1784, Jun 81879, Feb 5
a United States inventor and author. About 1832 he devised the first stop motion to the drawing frame, which afterward was used both in the United States and England. In 1832 he patented the steam cylinders and connections which became universally used in dressing frames for drying yarns. His greatest invention was the dynamometer used for ascertaining the power for driving machinery. It was first used in the York Co. mills in 1837, and was considered preferable to any known apparatus for determining the power actually used in driving machinery. In early life he contributed to the Boston Monthly Anthology and to the Port Folio.
