PATENTEU FEB 9 I97] J saw 100F10 RAILWAY CAR FOR CARRYING CONTAINERS OF VARYING LENG'II-IS IN TWO TIERS BACKGROUND AND DESCRIPTION OF THE INVENTION Heretofore, containers have been supported on railway cars in two tiers, such as illustrated in US. Pat. No. 3,389,663 dated Jun. 25, 1968. However, such arrangements for supporting containers in two tiers have not been able to accommodate containers of various lengths in two tiers.

The present invention provides a railway flat car for carrying containers of various lengths in two tiers. A side structure extends along each side of the railway car each having upper and lower longitudinally extending chord members. Three vertical crossframe structures are suspended from the upper chord members in longitudinal spaced relation and extend downwardly therefrom to a position below the lower chord members for supporting containers thereon at an elevation below the lower chord members. The crossframe structures are mounted for movement along the upper chord members for selective positioning longitudinally of the car to accommodate different lengths in a pair of lower containers in the lower tier, and pedestal support members on the upper chord members support upper containers thereon-over said pair of lower containers between the crossframe structures and may be adjustably positioned along the length of the car to provide a railway car for carrying containers of various lengths in two tiers.

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 one of various possible embodiments of the invention is illustrated,

FIG. I2 is a schematic view illustrating a loading arrangement in which a single container is in the lower tier and two containers are in the upper tier;

FIG. 13 is a schematic view illustrating another loading arrangement in which two containers of difierent lengths are in both the lower and upper tiers; and

FIG. 14 is a schematic view illustrating a further loading arrangement in which a single container is in the lower tier and three containers of different lengths are in the upper tier.

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

Referring now to the drawings for a better understanding of the invention and more particularly to FIGS. 1-3, a railway car is indicated generally 10 and includes a side structure indicated generally 12 on each side of car 10. A wheeled truck 13 is mounted adjacent each end of car 10. Each side structure I2 is a truss-type structure and includes respective upper and

lower chord members

14 and 16 of box-shaped cross sections. Diagonal strut members 18 and vertical strut members 20 connect

chord members

14 and 16. End cross members 2| and 22 extend between side structures 12 only at the ends of car 10. Top chord member I4 has an upper generally boxshaped guide 23 welded thereto at 24 with an upper slot 26 extending along its length. Spaced at l-foot intervals along the length of top chord 14 and guide 23 are circular openings 28. Railway car 10 may be of a length of around 89 feet.

Referring particularly to FIGS. 3-6, an end pedestal structure generally indicated 32 is adapted to support the lower comer of one container and an intermediate pedestal structure indicated generally 34 is adapted to support the lower comers of two adjacent containers. Each

pedestal structure

32, 34 is adapted for relative positioning along the length of upper chord members 14. Pedestal structure 32 comprises a generally cubical body portion 36 having an integral lower guide 38 fitting within slot 26 and received by coacting guide 23 on upper chord member 14. Projecting lugs 40 on lower guide 38 prevent removal of pedestal structure 32. Mounted within a central opening 42 of body portion 36 is a locking pin 44 adapted to fit within circular openings 28 spaced along the length of chord member 14. An actuating handle 46 is pivotally connected at 48 to pin 44 for movement of pin 44. An annular ring 50 is secured to pin 44 and a resilient hollow ring 52 fits around pin 44 against ring 50 and urges pin 44 to a locked position as shown in FIG. 4. A corner support 54 is mounted within an elongate slot 56 in body portion 36 and is adapted to support the lower corner of a container thereon as shown in FIG. 4. An extension 58 of corner support 54 is housed within body portion 36 and permit movement of support 54 between an operable support position shown in FIG. 4 and an inoperable retracted position shown in FIG. 5. For positioning of pedestal structure 32, handle 46 is moved to the position of FIG. 5 to withdraw pin 44 from opening 28. Then, pedestal structure 32 may be moved along top chord member 14 to a desired position at which pin 44 is vertically aligned with a subjacent opening 28. Movement of handle 46 to the position of FIG. 4 locks pedestal structure 34 in position. The intermediate pedestal structure 34 is similar to pedestal structure 32 except in regard to the container support. Container support 54A on pedestal structure 34 includes a pair of seats to support the lower comers of two adjacent containers. 'Ihus,

pedestal structures

32 and 34 may be positioned at selected intervals along the length of upper chord member 14 to accommodate containers of various lengths. The containers in the upper tier are designated C1 and the containers in the lower tier are designated C.

