Abstract: A dry wiping system for use in a mechanized car wash establishment in which an automobile moves along a defined path comprises a series of strips of water absorbent material suspended from a carrier above the path of the automobile. The carrier, which moves the strips so that they wipe across the wet exterior surfaces of the automobile, is guided along a circuit which causes the strips to be carried across the path of the automobile at an angle such that the strips have a substantial component of motion in a direction opposite the motion of the automobile substantially throughout each traverse of the path. Preferably, the circuit of motion is of triangular form and the system also includes a pair of power driven wringer rollers positioned to receive the strips after they have passed across the automobile to dewater the strips prior to their next excursion across the automobile.

Abstract: A vehicle conveyor suitable for a car wash is described wherein tire-engaging rollers are attached to a continuous chain positioned underneath the path of the vehicle. The rollers are normally carried by the chain in a nonengaging position below the vehicle track. Then, when movement of the vehicle is desired, a coin-actuated control or a manual control is actuated to move a cam into operative position to cam one of the rollers upwardly through a slot onto the top surface of the vehicle track where it engages the vehicle's tire. The roller subsequently drops through a slot proximate the end of the conveyor course.
