4 Claims. (Cl. 105-368) This invention relates to railyway cars for transporting highway trailers and more particularly to an improved side sill structure for such railway cars.

In railway fiat cars of a so-called low level type for transporting highway trailers, the floor or deck of the railway car is positioned at as low an elevation as possible in order to provide the necessary overhead clearance for the highway trailers through tunnels and the like where limiting overhead clearances are encountered. It is desirable to have means along the sides of the flat car to position and guide the roadway wheels of the trailers as they are driven onto the car. For this purpose the side sill structure on each side of the car extends above the elevation of the deck and acts to strengthen the underframe as well as to guide the roadway wheels. The present invention constitutes an improvement on the side sill structure for each side'of the railway car.

An object of the present invention is the provision of a low level flat car for carrying highway trailers and the like in which the roadway wheels of a trailer are guided along the sides of a railway car to position the trailer properly on the railway car.

A further object of this invention is to provide a side 7 sill structure for each side of a low level fiat car for carrying trailers and the like which car is light weight in construction and economical to manufacture.

An additional object of the invention is the provision of a side sill structure for each side of a low level flat car which reinforces the underframe against flexure while guiding the roadway wheels of highway vehicles to center the vehicles on the trailer.

The above objects are accomplished by the provision of a railway flat car having a side sill structure on each side of the flat car underframe extending substantially the length of the car, each side sill structure having a web with an upper portion extending above the level of the floor plate; and a rub rail structure on the inner surface of the web comprising a lower leg or flange extending over the floor plate, an upper flange secured to the Web and extending in a generally parallel relation to the lower frame, and a plate extending between and connecting the flanges for forming a rub rail against which the tires of a roadway vehicle may rub and be guided as trailers move along the railway car. Gther objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.

In the accompanying drawings, in which several or various possible embodiments of the invention are illustrated,

FIGURE 1 is a perspective view of a railway flat car embodying the present invention adapted to transport trailers;

FIGURE 2 is a partial section taken generally along line 22. of FIGURE 1;

FIGURE 3 is a fragmentary side view of one end of a sidesill structure or" the flat car shown in FlGURE 1;

FIGURE 4 is a top plan of the side sill structure shown in FIGURE 3;

FIGURE 5 is a section taken generally along line.55 of FIGURE 3;

FIGURE 6 is an enlarged plan of a modification of my "Ice invention in which the sections forming the rub rail structure are not rigidly connected to each other;

FIGURE 7 is a partial section of a modification of the present invention in which the side sill structure embodies a generally channel-shaped side sill; and

FIGURE 8 is a partial section of a further modification similar to the embodiment of FIGURE 7 and showing the side sill structure extending in a vertical direction.

Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to FIGURE 1, a railway flat car generally designated in has Wheel trucks 12 at each end thereof and is adapted to transport a pair of trailer (not shown). Collapsible trailer hitches H are hown in collapsed position on fiat car lit and when erected are adapted to secure the trailers on the flat car.

The underframe of railway car it) comprises a center sill generally designated 14 extending longitudinally along each side of the car, each having a vertical web 16 and a bottom cover plate 18. A plurality of transverse members or crossbearers 22 extend between center sills 14 and each is formed of a channel iron having upper and lower flanges 24. Cantilevered on web 16 of each center sill 14 is a plurality of stub crossbearers 26. Each stub cross bearer has a vertical web 28. Extending around the free edges of vertical web 28 is a continuous flange 30.

Forming the upper cover plate of center sill 14 is a lloor or deck plate designated generally 32 and having a portion cutout to form an intermediate opening 26. A Z member 34 extends around intermediate opening 36 and reinforces the adjacent edge of deck plate 32. The lower flange or Z member 34 is supported on crossbearers 22. For further details of flat car 10, reference is made to copending application Serial No. 293,092, filed July 5, 1953, and entitled Railway Car, the entire disclosure of which is incorporated by this reference.

The improved side sill structure which constitutes my invention is indicated generally at 38 and includes a vertical web 40 adjacent each side edge of deck plate 32 and extending upwardly therefrom. An inturned bottom base member l2. is integral with web 40 and has an upturned flange 44 engaging the underside of deck plate 32. Web 4% has an upper outwardly sloping portion 46. Mounted on the upper ed e of portion 46 is a tubular head 48 which extends the length of car 16.

Mounted on the inner surface of tubular head 48 and web 46 is a rub rail structure generally designated 50 and being generally channel-shaped in cross section. Lower leg or flange 52 of rub rail structure 50 is secured, such as by welding, along its outer edge to web 40, and upper leg or flange 54 is secured, such as by welding, along its outer edge to tubular member 43. Connecting

legs

32 and 54 is a connecting plate or web 56 formed integrally with

legs

52 and 54 thereby to provide a generally channel-shaped rub rail structure 50. A tire or wheel of a trailer is indicated at W and rubs against or contacts rub rail structure St) if the trailer is not properly centered on railway car 10.

Referring to FIGURES 3-5, rub rail structure 56 is formed in a plurality of longitudinally extending intermediate sections 57 and end sections 58 which are mounted on each side sill structure 38. The ends of

adjacent sections

57 and 58 are preferably butt welded to each other along seams 59 to form a continuous rub rail structure 50 whereby the rub rail functions as an integral structure under loading conditions and fiexure.

To guide the tire W as a trailer or tractor is being driven onto flat car ill, each end section 58 is tapered to merge gradually with vertical web 40 and tubular member 4-8 of the side sill structure. Tapered upper and

lower legs

52a and 54a of each section 58 are integrally connected by plate 560. Forming the outer free end of ni'ennierasand"web"40. "As'a tractor'or'trailer first reaches the end of flat car 10 and is not centered properly, the tire will first rub against or contact tapered end sec- "tio'rf58 and be 'guidedthereby'onto intermediate rub rail section 57.

As the force-"exertedby the tires'W is generally parallel to -1egs*'52"s4,the welds are primarily for the holding "ofrnU-rail 's't'rueture 50'in po'si'tion as only arelatively I srnall portion of the force exertedby tires W- is trans- "fnitt'ed to 'the welds.

I h h I "In the loaded 'flat car 10,' rnaXimurn tension is along the f-up'per'por'tion of side sill structure 38.
