RAILROAD CAR FOR TRANSPORTING CONTAINERS BACKGROUND OF THE INVENTION This invention relates to railroad cars for transporting containers. In particular, it relates to a car for transporting standard type containers and at the same time transporting hopper type containers which can be unloaded while on the car. Thus, instead of merely providing a car which can transport the hopper type containers and unload them on the car, the railroad car of the present invention includes mounts suitable for transporting standard containers as well, thus making the car much more flexible and useful to the customer. Another important design objective is to minimize the weight and cost of the car.

It therefore is an object of the present invention to provide a railroad car for carrying containers having hoppers therein which can be-unloaded on the car.

Another object of the present invention is to provide a railroad car which in addition to transporting hopper type containers is capable of transporting standard type containers.

Another object of the present invention is to provide a minimum weight railroad car for transporting hopper type and/or standard type containers.

Other objects will be apparent from the following description and drawings.

DETAILED DESCRIPTION The railroad car of the present invention is indicated generally at 10 and comprises trucks having conventional wheels 22, side frames 24, journal boxes 25, truck bolsters 26, and body bolsters 28. (FIG. 10).

The car further comprises a conventional center sill 30 having mounted therein conventional coupling structure (not shown). Side sills 40 are provided along the sides of the car.

Mounted along the longitudinal length of the car are a plurality of container support members 50 which are mounted upon the deck of the car. These container support members 50 together with special container support members 55 found at the opposite ends of the car provide mounting means for mounting the hopper type containers 80 as shown in FIGS. 2 and 2A.

Also mounted along the longitudinal length of the car are a plurality of pedestals 60 which are utilized to mount standard type containers 90 upon the car, elevated from the car deck, as shown in dotted lines in FIGS. 2 and 2A.

Also mounted along the longitudinal length of the car are a plurality of transverse support means located generally beneath container support means 50 and pedestal support means 60.

The hopper type containers comprise hoppers 82, having discharge outlets 84 comprising valves 86 having handles 88 for opening the same. The containers have support legs 87,89 which support the containers upon the deck, which may extend transversely across the deck when the containers are mounted upon the car.

Referring to FIGS. 5 through 7, leg 89 is welded to leg 87 along line 879. An opening 871 is provided in leg 87 to receive container locking means to be described hereinafter. The hopper type containers may be, for example, about l5 feet, 3 inches in length and about 8 feet wide. A lower portion 892 of leg 89 extends across the car.

Container support means 50 comprise an angle base support 502 having a horizontal portion 503 upon which the container legs are mounted on the deck. An end plate 504 is also provided having a lower portion 505 and an angle contour 506 adapted to provide support for the legs 87. Container support means 50 further comprises a mounting means indicated generally at 530 upon which is mounted a container locking means indicated generally at 510. The container mounting means may comprise a plate 532 having affixed thereto by welding on appropriate fasteners one or more mounting supports 534.

The locking means utilized to hold the hopper type container in place may take a wide variety of forms. One example of a locking means which may be utilized is found in Grob et al. U. S. Pat. No. 3,391,654. Other examples include locking devices shown in U. S. Pat. No. 3,667,401 and in U. S. Pat. No. 3,525,307.

For illustration purposes, the locking device shown is that contained in ACF application Ser. No. 293,456. Docket No. 323 in the name of Robert R. Girard, filed on even date herewith. The locking device 510 comprises a locking arm 512 integral with a generally vertically extending web portion 514 integral with a weighted base portion 518, for example, having substantially identical weighted arms 519, as is described in detail in the said Girard application. A pin 536 passes through opening in supports 534 and through an opening 516 in locking device 510 to provide pivot mounting of locking device 510. As a member to be engaged, for example, a container or container leg such as 87 having an opening therein 871 descends into engagement position, the lower portion thereof 872 contacts the locking arm 512 and moves the same outwardly as the locking member pivots about the pin 536 until the opening 871 in container leg 87 is reached, after which the locking arm 512 springs back into the opening 871 in the container leg. A substantially horizontal locking surface 513 on locking arm 512 cooperates with a locking surface 533 on plate 532 to hold the container leg in position and counteract any tendency for the container to move vertically out of position, for example, during impacts. To remove the container leg it is merely necessary to move the locking member 510 into the upright position as shown dotted in FIG. 5, and the container leg may be removed vertically unobstructed.

As can be seen from FIGS. 1 and 1A, a plurality of openings 44 are provided in the deck of the car. It will be apparent that the discharge outlets 84 are located a reasonable distance above the deck of the car. Thus, if it is desired to unload the containers 80 while they are mounted on the car, the discharge outlet arm 88 can be rotated and passed into the openings 44 in the car deck and an appropriate outlet structure attached to the discharge outlets such as a flexible conduit and/or a pneumatic system and the containers unloaded.

The support structure 70 extending transversely across the car to center sill 30 below both locking means 50 and pedestal locking means 60 can be seen in FIGS. 1, 2 and 5-7. Support structure 70 comprises a crossbearer web 72 which extends all the way across the car, together with stiffening plates 74 and 76 welded or otherwise affixed thereto and to deck 42.

