Abstract

204,506. Adams, T. H. Sept. 8, 1922. Selective perforating machines. - A handactuated appliance with two punches has one punch adapted to be slid laterally in order to vary the distance between the perforations. Side frames 1, united by a channel 2, forming the die, and a tie rod 3, carry an operating handle 23 and a slot-guided channel-shaped head 19. A metal strip 9, 10, 11, bent to the shape shown, can be slid on the rod 3 and ends in a lug 12 abutting against one side of the channel. One of the punches is mounted resiliently in the strip 9, 10 which is held in adjusted position by a detent 22. The other is mounted in a similar fixed strip. The papers to be perforated are placed in an opening 13.
