Abstract

637,841. Shearing. UNITED ENGINEERING & FOUNDRY CO. Dec. 22, 1947, No. 33788. Convention date, Nov. 9, 1940. [Class 83 (iv)] Straightening.-In a reciprocating blade flying shear, the upper blade 6 is carried on a frame 5 reciprocated by an eccentric 3 on a drive-shaft 15. The lower blade 9 is mounted on a carrier 8 guided in the frame 5 and reciprocated by a cranked portion 1 of the shaft 15. The frames are swung about the shaft 15 by rods 22 oscillated by cranks 24 on a shaft 25. To allow for variation of stroke of the frame to provide non-cutting strokes an eccentric 36 rotated from a shaft 44 is interposed between the frame 5 and the crank 1. When the shafts 15, 44 are rotated with the eccentric 36 in the setting shown in Fig. 1, cutting takes place with the cutters moving in closed paths. When the eccentric 36 is rotated the throw of the crank 1 is periodically reduced to prevent shearing. The mechanism is driven by an electromotor 16 through change-speed gearing. The sheets are fed from a roller leveller R and on guide 12 and are fed away by a belt 28. U.S.A. Specification 1,973,515 is referred to.
