METAL SHELVINGL the provision of a back which can be po-.

sitioned after'the frame is set up and without moving the frame away from the wall or out of an alcove in which it may be located The shelving of the character to v which this invention more particularly per tains is furnished in knocked-down condition and is assembled ordinarily at the location Where it is to be finally installed. To the end that the shelving may be set up with the greatest facility, the parts of the embodiment of the invention about to be de: J scribed are so constructed that they may be adjusted and secured together wholly from the front.

A further and important object of the in vention is the provision of shelving of this character particularly designed to carry severe loads, such loads of course cause deflection of the parts and my invention'contemplates the construction of the shelving so that this deflection within the prescribed or elastic limits of the material will not be objectionable either by reason of appearance or consequent separation of the parts.

Another important object of the invention is the provision of the shelves so constructed that maximum strength is provided.

Another important object of the invention is the provision of a readily positioned bin front which may be used or not as requirements may dictate and which may be substituted readily for others higher or lower and without requiring special formation of the other parts of the shelving. A still further object of'the invention is the provision of a new and improved construction of the parts to facilitate the positioning of the label holding devices.

Although the invention 1s believed to pertain rimaril to open shelves, it will be mani est as t e' invention is better understood that numerous features or parts are Specificationbf Letters Patent. Application filed October. 25,1917. Serial No. 198,408.

For the purpose of illustrating my invention I have shown on the drawing what may be termed a shelf unit, the complete shelving consisting of a multiple duplication of the parts shown. These parts comprise four uprights 21 which may be multiplied in number and in length, only suflicient up- .rights being shown on the drawing to suprights is of rectangular horizontal section flange 25, which flanges 25 of each upright the flanges 38 extend between the .flangesin the I edge of a partition 26 extending vertically -and from front to back; the edges of each port twoshelves of the same vertical tier. .n the present instancdeach of these uphaving an outer imperforate wall 22, side slotted walls 23 and inner wallsconsi sting of two halves 24, each terminating in a extend outwardly from the upright and toward the corresponding upright in front-toback alinement therewith; Each pair of resent instance embraces an of these partitions are firmly held between the flanges in any suitable manner. The

slots 27 of the uprights are duplicates each of the others and 1 are arranged at intervals in two side walls 23 and they are of T shape. An upper part 28 is larger than a lower part 29, the side edges of the uprights forming these parts being preferably tapered so-that the lowermost" end of each slotted part is smaller than its uppermost end. Cross supports 31 having a neck portion 32 near eachend and-a head 33 therebeyond are engaged in appropriate slots 27 and serve to support the shelves proper. Each of these shelves consists of 'a metal sheet which rests at-the front and back upon two cross supportsBl and secured as will be presently described at its side edges to the partitions. At the front and back the shelves extend beyond the cross support. to the outer edge of the" uprights and are bent downwardly at 34 to about the height of the I lower edge of the supports and are then bent -1nwardly at 35 to provide a flange 36 nearly closing the space between the outer part 37 between the bends 34 and 35 and the shelf support 31. At the sides these shelf sheets are provided with flanges 38 which are bent downwardly to /be disposed alongside the adjacent partition '26 to which they are secured by bolts 39 through appropriate apertures in the partition and in the llanges'38.p The corners are cut away on a right angle 7 at 41 to fit about the uprights or postsand postparts 34, the flange and shelf body being bent at the points 42 to accommodatethe flanges 25 of the uprights. v This feature has been found to be of material importance as it adds greatly to the load bearingoualities of the shelves. That is to say, the shelves can carry a greatly heavier load than they are able to carry if the material were cut away to accommodate the flange 25 instead of being bent as just described.

The space between the uprights at the rear is closed by a vertical wall 43 which is perforated to form round holes 44 appropriately arranged at intervals and near the side edges. This vertical wall, or back in .the present instance has its edges overlying the outer faces o f-the adjacent uprights and arness it is secured in place by a number of clips of different form now about to .be described, it.being understood, howeventhat all of these clips need not be used although their conjoint use is thought to provide the best a construction.

Considering first clips indicated on the drawing'at 45, which may be termed side clips and which secure the back 43 to the uprights,- it will be noted by comparing Figs. 1, 5 and 14 that each of these clips consists of a strong sheet metal strap having its ends 46 and 47 bent in order that the end 46 may engage through a-perforation 44 in the back and through one of the slots 45 in the upright. The end 46 is of reduced form and serves as an interlocking tongue when installed through the aperture 44 and given a rotative movement to bring the end 47 into the slot 27.

