Spinning jenny Spinning jenny The spinning jenny is a multi-spindle spinning frame, and was one of the key developments in the industrialization of weaving during the early Industrial Revolution. It was invented in 1764 by James Hargreaves in Stanhill, Oswaldtwistle, Lancashire in England. The device reduced the amount of work needed to produce cloth, with a worker able to work eight or more spools at once. This grew to 120 as technology advanced. The yarn produced by the jenny was not very strong until Richard Arkwright invented the water-powered 'water frame', which produced yarn harder and stronger than that of the initial
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
