Description: |
The patent is for a modification of the chain wrench described in pat. no. 876,926 to accommodate "cable chain." The connecting point for the chain is further up the handle. The holes for bolts to connect the jaw plates to the handle are relocated. The hook for the free end of the chain is also modified.
The double-ended jaw pieces are of the form used in Williams' VULCAN BI-JAW chain wrenches which were introduced in spring, 1910.
