ABSTRACT:
The spray pattern of a shower head may be varied by threading the faceplate of the head axially relative to its housing to change the effective cross-sectional areas of tapered grooves in pattern control elements which project through openings in the faceplate and which rotate as a unit with the faceplate during its manipulation. One embodiment has a mounting ring for the control elements which is rotatably retained on the central arbor of the head by a collar bonded to the tip end of the arbor. A second embodiment has a mounting ring for the elements which is threaded onto the exterior of the arbor in a manner to provide relative linear displacement between the faceplate and the elements when the faceplate is threaded into or out of the arbor, and a third embodiment utilizes a threaded collar at the tip end of the arbor to retain the freely rotatable mounting ring for the elements in place on the arbor. The faceplate of each of the three embodiments it telescopically received within the housing at its outlet, while a fourth embodiment has a faceplate that is disposed outside of the housing and telescopically receives the outlet thereof.
