Description: |
| The patent's claims include details of the ratchet structure, and an adjustable jaw supplemental piece. The latter piece was not included in corresponding U.S. patent 838,109.
A known example of the basic ratchet is apparently marked "PAT. OCT. 5 1905" - reflecting predecessor patent CA-95,354 - Oct. 3, 1905. |
