Abstract
A conveyor comprising a track formed by a pair of longitudinally extending track members providing a pair of transversely spaced supporting surfaces and a pair of transversely spaced guide surfaces; and a trolley having a body on which supporting wheels and guide rollers are rotatably mounted. The trolley body includes a shield member that is disposed adjacent to the guide rollers, extends radially outwardly of the periphery thereof, and overlaps the guide track surfaces engaged thereby. A socket, formed in the trolley body and having one end closed by the shield member, movably supports a driving dog which has a stem portion projecting into the socket and engaged therein by rollers and wear plates carried by the trolley body. The shield member is located above the trolley and forms a cover that protects the moving parts of the trolley from contamination and decreases the possibility of a foreign object becoming wedged between the guide rollers and guide track surfaces.
