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.
Claims8
In a car washer assembly:
- a cylindrical scrubbing brush having a longitudinal axis of symmetry for contacting a vehicle in a wash lane;
- means for rotating the brush about said axis;
- support means carrying the brush in a position to contact vehicles in the wash lane with said axis transversely to the lane;
- and power means operatively connected with said support means for axially reciprocally displacing the brush relative to the wash lane while contacting a vehicle, said support means comprising a first frame suspended over the wash lane and supporting the brush with the axis thereof substantially horizontal for relative displacement over vehicles in the lane;
- said frame further including first and second pivotal and rigid parallel arms of equal length, the brush being carried by and between the arms, the power means being connected to at least one of the arms to control the angular relation between the arms and the brush thereby to laterally shift the brush relative to the wash lane.
