ResumoThe contributions of Elisha Root to development of metalworking technology in nascent mass-production industries in second quarter of 19th century are most commonly seen in light of his association with Colt Armory in Hartford, Connecticut, where, after 1849, he was factory foreman and general superintendent. In this capacity Root is credited with many innovations in techniques for manufacturing revolvers: He invented best form of drop hammer then in use, machines for boring, rifling, making cartridges, stock turning, splining, etc., and worked out whole system of jigs, fixtures, tools and gauges.' Few would dispute Joseph Wickham Roe's statement that the credit for revolver belongs to Colt; for way they were made, mainly to Root.2 Because of interest generated by Colt revolver-principally its method of manufacture-at time of Crystal Palace Exhibition in 1851, and because of enduring interest in genesis, development, and diffusion of system of interchangeable metal fabrication in several American industries, it would be desirable to know more about specific contributions of Root and, especially, how he acquired some of experience he later transferred to firearms industry. There are other reasons for interest in this mechanic's career.
