Description: |
| The approaching movement of the jaws is similar to that in the "SUPERIOR" (viz. patent no. 933,096) and "ROBERT" / "HOE" (viz. patent no. 1,407,578). In those patents the attachments between the jaws are separate side bars, rather than the combination of pivots and slide in this patent. |
