Abstract
A tool for the cutting or coining of metal, including two jaws connected to parallel links by two jaw joint bolts. Two handles are connected to each other by a handle bolt and are connected to respective jaws by two middle bolts. Each jaw joint bolt is provided with an eccentric bearing surface situated between two coaxial bearing surfaces. The distance and parallelism of the jaws can be adjusted by producing rotating of the eccentric bearing surface by rotating one or more of the jaw joint bolts. The angular motion of the jaws is synchronized by a cylindrical roller retained axially between the links, and guided in a slot formed by overlapped fingers of the jaws.
