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. These parts and apertures prevent waste from smearing the seat, rim, and back of the bowl. Water valves (178) and (183) respectively respond to hand plungers 29 and 31 so that the toilet also works during an electric power outage. The toilet is programmable and more user friendly.

[ We claim:] [6.]6. A rotatable flap and cup combination for flushing a toilet bowl free of solid waste so said cup can form a clean main water seal in said bowl, comprising:(a) means for rinsing said bowl with clean water,(b) a rotatable flap being positioned within a waste passageway leading to a sewer pipe,(c) said rotatable flap being rotatably closed against a cylindrically-shaped bottom outlet of said bowl,(d) said flap being rotatably open downward and rearward from said bottom outlet,(e) a rotatable cup being within said waste passageway,(f) said rotatable cup being rotatably closed to surround said closed flap and said bottom outlet,(g) said cup being rotatably open downward and rearward from said bottom outlet and said closed flap,(h) said flap, when normally closed, being closely applied to said bottom outlet,(i) said cup, when normally closed, surrounding said closed flap and said bottom outlet of said bowl with water held within said cup to form a main water seal between said sewer pipe and said bowl,(j) springy flap means which enable said closed flap to retain solid waste in said bowl so as to permit rinse water in said bowl slowly to seep from said bowl to fill said closed cup,(k) means for opening and closing said flap and cup so as to permit solid waste in said bowl to flush freely and cleanly through said waste passageway into said sewer pipe without entering said cup upon the actuation thereof to open said flap and cup to an open position, and(l) so as to permit said clean rinse water to accumulate in said cup and bottom outlet when said flap and cup is in a close position, wherein said accumulated clean water surrounds said closed flap and bottom outlet so as to form a clean main water seal to prevent sewer gases from rising into said bowl.
