Abstract

A device for metering the flow of water into the tank and bowl of any currently known tank toilet and providing a positive shut-off of the flow. When the toilet handle is turned, a linkage rotates a cam to force a stopper from its seat thereby commencing water flow. Water flows through a flow channel to be directed by a flow nozzle past a water wheel imparting a rotation thereto. The water wheel is gearably linked to the cam thereby rotating the cam. When the cam has rotated to position a cam repeat over the stopper stem, the stopper is reseated by the pressure of the water and water flow ceases. The distribution of flowing water between tank and bowl can be changed by altering the structure of a bowl fill assembly. The bowl fill assembly and a tank fill tube are attached to the outlet by a right angle manifold. The amount of water flow permitted is a function of the number of cam notches and flow nozzle size.

Claims9

Dependent claims

A positive shut-off, metered water control system for use with flush toilet tanks comprising:

a housing assembly;
an inlet means attached to said housing assembly for mounting said control in the flush tank and providing a connection to a source of water under pressure;
an outlet on said housing assembly;
flow control means for alterably direction the flow of water between the toilet tank and the toilet bowl, said flow control means removably attached to said outlet;
stopper means mounted in an upper portion of said inlet means, said stopper means capable of movement between said sealed and open positions for shutting off or permitting water flow;
an air cushion, said air cushion affixed in said inlet means below said stopper means;
flow channel means within said housing assembly for directing the flow of water when said stopper means is in an open position;
start means for placing said metered water control system into operation;
an impeller rotatably mounted in a cavity portion of said flow channel means in said housing assembly between said inlet fitting means and said outlet;
cam means for controlling said positions of said stopper means, said cam means being linked to said start means;
and
linkage means for transferring the rotation of said impeller into a rotation of said cam means;
an input tube, said input tube removably attached at its lower end to said outlet on said housing assembly;
a manifold, said manifold having three extensions, a first extension attached to an upper end of said input tube, said first extension in the center of said manifold;
a second extension, said second extension to one side of and extending parallel to said first extension;
a third extension at a right angle to said first and second extensions;
a master tube, said master tube attached to said third extension;
a first step down means for reducing the flow of water to a toilet bowl, said first step down means slidably and removably received in the end of said master tube opposite said attachment to said third extensions;
and
a second step down means for further reducing the flow of water to a toilet bowl, said second step down means slidably and removably received in said first step down means.

17 more elements

A water flow control system for use with flush toilet tanks comprising:

a housing;
an inlet to said housing;
an outlet from said housing;
a flow channel between said inlet and said outlet;
a rotatable water wheel mounted in a wheel chamber in said flow channel;
a stopper slidably received in said inlet;
a start means for forcing said stopper into an open position thereby allowing water to flow;
a linkage means between said water wheel and said start means wherein said start means and said linkage means are disengagingly connected such that rotation of said start means is not imparted to said linkage means but rotation of said water wheel is imparted by said linkage means to said start means;
a flow distribution means for dividing the flow of water between a feed to the flush toilet's bowl and the toilet tank, said flow distribution means removably attached to said outlet;
an outlet tube, said outlet tube removably attached at one end to said outlet;
a manifold, said manifold having three extensions and being removably attached by a first of said three extensions to the end of said outlet tube opposite said outlet;
a tank fill tube, said tank fill tube removably attached to a second of said three extensions;
a bowl fill assembly removably attached to a third of said three extensions;
a bowl fill tube, said bowl fill tube providing the removable attachment to said third of three extensions;
a first flow control insert slidably and removably received in an end of said bowl fill tube opposite said attachment to said third of said three extensions and retained in said end by friction;
and
a second flow control insert slidably and removably received in an end of said first flow control insert and retained therein by friction.
