SHELVING CONSTRUCTION Applcationled September 30, 1931. Serial No. 566,034.

My invention relates to shelving, particularly of the type constructed of sheet metal. In some forms of shelving, the shelves aro supported upon uprights, and the structure is `left open at the back, or at the ends, or both. Such open structures are usually termed racks. In other cases, it is desirable to close the backs or the ends, or both, and this is done by employing sheets of metal, commonly called panels. Where a panel separates one unit of the shelving from another, it is frequently termed a partition. Sometimes the partitions are termed back walls or end walls as the case may be. The term pa-nel, therefore, denotes the use of these closure sheets in whatever situation they may be.

@ne object of my invention is to provide simple, rugged, and efficient means for holding the panels firmly in position, and particularly to hold them in close contact with the uprights.

Another object is to make it possible to assemble the elements in any one of a number of different positions, by means of the same clamping member. In other words, an object is to make it possible, by employing a single form of clamping member, to cause Y the panel to extend from the upright-in any one of three directions, i. e., to the right, to the left, or forward.

In its most complete form, it is possible, by the employment of a single form of clamping member, to clamp three panels to the upright, one extending in Vone direction lengthwise of the shelving, another in the opposite direction, and one at 'right angles thereto.

A fuitherobject is to provide a construction such that the panel will make very close contact with the upright, thereby strengthenin g the structure and preventing rattling` where used in industrial buildings or other places where the shelving is apt to be subjected to vibration. v

I accomplish these objects inthe manner illustrated in the accompanying drawing, in which:

Figure 1 is a fragmentary view of a por- 1lgiloi of shelving, showing the parts assem- Figure 2 is a plan section of the line 2 2 of Figure 1. In this particular assembly, there is shown the various positions in which th1L panel may be clamped to the upright; an

Figure 3 is a plan section similar to Figure 2 but showing all three panels uniting at a single upright.

Like numerals denote like parts throughout the several views.

`Referring to the drawing:

There is an upright 15 which, in the form illustrated, is, in cross section, somewhat like the letter B, It has a back 18, two end walls 19 at right angles thereto, two oblique section 21V integral with and extending obliquely from the end walls 19, and front sec-tions 23 Aintegral with thek oblique sections 21 and lying parallel to the back 18. There are also two parallel lflanges 25 integral with the sections 23 and extending at right angles to the back 18. They are spaced apart for accommodating between them the 75 panels 17 '.4 Thus in the form illustrated the upright has a double tubular section.` It has a back418 and two convex portions, each'including a more or less flatv oblique section 21.

In each oblique section 21, there are slots 27 which, in the illustrated form, are arranged vertically. They are spaced at regularv intervals and are capable of serving a dual purpose, one for holding the keys 51, which support the shelves 13, and the other for cooperating with the clamping members 73. The keys and the parts co-operating therewithform the-subject of a separate application filed by me on or about the 1st rday of August,`1931. v 90 The panels 17 are simply metal sheets of proper gauge to form back walls, end walls, or partitions in the shelving. They have apertures 67 spaced vertically atintervals corresponding to the spacing of the slots 27. They accommodate bolts 83 which also penetrate slots 71 in the clamping plates 7 3. It is these clamping plates, with their co-operatking elements, which embody Athe invention herein claimed.

CTU

The body of the plate is planiform and adapted to lie flatwise against the panels 17. Each plate has a flange adapted to engage the end walls 19 of the uprights 15. This is shown in plan section in 2. The flanges 75 are sligitly shorter than the vertical dimension of the slots 27 and, by preference, the body of the clamping plate is of suliicient height to carry two of these iianges 75. Hence theflanges, with their extensions, may be regarded as tongues extending from the body of the plate.

Integral with each flange 75 isa flange 77, which is bent obliquely s o as to form a channel adapted to seat on the metal at the vertical edge of the slots 27. Thus the 'clamping members 73 may be regarded asv fulcruming upon the upright at the edge of the slots. Each tongue has an additional flange 79 at the extremity which lli es within the upright, as does the flange 77, and seats in one ofthe inter al corners of the upright, as shown in `Figure 2. The parts are so proportioned that when the body of the clamping member is bolted closely to the panel 17, the extremity of flange 79 will be firmly seated against the upright, and the channel between the sections 75 and 77 will press closely against the metal at the vert-ical edge of the slot 27, and the panel itself `will be pressed closely against the upright. lt will thus be seen that the member 73 is an actual clamping member by which the panel may be clamped to the upright and iirmly pressed against it.

This prevents rattling andat the same time adds stiffness to the structure.

The internal rectanffular corners in the upright are symmetrical with respect tothe slots 27, with the result that the clamping members may be placed on the upright in any one of four positions.` Two positions are illustrated inl full lines in Figure 2. Another is shown in dotted lines in this figure, the panelsV 17 being inserted between the parallel lianges 25. rlfhus it will be understood that the clampingV member may be inserted in either one of two positions on either side of the median plane of the upright. lt will also be understood that by placing clamping'members at different elevations, they may occupy all of these various positions in a single upright without interferingvwith each other.

It will be observed that the clamping member hooks into the upright land yet does not extend through it as a whole. This avoids projecting ends, which are not only unsightly, but have a tendency to abrade the contents of the shelving'. Viewed from the front, the upright presents a smooth surface, except for the slots formed therein. It will also be observed that soflong as the clamping-member remains fastened to the panel, there is 'no way that the lelements can 'be taken apart, that is, no rway that the panel can be removed from the upright. Furthermore, it will be observed that the flanges on the clamping member interlock with the upright in such manner as to prevent shifting of the panel in any direction. Notwithstanding this, the clan'iping member may be removed and the panel be removed from the upright upon the removal of a .single fastening device, such as the bolt 83.

From the foregoing, it will be evident that as a result of my invention, the user has a full choice as to the number and position of panels which he may employ, and this by the use of a single form of clamping member. rlhe symmetry exhibited by the upright, and the shape of the clamping member relatively thereto, makes it possible to use a single form of plate and yet to place it in any one of four posin tions in the upright. Ilurthern'iore, as the clamping member fulcrums upon the uprght and bears closely thereon, and is capable of drawing the panel closely against the upright, there is no danger of rattling, and the structure is held firm and rigid.

That I claim as new and desire to secure by Letters Patent is:
