  • Patent number: 4875417
    Abstract: An end structure for a railway car, and more particularly a covered hopper railway car, is disclosed which has side sill extensions extending diagonally inwardly from the ends of the side sills to the center stub sill for transmitting substantially all of the longitudinal, horizontal loads between the center stub sill and the side sills. A generally vertically extending truss is provided between the center stub sill and the end of the car above the center stub sill so as to withstand overturning moments and vertical loads between the end of the car and the center stub sill. A connector casting rigidly interconnects the side sills and the side sill extensions. A transition plate is in face-to-face engagement with the side sheets at the outer ends of the side sills so as to facilitate the transfer of load between the side sills and the side sheets. A cutout is provided in the bottom of the side sills at the ends thereof so as to enable interior welds to be made.

  • Patent number: 4646653
    Abstract: In a stub sill open top railroad car, such as a gondola or hopper car particularly adapted for coal service, a corner fitting or casting is provided at each end of the car joining the top chord extending along each side of the car with the end chord, the latter extending transversely of the car at the upper ends thereof. The corner casting includes projections which extend into the top and end chords so as to facilitate making an integral (i.e., welded) connection between the chords and an adjacent end diagonal member. In one embodiment, the casting includes a downwardly extending portion which is received within and to which the diagonal is welded, while in another embodiment, a connection plate is utilized to secure the end diagonals to the corner casting.
