ABSTRACT:
A vehicle washing apparatus, particularly effective for scrubbing the upper portions of a vehicle as it moves along a predetermined path through a wash bay or the like, including an overhead carriage extending transversely of the vehicle path and a plurality of curtain or sheets of flexible, felt-like material extending in facing relation below the upper portions of the vehicle. The lower portions of the sheet include a plurality of vertical slits forming a plurality of narrow ribbons or strips. The carriage is reciprocated or oscillated through an arcuate path about a horizontal axis extending transversely of the vehicle. This oscillatory movement of the carriage imparts both a fore and aft and up and down movement on the strips with respect to the vehicle, providing a circulatory-like scrubbing action on the upper portions of the vehicle.
