R'IHHMI \N INVENTOR fimzzZo 4. fia/m'zgzzez BY w/ ATTORNEYS RAILWAY CAR CONSTRUCTION BACKGROUND OF THE INVENTION The present invention relates to a railway car construction and more particularly to a novel side construction of hopper cars and the like.
The present invention represents an improvement in the construction of hopper cars wherein there is commonly employed in the prior an an arrangement such that the side of the car is supported directly on the top bolster cover plate thereby permitting the side sill to be tied directly to the bolster. The side of the care extends all the way to the bottom of the side sill which lies substantially in the same horizontal plane as the top of the underframe of the car.
This arrangement as employed in the prior art uses an excessive amount of material in the sides of the car since the lower portions of the sides actually serve no useful purpose in a hopper car construction. The material used in the sides may be relatively expensive such as aluminum, and accordingly, this type of construction substantially increases the cost of the car. Furthermore, this excess material increases the light weight of the car.
Additionally, the conventional hopper car construction involves excessive fabrication costs since considerable welding of parts to one another is required.
A further disadvantage of known constructions of hopper cars is the fact that the underframe arrangement is relatively complicated and expensive.
SUMMARY OF THE INVENTION In the present invention, the sides of the hopper car do not extend downwardly so as to be in substantially the horizontal plane as the top of the underframe of the car. Transition means is supported on the underframe substantially above the bolsters at either side of the car and extending upwardly therefrom. The sides of the car are supported by the upper portions of the transition means whereby the lower edges of the sides of the car are disposed at a horizontal level substantially above that of the top of the underframe.
Accordingly, the arrangement of the present invention employs less material in the sides thereof since the side sheets are of less vertical dimension than that required in the prior art, and less material is required in the side posts. A substantial saving in cost is thereby obtained since less of the relatively expensive material is employed in the sides of aluminum cars without in any way decreasing the efficiency or operability of the car. Additionally, the light weight of the car is reduced.
The construction of the present invention also reduces the fabrication costs of the car since less welding of components is required.
The present invention also permits the use of a simplified underframe construction, and the upper structure of the car may simply be lowered into place and bolted in operative position.
The transition means of the present invention also enables smooth transfer of stresses between the bolsters of the underframe and the sides of the car. Additionally, conventional wrecking equipment and hydraulic jacks may readily be employed with the invention construction for jacking, maintaining and rerailing a car, in the same manner as has been done in the past.

FIG. 2 is a sectional view on an enlarged scale taken substantially along line 2-2 of FIG. I looking in the direction of the arrows;
FIG. 3 is an enlarged side view of one of the transition means of the present invention;
FIG. 4 is a sectional view taken substantially along line 4-4 of FIG. 3 looking in the direction of the arrows; and
FIG. 5 is a sectional view on an enlarged scale taken substantially along line 5-5 of FIG. 3 looking in the direction of the arrows.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views, a covered hopper car is illustrated in FIG. I and is indicated generally by reference numeral I0. The car includes a more or less conventional underframe 12 having a first truck and wheel assembly 14 supported in the usual manner at one end of the car and a second conventional truck and wheel assembly 16 is supported at the opposite end of the car.
A first pair of stub side sills 20 are provided at opposite sides at one end of the car, one of these stub side sills being visible in FIG. I. A transversely extending body bolster 22 is incorporated in the underframe structure and has its opposite ends in abutting relationship with the inner surfaces of stub side sills 22.
A similar pair of stub side sills 24, 241 are supported by the underframe at the opposite end of the car. A transversely extending body bolster 26 is incorporated in the underframe structure and has its opposite ends in abutting relationship with the inner surfaces of stub side sills 24, 24'.
A pair of comer posts 30 are supported at one end of the car, one of these corner posts 30 being visible in FIG. 1. A ladder means 32 is interconnected with and disposed adjacent end post 30. A similar pair of end posts 34 are provided at the opposite end of the car, and a ladder means 36 is interconnected with and disposed adjacent end post 34.
The roof of the car is indicated generally by reference numeral 40, and a longitudinal running board 42 extends the length of the car.
The sides of the car are substantially identical, one of the sides being visible in FIG. 1 and including side sill means 50 extending throughout the length of the side of the car, a side sheet 51 being interconnected with and extending upwardly from the side sill. The upper edge portion of the side sheet is in turn interconnected with a side plate 52 extending along the length of the upper portion of the side of the car.
A plurality of intermediate side posts 54 are secured to the outer surface of the side in the usual manner. A first bolster post 56 is secured to the outer surface of the side substantially directly over the body bolster 22. A similar bolster post 58 is secured to the outer surface of the side substantially over the body bolster 26.
A first hopper of conventional construction is indicated generally by reference numeral 60, and is provided with the conventional closure means 62 at the lower end thereof. A portion of another hopper is indicated generally by reference numeral 64, the remainder of this hopper having been broken away. It is apparent that the car may incorporate any suitable number of hoppers, and in a typical example the car may be provided with three hoppers.
