Dictionary entry from Knight's New Mechanical Dictionary describing a spooling machine that winds silk thread onto 100-yard, 200-yard or one-ounce spools. It explains the row of eight small winding units, the guide-rod, main shaft and finger-rod, the hoppers that feed empty spools, the measuring gauge that stops, nicks and cuts the thread at 200 yards, and the reversing-screw and jaw mechanism that varies the traverse as the spool fills. Includes one engraving (Fig. 2322) and references to Scientific American articles.
