CONTAINER SUPPORT FOR RAILWAY FLATCARS 4 Sheets-$heet 4 Filed Jan. 17, 1966 INVENTOR ERLING MOWATT-LARSSEN United States Patent 3,354,838 CONTAINER SUPPORT FOR RAILWAY FLATCARS Erling Mowatt-Larssen, Hazel Crest, Ill., assignor to ACE Industries, Incorporated, New York, N.Y., a corporation of New Jersey Filed Jan. 17, 1966, Ser. No. 521,140 8 Claims. (Cl. 105-366) ABSTRACT OF THE DISCLOSURE A container support to support the lower corner of a container on a railway fiatcar. The support is mounted on a side sill for pivotal movement beneath the deck to an inoperable position, and catch means beneath the deck releasably retains the corner support in a stored position. An upper portion of the container support is mounted on a shear pad to permit a cushioned movement of a cont'iiliner upon buff and draft forces being exerted against t e car.

Background and description of the invention Containers transported on railway fiatcars may be supported on a separate support beneath each lower corner of the container with each support being separately mounted on the railway fiatcar. The container may be suitably secured to the support by a removable pin connection or the like. The present invention is directed to a container support or pedestal movable between an operable posimom on the deck of the railway fiatcar and an inoperable or stored position beneath the deck of the car. Such an arrangement permits the deck to be clear in the event the container supports are not employed.

It is an object of the present invention to provide a container support for supporting the lower corner of a container on the deck of a railway fiatcar movable between an operable position on the deck of the fiatcar and an inoperable position beneath the deck.

It is an additional object of this invention to provide such a container support which cushions the container upon impact forces exerted against the railway car thereby to absorb such impact forces.

Another object of this invention is the provision of such a container support which may pivot by gravity into a releasably retained inoperable position beneath the deck of the railway car after the support has been initially pivoted from the deck past a dead center position.

Briefly described, the present invention comprises a lower base support on the deck of a railway car mounted for pivotal movement between an operable position on the deck of the car and an inoperable position beneath the deck of the car, a releasable catch adapted to engage and hold automatically the base in stored position beneath the deck of the car when the base pivots by gravity beneath the deck, an upper container support carried by the lower base support on which a container or the like is adapted to be supported, the upper container support being mounted on the base support for cushioned movement in a direction longitudinally of the railway car upon the exertion of buff and draft forces against the railway car, and means on the upper container support to releasably secure the container thereon for transit.

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;

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 FIGURES 1 and 2, a railway fiatcar is indicated generally by the numeral 10 and has a pair of containers C mounted thereon for transit. Flatcar 10 has a deck or floor plate 12 and a box-shaped side sill 14 is secured beneath each side of deck plate 12 extending the length of the car thereby to form a flush deck surface. Additional stringers 16 extend the length of the car for reinforcing the underframe forming fiatcar 10.

Beneath each corner of each container C is a corner support structure generally indicated 17 and forming this invention. For purposes of illustration, only one corner support 17 is shown in FIGURES 3-6 as it is understood that each corner support is generally identical. Secured to the underside of side sill 14 for each corner support 17 are parallel extensions 18. Pivotally mounted on a shaft 20 extending between extensions 18 is corner support structure 17 adapted to support and secure a corner of container C. Each support structure 17 includes a base support 24 having an integral arm 26 overhanging side sill 14 and mounted about shaft 20 for pivotal movement. Side flanges 27 extend upwardly along each side of base support 24 and have inwardly extending end portions 28 as shown in FIGURE 5. A stop 29 is secured to the adjacent side sill 14 adjacent each side of arm 26 and acts to restrain movement of arm 26 in the operable position of support structure 17.

To secure support structure 17 to deck plate 12, lock ing pins 30 are mounted on lugs 32 projecting from the inner side of base support 24 and forming an integral part thereof. To permit pins 30 to move vertically, upper pm supports 36 integral with base support 24 having openings 38 aligned with openings 34 of lugs 32 to receive pins 30. To rotate pins 39, a handle 40 is provided on each pin 30 and is integrally connected to a collar 42 about each pin 30. To bias pins 30 upwardly, a compression spring 44 fits between each collar 42 and its associated lug 32. Projecting from the sides of pins 30 adjacent the lower ends thereof are oppositely facing locking lugs 46. As noted in FIGURE 6, openings 34 in lugs 32 are enlarged adjacent the lower ends thereof to receive locking lugs 46. Deck plate 12 has an elongate slot 48 beneath each pin 39 with the elongation extending transversely of car 10 as shown in FIGURES 3 and 5. To secure base support 24 to deck plate 12, each pin 30 is pushed downwardly by manual force exerted on handle 40 thereby to push lugs 46 through the subjacent elongate opening 48. Handles 40 are then rotated to move lugs 46 beneath deck 12 in a locked position. The broken line indication of handles 44) in FIGURE 3 illustrates the unlocked position of pins 30. Upon release of handles 40 after rotation, springs 44 urge pins 30 and lugs 46 upwardly into engagement with the underside of deck 12. Pins 30 aid in transmitting forces to deck plate 12 from support structure 17 upon impact forces being exerted against car 10..

