Description: |
| Improvements to the automatic lathe of patent 1,252,928. The improvements provide improvements for the two-speed driving of the "main cam shaft" as well as improved operation and controlling of the blank transferring means from magazine to the lathe centers. A taper attachment is provided, and a speed lockout prevents the operator from changing speeds while the lathe is in operation. Finally, an improved stopping mechanism incorporates an emergency stop. |
