This invention relates ingeneral to metal shelving and has particular reference to an improved shelf rack for supporting shelf boxes or drawers.

The rack of the invention is adapted for use in stock rooms or other storage places where a diversified collection of small articles are stored in assorted arrangement. A

storage room is ordinarily fitted with a numare positioned. Further disadvantages of such a system are that boxes become misplaced or have theircontents spilled when carelessly withdrawn from the shelves. It is also difficult to inventory the stock on hand. The

provision of separate shelves especially for small articles is both costly and undeslrable because additional space is occupied.

The principal object of the invention is the provision of an improved rack for supporting shelf boxes in compact arrangement and adapted for housing in a shelf space of a standard shelf structure to utilize all the space thereof for the storage of the box inserts.

Another important object of the invention is the provision of a rack of simple construction, consisting of a minimum number of parts yet strong and durable and which provides a rigid structure for the support of shelf boxes within a main shelf structure.

Another important object is the provision of a rack to co-operate with metal shelving of standard design without necessitating the reformation thereof and which can therefore be carried as an auxiliary part to be installed either in shelving under construction or in shelf structures already in existence.

Another important object of the invention is the provision of a supporting rack for shelf boxes having means for preventing the accidental withdrawal of the boxes there METAL SHELVING 1927. Serial No. 191,586.

from and consequent spilling of contents, which means does not impede normal use of the boxes.

Still another important object of the invention is the provision of a sectionalized support for shelf boxes adapted to be manufactured in a number of standard sizes by the mere addition of sections.

Numerous other objects of the invention will be apparent as it is better understood from the following description, which taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

For the purpose of illustrating my invention I have shown on the drawing a portion of a main shelf assembly 11 which provides a housing for an auxiliary rack 12. The rack 12 is adapted for support in the main shelf structure and to furnish support for shelf boxes or drawers 13 removably mounted therein.

The main shelf assembly 11, comprises a plurality of front and rear tubular uprights 14, each pair of which are connected by a vertical front to rear partition 15, front and rear bearer bars 16 mounted between adjacent uprights and shelves 1? extending be tween adjacent supports and supported at front and rear by the bearer bars to form vertically and horizontally aligned compartments (Fig. 1). The opposed sides of tubular uprights 14, Fig. 3, are provided with a plurality of spaced slots 21 of double T shape, that is to say slot 21 comprises a bottom relatively narrow portion 21, a wider portion 22 thereabove and a still wider top portion 22'. The narrow portion'21 is adapted to receive and support the end of a bearer 16 which is slotted for engagement therein. The portion 22 is large enough to receive a bearer bar which may be inserted therein endwise and forced down into engagement in the nar-.

row portion 215 of the slot. Each shelf 17 is provided with front and rear downturned flanges 18 and these flanges are bent inwardly at their bottom edges to providean inwardly disposed lip 19 the edge of'which abuts the lower outer edge of the bearer bar 16. The shelves 17 are adapted to rest upon corresponding front and rear bearer bars to pro- Vide a series of adjustable shelves within the structure, the spaces between said shelves forming adjacent compartments. By engaging bearer bars 16 in slots of suitable elevation, the shelves may be positioned at any desired height within the structure.

The main shelf structure 11 may be provided with a back plate 23, which is fastened to the rear tubular uprights 14 and serves to enclose the back of the shelf structure.

The rack 12 is adapted for mounting in the main shelf structure 11 between vertically adjacent shelves 17, and comprises a plurality of upright panels 31 front and rear bearers 34 engaging every panel of the unit to sup port and maintain said panels in spaced relat-ionship and shelf members 35 supported on corresponding front and rear bearers.

The outermost of the upright panels 31,

designated'by reference number 31, have front edges bent outwardly to form flanges 37, the edges of which are adapted to engage the opposed sides of adjacentfront uprights 14 of the main shelfstructure and thus support the rack more firmly within the main structure. The upright panels 31 extend vertically between the adjacent shelves of the main structure 11, and when supported on a shelf 17 extend upwardly and engage the lower edge of the supporting bearer bar 16 of the adjacent upper shelf. The upright panels 31are slightly taller than the upright panels 3lland have upper front corners notchedas at 36 to accommodate the lower portion of the upper bearer bar and the front flanged portion 19 of the upper shelf member. These notches provide a catchvengagement between the main shelf bearer bars and the rack. In order to position therack in themain shelfstructure it is necessary to raise the upper shelf bearer bar slightly in order to slidethe rackthereunder. When the rack.

is properly located upon its supporting shelf, the upper bearer bar is forced back into normal position, engages the notched portion 36 with a front and rear vertical series of slots 32. These slots are similar in shape to the slots 21 of the main shelf uprights, having a narrow portion 32 for engagement with a notched portion 34 of bearers 34 and

wider portions

33 and 33'. horizontally in the uprights having the narrowest portions 32 thereof forwardly disposed in the panel.

