The Lancashire Loom was a semi-automatic power loom invented by James Bullough and William Kenworthy in 1842. Although it is self-acting, it has to be stopped to recharge empty shuttles. It was the mainstay of the Lancashire cotton industry for a century.
John Bullough (1800–1868) was from Accrington, often described as a simple-minded Westhoughton weaver. Originally a handloom weaver, unlike others of his trade Bullough embraced new developments such as Edmund Cartwright's power loom (1785). While colleagues were busy rejecting new devices such as in the power-loom riots that broke out in Lancashire in 1826, Bullough improved his own loom by inventing various components, including the "self-acting temple" that kept the woven cloth at its correct width, and a loose reed that allowed the lathe to back away on encountering a shuttle trapped in the warp. Bullough also invented a simple but effective warning device which rang a bell every time a warp thread broke on his loom. Bullough moved to Blackburn and worked with William Kenworthy at Brookhouse Mills, with whom he applied his inventions to develop an improved power loom that later became known as the "Lancashire Loom".[1] He was forced to quit Blackburn, for fear of angry handloom weavers. He later settled in Accrington to form Howard & Bullough in partnership with John Howard at Globe Works in Accrington alongside the Leeds-Liverpool Canal in Accrington. Here he invented the slasher, which founded the company's success. He was one of the country's largest manufacturers. At the height of the business the Globe works employed almost 6000 workers and covered 52acres. 75% of production was exported.[2] Howard and Bullough became part of the Textile Machinery Makers Limited group, which were bought out by Platt, and in 1991 the company name changed to Platt Saco Lowell. The Globe works closed in 1993. [3]
From 1830 there had been a series of incremental improvements to the basic Roberts Loom.
There now appear a series of useful improvements that are contained in patents for useless devices
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. The power loom is now referred to as "a perfect machine", it produced textile of a better quality than the hand weaver for less cost. An economic success.Other improvements were the
The three primary movements of a loom are shedding, picking, and beating-up.
The principal advantage of the Lancashire loom was that it was semi-automatic, when a warp thread broke the weaver was notified. When the shuttle ran out of thread, the machine stopped. An operative thus could work 4 or more looms whereas previously they could only work a single loom. Indeed, the term A Four Loom Weaver was used to describe the operatives. Labour cost was quartered. In some mills an operative would operate 6 or even 8 looms, although that was governed by the thread being used. By 1900, the loom was challenged by the Northrop Loom, which was fully automatic and could be worked in larger numbers. The Northrop was suitable for coarse thread but for fine cotton, the Lancashire loom was still preferred. By 1914, Northrop looms made up 40% of looms in American mills, but in the United Kingdom labour costs were not as significant and they only supplied 2% of the British market.
