The main shank has rack teeth. The movable jaw has a toothed plate and a swinging lever. Swinging the lever out disengages the toothed plate allowing adjustment of the movable jaw. The entire movable jaw structure is prevented from falling off the shank by the side pieces for the handle. The specifications elaborate on the details of these main features. An apparently unused production example and elaborately made wooden model exist in a private collection.
