"the present invention is more especially concerned, embodies therein a pallet'that includes a platform preferably of paper board, having'rows ofidepending supporting members on its bottom and adaptedto' support a commodity load, the

load and the pallet being secured together as 'a shipping structure by meansjof tensioned members in the'form of metallic straps or'b'andsthat pass over the top of the load, down opposite sides thereof and then across the bo-ttoinbf the platform 'of the pallet."

A structure of this kind is illustrated and described in my copending application Serial No.

71,234, filed January 17, 1949,

One of the objects of the present invention is to provide a palletized shipping structure, which has greater strength and resistance to damage, and which may be produced at a saving in time and material in fabricating the structure.

Another object of the invention is to provide a structure of this 'kind, so made that the tensioned members which secure the load and the pallet together may be drawn up tighter and placed under as well as others, together with'the advantages thereof will more fully appear as the specification proceeds.

In 'general'the improved palletized shipping *structure serves the purpose of the well known f tote boxes, in which for example,'suppliers of parts ship them'from the point of manufacture to the place of assembly. Such boxes, as before mentioned; are usually made of Wood, are expensive to produ'ca-andheavy to handle.

The improved structure has many advantages over such'tote boxes, especially as to cost and ease of handling. As a whole, it embodies a pallet that includes a platform having means, such as rows of spaced members, on its underside, to support the platformabovethe floor in a manner providing passages under the platform for receiving the arms of a lift truck and by which the-structure may be transported locally. In one instance, these rows of spaced supporting membersare so formed that the members in each row may be operatively engaged and connected by a stiffener bar, with which a part of one of the tensioned members, that secure the load and the pallet together as a'structure, is engaged and whereby greatertension may be imposed upon the tension members without crushing the platform of "the pallet and drawing the same out of its intended Iflat condition. In'another instance, the supporting member'sin each row are so'formed' at the bottom as tobe directly engaged and to'confine, against lateral movement and displacementya In each instance, however,,the force of the tensioned members is transmitted to the platform of the each row of "platform supporting "members for pallet 'thro'ugh'the supportingmenib'ers. Thus removing such applied force from these parts of the platform between such supporting members and which acted to distort and warp the same.

Referring now in detail to that embodiment of the invention illustrated in Figs. 1 to ,4 inclusive of the accompanying drawings, the improved palletized shipping structure comprises a pallet I0, I

a commodity load I I supported on the pallet and a plurality of tensioned members or bands 12, by which the load and the pallet are secured together as a unitary structure for convenient handling by a conventional lift truck.

The pallet includes a rectangular platform [3 7 preferably made of paper board stock, which is provided along its four margins with flange extensions foldable into an upright position along suitable fold lines, by which said extensions are connected or joined to the platform, as best appears in Fig. 2. On the underside of this platform are sets of'sp-aced supports 15, arranged as right angled rows, thus leaving spaces between said rows of supports. Preferably the supports are in the form of short, rigid tubular pieces of paper board, secured to the bottom of. the platform in any suitable manner. In opposite sides of each member l5, about midway between the top and bottom ends thereof, are openings 16 which, 'as

best shown in Fig. 3, may have a rectangular shape. The supports I5 in each row, in one direction of the pallet, are arranged with the openings I5 therein, in line with oneanother as appears in Fig. 2.

The commodity load II is shown in Fig. 1 as enclosed in a paper board carton having a bottom size substantially the same as that of the platform l3 within its flanges l4 and of a height 4 band at said other side of the carton. By means of a conventional tool (not shown) the band ends are drawn toward each other and tensioned and then saidends are secured together by means of a conventional c1ip24, as appears in Fig. 1.

In Fig. 5 a modified form of palletized package structure is shown wherein a carton is not required when certain items are being packed for shipment. In said figure the pallet is of the same construction as that described in connection with respect to Figs. 1 to 4 inclusive with the exception that in the platform l3, in line with the upper end of the supports l5, are suitable openings.

The items 31 shown therein are, for illustrative purposes, in the form of metallic shells used in automobiles. Each includes an annular body 42 open at its upper end and having a central extension 33 of reduced diameter projecting from the bottom thereof.

In making up a palletized shipping structure :of said items 3| in connection with a pallet, a layerof such items is disposed upon the platform,

with the extension 33 of each item thereof extending through a hole in the platform to project into the top end of a support I5, the bottom of the body 42 of the item 3| resting flatwise upon the platform about said holes. A separator sheet 34 preferably of relatively heavy paper board is disposed upon the top edge of the bodies of all of the items constituting the first layer upon the platform, which separator has holes therein arranged to line up with the holes in the platform.

