VIIJENNY SPINNING FRAME Distinctive Characteristics Earliest contrivance for spinning a number of threadsand one which performs all three processes mechani-cally : a frame holding drive wheel, row of spindles, amoving carriage and row of rove bobbins; built onprinciple of Jersey wheel. First mechanical attenuating device for stretched rove:carriage receding from spindles. Twisting device: row of vertical spindles of the Jerseywheel type. Winding device : spindles and the returning carriage. Spinning intermittent. Outline Example: Hargreaves spinning — Spinning jenny. 52 YARN AND CLOTH MAKING I. frame supporting row of vertical spindles (Jerseywheel type), drive wheel, a moving carriageand creel of rove 19. — Cross Section or Hargreaves Jenny The Jenny here pictured is ready to draft and twist. The carriage is startingon its outward run with the rove clasped between the clove bars. As theleft hand moves the carriage outward towards the worker the rove be-tween the spindles and clove is drafted. Meanwhile the right hand anddrive wheel turn the spindles which twist the rove. 2. spindles with faller-wire at back of frame. 3. moving carriage with clove bars. 4. drive wheel turned by crank rotates spindles by means of band and — Right hand propels wheel (l3). Left hand moves carriage and faller-wire (earlier toe-managed faller-wire.) SPINNING TYPES 53 Motion — Intermittenf(ll, Hf)- 1. attenuating and twisting (compound process) 2. —Stretching by moving
