Portable scrubbing tool

A lightweight, portable, highly maneuverable, pneumatic powered scrubbing tool for scrubbing remote and irregularly shaped aircraft surfaces comprising a scrubbing brush member having a substantially circular mounting plate, and a plurality of bristles affixed to one surface of the plate, at least a portion of said bristles affixed to said plate adjacent the periphery thereof and directed at an angle outwardly therefrom, a compressed air-powered motor having a motor drive shaft connected to said plate for rotating said plate, said motor positioned adjacent the other surface of said plate, and of a size so as not to extend beyond the periphery of said plate so that said motor will not interfere with the surface to be scrubbed, said motor drive shaft extending from one end of the motor along its major axis, and fixedly connected to said plate for rotating said plate, said major axis of said motor extending substantially perpendicular to said plate, an elongated, tubular, main support pole, means for pivotally connecting one end of said main support pole to said motor so that said main support pole and motor are freely pivotable with respect to each other in use, a flexible pneumatic compressed-air supply hose within said main support pole extending from the other end of said main support pole and through an opening defined in a peripheral portion of the main support pole and connected to said motor, said opening located adjacent said one end of the main support pole, a pneumatic fitting connected to said supply hose, said fitting mounted at the other end of said main support pole, and a secondary main support extension pole for interconnection with said main support pole, comprising an elongated hollow pole, a second flexible pneumatic compressed-air supply hose within said hollow pole and interconnected with said pneumatic fitting for fluid communication with said first supply hose, said secondary extension pole coaxial with said main support pole.