Secured tobase support 24 is a Cushioning unit generally designated 50. Cushioning unit 50 is of the type to absorb imp-act forces from a shearing action and may be formed, for example, of a preformed molded unit comprising a plurality of horizontal metal plates 52 separated by resilient blocks or pads 54, such as, for example, rubber. A specific example of a preformed molded rubber shear pad which has been found to be satisfactory is sold under the trade name LORD by Lord Manufacturing Company, Erie, Pa., and has a length of around fifteen (15) inches, a height of around four (4) inches, and a width of around five and one-half /2) inches.

The lower horizontal plate 52 of cushioning unit 50 is secured to base support 24 by bolt 56. An upper container support 58 is secured by nuts 60 to bolts 62 integrally formed with the upper horizontal plate 52 of resilient cushioning unit 50. Container support 53 is generally hatshaped with outwardly projecting lower flanges 59 fitting beneath flanges 28 on base support 24. Support 58 is spaced from base support 24 a distance of around onehalf /2) inch so as to provide a vertical cushioning for container C. Projecting from container support 58 intermediate its length is a locking stud 64 having an opening 66 therethrough. Stud 64 is adapted to fit within an opening of corner fitting 68 of container C as illustrated in FIGURES 4 and 5. Container fitting 68 has side openings .70 aligned with opening 66 to receive a securing pin 72.

Rotation of securing pin 72 moves a retaining lug 78 thereon to a downward position thereby to prevent removal of pin 72 until lug 73 is disengaged. Spring clips 80 as shown in FIGURE 3 may be provided to hold pin 72 when the pin is not being employed.

Upon impact forces exerted upon car 10, container C will have a tendency to move relative to car and forces will be transmitted from the container to stud 64. Stud 64 has a cushioned movement relative to base support 24 as great as around eight (8) inches employing a cushioning unit 50 of the aforementioned dimensions. The weight of container C on shear pad 50 results in an increased stiffness in pads 54 thereby to provide an increased cushioning action.

When it is desired to employ flatcar 10 for purposes other than the transport of containers, such as, for example, the transport of trailers, container support structures 17 may be pivoted to an inoperable position beneath the deck of car 10. To release a support structure 17 from deck plate 12, handles 40 are first rotated 90 with lugs 46 clearing deck 12 and springs 44 biasing pins 30 upwardly. Then, support structure 17 may be manually pivoted about shaft to the broken line indication of FIGURE 6 and then released. The weight of support structure 17 causes it to pivot by gravity beneath a deck plate 12 and to be retained automatically without any manual locking being required. To stop the pivotal movement of support structure 17, a rubber block 83 is secured to plates 86.

To releasably retain support structure 17 in position, a catch 82 is pivoted on shaft 84 supported from plates 86 secured to the underside of deck plate 12. Catch 82 has a hook 88 extending outwardly of car 10 with a beveled edge 90. A pin 92 is secured to catch 82 and extends through a suitable opening 94 in a connecting plate 96 secured between plates 86. A suitable nut 98 retains pin 92 on plate 96. A compression spring 100 biased between plate 96 and catch 82 continuously biases catch 82 outwardly. A lever 102 has one end 104 fitting about pin 92 between nut '98 and plate 96 as shown in FIGURES 4 and 5. Lever 102 is supported intermediate its length by extension 108 having an opening 109 receiving lever 102 and acting as a fulcrum for lever 102. The other end 110 of lever 102 has an eye connected to an eye on a push rod 112 for actuation thereby. Push rod 112 is supported by arm 114 secured to car 10 and has a handle 116 for gripping.

To secure support 17 as shown in FIGURE ,6, pivotal; movement of support 17 by gravity eifects contact of beveled edge of hook 88 by stud 64 to urge catch $2 rearwardly against the bias of spring 100. When stud 64 clears edge 90, spring returns hook 88 to supporting engagement with the underside of stud 64 thereby releasably to retain support structure 17 in position as shown in FIGURE 6.

To release support structure 17 for pivotal movement onto deck plate 12, pull rod 112 is pulled outwardly to pivot lever 102 about its fulcrum at extension 108 thereby to move pin 92 and catch 82 rearwardly for releasing stud 64. Upon release of stud 64, support structure 17 may be pivoted manually onto deck plate 12.

From the foregoing, it is understood that the present invention provides a container support movable between an operable position on the deck of a flatcar and an inoperable position beneath the deck of the car, thereby to permit a flush deck surface for purposes other than the transport of containers. The container support may, when moved past a dead center position, pivot by gravity into an inoperable position beneath the deck of the railway car.

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

As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
