Abstract
An electric hair cutting apparatus having a motor for rotating a shaft, which rotates an eccentric about the axis of the shaft, but not about the central axis of the eccentric. A cylindrical bearing is positioned around the eccentric. A drive tip is provided with a follower end which is shaped and positioned to engage with the bearing surrounding the eccentric. As the eccentric rotates, the bearing alternately pushes on left and right arms of the follower end of the drive tip, causing the drive tip to oscillate back and forth about a pivot point. The angle of the bearing with respect to the eccentric allows for generally continuous contact between the arms of the follower end of the drive tip with the bearing, even throughout the pivoting of the drive tip.
