Definitions

  • the invention relates to welded underframes for railway cars and consists in so arranging the corner plates and gusset plates, that a particularly favorable transmission of the forces at the points of junction and. a low expenditure ofma'terial is obtained.
  • Figure 1 is a top view, partly in section, of the underframe
  • Figure 2 is the corresponding side view, partly in section on line 2-2 of Figure 1,
  • Figure 3 is a section on line 3-3 of Figure 1, seen fromthe right, while (Z and (P.
  • the gusset plates d are located in the plane of the upper flanges of the sills B and struts D, while their connection with the side sills A is established at the web side of the latter.
  • the plates (Z are located in the plane of the lower flange of the struts D and are welded with this flange and the webs of the sills A and B.
  • the buffer struts I are cut away obliquely and are welded there with the web sides of the intermediate sills C.
  • cross bars E are provided transversely of the sills A and U, and underlie the intermediate sills O.
  • the cross bars E abut with their blunt ends on the web side of the sills A and are welded with them both immediately and through the medium of corner plates 6 arranged in the plane vof their flanges.
  • the connection of the bars E with the intermediate sills C is established
  • Figures 4: and 5 show in enlarged scale 75 sections on line 1-4 and 5-5, respectively, immediately by welding at the crossings and of Fi ure 1, by gusset plates e located in the plane of ed with the flanges.
  • A denote the two side sills of the underframe, which are interconnected by end sills B.
  • the upper flanges of the ,side sills A are cut away at their ends a distance equal to the width ofthe upper flanges of the end sills B.
  • connection between theuppe'r flanges of the sills A and B is established by corner plates a located in the plane .of these flanges and having the same thickness as the latter, these corner plates (1 being butt-weld-
