Abstract

A hair cutting and trimming device having an electrically operated clipper enclosed in an elongated housing, distance between the cutting teeth of the clipper and the hair intake end of the device being selectively variable to permit cutting hair to varying lengths to suit modern styles of haircuts, air suction means being incorporated at the closed end of the housing to draw hair through the open end of the housing toward the cutting end of the clipper and to remove the clippings. Hair guide deflector means are incorporated to ensure that all hair that reaches the cutting end, will pass between the teeth of the cutter and be cut. Control means controlling movement of the clipper relative to the open end of the housing ar incorporated, providing countable increments of motion to permit accurate styling of haircut during the haircutting operation. Programming means are incorporated to permit styling to preselected patterns on hair styling maps containing length indications on various portions of the maps to correspond with length markings on the selectively variable distance means on the device.
