Definitions

  • a vertical spacer plate for withstanding the shear and vertical forces service imposed thereat.
  • a separate tie plate horizontally spanning the sill pocket exterior of the center plate and connected to the underedge of each spacer plate provides stiffening reinforcement.
  • SHEET 3 [1F 3 INVENTOR STANLEY H. FILLION COMBINED BODY BOLSTER CENTER FILLER AND CENTER PLATE FOR RAILWAY CARS BACKGROUND OF THE INVENTION 1.
  • the field of art to which the invention pertains includes the art of railway rolling stock and more specifically to a freight car body underframe for mounting onto the bolster of a supporting truck.
  • the invention relates to an improved body bolster center filler-center plate combination for railway freight cars. More specifically, the invention relates to such an improved com bination for use with freight cars as to afford substantially greater structural capacity more readily able to accommodate higher in-service load forces imposed by the larger and heavier car loadings.
  • the consequent result of the design of the invention is to decrease previous failures and afford a life expectancy to the center plate more nearly approaching and even equal to optimum life expectancy of the car itself.
  • the design hereof capable of accommodating the current trend toward heavier car loading but it achieves the result without resorting to obvious approaches of increased mass or more expensive materials and/or foundry practices.
  • the instant design achieves greater load carrying capacity by a material reduction and at substantially less cost than would have been reasonably expected when compared to similar purpose structures of the prior art.
  • FIG. 1 is an elevation of a bolster construction containing the invention hereof in a first embodiment shown assembled on a supporting truck bolster;
  • FIG. 2 is a partial underside plan view of the center plate mounted onto the center sill of the car body;
  • FIG. 3 is a sectional elevation takenin-the bolster direction substantially along the lines 3-3 of FIG. 2;
  • FIG. 4 is a sectional elevation taken substantially along the car center line 44 of FIG. 2;
  • FIG. 5 is a topside plan view, partially in section of the center plate
  • FIG. 6 is an elevation in partial section taken substantially along lines 66 of FIG. 5;
  • FIG. 7 is an elevation in partial section taken substantially along the lines 77 of FIG. 5; p
  • FIG. 8 is a topside sectional plan view of a second invention embodiment in accordance herewith for accommodating draft lugs
  • FIG. 9 is a sectional elevation taken substantially along the car center line 9-9 of FIG. 8;
  • FIG. 10 is a sectional elevation taken in the bolster direction substantially along the lines 10-10 of FIG. 8;
  • FIG. 11 is a sectional elevation taken substantially along the bolster center line 1 1-11 of FIG. 8.
  • FIG. 1 a body bolster 9 having side bearing supports 16 and 17 extends transversely to a car body intersecting the body center sill 10 thereon.
  • Bolster 9 contains center plate 15 and is normally connected via an interfit with bowl 13 to a truck bolster l1.
  • Avertical king pin 12 extending upward from bowl 13 through a bore 14 in center plate 15 provides a safety measure against separation in the event of any vertical displacement in service.
  • Such a connection is conventional in the industry and will not be further described. Mention herein to top, bottom, underside, topside, horizontal,” vertical,” etc. will be with regard to the orientation shown and described in connection with FIG. 1.
  • center sill 10 is conventionally comprised internally in cross-section as an inverted U shaped steel-rolled section consisting of vertical side walls 22 and 23 joined by top wall 24 to define a centrally interior longitudinally extending hollow pocket 25 therein.
  • At the underside for increasing strength of the section are apair of parallel longitudinally extending flanges 20 and 21 laterally integral with side walls 22 and 23.
  • central pocket 30 formed open and exposed at the bottom by parallel spaced apart vertically arranged spacer plates 31 and 32 and the included portions of sill walls 22 and 23 therebetween.
  • Each spacer plate is complementary to the internal sill cross-section thereat and is completely welded about its periphery in a rigid fixed relation to the intersecting surfaces of side wall 22 and 23 and top wall 24. Further securing the spacer plates in the latter relation, for reasons as will be explained below, are horizontal tie plates 33 and 34 each extending laterally across pocket 25 adjacently outward of pocket 30.
  • the tie plates are arranged with their undersurface between and substantially co-planar with the undersurface of side flanges 20 and 21 and are secured welded on three sides to the contiguous surfaces of sill walls and spacer plate thereat. By this means a completely rigid joint is formed at the intersection of the tie plate to the lower end of the spacer plate.
  • Center plate 15 hereof generally comprising a bowllike configuration is most clearly shown in FIGS. -7.
  • the center plate comprises a lower cap section 35 of generally circular extent and of a diameter greater than the internal clearance dimensions of pocket 30.
  • Communicating integral with the cap is an upper webbed section 36 of dimension able to be received within pocket 30.
  • Centrally located in cap 35 is a recess 39 communicating with bore 14 formed in an upstanding hub 40 and through which a truck bolster king or center pin 12 is received as described above in connection with FIG. 1.
