Title: Improvements in card punching machines
Filed: 1956-06-26
Abstract: 828,713. Selective punching machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 26, 1956 [June 29, 1955], No. 19714/56. Drawings to Specification. Class 31 (2). A statistical card punching machine of the kind described in Specification 684,273, which is referred to, is provided with additional circuitry whereby a first stepping switch is impulsed every time a field of a card has been manually keyed correctly while if an error is punched in a card after one or more fields have been punched correctly, then by closing an error switch, the error card will be advanced to a card read station to act as a storage device for the duplication of its correct field or fields into a new card at the card punch station, the duplication process advancing a second stepping switch step by step as each field is duplicated until the two stepping switches are in coincidence, whereupon the duplication process is terminated automatically, and the remainder of the statistical information is manually keyed into the card at the punch station. The advance of each stepping switch is controlled by an impulsing switch which is itself controlled by a programme card carried by a drum which is moved column by column in coincidence with the card at the read station. When a card has been punched without error it is released and the stepping switches automatically restored to their zero positions respectively.
