LOAD BRACING MEANS FOR RAILWAY CARS AND OTHER TRANSPORT John McMullen, Buffalo, N. Y., and John '1'.

Gallagher, Chicago, Ill.

Application July 28, 1932, Serial No. 625.404 6 Claims. (01. 105-369) This inventionrelates to adjustable load bracing means for railroad cars and other forms of merchandise transport.

One of the principal objects of the invention is to provide a reliable and efficient load bracing means, in the form of a gate or bulkhead, of simple and economical construction for refrigerator and other freight cars, that is capable of bracing against stacked materials, a portion of or anentire load as occasion demands, an exampleof load being crates or boxes of fruit or vegetables, so that they will not be shaken or violently disturbed, broken or injured in transit to destroy the same and involve a heavy financial loss, such as commonly occurs with loosely packed loads.

The invention provides essentially two 'or more similar gates or partitions or other bracing structures upon opposite sides of the car doors, for bracing the fruit or other contents packed in the opposite ends of the car so that it will not chuck or move about in transit; said gates being hung underneath the roof of the car so they can be swung up out of the way when not required for use, and means being supplied whereby the said gates may be moved longitudinally of the car 7} against the crates or boxes of fruit or other mere chandise to prevent the same from knocking about in the transit oscillations and shocks of the car.

And the invention may also be said to consist in so numerous other features m the construction,

combination and arrangement of the several parts. to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appendedclaims.

In describing our invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 12 is an edge view on the line 12, 12, of Figure 9, with the side of the car in section.

In the present embodiment of our invention, ,the load bracing devise is adapted for permanent connection to a'refrigerator or similar car A, and is adapted for anchoring and holding loads or parts of loads of stacked materials of any kind of merchandise, but with particular reference to the bracing of fruit packages assembled in standard size boxes or crates B and. loaded in both ends a of the car A through the central door, as b. A pair of the gates or bulkheads 1 is employed when bracing a full car, or when the ends of the car are only partially filled, these gates 1 being adapted to be forced tightly against the packed merchandise and then fastened in this position, after which the space between the two gates nearest to the door can be filled in with additional boxes, etc.

The installation of the bracing devices in a car or other transport is made complete and can remain in the car during its entire useful life. In ordinary transit, when the car is deadheading,

which does not require the use of the bracing mechanism, and also during the access of loading the merchandise into the car through the door, the gates or bulkheads are placed in the upper part of the car in a horizontal position under -the roof against the ceiling where they will be out of the way and the car operated just exactly as if they were not-present.

The entire space taken up by the gates in this horizontal position is only a few inchesbelow the ceiling, so that it is safeto say that no restrictions whatsoever would have to be pl ced on cars equippedwith our improved bracing devices in the kind of merchandise they would carry or the manner of their use.

roof above the longitudinal tracks 2. There is a' gap at 24 between the ends of tracks 2 to allow the projecting lower ends of gates 1 to pass through gaps 24 to a point above the tracks, to allow the gates to be upheld in the horizontal position on the trackways, which is effected by resting the projecting lower ends of the gates on the tracks 2 after these gates have been so lifted and the projecting lower ends passed through these gaps and the gates then pushed into their idle position on the rollers so .as to carry the said projecting lower ends of the gates beyond the gaps where they can rest on the tracks. When the gates are being lowered from their idle position so as to take their vertical bracing positions against merchandise B, they assume various inclined positions which are shown in dotted lines. We proceed now to describe all the various parts of the mechanism in detail.

We are taking a typical refrigerator car as an example for illustration, because it carries so much perishable freight, which needs secure packing to prevent injury and loss. But while the bracing device is particularly adaptable for the shipping of fruit or the like in refrigerator cars, it can be used in any other position or situation or other kind of conveyance where bracing 'of this character is required. Accordingly we do not wish to be restricted to the details of the invention as herein described, except as they are necessarily embraced within the scope of the claims hereto appended.

