LIBRARY SHELF.

Application filed September 25, 1922, Serial No. 590,225. Renewed `June 5,1926.

' tion and arrangement of uprlghts and shelves,

wherein one or more of tie supporting lugs ofthe shelves are ofl'set in order that when a shelf on one side is changed to the opposite side the proper alignment of the shelves will be obtained. f

lt further eomprehends a novel construction and arrangement of shelves and rip-- rights, wherein the uprights at one end of the shelves are provided with locking members while the upright at the opposite end of the shelf is provided with slots through which shell' supporting lugs are adapted to pass, so that a shelfl can be removed when moved laterally and tilted after being slightly raised.

Other novel features of construction and advantage will hereinafter' appear in the detailed description.

For the purpose of illustratingl my invention, l have shown in the accompanyingl drawings, preferred embodiments thereof which are at present preferred by me, since such embodiments will give in practice satisfactory and reliable results. It is tobe understood,however, that the various instruinentalities of which my invention consists can be variously arranged and yorganized and that my invention is not'limited to the precise arrangement and organization of these instrumentalities as herein shown. and described.

)teferring to the drawings,

Referring first to theV construction seen in Figures 1 to 5 inclusive, the end uprights are formed of a plate 1 preferably metal, to which is connected in any desired manner, for example, by spot welding, one flange of an angle 2.

The intermediate uprights are formed by a central plate 3 and diagonally opposed angles 4 and 5, respectively, a flange of each of ` such angles 4 and 5 being spot Welded or otherwise secured to the central plate 3. The laterally extending flange of each angle is provided with a vertical row of spaced apertures 6 which are adapted to receive the headed or hook shaped lugs 7 carried by the These lugs 7 eX- ten'd rearwardly beyond the rear edge 10-of the sides 8. A portion of one of said sides is laterally deflected to form a stop member 11. The shelves may have their book supl porting portion corrugated, as at 12.

In the embodiment seen in Figures 6, 7 and 8, theuprightsl are X-shape in cross section and preferably formed of rolledl metal. The laterally extending flanges 14 of the uprights are provided with a vertical row of spaced apertures'l 15 `which may be omitted in the flanges 16 of the end uprights. One of the sides 17 of the shelves 1S is provided with a plurality of" straightl headed lugs or hooks 19, and the opposite side of the same shelf. is provided `with an offset portion 2O from which extend a plurality of headed lugs or hooks 21. The lugs 2O are thus offset from the body portion of their respective sides 17.

In the embodiment seen in Figures 9, l and 11, the uprights are formed by a central web plate 22 to which is connected at its front and rear portions, preferably by spot welding, a structural metal shape 23 shown for the purpose of illustration as T-shaped in cross section with its head surrounded by a sheathing 24 fromfwhich extends the hooks 25 which are adapted to pass through apertures 26 at one end of a shelf 27, said apertures being formed in a laterally extending flange 29. The shelves preferably have the apertures 30 formed therein by deiiectin g the metal. The opposite end of a shelf has connected with it a supporting bracket 3l having a laterally extending fiange 32 and a longitudinally extending headed lug or hook S3 which is adapted to be received in one of a row of vertically disposed apertures 34e in a flange of an angle 35 or 3G diagonally disw posed on opposite sides of' the web plate 22 to form with said web plate an intermediate upright.

The manner in which the shelves are assembled will now be apparent to those skilled in this art and is as follows Referring first to Figures l to 5 inclusive, it will be seen that when a rear shelf is secured in alignment in a horizontal plane with an end shelf, the headed lugs at the same end of the two shelves will enter the saine aperture and will overlap cach other, and the shelves on opposite sides of the upright can be se cured in absolute alignment with each other since the angle at one end is diagonally op posed to the angle at the other end of the shelf.

In the embodiment seen in Figures -6 to 8 inclusive, it will be apparent that the alignment of a shelf when placed in horizontal alignment on the opposite side of the upright is due to the fact that the flanges are diagonally opposite so' that the proper clearance is provided when these shelves have their supporting lugs secured t0 the same walls; of the upright so that the lugs will overlap and accurate alignment of the shelves will be obtained.

In Figs. 9 and 10 the shelves are arranged in alignment in a horizontal plane.

In the embodiment seen in Figure 1l, the uprights 37 are provided with the ,diagonally dis )osed angles" 38 on opposite sides which are provided with a double row of vertically spaced apertures 39. The shelves 40 are provided at each end with an oll`-set lug 41 so that whena shelf is placed on each side of the two uprights the olf-set l-ugsfwill pass through different apertures.

In theembodiment seen in Figure l2, the construction of the uprigh-ts is the same but the shelves are provided with angular shaped lugs 4t2 which enter the apertures of the angles 38 in a similar manner to that seen in Figure 11 and flanges 43 extend upwardly to serve as stops to prevent a book being pushed in so far that it will be injured by coming into contact with the lugs carried by a shelf on the opposite side from that to which the book has been inserted.

It will now be apparent that I have devised a new and useful library shelf which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described preferred embodiments thereof which will give in practice satisfactory and reliable rcsults, it is to be understood that these cmbodiments are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrilicing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. Library shelving comprising a thin flat plate serving as a central web, angle irons supported by said web, said angle irons being arranged in opposed relation with one flange abutting flat against said web and the other flange projected laterally, said last mentioned flanges being apertured throughout their height, pairs of shelves having headed lugs engaging certain of said apertures, and aligned shelves in a horizontal plane having their lugs overlapping in the same aperture.

2. Library shelving comprising a thin flat plate serving as a central web, angle irons supported by said web, said angle irons being arranged in opposed relation with one flange abutting flat against said web and the other flange projected laterally, said last mentioned flanges being apertured throughout their height, pairs of shelves having headed lugs engaging certain of said apertures,` and aligned shelves in a horizontal plane having their lugs overlapping in the same aperture said shelves each having a projection'to prevent a book coming in contact with the juxtaposed lug of another shelf.

3. Library shelving comprising uprights having secured thereto upon opposite sides thereof angle irons having laterally extending apertured flanges said angle irons: being arranged in reverse directions and shelves provided with sides having headed lugs which engage said apertures, two shelves when in horizontal alignment having their lugs overlapping in the same apertures, and the shelf having a projection to prevent a book coming into contact with the juxtaposed lug of another shelf.
