Application `le'd November 1,-1923. `Serial-N0.6"?5L991.

This invention relates to shelving and more particularly to sectional shelving used for supporting and storing tools, machine parts, records, etc.

Shelving of this nature is shipped from the factory in lniocliedfdown `or disassembled condition, the interlitting elements, making it up, being fabricated in such `a manner` that the shelving may be assembled anderected at `place of use by relatively unskilled worlrmen and with minimum effortA In order that shelf elements of standard formand dimensions may be adaptable to the various requirements of different users, which requirements, of course, vary acc-ord ing `to the `nature of the service to be pen formed by the shelving, it is necessary that the shelves be vertically adjustable to vary the clearance between them, and that the shelvingbe `capable of erection in sections of` varying number, which number may `be changing Conditions.

To comply `with the above, the shelving r elements must be` detachably joined rather than permanently bonded, and the non-per-` manent nature of the joints renders it difficult to `provide an assembled struct-ure having the requisite degree of rigidity a`ndstability.

Therefore it is among the objects of my invention `to provide an economical and easily assembled form of sectionalshelving having the qualities of adjustability, adaptability to various situations, and of` little weight consideringthe load supported; and also a structure wherein the elements are made up, arranged and adapted to coact with one another in a manner to insure the proper rigidity and stability to the erected structure, and wherein the stresses and strainsarising from shelf loads are transmitted tothe vertical shelf-supporting members and by them resisted.

In general, I accomplish this by the use of removable corner clips adapted to clamp shelf-end flanges to uprights arranged at each corner of a. shelf unit, and providing the standards, clips and shelves with coacting portions which tie the structure together in a 4manner to stiifen it as a unit against Weaving or wrecking, and also to stiflen the individual members to increase their .resistance to iexure, etc.

The invention lis applicable to shelving of either closed end `or skeleton type, as will be apparent from the following detailed .description in which I will point out further features 'of novelty andobjectsof the invention. Reference will be had to the accompanying drawings, in which:

y I havez shown and will hereinafter describe my invention as .particularly applied to the closed end type of shelving wherein the end `members 8.of eachshelf unit or rack are made up of` vertical partition plates 9 welded or otherwisesuitably securedto the front and rear ,uprights or standards 10 and 10', respectively.` In this type of shelving the partition platesserve tolaterally space the uprights andto `laterally stiffenthe rack structure,but I` may apply the invention with equal advantage to skeleton `type shelving rwherein. the partition plates are omittednd the horizontal shelf forms ythe soleconnection between the front and rear uprights to laterally space and brace them.

`In connection with the following description of the various elements and their rela tive arrangement, I will 4point out certain coactions between them whereby certain outstanding results are obtained, but I will not attempt to mention all of the beneficial results so obtained. Therefore, I donot Wish it to be inferred that I have here exhaustively described all the possibleactions and` reactions occurring throughout the structure Whenit is inloaded or unloaded condition.

While uprights lOmay be` of any lcross section whiel'r will give the member the desired strength and present proper attachment surfaces,I prefer to utilize T-irons for this purpose asY they `have the quality of being exceptionally strongand rigid, al-

though of relatively little weight, and present exterior surfaces which are especially well suited for the attachment of fiat plates and flanges. Each of the four uprights, there being one at each corner of the rack, is provided with vertically aligned and equally spaced apertures 11, there being, of course, registering apertures in the partition plates.

Beneath each shelf corner is a clip 12, which will now be described in detail, al-

though the reason for certain of the peculiarities in the conliguration of the clip will be left for later discussion.

Clip 12' consists of a shank 13, carrying a wedge 14 at one extremity, the underside of the clip opposite the inclined face of the wedge preferably being flat and presenting a clamping face 15. rhe clip is apertured at 1G, whereby a bolt 17, extendingthrough one of the apertures 11, may be utilized for removably holding the clip to an upright and for drawing the clip into clamping relation with said upright, it being noted that the face 15a angles away from face 15 in order that the end of the shank may bear on the upright when face 15 is held spaced from and substantially parallel to said uprights by the interposition of a shelf flange, as clearly shown in Fig. 3.

The wedge face 18 inclines upwardly and inwardly from the upper extremity of the clip and is transversely convexed about the longitudinal axis of the clip, or, in other words, the wedge is of variable plano-convex cross section along its longitudinal axis. Prefe "ably, and as clearly shown in Fig. e, the degree of convexity is relatively small at the point of the wedge but progressively increases from the wedge point towards and to the wedge heel 19. The reasonl for these peculiar characteristics of the clip and an explanation of certain variations in the clip configuration which may be made without departing from the scope of my claims, will be discussed to better advantage after the following description of certain elements adapted to coact with the clip. Y

Extending laterally from clamping face 15 is a pin 20, the distance between the center of this pin and the center of aperture 16 being equal to center distance between apertures 11 in

upriglits

10 or 10, so the clip may be shifted vertically along its re spective upright to bring aperture 16 and pin 2O in register with different pairs of adjacent apertures in the uprights.

