Abstract
A Cardan gear assembly wherein rotary input motion of the main shaft is converted to elliptical output at the Cardan gear output centerpoint. The Cardan gear output centerpoint is connected via a ball and a pin slideable therethrough to a support having a work performing instrumentality arranged at its distal end. During operation, the elliptical output motion of the Cardan gear output centerpoint is transmuted into three dimensional, elliptical like motion at the tip of the work performing instrumentality.
