Abstract
For supporting equipment which must be maintained at constant height above the rails, such as third rail collection gear, on inside bearing trucks in which the truck frame is spring-supported from journal boxes vertically movably mounted in downwardly open pedestal jaws in the truck frame side members, an equipment support beam extends longitudinally of the truck below the frame side members and the beam or pedestal legs are bifurcated at their ends to clear each other and the pedestal tie bars and the beam end portions are suspended from the bottoms of the respective journal boxes at each side of the truck, such that the equipment support beam is constantly maintained at a fixed distance above the rail whereby to maintain the supported equipment, including the third rail shoes, at a constant level with respect to the third rail. To accommodate differential tilting movements of the axles transversely of the truck and differential vertical movements of the axle boxes at the respective sides of the truck, the ends of the beams are supported on longitudinally extending pivotal axes from the respective journal boxes and the pivots are provided with elastomeric bushings.
