Abstract: An incremental dual stage water-flush toilet has been developed to serve as a means of reducing to an absolute minimum the amount of water used in a water-flush type toilet. The toilet is comprised of a trapless toilet bowl with spring-loaded air valves over a pipe trap below floor level, and a water storage tank divided into a small and large compartments. An incremental flushing mechanism allows conventional type manual flushing of the toilet but will allow enough water to run into the bowl to cleanse the bowl and wash waste into the pipe trap below for interim retention. After multiple incremental flushings of that limited type, a major bowl flush containing enough water to clear the toilet bowl and also to wash all retained waste in the pipe trap into the available sewer line occurs. The sequence of smaller flushings with a larger flushing is again repeatable.

Abstract: A water saving apparatus for water conservation which is achieved by minimizing the amount of water required to flush a toilet effectively. A specially configured toilet bowl is combined with a small toilet tank which houses two independent flushing systems. They can be operated singularly, simultaneously or in sequence selectively, depending upon the degree and type of flushing deemed most appropriate by an operator for the occasion. The functions of expelling waste matter present in the toilet bowl and of washing the internal surface of the toilet bowl are separated and each function is performed by the flushing system deemed most effective to accomplish the task, and each task is completed with a minimum amount of water being required for this specific task. The operator alone selects which flushing mode is to be used and retains control of the proper flushing sequence. The operator then is the sole judge as to the extent of water saving that is justified.
