Description: |
| This patent describes the PERFECT HANDLE adjustable end wrench. The main claim of the patent is that the parts can be formed by drop forging without additional machining. The patent drawing shows the "S" handle version; contemporary ads indicated the straight handle version is based on the same patent. Thomson's Jan. 5, 1915 patent (no. 1,123,423) applies to late production versions of this tool. |
