One of the illustrations which should devolve upon the truck consistent with the load car- shows the heart shaped rocker in detail. The swing bolster ried at the centerpin has been, to a considerable extent, taken bears directly on these rockers which are connected to it by up by the leading drivers, resulting in lack of stability on tan- links to insure their remaining in the proper position. f Spring Ooard om/ffedwhen bmke is i/sed
