Abstract
A power brush e.g. for a vacuum cleaner or street sweeper has its bristle bodies swivelably mounted on a member which is given an orbital movement so that the eccentric axes of the bristle bodies with respect to their swivel axis induces an additional oscillatory motion of each bristle body as it moves in the orbital path generated by the motion of the member on which its carrier is mounted.
Claims15
A power-driven brush, comprising:
- a support displaceable in a travel direction over a surface adapted to be treated by the brush;
- at least one member mounted on said support for displacement in a cyclical pattern with at least a component of said displacement being transverse to said travel direction;
- a plurality of bristle carriers swivelably mounted on said member for pivotal movement about respective axes transverse to said surface;
- respective bodies of bristles affixed to said carriers and each having an axis offset from the respective axis of pivotal movement of the respective carrier whereby the displacement of said member in said cyclical pattern causes said bodies to sweep said surface and induces each carrier to swivel relative to said member;
- and
- drive means on said support operatively connected to said member for cyclically displacing the same relative to said support.
