METALLIC SHELVIN G.

Specification of Letters Patent.

Patented Jan. 14, 1913.

To a l whom it may concern Be it known that I, ARTHUR MARTIN, a citizen of the United States,- residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Metallic Shelving, of which the following is a full, clear, and exact description.

The invention resides in certain novel features of construction which results in the thoroughly practical knock-down shelving, as shown in the drawing and hereinafter described and claimed,which shelving is of moderate cost, and is easily assembled, and is capable of indefinite lateral extension by the addition of suitable duplicate parts.

In the drawing, Figure 1 is a plan view of one unit of the-shelving and a small part of 'bers a.

another unit. Fig. 2 is a front elevation, partly-sectioned,of the parts shown in Fig. 1. Fig; isaperspective view of two associated end piists and two of the shelf supporting braces employed in connection therewith. Fig. 4 is a perspective View of one 'end of one of said shelf supporting braces.

Fig. 5 is a sectional plan view of one post and the ends of two of said shelf supporting braces. F ig. 6 .is an end elevation of a part of one of the postsyand Fig. 7 is a perspective View of a part of one of the shelves, said shelf being sectioned from front to back. Fig. 8 is a plan View of a modified construction; and Fig. 9 is a front elevation partly broken away and sectioned of said modified construction. I

A single section of the shelving shown will include four corner posts A; these posts are of channel iron form, each comprising a central member a and two'integral side mem- In these side members are the vertical slots a which are enlarged at their upper endsfor a purpose Which will subsequently appear.

B, B represent bars which serve .as braces, and as shelf sup-ports. These are made of fiat pieces of metal, the ends 6 of which are turned over into the same direction so that they lie at substantially right angles to the main part of said bar. On each of these turned over end pieces is a boss b. The slots (1 are of such width at their lower ends that the turned over ends I) fit nicely therein, and these slots a are enlarged at their upper ends so thatthe part of said ends I; on

ends of the shelf.

which are the bosses b may pass through them.

Two posts are placed in upright position With the side members of the front post extended rearward and the side members of the front post extended forward. Then the turned over ends of the bars B and the bosses b are passed through the enlarged upper ends of the slots a and thenth'e'se bars are forced down into the narrow parts of the slots a When they are in this position the bosses b engage the one face of the side members a of said posts, and the side of the bar engages the other face of said sidemembers. These slots at are placed at any desired distance apart and any desired number of them may be employed. The

bars B are placed in the manner described in engagement with both side members of both.

posts, that is with a frontand a rear post, as shown in Fig. 3. These two posts, and a suitable number of bars B constitute one end of the shelving structure, two of such ends being required for the first unit of shelving. These two ends are bound together by means of the shelves D. Each shelf has at its ends a laterally projecting portion d which fits more or less closely between the approximate edges of the side members of two end post-s. Thisprojecting portion is preferably curved downwardly and under so that its edge will come close to the inner face of the bar B on which it is supported. Both ends of the shelf near the front and rear edges thereof are cut away as shown so that these out back ends (i will come very close to the side faces of both the front and rear posts, and at both In Figs. 1 to 7 the turned over ends I) of bars B are passed through the slots (E, from the outside of the side members, and consequently the said turned over ends, when in place are in the channel between said side members. But in the construction shown in Figs. 8 and 9 these turned over ends are passed through the slots a from inside the channel of the post. In this construction therefore the projecting parts of these turned over ends-pass beneath the shelf and aid in supporting it. With this latter construction the reinforcing angle irons C may be omitted in some cases.

It is not necessary, although it is desircured at their lower ends it will be perhaps,-

rigid enough for ordinary use. Now, in order to extend the shelving laterally by adding another section, two end posts and their associated bars B must be provided, and be placed in proper relation to the shelving section first described. Then the shelves D will be put into place in engagement with the outside bars 13 of the finished shelving unit and the inside bars B of the added end.

In order to make the shelves employed absolutely rigid, their front and rear ends are turned down; and angle irons C are placed inside the angle formed by so turning these ends, and these angle irons are secured in place by turning the edges of the shelf under and up against these angle irons, as shown in Fig. 7.

Having described my invention, 1 claim:

Metallic supports for a single section or unit of extension shelving composed of four upright channel-shaped metal posts arbeing disposed with their central Webs outwardly front and rear and their side flanges opposltely arranged in corresponding planes, flat metal brace bars adapted to connect the posts of each end pair and also to support the shelves, said brace bars having end members abruptly bent at right angles in the same direction and formed with transversely projecting side bosses, serial vertical slots in said side flanges longer than the width of said brace bars Wide at their upper ends and narrower at their lower ends, the bent bossed ends of the brace bars being passed into the wide upper ends of said slots and then pressed down into the narrower portions thereof, the flange thickness of the post being snugly embraced between the flat faces of the brace bars on the outside and the adjacentfaces of the bosses on the inside, with shelving resting upon the upper edges of said brace bars.

in testimony whereof, [I hereunto atlix my signature in the presence of two witnesses.
