A one-page article from The Manufacturer and Builder describing James Lyall's positive-motion shuttle for power looms, made by J. & W. Lyall of New York. It explains the drawbacks of thrown shuttles (smashes, speed regulation, width limits) and how the carriage-driven shuttle avoids them, with mechanisms for shuttle and lay dwell. It also describes Lyall's looms shown at the Centennial, including a very wide loom for oilcloth foundations.
