This invention relates to boxes or crates, and the object of the invention is to providea new construction of box of a light weight material such as plywood or veneer and of such strength and rigidity as to withstand ordinary handling without breakage or deformation.

A further object is to provide a box of such construction as to permit stacking in nested relation when empty whereby they occupy comparatively 10 Small space and in which relationship they are prevented from a wedging relation one with the other. i

A further object and feature of the invention is to provide a box having tapered side and end walls permitting the same to be nested and means provided to limit the extent to which one box may beinserted into the other, and further to'provide, in conjunction with the box, what have termed stacking irons or bails whereby the boxes when filled may be stacked one over the other, the bottom of the upper box resting upon the bail of the lower box, thus providing a space between the bottom of one box and the top walls of the lower box ensuring ventilation, and with the stacking irons so constructed as to prevent lateral displacement of one box relative to the other thereby enabling the filled boxes to be readily transported in such stacked relation.

These and other objects and features of the an invention are hereinafter more'fully described and claimed, and the preferred form of construction of a box embodying my invention is shown in the accompanying drawings in which Fig. 1 is a perspective 'view of the box. Fig. 2 is a vertical longitudinal section of two boxes in superimposed relation.

Fig. 3 is a transgrse section showing two boxes in nested relation.

Fig. 4 is a transverse section of one box and indicating a second box in superimposed relation.

Fig. 5 is an enlarged detail showing theconstruction of the strengthening wires taken on line 5--5 of Fig. 2.

Fig. 6 is an enlarged section of a corner of the box taken on line 6-6 of Fig. 1.

Fig. '7 is a bottom view of the box showing the strengthening wires.

This box is intended for various uses and is particularly adaptable for use in the handling of fruit, groceries etc., and boxes of this character are particularly adaptable for use in'stores to which goods are distributed from a central station and the boxes when empty are returned to the central station. A feature of this inventionis to provide a box that is of tapered form enabling the same to be nested when empty and thus a single wagon may pick up and return to a central point a great many more boxes than is possible with boxes of a form not capable of being nested.

Firstly, therefore the invention seeks to provide a tapered box and, in order to secure light weight,

one made of plywood means being provided to prevent the boxes from becoming wedged together when nested and to enable the same to be stacked in superimposed relation when filled and thus filled boxes will occupy a small amount of space and the tapered box will provide for ventilation for which purpose the bottom of the box at least is provided with apertures. So far as these features of the invention are concerned, the side and end structures of the box may be of imperforate plywood such as is indicated by the end panels in Fig. 1. The box is provided with a top rail 2 extending entirely about the periphery of the box at the top with the corners reinforced by metal angle plates thus covering the upper edge and sides 'of the rails at the corners and the comers of the box are reinforced by the external metal angle 4 and the internal metal angle 5 between the flanges of which the side and end panels are secured. A rectangular frame 6 is provided the bottom '1 of the box which is apertured as at 8 for the purpose of ventilation. The end panels on the interior have a block 9 secured thereto and extending a distance above the bottom to provide a support for the bottom of a nested box as indicated in Fig. 3. The height of this member 9 is just sufiicient to prevent the walls of the nested boxes from becoming wedged together.

When the boxes are filled they may be stacke in storage or in the merchants place of business and the goods maintained open to ventilation by use of the stacking irons or bails 10. These are simply metal rods of a general U form the legs of which enter eyes 11 provided in the side rails 2 of the box and may fold inwardly to the position shown in Fig. 1 in which position the cross portion between the end parts extends transversely of the open top of the box. The irons may be folded outwardly to the position shown in the dotted lines at 1011 in Fig. 2 in which position the cross bar rests on the end rail of the box. When the stacking irons or bails 10 are positioned as shownin Fig. 1, another box may be supported thereon shown in Figs. 2 and 4. This permits ventilation through the space 12 between the bottom of the upper box and thetop of the lower box as will be understood from Figs. 2 and 4. To prevent lateral displacement of the boxes when thus stacked the cross bars of the bails are bent to provide shoulders 13, 13 adjacent each of the side walls of the box forming a loop like portion 14 engaging over the top of the side rails 2 shown in Fig. 1. These shoulders 13 are a distance apart slightly greater than the width of the box bottom and provide a means preventing lateral displacement of the upper box relative to the lower one. This enables the filled and stacked boxes to be transported by shop trucks or the like without the possibility of becoming displaced through jar and shock to which they are subjected in such transportation and further insures the boxes when stacked in a shipping room from accidentally being displaced and thus they are arranged in orderly appearance.

This, irrespective of the specific manner of construction of the side walls except that at least the side walls be tapered for the purpose stated, one of the objects of the invention is attained by use of the tapered wall box and stacking irons ventilation being provided by the apertures in the bottom of the box and the peripheral space 12 about the box at the top.

It is further desirable to secure a box of great strength and light weight. This may be attained by the construction shown in Fig. 1 in which the side walls are formed of slats 15, 15 of plywood which are spaced vertically and, in the said space between slats, a wire 16 is positioned having its ends welded to the metal corner portions 4 and 5 between which the said wire ends and slats are positioned. This arrangement securely ties the box longitudinally. To further strengthen the box utilizing the slat construction, I provide a series of wire loops having the legs 1''! on the inner side of the slats forming one side wall and 18 on the outer side thereof and this'wire 18 terminates in a portion 19 extending part way across the bottom 8 of the box as shown in Fig. '7. The

opposite side wall of the box has a series of loops consisting of the portion 18 on the exterior of the slats and 17' on the interior. The end 19 of the wire 18 of each loop lies in side by side relation on the under side of the box with the end 19 and may be soldered thereto.

It will be noted that these wire ends 19 and 19'. on the under side of the box bottom are above the lower face of the bottom frame 6, this frame being notched to permit'passage of the wires between the frame and the box 5 as will be understood from Figs. 2 and 4. These wire loops 1'7, 18 and 1'7 and 18 may be tied together by wire rings 20 and 21 above and below the longitudinal wires 16 which pass between the loops and also may be soldered at this point thus effectively tying the wires and slats together and providing a light plywood construction capable of withstanding comparatively great strains without distortion.

The side rails 2 heretofore mentioned have a tapered inner face in contact with the side and .end walls and thus a greater width of rail is provided on the under side than at the top. This provides means to enable a person to grasp the of panel like form and stacking irons of U shape having the legs inturned at the free ends for pivotal relation with the respective opposite side walls and adjacent the respective end walls so that in turning the irons inwardly the cross members of the irons are supported by the upper edges of the said side walls to which the irons are pivoted. The cross members of each iron are on opposite sides of a transverse center plane of the box when folded thereover and the legs lie on the outer face'of the side walls to support the side walls from material bulging from the weight of superimposed loaded boxes resting upon the cross members of the iron. Preferably also these irons are depressed or have an offset portion 10 on which a second box may be stacked with the bottom thereof below the upper edge of the lower box whereby material lateral displacement is prevented, the said irons being further turnable to a position clear of the open top to permit the second box to be introduced thereinto in nesting relation.

From the foregoing description it will be evident that the various objects of the invention are attained; that a box is provided that is light in weight, that is readily handled when emptied or filled, and that is adaptable, when filled, to be stacked in superimposed relation and still provide for ventilation which is particularly advantageous when the boxes'are filled with fruit as ventilation prevents sweating of ,the fruit and checks decay.