A designates a refrigerator or other railway car of any approved construction, having the door 1) and the floor bottom construction 4, on which is usually placed the removable and adjustable slat flooring 5, arranged in foldable or other sections; in order to allow the cold air to freely circulate around the fruitor other crates B, or the 'Along each longitudinal edge of the car A, and along a central or median line, a toothed rack bar 3 is securely fastened to the car floor 4, the

, outer rack bars 3 being outside of the slat sec- 5 tions 5, and the central bar 3 being between them. see Figures 4 and 6, said rack barsbeing adapted to be engaged by bolts or other locking means on g the bottom of the gates 1. 1

The gates 1 are fully shown in Figure 1 and in the sectional views in Figures 5 and 6. These gates may vary much in their details, but we prefer to have them of an open work structure, to allow a free circulation of the air, and with this end in view, we use L or Z bars 13, in the angles of which are. placed upright wooden rails 14 which are held firmly against the adjacent faces of the 2 bars by the various series of slats. The upper ends of these combined 2 bars and upright wooden rails are securely fastened together into a single structure by the upper angle beam 10, and their lowerends are similarly united by a bottom angle beam 12. Thebseries of wooden uprights 14 on one side of the 2 bars 13 areunited by a series of slats 15, and the other series'of rails 1 n"the-"other side of the 2 bars are united 3 then series of slats 15; Thus the general 4 st ture 'ofthe gate is rectangular, and it may 'jocciipy a vertical position where'it is active, or a horizontal position where it is out of the way,

like, packed in the car on this open work floor.

and it can be easily shifted from one position to the other.

The parallel horizontal slats 15 on both sides of the uprights 14 and 2 bars 13 stop short of touching the side walls of car A so as to leave a sufficient space between the ends of these slats and the sides of the car for easy movement of the gate; but the lower connecting angle beam 12 extends beyond the ends of the slats l5 and its ends come much closer to the car walls, and these ends are provided with'suitable castings or frames 23 fastened thereto, or the'material of the ends of beam 12 may be bent or shaped for the purpose of carrying the vertical bolts 16 having han-' dles 17 that work in slots 18. These bolts are adapted to drop into the teeth of floorrack bars 3 after the gate is in its vertical position ,to be locked against the crates. The extended ends of the lower angle piece 12 with the bolt frames 23 are directly above the outer racks 3 so that the ends of the bolts can drop into the rack teeth, (see Figure 5). The handle 17 enables the bolt 16 to be lifted out of the rack 3, and by turning the handle .17 in'the slot 18 the bolt 16 can be kept raised out of the teeth of rack 3. At the center of the beam 12 is another similar bolt frame' 23, whose bolt 16 engages the teeth of 'the middle rack 3 so as to more securely fasten the gate in position. Thus three lower points are provided at which three bolts are thus located 105 to effectuate the triple locking. Of course the bolts'are only examples of fastening devices that. may be used. Others may be substituted, and in place of the racks 3 on the floor, similar racks may be secured to the sides of the car, in which case the bolts at the ends of the beam 12 would have to be arranged to slide horizontally instead -of vertically so as to laterally enter the teeth of the racks; and other changes may also be made.

The top beam-10 of the gate is provided at each end with an attached casting 22, which may be made as an integral part or otherwise of beam 10, and either from said castings 22, or from the or other means to the walls of the car, (see Figures 5 and 12) and on their outer edge they have the vertical toothed flanges 6, whose-teeth may be engaged by horizontal bolts, as 20, carried in the castings 22, and provided each with a bent operating handle 21. These parts are all clearly portrayed in Figures 4, 5, '7, and 8. When the gate is lifted at its bottom from a vertical to a more or less inclined position, the'top end will roll by virtue of rollers or wheels 9.0n track 2 inside of rack 6, and thus the gate 1 can be adjusted back and forth, or caused to press more or less closely against the packed merchandise. When the gate is lifted and placed in a-horizontal position the pivoted angular finger 19 on one or both ends of gate beam 10, as seen in Figures '1 and 8, can be caused to engage one of the teeth in rack 6, so that the gate is thus held firm and prevented from being shaken or jolted out of place.

