Patent specification (dated June 19, 1787, term expired) for a water- or horse-powered machine for spinning yarn from hemp, tow, flax, or wool. It was granted to John Kendrew, an optic glass-grinder, and Thomas Porthouse, a clockmaker, both of Darlington, County Durham. The text describes a large leather-covered cylinder with weighted pressing rollers, fluted drawing rollers, and a revolving cloth for feeding fibre. Together these produce a continuous sliver that is drawn finer in successive machines and then spun. A plate of patent drawings shows the frame and spindle assemblies.
