As shown in FIG. 5, the flat deck 12 has on opposite sides thereof downwardly projecting longitudinally extending side sills l3 and is supported on a center sill l4. Crossbearer supports 15 are suitably connected to the side sills l3 and the center sill Id. The center sill 14 also includes a bottom plate 16 on which a sliding sill 117 is positioned. The sliding sill 17 may be suitably connected to a cushioning arrangement (not shown) which protects the car and its lading against impact forces on the couplers (not shown) which are conventionally positioned at opposite ends of the center sill lid. The present flatcar may also include alternately, of course, end of car cushioning means instead of the sliding sill arrangement disclosed.

Referring now particularly to FIG. l, a set of container brackets lid is provided on the deck 12 on the left side thereof and a second set of container brackets 19 is provided on the right side thereof. The set of container brackets lltl comprises two pairs of stationary brackets 20 having pockets 2i, each pair of the set being longitudinally in alignment and being adapted to engage and support the corners of a large container, as best shown in FIG. 2. The set 118 also includes a pair of movable intermediate brackets generally designated at 22 and being more clearly shown in FIGS. 6 and 7. The intermediate brackets 22 each comprise a track angle 23 suitably connected to the side sill 13, as best shown in FIG. 7. A track angle 24 is laterally spaced and suitably connected to the deck 12 in parallel relation with respect to the track angle 23. The track angle 23, as shown in FIG. ti, is provided with an aperture 25 and the track angle 24', is also suitably apertured (not shown) to receive a hinged 'stop 2d. The stop 26 is pivotally supported by means of a pivot bracket 27 to the deck 12. A base plate 28 is slidably disposed in the track angles 23 and 24 and has supported thereon a lower bracket portion 29. An upper bracket portion is designated 30 and includes longitudinally spaced pockets 31 which are formed by means of a center abutment 32 and a longitudinally extending abutment 33, said abutments being disposed in T-shaped fashion. A hinge 3 1-, connecting bracket portion 30 to bracket portion 29, permits each upper bracket portion 30 to be swung in clockwise fashion from the position shown in FIG. 7 to an outofthe-way position. v

The set of container brackets 19 includes two pairs of sta-' tionary brackets 2%, the arrangement being best shown in FIG. l. The brackets 35 include pockets 36 which are adapted, as shown in FIG. 2, to support the four corners of a relatively large container. A pair of intermediate brackets 37 are positioned substantially at the midpoint between the pairs of brackets 35 as best shown in FIG. I. Each intermediate bracket 37 includes a base plate lil which is rigidly secured to the deck 12. The base plate 40 has rigidly connected thereto a lower bracket portion 41. An upper bracket portion d2 includes longitudinally spaced pockets 53 provided by a central abutment 44 connected to a longitudinal abutment 45 in T- shaped relation. The upper bracket portion d2 is suitably connected to the lower bracket portion ill by means of a hinge A6 permitting the upper bracket portion 32 to be hinged in a clockwise manner from the position shown in FIG. l2 to an out-of-the-way position. i

As best shown in FIGS. 1, 2, 3, and 4, a movable hitch is designated 50 and includes laterally spaced triangular shaped side walls 51 suitably connected by end walls 52. Hinge pins 53 at the upper ends of the sidewalls 51 pivotally support a top plate 54 having a kingpin receiving opening 55. The opening $5 also is provided with suitable clamping mechanism (not shown) which is conventional in the art for securely locking the kingpin of a trailer in the kingpin receiving opening 55.

As best shown in FIG. 8, a lock opening 56 is provided in the top plate 54 and a lever 57 includes a pin 58 slidably supported on one of the side walls 51 and which is adapted to be engaged within the opening 56 for maintaining the top plate 54 in a vertical nonuse position, as best shown in FIG. 2. The movable hitch 50 is suitably supported on wheels $9 and is guided by means of longitudinally extending guide angles 63. The four lower portions of the side walls Eil, as best shown in FIG. iii, are provided with semicircular abutments db and bi. As best shown in FIG. ll, two pairs of stops 62 are positioned in longitudinally spaced relation and the hitch 5i. is moved between the said stops 62 from one position to another. The abutments fill and till suitably engage the stops 62 for limiting the longitudinal travel of the trailer hitch Sll. A pair of clamping mechanisms 3- are also shown in FIG. 1 and each includes a hand lever 65 suitably pivoted to the deck, as indicated at as and having links 67 pivotally connected thereto. The links b7 are also slidably connected to a pair of sliding blocks 68 by means of a pivot arrangement 69.

The end of each sliding block 68 is provided with an arcuate recess 71 which, as best shown in FIG. 8, is adapted to engage the abutments 61 for suitably locking the movable hitch 50 in position against the stops 62. In FIG. 8, the movable hitch 50 is positioned against the stop 62 and when the hitch 50 is moved to the right, the abutments 61 engage the stops 62, and the blocks 68 of the other clamping mechanism 64 then are in engagement with the abutments 60. i

As shown in FIGS. 1 through 4, the deck 12 is provided with a stationary trailer hitch 72. This trailer hitch 72 is substantially similar to the trailer hitch 50 and includes a similar top plate 54. However, the trailer hitch 72 may be suitably bolted or welded .to the deck 12 of the car and would not include the wheels 59.

