Abstract

711,331. Shearing. FERRANTI, A. Sept. 17, 1952 [April 11, 1952; July 30, 1952], No. 23379/52. Class 83 (4) In a reciprocating blade shear with movable upper blade C co-operating with a fixed lower blade B, a tubular light source H is adjustably positioned between the beam D and a hold-down G to throw the shadow of the blade C on to the workpiece to facilitate setting. A screen I or a wire may be fitted to improve the image.
