CONVEYOR TROLLEY AND TRACK ABSTRACT A conveyor trolley and track comprising a track formed by a pair of longitudinally extending track mem- bers (13, 14; 13A, 14A) providing a pair of transversely spaced supporting surfaces (15, 16) and a pair of trans- versely spaced guide surfaces (17, 18); and a trolley (10; 10A) having a body (20) on which supporting wheels (21, 22) and guide rollers (25, 26) are rotatably mount- ed. The trolley body includes a shield member (30; 30A) that is disposed adjacent to the guide rollers (25, 26), extends radially outwardly of the periphery thereof, and overlaps the guide track surfaces (17, 18) engaged there- by. A socket (44) formed in the trolley body (20) and having one end (50) closed by the shield member (30), movably supports a driving dog (54) which has a stem por- tion (58) projecting into the socket and engaged therein by rollers (63, 64) and wear plates (68, 69) carried by the trolley body (20). The shield member (30; 30A) 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 sur- faces.
