Two-page dictionary entry on the shuttle from Knight's American Mechanical Dictionary. It defines the loom shuttle, notes John Kay's 1735 invention of the fly-shuttle, and describes several patented loom-shuttle varieties: hinged spindle, guide-wire, tension device, compressed-air thrown, roller-driven and Lyall's positive-motion loom. It also covers sewing-machine shuttles (Singer, Howe) with illustrated tension and bobbin-bearing designs.
