Abstract
A window scraper brush is disclosed. The brush has a brush support defining a longitudinal axis and a plurality of filaments extending from a portion of the brush support. The filaments are tapered with the tips of the filaments defining a longitudinal filament edge substantially parallel to the longitudinal axis. Preferably, the brush has brass filaments and an axle about which the brush can be oscillated. The brush preferably includes camming structure cooperable with a housing to cause the brush to move toward and away from a work surface during a portion of each oscillation of the brush about the axle.
Claims23
A brush for removing substances from a surface comprising:
- an elongated brush support defining a longitudinal axis, the support having an axle substantially aligned with said axis, and a plurality of filaments secured proximally to a portion of the support and extending distally from the brush support, said axle for rotatably mounting said support, the plurality of filaments being tapered to define at the distal end thereof a longitudinal filament edge parallel to the longitudinal axis;
- and
- camming means attached to the support for engaging a cam surface to transversely reciprocate the brush longitudinal axis toward and away from a work surface adjacent the longitudinal filament edge as the brush rotates on said axle.
The brush of claim 22 wherein the camming means is attached to the axle.
A brush for removing substances from a surface comprising:
- an elongated brush support defining a longitudinal axis, said brush support adapted to be mounted for rotation about said axis;
- a plurality of filaments extending from a portion of the support, the plurality of filaments being tapered to define a longitudinal filament edge parallel to the longitudinal axis;
- and
- camming means attached to the support for engaging a cam surface to transversely reciprocate the longitudinal axis toward and away from a work surface adjacent the longitudinal filament edge as the brush rotates about said axis of rotation.
A brush for removing substances from a surface comprising:
- an elongated brush support defining a longitudinal axis of rotation;
- the support having an axle aligned with the longitudinal axis of the support, said axle for rotatably mounting said support;
- a plurality of filaments extending from a portion of the support, the plurality of filaments being tapered to define a longitudinal filament edge parallel to the longitudinal axis;
- and
- camming means attached to the support for engaging a cam surface to transversely reciprocate the axle toward and away from a work surface during rotation of the brush about the axle.
A brush for removing substances from a surface comprising:
- an elongated brush support defining a longitudinal axis;
- a pair of axle pins protruding from opposite longitudinal ends of the brush support to define a brush axle aligned with the longitudinal axis;
- a plurality of filaments extending from a portion of the support, the plurality of filaments being tapered to define a longitudinal filament edge parallel to the longitudinal axis;
- and
- camming means attached to the support for engaging a cam surface to transversely reciprocate the longitudinal axis toward and away from a work surface adjacent the longitudinal filament edge as the brush rotates on side axle.
A brush for removing substances from a surface comprising:
- an elongated brush support defining a longitudinal axis and having an axle aligned with the longitudinal axis;
- a plurality of brass filaments extending from a portion of the support, the plurality of filaments extending beyond the ends of the support in the direction of the longitudinal axis, the filaments further being tapered to define a longitudinal filament edge parallel to the longitudinal axis;
- and
- camming means attached to and extending longitudinally from the brush support to transversely reciprocate the longitudinal axis toward and away from a work surface adjacent the filament edge as the brush rotates on said axle.
