Contaminant resistant straight line motion shower pipe assembly

A contaminant resistant straight line motion shower pipe assembly apparatus comprising:

• a base;
• a first arm rotatable about a first axis, said first axis being stationary relative to said base during rotation of said first arm;
• a second arm rotatable about a second axis extending through said first arm wherein the distance between the first axis and second axis remains constant;
• said second arm being of a length relative to the distance between the first and second axis to produce a straight line motion at a pivotal connector affixed to said second arm upon rotation of said second arm about said second axis a constant distance per degree of rotation of said first arm about said first axis;
• means for rotating the second arm about said second axis a constant distance per degree of rotation of said first arm about said first axis to produce a straight line motion at said particular location on said second arm;
• a shower pipe pivotally supported by said second arm by means of said pivotal connector such that said straight line motion is produced along an axis of said shower pipe;
• and
• the distance between said pivotal connector and said second axis being less than the distance between said first axis and said second axis.

A straight line motion producing apparatus comprising:

• a base;
• a first arm rotatable about a first axis, said first axis being stationary relative to said base during rotation of said first arm;
• a second arm rotatable about a second axis extending through said first arm wherein the distance between the first axis and second axis remains constant;
• said second arm being of a length relative to the distance between the first and second axis to produce a straight line motion at a particular location of said second arm upon rotation of said second arm about said second axis a constant distance per degree of rotation of said first arm about said first axis;
• and
• means for rotating the second arm about said second axis a constant distance per degree of rotation of said first arm about said first axis to produce a straight line motion at said particular location on said second arm;
• the distance between said particular location and said second axis being less than the distance between said first axis and said second axis.

A shower pipe assembly comprising:

• a shower pipe;
• means for oscillating the shower pipe along an axial path;
• a base;
• oscillating support means coupled between the base and the shower pipe and supporting the shower pipe from a point on the support means which is constrained by operation of the support means to oscillation along a straight line path;
• said oscillating support means comprising:
• a first arm rotatable about a first axis, said first axis being stationary relative to said base during rotation of said first arm;
• a second arm rotatable about a second axis extending through said first arm wherein the distance between the first axis and second axis remains constant;
• said second arm being of a length relative to the distance between the first and second axis to produce a straight line motion at a pivotal connector affixed to said second arm upon rotation of said second arm about said second axis a constant distance per degree of rotation of said first arm about said first axis;
• and
• means for rotating the second arm about said second axis a constant distance per degree of rotation of said first arm about said first axis to produce a straight line motion at said particular location on said second arm, wherein said means for rotating comprises a first pulley having its central axis being coaxial with said first axis and being incapable of rotating relative to said first axis, a second pulley having its central axis being coaxial with said second axis, and a belt engaged to the first pulley and the second pulley to prevent slippage between the belt and the first pulley, and to prevent slippage between the belt and the second pulley,
• said shower pipe being coupled to said second arm at said particular location of straight line motion of said second arm.
