Showerhead control

A showerhead control structure including means to control both waterflow and temperature therethrough for connection to a hot and a cold water line comprising:

• (A) a showerarm adapted to be rigidly connected to a wall, said showerarm having separate hot and cold water ports extending longitudinally therethrough having respective hot and cold water water supply connection means, said hot and cold water ports discharging into a first ball and socket water flow control valve structure including a ball having separate hot and cold water through openings, a diametrical through bore in said ball extending transverse to said through openings having a connector recess at an upper end of said through bore, seal means in a lower portion of said through bore and said ball including a spherical valve surface portion providing substantially universal movement in the socket of said first ball and socket water flow control valve structure with respect to the hot and cold water discharge ports, said first ball and socket water flow control valve structure permitting water flow from said showerarm to said respective hot and cold water through openings in at least one universal position and the flow of water into said ball being blocked by said spherical valve surface in at least one other universal position, said first ball and socket water flow control valve structure including peripheral connector means for retaining said ball and socket in engagement, said first ball and socket water flow control valve structure having a combined hot and cold water flow passageway downstream of said diametrical through bore, said first ball and socket water flow control valve structure being provided with means for connection to a showerhead downstream of said ball,
• (B) a second rotatable water flow control valve structure defined by an elongate control operator having a distal end and an upper end, said elongate control operator being journalled in said diametrical through bore, said upper end having spaced respective hot and cold water chordal cut-out means positioned to cooperate with respective downstream ends of said hot and cold water through openings to vary the water-flow temperature downstream of said elongate control operator upon rotational adjustment of said elongate control operator with respect to said ball when said first ball and socket water flow control valve structure is in a position permitting water flow from said showerarm to said ball.
