' For the purpose of illustratingthe invention, it is shown as amodification or improvement on the patents to Walter N. Vance, No. 1,560,122 is sued November 3, 1925, and No. 1,620,84lissued March '15, 1927. f

1 The invention in the present construction possesses a number of novel features not disclosed in the prior mentioned patents, and it-is to these features that the claims of the present invention are directed.

The rack is preferablyof a construction adapted to be installed between the floor 2 and ceiling 4 of'any desired storage space. Generally, the rack comprises a relatively elongated base plate-6, to which a plurality of spaced apart angularly arranged clamps 8 are fastened each such clamp having an upstanding flange 10 adapted to receive bolts I2; These bolts, in turn, secure a pair of hollow vertical posts l4 and It in rigid upright position. Each one of'iche'se posts is formed of sheet metal of relatively heavy gauge stock bent upon itself to form a hollow, rectangular construction with the opposed ends l8 and 20 extending vertically and juxtaposed. The two posts 14 and I6 are exactly alike so that the flange portions 18 and 20 face each other and receive therebetween a sheet metal strip 22, which may besecured between the 'posts by welding or in any desired'manner, whereby to form a vertically extending rigid post construction, -which projects upwardly to the ceiling 4. At the top the posts l4 and I6 receive bolts24 and 26 which engage an outer angle'clamp or plate 28, in turn bolted as-at 30 to the ceiling member 4. In addition to the two exterior posts l4 and I6, which extend full length from the floor to the ceiling, there is provided a plurality of intermediate spaced apart posts 32 which are identical in construction and are fastened to the base strip 6 by identical angle These intermediate posts, however, extend short of theceiling 4, but at the top are bolted or welded to a horizontally extending cross brace 34, which is bolted as at 36 at each end to the outermost vertical hollow posts Hand I6 (see Figure 11).

In addition, there is, if desired, a series of lower horizontal cross braces 38 which are bolted to pairs of adjacent vertical posts I4 and 32, whereby to provide rigidity. So also, there are used a number of diagonally extending struts. An uppermost strut 40, which is bolted by means of the bolt 24 to the outermost posts I4 and by the bolt 42 to the top horizontal cross brace 34. In addition, there are other diagonal struts 44, 46, 48, and 50, which are bolted between the outermost vertical posts I4 and the next adjacent vertical posts 32. These diagonal struts lie in vertical planes, and firmly and simply rigidify the entire skeleton frame work. 1

From an inspection of Figures 1 and 4, it is to be seen that the vertical posts l4 and I6 and the intermediate posts 32 are provided with a series of vertically disposed, spaced apart bayonet slots 52, which slots are arranged with the head portion uppermost, so that, when a pin or tang is inserted in the wider space at the head, the tang may be forced downwardly to be firmly lodged within the narrower throat of the bayonet slot in a well known manner. By reason of these vertically spaced slots, various spaced apart adjustments to the cantilever shelf members (hereinafter described) are provided.

A plurality of oppositely extending, spaced apart, adjustable cantilever shelf supports 53 are provided, each of which comprises an elongated, angular strip 54 (see Figure 9), which is bent at the middle upon itself to provide an outer rounded end 56 and two spaced apart ends 58 and 60. The metal of the horizontal flange 54 of this angle iron stop 52 is cut away as at 64 and 65 at the outer end and at 58 and 10 at the inner end. In addition, each one of these cantilever arms or supports includes a sheet metal brace and covering I2, generally in the form shown in Figure 9, which is arranged so that the upper edges 14 and I5, as shown in Figure 5, lie flush with the upper edges I and 80 of the angle arm 54. This supporting member I2 is provided with a diagonally inclined undersurface 82, which at its lower edge constitutes a relatively broad bearing 84 adapted to engage the sides 85 of the vertical posts I4, I6, and 32; and, in addition, the member I2 is provided with an outer edge 88 (see Figure 4) which engages the lower edges 90 of the angle arms 53.'

As shown in Figure 4, the outer end of this sheet metal member 12 is riveted as at 92 to each side of the angle arm 53, and at its innermost end is riveted as at 94 to the innermost ends of the angle arm 54. In this connection each one of these rivets 94 is provided with a large head or tang 96 which is adapted to enter the wider, upper portion of the bayonet slots 52.

In addition, a bolt or pin 98 is adapted to pass through registering holes I00 in the lower portion of the member I2, as shown in Figure 5, for the purpose hereinafter described. This bolt likewise passes through the head or wider portions of the immediately beneath bayonet slots formed in the vertically extending posts I4 and I0.

Each such cantilever arm thus extending outwardly from the vertical posts is arranged to support an elongated, relatively narrow individual shelf I02 formed of sheet metal. These shelves are shown in Figures 3 and 4 and, as formed, extend considerably beyond the rounded or folded end 56 of the beneath angle iron. Each such sheet metal shelf I02 is preferably curved downwardly as at I04 its two longitudinal sides so as to provide a mantled from the vertically extending posts, and

while also the inner end of the overlying sheet metal shelf may be rigidly held down upon the beneath, underlying supporting angle iron. To

at its outer end and along this end, the inner end of each shelf I02 is slotted as at II2 to provide a bent-down tang H4 having shoulders H6. The neck II5 of this tang II4, as shown more clearly in Figure 5, is adapted to lie between the opposed longitudinal edges H8 and I20 of the upwardly extending arms of the angle iron 53 and the shoulders H5 thereof, thereby underlying the horizontal spaced apart flanges of this angle iron, whereby the innermost end of each shelf member is held snugly down upon the inner end of the angle iron construction by means of these tangs.

At the same time this construction will permit the two innermost ends of the arms 53 to be shifted outwardly whereby to disengage the tangs 96 carried by each one of these arms out of the upper ends of the bayonet slots 52in the manner shown in Figure 8, and this is accomplished by removing the bolt 98 and inserting a tool I22 which has an angularly disposed operating head I24 through the aperture I26 in the top of the shelf I 02 at its innermost end. When this tool is properly inserted by giving a ninety degree turn, it will force apart the innermost ends H8 and. I20 of the arms 54, whereby to spread tangs 96 outwardly and away from the slots 52, whereby the entire cantilever arm construction with its connected shelf I02 may be dismantled or removed from the vertical hollow posts, and in a similar manner whereby each one of these arms may be assembled in adjustable position to the hollow posts, when desired.

By reason of the foregoing construction, it will be appreciated that each cantilever arm has rigidly and permanently connected thereto its individual, elongated sheet metal shelf construction which is'connected in such a way, so that, while the sheet metal shelf is permanently united .to the underlying angle supporting arms 54, it still permits these angle irons to be spread apart so as to permit practically instant installation of the cantilever and shelf to the vertical supports, or permits their removal therethrough, and this is accomplished by inserting the parting tool through the only aperture of the sheet metal shelf to permit dismantling in a minimum of time and with facility. Thus, there is provided a very simple, rugged, compact shelf construction possessing the inherent characteristics hereinbefore described.

Changes may be made in the form, construction, and arrangement of the several parts with out departing from the spirit of the invention or sacrificing any of its numerous advantages, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claims.
