14 Claims.

This invention relates to improvements in metallic bookracks, shelving and the like. In structures of this sort, particularly in library stack shelving, the shelves commonly extend between and are supported at their ends by uprights or supports which form the end walls of the shelving and, in order to reduce the weight of the structure and yet provide the requisite rigidity and strength for carrying the weight of the shelves and their load, these uprights are frequently made of sheet metal and of hollow or tubular formation and provided with slots for the engagement of parts on the shelves or on shelf-supporting members for supporting the shelves. It has been found, however,

a that such constructions, in which these slots communicate with the interior chambers of the hollow uprights, are open to serious objectionsince they provide cavities which allow the lodgment and accumulation of dust or foreign matter and form hiding and breeding places for insects or vermin, and therefore make it difficult to keep the structures in proper sanitary condition and preserve the contents of the shelving. e

One object of our invention is to provide shelving or the like in which the shelves are supported by uprights of lightv hollow or sheet metal formation but in which the uprights are constructed and the shelves connected therewith in such a manner as to avoid the above noted objections.

Other objects of the invention are to produce a shelving or like structure of novel construction which will be strong and rigid and of good appearance, and in which the shelves are removably arranged so that they can be readily placed in position and removed, and adjusted as required to provide diierent desired spacings between them, while nevertheless the shelves are held in place against unintentional displacement both lengthwise and crosswise and also serve to tie together the uprights and brace or strengthen the structure; and also to improve shelving and the like structures in the other respects hereinafter described and set forth in the claims.

The accompanying drawings illustrate several different embodiments of our invention. In said drawings:

Referring first to the construction shown in Figs. l, 2 and 10-14, the shelf-supporting upright A is of hollow rtubular shape formed by opposite spaced sheet metal side plates joined or meeting at their opposite, vertical edges. The upright, as shown, is intended to support two tiers of shelves, arranged back to back, and is therefore formed at its opposite vertical edges to provide supports for the outer edges of the shelves of the two tiers, and is formed between its opposite vertical edges to support the inner edges of the shelves. Only one of the outer edge formations of the upright is shown in Fig. 1, but it will be understood that its opposite edge may be of the same or other suitable formation, as hereinafter explained.

The outer edge formation of the uprights may be constructed in various ways, that shown in Figs. 1 and 2, and` 20 being at present considered as a preferred arrangement.

In this construction, the opposite side plates 25 are formed adjacent the outer edge of the upright with inbent portions 26 provided with outwardly projecting ianges 27, and between the opposite vertical edges of the upright, the plates 25 have depressed portions 28 which abut face to face and form vertical grooves 29 in the opposite faces of the upright, the purpose of which will hereinafter appear. The upright is also provided at its outer edge with opposite, laterally projecting vertical flanges 30 spaced from the inbent portions 26 of the plates 25 so as to form vertical grooves 31 in the opposite sides of the outer edge portion of the upright. The flanges 30 may be formed by bending these portions longitudinally upon themselves to make the double-thickness flanges 30 shown, thus providing strong and neat vertical edges therefor. The edge formations are preferably provided with a central vertical bead 33 which gives a desirable finish to the front edge of the upright. In said Figs. 1, 2 and 20, said bead 33 is formed on an edge of a separate strip or insert 32 which is placed between and in engagement with the flanges 27, the

abutting parts

27 and 32 being rigidly secured together, as by welding.

The upright could be constructed in various diiferent ways to provide opposite lateral anges and grooves at its outer edge portion. For eX- ample, it could be constructed as shown in any of the Figures 4 to 6.

In Fig. 4 the flanges and grooves are formed by opposite abutting ystrips 34 which are bent to provide the lateral flanges and grooves and which strips extend between the inbent edges of the side plates 25. The strips 34 may be secured together and to the side plates as by welding.

In the Fig. 5 construction, the lateral anges are formed by two angle-shaped strips 35 which are secured,'as by welding, against the opposite outer faces of the outwardly projecting flanges 2'7 of the two side plates 25 of the upright.

As shown in Fig. 6, the outer edges of the flanges 27 of the side plates 25 are bent outwardly and folded back upon themselves to form vthe lateral flanges 30, as in the first construction, and the edge portion of the upright is strengthened by a thick metal strip 36 which is secured, as by welding, between the flanges 27.

In the construction illustrated in Figs. 10 to 14, the front flanges 30 of the uprights A are formed by a sheet metal edge strip made from a blank such as is shown in Fig. 3. rThis blank is folded lengthwise upon itself along the broken lines to make the double-thickness flanges 30, and inwardly extending edges 36, which straddle the flanges 27 and are securedv thereto by welding. The bead 33 in this construction is formed integrally in the strip. 1

Each shelf B is preferably formed at each end, adjacent its opposite edges, for engagement with an adjacent upright so that the upright will support the shelf both at its outer and inner portions. For this purpose the shelf shown is provided at each end adjacent its front edge with an endwise projecting tongue 37 having a downbent end flange 38, see Fig. 12, adapted to project into the groove 31 of the upright and rest in any one of a series of notches 39 in the edges of the fianges 30 of the upright. These notches, in the construction shown in Fig. l, are formed by the slots 39a shown in the blank, Fig. 3. The flanges 30 of the upright can be notched in any suitable way, preferably the notches 39 are of angle form and the tongue flanges 38 are notched as shown at 40 so that these parts will interengage and thereby prevent either longitudinal or transverse shifting of the shelf so as to allow unintentional disengagement of the tongue from the notch ofthe upright.

