  • Patent number: 5040339
    Abstract: An apparatus for polishing surfaces includes an elongated handle having a mounting head on one end thereof that carries a pair of counter rotating polishing drums. The mounting head is rotatably mounted on the end of the handle to permit rotation of the polishing drums in unison for easily following a contoured surface. The handle of the apparatus is hollow with an exhaust vent at a remote location from the rotating heads so that high-pressure air that is delivered through a conduit in the hollow handle to the pneumatic motors driving the polishing drums can be exhausted through the hollow handle which muffles the sound and also allows lubricant fluids conventionally entrained in the high-pressure air to be removed at a remote location from the polishing drums.
