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
