Sylvester, a hand operated turfer for removing props from the waste and moving other objects, consisting of a notched bar and lever operated ratchet, with chains attached at each end. During the late nineteenth century the commonest type of a fatal mine accident was a roof collapse caused by knocking out the pit props with a sledgehammer. In order to try and counter this problem, Walter Sylvester, who worked for a colliery in North Staffordshire, invented a ratcheted pulling device, which could be attached to the pit props by a long chain and used to haul them out without any danger to the operator. It could also be used for pulling trucks and other heavy items, and tightening-up cables. It was patented in 1895; known locally as a "Walter" it soon became widely used in mining and other industries as the "Sylvester".
