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
Ring spinning this was the standard spindle, and William Draper spent much of his time in court defending this patent. The new method was compared with the self-acting spinning mule which was developed by Richard Roberts using the more advanced engineering techniques in Manchester. The ring frame was reliable for coarser counts while Lancashire spun fine counts as well. The ring frame was heavier, requiring structural alteration in the mills and needed more power. These were not problems in the antebellum cotton industry in New England. It fulfilled New England's difficulty in finding skilled spinners: skilled spinners were plentiful in Lancashire. In
