Description: |
The focus of the patent is the shiftable pawl and the manipulator which changes its position. A major concern is the transfer of strain from the driven member to the frame enclosing the ratchet mechanism. Two teeth on the pawl engage teeth on the driven member.
This patent is noted in patent nos. 2,772,763 and D173,830.
This wrench appears in mid-1930s through late-1940s catalogs as the WILLIAMS S51 SUPERRATCHET; according to Alloy-Artifacts the wrench was put into production in 1933 and continued through WWII.
