opposition to the machine caused hargreaves to leave for nottingham, where the cotton hosiery industry benefited from the increased provision of suitable yarn. in nottingham hargreaves made jennies for a man named shipley, and on 12 june 1770, he was granted a patent, which provided the basis for legal action (later withdrawn) against the lancashire manufacturers who had begun using it. with a partner, thomas james, hargreaves ran a small mill in hockley and lived in an adjacent house. the business was carried on until his death in 1778, when his wife received a payment of £400. when samuel crompton invented the spinning mule in c.1779, he stated he had learned to spin in 1769 on a jenny that hargreaves had built.
