Abstract: A toilet lever assembly, including: (a) a sleeve dimensioned to pass through a toilet tank wall; (b) a rotatable post extending through the sleeve; (c) a toilet flush handle mounted to the end of the rotatable post that is positioned outside of the toilet tank; (d) a nut received onto the end of the sleeve that is positioned outside of the toilet tank; and (e) a lever housing mounted to the end of the post that is positioned inside of the toilet tank, the lever housing comprising: (i) an actuator for moving a toilet lever to cause a flush when the post is rotated, and (ii) a biasing mechanism for rotating the post back to a neutral position.

Abstract: A toilet flush valve having a tank ball and rod, with a pair of guide arms mounted on the overflow pipe. The guide arms are spaced apart vertically a distance greater than half the length of the tank ball rod. The upper guide arm is located a fraction of an inch below the top end of the rod; and has a hole through which the rod passes. The hole is only slightly larger in diameter than the rod, so that the latter slides freely through the guide arm, but without appreciable side play. The lower guide is spaced above the tank ball a distance sufficient to allow the tank ball to rise clear of the outlet seat, and has a hole with diameter approximately 2 to 2.5 times the diameter of the rod, so that the latter has sufficient side clearance to allow the ball to center itself on its seat. A knob is attached to the rod between the guide arms closely adjacent the lower guide arm.

Abstract: A water tank is disclosed suitable for connection to the bowl of a toilet device, the tank being provided with a flush valve actuated from the top end by an actuating device; an inlet valve of the up-closing type, connected to the water supply system; buoyant pulling mechanism for the inlet valve to carry the closing element onto the up-closing seat, to prevent the further entrance of water into the tank, when a predetermined level has been reached; and a rocking lever, mechanically connected to said flush valve actuating device, suitable to push the closing element of the inlet valve downwardly, against the buoyant mechanism and water pressure forcing it upwardly, so as to open the inlet passage of the valve, in order to replenish said tank, upon the flushing thereof, until said predetermined level is again reached.
