It will be understood that, in the specification.

and; claims he t rms --side and ends are used for convenience in description and desig: hating the parts although the invention may be embodied in receptacles or bOXBSOf square shape,

- 'ilhe embodiment of. he in en ion illus ate 2 comprises, a bottom I, side walls 2, 2 and end wails. 3, these, being preferably of thin panel stoolr. They may be of fiberboard or of veneer material One of the advantages of the ,inven v tion is tha relatively thin bottom and wall stock m y be used.

The side horizontal members 4 are of angle section disposed facing upwardly and inwardly. Theymay be formed of sheet metal of suitable. gauge, The bottom legs 5 are secured to the, bottom by the fasteners 6, desirably by rivets when the box is permanently assembled.

The side walls 2 are secured to the vertical legs of the side horizontal members by the fas:

tenors 1,. The vertical legs 4 of the side hori;

zontal members are cut away at 8 for a purpose which will appear as the description proceeds. The end horizontal members 9 are also of angle section and are disposedfacing upwardly and inwardly and are provided with angularlydis-; posed arms ID at the ends thereof. The horizontal legs of the end members have angular slots like openings H at the corners thereof.

The end walls are secured to the. vertical legs of the horizontal end members by fasteners "I conventionally illustrated. It will be understood that the legs of these horizontal members are provided with holes l2 to receive the fastenings 1.

The horizontal legs of the end horizontal mem.-. her arms are lapped upon the horizontal legs of the side members and secured thereto, the ver-z tical legs being secured to the side walls by. fas eners The Vertical legs of the side horizontal menu.

bars are cut away at theends so that the vertical less of he arms a li cl s a ainst the si e wa ls.

The angled corner uprights [3 are lapped upon the. ad acent.- ends. o t e s de and, end W s nd are p o ided w h holes 14 receivin the fas eners These fasteners are shown onventi na l wi h the e cept on of the enlar d. i s o Fi s. 3 and a. Tl-losev corner uprights are disposed through the slot-like openings H in the end hori-i. zontal members and they are provided at their lower ends with runner supporting foot portions designated enera y b t e n m a 5, t ese ddt: or ons of th r nne s p s. e ns f rmed" b fol n h bo tom port ons l6 a d ll of t ess of the cornerupr ehts nt sup r mposed rela ion as. clearl liliesz i. dead it These. foot portions have holes adapted o. receive. the rive s 19 which are arran ed throu h the. 20 arr n ed on toot portions. as is clearly. shown Figs 2 and a;

18 therein These runners have reduced end portions 2| engaging the supports. The runners are arranged below the horizontal legs of the angled horizontal side members and secured thereto as by the fasteners 22.

The side and end rim members 23 and 24 are arranged on the outer sides of the wall panels and secured thereto as by the rivets indicated at 25; The ends of these rim members overlap the corner uprights.

Top corner irons 26 are provided, these being angled to embrace the ends of the side and end rim members and are preferably provided with top and bottom flanges 21 and 28 which engage the tops and bottom edges of the rim members.

The pintle bearings 29 are arranged through openings 38 formed in the arms of the corner irons, there being outward offsets 3i surrounding the openings to receive the retaining flanges 32 or the bearing members.

The stacking bails or irons 33are provided with arms 34 having inturned bearing engaging pintles 35 at the ends thereof so that the stacking irons or bails are pivotally supported to swing across the top of the box as shown in Fig. 1 or to depend at the end of the box. When in erected position they engage the top flanges of the corner irons. This distributes the load on the stacking irons to the side and end rim members and the supporting walls and the corner irons also serve as wear members protecting the walls and rim members. By arranging the corner uprights through the horizontal connecting and reinforcing members the load and stresses are well distributed and also projecting vertical edges at the corner eliminated at the point where they would be likely to engage in handling and dragging the box on its runners.

Structures embodying the invention are very strong and rigid in proportion to the weight of the stock employed and are capable of carrying heavy loads. The invention has been illustrated and described in a highly practical embodiment thereof Certain other embodiments and adaptations have not been illustrated or described which are contemplated as it is believed that this disclosure will enable those skilled in the art to embody or adapt the invention as may be desired.

Having thus described our invention, what we claim asnew and desire to secure by Letters Patent, is:
