Means for supporting third rail collector gear and the like on inside bearing railway trucks

摘要

For supporting equipment such as third rail collection gear, which must be maintained at constant height above the rails, on inside bearing trucks in which the truck frame is spring-supported from journal boxes vertically movable relative to box section truck frame side members, equipment support beams extend longitudinally of the truck within the respective frame side members and are pivotally supported at their ends from the respective journal boxes. Intermediate the axles, the truck frame side member outer walls are formed with apertures and equipment mounting plate structures are positioned outwardly of the respective truck frame side member outer wall and are secured rigidly to the equipment support beams by longitudinally spaced securing bolts passing through the apertures in the truck frame side member outer walls, and for stabilizing the mounting structure against tipping transversely of the truck, vertically and longitudinally spaced vertical bearing surfaces are formed on the outer wall of the truck frame side members and the mounting structures are held in vertical sliding engagement with these surfaces by the bolts securing the mounting structures to the equipment support beam, and the equipment exemplified by third rail collection gear is fixedly mounted on the plate structure.
