Abstract

958,273. Selective punching machines. ELEKTRONISCHE RECHENMASCHINEN - WISSENSCHAFTLICHER INDUSTRIEBETRIEB - KARL - MARX - STADT VEB. March 10, 1961, No. 8844/61. Heading B4B. In punching record cards 35, the drive for the punches 10 is derived from a non-rotatable tubular member 2 mounted on two eccentrics 3, Fig. 3, of a drive shaft 1 which are counterbalanced by masses 5. The punches are driven from the member 2 by means of coupling members 8 and members 9 the lower ends 26 of which engage recesses in the punches. The members 8 are moved from the inoperative position, Fig. 1, to the operative position, Fig. 5, by the energization of electromagnets 19 the armatures of which are connected to lever arms 20 operatively connected through connecting rods 22 and bell-crank levers 27 to the members 8. The punches are returned after each punching operation by means of members 11, Fig. 1, or 14, Fig. 5, having pins 12 engaging in the members 9. The member 2, which may be subdivided perpendicular to its length, has connected thereto a spring-influenced arm which is oscillatable between two stops.