FIG. 7 shows the center sill structure 30 including upper tie plate 302, bottom tie plate 304, and side plates 306 and 308. Cross bearers 72 are welded or otherwise affixed to side plates 306 and 308. A central cross bearer 73 extends between plates 306 and 308 and is welded or otherwise affixed thereto. Below deck 42 longitudinal support stringers 310 pass through openings 312 in cross bearers 72 and are welded or 0therwise affixed thereto. It will be noted that transverse supports are provided preferably only below container support means 50 and 60 where the weight from the containers is transmitted to the car, thus minimizing the weight of the car. Also the use of angular support plates 74 and 76 in combination with cross-web 72 helps to distribute the weight of the containers and lading to car and reduces the need for additional cross bearers.

Turning now to FIGS. 3 and 4, the pedestal support means 60 is illustrated. A container seat 601 is provided having a generally horizontal portion 602 upon which standard containers 90 rest during transit. A pedestal end plate 603 is also provided which engages and/or supports a lower portion of the standard containers resting on seat 602. Pedestal mounting means 605 also are provided comprising a pedestal mounting plate 606 upon which are affixed, for example, by welding or other appropriate fasteners, one or more lock support members 607.

Mounted upon the plate 606 is an appropriate locking means 610. As described in connection with locking means 510, a wide variety oflocking means are suitable. By way of example the locking means described in Girard application Ser. No. 293,456 Docket No. 323 is illustrated. Locking means 610 may comprise a locking arm 612, an integral web portion 614 and a weighted base portion 618 having weighted arms 619 thereon, as described in connection with locking means 510. Locking member 610 is mounted upon a locking pin 609, which passes through openings in lock support members 607 and through an opening 616 in locking member 610. Containers are of rectangular or square shape and are preferably of standard size, for example, 30 X 8. The containers 90 may comprise four locking feet 910 at the corners integral with the container; for example, feet 910 may comprise a cast ing, welded or bolted to the container, having an opening therein 912 into a generally hollow portion 914. The feet 910 preferably include a lower ledge portion 916.

As described in connection with the aforementioned Girard application, the container may also be provided with an engaging means 920 for engaging the locking member 610 when the latter is in the elevated position and moving it to a locking engagement position. The engaging means 920 may comprise projections 922, for example, welded or otherwise appropriately fastened to the container at 924. In the event that the locking member 610 is in the elevated position, as shown dotted in FIG. 4, a portion of the container, preferably projection 922 may be utilized to engage base portion 618 to cause the locking member to pivot about the pin 609 and assume the position shown in solid in FIG. 4- As the container ledge portion 916 of foot 914 is lowered, it will engage the locking arm 612 and move the latter outwardly about the pivot pin 609 until such time as the foot has moved passed the locking arm and then the locking arm 612 will move back into the opening 914 and the container will be held in engagement. Impact forces urging the container out of engagement will be resisted by surface 633, preferably substantially horizontal on the mounting plate 606 and surface 613 of locking member also preferably substantially horizontal.

The containers may be removed by manually rotating the locking member about pivot pin 609 into the elevated position shown dotted in FIG. 4, and moving the containers vertically.

As far as construction at the ends of the car is concerned, it will be seen from FIG. 8 that the angle support 502 and end plate 504 preferably extend all the way across the car as shown at 502a, 503a (horizontal portion) and 504a respectively in FIG. 8. The continuation of these members across the end portions of the car provides transverse support. A comparison of FIG. 9 with FIG. 7 will show that the transverse portion of the car is foreshortened in the end portions; thus additional transverse support is preferably provided as shown in FIG. 8.

As shown in FIGS. 9 and 10, it will be seen that side sill 40 is modified to include an inclined portion 402 and an end portion 404. If the side sill 40 were continued to the end of the car with a vertical extent illustrated in the lefthand side of FIG. 10, the side frame 24 would run into the side sill around curves; as shown clotted in FIG. 9, side frame 24 may swing out laterally past side sill 40 around corners as indicated at 24a. Therefore, the inclined portion 402 and foreshortened portion 404 have been provided in the side sill to avoid this problem.

Also in FIG. 9, a body bolster 28 is shown having a lower body bolster plate 281 and a bolster support member 282 welded or otherwise affixed thereto. A

truck bolster 26 has a side bearing support 262 mounted thereon having a roller wear plate 266. Body bolster 28 has a wear plate support 284 and wear plate 286 which engages the truck bolster roller 266. Truck bolster 28 has a bolster center plate 288 which engages a body center plate 268 and a center pin is passed therethrough to obtain engagement between the body bolster and the truck bolster, as is conventional in the art.

By way of example, the hopper type containers have been described as having legs which rest on the deck and support the container body above the deck to allow unloading while still on the car. If desired, the hopper type containers could be mounted on pedestals of sufficient height to allow unloading on the car. Also the standard containers could either be mounted on higher pedestals or be carried on the deck with locking means mounted on the deck. in the latter case, pedestals for the hopper containers and locking means on the deck for the standard containers must be dimensioned so as not to interfere with transporting the other type of containers. Also. the locking means on the deck could be used to transport containers not having hoppers, but having dimensions corresponding to-the deck locking means. Thus, it is within the scope of the present invention to utilize the car in transporting entirely nonhopper type containers, should this alternative be attractive from a business view point. Alternatively, both the deck mounted (with legs) containers and the pedestal mounted containers may contain hoppers, and if desired may be unloaded on the car. Other modifications will be apparent to those skilled in the art.
