| The main shank and base for the adjusting screw are in one piece. The shank is notched to fit around the nut portion of the adjusting screw. The movable jaw is formed of a second piece with the "back" side opened; it is closed around the shank and pinned or closed with a clamping screw.
The patent was used for the SOLID BAR and SOLID STEEL nut wrenches produced by Peck, Stow and Wilcox, and also marketed under such brand names as KEEN KUTTER, etc.
