Claims, (CL-,189736) My invention relates to storagejacks and moremparticularly to portable racks for` storing pallets, sheets, ,barM stock,- or the like. v

The object` of A my invention` is,to provide ai rack that is easily assembled and `disassembled `to `anywsize,` as to length, height, depth, and` withyaried numbers of cross. 4supports at varied heights.`

Another object of ymy invent-ionis `to provide astoragen rack that is slidably supported for adjustment .ofthevertical standards for any variation, inthe ysurface,l orwfloor, to which the rack is` applied.,- i

Still another?` object of,my invention-sis `to provide a rack that supports itself rigidly in a vertical plane,` with@ out weaving,` or. leaning, oneyway-onthe othera when WeightY is. applied ,i to the cross. members;` forming:v the, shelves.

It is manifest to anyoneamiliar with racksvfor storing materials, that when the ,racks Aareof a permanent nature and constructed rigidly,` they ,very,oftei1-` outgrow their capacitywhich is limited to theirgoverningdimensionsV It is` also quitefrequently necessaryto move the racks toa dierent location in theplant'lor warehouse,rand -duerto their permanentustructurefit 1involves quite an expense in labor, and loss of nmateriaLin-makingthis change of location.

The device described and` illustratedwherein represents; a direct improvement on 'theracksi-such as `covered by my Patents Nos. 2,510,433 .a`tndr2,7l0,735.V Itpresents the portable feature being easily manipulated in ,standard parts, arranged for, easy assemblyand disassembly, they braces are arranged to` retain thestandardsingarvertial plane at all times, evenV when thepfleori-is uneven OliA slanted. The crossmembers are constructed in da, manner to prevent side sway or leaning, aridwarereasilyassernbled` with the vertical standards to.provide, racks/of` varied widths, depths, and heights, withmthe ,cross-,bars placed at Varied heights, one above the other.

Other and further objects of my invention will'become more apparent as the description proceeds, when taken in conjunction `Withthe drawings in which:

Figure 13 is a perspectiveview of themodiiieltype of bracket as shown in Figure r 1l,` withthe ,tubular cross brace `welded thereto; and

Figure 14 is `a front view, of the.assembly asshown in the variousA4 Figures 9, l0, l2, and 13, showing the cross as 13,-and of alength to reach from one vertical standard The., cross-brace 13 is equipped with a at end plate 14of a width equal to the diameter of the cross-brace 13, andof a length which is greater than the width of the space between angle irons 11u and 11c and `may be equal tothe length of the spacer channel 12, The ends 15-of the` fiat `end plate are curved slightly, as shown to make it easier to` put them into` place. T here are a pairV of outwardly extending members 16 which are radially formed atu 11 for engagement` with the outer surface of the cross-brace 13, whenwelded thereto in opposite ,relationmto one anotherand in alignment with one another. Thesemembers 16 are `spaced fromthe end plate 14 at `afdistancejust slightly greater than the width of the legs ofthe` anglesll, 11a, 11b, and 11c in the vertical standard 10.` This` provides for ample clearance at 18, as shown in Figures Zand 3, when the cross-brace 13.is in position with the endrplate 14 resting on topf` ofthe-spacer channel at 19, as shown in Figure 2-` When installing the cross-memberil into engagement with the vertical standard 10` it is only necessary to `insert theA flat plate- 14,be t weenthe angles `such as, 11b and 0 11, and by revolving the cross-member 13 a half turn the end plate 14 will rest on the spacer channel 12 with the angles 11b and 11c spaced between the end plate 14 and the members 16. The side portions of the tubular member 13, between the

members

14 and 18 tend to contact the angle irons and prevent lateral displacement.

The members 16 may be straight at their outwardly projecting ends, or cut radially, as shown by dots in Figure 8. Since the surfaces of the members 18 are ilat they will tend to contact the outer face of the

angles

11b and 11, thus preventing the vertical standards from Weaving or leaning sideways as would be the case This `is to provide, space to` 3 if a pin be inserted through the tubular cross-bar 13 at the point of contact with the angles.

In Figure 7, I show a brace clip 20, `formed into a channel at 21, for engagement with one web of the angle as shown in Figures and 6, and the longer section thereof is angularly disposed at its end 22. There is an aperture 23 disposed through the brace clip 20 to accommodate a bolt 24 so it may be assembled with a straight brace 25 and an angularly disposed brace 26,

when placed in position to clamp the-angleasshown in Figures 5 and'6. This type of brace clip permits the assembled brace extending from one vertical standard to the other to slidably adjust itself and clamp securely when the bolts 23 are fastened and tightened.

The modied bracket construction shown in Figures 9 to 14, inclusive, accomplishes the same purpose as outlined above, and consists of a pair of oppositely disposed

sections

27 and 27 for-med into a U shape and welded together at the line 28, to` provide oppositely disposed plates 29 answering the Same purpose as the plate 14, namely, for resting on the spacer channel 12 forming an integral part of the vertical standard 10.

There are other'oppositely disposed contact plates 30 forming an integral part of the U-shaped

sections

27 and 27. These contact'plates 30 act as a support for the tubular cross brace'13, which is welded to them at its surface, as at 31. l

, The members or portions 32, when the bracket is assembled with the angle irons, terminate a slight distance from the faces of the angle irons, thus preventing lateral displacement of the bracketand brace in a generally horizontal plane. Thus the portions 32 perform the same function as the tubular side portions between the

members

14 and 18 in Figures 1 through 8. t Y

There are angularly projecting members32 integrally formed with the contact plates 30, which act as guides, or spacers, as shown in Figure 10 at 33, for preventing the bracket assembly from shifting, or sliding, between the angle irons forming a part of the vertical standards 10.

In assembling a rack, a plurality of vertical standards as shown in Figure l are disposed in the spaced relation desired and the desired number of cross braces or supports 13 and

braces

25 and 26 connect the standards.

It will be seen that the -generally horizontal crossbraces 13, may be easily inserted into and assembled with the vertical standards 10, and when supported by the spacer channels 12, which are an integral part of the vertical standards 10, will prevent any side sway of the standards, and when the braces are assembled and clamped to the vertical standards 10 as shown, they will rigidly support the standards and retain them in vertical alignment even though the floor may be uneven.

Whereas I have shown and described an operative form of my invention, I wish it tov be understood that there are many modifications of this invention which will fall within the scope and spirit of the invention and which will be apparent to those skilled in the art. The drawings and description of the invention should be taken in a diagrammatic ortillustrative sense and the scope of the invention should be limited only by the scope of the hereinafter appended claims.
