Figure 13 is a view similar to Figure 12, illustrat- 20-20, one on each side and constituting bottomsills, four vertically extending angle corner posts 2l-2l; Z-bar end plates 22 and Z-bar side plates 23.

The frame elements just referred to are securely united together as follows. The four base angles or sills 20 are connected at the four corners of the container by four corner castings 24-24 each of which, as best shown in'Figures 1, 2, 6, and 7, is of right angular, horizontal section with two vertical webs25 and 26 riveted at their lower edges, as indicatedat 21-21, to the respective side and end base angles 20. Said webs 25 and 26 are also riveted to the respective flanges of the corner angles, as indicated at 28-28, thus providing a rigid construction at the lower 'corners of the shell. Said castings 24 also provide the mountings for the attaching bolts hereinafter referred to.-

At the upper'corners, the side and end Z-bar plates and the corner posts are secured together by other castings 29-29, the details of which are best illustrated in Figures 1, 3, and 4. As clear from the drawings, each of the side and end 2- bar plates is arranged with the web 30 thereof disposed horizontally, the inner flange 3| extending vertically upward and the outer flange 32 extending vertically downward. Each of the corner castings 29 is conformed to the Z-bar plates, as clearly shown in Figures 3 and 4 and also to the slopeor pitch of the side plates, as

shown, said castings being riveted both to the vertical flanges 3| of the Z-bars, as indicated at 33-33 and to the depending flanges 32, as-indicated at 34-34. Each of said castings, 29 is also provided with a depending right angular corner section conforming to the angular corner post 2| and to which the latter are riveted, as indicated at 35-35. The corner castings 29 are each formed with an upstanding lifting hook 36 to permit of the attachment of a sling and the handling of a container by a crane in the usual manner.

The side and end walls of the shell are all what may be termed solid or fully closed, that is, there are no doors or other openings so that the walls of the shell are absolutely weather proof. Each of the side and end walls preferably comprises two sheet metal panels 31-31 integrally strengthened or rigidifled by a plurality of vertically extending corrugations 38-38. Each of said panels is riveted along its bottom edge, as indicated at 39-39, to the vertically extending flange of the respective base angles 20, and on the outer sides of the latter. At their upper ends, each of the panels 31 is riveted to the inner side of the depending flange 32 of the corresponding 2- bar side and end plates, as indicated at 40-40. In this connection, it will be understood that the panels for the ends, as shown in Figure 2, are square across the top, whereas the panels for the sides, as shown in Figure 1, slant to conform to the roof pitch. Along their vertical edges, each of the panels has its margin riveted to the inner face of the corresponding flange of the corner post, as indicated'at 4l-4l and it will also be seen from inspection of Figures 3, 4, 5, 6,.

and 7 that certain of the rivets for securing the corner castings 24 and 29 to the frame elements are also utilized in securing the panel sheets to the respective frame elements. In order to properly rigidify the side and end walls along their vertical median lines, a special joint is there employed as best illustrated in Figure 7. As there shown, the vertical joints between each pair of panels is obtained by using an inner plate 42 and an outer plate 43, said plates 42 and 43 along each set of vertical edges being riveted to the interposed edge of the corresponding panel by a vertical series of rivets 44-44. The outer plate 43 of each joint is vertically outwardly corrugated so that a tube-like post is formed which affords great strength against collapse, buckling or bending in any direction, it being understood that the upper and lower ends of each said post joint construction is secured to the corresponding side or end plate and base angle 20.

The roof is completed preferably by a single sheet of metal having the desired roof pitch incorporated therein, the marginal edges of the roof sheet being bent downwardly along all four edges and riveted to the upstanding of the Z-bars, as indicated at 45-45.

The inner cage'or retainer for the/merchandise consists essentially of a suitable base or platform of proper strength to sustain the weight of the merchandise, and a very light, more or less skeletonized superstructure, which latter may vary in detail as hereinafter indicated. The base or platform of the inner cage preferably comprises two side angles 46-46, two end angles 41-41, four corner castings 48-48, cross channels 49-49 and suitable supporting angles and braces hereinafter referred to. Each of the base angles 46 and 41 is arranged with its lower narrow flange 50 disposed horizontally and adapted to rest on the floor or other support and with its longer flange 5| extending vertically, the bottom flange 50 being extended outwardly for the purpose hereinafter described. Said angles 43 and 41 are four in number and uniformly spaced, extend from side angle 46 to side angle 46 and are united to the latter by suitable corner angles 54-54, the

lower flanges of the channels 49 being in the same plane as the flanges 50 of the base angles 45 and 41 so as to obtain a uniform support throughout the area of the bottom of the cage.

