GUIDE RAIL STRUCTURE FOR RAILWAY FLAT CARS nite States atent U.S. Cl. 105-368 12 Claims ABSTRACT F THE DISCLOSURE A railway flat car having a guide rail structure on its deck comprising guide rail sections movable between a position extending longitudinally of the car for transporting roadway vehicles and a position extending transversely of the car for supporting ladings, such as containers or lumber, on the deck. The guide rail structure includes a pair of spaced guide rails each -having a plurality of sections of a length less than the width of the deck, and means mounting the guide rail sections for movement between a position in which the sections extend longitudinally of the deck and a position in which the sections extend transversely of the deck. The at car is adapted to carry a trailer secured to a hitch when the hitch is erected and the rail sections extend longitudinally of the deck. When the hitch is collapsed and the rail sections are moved to a position extending transversely of the car, ladings, such as containers or lumber, may be positioned on and supported by the guide rails.
Background and description of invention Guide rails are employed on railway dat cars used in piggyback service to guide the roadway wheels of trailers and tractors upon movement of the trailers and tractors along the at car. Heretofore, side sills projecting above the deck of a railway flat car have for-med guiding surfaces for roadway vehicle wheels or tires. Today, especially in dat cars adapted for carrying both containers and trailers, so-called ush deck cars are being employed in which the side sills do not project substantially above the deck surface of the railway flat car. By the use of such flush deck cars, laterally movable arms of cranes or the like may be easily positioned beneath containers for loading and unloading purposes. Thus, it is necessary to have separate guide rails on such ush deck cars for guiding and centering roadway vehicles on the railway dat car.
To secure trailers in transit on the railway flat car, hitches are mounted on the deck to secure the kingpins of the trailers, and the guide rails center the trailers on the railway car deck. When other ladings, such as containers and lumber, are transported on the railway car, the hitches are moved to a collapsed position on the deck. It is highly desirable to have the lading spaced from the deck of the car so that unloading and loading equipment, such as lforklift trucks, overhead cranes and the like, may engage the underside of the ladings, such as containers. Thus, the guide rails of the present invention are adapted to be positioned to extend in a direction transversely of the car and to project from the deck a distance greater than the height of the collapsed hitches for supporting containers on the railway dat car. Laterally movable arms of cranes or the like may then be easily positioned -between the containers and the deck of the railway flat car for loading and unloading purposes.
Brieiiy described, the present invention comprises a railway flat car having a generally fiat deck, a pair of spaced, generally parallel guide rails extending longitudinally generally the length of the deck and adapted to center the wheels of roadway vehicles, at least one hitch mounted on the deck between the guide rails for movement between collapsed and erect positions and adapted to engage the kingpin of a trailer to secure the trailer for transit on the railway car, each of said guide rails including a plurality of aligned rail sections each being of a length less than the width of the deck, and means mounting each rail section for movement between a position in which each section extends longitudinally of the deck and a position in which each section extends transversely of the deck, the hitch in collapsed position projecting from the deck a height not greater than the height of said rails above the deck, the flat car being adapted to carry a trailer secured to said hitch when said rail sections extend longitudinally of the car and Ibeing adapted to carry containers supported on the guide rail sections when the guide rail sections are positioned to extend transversely of the deck and the hitch is in a collapsed position on the deck of the railway car.
The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.

Referring now to the drawings for a better understanding of this invention and more particularly to the ernbodiment shown in FIGURES 1-8, a railway iiat car is generally indicated at 1t) and has a generally flat deck 12. Spaced lalong the length of deck 12 along each side thereof are a plurality of stake pockets 14 employed to secure ladings on deck 12. Mounted on deck 12 are collapsible trailer bitches 16 shown in a collapsed position. Hitches 16 are collapsible and movable between an erect position to secure the kingpin of `trailers T or the like as shown particularly in FIGURE 7 and a collapsed inoperable position as indicated in FIGURE 8. An example of a collapsible hitch 16 which may be employed is shown in U.S. Patent No. 3,225,707 dated Dec. 28, 1965, and entitled, Collapsible Support, the entire disclosure of which is incorporated by this reference.
