Description: |
| Walter L. Schlegel jr. - patent attorney
Amsted Industries, Inc. owned South Bend Lathe Works.
My invention relates to locking means and more particularly to means for locking a face plate or other threaded member onto the spindle of a lathe or the like. In various machine tools, a faceplate or other threaded member is threaded onto a spindle. If a braking force is applied to the rotating spindle having such a member threadably secured thereto, a danger exists of the member unscrewing itself from the spindle because of the member's momentum. The member may be secured to the spindle by means of a pin or a setscrew however, this method has the disadvantage of taking considerable time to assemble and disassemble. An object of this invention is to provide a simple arrangement on the threaded member to accommodate threading of the member onto the spindle but automatically locking to prevent removal of the member therefrom. The danger of the member becoming unscrewed from the spindle when a brake is applied is therefore eliminated. Another object of this invention is to provide a simple means to disable the automatic locking arrangement to facilitate removal of the member from the spindle, when required. |
