Power — Hand ; later horse ; water for most of work. Hand and knee managed carriage and the winding — Intermittent with three separate movenients(11, llh). SPINNING TYPES 6i 1. Attenuating. 2. Attenuating and twisting. Twisting. 3. Winding. Process — Attenuating first by drawing rollers andsecond through stretching by receding car-riage (12).. Fig 24. — Cross Section of Hand Mule Upper right, drawing rollers attached to frame. Center, moving carriage withspindles. Upper left, propelling hand wheel. Twisting by spindles. Winding by spindles and returning carriage. 1. Rove bobbins placed on creel, carriage in front of rollers. 2. A short stretch of rove drawn from bobbins through drawing rollers to slightly faster recedingcarriage with slowly rotating spindles (8, 8i,9, 9d, g). 62 YARN AND CLOTH MAKING 3. Rollers stop delivering rove and hold fast, spindles rotate more rapidly while carriageslackening pace continues to end of course. 4. Carriage backs a short distance to reheve strain on yarn; spindles add more twist. 5. Spindles stop; faller-wire drops carrying yarn from spindle tip to winding position (10, lOe). 6. Yarn wound on rotating spindles as carriage returns to first position. Economic Gain In production: Spindles of Jenny transferred from standard to car-riage. Improved moving carriage. A loss in speed from Water
