发明名称 Combined center plate/center filler for railway freight cars
摘要 A combined center plate/center filler construction for the underframe of a railway car is provided with sloped, corner circumferential sections at the upper portion of the center plate to allow for the complete welding of the center plate to the undersurfaces of a pocket-receptacle of the underframe, so that one continuous welding operation may be performed. The upper portion of the center plate has four corner positioning projections the upper horizontal surfaces of which are coplanar with the horizontal plane containing the joinder of the center plate to the center filler.
