Abstract: A multiple variable flush storage tank toilet has been developed as preferred state-of-the-art to improve the means of reducing the amount of water used in a water flush type toilet. The improved mechanism within the toilet storage tank relies on a partitioned smaller and larger compartmented space in accordance with that state-of-the-art. The variable means of flushing to obtain a multiplicity of smaller water flushes plus a larger water flush has been obtained by use of “V”-indented polygons. The mechanism for flushing is operated by using a conventional exterior tank handle and is adaptable for a variety of polygons. All functions of the mechanism are simplified beyond that of the current conventional toilet. The variety o flushings are duplicated as use of the toilet is continued.

Abstract: A toilet structure having lower and upper water tanks, the latter being fixed on the former, a lower outlet on the bottom of the lower water tank for supplying water from the lower tank to a whirling water feed outlet in an associated nightstool, and an upper outlet on the bottom of the upper tank for supplying water from the upper water tank to a ring of holes formed in an upper periphery of the nightstool. When a rotatable knob is turned in a first direction, a small amount of flushing water is discharged from the lower tank through the lower outlet to flush urine from the nightstool. When the knob is turned in a second direction, both the water tanks discharge water simultaneously for flushing nightsoil from the nightstool. Accordingly, water consumption is reduced.

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 closet (10) for conserving water which has a siphon jet (30) in the bowl (12) for initiating evacuation of the contents of the bowl through the trap (26), and a flush water storage tank (14) that includes chambers (68) and (72) through which water can flow in measured quantities, first to the siphon jet for initiating the siphon action, and second, to the bowl (12) for rinse purposes in a timed-delay action so that substantially no mixing of the rinse water with the contents of the bowl occurs.

Abstract: A fluid discharge regulating device to be used for conserving water in the toilet tanks of bathroom toilets. The device includes partitions that divide the toilet tank into three consecutively arranged compartments, each compartment providing fluid communication with other compartments, either directly or indirectly, through portholes in each partition. Each porthole opening is adjustable to control the rate of fluid flow into the second or middle compartment in order to maintain constant the amount of water used during a single flush. The volume of fluid reaching the toilet bowl can be increased beyond the preset level by holding down an adjustable handle which is connected to the flushing mechanism.

Abstract: A combination wash basin and toilet water conservation system having at least one wash basin and a toilet having a water tank. The water tank has a fresh water chamber and a gray water chamber. A first outlet connects the gray water chamber with the bowl of the toilet and a flapper valve closes this outlet. A second outlet connects the fresh water chamber and the gray water chamber and a buoyant valve closes this outlet. Piping connects the drain of the wash basin to the gray water chamber. Piping also connects a source of fresh water to the fresh water chamber. A hand lever on the outside of the toilet operates a lever arm within the water tank which when it is raised upwardly actuates structure causing the buoyant valve to rise thereby letting fresh water into the gray water tank. Structure is also actuated in the gray water tank when the lever arm raises upwardly and this structure opens the flapper valve to release water from the gray water chamber into the toilet bowl for flushing thereof.