  • Bevel flats 37, at the under opposite corner edges of cap 35, provide line instead of point contact against truck bowl 13 during dynamic in-service oscillation therebetween.
  • cap section 35 is represented by four corner positioning pads 41 each having a finished horizontally extending surface and connecting with intermediate bevelled welding surfaces 42.
  • Upper section 36 includes a thin encircling web 44 which extends integrally upward from the plane of pads 41 and slopes approximately 3 inward to permit easy insertion within fill pocket Providing additional reinforcement to central hub 40, are a plurality of web flanges 43 extending radially to merging with each of the enclosing side walls of web 44. Center plate in its entirety is preformed of cast steel or the like without the necessity of hot pressing and by virtue of its size can be easily handled for purposes of finish machining and/or heat treatment if desired.
  • Assembly of the center plate into pocket 30 is by first placing positioning pads 41 against the exposed surface edges of sill and spacer plates and then butt welding around at 45 between surface 42 and adjacent sill or spacer edges thereat.
  • the side welds act in forming a secured and completely boxed structure with center plate 15 closing off the pocket bottom.
  • spacer plates 31 and 32 welded on three sides to the sill walls thereat become welded on their fourth side to center plate 15.
  • the upright spacer plates are ideally secured for resistance against parallelogramming of the sill during rock and roll of the moving car.
  • the spacer plates act as a virtually perfect bolster shear transfer device while also serving as vertical load support. Should the center plate require maintenance by virtue of either failure or wear it can similarly be removed without disturbing the balance of the structure.
  • FIGS. 8-11 there is shown a second embodiment in accordance herewith modified to accommodate draft lugs as when the center pin to face of rear draft lug distance is on the order of less than about 27-30 inches.
  • This embodiment therefore includes the same center plate 15 assembled into pocket 30 in a similar manner as above and is otherwise modified only to accommodate a pair of draft lugs designated 53 and 54.
  • Each lug comprises a relatively wedge-shaped composite perforated casting of numerous slots 58 and extending in a direction of the center line of car from the larger lug face end 55 to its opposite terminal end 56 located just beyond the bolster center line.
  • Spacer plate 31 is coped at 57 to fit the lugs for welding therebetween.
  • each lug is welded top, side and along the periphery of slots 58 to sill top wall 24, and side walls 22 or 23 thereat.
  • center filler and center plate for freight cars having increased capacity to withstand greater carloads without failure than heretofore.
  • the center plate is initially produced as a separate component affording greater versatility with respect to the latter as for heat treating, machining, or the like if desired.
  • the center plate can be readily removed for maintenance without the expensive down time as has been associated with integral center plate-center fillers of the prior art.
  • construction hereof relatively simple as compared to prior art devices despite its relatively increased load carrying capacity, but by virtue of such simplicity, materials and labor for fabrication is significantly reduced resulting in substantial cost savings of manufacture.
  • the invention has been principally described in connection with freight cars, it obviously could be employed if desired in passenger cars or the like.
  • a body bolster center filler-center plate assembly for a railway car comprising in combination:
  • a center sill having walls contiguously arranged generally U-shaped in cross-section and forming a centrally open interior
  • a body bolster of longitudinal extent having a centrally defined laterally extending opening receiving said center sill intersecting therewith;
  • spacer plates longitudinally spaced apart secured within said sill interior to the walls thereof, at least one of said plates being located on each side of the center of intersection between said bolster and sill;
  • said spacer plates and portion of sill side walls included therebetween defining a generally rectangular bottomopen pocket in which to receive a center plate;
  • a center plate having a first portion of exterior dimension greater than said pocket for extending outward of the underside thereof and connecting with a second portion of reduced exterior dimension received within said pocket; and means securing said center plate to the underedge of said pocket walls forming a fixed rigid structure thereat, said center plate being detachable upon removal of said means.
  • a center filler-center plate assembly as in claim 1 including horizontal tie plates adjacently exterior of said defined pocket secured to the sill side wall and spacer plate thereat.
  • a center filler-center plate assembly as in claim 3 in which said pocket is generally square and said center plate is secured welded to the underedges of said pocket walls.
  • a center filler-center plate assembly as in claim 4 in which said center plate includes a centrally hollow upstanding hub to receive a king pin from a truck bolster on which it is to be supported.
  • a center filler-center plate assembly as in claim 1 including draft lug means secured interior of said sill in the vicinity of said pocket and extending in a direction generally parallel to the center line of said sill.
  • a center filler-center plate assembly as in claim 7 in which at least one spacer plate is coped for a draft lug to extend into said pocket.
  • a center filler-center plate assembly as in claim 10 in which the fixed connection between said draft lugs, said one spacer plate and said sill transmit draft forces imposed against said lugs divided between the top and side walls of said sill.
