Abstract

143,122. Taylor, G. Sept. 18, 1919. Punches. - An adaptor a for a. punching-press, to enable various sizes of punches f, made from bar stock to be used, is formed externally to fit the holder on the press ram, and internally at d to take bushes e for various sizes of punch f. In one form, Fig. 2, bushes fitting the punch internally and the hole d externally, and having a hole g to allow the clamping-screw i to pass, are used. In another form, Fig. 4, the punch is inserted into the bush j from the back, and riveted over slightly, as shown, to prevent it from dropping out.
