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. [1] It was refined over the next 47 years until a design by the Howard and Bullough company made the operation completely ...
The Northrop Loom was a fully automatic power loom marketed by George Draper and Sons, Hopedale, Massachusetts beginning in 1895. It was named after James Henry Northrop who invented the shuttle-charging mechanism.
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.
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).
[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.
The firm of Howard and Bleakley was founded in 1851 with four workers; [1] in 1856 Bleakley retired and the partnership was changed to Howard & Bullough. John Bullough had perfected a self-acting temple on his handloom, and with William Kenworthy at Brookhouse Mills had been responsible for the Lancashire Loom. [2]
