Object Details
- Description
- This cast-iron object has a metal base that holds, at the top front, a sheet of plastic with holes in it, marked with the categories of the 1890 U.S. Census of population. In back of this is a holder for a punched card. A long arm, pivoted at the back, extends over the card and the plastic sheet. It has two projections on it. One fits into holes in the plastic sheet and the other punches holes in the card.The action is similar to that of a pantograph - hence the device is called a pantograph punch.
- A mark on the plastic template reads: THE TABULATING MACHINE COMPANY, WASHINGTON, D.C. (/) System Patented January 8, 1889.
