<p>In a railway car truck, friction shoes are carried in pockets at opposite ends of the bolster. The invention provides for easy insertion of the shoes into the pockets, and retention therein by retaining lugs on the bolster which are received and retained in cooperating indentations of the friction shoes so that assembly may be easily accomplished. The shoes are prevented from dropping in the event their control springs become damaged or broken.</p> |
