Multi mode shower head
First Claim
1. A multi-mode shower head or handset in which a body member or cartridge is secured for relative angular movement to the head and has a valve-like cooperation with the hollow interior of the head for directing water flow from the head via passageways in the cartridge to arrangements of showering mode outlet openings including fine spray outlet openings at the front face of the cartridge, the showering modes from said outlets being selected by turning the cartridge to appropriate settings on the head, and a series of cleaning pins rotatable with the cartridge and coaxially movable relative thereto for cleaning penetration into corresponding fine spray outlet openings and withdrawal therefrom;
- characterized in that the series of cleaning pins are operated for such co-axial cleaning movement by an arrangement of follower means and a co-operating cam profile or track acting between a carrier member or ring carrying the series of cleaning pins and the head whereby the cleaning pine remain in an inoperative withdrawn position during and between any of the showering mode settings of the cartridge and are only independently operated for cleaning movement by co-action between the follower means and operative cam formation of the cam profile or track on further turning movement of the cartridge beyond its showering mode settings.

Abstract
A cartridge (2) secured for angular movement on the handset head (10) has a valve-like cooperation with openings (12) in the head (10) for water flow via passageways (20, 21, 22) in the cartridge (2) to showering outlets (30, 31, 32) on appropriate rotational setting of the cartridge (2). Cleaning pins (7) rotatable with the cartridge (2) and co-axially movable relative to it are operated by a cam track (8, 81) to penetrate fine spray outlets (32) to clean them of scale. The cam co-action of the pin ring followers (71) with the track (8) causes the pins (7) to remain inoperative during the showering modes but the pins (7) are operated for penetration by further turning of the cartridge (2) i.e. independently of the showering modes. The followers (71) are spring urged against the track (8) such as by resilient blades (75) bearing against the taper periphery (27) of the cartridge (2). Clearance pin penetration of the outlets (32) permits water flow to wash away scale and minimize back pressure. Angular movement of the cartridge (2) is limited by stops (83, 84) and showering settings are located by cam track recesses (82).
