James Hargreaves James Hargreaves James Hargreaves (c. 1720 – 22 April 1778) was a weaver, carpenter and inventor in Lancashire, England. He was one of three inventors responsible for mechanising spinning. Hargreaves is credited with inventing the spinning jenny in 1764, Richard Arkwright patented the water frame in 1769, and Samuel Crompton combined the two creating the spinning mule in 1779. James Hargreaves was born at Stanhill, Oswaldtwistle in Lancashire. He was described as "stout, broadest man of about five-foot ten, or rather more". He was illiterate and worked as a hand loom weaver during most of his life. He married and
John Kay (spinning frame) collaborated in investigations of machinery for the manufacture of textiles, including the spinning of thread by means of rollers. By 1763 weaving was already automated, but spinning was still done by hand. Lewis Paul had made a machine using mechanical rollers in 1738, but this had not not been a commercial success. In 1767, Kay began a working relationship with Richard Arkwright, a wig-maker and entrepreneur. The character of this relationship, and in particular, the competing claims of Arkwright, Kay, and also Highs to primacy as inventors, were subsequently to become the subjects of bitter legal dispute (see below).
