ABSTRACT:
A connection is described for securing the ends of a transom to rocker seats which are each supported on a pair of rocker seat bearings that are designed to rest in u-shaped channels which are formed in the sideframes of a railroad car truck or bogie. The aligned holes in the overlapped transom ends and rocker seats are provided with oppositely tapered conical seats to matingly receive a conically shaped end of a nut which threadably engages the shaft of a bolt which has a conically shaped head which matingly fits in the conically tapered seat of the hole opposite the nut. A metal lock nut or an elastomeric locking ring can be provided to engage the nut and bolt to prevent them from loosening and eventually coming apart.
