Description: |
| Basic structure similar to the chain wrench in Stuart's parallel patent no. 1,933,513. This patent deals with the chain's attachment to the frame, and the shape of the "fittings" jaw structure.
This is the 3rd of three apparently related successive patents -- see also 1,933,512 and 1,933,513.
