Description: |
| "I am aware that lathe-chucks have heretofore been devised in which a scroll-shaped cam provided with worm-teeth was made to operate the jaws, the cam being operated by a screw-key or worm; but I am not aware that any have been heretofore devised in which a detachable screw-key engaging with worm-teeth on a central core has been applied in holes on opposite sides of the shell for tightening or loosening the grip." |
