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 mule end. In the 1920s much attention was given to this problem. Mules had used this mixture since the 1880s, and cotton mules ran faster and hotter than the other mules, and needed more frequent oiling. The solution was to make it a statutory requirement to only use vegetable oil or white mineral oils, which were believed to be non-carcinogens. By then cotton mules had been superseded by the ring frame and the industry was contracting, so it was never established whether these measures were effective.
