Renold

Renold is a manufacturer of chain, gears and couplings. Its history page states that the Hans Renold Co. was established in 1879 following the purchase of the James Slater business, making Renold the oldest established transmission chain company still in existence in the world. The company introduced the patented solid bush in 1880, the origin of the bush roller chain. Its group head office is in Wythenshawe, Manchester, England.

According to Renold's company history page, in 1864 James Slater (later to become Hans Renold Co.) introduced the roller into chain; prior to this time transmission chain consisted of only pins and plates. In 1873, at the age of 21, Hans Renold, son of a burgher family in Aarau, Switzerland, came to England and found work in Manchester with a firm of machinery exporters. In 1879 his independent and inventive spirit found expression in the purchase of a small textile-chain making business in Salford; the Hans Renold Co. was established following the purchase of the James Slater business, which the page states makes Renold the oldest established transmission chain company still in existence in the world. In 1880 Hans Renold Co. introduced the patented feature of the solid bush, the origin of the bush roller chain, a design still used today throughout the world. In 1885 a patent for the block chain was applied for by Hans Renold, who decided to openly give his idea to the cycle trade for all to freely manufacture; Brampton Brothers Co., who later became part of the Coventry Chain Company (and ultimately Renold Chains Ltd.), experimented with self-lubricating bicycle chain. In 1888 Hans Renold Co. were riveting the bearing pins in the assembled chain, and in 1889 the company designed and manufactured a purpose built plate hole-punching machine.