Shelf 21 has depending end flanges 22 with openings or notches 23 alongy their lower edges, the flanges being adapted to be lowered between uprights 10, 10n and the clamping faces on the corner clip when the shelf is lowered into operative position on the uprights. Notches 23 are spaced apart so they register with laterally spaced pins 2O as carried by front and rear corner clips, the coaction between notches and pins serving to guide the shelf into approximately proper lateral position with respect to the upright. rlhe shelf comes to rest with the `lower flange edges, which define the notch crotches, in engagement with the top of the pin. Since these pins are supported at one end by clips 12 and at the other by

uprights

10 or 10*l (due to the passage through and lit of the pins in apertures 11), and since the points of pin support are close together, it will be seen l have provided a very desirable form of supporting means between uprights and shelf. By taking up bolts 17, clip 12 may be drawn toward the upright to securely clamp the shelf flange thereto, whereupon the shelf and shelffflan'ge act as stifleners between uprights.

When used in connection with skeleton7 construction, the coaction between pins and notches and the clamping action of the clip on the shelf flanges,` permit the shelf to serve as a spacer between uprights, no other spacing means then being necessary.

When two shelf units are to be arranged side by side, a single, centrally arranged member 8 may serve to support adjacent ends of shelves in the two units, and, when the shelves in the units are on the same level (as is true in Fig. 3) a single'bolt 17 may serve to clamp both the opposed clips. In this situation, 1 cut back the end ofthe pins to leave semi-cylindrical lips 20, the lips on the two opposed clip pin ends being complementary so they overlap shown in Fig. 8) to form, in effect, a single pin supported in the opposed clips and extending through and partially supported by the interposed uprights. The length of the pins and projecting lip are, of course, so proportioned that there is suflicient clearance between their ends to allow the clips to be (as clearly drawn tightly into clamping position without pin or lip interference.

Shelf 21 has depending and substantially coextensive side strips 211 which are bent back and beneath the shelf to form horizontal flanges 25, the edges of these flanges, in turn, being bent upwardly to form vertical flanges 26. Disregarding, for tl e moment, certain peculiar functions of lthe strips and flanges in coaction with other shelf elements, it will be seen that the shelf is materially reinforced by the marginal strips and flanges, and that said strips and flanges, in turn, are of mutual benelit as reinforcements. v

The ends 27 of horizontal flanges 25, and preferably the ends of strips 24e, are cut back with respect to the ends of the shelf to allow wedges 14 to pass between end flanges 22 and said horizontal flanges and flange ends 27 are cut in a manner lto be substantially complementary to aud engage the convex wedge Lacasse face 18 when shelf 21 is in operative position on the upright.` By yreason of the tapered nature of the upper end of the clip, it will be seen that the shelf may be easily lowered into position without interference from the clip, and, furthermore, that by reasonof the inclined face 18, the horizontal flange will shoulder against it in .spite` of slight discrepancies in the notch and pin sizes or locationi The ends 28 of vertical flanges 26 are preferably cut parallel to the inclined plane of the wedge, so, when the shelf is lowered into position, these endsengage and have a relatively large surface .bearing on the clip. The advantage of varying the degree of wedge convexity from end to end willnow be apparent. The relatively flat point of the wedge, that is, relatively flat as considered in cross section, makes it possible to more readily lower the shelf into operative position without interference between shelf and clip, while the increased convexity of the lower part of the wedge provides additional.` swell to form ample shoulder surface for the end of the `horizontal flange, and also gives a more sharply defined interlock between clips and horizontal flange whereby relative horizontal movement therebetween is more effectively resisted. In this connection it will be noted that the arcuate ends 27 of flanges 25 extend around both sides of the longitudinal axis of the wedge face, so, after clips l2 have been clamped tightly against the end flange, the coaction between clips and horizontal flange definitely positions the shelf with respect to clips and nprights, and indirectly stiffens the rack structure against `lateral weaving. Furthermore, any tendency of the shelf to flex laterally causes end 28 of the verticalflange, and the adjacent face of flange end .27, to press inwardly on the clip, and by this coaction between flanges and clips, such lateral flexure is resisted. I

At this point, I wish to make mention of the fact that the convexity ofthe wedge face need not be necessarily regular nor have the characteristics of a curve or arc. For instance, the sides of face 181night rise to a central point or ridge and ends 27 be provided with complementary V-notches, and still the clips and horizontal flange would coact and function as above. Therefore, all references to wedge face convexity, either in the description'or the appended claims, are to be construed broadly.

In addition to its general function of `a shelf reinforcement, horizontal flange acts as a tension member for shelf 21, so, when the shelf isput under load, said `flange tends towards elongation, but such elongation, and consequently the shelf flexure, is resisted by the engagement of flange ends 27 and 28 with the wedge face of the clip. The spacing of flange 25 an appreciable distance below the shelf increases the effectiveness of this method of shelf bracing.

The stresses and strains arising from loads on the shelf are thus transmitted to the up rights; and the bends between the shelf and its end flanges, which bends are relatively weak points ofthe structure and ordinarily called upon to bear such strains, are relieved from the detrimental effects arising from shelf loads.

By thus reinforcing and stiffening the shelf, the rigidity and stability of the ent-ire rack structure is increased. It will be apparent to those skilled in the art that I have provided a simple and effective method `of joining vthe shelf elements, and that the coaction between elements is such that the assembled structure is braced against horizontal, longitudinal, and vertical weaving and buckling.

I Wish to make the reservation that the drawings and description are to be considered as illustrative of and not as restrictive on .the broaderv claims appended hereto, for it is evident that certain changes in structure and design may be made without departing from the spirit and scope of said claims.
