12 Claims.

' This invention relates to nesting containers such as boxes formed of wood .or sheet material of various sorts or a combination of both. It has particular reference to the provision of suitable devices for enabling boxes of thischaracter to be stacked either when loaded or in a nested condition when empty.

A feature of the invention is'in the provision of a metal bar or bail pivoted adjacent each of the ends of a box near its upper edge and adapted to be shifted either into a position in which it will permit a series of similar boxes to be stacked, one on the other while loaded, or into a position in which nesting of the boxes will be permitted. The

5 construction is such that when the bars or bails of a series of similar boxes are in the second position, they will cooperate with shoulders near the upper edges of the box next above to hold the boxes of the series in properly spaced relation.

The bails are preferably formed of iron and may be designated stacking irons.

The boxes particularly contemplated by the present invention are of a type embodying a series of rails forming a stiffening frame encircling 2 the top edges of the box and a plurality of runners along the bottom of the box. The stacking irons or balls are pivotally supported by metal reinforcing elements provided at the corners of the vtop frame member and they are adapted to be swung out into the planes of the end walls of the box, having portions at this time resting upon the upper edges of the end top rails. When swung into their other positions the balls have a portion resting upon the longitudinally extending top rails and they then provide suitable seats for the runnersof the box next above so as to prevent lateral movement of one box relative to another.

A further feature of the improved form of stacking iron is its availability as a handle for separating and lifting the boxes whether they are in nested relation or arranged one on top of the other in loaded condition. Furthermore, if the boxes are provided with lids the irons may be utilized to retain the lids on the boxes. Thus the relatively simple, unitary member provided at each end of a box serves a multiplicity of purposes. It constitutes a very inexpensive means of accomplishing the various results specified and at the same time is neat, compact and light, all of which are desirable characteristics.

With these and other features and advantages of the invention in view, one illustrative form of the same 'will'now be described in detail in conjunction with the accompanying drawings, in

or which:

Fig. 1 is a perspective view showing a pair of boxes provided with the present improvements in stacked relation as when loaded.

Fig. 2 is a perspective view of the boxes shown in Fig. 1 but in nested relation.

Fig. 3 is a partial, transverse, sectional view taken through the box adjacent one end along the line 3-3 of Fig. 1.

Fig. 4 is a partial plan view of the box as shown in Fig. 3.

Fig. 5 is a View similar to Fig. 4 but with the stacking iron shown in the other of its positions.

Fig. 6 is a vertical, sectional view of a portion of the box and is taken along the line 6-6 of Fig. 3, and 1 Fig. 7 is a vertical, sectional view taken along the line 7--I of Fig. 5 illustrating a portion of a pair of boxes in nested relation.

It will be understood that the drawings in this case serve to illustrate simply one suitable form of box embodying the present improvements. The box shown is particularly adapted for the shipment of bananasbeing very sturdy and rugged but relatively light. It may be readily used for shipment, loaded in one direction and empty in the other, over a long period of time. Obviously,

the features of the invention are applicable as well to boxes adapted for other uses.

The box may consist primarily of longitudinally extending side walls l0 and end walls II formed of plywood, veneer wood, or laminated boards or fibreboard, or other suitable sheet material commonly employed in the construction of boxes. In order to permit nesting of a group of boxes, the walls are preferably tapered inwardly from the top toward the bottom I2 of the box. The bottom may be formed of any suitable material, which may be either the same as or different from the material employed in the walls of the box. At the four substantially vertical corners, the end walls may be reinforced and held together in any suitable way, as. by the provision of metal angle members l3 which may be nailed, riveted or otherwise secured to the walls. Similar connections and reinforcements may be provided between the walls and the bottom or the.

box as by the use of angle members M. Beneath the lower leg of each of the angle members 14 there is preferably provided a longitudinally extending runner l5, formed of wood, or other suitable material, and adapted to bear the weight of the box and the contents thereof. The corner members It are preferably extended downwardly to a suflicient extent to encompass the outer corners of the runners.

