it PALLET OR S FOR LIFTING TCKS AND THE LI Dewey H. lBitney, Steel Products poration of Michigan Albion, Mich, assignor to Union Company, Albion, Micln, a cor- Appiication June 5, 1947, Serial No. 752,750 12 Claims. (Cl. 248-120) This invention relates to improvements in material handlingpallets r skids for lifting trucks and the like.

The main objects of this invention are:

First, to provide a material handling pallet or skid for lifting trucks and the like which is light in weight and at the same time very strong and rigid and capable of supporting and carrying heavy loads.

Second, to provide a pallet or skid of the character described fabricated entirely of metal.

Third, to provide a pallet or skid which may be engaged by the forks of a lifting truck when the forks are presented from any one of the four sides of the pallet or skid or cornerwise thereof.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is iilustrated in the accompanying drawing, in which:

Fig. 1 is an inverted plan view of a mate- I rials handling pallet or skid embodying the invention, a portion of the grid-like top or platform being illustrated.

Fig. 2 is an enlarged fragmentary view in vertical section on a line corresponding to the broken line i--2 of Fig. i.

Fig. 3 is a fragmentary enlarged perspective view of one corner of the pallet or skid.

Fig. t is a fragmentary perspective view of an intermediate portion of the pallet or skid.

Fig. 5 is a fragmentary perspective view partially in section on line 5-5 of Fig. 2.

in the embodiment of the invention illustrated, the grid-like top or platform designated generally by the numeral 6 comprises an upper series of parallel wire or light rod slats 2 and a lower series of parallel wire or light rod slats 3 arranged in crossing relation to the upper series and welded thereto at the crossing point as conventionally indicated at i, the other weld connections not being illustrated.

Tie rods or reinforcing rods it are arranged on the under sides of the under series of slats adjacent their outer ends and welded thereto as indicated at t. This rod serves the double purpose of supporting the under series of slats and as means for attachment of the base legs there= to as will be hereinafter described.

The base comprises outer base bars l and 3 and intermediate base bars 9 and it. The outer base bars 71 and t are disposed withtheir meeting ends in lapping relation, the bars 3 in the embodiment illustrated being superimposed on the bars l and the superimposed portions bein upwardly oflset as indicated at ii. The superimposed parts are welded together as indicated at M in Fig. 5, all of the welds, however, not being indicated in the drawing.

The bars I have upturned leg portions 63 at their ends while the bars 8 have upturned leg portions it at their ends, the adjacent edges of these leg portions being welded together at It. The legs it of the outer bar l are welded to the inner sides of the rods 5 as indicated at it, while the legs M of the outer bar 8 are welded to the end slats of the lower series as indicated at illsee Fig. 3.

The intermediate bar 9 has upturned legs It welded at their ends to the inner sides of the tie rods 5, as indicated at It in Fig. 2.

The intermediate bar I0 has upturned legs 2t arranged on the inner sides of the outer slats of the lower series and welded thereto as indicated at 2!. The intermediate bar it is upset centrally at its ends to overlap the intermediate bar 9 and the outer bars l.

Supplemental leg members 22 are provided, these havingangularly disposed bottom portions 23 superimposed on and welded to the bar in as indicated at it. These supplemental legs 22 di verge upwardly from the leg 28 and have their upper ends welded to the adjacent slats of the lower series as indicated at 25 in Fig. i.

The center of the deck is supported by the U-shaped leg member 25 disposed with its bight ii on the bar it and welded thereto as indicated at 28 in Fig. 2. The upwardly diverging legs 29 of this center leg unit are welded to'the adjacent slats oi the under series as indicated at 30, Fig. 2.

The bars are longitudinally corrugated or have longitudinal reinforcing ribs it while the legs have longitudinal reinforcing ribs 32. This results in a rigid structure even when the parts are formed of relatively light stock. It will be appreciated that in handling various materials strength combined with lightness is a highly important factor and I have produced such a combination.

I have illustrated and described the invention in an embodiment which I consider highly practical. I have not attempted to illustrate or describe various adaptations thereof which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt the invention as may be desired. The grid type of platform is especially desirable in the agcombination illustrated but a sheet metal top or 3 platform or even a wood top or platform might be employed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
