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
John Kay (spinning frame) collaborated in investigations of machinery for the manufacture of textiles, including the spinning of thread by means of rollers. By 1763 weaving was already automated, but spinning was still done by hand. Lewis Paul had made a machine using mechanical rollers in 1738, but this had not not been a commercial success. In 1767, Kay began a working relationship with Richard Arkwright, a wig-maker and entrepreneur. The character of this relationship, and in particular, the competing claims of Arkwright, Kay, and also Highs to primacy as inventors, were subsequently to become the subjects of bitter legal dispute (see below).
