context_page_description: The spinning mule is a machine used to spin cotton and other fibres. They were used extensively from the late 18th to the early 20th century in the mills of Lancashire and elsewhere. Mules were worked in pairs by a minder, with the help of two boys: the little piecer and the big or side piecer. The carriage carried up to 1,320 spindles and could be 150 feet long, and would move forward and back a distance of 5 feet four times a minute.
  It was invented between 1775 and 1779 by Samuel Crompton. The self-acting mule was patented by Richard Roberts in 1825. At its peak there were 50,000,000 mule spindles in Lancashire alone. Modern versions are still in niche production and are used to spin woollen yarns from noble fibres such as cashmere, ultra-fine merino and alpaca for the knitware market.
  The spinning mule spins textile fibres into yarn by an intermittent process. In the draw stroke, the roving is pulled through rollers and twisted; on the return it is wrapped onto the spindle. Its rival, the throstle frame or ring frame uses a continuous process, where the roving is drawn, twisted and wrapped in one action.
context_section_description: The spinning inventions were significant in enabling a great expansion to occur in the production of textiles, particularly cotton ones. Cotton and iron were leading sectors in the Industrial Revolution. Both industries underwent a great expansion at about the same time, which can be used to identify the start of the Industrial Revolution.
  The 1790 mule was operated by brute force: the spinner drawing and pushing the frame while attending to each spindle. Home spinning was the occupation of women and girls, but the strength needed to operate a mule caused it to be the activity of men. Hand loom weaving, however, had been a man's occupation but in the mill it could and was done by girls and women. Spinners were the bare-foot aristocrats of the factory system. It replaced decentralized cottage industries with centralized factory jobs, driving economic upheaval and urbanization.
  Mule spinners were the leaders in unionism within the cotton industry; the pressure to develop the self-actor or self-acting mule was partly to open the trade to women. It was in 1870 that the first national union was formed.
  The wool industry was divided into woollen and worsted. It lagged behind cotton in adopting new technology. Worsted tended to adopt Arkwright water frames which could be operated by young girls, and woollen adopted the mule.
