DS as president, two pages, 11.5 x 15.5, July 1, 1836. Patent papers issued to Cyrus Alger for the manufacturing of “cast iron sheeves for blocks for vessels and for other purposes where sheeves of pulleys are used.” Countersigned by Secretary of State John Forsythe and Attorney General B. F. Butler. The second page, written by Alger, details the design and purpose of his invention. Alger, the best practical metallurgist of his time, obtained numerous patents that improved processes in the continued advancement of ordnance. In 1809, he established the Cyrus Alger Iron Company in South Boston; by 1850, his company was the largest foundry in the country. During the War of 1812, he supplied the government with large numbers of cannon balls, and his works became famed for the excellent ordnance they manufactured. During the American Civil War, his model M1835 was present in almost every campaign and was used in every major engagement. Many Cyrus Alger cannons are now displayed in museums, on battle fields, and at memorials and monuments, and reproduction models are even ised for Civil War reenactments. In very good condition, with intersecting folds, one through a single letter of signature, some scattered creases and moderate wrinkling, and a mild shade of overall toning. The white wafer seal with green ribbon is worn but intact, and Jackson’s signature measures an impressive 6″ long. JSA/John Reznikoff Auction LOA and RRAuction COA.
