Description: |
| This is an improvement to the earlier E. Wright patent (#69,292 - 9/24/1867), which adds a quick-adjust nut to the adjustment mechanism. If the caliper legs are squeezed, the nut releases and can be slid to any point on the threaded rod.
Known examples are marked with the manufacturer's name and patent date. |
