Abstract
Abstract A pair of motored side brush carriages are mounted on a motored trolley, supported on a pair of inclined side rails, and capable of travelling forwardly by a force exerted by an advancing vehicle and backwardly under the drive of a motor. Said side brush carriages are mounted on respective aligned guide tracks, formed on said trolley for movement toward and away from each other. With this arrangement, the side brushes are automatically operated to follow the contour of the vehicle, at all times under the same pressure of contacting engagement with the vehicle irrespective of its speed, relative to the vehicle cleaning apparatus.
