<p>FRICTION CASTING BOLSTER POCKET WEAR PLATE HAVING A PLURALITY OF SIDES A railroad car truck bolster has a plurality of pockets each of which will position a friction wedge for use in damping motion between the bolster and the side frame. Each pocket has a slanted rear wall and adjoining side walls perpendicular thereto, the side walls being generally perpendicular to the longitudinal axis of the bolster. One of the side walls is designated the inboard side wall and the other is designated the outboard side wall. The present invention is specifically concerned with a wear plate which is positioned within the friction wedge pocket and has a main portion formed and adapted to substantially conform to the pocket slanted wall and at least one wall portion integral therewith and formed and adapted to substantially conform to the pocket outboard side wall, an area subject to substantially greater wear than the inboard pocket side wall. Further, there are means on the wear plate for cooperative attachment of the wear plate to the pocket.</p> |
