US Patent:

42020689, May 13, 1980

Filed:

Nov 14, 1978

Appl. No.:

5/960633

Inventors:

Frank R. Lester - Boynton Beach FL
James Bullard - Adair OK

Assignee:

Nuvite Chemical Compounds Corporation - Brooklyn NY

International Classification:

A46B 1302

US Classification:

15 28

Abstract:

A lightweight pneumatic powered portable scrubbing tool is disclosed, having a scrubbing brush member that is rotated by a cylindrically-shaped elongated air powered motor. The motor shaft is affixed to the brush member and supports the brush member. The motor housing is pivotally connected to an elongated main support pole, having an air supply hose disposed therewithin and along the length thereof. The air supply hose exits, through a union, from a peripheral portion of the main support pole and is interconnected with the motor. A fitting is mounted on an opposite end of the main support pole, i. e. , remote from the motor, for interconnection with a fluid source through an air hose. An extension support pole fits over the main support pole and can be extended to a preselected position along the length of the main support pole. Rotation of the extension support pole in either direction relative to the main support pole permits locking of the extension pole to the main pole.

Abstract:

A lightweight pneumatic powered portable scrubbing tool is disclosed having a scrubbing brush member that is rotated by a cylindrically-shaped elongated air powered motor. The brush member has a substantially circular mounting plate and a plurality of bristles affixed to a surface of the plate. At least a portion of the bristles are adjacent the periphery of the plate and are directed at an angle outwardly therefrom. The motor shaft is affixed to the brush member and supports the brush member. The motor housing is pivotably connected to an elongated main support pole, having an air supply hose disposed therewithin and along the length thereof. The air supply hose exits from a peripheral portion of the main support pole and is interconnected with the motor. A quick-disconnect fitting is mounted on an opposite end of the main support pole, i. e. , remote from the motor, for interconnection with a fluid source, or a secondary main support pole.
