John Kay (spinning frame) a spinning machine embodying the ideas which they had been developing. Arkwright patented it 1769 without mentioning Kay, his "workman". Kay learned of this patent from another Nottingham inventor, James Hargreaves, and told Hargreaves that it was he, Kay, who was the real inventor. Arkwright accused Kay of revealing the design to Hargreaves, and the two fell out. Kay left Arkwright's Nottingham house, where he had been living, ending their relationship.
