Description:
The distinctive feature of this wrench is the rocking jaw face with the lever on the movable jaw. The adjusting ring turns on teeth segments cut in the corners of the rectangular shank. The Barnes Tool Company marketed this wrench in standard sizes; late 19th Century catalogs show 10 inch, 14 inch and 18 inch sizes.
