Description: |
| A toothed piece inside the movable jaw is jammed against matching fine rack teeth on the main bar to hold the adjustment. A toggle inside the jaw generates the jamming action, and is a focus of the patent.
The specifications demonstrate the parallel evolution of British and American vocabulary -- by treating "spanner" and "wrench" as synonyms.
Corresponding British patent GB-187800445 was registered February 2, 1878. |
