Description: |
| This application is a continuation in part of my application Serial No. 383,320, filed 14 March, 1941, now abandoned.
Claim:
Generally speaking a turning tool bit is mounted so as to be adjusted in a direction generally radially of the work. Such a tool is rather difficult to adjust accurately in that any variation in the position of adjustment will make a corresponding variation in the diameter of the turned surface. Furthermore, a turning tool on a Gridley or like tool slide is conventionally mounted in a manner to cause side thrusts to be transmitted to the slide and thus tend to twist the same on its stem. |
