Cotton-spinning machinery The spinning jenny is a multi-spool spinning wheel. It was invented circa 1764, its invention attributed to James Hargreaves in Stanhill, near Blackburn, Lancashire. The Water frame was developed and patented by Arkwright in the 1770s. The roving was attenuated (stretched) by drafting rollers and twisted by winding it onto a spindle. It was heavy large scale machine that needed to be driven by power, which in the late 18th century meant by a water wheel. Cotton mills were designed for the purpose by Arkwright, Jedediah Strutt and others along the River Derwent in Derbyshire. Water frames could only spin
Spinning frame a bobbin-and-flyer mechanism. The spacing of the rollers has to be slightly greater than the fiber length to prevent breakage. The nip of the roller pairs prevents the twist from backing up to the roving. Too large to be operated by hand, the spinning frame needed a new source of power. Arkwright at first experimented with horses, but decided to employ the power of the water wheel, which gave the invention the name 'water frame'. For some time, the stronger yarn produced by the spinning frame was used in looms for the lengthwise "warp" threads that bound cloth together, while
