Hollerith Gang Punch
This card punch machine was patented on August 1, 1916 by inventor Herman Hollerith. It was produced by the Tabulating Machine Company of New York City. A later version of this machine was produced by the British Tabulating Machine Company of London but it lacked the most striking features of the earlier version, those being the brass top and levers.
