Abstract: A gravity drop-toilet uses main water via electronically programmed valves to rinse separate areas of a bowl (71) in sequence via appropriately located and pointing jet orifices (136, 138,140) with about 70% less water than siphon toilets. Electronically timed valve (180) hydraulically causes a pair of bellows (110) to compress and expand and thereby reversibly pivot a mechanical linkage to retain waste in the bowl and drop waste via a vertical waste passageway into a sewer pipe (30). The linkage comprises a transfer arm (118) that pivots a rotating arm of a cup (128) and flap actuating arm (104) to pivot a springy plate (78) upward against a dimple (80) formed on under the side of the flap (30) which thereby aligns itself against the bottom edge (74) of the bowl (71). A urine version of this mechanism uses apertures (174, 175) that they enclose combine to center defecating sitters over a cylinder outlet (48) of the bowl.

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 dual flush mechanism equipped with a two independent flush valves which are each separately controlled by a separate spring loaded button. The flush valves are at different heights in the toilet tank such that actuation of the upper flush valve, by pressing a first button on top of the tank, will produce a short flush, while pressing of the second button will actuate the lower flush valve to produce a long flush. Pivot rods are pivotably supported on a common axis below the first and second buttons. The upper end of each pivot rod is coupled through a spring to its respective push button on top of the tank. The opposite ends of the pivot rods are coupled respectively through a chain to the upper and lower flush valves. Pressing the first button exerts a downward force through the spring on the first pivot rod to raise the opposite end thereof which in turn raises the upper flush valve. Pushing the second button actuates the second pivot rod in the same manner to raise the lower flush valve.
