  • Hairbrush having means to collect trapped strands of hair for removal from the bristles
    Patent number: 5519912
    Abstract: Hairbrushes are disclosed having an array of bristles for grooming either humans or animals. Loose strands of hair that become trapped among the bristles during the brushing strokes are collected and relocated for quick and easy removal from the brush. The foregoing is achieved by either sliding a hair collecting plate axially along the bristles or by moving a bristle carrying plate to which the bristles are connected through a hollow brush head so that the bristles slide axially through holes formed in the top of the brush head.
