Abstract
134,372. Wood & Co., E., and Rothwell, W. E. Nov. 18, 1918. Punching; punches. -Relates to machines for punching two or more holes simultaneously and consists in means for adjusting the pitch of the holes. A holder A for a pair of punches D is secured by a stem a to the plunger of the machine. In the holder are a pair of recesses a<1> to receive the punchbodies which are eccentric to the punches proper. By rotating one or both of the punches, the pitch is adjusted, and the punches are then locked by lugs d fitting notches in the holder. In a modification, the punch bodies are co-axial with the punches and are surrounded by eccentric sleeves which are rotated to vary the pitch. The dies F are eccentric so as to be capable of adjustment to suit the punches.
