10 Claims. 1

My invention has for one of its objects the provision of a pallet for use in storing and transporting articles and which can readily be stacked in either a loaded or unloaded condition, and which can conveniently be handled by trucks of the ordinary fork-lift typ my pallet being of lighter weight for a given load sustaining load capacity than various types of pallets heretofore used.

Another object of my invention is to provide a pallet structure which, except for the deck sheet, may readily be formed of a single sheet of welded wire mesh or the like.

Another object of my invention is to provide a pallet wherein legs which are relatively spaced have extended footing areas, and, at their upper ends, are provided with means for supporting and retaining in .place a deck sheet thereon, in an improved manner.

Still another object of my invention is to provide an improved method of making pallets of the character referred to.

In the accompanying drawings, Figure 1 is a plan view of a completed pallet made according to my invention; Fig. 2 is an edge view thereof; Fig. 3 is a plan view showing a mat of welded wires or rods previous to the bending of certain members thereof into position to support a deck sheet; Fig. 4 is a view taken on the line IV-IV of Fig. 3; Fig. 5 is a plan view of the mat frame in its completed form, with the deck sheet omitted; Fig. 6 is an end view of the structure of Fig. 5; Fig. 7 is a side view of the structure of Fig. 5, but showing a portion of the mat frame only partly bent to its completed position, previous to the insertion of the deck plate; Fig. 8 is an enlarged view of a corner structure of a completed pallet; Fig. 9 is a' fragmentary plan view thereof, Fig. 10 is a sectional view taken on the line X--X of Fig. 1, but with some small modification, Fig. 11 shows a plan view of a modified form of pallet embodying my invention; Fig. 12 is a plan view of a mesh sheet used in forming a footing and supporting framework for a deck sheet; Fig. 13 is an edge view of the mat of Fig. 12; Fig. 14 is a plan view showing the sheet of Fig. 1, with portions thereof bent upwardly in position to receive a deck sheet; Fig. 15 is an end view of the structure of Fig. 14; Fig. 16 is a side view thereof; Fig. 17 is an enlarged side view of a portion of the pallet at one corner thereof; Fig. 18 is an end elevational view thereof at one corner of the pallet, and Figs. 19 and 20 are respectively fragmentary side elevational and end elevational views of the pallet.

The base or supporting frame 3 for a deck sheet or pallet plate 8 is formed from a single sheet formed from wire or light rods welded together, as by automatic fabric-welding machines of various well known forms, the wires being assembled in sheet form and then bent to a shape that will support .the deck sheet in elevated position, so that the forks of a lifting truck can be moved into the pallet, beneath the deck sheet, for transporting or stacking.

The mesh sheet as shown in Figs. 3 and 4 comprises a series of transversely-extending wires in and II that overlie and are welded to longitudinally-extending wires i2 and i3, this overlying arrangement being shown more clearly in Fig. 4. A second series of wires variously designated as H, l5, l8, l1, l8, I9, 20, 2| and 22 are placed onthe wires l2 and I3, in the same plane as the wires ill-ll and are welded to certain of the wires i2 and i3 at the points marked as, the

circles at certain points of intersection being employed to indicate the crossings at which these wires It to 22 are not welded.

A series of wires respectively numbered 24, 25, 26 and 21 overlie and are welded at their points of intersection to the wires H to 22 but are not welded to ill and Ii. Pairs of wires 2829 and 3ll3l overlie and are welded to the outermost extremities of the wires i4-i5-i6 and 20 2 l22 respectively as well as to the wires i I. The

wires

23 and 29 are spaced apart slightly to serve as a groove for receiving an edge of a pallet plate when the mesh has been bent to form, and the same is true of the wires 3ll3l. Similarly, wires 33 and 34 are welded in spaced-apart relation to the wires l3 at one end of the mesh sheet and spaced-

apart wires

35 and 36 are welded to the opposite ends of these wires i3 so that when the end portions of the mesh sheet are bent up, the endmost edges of the pallet deck will be received into the spaces between these wires.

Upon completion of a mat as shown in Fig. 3, those portions of the wires H, M, ii and I6 that extend beyond the wire [3 at one edge are bent upwardly to the position shown more clearly in Fig. 6. Similarly, at the opposite edge of the mat, the wires l i, 20, 2| and 22 are bent upwardly. Thereupon, those portions of the wires I: that extend beyond one end of the mat and which carry the wires 33-34 are bent upwardly, and

the adjacent ends of the

wires

33 and 33 at one corner of the mat are welded together as shown at 33 in Fig. 5. Also the

wires

28 and 33 are welded together at 39.

