A short 1877 magazine article describing Lyall's corset-weaving and bag-weaving looms shown at the Centennial Exhibition. The corset loom combines power-loom principles, Lyall's positive shuttle motion and Jacquard cards to weave four shaped corset webs at once, and the bag loom weaves four seamless bags at a time as double cloth. It notes production figures at a New York factory and includes an engraving of the Lyall looms in operation.
