The forward ends of the Webs lnre united by e trnnsversely disposed web or nieto 25, which, when the device is properly applied. for use, engages directly against the rear side of the end sill 12, end formed -intee'rsl with the forwerd ends of the draft arms is 's transversely disposed late A27 which engages directly egsinstt e front fece of the end sill.` yThe ends of this plate 2T ere reinforced by boes- 28, the same being; perforated inorder to receive the ends of truss rods 29 which extend in the usuel inf-nner from one end sill to the other.

The construction just described not only provides very ,substantiel washers for the of the tram rods end prevents the nuts from pulling intoA the end sill, but also the entire cor together from end to 'end ugh the draft arms end sill reinforcesnd seid truss rods.

Where my improved device is used 1n connection 'with wooden curs and truss rods the ends of the lutter are anchored'or connected directly to the ends of the dead block, thereby eiiectively distributing all pulling strains and tyin# the entire cnr underfrzune from end ,to en The transversely disposedplntes 26 und 27 at the forward end of the device engage the front und rear sides of the end sill, thereby providing n stronzor and substantiel connection between the underframe end end sill, which will be eilective in reducing demnge done by shifting loods, which, under ordinary conditions, frequently teer out the end sill -sfndf'end of the cnr.
