,ALBERT H. LEVENE, OF PHILADELPHIA, PENNSYLVANIA.

ADJUSTABLE SHELVING.

Application filed September 13, 1919.

To all whom t may concern Be it known that I, ALBERT H. LEVENE, a citizen of the United States, residin at Philadelphia, county of Philadelphia, ,tate of Pennsylvania,have invented a new and useful Adjustable Shelving, of which the following is a specification.

@ne of the main objects of my present invention is to devise a novel construction of shelving wherein when shelves on the opposite side of an upright are in horlzontal alinement the locking members or chps employed on opposite sides of the uprightwill pass through each shelf into the upright, the construction being such that the shelf on one side of the upright is capable of'independent adjustment or removal without affecting the alined shelf on the opposite side of the upright. u

With the above and other objects in view as will be hereinafter more clearly set forth my invention comprehends a novel construction of adjustable shelving in which the shelvesl are capable of adjustment in order to eiiect their rearrangement in accordance with the character of the material to be stored.

llt further comprehends a novel construction of shelving in which the uprights are provided with a plurality of rows of slots arranged in spaced relationship. The shelves are provided with a novel construction and arrangement of slots to register .with predetermined slots of the rows of slots in the upright and locking devices are employed having means to pass through a shelf and into the upright, the construction of such locking devices being preferably such that each device will have a locking member to pass through a slot ,of each row so that any rocking or wabbling movement of the shelves is positively prevented and the shelves Vare securely locked with respect to the uprights.

lt further comprehends a novel construction et' shelving which lis constructed in such manner that the same shelves and upright may be employed 'for either a bolted or adjustable type construction so that the shelves and upright will be standard for both types of construction. lt' further comprehends a novel construction and arrangement of uprights, a novel construction of shelves, and a novel construction of clips which have locking t nes to extend latorally through the ein. es and upright and Specication of Letters Patent.

adapted to interlock with the upright when the clips and shelf are moved a short distance relatively to the stationary upright.

It further comprehends other novel features of construction which will hereinafter more clearly appear in the detailed description of my invention.

For the purpose of illustrating my invention, I have shown in the accompanying drawings a preferred embodiment of it. It is, however, to be understood that the va clous instrumentalities of which my invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangement and organization of these instrumentalities as herein set f orth.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings,

l designates the uprights which are provided at their forward ends with 'flanges 2 of any desired construction. The uprights are provided with two lines of slots 3 and 4, respectively, and with a single line of bolt holes 5, preferably positioned between the slots 3 and 4 and, as illustrated, the slots 3 and 4 and the bolt holes 5 open into each other but this is not necessary in all cases arising in practice. It is, however, desirable, from the standpoint of manufacture, to have the bolt holes open into the slots since the slots and the bolt holes can then be readily formed in a single stamping operation, as will be understood by those skilled in the art.

The slots 3 and 4 formed in the upright are lpreferably disposed in parallel alinementand are preferably of the same dimensions.

6 designates a shelf on one side of the upright 1 and 7 designates a corresponding shelf to be used on the opposite side of an upright 1. Each shelf has its front wall reinforced by means of a reinforcing bar of any desired type such as for example a channel 8 around which the material ofthe shelf is bent in the usual manner, as will be understood by reference to Fig. l. `The ends of each channel 8 are bent rearwardly, as indicated at 9, see Figs.. 1 and 8. One line of shelves as for example the shelves 6 see Fig. 5, is provided with' two lines o slots 10\and 11, respectively, and a single line of bolt holes 12. The slot 11 is of the saine width as the slot 10 but is made a little longer and extends through the bottom of the shelf fiange. The juxtaposed lineof shelves, as the shelves 7, are provided with two lines of slots 13 and 14, respectively, and a single line ofboltholes 15. The slot 13 is of the same widthvas the slot 14 but is preferably slightly longer than the slot 14 and extends through' the bottom of the shelf flange. 16 and 17 represent, respectively, a novel construction of clips which are employed. it being seen that on account of the enlargement formed by they channel' 8, it is necessaryto offset the clips 16 more than the clips 17 while the clips 16 have to accommodate the upwardly deflected portion 18 of the side flange 19 depending from the floor of the shelf.

I will first explain the construction of the clip 16 reference being directed more particularly to Fig. 7. Each clip 16 is provided with an offset 20, therebyk forming a seat 21, an upper extending portion 22 and a downwardly extending lower portion 23, such portions having facesl conforming to the juxtaposed faces of the shelf and upright. Near the upper end of the clip 16, I provide a laterally extending locking tongue 24 having a downwardly deflected hook forming extension 25 at its free end. In proximity to the tongue 24, I provide an aperture or bolt hole 26. ()n the downwardly extending portion 23 of the clip, I provide the laterally extending portion 27 which terminates at its forward end in a downwardly extending hook forming portion 28. In proximity to this laterally extending tongue 27, I provide through the portion 23 a bolt hole or` aperture 29. I have preferred to illustrate the locking tongues 24 and 27 as projecting from opposite edges of the clip but it will be apparent that they would perform the same function in many respects if they extend from the same side of the clip.

