ABSTRACT:
A car wash mechanism includes a vertical rotating brush mounted on the end of a horizontal boom slidably received in a cage mounted on an upright standard to the side of the path of travel of a vehicle. The bottom of the cage is mounted to the standard for pivotal movement and the top of the cage is pivotally mounted on a slidable carriage. The cage can be tilted between one position in which the boom will extend outwardly of the cage towards the center of the track and a second position in which the boom will retract inwardly of the cage and thereby position the brush closer to the standard. A fluid cylinder is actuated to shift the carriage and thereby tilt the cage under the control of a switch which has its actuator engaged by the cage when the cage is pivoted to the side by a passing vehicle.