The bearers 34 are notched at each end for engagement in the slots of the end upright panels 31 and at'intervals' therealong for engagement with the corresponding slots of intermediate, upright panels 31. The. upright panels are thereby supported in spaced relation and provide partitions between ad-v jacent sections of the rack, each partition accommodates two shelf boxes side by side between adjacent uprights. I

tween adjacent upright panels 31 and are supported thercbetween by the correspond- The slots are positioned Shelf members 35 extend horizontally be- 3 ing front and rear bearer bars 34. The shelf members are provided'with downwardly extending flanges 41 bent therefrom, at front and rear edges on lines of bend 39 and arranged to engage the outer faces of the supporting bearers 34. Inwardly extending flange portions 43 are bent from flange portions 41 on lines of bend 42. The

portions

41 and 43 of the members 35 comprise pockets for receiving the front and rear bearers 34' and also embrace these bearers. Portions 44 of the body of'the shelf members are punched therefrom and bent downwardly to engage the inner faces of front and rear bearers to lock the bearers in the pocket formed by

flange portions

41 and 43. Portions 45 of the lower flange portion 43 of each shelf member are punched therefrom and extend downwardly to form loops 46. Each loop is adapted to engage the rear wall of a shelf box 13 positioned on the shelf below to prevent accidental withdrawal of the box insert completely from the rack. The stop also engages the front wall of the shelf box to prevent it from being pushed too far into the rack. lVhen it is desired to withdraw the box completely from the rack, it is drawn edge of the rear wall of the box whereupon the front end of the, box is lift-ed untilthe lower rear edge is clear of the front edge of V cut to proper shape and bent into box form.- 4 Each box comprises a bottom,. 51, side-walls forward until the stop 46 engages the upper 52 and end walls 53. The side and bottom walls are constructed from a single sheet of metal comprising a rectangular bottom 51 from which the side walls 52 are bent upwardly along parallel lines of bend 54. The bottom and side walls of the box are provided at each end with inturned integral end flanges 57 bent along lines of bend 56. The flanges 57 embrace rectangular end plates 58, and are secured ,theretoby spot-welding or other convenient means to form the ends 53 of the box. The upper edges of the side walls 52 and of the end plates 58 are bent inwardly and thence downwardly parallel therewith as at 59 to form folded edges 52 and 58 which increase the strength and rigidity of the box and improve its appearance.

The edges of the inturned end flanges 57 are offset at 61 to provide strips 62 parallel with and spaced from the end plates 58. The strips 62 form a rectangular pocket 63 at front and rear of the box, which is of doubleend construction that is to say if formed having identical front and rear ends. I A. handle 67 is secured in any convenient manner to the end selected as the forward end of the box. Pocket 63 at the forward end may be used to support a rectangular card 63 by which to identify the contents of the box. The uppermost row of boxes supported in the rack have no shelf members immediately thereover and hence no stop means corresponding to the loop 46 of the lower rows is provided. A stop member 64 is provided at the rear end of each box positioned in the uppermost row of the rack. This stop member is mounted in the rearward pocket 63 of the box and comprises a portion 65 adapted for removable engagement in pocket 63 and an upstanding portion 66 which projects above the top of the box and is adapted for engagement with the front bearer bar 16 of the main shelf structure to prevent the box from being wholly withdrawn from the rack. The box may be withdrawn from the shelf until. the stop member 64 engages the bearer bar 16 which prevents further withdrawal thereof as shown at 66 in Fig. 3. Accidental withdrawal is thus prevented. VVhenit is desired to remove a box entirely from the rack, it is drawn out until the stop engages the bearer bar. The front end of the box is then raised until the lower rear edge thereupright panels 31 in three vertical sections. Each section is divided from its adjacent sec tion by an intermediate upright panel 31.

Three rows of box inserts rest on shelf members 35 of the rack, while the lowest row rests directly upon the shelf 17 of the main structure on which the rack itself is supported. The rack comprises a suitably proportioned structure adapted to fit into a shelf compartment of the main shelf structure. ;The size of the rack may be varied to fit larger shelf compartments either by adding more shelves and increasing the height of the rack walls to accommodate the additional shelves or by adding shelves and side walls and extending the bearers to provide additional rack sections.

It is thought that the invention and many of its attendant advantages will be apparent from the foregoing description, and it will be apparent that various changes maybe made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the

form hereinbefore described being merely a preferred embodiment thereof.
