ABSTRACT:
There is disclosed a vehicle wash apparatus including a wash arch frame carried on tracks extending longitudinally of a wash stall in which a car to be washed is parked. Overhead arms are pivotally carried on their respective one ends from an overhead transverse horizontal pivot shaft and mount a horizontally disposed rotary top brush from the free ends thereof for selective lowering into a position for contacting the front of a vehicle to wash the grill and for travel rearwardly along the hood, top and trunk of the vehicle. Side brush arms are carried pivotally from the sides of the arch frame for rotation about vertical axes and project in a direction opposite the direction in which the top brush arms, in their retracted positions, project and are urged inwardly to wash the sides of the car as the arch carries the top brush rearwardly on the tracks. Such side arms are pivoted inwardly as the side brushes clear the rear corners of the car to carry the side brushes about the rear corners of the vehicle to wash the rear thereof as the top brush completes washing of the top of the trunk.
