Abstract

238,568. Kline, F. J. June 30, 1924, [Convention date]. Reciprocating-punch machines.-A paper-punch has a base 1 with vertical lugs 2 carrying bosses guiding spring-retracted punches 4 pivoted to the arms of a lever 6 pivoted, with play, to the lugs 2. The base 1 carries a die-plate 5, and, beneath an extension, slides an edge gauge formed of a strip 19 with upstanding lugs 20 locked in adjusted position by a pivoted spring- urged detent 24. The edge gauge is frictionally held in adjusted position at a number of points by a screw engaging the die-plate extension, by external springs, or as shown in Fig. 7, by corrugations in the strip 19. Specification 236,162 is referred to.
