Abstract
614,335. Punching. SCHULER, G. H., and SCHULER, V. A. May 15, 1946, No. 14673. [Class 83 (iv)] A hand-operated punching- tool comprises a bolster 21 having a screwed spigot 27 supporting a carrier 34 with a thrust race 33 and a thrust element 31 acting as a punch co-operating with a ring die supported by the bolster. Operation. The carrier 34 is rotated by tommy-bar or spanner and drives the punch 31 axially, without rotation through the material, supported on the ring die. The ring dies are of several sizes and the element 31 may support corresponding punches 41, Fig. 5 (not shown). The carrier skirt is milled for finger rotation and the element 31 may have a key engaging a spigot slot. In a modification the thrust element 31 and carrier are held together by spring clips, the dies fit a bolster recess and the bolster has holes for a waste and dieejecting tool. The holes punched may be of circular or other shape.
