Description: |
| The patent is for the "encased joint" which would allow for a cutting notch to extend almost to the center of the pivot, unless a center pivot pin was incorporated into the joint.
Pliers incorporating this principle were announced in hardware trade journals in mid-1915.
The bearing surfaces of the end-cutting pliers in pat. no. 1,192,021 conform to the concepts in this patent. |
