ABSTRACT:
A novel comb attachment for use with a hair clipper is disclosed herein. The comb attachment is adapted to fit over the front portion of the hair clipper including a cutter assembly having an elongated cutting edge. The cutter assembly comprises a movable cutter reciprocating with respect to a stationary cutter, these cutters defining therebetween a cutting plane. Formed in the front end of the attachment is a series of spaced comb teeth the row of which is in close and parallel relationship with the cutting edge of the cutter assembly for guiding hairs into the cutting edge. Each of the comb teeth is formed at the location above the cutting plane with at least one barb projecting on its side and upper faces to define therebehind a rearwardly oriented shoulder. These shoulders act as stoppers for the clipped hair strands which have been sheared and fed rearwardly of the cutting edge when advancing the hair clipper through a user's hair for a continuous hair cut. Accordingly, the clipped hair strands can be well prevented from gliding back to the tips of the comb teeth and into the cutting edge during the advancing movement of the hair clipper, whereby assuring a smooth cutting action which is free from the reentry of the clipped hair strands in the cutting edge, while retaining a smooth combing action by the comb teeth.
