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. Kay subsequently accused Arkwright of stealing his work tools, and Arkwright made a counter-charge . The spinning machine as constructed in Nottingham by Kay and Arkwright was powered by
Spinning wheel cloth, his invention becoming known as the water frame. More modern spinning machines use a mechanical means to rotate the spindle, as well as an automatic method to draw out fibres, and devices to work many spindles together at speeds previously unattainable. Newer technologies that offer even faster yarn production include friction spinning, an open-end system, and air jets. Numerous types of spinning wheels exist, including the "great wheel" also known as "walking wheel" or "wool wheel" for rapid long draw spinning of woolen-spun yarns; the "flax wheel", which is a double-drive wheel used with a distaff for spinning linen;
