Car washing mechanism

A car wash mechanism adapted to be positioned to one side of a path for vehicles, comprising:

• a vertical standard;
• a generally horizontal boom mounting a vertical rotating brush at one end;
• a cage slidably receiving said boom;
• means mounting said cage on said standard for pivotal movement of said boom relative to said standard and for tilting movement of said cage between a first position in which the boom slides outwardly of the cage and toward the center of the path and a second position in which the boom retracts within the cage;
• and
• means for tilting said cage between said positions, said means being responsive to the pivotal position of said boom relative to said standard.

A car wash mechanism adapted to be positioned to one side of a track for vehicles, comprising:

• a vertical standard having a cross-arm;
• a generally horizontal boom mounting a vertical rotating brush at one end;
• a cage slidably receiving said boom;
• means pivotally mounting the bottom of said cage on said standard;
• a carriage slidably received on said cross-arm, said carriage pivotally mounting the top of said cage;
• means for shifting said carriage to tilt said cage between a first position in which the weight of the brush at the end of the boom causes the boom to slide outwardly of the cage and toward the center of the track and a second position in which the weight of the brush will cause the boom to retract within the cage;
• and
• means responsive to the pivotal movement of the cage to cause said shifting means to move said cage to said second position whenever the boom is forced to the side by a passing vehicle.
