This malleable casting also confines the bearing inthe pedestal by the of the under helical spring againstthe bottom of the axle box ( Fig. 5). The loads often being verysevere at the ends of the truck, especially on a poor or uneven roadbed, they are not only supported below, but are as well suspendedfrom above. The cross stay or center bracing of each diamond, is done by part of the side frame end casting, thus completeh checking the os-cillation. The axle box is of an improved pattern, especialh- adapted to
