ABSTRACT:
A fabricated center filler and center plate construction for the underframe of a railway car in the area where the body bolster intersects the center sill. The fabricated center filler includes four interconnected, vertical walls and a bottom floor plate secured by welding thereto. The center filler is secured by welding to the vertical sidewalls of the center sill with the floor plate of the center filler positioned flush with the lower surfaces of the center sill flanges. Opposed ends of the center filler floor plate preferably are overlapped by portions of the bottom cover plate of the bolster and are secured by welding hereto. A king pin receiving tube is secured by welding within a hole formed in the floor plate of the center filler, the tube having its upper end positioned within the confines of the center filler and having its lower end positioned below the floor plate. Bracing means, preferably in the form of plate members, are angularly disposed within the center filler and secured by welding to the upper end of the king pin tube and to the walls of the center filler. The disclosed combination further includes a center plate having an outwardly extending bowl portion with a central hole formed therethrough to receive the lower end of the king pin tube therewithin to provide a mechanical interlock between the center filler and center plate. The upper surface of the center plate, surrounding the king pin tube, bears against the floor plate of the center filler while opposed upper edge portions of the outer periphery of the center plate bear against the flanges of the center sill and against the floor plate of the center filler, respectively. The center plate is secured to the center filler floor and king pin tube and also to the center sill flanges preferably by way of exposed weld beads which permit torch removal of the welds whereby a damaged or worn center plate may be replaced without removing the center filler from the center sill.
