Salford is credited as the birthplace of the Bush Roller Chain. Hans Renold, a Swiss-born engineer, came to Salford in the late 19th century. In 1879 he purchased a small textile-chain making business in Ordsall from James Slater and founded the Hans Renold Company, what is now Renold, a firm which still produces chains. Renold invented the bush roller chain shortly after and began producing it. It is the type of chain most commonly used for transmission of mechanical power on bicycles, motorbikes, to industrial and agricultural machinery to uses as varied as rollercoasters and escalators.
