Th r iie ta nt-b slinds w mor o ullr a -twi e a ant e ti m. iheiiol fq ie fi 3 tailed description of an illustrative embodiment as shown by the accompanying drawing, in which:

Fig. 1 is a perspective view illustrating the load and bracing system arrangement in the car; and

Fig. 2 is a plan view showing particularly the center section of the load and illustrating the method of filling-in, bracing and spacing the box stacks opposite the car door opening.

Referring first to Fig. 1, I have diagrammatically illustrated the conventional refrigerator box car as having side walls In, end walls H and a slatted floor structure l2 through which refrigerated air may be circulated upwardly between the transverse rows of the box load l3. As shown in Fig. 2, the car has central side door openings I4, one of which is closed by the door l5 during final center loading of the car through the opposite opening l4 whose door is swung open. When closed, the inner surfaces of the doors are substantially in alinement with the inside surfaces of the side walls 10.

The box load l3 consists of vertical stacks [6 of boxes I! which may be considered placed with their bottoms down and side walls in vertical alinement. Ihe box stacks [6 are alined in rows I8 extending longitudinally of the car, and in spaced rows l9 running transversely of the car. As particularly illustrated in Fig. 1, each end transverse row l9 may be spaced. from the end wall ll of the car by braces extending from the fioor l2 the full height of the stacks l6, and in overlapping relation with the surfaces of adjacent stacks, as shown. At its corners, the end transverse row may be spaced from both the end and side walls of the car by unit brace assemblies, generally indicated at 2|, each comprising a section 22 extending the height of the box stacks and interposed between the end stack and the car end wall ll, section 22 corresponding in thickness to the braces 20. Section 22 is secured to the inner face of a spacer block 23 having right angle surfaces 24 and 25 bearing respectively against the end and side walls of the car. Each block 23 has an angular face 26 to which is secured a second brace piece or section 26a engaging and overlapping the surfaces of all the boxes in the end stack to positively position them in spaced relation to the car side wall.

In loading the car, the end transverse stack row I9 is filled in against the braces 20 and 2|, following which a second set of braces 20a and 21 are put in place. Each brace assembly 21 is similar to the described assembly 23, in that it comprises a pair of vertical sections 28 and 29 secured to the trapezoidal spacer blocks 30. Here the section 28, corresponding in thickness to braces 20a, is received between adjacent transverse rows to space them apart, and section 29, secured to corresponding angular faces of the blocks 30 serves, as before, to positively space end stacks from the car wall. Braces 20a are retained against movement transversely within the load by thin metallic projections 32, a pair of which may be carried by each brace to be inserted between adjacent stacks of the transverse row 19. As illustrated, projections 32 are sufiiciently thin to permit substantial engagement of the vertical stack surfaces between which they are inserted. Accordingly, after the end transverse row H! has been filled in to the car, brace assemblies 21 and their intermediate braces 2011 are put in place preparatory to loading into the car of the sec-- ond transverse stack row [9a. At this point it 4 may be mentioned that braces 20 may carry projections similar to projections 32, for reception between the boxes. Further details concerning the brace arrangement and construction may be had by reference to my Patent 2,585,269 referred to above.

As Fig. 2 will illustrate, the described procedure is followed in filling in the box stacks in spaced transverse rows from opposite ends of the car toward its center opposite the open door, spacers 20a having been inserted progressively between and as the transverse rows are filled in to a center space S centrally opposite the door openings. Thus the load will have been filled in up to this center space, following which a conventional car squeeze (not shown) is moved into the center space to engage and displace the load sections toward the ends of the car, and thus open or widen the center space sufiiciently for its reception of a finally filled-in transverse center row l9b. After completion of the squeezing operation, box stack [6a then is put in place against side spacer assemblies 210. engaged against the closed car door 15. Then intermediate spacers 2019 are positioned as illustrated, with their projections 32a pointed inwardly of the space S, as distinguished from the oppositely pointing projections carried by braces 2011. Box stack Hib then is filled in against the projections 32a and stack ifia, spacers 200 with their inwardly pointing projections are put in place, and so on until the transverse row I9?) is filled out to the door opening 14. Side spacer assemblies indicated by' the dotted lines at 21b are then put in place and the door 15 closed against them to confine the center section of the load.

As will be apparent from the foregoing, the invention permits maintenance of the center section of the load in the same supported and spaced condition as the end sections of the load, thus affording uniformity in the load bracing and spacing throughout the length of the car. Reversal of the braces 2% with relation to the positions of braces 20a permits filling in the center space S, while maintaining the aforesaid uniformity in the load condition.

Since practically all refrigerator cars have standard internal dimensions, and since the boxes used in shipping a particular type of produce also have standard dimensions, the various spacers may be so dimensioned that the entire load exactly fills the standard car. Where a car squeeze is used before filling in the last row of boxes, the action of the squeeze may be so controlled as to leave exactly the right spacing at the center of the car to receive one row of boxes and the associated spacers.
