IBM Reproducing / Summary Punches

Type 513

Type 514

IBM 519

IBM 526

The class of machines variously called Reproducing Punches, Summary Punches, Gang Punches, and/or Document Originating Machines included the IBM 513 (date unknown) and 514 (1945) Reproducing Punches, the Type 516 (1932, intended as a Summary Punch for the 285), the IBM 519 Document Originating Machine (1946) (CLICK on any image to magnify), and the IBM 526 Printing Summary Punch. These machines performed a variety of tasks, according to the wiring of their control panels:

Reproducing	Copying all or selected information from one deck of cards to another deck of cards, possibly rearranging the fields.
Gang Punching	Copying information from one input card to many output cards.
End Printing	For example, of sequence numbers.
Verification	Of reproducing and gang punching results.
Summary Punching	Punching into a total or new balance card sums accumulated in an attached accounting machine such as the 403 (shown below) or 405 or 407.
Mark Sensing	Reading pencil marks from IBM cards and translating them into punches (optional feature).

Result decks did not have holes interpreted by printed characters across the top; that was the work of another machine called an Interpreter. All operations in the 513, 514, and 519 except summary punching are performed at 100 cards per minute.

The 526 is a unique hybrid: it's an 026 Card Punch and Summary Punch and Interpreter combined. It's slower than a dedicated Summary Punch (18 columns per second = 15 cards per minute) but it prints as it punches and it doubles as a key punch.
