saidpsill seats formin extensions of the upper flange l of the bolster and being in substantially the plane thereof.

lxtendixngr obliquely outwardly from the members ti are armsl il, shown in dotted lines in said Fig. L. and these arms` t) are likewise provided with sill seats T, which are praccontintmtionsl of the said upper tically flange l.

Arranged vin the arc of a circle struck from the center bearing are side bearings l0 'which serre as connectors for the obliquely disposed arms il, v aid sido laairingsnbein provided with bottom tlanges llnltl-e'xe' tend to a plane lsomewhat below the bottom flange 5 ol' thev bolster trurtnre for well understoml purposes.

The sill seats i' are provided with reinforeinf?r ribs la which intersect the arms 9 extending under l aid `sill seats and with lian res Tb which extend at subs-tantndlr-right angles from the armsl t3 before referred to.
