Description: |
| The wrench appears to be an evolution of York's Dec. 7, 1920 patent (no. 1,361,130).
The focus of the patent is the handle structure and the connections between the components. The universal joints are the focus of York's parallel patent (no. 1,498,712).
A 1927 TRUTH TOOL Co. (Mankato, MN) shows YORK socket sets with features corresponding to these patents.
