Addressograph
An addressograph is an address labeler and labeling system. In 1896, the first U.S. patent for an addressing machine, the Addressograph was issued to Joseph Smith Duncan of Sioux City, Iowa. It was a development of the invention he had made in 1892. His earlier model consisted of a hexagonal wood block onto which he glued rubber type which had been torn from rubber stamps. While revolving, the block simultaneously inked the next name and address ready for the next impression. The "Baby O" model was put into production on July 26, 1893, in a small back room of the old Caxton Building in Chicago, Illinois. The original company which manufactured the Addressograph, Addressograph International, merged in 1932 with American Multigraph of Cleveland, Ohio, to form the Addressograph-Multigraph Corporation manufacturing highly efficient addressograph and duplicating machines. In 1978 the corporate headquarters moved from Cleveland to Los Angeles, California, and the corporation name changed in 1979 to AM International, later AM Jacquard Systems (after acquiring Jacquard Systems). In 1982, the firm filed for bankruptcy under Chapter 11.…