The clips 16 are provided withvone or more reinforcing ribs 30 of any desired formation. The clips 17 conform substantially in construction to the clips 16 except that they are not offset to the same extent. Each clip 17 is offset, as at 31, and near its upper end isprovided with a locking tongue 32 extending laterally from it and 4terminating in a hook forming portion 33. A bolt hole 34 is provided in proximity to the locking tongue 32.

Near the lower end of the clip 17, I provide a laterally extending locking tongue 35 which terminates insa hook forming portiony 36, and a bolt hole 37 is formed in proximity to the locking tongue 35. The locking tongues 32 and 35 are preferably projected from opposite edges'of the clip 17. It will` be noted that when the yholes in the flanges 19 of the shelves on opposite sides of the upright 1 are brought into register, the longer slot in one shelf is diametrically opposite the longer slot in the other shelf. Each channel 8 is provided with two rows of slots 38 and 39, respectively, as will be understood by reference to Fig.`3, and with a bolt hole 40, see F ig. 8.

rI lhe manner in which the shelves are .secured with respect to the upright 1 will now be readily annarent to those skilled in the art and is as follows When it is desired to secure a shelf in place, or to adjust its position with respect to the uwifrht. the operator brings the shelf into such position that the slots 10 and 11 or the slots 13 and 14 will bein register with the slots 3 and 4 of the upright. The locking clips 17 are then placed inposition so that the locking tongues 34 and 35 pass through different slots, as will be understood by reference toFigs. 1 and 2.

It will be understood from Figs. 1 and 3 that the locking clips 16 interlock with the shelf and the upright in a similar manner lexcept that their locking vtongues pass through apertures in the channel beam. As soon as the clips are in position the shelf and the clips are lowered so that the hooks 33 and 36 of the clips 17 and the hooks 25 and 28 of the clips 16 will secure the shelves in proper assembled position with respect to the upright.

Special attention is directed to the man- Lessen are to be located in the same horizontal plane they are assembled in the manner seen in Figs. 1, 2 and 3. From this it will be seen .that the locking tongues at the upper ends of the clips pass through in different directions the diametrically located slots in the shelves and in the upright while the locking tongues of different clips pass through -diainetrically located slots in theviipright.

-By such construction any lateral play of the clips with respect to the u right is prevented and the shelves are rigi ly secured in their adjusted position so that under load they will retain the position in which they have been adjusted. Each bracket is preferably provided with a locking tongue'to engage both lines of slots, one in a shelf and one in an upright'.

In so far as I am aware, I am the irstin the art to devise a'locking clip or bracket such as I6 or 17 provided with laterally eX- tending locking tongues which pass through the shelf and into the upright to interlock with the upright when the shelf is lowered and in all cases the locking clip or bracket may be inserted or removed without the necessity of employing any tools. I have preferred to show the locking tongues located in such a position that one is located above they other but these locking tongues may be brought nearer together or located in the same horizontal plane or presented from vthe same edge of the bracket instead of from opposite edges and still be within the spirit or scope of the invention. It will also be apparent that the line of bolt holes may be dispensed with in many cases arising in practice and only the two lines vof slots employed. If the bolt holes are employed, they do not necessarily have to open into the slots. These bolt holes are simply an accessory which may be employed in order to enable one to elimi nate the brackets when a permanent type of shelving is desired as the brackets are more expensive than the bolts. The slots in the shelves are preferably slightly wider than the slots in the upright and the locking tongues have a snug fit in the slots of the upright to prevent any rocking or lateral movement. The locking clips or brackets are preferably stiifened "especially Where they are bent or offset to support the channel and they are preferably also provided with any desired type of ribs to effect their reinforcement.

It is also within the scope of my invention to construct the shelving in such a manner that the bracket does-not have to be arranged vertically to be removed but can be removed by a horizontal sliding movement.

It will be apparent from the foregoing that inaccordance with my present invention when the shelves on opposite sides of the upright are arranged in horizontal alinement any shelf on one side of the upright can be removed or adjusted without aecting the locked condition of the shelf on the opposite side of such upright.

It will further be apparent that while my present invention relates more particularly to shelving which is adjustable if it is desirable to have the shelving at any time made more rigid all that it is necessary to do is to insert a bolt through the bolt holes and affix nuts to the bolts.

It will be apparent that while I have shown my present invention asvapplied to shelving, it is vnot limited thereto in its broad Y and generic application but is intended to cover any construction wherein two or more members are locked together in the manner herein shown and Ywherein when an inner and 'outer and an intermediate member are employed. one outer member or inner member may be removed independently of the other and without affecting the locked condition of the other by simply removing the clips on one side of the intermediate member and it is to be understood that my claims to such features are to receive the broad interpretation to which a generic invention is entitled.

It will now be apparent that I have devised a novel and useful construction of adjustable shelving which embodies the features fof 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 a preferred embodiment thereof which will give in practice satisfactory and reliable results,`it is to be understood that such embodiment is susceptible of modification in various particulars without de 'arting from the spirit or scope of the invention or sacrificing any of its advantages.
