Abstract:

Improvements in cast metal sideframes for railway trucks are disclosed, along with improvements in the processes of casting such products and the cores used in the casting process. A radial draft is provided on the casting surrounding a bolt hole at a core parting or joint line so that nuts and washers may be evenly loaded. The radial draft is formed on the sideframe column, on the side opposite the side to which a wear plate is mounted. The bolts for mounting the wear plate extend through the bolt hole, and the nuts and washers connected to the bolts bear against the tapered radial draft surface.
