A power loom is a mechanized loom, and was one of the key developments in the industrialization of weaving during the early Industrial Revolution. The first power loom was designed and patented in 1785 by Edmund Cartwright.

Northrop Automatic Loom James Henry Northrop , (8 May 1856 – 12 December 1940) was born in Keighley , West Yorkshire in the United Kingdom, where he worked in the textile industry. He emigrated to Boston , Massachusetts, in 1881.
The power looms also created a lot of vibrations, which forced them to be located on the lower level of the mills, or eventually in separate weave sheds, apart from the main mill buildings. In 1895, the Northrop Automatic Loom was patented in England, Belgium, Germany, Russia, Austria, and Spain. By 1900, Draper had sold over 60,000 Northrop Looms.
British Northrop Loom Co Ltd was an engineering firm based in Blackburn, Lancashire, England. The company manufactured machinery for producing textiles, particularly the Northrop Loom. [1] It expanded rapidly around the time of the First World War, and by the 1950s it exported over 10,000 machines annually worldwide. [2]
[5] At this point the loom has become fully automatic, this is the Kenworthy and Bullough Lancashire Loom. The Cartwight loom weaver could work one loom at 120–130 picks per minute- with a Kenworthy and Bullough's Lancashire Loom, a weaver can run up to six looms working at 220–260 picks per minute- thus giving 12 times more throughput.
This process is called taking up. At the same time, the warp yarns must be let off or released from the warp beam, unwinding from it. To become fully automatic, a loom needs a tertiary motion, the filling stop motion. This will brake the loom if the weft thread breaks. [4] An automatic loom requires 0.125 hp to 0.5 hp to operate (100W to 400W).
William Radcliffe (1761?, in Mellor, Derbyshire – 20 May 1842, in Stockport [1]) was a British inventor and author of the essay Origin of the New System of Manufacture, Commonly Called Power Loom Weaving.
