Abstract:
In a water flush waste disposal system that comprises a gravity flow, water-flush capability drawn from a refillable water holding tank, and equipped with a water/waste collection bowl and bowl trap, having a first conduit means to pass finite amounts of water from the tank to the bowl, a second conduit means for passing water-diluted waste from the bowl trap to the sewage system, and a first valving means for passing diluted waste from said bowl to interim storage within the bowl trap, and having a second valving means to clear trapped waste from said bowl trap, the system further being adapted for variable water volume dispensing from the holding tank, the improvement comprising:(a) a water holding tank provided with an internal vertical partition wall dividing the holding tank into a larger first liquid storage compartment and a second, but substantially smaller, liquid storage compartment;(b) a waste trap zone disposed below the bowl in said second conduit and in fluid communication with said bowl adapted for retaining diluted waste materials passing to it from each valving means from water flow from the said smaller compartment;(c) a vertical-aligned, polygonal plate having an axial bore hole, and mounted within a top section of said holding tank being adapted to rotate axially in incremental steps, with each step being associated with the release of liquid held in said smaller tank compartment, said plate also being provided along the periphery with a plurality of spaced-apart recesses, defining arrow-like point recesses, all points being oriented to point in one tangential direction on the plate;(d) an external knob mounted on the outer surface of the holding tank, and being adapted to operatively interact with said polygonal plate and to shift said plate rotationally upon each activation of the external knob;(e) a flush controlled linear member serving as the mechanism to translate knob actuation to the rotatable plate, which member has a first proximal rigid segment and a pivotally attached second distal rigid segment;(f) a first linking means operatively interconnected between a point on the second segment and the first valving means which is provided proximal to the bottom section of said first compartment, whereby a rotational step move of said plate opens said first smaller compartment to said bowl permitting liquid flow therefrom;(g) a second linking means operatively interconnected between a point on the first segment and a second valving means cover which is provided proximal to the bottom section of said second compartment, whereby a rotational shift of said plate opens said larger compartment to said bowl permitting water liquid flow therefrom;(h) a pair of spaced apart, upstanding support members adapted to receive at their upper longitudinal ends, a horizontally oriented support pin, which pin engages the axial bore of said polygonal plate;(i) a first L-shaped lever member pivotally pinned to a point intermediate the longitudinal ends of the first proximal segment of the control member and having its distal longitudinal end adapted to tangentially engage sequentially with the plurality of recesses arrayed on the plate periphery, and then to disconnect;(j) a second L-shaped member pivotally pinned coincident with the axis of the polygonal plate, and adapted to limit the upward travel of the second distal segment of the linear member when it starts to activate the anchored second linking means which serves to void the second water storage compartment.
