Description: |
Abstract:
Variable-speed and reversing gearing employed in a boring and turning mill is controlled by the movements of a single handle through a sliding and rocking shaft. The handle D, Fig. 3, is pivoted to the shaft A at E and has a ball end D<2> serving as a fulcrum and working between curved guides C. In a modification, the handle rocks the shaft through a splined sleeve H to which it is pivoted at F, to slide the shaft through rack teeth and a quadrant J. |
