MOSELEY, CHARLES S. Mr. Moseley has been intimately connected with nearly every watch company in the United States, and as a mechanical engineer and designer of watch machinery, of the automatic type, he had no superiors and but few equals. Among those that have acquired a world-wide reputation may be mentioned the interchangeable stem-wind mechanism of the Elgin National Watch Company; the dust-band used by the same company, the best and cheapest ever made; the triangular hairspring stud; a patent regulator and the split chuck, an accessory now become universal and indispensable to every watchmaker in the land. He was born at Westfield, Mass., Feb. 28 1838. His first connection with watchmaking was in 1852, when he entered the employ of Dennison, Howard & Davis, at Roxbury, Mass. He followed the factory to Waltham and was employed in the capacity of foreman of the machine shop and later as master mechanic. In 1859 he became master mechanic of the Nashua Watch factory, and designed and built the machinery with which that watch was manufactured. In 1864 he joined the Elgin National Watch Company, then just starting, and was made general superintendent, in which capacity he remained with the company until 1877.