Along the upper edges of the side and end walls of the box there may be provided suitable reinforcing members such as rails It and i1 fitted together at the four corners, as by mitering the ends, to form a rectangular frame. These rails binding the corners of the frame formed by the provided a metal corner .member at each of the joints between the side and end rails. These corner elements may be of any suitable form,

preferably having bent-ovenportions cooperating with the upper and lower edges of the rails II and I1. They may be secured in any suitable way, as by means of nails, staples, rivets or the like.

Coming now to the principal feature of the invention, there is provided at each end of the box a rodor bar suitably bent to form a bail, in

the manner to be presently described in detail,

and adapted to extend from one side of the box to the other across each end. These bails will be referred to as stacking irons, although they perform a variety of functions. as has been pre viously explained. At their extreme ends the stacking irons are provided with inturned portions 2| adapted to be passed through openings 200 in the corner elements 20 at the opposite sides of the box. The ends 21 of the irons also extend into aligned openings I formed in the side rails l8. At substantially right angles to the extensions 2| there are provided arms 22 adapted to swing in a vertical plane through an arc of approximately At substantially right angles to the arms 22 there are provided inwardly extending portions 23 carried at all times in a horizontal position or parallel to the bottom of the box. A short offset portion 24 formed as a continuation of each of the portions 23 extends at substantially a right angle to the latter. When the iron is in the position shown in Fig. 2, the offsets 24 lie in a horizontal plane, while when the iron is shifted into the position shown in Figs. 1 and 3, the oil'sets are disposed substantially vertically. A horizontal portion 25 extends inwardly from the ends of each of the offsets, this portion being in the same horizontal plane as the portion 23 when the iron is in the position of Fig. 2 but being in a lower plane when the iron is in the position of Fig. 3. At the end 28 of each of the portions 26, a right angled bend is provided to form a section 21 which, with the iron in the position of Fig. 2, extends substantially vertically but in the position of Figs. 3 and 4 extends substantially horizontally. right angled bend at the end of each section 21 provides portions 28 which, in the position of Fig. 2, are substantially horizontal and extend outwardly from the end wall of the box, while in the position of Figs. 3 and 4 they extend vertically. Still another right angled bend at the end of each portion 28 serves to provide portions-29 which, in the position of Fig. 2, are substantially vertical and in the position of Figs. 3 and 4 are substantially horizontal. A final right angled bend at the end of each of the portions 29 serves to provide a continuous horizontal portion Another site sides of the iron and thus completes the bail.

the same time the substantially vertically dis-- posed portions 24 and 28 serve to confine the opposite edges of the runners and thus prevent any lateral displacement of the upper box with relation to the lower box. The main horizontal portions III of the irons may at this time cooperate with and provide support for the bottom member I2 of the box above. Now, when the stacking iron is rocked outwardly through an angle of about 90 into the position shown in Figs. 2, 5 and '7, the portions 23 will rest upon the upper edges of the rails I! or the intumed portions of the corner elements 20 to prevent any further movement of the iron. The portions 28, which at this time will be horizontally disposed, serve to cooperate with the shoulders presented by the lower edges of the members I! and thus hold the upper of a pair of nested boxes in a predetermined spaced relation with respect to the lower box. The extent of separation between the undersurface of the rail I] of the upper box and the upper surface of the corresponding rail of the lower box will depend upon the length of the portions 21 of the irons. These portions should be made of sufficient length to provide ample spacing of the nested boxes to permit the insertion'of the fingers between the adjacent Due to the vertical disposition of the portions 21 when the boxes are nested, there will be little or no tendency to distort the irons by virtue of the weight of the upper boxes resting upon the irons. Various other features and advantages of the construction disclosed herein will be apparent to those skilled in the art. While one admirable illustrative form of the invention has been disclosed in considerable detail, it will be understood that various features of the construction may be modified without departing from the general spirit and scope of the invention.
