Ring spinning is a method of spinning fibres, such as cotton, flax or wool, to make a yarn.

The ring frame developed from the throstle frame, which in its turn was a descendant of Arkwright’s water frame. The Saxony wheel was a double band treadle spinning wheel. The spindle rotated faster than the traveller in a ratio of 8:6, drawing was done by the spinners fingers. The water frame was developed and patented by Arkwright in the 1770s.

It was heavy large-scale machine that needed to be driven by power, which in the late 18th century meant by a water wheel. The throstle frame was a descendant of the water frame. It used the same principles, was better engineered and driven by steam. In 1828 the Danforth throstle frame was invented in the United States. The heavy flyer caused the spindle to vibrate, and the yarn snarled every time the frame was stopped. Jencks of Pawtucket, Rhode Island, who Richard Marsden names as the inventor. Machine shops experimented with ring frames and components in the 1830s.

At the time of the American Civil War, the American industry boasted 1,091 mills with 5,200,000 spindles processing 800,000 bales of cotton. The largest mill, Naumkeag Steam Cotton Co. The average mill housed only 5,000 to 12,000 spindles, with mule spindles out-numbering ring spindles two-to-one. After the war, mill building started in the south, it was seen as a way of providing employment. Almost exclusively these mills used ring technology to produce coarse counts, and the New England mills moved into fine counts.

Jacob Sawyer vastly improved spindle for the ring frame in 1871, taking the speed from 5000rpm to 7500rpm and reducing the power needed, formerly 100 spindles would need 1 hp but now 125 could be driven. This also led to production of fine yarns. During the next ten years, the Draper Corporation protected its patent through the courts. The Rabbeth spindle was self-lubricating and capable of running without vibration at over 7500 rpm.
