ABSTRACT:
This vehicle washing apparatus includes a pair of side brush assemblies mounted to a gantry, each brush assembly including a shaft carrying upper and lower rotary brush units. The lower brush unit of each assembly is fixedly mounted to its shaft for rotation with the shaft while the upper brush unit is mounted for rotation relative to said shaft by virtue of an adjustable clutch connection between the upper brush unit and the shaft so that said upper unit is subject to slippage when the brush engages a projection on the side of the vehicle. The shaft includes a jointed lower portion carrying an actuating finger which operates a switch to reverse direction of shaft rotation when the lower portion is tilted out of vertical alignment.
