A spray head assembly is made from a very few number of injection molded parts. Preferably a pair of elongated housing shells fit together in face-to-face confrontation, with a spring biased actuator arm or control lever pivotally mounted between them. The lever has a metal shaft extending therefrom, which passes through a flexible cone in a rubber bulkhead to maintain a waterproof seal. In front of the bulkhead is a solid plastic plate having mounted therein a reciprocally slidable member controlled by the lever. In one embodiment, the sliding member contains a generally triangular or tapered opening or openings having a sector of a circle for a base. Depending upon the position of the slide, the opening moves up or down to open or close a water passageway through the spray head. The sliding member first presents the smaller sectors of the opening or openings to an associated sealing ring to minimize the abruptness of any change in discontinuity of water flow at the edge of the opening. In another embodiment, a stainless steel plate is countersunk in or affixed to the back of the sliding member to reduce wear. The spray head delivers water in a generally rectangular spray pattern.

The sliding member contains a generally triangular or tapered opening having a sector of a circle for a base. Depending upon the position of the slide, the opening moves up or down to open or close a water passageway through the spray head. The sliding member first presents the apex of the opening to an associated sealing ring to minimize the abruptness of any change in discontinuity of water flow at the edge of the opening. The spray head delivers water from a generally rectangular pattern of spray holes.

A comb includes a hollow frame having a pair of fixed teeth at opposite ends thereof, and a cap having a depending body portion disposed within the hollow interior of the frame. A series of transversely extending open slots in one longitudinally extending side planar face of the body portion receives individually a series of axially rotatable rod-like teeth. Each one of the open slots is four-sided in cross-sectional shape, and the fourth side is open in the plane of the face. The depth of the slots is greater than the thickness of the teeth so that the teeth fit entirely within the slots. In one embodiment of the present invention, the teeth are made by rotating axially rod stock and moving a cutter having the configuration of the desired shape of the teeth into cutting engagement with the rod stock. In another embodiment of the present invention, the teeth are formed from rod stock placed in a cavity having the shape of the body portion of the teeth to be formed, and then moving a die axially into engagement with one end of the rod stock to cause the rod stock to flow into the shape of the desired tooth.

Toilet flushing apparatus for use in a toilet assembly having a drain valve seat, includes a flush valve assembly for enabling a partial flushing operation to occur for conserving the use of water. The flushing valve assembly includes a floating flapper valve device for sealing the drain valve seat, the floating flapper valve device including an air trapping float chamber and an inlet mounted in fluid communication with the chamber for trapping air in the chamber to delay the closing of the flapper device. A vent mounted in fluid communication with the chamber enables at least some of the trapped air to be released from the chamber for enabling the flapper device to close prematurely, thereby causing a partial flush operation to occur. In one form of the invention, a trip lever assembly directly controls the operation of the floating flapper valve device for full flush operations, and it is adapted to control the vent for a partial flushing operation.
