Abstract

23,958. Newman, A. S. Oct. 19. Reciprocating-punch machines. - Relates to the type of perforating-machine in which the distance between the perforations is governed by an adjustable pin which enters the perforation previously made. Fig. 2 is an inverted plan of the device. The controlling-pin d is mounted on a plate spring a secured at one end to the reciprocating head b carrying the punch or punches c. The spring a is adjusted by a screw f bearing on its free end, and the flexibility of the spring may be increased by reducing it in width or thickness towards the free end. The spring is preferably curved slightly, as shown in Fig. 3, so that the adjusting-screw tends to straighten it.
