Hollerith Pantograph Punch



Punch Machine

The Hollerith Pantograph Punch, also known as the Hollerith Pantotype Punch or Hollerith Keyboard Punch, was patented in 1892 by Herman Hollerith of Washington, D.C. It was produced by his company, the Tabulating Machine Company, which was incorporated in New York. The Pantograph Punch was used for tabulating by way of cards that were punched cards. At the front of the machine was a large, master index from which the user would select and duplicate via a pointer where, on a card resting in the middle of the machine, the punch should be made. It proved especially useful in census taking and in the medical industry.
