Eleazer Jenks built a machine shop at Pawtucket in 1813 for heavy forging and for the manufacture of spinning machinery, which was occupied by David Wilkinson for many years.[141] The same year, Larned Pitcher also started a shop there, and soon took in P. Hovey and Asa Arnold. In 1819 Ira Gay was taken in, and the firm became Pitcher & Gay, one of the largest manufacturers of cotton machinery. Gay remained in Pawtucket until 1824, when he went to New Hampshire in connection with the Amoskeag Manufacturing Company and the Nashua Manufacturing Company, then just starting.[142] A few years later Ira Gay and Zeba, his brother, started a shop at North Chelmsford for building textile machinery. With the growth of the Merrimac textile interests, this plant became very influential and is running today. The firm has changed several times with the deaths of various partners, and is now known as the North Chelmsford Machine & Supply Company. It has preserved many of the old tools used in the early days, and there are few shops of greater historical interest in this country. [141] Goodrich, p. 64. [142] _Ibid._, p. 66. Capt. James S. Brown, son of the Sylvanus Brown referred to, who had worked for David Wilkinson in 1817, succeeded Ira Gay in the Pawtucket shop, the firm becoming Pitcher & Brown. In 1842 Brown became sole owner and greatly enlarged the works. The shop which he built in 1847 was 400 feet long and employed over 300 workmen. Brown lived for many years and made many valuable inventions, which included a beveled gear cutter, boring machine, grinder, improvement in the Blanchard type of lathe, and many improvements in textile machinery. Some of the lathes which he himself built in 1820 were in use for seventy years.[143] [143] _Ibid._, pp. 71-72. Col. Stephen Jenks started a shop in 1820 for the making of nuts and screws, which later became the William H. Haskell Company of Pawtucket. Alvin Jenks, of Stephen Jenks & Sons, went to Central Falls in 1829 and the next year entered into partnership with David G. Fales. This firm, known as Fales, Jenks & Company, built cotton machinery for many years, and moved to Pawtucket in 1865.[144] The Jenkses of the Fales & Jenks Machine Company, as it is known now, are lineal descendants of the original Joseph Jenks of Lynn.
