ABSTRACT:
A car wash apparatus comprising a support frame, a first brush support frame depending from the frame, a second brush support frame depending from the first frame and a horizontal brush carried by the second frame for rotation about a substantially horizontal axis. The double frame permits the brush to contact the top and front and rear end surfaces of a vehicle. Power means in the form of a fluid cylinder are provided for swinging the opposite parallelogram arms of the first frame during engagement of the rotating brush with a vehicle thereby to impart a reciprocating axial displacement to the scrub brush as it contacts a vehicle.
