(p. 239) Cartwright constructed twenty looms using his design and put them to work in a weaving “shed” in Doncaster. He further agreed to license the design to a cotton manufacturer named Robert Grimshaw, who started building five hundred Cartwright looms at a new mill in Manchester in the spring of 1792. By summertime, only a few dozen had been built and installed, but that was enough to provoke Manchester’s weavers, who accurately saw the threat they represented. Whether their anger flamed hot enough to burn down Grimshaw’s mill remains unknown, but something certainly did: In March 1792, after a series of anonymous threats, the mill was destroyed.
Cartwright’s power looms were not the first textile machines to be attacked, and they would not be the last.
