text: The first stage of the spinning process is carding, initially this was done by hand, but in 1775 he took out a second patent for a water-powered carding machine and this led to increased output. He was soon building further mills on this site and eventually employed 1,000 workers at Cromford. By the time of his death in 1792, he was the wealthiest untitled person in Britain.
  The gate to Cromford Mill was shut at precisely 6am and 6pm every day and any worker who failed to get through it not only lost a day's pay but was fined another day's pay. In 1779, Arkwright installed a cannon, loaded with grapeshot, just inside the factory gate, as a warning to would-be rioting textile workers, who had burned down another of his mills in Birkacre, Lancashire.  The cannon was never used.
  The mill structure is classified as a Grade I listed building, it was first classified in June 1950.