The floor of the base is preferably provided by a metal sheet conforming to the area of the platform structure and supported around its edges by suitable angles 56 and 51 secured to the base angles 46 and 41 respectively. On top of the sheet 55 are placed the wood planks 58-58, which may be secured in place by suitable wood screws passed upwardly through the metal sheet 55. In this connection, it will be noted that the top surface of the planking is flush with the top edges of the base angles 46 and 41. By thus, in effect, inserting the planking within the base frame flush with the upper edges of the base angles, the latter effectively protect the edges of the wood flooring against splintering or chipping oif, which might otherwise possibly occur from trucking the goods or when the shell is lowered over the cage.

As shown, each of the corner castings 48 is provided at its outer corner with an upstanding angle-shaped spud or projection 59 to which the superstructure frame elements are secured. Preferably, the superstructure frame elements are two in number, each in the farm of an angle bar 60 having two vertical sections 6! united at their tops by inclined sections 62 and 63 to just clear the end Z-bar plates 22 and to conform tothe pitch of the roof, as best shown in Figure 12. These two members 60, which together provide the four corners of the inner cage superstructure frame, may be anchored to the spuds 59 either permanently by riveting or by bolts, as indicated at 64Ehl. Where bolts are used, it is obvious that the superstructure may be removed and interchanged with others of somewhat different form so as to afford greater range in the handling of different kinds of merchandise. In the form of inner cage shown in Figure 12, only the sides thereof are provided with retainer walls which, in the form shown, may consist of heavy wire cloth suitably riveted to the frame elements 6|]. With this construction, it is evident that the two ends of the cage are fully open and available for the loading and unloading of the merchandise within the cage. For other classes of merchandise, the cage maybe modified, as for instance shown in Figure 13, where a plurality of horizontal shelves or partitions 6565 are employed, the same being supported at their ends and sides by suitable angles 66 riveted to the frame elements 60. In this construction, a roof sheet 61 may also be employed if desired to ob tain somewhat greater rigidity for the superstructure. Any suitable devices may be employed at the open ends of the cage to help retain the loading in place, which devices may be in the form of removable or hinged gates or bars which I have not deemed it necessary to illustrate.

Referring particularly to Figures 12 and 13, it

will be noted that the base angles 20 of the outer shell are all in the same plane with the lower flanges thereof extended outwardly and horizontally, so that the same are adapted to rest firmly with full surface contact on the corresponding out-turned, horizontal flanges 50 of the base angles 46 and 41 of the inner cage, thus providing a weather seal between the inner and outer members of the container. It will also be observed that the level of the floor of the cage is disposed several inches above the bottom edges of the outer shell, thus further minimizing any tendcontents while in transit.

When the shell and cage are assembled in telescopic relation, they are adapted to be firmly secured together by the following means, particular attention being directed to Figures 2, 5, 6, and 8. Each of the corner castings 48 of the cage is provided with a pair of heavy, horizontally, outwardly extended lugs 68, which are accommodated in corresponding recesses 69-69 in the corner castings 24 of the shell when the latter is placed over the cage. Each of said corner .castings 24 is formed with an offset rounded web 10 providing, at its ends, partial bearings 'H'H for the cylindrical ends 12-12 of a swinging T-bolt T3, the depending threaded shank of which is adapted to be entered between the corresponding pair of lugs 68 and the parts then rigidly secured together under any desired tension by means of a nut 14 engaging the undersides of the lugs 68. By loosening the nuts 14, it is obvious that the T-bolts 13 may be swung laterally outward, sufiicient to clear the lugs 58 and the shell then removed by a crane. With the parts locked or latched together, as shown best in Figures 2 and 5, it is evident that the two parts may be handled as aflunit in moving onto and off of the car equipment or elsewhere and that by releasing the T-bolts the shell may be removed and the cage with its lading then handled separately and placed on a truck for delivery.

With the form of container hereinbefore described, it is evident that the outer shells which are the heavy strength and weather-protecting members, need not be used in handling the freight between the warehouse and the places of business of consignor and consignee, so that greater pay loads may be handled by a truck and the loading and unloading of the cages done with maximum ease. Further, when the shell and cage are assembled and latched together for shipment on the railway equipment or otherwise, there is no possibility of damage to the goods from the elements, nor is there any possibility of theft, since the only way access to the lading can be obtained is by removing the outer shell, which on account of its weight, requires a crane. With my improvements, the use of all doors and corresponding expensive door operators may be entirely eliminated; the amount of equipment for handling a given volume of business may be materially reduced; and a greater range is obtained in the handling of small quantitles or assorted materials without having to miir the same in transporting from station to station.

While I have herein described my improvements more particularly with reference to rail- 'ency of rain or the like to reach any of the the like. It is further to be understood that the terms railway car type or railway type used be apparent to those skilled in the art, certain novel features of my construction, particularly of the outer shell, may be used to advantage in containers other than of the telescope type and the claims are intended to include all such other types except as they may be otherwise limited. All changes and modifications are'contemplated that come within the scope of the claims appended hereto.