As best shown in FIG. 10, the walls 52 are also provided with cutout portions 73 and a U-shaped bracket is shown at 74. The bracket 74 is suitably hinged by means of hinge brackets 75 to the deck 12 and may be moved from a flat position on the deck 12 to the position shown in FIG. 10 wherein stops 76 engage the walls 52 to retain the movable hitch 50 in position shown in FIG. 2 between containers supported on the car in lengthwise spaced relation. A slide bolt 77 is slidable in a bracket 78 supported on the U-shaped bracket 74 and may be engageable with an opening 79, best shown in FIG. 8, provided in one of the end walls 52. A stop 80 in one position of the slide bolt 77 locks the bolt in the opening 79.

Referring now particularly to FIG. 3, a collapsible hitch designated 81 is positioned in an erect operative position in supporting arrangement with one of the trailers which are generally designated 85 and include wheel suspensions 86. The collapsible hitch 81 may be of a type shown in the H. S. Wille et al. U.S. Pat. No. 3,358,955, patented Dec. 19, I967 This type of hitch is described in said patent and details of its operation are amply disclosed and need not be further elaborated upon in this description. Similar conventional collapsible hitches, well known in the art, may be utilized in the particular arrangement disclosed in FIG. 3 which need not be of the type disclosed in the aforementioned patent. The collapsible hitch 81 generally includes vertical struts 82 pivotally supporting a top plate 83, said vertical struts being supported in an upright position by means of folding struts 84 which may be hingedly moved to collapse the stand to an ondeck nonoperative position.

TI-IE OPERATION In FIG. 2 the car 10 is provided for container operation and two large containers 87 are suitably supported on the brackets and 35, with the four comers of each container thus being firmly secured. During this arrangement the intermediate bracket arrangements 22 and 37 are hinged to an out-of-theway or non-use position. In the present industry, containers of this type are generally 40 ft. long, and if 20-ft. containers are desired to be transported, these being indicated by the reference character 88 in the dotted lines of FIG. 2, four containers can thus be supported. FIG. 2 shows the container 88 at the left end of the car 10 having opposite corners supported on the brackets 20. The other comers of said container are supported on the intermediate brackets 22 which also support the end corners of the second 20-ft. container. The other end of the second container. The other .end of the second container is supported by the other brackets 20. The third container 88 is similarly supported on brackets 35 and intermediate brackets 37 and the fourth container is, of course, also supported on the intermediate bracket 37 and the brackets 35 at the far right of the railroad car. In container operation the stationary hitch 72 has its top plate 54 disposed in an out-of-the-way position as indicated in FIG. 2. The collapsible hitch 81 is in a collapsed ondeck or out-of-the-way position, and the movable hitch 50 has been positioned between the adjacent brackets 20 and 35 and is locked in this position by means of the bracket 7 3, as best shown in FIG. 10.

In FIG. 3 the railway car 10 is shown in use for supporting three trailers 85, each trailer having, of course, a conventional kingpin, as best shown in FIG. 5, which is suitably clamped to the top plates 54 of the stationary trailer hitch 72 and movable trailer hitch 50. The third trailer is shown supported by the collapsible hitch 81 which has now been moved to an erect position and the kingpin of the third trailer is suitably engaged in conventional locking means (not shown) in the top plate 83. As shown in FIG. 3, the upper bracket portions 30 of the intermediate brackets 22 have been moved out of the way of the trailer suspension 86 of the leftmost trailer. Such lengthwise movement is limited by stops 9 and 90, shown in FIG. 6. The stop 26 is hinged out of the way to permit lengthwise movement and is returned into the aperture 25 to lock the assembly, including the bracket 30, in two positions.

In FIG. 4 the railroad flatcar is utilized for supporting two of the longer trailers 85, each being 40 ft. in length, one of the trailers being supported on the stationary hitch 72, the other being supported on the movable trailer hitch 50. In this position the movable trailer hitch 50 is moved against stops 62 located at the right side of the car and the right-hand clamping mechanism 64 is utilized to lock the movable hitch 50 in position. In the position shown in FIG. 3 the movable hitch 50 is locked against the stops 62 with the clamping mechanism 64 on the left-hand side being in clamping relation to maintain the hitch in position.

Thus, it is believed that the invention has been clearly described and the arrangement is such that versatility of trailer and container transport is accomplished. The railroad car thus is easily adapted for large and smaller containers and highway trailers to that an effective interchangeable arrangement is provided. Adaptation of the container brackets and the hitches can be quickly accomplished depending upon the type of operation desired.
