Abstract of the Disclosure Shear apparatus for cutting large sheets of metal in- cludes a fixed blade, and a movable blade cooperable therewith. The movable blade is mounted on a movable plate having a plural- ity of circular apertures therein, the movable plate being dis- posed for sliding movement between two side support plates which are closely adjacent the movable plate. Discs are mounted in these apertures, the discs being eccentrically supported by pivots which are rotatably received in the adjacent support plates. The axes of the pivots providing the eccentricity are in the same angular relation to and the same angular relation from the centers of the discs. Arms are secured to the discs, and hydraulic means are provided for rotating the discs about their eccentric axis. Rotation of the discs lowers the movable plate between the two adjacent support plates to cause the blades mounted thereon to move past the fixed blade, shearing off a sheet inserted between the blades.
