ABSTRACT:
A cutting blade drive assembly for a hair clipper comprises a frame and a driven assembly rotatable on the frame about an axis fixed relative to the frame. The driven assembly includes a tension spring, and a cutting blade is engaged by the tension spring for reciprocal movement in response to oscillation of the drive assembly. The driven assembly also includes a mechanism for adjusting the tension in the tension spring. A drive unit on the frame operatively connects the driven assembly with an electric motor, which can also be supported on the frame, for oscillating the driven assembly about the axis to impart reciprocative movement to the cutting blade engaged by the driven assembly. The cutting blade drive assembly can be removably supported as an integral unit in the housing of a hair clipper so that the entire drive assembly may be readily removed from the housing for repair or replacement.
