Abstract

766,072. Punching. CATTELL, H. J. Feb. 2, 1955 [Feb. 15, 1954], No. 4395/54. Class 83 (4). A punching tool consists of two parallel spaced apart cantilever members 1, 2, a punch 8 and a die 12 mounted in the free ends of the members 1, 2 respectively, and a stripper 15 mounted on and movable along the punch 8 to strip the 'work therefrom. As shown, the members 1, 2 are the arms of a single U- shaped member. The stripper 15 has a flange 19 with a sloping edge 20 which, when the stripper plate 15 is rotated, engages the member 1 to move the stripper downwardly. In a modification, the stripper is a plate loosely mounted on the punch, a spring or a piece of rubber being interposed between the plate and the member 1. The die may be formed by a hole in the member 2, and the members 1, 2 may be separate members secured together at one end.