The pivoted finger or catch 19 is held on the end of beam 10 by a horizontal pivot pin which allows it to swing up or down in a vertical plane opposite to the flange 6, and it has a right-angled end which drops into an indent or ,hotch in the -,merchandise are placed the gates is being transferred from its working vertical to its horizontal idle position, or vice versa, as indicated in the diagrammatic views. These gaps can be filled with short track sections 8 similar to the track 2, so as to make the latter track continuous after the gate has been placed in its idle horizontal position, and permit rollers 9 to travel along its path on track 2 for alonger, distance on track 2. Piece 8 is shown in detail' in Figure 11, and in position on track-2 in Figure 10, where the ends of section 8 are seated on supplemental supports 7 secured under the ends of track 2 and projecting slightly beyond the ends'into the gap 24, as seen in Figures 9 and 10, and in the edge view of Figure 12.

The operation of the bracing gates may be briefly described as follows: When the gates are not required for use, "they are swung up against the ceiling or inner side of the roof. of the car by lifting them on the rollers 9 as on pivots, the projecting ends of beam 12 passing through gaps 24 so that the gates may assume their inoperative horizontal position, one or both of them. Because when the gates are thus lifted, and the projecting ends of beam 12 passed through-gaps 24, the gates may then be adjusted lengthwise by rolling them on their rollers 9 until the projecting ends of beam 12 have been moved beyond the gaps 24, and then these ends may be caused to rest on the tracks 2 and thus support the gates in the raised position. And when the gates are so placed the latch 19 pivoted on the top part of the gate, (see Figures 7 and 8), may engage teeth 6 to render the gate immovable; and the track sections 8 may be put into place to obviate the discontinuity of said tracks.

When the gates are required for bracing use and the boxes or crates of fruit have been piled into the opposite ends of the car, the gates are separately let down-after releasing catches 19 and removing track fillers 8. When the gates have been swung down they will be pushed firmly against the boxes in opposite ends of the car,

the gates traveling on the tracks 2 towards and.

against the boxes, and when a gate is pressing against the pile pf boxes with sufllcient strength its upper end may be secured in place by interlocking bolts 20 with racks 6, andits lower end may be secured in place by interlocking its bolts 16 with racks 8, all three racks, the gatebeing then vertical as seen in Figures 2 and 3. After one gate has been localized rigidly against the merchandise B in one end of the car, the other gate may be similarly localized against the merchandise Bin the other end of the car.

When loading the car the boxes, crates or other in position in the ordinary manner. a, ,5

By the useof our present improved bulkheading means the car A may be loaded with boxes,

--'s ifrates," or thelikegforiany desired portion of its length and the merchandise heldsecurely against fnioveme nl irby clamping and locking one of the F-s'a'tes' against it, as described. This enables the shipper to load a fraction of a carload, and admits of portions of the shipment being delivered at various points, the gate being swung against the ceiling of the car to admit of the removal of the" desired part of the shipment and then restored in its clamping position against the outermost part of the remainder of the load. After both "ends of the car are suitably loaded, and the gates locked against these loads, the space between the gates and opposite door b maybe filled full of other merchandisefas much as desired. Further it will be found possible to arrange more than two gates, so as to hol more than two piles'of merchandise, in which case the details will be changed as far as may be necessary to make this possible. h

Many changes may be made in the details with out departing from the invention set forth in the claims. The gate structure may be varied with many different features. The locking or fastening means at top and bottom of the gates may be widely varied and substituted with othemequivalent devices.

tions may be adopted Instead of single rollers 9 on each track, as shown, there may be pairs of rollers on each track, .the same carried in a frame or holder pivoted, hung or otherwise sup.- ported on the ends of the gates, so that the two These gates may be appl ed to any kind of carrier or car, and other modificarollers on each track may run easily on the track in line with each other.
