Description: |
| Improvement to wrench of the type in patent no. 698,780, to allow the chain to pass to either side of the center line of the handle regardless of which "face" of the toothed jaw was engaging the work. The construction includes alternate provisions for allowing the chain sufficient "free play" to allow the chain to swing to either side of the handle and head.
