Description: |
| Facing jaws on adjacent pivot points are moved together or apart as the handle is shifted. The pivot pins are threaded bolts so the jaws can be re-positioned to change the size range.
The wrench received Canadian patent no. CA-62,580 on Feb. 7, 1899.
The design resembles the Ashworth's contemporary patent (no. 627,466). |
