Description: |
| The movable jaw fits loosely on the pivot pin so that the strain is borne by the heavy boss resting in a socket in the main bar. A tension spring holds the jaw in its operational position. The design was intended to be manufactured and sold with several sizes of movable jaws supplied with one shank. |
