Dual flush toilets

Claim 1

An improvement in the actuating mechanism of the flushing system in a dual flush type toilet having: a. a water storage tank for flushing the toilet; b. a fluid inlet; c. a float connected inlet valve which is actuated by the water level in the tank; d. an overflow tube which is operationally connected to the fluid outlet; e. a fluid outlet means; f. an outlet valve, including a vertically extended rod having a loop at its upper end, held in position above the outlet; g. a bracket, which can be mounted on and tightened to the overflow tube, an extension on the bracket, having a mount on which is set a vertically extended tube, which is aligned with a vertical hole in the mount and the bracket extension, forming a continous vertical hole running through the tube, mount and bracket extension, with cam surfaces on the mount at the base of the tube extending downward and in the direction of the overflow tube and on the other side of the mount a cut-out, exposing the vertical hole which extends through the tube, mount and bracket extension; h. a float, with a vertical tube through its center, extending above and below the float, mounted below the bracket, with that portion of the tube extending above the float, engaged slideably in the vertical hole which runs through the bracket extension, mount and vertical tube of the bracket; i. a flushing handle mounted on the outside of the water storage tank and operationally attached to a lever inside the tank, arranged so that when the flushing handle is depressed the lever rises and when the flushing handle is pulled up, the lever is forced down; j. a vertical wire link, with a horizontally positioned halfloop bend at its bottom, having a loop of flexible material (such as a rubber or neoprene band) stretched over the wire half-loop in such a manner as to close the open side of the wire half-loop, with two loops at the upper end of the vertical wire link, the first bend in the wire at the upper end forming a horizontal circular loop directly above and in a plane parallel to the plane of the wire half-loop at the bottom of the link and the second bend forming a rectangular loop whose plane is perpendicular to the planes of the half-loop at the bottom and the circular loop at the top of the link, with the vertical element of the link forming one of the sides of the rectangular loop which is positioned so that the end of the lever which is operationally connected to the flushing handle fits through the upper rectangular loop and the vertically extended tube and mounted on the bracket extension slide up through the space enclosed by the wire half-loop and the strands of flexible material which close the open side of the wire half-loop, permitting the vertically extended rod of the outlet valve to be slideably engaged through the horizontal circular loop of the wire link, the upper part of the hole in the vertically extended tube on the bracket and the hole in the vertical tube of the float, with the loop in the top of the vertically extended rod of the outlet valve positioned above the horizontal circular loop of the wire link; k. a means for selectively allowing the float to fall with tHe water level in the tank and a means for restraining the float from moving downward; and l. a means for transferring the downward force of the weight of the float to the outlet valve.
