A 19th-century trade article on the history and manufacture of fancy looms, centered on William and George Crompton and the Crompton Loom Works in Worcester, Massachusetts. It opens with a brief history of the loom, then covers Crompton's patented fancy loom, its first use at the Middlesex Mills in Lawrence, and later patents and improvements. It also describes the foundry and machine shops where the looms were built, and explains how the harness mechanism, pattern chain and drop-shuttle boxes distinguish a fancy loom from a plain cam loom.