Suspended from upper chord members 14 are three

crossframe structures

60A, 60B, and 60C mounted between trucks l3 and adapted to support containers C in a lower tier between trucks 13. Each

crossframe structure

60A, 60B, 60C is generally identical and only crossframe structure 60C will be described in detail, it being understood that the remaining

crossframe structures

60A, 60B are similar. Crossframe struc ture 60C as shown in FIG. 2 includes an upper horizontal beam 62 and integral vertical side members 64 extending downwardly from beam 62 inwardly of adjacent side structures I2. Side members 64 extend downwardly to a position below lower chord members 16 and have laterally extending support ledges 66 thereon to support the lower corner of a container thereon. Containers C fit against side members 64 and are restrained thereby against longitudinal movement relative to railway car 10. Crossframe structure 60C is suspended from top chord members 14 on cross beam 62 and may be moved along the length of top chord members 14 for positioning at selected intervals. The locking means for securing crossframe structure 60C at selected intervals is similar to the locking means for the pedestal structures 32 and include a pin 44A adapted to fit within openings 28 as shown in FIG. 7. Handle 46A is actuated for locking and unlocking pin 44A. Guide 38A is secured to the lower surface of cross beam 62 and fits within slot 26 and guide 23 for sliding movement along upper chord member 14.

To guide and aid in supporting the lower portion of crossframe structure 60C and referring particularly to FIGS. 9-11, a lower guide 88 is secured to the lower surface of each lower chord member 16. A longitudinally extending slot 90 extends the length of guide 88. Openings 92 are spaced at l-foot intervals along the length of lower chord members 16 in vertical alignment with openings 28 in upper chord members 14. Outwardly extending guides 94 are secured to the outer surface of side members 64 and are received within guides 88 and slots 90. Pin 96 is received within opening 92 and is urged upwardly by resilient hollow ring 98 into locked position as shown in FIGS. 9 and 10. To release crossframe structure 60C for movement to another position, handle 100 may be gripped and pulled downwardly against the bias of resilient ring 98 to withdraw pin 96 from opening 92. Then pin 96 is rotated 90 and handle 100 engages the lower surface of guide 94 as indicated in FIG. 11. A washer 102 is secured to pin 96 to form an abutting surface for resilient hollow ring 98. Crossframe structures 60A and 608 function in a manner similar to crossframe structure 60C. However, intermediate crossframe structure 60B has a container support ledge 66A extending on both sides thereof to support two adjacent containers C.

As shown in FIGS. l214, railway car 10 is adapted to transport a variety of containers having different lengths by movement of

crossframe structures

60A, 60B, and 60C and

pedestal structures

32 and 34 along the length of the car. For example, a total of six containers might be transported with four containers Cl feet in length being in the upper tier and two containers C 27 feet in length being in the lower tier as shown in FIG. 1. FIG. 12 indicates a loading arrangement in which two containers C I around 40 feet in length are arranged on the upper tier and a single container C 40 feet in length is provided in the lower tier. When only one container is transported in the lower tier, an end crossframe structure is not employed and may be secured outwardly of the end of the container. The

pedestal structures

32 and 34 which are not employed when less than four containers are transported in the upper tier may be pivoted to an upward position as shown in FIG. 5 and will not obstruct the clearance between side structures 12.

FIG. 13 indicates a loading arrangement in which two containers C, one being 30 feet in length and the other being 20 feet in length, are transported in the lower tier and two containers C1, one being 40 feet in length and the other being 35 feet in length are supported in the upper tier.

FIG. 14 indicates another loading arrangement in which one container C 35 feet in length is supported on the lower tier and three containers C1, 20 feet, feet, and 40 feet in length, are supported on the upper tier.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results obtained.
