Description: |
| Claim:
The first part of my invention is found in that part of engravers ruling-machines known o us the pawl attachment, which turns the ratchet-wheel and the main screw. It consists of limiting the movement of the pawl on its hinge sufficiently to just clear the teeth of the wheel in the reverse movement of the pawl-handle, the pawl being pressed out of engagement with the teeth by the finger against a stop. |
