Abstract
Abstract An improvement is described for a tank type toilet flushing system. A positive coupling is provided between the flushing handle and the tank emptying flushing valve including a rigid flush control rod. This permits the flush to be terminated at will and before the flush tank is completely emptied. The flush control rod has a bent, length adjusting section, and a bent section for removably mounting a float.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
165 words
In a flush tank having a movably mounted flush valve in the bottom which is normally moved to an open position by a handle operated means and which is kept open by the liquid in the tank and which also closes as a result of the flow of the liquid from the tank, the improvement comprising a relatively rigid coupling member operatively connecting the handle to the flush valve whereby said flush valve may also be closed by the said handle at any time during the flushing action and while the tank still contains a substantial volume of liquid, said coupling member comprising a relatively rigid rod with means for connecting opposite ends to said lever and to said flush valve and being capable of transmitting both upward opening and downward closing force to said flush valve, and said rod comprising a bendable metallic rod having a bent length adjusting and a second bent section, and a float member mounted in said second bent section.
