Railway car superstructure frame
First Claim
1. A welded structural frame for a railway car wall which displays low distortion during and after assembly comprising:
- a longitudinal U-section member forming part of a side wall frame and having a pair of opposed, horizontal sides and having a vertical base interconnecting said horizontal sides, said U-section member also having an outer surface disposed in a generally vertical plane to facilitate attachment of an outer wall sheath;
a pair of aligned, wall pillar members fitted about the U-shaped member with one abutting each of the sides of the longitudinal member and being welded thereto and said pillar members having an outside, flat section in alignment with and in a vertical plane with the outer surface of the longitudinal U-section member thereby providing a smooth, continuous surface for attachment of an outer wall sheath to said railway car;
a reinforcing member having means located at the juncture of the wall pillar members and the longitudinal U-section member therein and having weld means to interconnect the reinforcing member and the sides of the longitudinal member forming means in alignment with the vertical pillar members to thereby provide a continuous, structural wall pillar member extending through the longitudinal member for improved rigidity and dimensional stability.

Abstract
A welded structural frame for a railway car wall is disclosed as including a pair of aligned U-section vertical members welded to opposite sides of a U-section longitudinal member and a reinforcing insert welded between the sides of the longitudinal member in alignment with the vertical members to provide a frame substantially free of welding distortion. A method of making such a frame is also disclosed as including securing longitudinal and vertical members in a fixture, welding the vertical members to opposite sides of the longitudinal member and then welding a reinforcing insert between the sides of the longitudinal member in alignment with the vertical members.

9. A method of constructing a low distortion welded structural frame for a railway car wall comprising:
-
a first step of welding a pair of aligned wall pillar members to opposite sides of a U-shaped longitudinal member having a pair of horizontal sides interconnected by a base and aligning the outer portions of the wall pillar members and the longitudinal member in a common plane to facilitate attachment of an outer wall sheath for said railway car; a second step of positioning a reinforcing member between the sides of the longitudinal member in alignment with the wall pillar members; and a third step of welding the reinforcing member to the sides of the longitudinal member in position to provide a continuous framing member extending across said railway car. - View Dependent Claims (10, 11)