Referring now to FIG. 2, the laterally extending body bolster 26 includes a bottom cover plate 66 and a lower web 68, the bolster being interconnected with the longitudinally extending center sill indicated generally by reference numeral 70. A top cover plate 72 is provided on bolster 26. The stub side sill 24 disposed at the opposite side of the car is substantially identical with the stub side sill 24 previously described.
A bolster upper web 76 extends upwardly from the bolster top cover plate 72 to the underside of the sloping end floor sheet of the car, and upwardly extending stiffener posts 78 are suitably secured to the outwardly facing surface of the end floor sheet. The end floor sheet is provided with a pair of cutouts 80 at opposite sides thereof for receiving the upper flange portion of the transition means hereinafter described as well as the lower portion of the side sill means interconnected therewith.
A pair of roping devices 82 and 82' are secured to the outwardly facing surfaces of stub side sills 24 and 24' respectively, these roping devices serving as means for towing the car. As seen in FIG. I, the roping device 82 is disposed substantially over the body bolster 26 and a pair of arrows are provided immediately beneath the towing device 82 these arrows indicating the points at which jacking of the car should be carried out. A similar pair of towing devices are provided at the opposite end of the car, one of the towing devices 84 being visible in FIG. 1. Similar jacking arrows are provided beneath the towing device 84.
Four transition means are provided, these transition means each being supported by the underframe substantially over one end of an associated body bolster. The transition means are provided at the four corners of the car. Two transition means 90 and 92 at opposite ends of the car are illustrated at one side thereof as seen in FIG. I. These transition means serve to support the side of the car such that the lower edge of the side of the car is supported at a horizontal level substantially above the upper surface of the underframe, as is clearly apparent in FIG. 1.
Referring now to FIG. 2, a transition means 90 substantially identical with transition means 90 is disposed at the opposite side of the car and substantially directly over the body bolster 26.
The construction of transition means 90 will be specifically described, it being understood that each of the transition means is of the same construction.
Referring now to FIGS. 3-5 inclusive, transition means 90 includes a main substantially vertically extending wall portion 100 which joins with a normally extending lower flange 102. Lower flange 102 has a plurality of holes 104 formed therethrough at spaced positions therealong for attaching the flange to the underframe of the car as hereinafter described.
Transition means 90 also includes an upper flange 108 which may be secured to the upper end of wall portion I by longitudinally extending fillet welds 110 as seen in FIG. 5. Flange 108 has a plurality most clearly in FIGS. 3 and 4 for attaching the upper flange to the side sill means of the associated side of the car.
The transition means formed of a relatively strong material such as steel or the like. It will be noted as seen in FIG. 5 that the transition means is of generally channel-shaped construction, and if desired, the transition means could be a channelshaped pressing rather than comprising separate interconnected pieces as illustrated.
The outer end surface 120 of the transition means slopes downwardly and outwardly away from the center of the car as seen most clearly in FIGS. I and 3. The inner end surface of the transition means extends vertically upwardly for a short distance as indicated by reference numeral 124 as seen in FIG. 3, and then slopes inwardly and upwardly along the portion 126 thereof to terminate in a portion 128 of relatively small vertical dimension. This sloping inner end surface defines a tapered area A of the vertical wall portion 100 which serves to properly distribute the loads between the underframe and the side of the car.
It will be noted that the upper flange 108 of the transition means is of considerably greater longitudinal dimension than the upper edge of the side wall portion 100. This extended length of the upper flange provides a greater area for connection of the flange to the aluminum side sill means hereinafter described, permitting a greater number of bolts to be interconnected between the side sill means and the transition means to insure a good connection with the side sill means.
Referring again to FIG. 2 of the drawings, the components illustrated at the right hand side of this Figure have been given the same reference numerals primed as the corresponding components at the left side of the figure. The transition means 90 and 90' are supported by the underframe structure over the body bolster, the lower flanges 102 and 102' resting upon the top cover plate 72 of the bolster as illustrated, a plurality of mechanical fasteners 120 and 120 extending through the holes provided in the lower flanges of the transition means and aligned suitable holes provided in the top cover plate 72 as well as the stub side sills 24 and 24'.
Side sill means 50 previously described is an angle member including a vertically extending leg portion 126 and a horizontally extending leg portion 128. The leg portion 128 is provided with a plurality of holes formed through longitudinally spaced portions thereof adapted to be aligned with the holes 112 provided in the upper flange of the transition means 90. A plurality of mechanical fasteners 130 extend through the aligned holes in leg 128 and flange 108 for securing the side sill means to the upper portion of the transition means. In this manner, the side of the car is supported by the transition means interconnected with the lower edges thereof at opposite ends of the car.
It is apparent from FIG. 2 that the side componentsat each side of the car are interconnected in the same manner with the transition means, and it will further be noted that the hopper walls intersect the sides of the car at points 134 and 134' just above the side sill means at opposite sides of the car.
As this invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, the present embodiment is therefore illustrative and not restrictive, all changes that fall within the metes and bounds of the claims or that form their functional as well as conjointly cooperative equivalents are therefore intended to be embraced by those claims.
