Abstract

602,720. Shearing. SANKEY & SONS, Ltd., J., and PERRY, A. J. Nov. 12, 1945, No. 30143. [Class 83 (iv)] In a flying shear the end of the rolled section to be sheared forms one of the contact points of a switch closing an electric circuit. The shear-blade C is mounted on a carriage D moved with the work by a cam E and is reciprocated by a crank e. The end of the stock contacts a lever K on a shaft k to close circuit through a battery T and coil s which closes a switch S. The latter closes circuit through a D.C. generator V and a solenoid G which trips an arm f throwing in the one revolution clutch of the shear. The sheared section is deflected laterally by a guide to allow the restoration of the parts. The D.C. generator may be driven by an A.C. motor v.
