Lombe's Mill
Thomas Cotchett built the first mill in Derby in 1704, but it was unsuccessful. So John Lombe visited Piedmont in 1716 to see the successful silk throwing mill there. This was an early example of industrial spying. He returned to Derby with the knowledge and a group of Italians. He and his half brother Thomas Lombe (born 1685) instructed George Sorocold to build a mill to his design and fitted it with the new machines. It was built to the south of Cotchetts Mill. Thomas Lombe was given a 14 year patent to protect the design of the throwing machines he used. This displeased the King of Sardinia, and he stopped exporting suitable raw silk. It is speculated that he was responsible for John Lombes mysterious death six years later in 1722. His elder brother, Thomas Lombe took over the business. When the patents lost effect in 1732, other mills were built in Stockport and Macclesfield. To the north of the powered Italian Works an unpowered Doubling Shop was built- this happened before 1739. The mill was sold in 1739 to Thomas Wilson, and an inventory of this time is  still exists.
