ABSTRACT:
A precision hair clipper for cutting the hair of a subject to a uniform length comprises a housing defining a flow chamber attachable to a vacuum source. At the inlet of the housing a pair of reciprocating blades occupy one side of a quadrangular rim. The blades have rows of cooperating teeth facing the opening of the inlet. A bar commensurate with and parallel to the blade teeth is reciprocally translated across the opening between the teeth and the opposite edge of the rim. Hair drawn through the flow chamber is thus periodically pushed against the shearing teeth. The bar movement is coupled to the blade oscillating mechanism.
