Abstract
A showerhead includes a housing which defines different sets of spray outlets and includes a mounting for the housing that defines a path of water flow from an inlet. Formed on the housing are circumferentially-spaced grooves and formed on the mounting are mating lugs. Lands disposed between successive ones of the grooves include a cam surface which elevates in continuation toward the entrance of a next groove and then terminates in a step leading toward the bottom of that next groove, as a result of which the assembly atop the lands and subsequent movement of the lugs over the cam surface lockingly drops the lugs into corresponding ones of the grooves. The mounting includes a handle through which water flows and which is removably received within arms of a bracket to which water is supplied and therefrom led into the handle. A channel within the body of the bracket accepts a shank projecting from a pivot ball which sealing seats within a nut that, in turn, is threaded onto a water-supply pipe. The inner end of the shank is locked into place by means of inner interengaging lugs and ears which cooperate with a retainer that inhibits their inadvertent or intentional disassembly.
