Dictionary entry on the throstle, the continuous cotton spinning machine developed from Arkwright's water-frame of 1769. It explains how rovings pass through drawing rollers to flyer spindles, where the yarn is twisted and wound at the same time, and describes the mechanism that raises and lowers the bobbins. It contrasts the throstle with the mule, notes the uses of throstle yarn, and gives the origin of the name. Includes one sectional illustration (Fig. 6419).
