  • Patent number: 4524480
    Abstract: A wire wheel cover brush, for cleaning automobile wire and style type wheel covers having a brush handle portion, tapering head portion and bristle portion. The brush bristle portion has a plurality of individual U-shaped or hairpin bent brush bristles gathered together in a plurality of tufts. The tufts are embedded in holes drilled or otherwise formed in the brush head portion and secured by fastening means. The tufts are arranged in three distinct groupings each in a circular pattern. The groupings are positioned in a triangular arrangement separated by a predetermined space to allow passage of the wire wheel cover spokes between the groupings, allowing the groupings to make maximum and direct contact with the back-up plate, simultaneously cleaning the back-up plate and wire spokes. An alternative embodiment is disclosed in which the brush bristles are of two different lengths.

  • Patent number: 4514872
    Abstract: An improved escalator tread cleaning brush (12) is disclosed for use in cleaning the steps (14) of an escalator (10). A brush bar (28) forming a portion of the brush (12) mounts first, second and third sets of bristles (44, 46, 52). The first set of bristles is formed of wire tufts and has a relatively elongate length for brushing the grooves (18) in the steps (14). The second set of bristles is formed of wire tufts and has a relatively short length for cleaning the tread (16) of the steps (14). The third set of bristles is formed of plastic tufts and has a relatively elongate length for cleaning the grooves (18). A spring bar (42) can be used to urge the bristles into cleaning contact with the steps (14).

  • Patent number: 4454622
    Abstract: This invention concerns a nail polish brush so constructed as to provide more even and exact stroking, especially onto the top of the fingernail, where the cuticle is rounded. The hairs on the perimeter of the brush are shortest in length, the next circle of hairs lying inside the outer circle of hairs are slightly longer, each successive circle of hairs increasing in length this way, and the last round of hairs in the center of the brush are the longest. The entire effect is one of very slight, gradual rounding, corresponding more exactly to the human cuticle.

  • Patent number: 4307479
    Abstract: A rotary brush assembly, suitable for use in a vacuum cleaner, is disclosed. The assembly includes a generally cylindrical brush roller body carrying an array of helical rows of bristle tufts. In one embodiment, bristle tufts near a midplane normal to the roller body axis and equidistant between its ends are substantially normal to the roller body axis. Other bristle tufts are angled away from the midplane in an amount which is an increasing function of their distance from the midplane. Bristle stiffness is an increasing function of the degree of tuft angulation.In another embodiment, the roller body defines helical grooves in its outer surface, and two brush strip substrate portions bearing the bristle tufts are inserted end to end in each groove. Adjacent brush strip ends define structure for interlocking the brush strips for inhibiting longitudinal separation of the brush strips, which would otherwise tend to result from brush rotation.
