Definitions

  • the simplification of the structure brings about also the achievement of ancillary objects, if not primary objects, of the invention, namely decreased weight, increased strength, and greater facility of manufacture resulting in increased economies both by reason of fewer parts entering into the structure, fewer joining operations, greater accessibility to the parts for joining them, and duality of function of certain of the parts whereby they serve several functions heretofore performed only by separate parts.
  • This lower rail inv large part of Ithrough running members extending throughout the length of the car body.
  • An important feature toward the attainment of these objects consists in the provision, as an element of the bottom rail structure, of a plate girder structure. having as a main element thereof a vertically deep through running plate secured directly to the inner faces of the posts and diagonals entering into the truss structure.
  • This plate gir'der not only adds very materially to the strength of the 36 bottom rail structure but, being located as it is adjacent the floor level and extending thereabove an appreciable distance, it serves also to form a substantial part of the walls of the heater duct extending lengthwise of the car body in this 40 location.
  • a through running member uniting with the through running vertical plate girder already referred to may constitute an outer inwardly facing flanged channel scuff rail applied to the outer faces of the posts and secured thereto opposite the lower portion of the plate girder.
  • Figure 1 shows more or less diagrammatically and in side elevation a rail car sidewall truss structure in which the invention is embodied.
  • Figure 2 is an enlarged detail perspective view of a portion of the structure, said view being taken substantially along the line 2-2 of Figure 1 looking in the direction of the arrows, certain 20 of the parts' being broken away to more clearly show the structure, and floor beams being'indicated. y
  • Figures 3, 4, 5 and 6 are detail transverse sectional views on an enlarged scale taken substan- 25 tially along the line 3 3 of Figure 1 looking in the direction of the arrows and showing the successive steps in the assembly of the bottom rail structure.
  • the side wall truss structure embodying the 30 invention may consist of the vertical posts Il), the top rail member II, a bottom rail member I 2, and the belt rail I3. Additional posts I4 may be provided in the regions of the window openings extending only to the belt r'ail. AThe diagonals I5 35.
  • This plate girder structure is 50 secured to the inside faces of the posts and diagonals, the posts I0 extending therebelow some distance, these extended ends of the posts, see Figure 2, being adapted to receive thereagainst for secur'ement thereto, transverse floor beams as 55 I8.
  • the vertically deep plate girder extends from the top of the floor beams upwardly a .distance suficlent to form the inner Wall of the heater duct usually provided in this location but entirely separate from the framework of the structure.
  • the vertical plate girder I'I has the dual function of forming the inner wall face of the heater duct and at the same time providing a main structural member of the side frame, thereby simplifying the structure as a whole.
  • the plate girder may be subassembled to include in the subassembly the vertical plate I9, a top through running angular member 20 spot welded to the upper margin of the plate I9 and having its inwardly extending arm form a portion of the top of the heater duct and serve as'securing means for the inner wall portion of the heater duct, and a bottom inwardly facing channel 2
  • the plate girder I1 may be said to consist of a top chord 20i a bottom chord 2
  • are readily assembled in subassembly and applied as a subassembly as shown in Figure 3 to the inner faces of the posts I9 and secured thereto by spot welding the portions overlapping the posts to the inner walls of the posts.
  • the post is of a flanged channel section facing outwardly as shown
  • the securement of the plate girder subassembly I'I is to the bottom wall of the channel. This arrangement renders the joint readily accessible for spot welding.
  • the gussets I6 connecting the posts and bottom rail are preferably applied to the posts after the plate girder subassembly I'I has been applied and secured in place.
  • the gussets I 6 are readily secured to the posts by spot welding them to laterally extending flanges Illa, Ib forming the outer faces of the posts as shown in Figures 2 and 4.
  • the outer portion of the bottom rail structure comprises a through running scuff rail 23 of inwardly facing flanged channel section, this scui rail being arranged substantially at the floor level and having its flanges spot welded to the laterally extending post flanges as well as to the gussets I6.
  • This scuff rail may be Welded to the gussets and the subassembly so produced then applied to the posts and spot welded to the posts. However, this is not essential, and it may be more convenient for the manufacturer to assemble the gussets to the posts first and thereafter assemble the scuff rail 23 to the combined posts and gussets.
  • the vertical plate I9 and the top flange 24 of the scuft rail 23 are interconnected by a bridging member extending between adjacent posts.
  • This bridging member in the preferred form shown comprises a downwardly facing channel, the outer side wall of which overlaps and is spot welded to the top flange 24 of the scuff rail 23 and the inner side wall overlaps and is spot welded to the vertical girder plate I9.
  • the application of these bridging members between the posts constitutes the third stage in the assembly of the bottom rail structure, as shown in Figure 5, the downwardly opening channels 25 being readily attached tothe adjacent parts by entering the welding tools through the open bottom of the structure.
  • the outer side Wall of the channels 25 is preferably arranged in the plane 0f the gussets and is offset inwardly, as indicated at 26, through its region of overlap with the gussets to which it is also spot welded in this region.
  • bottom rail construction it is finally closed as shown in Figures 2 and 6 to box-section form by a bridging member 27 joining the bottom flange 28 of the seuil? rail 23 and the bottom inwardly extending flange 29 of the channel floor Stringer 2
  • the bridging mem ⁇ bers 2'! extend between the posts and are preferably of angle form, one arm of the angle overlapping and being directly spot welded to the bottom flange 28 of the scuff rail and to the gussets in the region of overlap therewith.
  • This arm 30 is also offset inwardly in the region of the gussets in the same manner as the outer Side wall of the channel 25.
  • the other arm of the bridging angle 2'I is extended inwardly to overlap the bottom side 29 of the channel 2
  • the bottom rail structure is further strengthened and stiffened and a strong anchorage is provided for the diagonals 22 by the mutual interconnection of these parts to each other and to the posts.
  • the diagonals in the present instance are shown consisting of two channel members spot welded back to back, these channel members having their outer walls in the outer plane of the posts and their inner walls in the inner plane and the outer walls overlapping the gusset members I6 and being spot welded thereto while the inner walls overlap the vertical plate I9 and are spot welded thereto.
  • the parts entering into the improved bottom rail construction can be readily formed by draw rolling or otherwise and can be most economically manufactured and joined together in the flnal assembly by the usual spot welding equipment.
  • they provide a very strong bottom rail construction and one that forms a strong joint between the posts and diagonals of the side wall truss construction and further enters into the structure of the usual heater duct. All of these advantages are obtained with a minimum of weight in the structure.
