Title: Shear mounting for corner shearing machine

Abstract: A corner shearing machine has two pairs of shears, the lower blade of one pair intersecting the lower blade of another at a right angle, and the upper blade of one pair intersecting the upper blade of the other pair at a right angle, the lower blades being mounted to a base and the upper blades to a reciprocable ram. Adjusting wedge assemblies, with screw drives and manually operable cranks facilitate adjustment of blade clearance, and hydraulically energized pressure pads maintain zero clearance between ram guide slides and guideway blocks therefor. Ram drive is by one or another of two hydraulic cylinders operating through a rocker shaft and linkage connected to the ram, and hydraulic clamps secure the work.
