ADAMS, Isaac (1803-83). An American inventor. He was born at Rochester, N. H. He was at first an operative in a cotton factory and afterward a cabinet maker, and in 1824 began work in a Boston machine shop. In 1828 he invented the printing press now known by his name, and in 1834 greatly improved it. The original feature of the press was the elevation of a flat bed against a stationary platen. Mr. Adams was a member of the senate of Massachusetts in 1840.
