Abstract

245,364. August, J. R. C., and Hunter, E. K. March 3, 1925. Selective punching- machines.-An automatic punching machine for perforating in code paper and like strips comprises a master electroma,gnet 20 which operates a striker 4, and a number of electromagnets 12, 14 &c. operating arms 9 carrying abutments 8 adapted to be interposed between the striker 4 and the punches 5; when a particular key, for example, the key 18 is depressed, the corresponding magnet 12 and the master electromagnet are connected in series, but the master electromagnet has a time lag as compared with the other magnet so that the arm 9 is actuated prior to the striker. The electromagnets 12, 14 &c. may be provided with protective shunt resistances 22. The action of the magnets 12 &c. may be made quicker than that of the electromagnet 20 by arranging their armatures nearer the cores, by making their cores larger or more permeable as compared with the loads, or the windings may have different resistances or numbers of turns.
