Claim:
A rollover car washer characterized by the absence of floor track mounted, vertically enclosing gantry structures located laterally of vehicles being washed while stationary in a wash location comprising: a longitudinal support track mounted sufficiently overhead of a car wash location to permit a vehicle to pass thereunder; a carriage mounted on said support track for reciprocal longitudinal movement therealong and over said location; said carriage having closed cabinetry enclosing and supporting chemical containers, valves and a motor for driving the carriage along said track; a first side-by-side pair of side brushes of a vertical length approximating the vertical height of a passenger vehicle and having vertically depending axle shafts connected to horizontal support arms pivotally mounted to the carriage so as to extend outwardly from said carriage in use for relatively converging and diverging movement across said location sufficient to allow a vehicle to pass therebetween while said pair or brushes washes the outer surfaces thereof; a second side-by-side pair of side brushes having a vertical length approximately equal to the vertical height of a passenger vehicle and having vertically depending axle shafts mounted to support arms which are pivotally connected to the carriage so as to extend rearwardly and outwardly from said carriage in use for relatively converging and diverging movement across said location and across the vehicle in said location and sufficiently to allow a vehicle to pass therebetween said first and second sets of side brushes being arranged in pairs which are longitudinally spaced from one another relative to the wash location; each of said side brushes having a top-mounted drive motor connected to a respective axle shaft the entirety of said carriage, cabinetry, support arms and top mounted drive motors for said side brushes being placed at elevations greater than the passenger sight lines from within a passenger vehicle in said location in all positions of said carriage and brushes, and said washer being entirely free of cabinetry and enclosing structure within said sight lines such that lateral visual obstructions to persons in vehicles being washed are minimized.
