A new and improved vehicle wash apparatus having a rigid arm with opposite ends. One end is journaled about a generally vertically extending pivot to a washer frame which extends over the vehicle being washed. The rigid arm at its distal end is journaled about a horizontally disposed pivot rod connected to a moveable arm extension having a distal end. A rotary brush is journaled at the distal end of the moveable arm extension for rotation about a vertical axis. The moveable arm extension and brush is moveable both inwardly and outwardly of the vehicle wash frame on both sides of the vertical position and being biased inwardly thereof. The rigid arm is biased into a position generally transverse to the movement of the vehicle being washed relative to the arm, whereby the rotating brush is always in contact with the vehicle being washed. The invention also includes an improved vehicle wash apparatus having such a vehicle wash arm and brush whereby both sides and both ends of the vehicle are all washed in one pass through the vehicle wash apparatus.
A vehicle washing machine comprising a frame having opposite ends and opposite sides, an endless track secured to said frame between said opposite ends and opposite sides, an arm mount within said track, said arm mount being moveable within said track, a motor operatively connected to said arm mount for moving said arm mount within said track, a wash arm having opposite ends, said wash arm being pivotally connected to said arm mount at one of said ends by a generally vertical pivot pin, said wash arm being moveable through a first arc about said generally vertical pivot pin, said frame defining vehicle wash locations between said opposite ends and sides of,said frame, said track being within the periphery of a vehicle positioned in said vehicle wash locations, said wash arm having an extension, said arm extension being pivotally connected to the other of said ends of said wash arm by a generally horizontal pivot pin, said arm extension being moveable through a second arc about said horizontal pivot pin, said arm extension having a distal end, a rotating brush mounted on a shaft journaled in said distal end of said arm extension and rotatable about an axis generally perpendicular to said horizontal pivot pin, whereby said rotating brush may move through said first arc to engage the ends and sides of said vehicle and move through said second arc to accommodate irregularities from the generally vertical planar surfaces of said vehicle ends and sides as said arm mount is moved within said track.
