John Kay (spinning frame)
John Kay was a clockmaker from Warrington, Lancashire, England, associated with the scandal surrounding invention of the spinning frame in 1767, an important stage in the development of textile manufacturing in the Industrial Revolution. Kay constructed the first known frame, and is one of the claimants to having been its inventor. He is sometimes confused with the unrelated John Kay who had invented the flying shuttle thirty years earlier.
== John Kay and Thomas Highs ==
In 1763, Kay was a married clockmaker in Leigh. His neighbour, Thomas Highs, was an inventor, and the two collaborated in textile-machinery experiments. Exactly what technologies, and contributions the two men worked on then became the subject of several controversial court cases, but among other things, Kay and Highs probably investigated textile-spinning by means of rollers.〔 But drawing of the Highs design from this time "reveal vital differences which show that despite his great mechanical abilities he was unable to develop the finer points of roller spinning". In any case, these drawings (and all documentation of the 1764 research) are of uncertain authenticity because they were presented long after the fact, by Highs and his advocates.〕
(By 1763 weaving had been greatly automated, but spinning was still done by hand wheel. Research into using mechanical rollers to replace hand spinning had started in the first half of the century; Lewis Paul had the first model in 1738, but further development was needed to make it profitable.)
Though they made many trial machines, these three years of research were limited by their lack of capital, and they were unable to perfect any designs.〔
