Variable diameter cleaning brush
First Claim
1. A tubular type brush for use in a cleaning machine including a generally cylindrical driver tube adapted to be rotated about its axis for use in cleaning an adjacent surface, said driver tube having an exterior surface with circumferentially and axially located bristles extending outwardly therefrom, said bristles extending, when the driver tube is in an at rest position, in a direction which is closer to parallel with the driver tube exterior surface than perpendicular to the driver tube exterior surface, said bristles having tips which move outwardly from the driver tube exterior surface as said driver tube rotates, with the degree of said outward movement being dependent, at least in part, upon rotary speed of the driver tube, the exterior surface of said driver tube including a plurality of generally parallel closely spaced adjacent grooves, each of said grooves being parallel with the axis of said driver tube, a plurality of generally parallel bristle carriers, with each carrier being mounted in one of said adjacent grooves, the bristles on the exterior of said brush being arranged in groups, with each group being mounted in a respective one of said bristle carriers.

Abstract
A tubular type brush for use in a cleaning machine includes a generally cylindrical driver tube adapted to be rotated about its axis for use in cleaning an adjacent floor surface. The driver tube has an exterior surface with circumferentially and axially located bristles extending outwardly therefrom. The bristles extend, when the driver tube is in an at rest position, in a direction which is closer to parallel with the driver tube exterior surface than perpendicular to the driver tube exterior surface. The bristles have tips which move outwardly from the driver tube exterior surface as the tube rotates, with the degree of the outward movement being dependent, at least in part, upon rotary speed of the driver tube.