A second layer of items is then disposed upon the first or bottommost separator sheet, with the extensions 33 of said items extending down through the holes in said separator sheets. Thereafter other tiers are built upon the first one to the desired height. A separator sheet is preferably provided at the top.

A set of stiffening cleats 35 of Wood or other suitable material is disposed upon the top separatorsheet to extend in one direction thereof,

supports 15 as shown, so that there is one under each stack of articles. 7

When the carton has been loaded with the items 21, the cover partsare folded down to form the top 18 for the carton.

, The loaded carton, disposed upon the platform, is thereafter secured thereto as follows:

A stiff elongated beam-like bar 22, which is preferably of a channel bar cross section and of a length approximating the width of the platform l3 of the pallet,'is inserted through the aligned openings [6 in a row of supports I5. The" bar is inserted so that the flanges extend downwardly from its web, which is engaged flatwise against the upper ends or edges of the openings 16.

A cleat or bar 23 of wood or other suitablematerial is thereafter disposed transversely upon the top of the carton, one in line with each row of supports l5 having the aligned openings therethrough.

Thereafter metallic bands l2, before mentioned, are applied to hold the loaded carton upon the pallet so as to coact therewith in forming the improved shipping structure. A portion of each band is inserted through an associated bar 22. and another portion thereof is passed up along one side of the carton, then longitudinally of a cleat 23 and then down the other side of the carton for attachment to the other end .of the and then a second set of stiffening cleats 36 is disposed upon the first one to extend at a right angle thereto. The cleats 36 are disposed in line with each row of supports l5 in which the aligned openings are provided.

Metallic :bands l2, as before, are disposed in surrounding relation upon the thus far built up structure, with a portion of each band passing through a bar 22, and with another portion extending longitudinally of a cleat 36. When the ends of said bands are drawn together so that said bands are placed under tension, the ends of each band are clipped together. It is to be noted that the items also provide vertical stacks that are indeed rigid and which are securely held together by means of the tensioned bands.

Figs. 6, 7 and 8 illustrate a modified form of supporting member which may be advantageously used, as a part of the pallet in the structure, and which member is indicated by the numeral [5a. This member depends from the bottom of the platform, as before, but instead offhaving the aligned openings IS in its opposite sides, it is formed in opposite sides of its bottom margins with downwardly opening recesses [6a, which are of a depth greater than the thickness of the bands l2 and the member 22 used therewith. When the band is in place upon the structure, portions of each band extend through aligned recesses lBa in a row of supports l5, the band surrounding the remaining portion of the structure and being tensioned. When said portions function of the holes afforded, which withstands of the bands are disposed in the aligned recesses 16a in each row of supports 15a, said portions are disposed above the plane of the bottoms of said supports but well below the bottom of the pallet platform.

One of the advantages of the arrangement illustrated in Figs. 6, 7 and 8 over the form shown in Figs. 1, 2, 3 and 5 is that there is greater space between the bottom of the pallet platform and the top of bar .22. It is thus possible to provide sufficient space to accommodate the arms of a lift truck as indicated by the dotted lines F, without unduly increasing the height of the supports. In this Way it becomes possible to insert the arms F from any of the four sides of the pallet.

In Fig. 11 there is illustrated a construction in which certain of the supporting members l5d are arranged so that a portion of the outer surface thereof terminates in a plane coincident with the outer sides of the adjacent pallet base portion. In Fig. 11 the recesses l6a or IE as the case may be are in the bottom but they may be centrally disposed as in Figs. 3 and 9 if desired. In any event it is not so necessary to use the bar 22 because the .force of the pull, when tensioning band or bands I2, is taken by the relatively rigid strong support member and not by the much more easily deformable base portion of the pallet which would be the case were the support member not so located and truck, one of which is shown in dotted lines, may

be accommodated in the space between the base portion of the pallet and the top of the tension band when the recesses are at or close to the bottom of the support.

The supporting members l and 15a, before mentioned, are tubular in form and preferably made of heavy paper board. However, certain of the advantages of the invention may be had by the use of solid or non-tubular constructions, such as shown in Figs. 9 and 10. In Fig. 9 the support is indicated at l5b, which may be made of wood or other suitable material having a hole I6b extending laterally therethrough to serve the 16 in the construction previously described. In Fig. the support is indicated at I50, which may also be made of wood or other suitable material, and has a recess or groove I 60 extending across its bottom to serve the function of the recesses I611. before mentioned.

With the parts made and arranged, as before described, a good strong shipping structure is heavy crushing strainswithout damage.

While in describing the invention I have referred in detail to the form,'construction and arrangement of the parts involved, the same is to be considered only in the illustrative sense and therefore I do not wish to be limited thereto except as may be specifically set forth in the appended claims.
