Abstract: In a railway hopper car with several bottom dump doors, the doors are operated by a main door operating member in the form of a thrust bar running the length of the car. The bar, when moved, rotates levers which rotate actuator shafts which move door operating linkage arrangements, opening and closing the dump doors. An adjustable positioning structure is provided on each lever to cause adjustment of the individual dump door positions. The adjustment is accomplished by tightening or loosening bolts in the adjustor, which is fixed on an actuator shaft running to the linkage arrangement. The adjustor and actuator shaft rotate on a bearing with respect to the lever, but are held in locked adjusted position by the adjustor bolts abutting on flanges welded to the lever.

Abstract: A side sill and side wall joint arrangement for a railway box car wherein channel shaped side sills are provided having inwardly offset upper vertical webs such that the side sheets of the car may be secured to them to provide a flat outer surface between the respective sheets and the lower portions of the sills against which straight side posts may be secured.

Abstract: A load distributing and vibration damping center bearing assembly for a railway car including a body center plate assembly including a base plate secured to the body bolster, a flat truck bowl bearing plate, and an elastomeric disc sandwiched therebetween and bonded between the brass plate and bearing plate to abate and dissipate destructive radial and vertical impact loading on the truck bowl and center plate during rail operations.

Abstract: The present invention relates to a load equalizing and vibration damping center bearing assembly for a railway vehicle. The center bearing assembly includes a flat body center plate depending from the car body, a bowl having a downwardly concave curved inner surface supported on the wheel truck, a tiltable insert disposed in the bowl having a flat upper surface mating with the body center plate and a curved lower surface contiguous to the inner surface of the bowl, and a resilient liner interposed between the insert and the bowl which absorbs vehicle vibration and assures constant and uniform bearing support through said bearing assembly between the vehicle body and the associated wheel truck.