Also those portions of the wires i4, i5 and it that extend between and are welded to the wire 23 and the adjacent wire l3 arebent upwardly about ing the wire 21 to the plane of the wire :4, so that it can be welded to the wire 24 and thus assist in supporting the deck sheet.

Also both ends of each of the wires, l1, l and II that are respectively welded to the

wires

25 and 25 are bent upwardly from the base wires l0 and I I, thus raising the

wires

25 and 25 into position that they can be welded to the wire 34 and thus serve to assist in supporting the deck sheet. To stiffen the upper portion of the framework, rods 40 which extend the full width of the structure are welded to the sides of the leg elements and to the undersides of the

wires

24, 25, 25, 21, 28 and 2 l as shown more clearly in Fig. 2. Where still greater bracing strength is required for the upper ends of the legs, and greater vertical support for the deck sheet is required, additional tie rods (Fig. and welded to the sides of leg elements such as l 4l5l6; I1ll-l9 and 2l22.

The deck sheet 2 may now be slid into place in the groove-like spaces formed by the wires 28- 29, -21 and 2H4. Thereupon, the other end of the mesh sheet, which carries the wires -35, will be bent upwardly to bring the ends of the wire 25 into engagement with the ends of the wires 29 and 30 and welded connection of these wires effected at 42, the wire 25 being welded tothe adiacent ends of the wires 24--252521.

The bending of certain portions of the mesh sheet to generally channel form not only provides adequate support for the deck sheet at various points throughout its undersurface, but gives a truss-like or girdle-like effect to the pallet frame, and nevertheless, the forks of a lifting truck can enter into the frame from eight different directions.

The wires or rods entering into the mesh structure will be of gauges adequate for the strength desired. For example, in a pallet about 32 inch by 40 inch and having a depth of about 4 inches, the wires may mainly be 2-gauge (V inch), although for greater strength, I prefer to make the shorter wires or rods l4 to 22 inclusive of 0- gauge.

The decksheet 5 may be of any suitable material such as expanded metal, ply wood, and sheet metal inwhich later case, it may contain a sumclent number of perforations to reduce its weight without seriously weakening it. Where a sheet having a fairly flat surface is used, such as ply are bent downwardly to a common plane with the wires 44. The

wires

44 and 45, near their ends, are welded to the underside of a marginal member 45 which may be formed of a single rod or formed of four rods welded together.

The framework for supporting the deck sheet' is tormed from a mat shown in plan view in Fig. 12, the members of the mat where they cross being welded together except at those crossings marked 0. The mat comprises

wires

41, 45 and 45 that extend longitudinally for some distance beyond the body portion of the mat, so that their extremities may be bent up to form legs or supports for the deck. Four short wires also extend beyond the body portion of the mat, so that their extensions can be bent up. Wires 51 are approximately coextensive in length with the finished pallet.

Wires 52 extend crosswise of the pallet, the full width thereof in overlying relation with the longitudinal wires. Yoke-shaped

elements

52, 54, 55, 55, 51 and 58 are welded at points z where they cross other wires, but are not welded at thepoints of intersection or crossing marked 0, so that they may be bent up to form deck supports. Short wires 59 are provided near each corner of the mat and other wires 50 and GI at points between certain of the comers. These elements also can be bent upwardly, to U-form, to assist in supporting the deck sheet, since they are not welded at their crossings which are marked by 0,

Short tie rods

52 and 53 underlie and are welded to certain of the longitudinally-extending wires, tostiifen and brace the same.

When a sheet has been formed to the contours shown in Fig. 12, which can suitably be 'done ,on an automatic electrical welding machine, the various supporting

elements

41, 48, 48, 50, 53, 54, 55, 55, 51, 55, 59, 50 and 51 have their extremities bent upwardly to form legs or supporting elements, as shown more clearly in Figs. 15 and 16. The framework thus formed will then be welded to the deck sheet of Fig. 11, the upper portions of wood or sheet metal, the top surface of the sheet may be coated with a tacky material such as one of the well known non-hardenable adhesives. When packages are placed on such a surface, rope lashings are not required, because the packages.

will be adequately held by the adhesive during handling and transportation, and can, nevertheless, be removed therefrom by the application of a force which is not great enough to damage the sheet having longitudinally-extending. rods 44 -that' are overlaid by and are welded to trans- 7y versely-extending rods 45. The ends of the wires deck sheet near these leg elements being variously welded to the marginal rods 46 of the deck sheet and to certain of the other wires in the deck sheet. Additional strength is provided by welding heavier longitudinally-extending rods 54 and transverselyextending rods 85 to the sides of the legs and to under surfaces of the deck mesh, at suitable spacings or intervals for the required strength.
