ABSTRACT:
A precision hair clipper for cutting the hair of a subject to a uniform length which comprises a housing defining a flow chamber attachable to a vacuum hose. At the inlet of the housing a pair of reciprocating blades are configured to maintain a constant and equal flow of air through the chamber. Each of the blades is symmetrical to the other and features a row of parallel, sharp-edged slots. The row of slots of each blade is slanted in opposite direction to the row of the other blade so that their lateral oscillation results in a plurality of criss-crossing shearing edge action. The blades are driven by a pair of oppositely phased eccentric cams engaging openings in the blades. Selectable spacing of the clipper in relation to the subject's scalp is provided by a series of snap-on adjustable spacers.
