My invention relates packaging flat rolled sheet material for handling 1 and. shipment. and inparticular to a skidformed. -=-=from sheet metal.

At-present woodskidsare-used for the above pur;pose, generally two 4x 4 timbers ofabout -the-same length as-the sheet material to be packaged. --The timbers: are placed in spaced -apart parallelrelationship; the sheets ipiled thereon-and the package .boundtogether by? sev eral-steel straps or--wires passed around the bundle in both longitudinal and transverse directions. A large stock of timbers must be kept for this purpose. The weight and variety of sizes involved makes it uneconomical to return wood skids to the shipper for re-use. The procedure is wasteful, moreover diiilculties are often encountered in handling the packages at their destination due to shifting of the skids during loading and shipment.

It is an object of the present invention to provide a relatively small sheet metal skid which may be used in multiples as required by the length of the sheet material and which is adapted to be bound to the stack or pile of sheets by the shipping straps or wires.

Another object is to provide a package of sheets which may be handled from any side with a conventional lifting tractor.

A further object is to provide a method of making such a skid and package therefrom.

'These and other objects will be made apparent Figure l is a plan view of the unformed skid blank of the present invention;

Figure 2 is a side elevation of a skid formedfrom the blank shown in Figure 1;

Figure 3 is a cross section through the skid taken along the line IIIIII of Figure 2;

Figure 4 is a plan view of a completed package of sheets showing the manner in which the skids of the present invention are used; and

Figure 5 is a side elevation of the package shown in Figure 4. 1

With particular reference to the drawings, the unformed skid blank 2 of Figure 1 may be any grade of sheet steel readily available; sheet mill rejects being a convenient source of material. The material is preferably 11 or 12 gage, but heavier metal can be used if forming equipment of adequate capacity is available. Metal lighter than 12 gage, however, should not normally be used for reasons of strength. The length of the blank is substantially equal to the girth of the to a metal skid fdr thesblank'is'equa1 to=the-=length of the -skid.

".f 2 skid-to be formed-theref-rom and the'width of 1': The-

lines

4, 6 and 8 in Figure l-representbend lines and define the top portion l0, side portions .12 andbottom portions and 16 of theifinished skid. The lines-i8 are .1 spaced from the longit-udinal edge of theblankby anamountequal to about half the height of-the-finished skid; Op- 'positely disposed. 'right triangular shaped notches 18. are made in: the. side portions l2, one leg of each right triangle lying :along-the-edge of.the

blank,.the other along 'theline 6: Thenecessary cuts indicated by thefreferencegnumbers l9 and 20, are made to terminate at the intersection of bend lines 6 and 8, and preferably to make an angle of about 45 at this point. A transverse slotted hole 22 is punched in each of theside portions l2 adjacent bend line! at about the longitudinal center line of the blank.

A skid 24 is formed by bending the blank .2

downwardly at right angles at the bend lines 4,

then inwardly at the line 6 so that the ends of the blank abut at about the center of the bottom of the skid. The portions of the bottom identified by the reference number 5 are bent upwardly about bend line 8 so as to incline at about the same angle as the miter-cut 20 in the side portions l2. This construction provides a substantially open-ended rectangular box section having oppositely disposed transverse slotted holes 22 in the sides near the top thereof and having the front and rear edges of the bottom chamfered.

At least four of the skids 24 are used in making a package of sheets, the number being increased in multiples of two as required by the length and the weight of the material of the package. I have found that six skids provide a particularly convenient and adequate support for most'sizes of sheet material shipped. In a package using six skids as shown in Figures 4 and 5 the skids are arranged in

pairs

26, 21 and 28, the skids of each pair being spaced apart and aligned with respect to their transverse axes, i. e., the slotted holes 22 in the skids of each pair are aligned. The pairs'of skids are spaced apart end-wise in two parallel rows A and B, the skids in each row being aligned length-wise. depends upon the size of the sheet material, and is such as will provide a stable package. A transverse tie wire or strap 30 is threaded through the slotted openings 22 of the skids in threaded through the open ends of the skids in each row. The sheets are then piled on the skid The exact spacing skids are readily handled and stored, and can be returned to the shipper for re-use.

While I have shown and describedaspecific' embodiment of my invention, ,1 do not wish to be limited exactly thereto except as defined in the scope of the appended claims.

I claim:

1. A package comprising a plurality of sheetmetal skids, each having two parallel sides with oppositely disposed slots therein and substantially open ends, said skids being arranged in pairs with the oppositely disposed side slots of each pair in alignment, said pairs being arranged in a spaced end to end arrangement to form two substantially parallel rows, a stack of sheets-supported on said skids, tie wires passing through the aligned slots of each pair of skids and encompassing the pile of sheets and tie wires passing through the open ends of the skids in each row and encompassing the pile of sheets.

2. A package comprising a plurality of sheet= 4 metal skids, each formed from a single metallic sheet to provide a top, two sides, a bottom and substantially open ends, said sides of each skid having oppositely disposed slots located adjacent the top thereof, said skids being arranged in pairs with the oppositely disposed side slots of each pair in alignment, said pairs being arranged in a spaced end to end arrangement to form two substantially parallel rows, astack of sheets supported on said skids, tie wires passing through the aligned slots of each pair of skids and encompassing the pile of sheets and tie wires passing through the open ends of the skids in each row and encompassing the pile of sheets.
