Abstract

612,900. Shearing. GREENHALGH, J. June 5, 1946, No. 17049. [Class 83 (iv)] In a pivoted blade shearing-machine the blade e is actuated by a link j on the downward movement of a lever g and the machine is fed over a stationary workpiece by a pawl m on the lever g engaging a ratchet l on a sprocket k meshing with a stationary chain s. The machine is mounted on a carriage a slidable on a base b carrying work clamps, not shown. The pawl m may be held inoperative by a screw m<SP>2</SP>.