Mounted on deck 12 is the guide rail structure forming the present invention and comprising a pair of spaced, generally parallel guide rails 18 extending longitudinally of deck 12 as shown in FIGURES 1, 1A for guiding the wheels of roadway vehicles along deck 12. Each rail 18 comprises a plurality of adjacent guide rail sections or segments 20, 22 and 24 of different lengths as indicated in FIGURES 2 and 2A. Intermediate guide rail sections 20 are positioned at areas remote from the -sides of hitches 16 and are of a length substantially equal to onehalf the width of deck 12. Guide rail sections 22 are positioned adjacent the sides of hitches 16 and are of a length less than one-half the width of deck 12 in order to extend between bitches 16 and the sides of car 10 as shown in FIGURES 2, 2A, and 3. Each end guide rail section 24 is positioned adjacent an end of deck 12 and forms Van end of the associated guide rail 18. While guide rail sections 20, 22, 24 are of different lengths, each guide rail section is similar in operation and is mounted for movement between a guiding or centering position as shown in FIGURES 1, 1A, `and 7 in which the section extends longitudinally of deck 12 for contacting and guiding tires of roadway Vehicles, such as trailers, and a lading support position in which the section extends transversely of deck 12 for supporting containers or the like as shown in FIG- URES 2, 2A and 8. A typical intermediate section 20 is illustrated in FIGURES 4, 5 and 6 and is generally channel-shaped in cross section having a support base or lower leg 26 supported on deck 12, an upwardly directed web 28 inclined at Sii, and a generally horizontal upper leg 32. Spaced along the length of section 20 are stifteners 34 secured between legs 26 and 32. A pin 36 extends through base 26 and deck 12 to mount section 2t) for pivotal movement between a guide position as illustrated in FIGURES 1, 1A and a lading support position illustrated in FIGURES 2, 2A. To releasably secure section 2@ at guide and support positions, manually operable catch pins generally indicated 38 are mounted for rotation on projections 46 secured to the end stiiteners 34. A laterally extending head 42 on each catch 38 is positioned beneath deck 12 as indicated specically in FIG- URES 5 and 6 and is adapted to be aligned with an elongate slot 44 in deck 12 for retraction of catch 38 and pivoting of guide rail section 20. A circumferential collar 46 on pin 38 rests against base 26 and limits the vertical movement of pin 38. A handle 48 on pin 38 may be gripped for manually rotating pin 3S to a locked or unlocked position. As shown in FIGURE 4, one pin 38 is ina locked position and the other pin 38 is in unlocked position.
As shown in FIGURE 7, trailers T are secured to hitches 16 for transit on railway liat car 12 and the guide rails 1S extend longitudinally of the railway car for guiding and centering roadway vehicles on deck 12. When guide rail sections 2t), 22, 24 are pivoted to extend in a direction transversely of deck 12 as shown in FIGURES 2, 2A and 8, lading, such as containers or banded lumber L, may be supported on the guide rail sections. Suitable tie-downs may be provided and anchored to stake pockets 14 or stakes may be mounted in stake pockets 14 to limit the lateral movement of the lading supported on the guide rail sections. The height of guide rail sections Zt), 22, 24 above deck 12 is greater than the height of hitches 16 in collapsed position as shown in FIG- URE 8. Thus, the lading is supported entirely on the guide rail sections and is spaced slightly from the upper surfaces of the collapsed hitches 16 in the lading support position of the guide rail sections.
Referring to the embodiment illustrated in FIGURES 9-13, guide rails 18A extend longitudinally of deck 12A in the roadway vehicle guiding position shown in FIG- URES 9, 9A and include intermediate guide rail sections 20A of a length slightly less than the width of deck 12A. Each section 211A has an arm 5t) secured thereto and extending generally perpendicularly to the longitudinal axis of section 20A. Each arm 50 is mounted for pivotal movement at 52 to deck 12A vbetween the position shown in FIGURES 9, 9A and the lading support position of FIGURES 10, 10A. Referring particularly to FIGURES 1113, an extensible guide rail section is generally indicated 54 and is positioned adacent hitch 16A intermediate the length of car 19A.