The upright may be of various different constructions or formations adapted to support the shelves at or adjacent their inner edges` For instance, as shown in Fig. 1, channel-shaped strips 41 secured in grooves 29 in opposite sides of the upright, as by Welding, have their projecting edges notched to form spaced lugs 42 on which downbent stiffening flanges provided at the ends of the shelves are adapted to bear to support the shelves.

With the described formation of the upright and shelf, each shelf can be slipped rearwardly into place between two of the uprights A until its end flanges rest on an opposite pair of lugs 42 of the uprights, and the tongues 37 at the outer edge of the shelf enter a pair of notches 39 in the outer flanges 30 of the uprights, the shelf being pushed inwardly until the tongues strike the inner walls of the grooves 81 in the uprights, which will arrest the shelf with the notches 40 in the ends of the tongues 37 registering with and adapted to straddle the lower edges of the notches 39 of the uprights. r.The shelf will thus be prevented from shifting either inwardly or outwardly unless its front edge is lifted sufficiently to disengage the notches 40 from the outer supporting lugs of the uprights. Furthermore, when the shelf is in place between the two uprights, the hook-like lugs formed by the angular notches 39 will engage the inner faces of the end anges 38 on the shelf tongues and prevent accidental shifting of the shelf lengthwise out of engagement with the lugs, the shelf thus acting to tie together or prevent the spreading of the uprights. The shelf-supporting notches or lugs of the upright are so spaced as to permit the usual adjustments of the shelves to different desired distances apart.

Several different constructions of the inner or middle shelf-supporting portion of the upright are shown in the drawings. For example, Figs. 13 and 14 show a construction in which the sheet `metal side plates 25 of the upright are reinforced by vertical, metal lug strips 45 which may be secured in place with an interposed spacer 45 betweenthe side plates 25 by bolts, welding or otherwise and are provided with struck-out lugs 47 which project out through and closely flt in slots in the side plates 25. The usual depending stiffening flanges at the inner edges of the shelves may rest on these lugs, as indicated in Figs. 10, 13 and 14.

Figs. 15-17 show another construction in which sheet metal channel strips 48 are secured in the grooves 29 in the opposite faces of the upright. These channel strips, the flanges of which are preferably reinforced by folding in their edge portions, are provided with slots 49 into which rearwardly projecting lugs 50 at the inner edge of the shelf are adapted to project to support the shelf.'

Two other slightly different constructions for this purpose are illustrated in Figs. 18-21. As

'shown in Figs. 18 and 19, channel strips 51 are secured in the opposite vertical grooves 29 of the upright, as in the construction shown in Fig. 1, but their flanges are provided with forwardly and rearwardly bent lugs 52 on which the downbent stiiening flanges at the inner edgesof the shelves bear.

In the construction illustrated in Figs. 2O and 2l the side plates of they upright A aredivided at the middle of the upright, theinner edges of the plate sections being formed withlaterally bent anges 53 and two lug strips Y54 extend transversely through the upright between the' flanges 53 of the sections of the side plates to which they may be secured as by welding. These transverse lug strips are provided at their outer edges with forwardly and rearwardly bent spaced lugs 55 on which the inner edge flanges of the shelves may rest, as illustrated in these iigures;

` Figs. 7, 8 and 9 show still another formation for the front or outer edge of the upright. In this case the upright, instead of being rprovided with the laterally projecting flanges 30, as hereinbefore described, has `secured onfits outer, or front edge face, a vlug strip 56 provided with forwardly projecting hooked lugs 57 on which laterally projecting tongues 58 at opposite ends of the front edge of the shelf are adapted to rest.

It will be noted with reference to each of the constructions illustrated and described that while the shelf supporting upright is of sheet metal or light weight hollow formation, yet it is of strong and rigid construction which has ample loadcarrying capacity. Nevertheless, the openings or notches provided for the adjustable engagement of the shelves with the uprights do not lead into or connect with any interior chamber of the hollow upright. Therefore all of the surfaces or spaces on or in which dust, insects or other foreign matter can lodge are exposed and can be readily cleaned, and there are no hidden or inaccessible cavities for the accumulation of such material.

When an upright A is located at the end of a range of shelving where it would be exposed to View, it can be constructed so that its exposed outer side will present a desired attractive or finished appearance, or instead of this, a suitable nishing or cover wall or plate 60 can be arranged at the outer side of the upright, as represented at the left hand end of Fig. 2G.

The interior chamber of the hollow upright A may be closed at its upper and lower ends by any suitable construction, such for instance as illustrated in Fig. 13 of the drawings.