The connection between the tongue 46 and the aperture 44 is in effect a universal joint permitting the end 47 to have a plurality of movements,

first into position inthe upper part of'the slot and then down into the lower part. The end 47 is provided with top and bottom notches 48 "where it engages the material of the upright and the clip is bent intermediate its edges as indicated in Fig. 5 to lie close along the back wall and close also along the upright; These clips thus interlock with both the uprights. and back or vertical wall and bind the uprights and Vertical wall together. V 5 I ,:Two clips or shelf supports 51 are also provided to hold the vertical wall close against; the vertically extending part 37 of the shelf. These clips are secured in place through perforations 52 in the back wall and 53in the shelf. Each top clip has a reducedend 56 formed into a bent tongue and engageable through an appropriate perforation52. The other end of the clip 51 is perforated to receive a bolt 57 also-"extending through the perforation 53 in the shelf.

This clip is positioned by having the tongue 56 inserted through a perforation 52 and then springing the clip upwardly until its other end 58 contacts with the underface of the shelf and in position to receive the bolt 57. Two of the walls of the shelving are thus locked together, these walls in the present instance being one of 'the shelves and the back although the clip may be used newness upon the lower cross support in the manner shown and described. The shelves are then placed in position and the backs slid down from above and behind the uprights.

- until its lower edge 62 rests with the lower edge of the shelf in the channel formed by the end 63. The other clips may then be inserted from the front by placing" the tongues 46 and 56 through appropriate apertures 44 and 52 respectively and the other ends of these clips connected in place as already described.

It is frequently desirable to close a part of the space between the uprights at the front of the shelves and to this end I provide binfronts indicated at 71, which bin fronts are arranged to be positioned after the entire shelving is set up and these bin fronts may be of almost any height desired. Each bin front comprises a metal sheet adapted to fit between the adjacent front uprights and has its edges bent to provide loops 72 and 73 which embrace holding dogs or latches 74, one beingarrariged at each end of each embracing loop. ach of these dogs or V latches has a tapered forward end 7 5 adapted to engage in appropriate slot 27 and at its rear or other end is bifurcated, the bifurcation extending almost to the end 75. These dogs or latches are stamped from suitable heavy material and the tapered end 75 of one results in a tapered recess at the other end of the adjacent do or latch formed in the punching. A slot 6 connecting at one end with the tapered recess 77 just described produces the bifurcation mentioned. In one edge of each dog or latch a slot 78 is provided to permit the manipulation of the dogs or latches when in place in the bin front, The loops 73 are cut away at 79 to exposethis slot and to permit it to be engaged by a suitable tool to retract or project the ends 75 as occasion may require. The dogs are held tightl in the embracing loops of the wall or bin ront, the bifurcated end rendering them somewhat yielding.

When the .bin front is positioned the two lowermost dogs enter into the slots 27 in which the cross support just beneath is se- -cured. The tapered ends of the dogs enable them to engage in slots higher up and at any desired heights in said slots,-the difference in cross sectional area of the slots being taken care of by the extent the dogs are caused to project. It will. be manifest,

therefore, that the only heights at which bin fronts cannot be provided are heights that would bring the dogs between the successive slots. As these slots are placed relatively purposes bin fronts of any desired height can be inserted or substituted for others already in lace.

The she ving shown n the drawing is adapted to carry heavy loads and of course a consequent resulting deflection is sustained by the cross supports and also by the shelves which are more readily bendable. In order that this deflection shall not destroy the appearance of heavily loaded shelves I give to the cross supports a camber so that the deflection from unloaded to loaded condition is divided upon both sides of the true horizontal and is therefore almost imperceptible to the eye. The edges 'of the bin fronts are straight and in order that the bin fronts may follow the deflection of the front, I provide central perforations 81 extending through the lower embracing loop 72 and through the shelf in which a bolt 82 is secured.

The front vertical parts 37 of the shelves form desirable label carrying parts and label holders are secured thereto. These label holders each consist of a channel member 91 adapted to be fastened at a plurality of points to a shelf edge. The fastener is formed from the holder itself by providing a pair of slits 83 and depressing the material between them as seen on a large scale in Figs. 8 and 9, the slits 83 setting off the bottom of the depression from the remainder. The depression is so formed that this connection 84 and the transverse center 85are narrower than the intermediate parts.

An oval or elongated aperture 86 is formed of the shelf. When the label holder is to be positioned the depressions are brought into registration with these apertures and a punch or nail set driven in the depression which results in a separation at the center and a straightening back of the two halves of the depression thus formed. Each of these halves form all undercut lu 87'engaging back of the narrower ends of the. recess thereby securing the label holder inlplace.

- It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and .ar rangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
