Abstract
508,753. Shearing. STANDARD TELEPHONES & CABLES, Ltd., CLARKE, G. W., GRAY, F., and PELLATT, A. C. Sept: 16, 1938, No. 27082. [Class 83 (iv)] In a press for operating upon a blank, fingers 53 convey the blank from a feeding-in position A to a punching position B and fingers 52 then move the workpiece from the position B to a delivery shoot C. A sleeve 20 is reciprocated on a shaft 12 by a cam 16. The shaft 12 is rocked by a cam actuated lever 11. Arms 49, 48 are resiliently mounted on the sleeve and carry spring closed fingers 52, 53. The sleeve is moved by the cam 16 to position the fingers over the stations B, A and the arms 48, 49 are then rocked and the fingers grip the blanks. The arms are then swung upwards and are moved over the stations C. B. On depression of the arms the spring fingers are opened by fixed wedges. In a modification, suction caps are substituted for the spring fingers.
