ABSTRACT:
A hair cutter has a vacuum source connected tubular barrel and an interior shaft mounted turbine assembly. The turbine assembly includes a turbine coupled to a flywheel which in turn is coupled to a rotary blade assembly. A stationary radially disposed blade arrangement engages the rotatory blade arrangement. A pivot shaft arrangement is supported on the inside of the barrel joined to a longitudinal movable sleeve for adjusting the positioning of the internal assembly and couples the turbine to the flywheel and the flywheel to the rotary blade assembly. The turbine is coupled to the rotary blade assembly to create a rotary force to both rotate the rotary blade against the fixed blade, and to enhance the scissors force of the rotatory blade against the first blade by longitudinally urging the rotary blade toward the turbine. A vacuum source coupled to the barrel drives the turbine at one end of the barrel and the blade assembly is disposed adjacent an opening at the opposite end of the barrel. A grating is adjacent to and spaced apart from the blades.
