Definitions

  • a body bolster is normally used at each end of a railway tank car to distribute the load from the wear plates to the shell.
  • the wear plates are, of course, supported immediately from the wheel trucks of the tank car.
  • the body bolsters also serve as jacking members when it is necessary to raise the tank body off the wheel trucks.
  • An object of the present invention is to provide a new and improved body bolster construction.
  • Another object is to provide a body bolster construction having a superior load transition characteristic for transferring loads from the wheel truck to the tank body.
  • a body bolster construction basically fabricated from a single web thickness and tubular compression members in the form of pipe closures.
  • the combination provides a lightweight, non-bulky, inexpensive body bolster which, nevertheless, affords load transition characteristics from truck to tank body, comparable with cast transition members and double web bolsters now in common use in the railroad industry.
  • FIGURE 1 is an elevational view of the bolster construction embodying features of the present invention, showing its relation to a tank body and a railway car truck; both only partially shown;
  • FIGURE 2 is a sectional view taken along line 2-2 of FIGURE 1;
  • FIGURE 3 is an elevational view of one-half of a bolster construction embodying a modified form of the invention.
  • FIGURE 4 is a sectional view taken along line 4-4 of FIGURE 1.
  • the tank car 10 includes a tank body 11 supported from a pair of conventional wheel trucks 12 (only one shown) by corresponding identical body bolsters (only one shown) embodying features of the present invention.
  • the tank body 11 itself comprises a tank shell 20 which is substantially cylindrical and constructed in a conventional manner of steel plate.
  • the shell 20 is centered over and seats snugly between opposed sections 25 of a body bolster 15 on each end of the tank car 10.
  • Each of the body bolsters 15 is identical in construction.
  • each section 25 of each body bolster 15 is identical in construction. Accordingly, only one body bolster section 25 is described in detail and corresponding reference numerals are applied to corresponding components of each.
  • Each body bolster section 25 includes a bolster saddle plate 30 contoured to the radius of curvature of the tank shell 20.
  • bolster saddle plate 30 is preferably onehalf inch steel plate and is approximately eighteen inches wide. The plate 30 extends from a lower end 31 adjacent the vertical center line CL of the tank shell 20, upwardly along the side of the shell to an upper end 32 immediately below the widest portion of the shell.
  • a bottom plate 35 Extending along the bottom of the tank shell 20, and also contoured to its radius, is a bottom plate 35.
  • the bottom plate 35 is welded to the bottom of the shell 20 along its axis and also to the lower ends 31 of each of the bolster saddle plates 30 bracketing it, as illustrated.
  • a heavy steel channel member 40 Depending from the bottom plate 35 is a heavy steel channel member 40.
  • the channel member 40 supports the bottom plate 35 on its arcuate base 41, which is welded to the bottom plate by fillet welds 42.
  • the depending legs 43 of the channel members 40 have outwardly extending anges 44 formed at their lower ends.
  • the anges 44 define the lower-inner extremity of each bolster section 25.
  • each bolster pipe 50 Extending downwardly from adjacent the upper end 32 of each bolster plate 30, and inclined slightly outwardly, is a bolster pipe 50.
  • Each bolster pipe 50 is a conventional steel pipe welded to the outer surface of the bolster plate 30 at a corresponding -upper end, as at 51. In this light, the upper end 52 of the pipe 50 lends itself readily to being contoured for another advantage of the invention.
  • Each pipe 50 extends downwardly from the bolster plate 30 to a bolster base plate 55 which spans the distance between the corresponding ange 44 on the center channel 40 and the lower end of the pipe 50.
  • the pipes 50 are here six inches in diameter, but this may vary with the size of the tank car 10.
  • Each bolster base plate 55 is connected to the ange 44 by a welded plate 56, welded to the lower surface of each, as illustrated in FIGURE 1.
  • a welded plate 56 welded to the lower surface of each, as illustrated in FIGURE 1.
  • At the outer end of the plate 55 its upper surface supports and is Welded to the lower end of the pipe 50, as at 57.
  • the area between the corresponding leg 43 of the channel member 40, the bolster pipe 50, and the arcuate bolster saddle 30, as well as the mounting angle bolster plate 55 in each bolster section is occupied by a single thickness steel plate web 60.
  • the web l60 which is in the present illustration (but might vary in thickness with tank car 10 size) one-half inch thick, is welded to the corresponding channel leg 43, saddle plate 30, pipe 50, and plate 55, along its edges.
  • a fillet plate 61 is welded to the outer surface of the lower end of each bolster pipe 50 and to the underhanging upper surface of the plate 55 to enhance the integrity of each bolster section 25. Only single fillet plates 61 are shown, but two spaced plates 61 are frequently used.
  • each of the mounting angle base plates 55 is an angle iron wear plate 66.
  • the wear plates 66 might be solid blocks or layered plates, for example.
  • the wear plates 66 are conventionally spaced slightly from bearing plates 67 on the wheel truck 12.
  • each bolster section 25 Positioned over the wear plates 66 and bracketing the web 60 in each bolster section 25 is a pair of identical web stiffener plates 70 of One-half inch steel (though they also might vary in thickness) welded along one side 71 to the web 60, along their lower edges 72 to the mounting angle plate 55, and along their upper edges 73 to the arcuate bolster plate 30.
  • the sitesner plates 70 stiffen the bolster sections 25 in that area where the greatest stresses are developed; in other words in the load transfer area.
  • stiffener plates 70 are employed in the form of the invention illustrated in FIGURES 1 and 2, and described above, the invention also contemplates using pipe stiffeners, such as in the bolster section embodiment illustrated at 115 in FIGURE 3.
  • stiffening of the web 60 is accomplished by sectioning it and inserting a short segment of pipe 170 in the web.
  • the opposite sides 171 of the pipe segment 170 are welded to corresponding edges of the sectioned web 60, the lower edge 172 to the angle member 55, and the upper edge 173 to the bolster member 30 (see FIGURE 4).
  • a bolster construction for supporting the weight of a tank body from a wheel truck in a railway tank car comprising:
  • tubular compression members serving as primary load transition means and said web means serving to spread the load between said base means and said saddle means.
  • said web means comprises generally flat plate means welded to said saddle means, said base means, and said tubular compression members.
  • each of said tubular compression members comprises a circular cylindrical pipe having its upper end cut on a bias in the shape of and welded to said arcuate saddle means.
  • said plate web means is stiffened vertically by web stiffener means secured to and extending transversely of said plate web means.
  • a bolster construction for supporting the weight of a tank body from a wheel truck in a railway tank car comprising:
  • tubular compression members serving as primary load transistion means and said web means serving to spread the load between said base means and said saddle means.
  • each of said tubular compression member means comprises a circular cylindrical pipe having its upper end cut on a bias in the shape of and welded to said arcuate saddle means.
  • said web stitfeners each comprise a pair of plates edge-welded to said plate web means in perpendicular relationship thereto.
  • said web stiffeners each comprise a pipe member extending transversely through said web plate means and welded thereto.
  • said plate web means comprise a pair of web plates lying substantially in the same plane and spaced laterally of the body by a longitudinally extending structural member
