush position wherein the float is allowed to assume a high position along the shaft and a long flush position wherein the cam member forces the float into a low position along the shaft.Type: GrantFiled: February 17, 1993Date of Patent: April 12, 1994Assignee: Kohler Co.Inventors: Douglas A. Hull, Randy O. Mesun
