ABSTRACT:
As a car moves along a path through a wash area, it engages a pair of rotating cloth scrubbing wheels. Each wheel depends from a carriage movable along a horizontal boom pivotally mounted at one end upon a standard located at each side of the wash area. Each boom is pivoted upon a vertical axis and is swingable in a horizontal plane between a first position angular to the path and a second position parallel to the path. Each carriage is biased towards the free end of the boom whereby engagement of the car causes the boom to rotate outwardly while the wheel moves over and engages the front of the car, until the wheel engages the front corner of the car thereby operating a limit switch as a result of car movement which shifts a three-way valve to release the pressure on the carriage cylinder. The carriage moves up the boom towards the pivoted end thereof as the boom swings into a path generally parallel to the car whereby the wheel operatively engages the side of the car to the rear corner thereof. Upon actuation of the limit switch and valve, the carriage is moved by its energized cylinder towards the free end of the boom as the wheel cleans the rear of the car to the center thereof and as the boom is swung towards the center to the first position.
