Description: |
| The primary adjustment is a spring-loaded slide with a tapered tip, that fits into gaps between thin plates in a slot in the shank of the movable jaw. The end of the spring is both a lifting means, and has a spur that fits into a notch in the frame to hold the adjusting slide in place. |
