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.
