Abstract

6220. Buckley, C. March 12. Press knives.-A hollow punch for cutting- out circular, oval, or angular pieces from blocks or sheets of soft metal, wood, compressed fibre, or the like is made with substantially V-or U- shaped recesses in its cutting-edge, the bevel for producing the sharp edge being on the outer surface of the tool. Fig. 1 shows a punch for cutting-out a circular disk; its edge is formed with two V-shaped recesses 2, and cutting commences at the points 3 proceeding by a gradual action as the punch advances. Fig. 2 shows a punch for cutting-out rectangular pieces; the edge is in this case formed of a series of straight cutting-edges making up two approximately U- shaped recesses.
