1.0 Claims.

This invention relates to shelving and particularly to supports therefor. Itisaprimary ob- -ject .and purpose of the present invention to provideia -very simple, practicalandiuseful shelving construction and support for adjustably carry ing '.horizontal shelves "between thevertical ends offcases or frames, whereby the shelves may be readily adjusted to a'large number-of positions andheld in any :position to which adjusted. It `isa 'further object of the invention toy provide a shelving rsupport construction-which may also be used to lock ashelf in a Iposition lto which ad-v justed, and prevent its vupward movement away `from'thesupporting element beneath, and, preferably, Ythe locking .meanswill .fbe identical with thesshelf carrying andsupportingmeans.

"Many other `objects and `purposes Athan those ,stated will be apparentas an understanding of the invention is had from thefzollowing description, taken infconnection withqthe, accompanying Fig. ,l 'is-a lfragmentary vertical ysection illus- .trating'theshelving support of -my-invention used with :a horizontally located;v shelf, vand also showingthemanner yin which the-shelf is Iheld against i vertical movement.

Fig. ..3 .is .-.a horizontal section .through one end ,ofthe shelvingstructure, showing a shelf support Eig. 4 .is ,a .longitudinal ,vertical section through the channel vmember which .is mounted upon ra vertical endof the shelving structure, and.upon which theimmediate shelf supporting elements are adjustably. carried, and

' Fig. 5`is avperspective .View of one of the shelf carirying'brackets, which also may be used above amshelf to 'maintain'itagainst upward movement.

*hi-ke reference characters refer to like parts in the -differentrgures ofthe drawing.

In `shelving two spaced-apart vertical ends I are provided-which -may be rconnected attheir lower ends Yby a base andat their upper ends 'by a-top cornice. fAt the inner-sides Aof the end members -I, and at at least two points between the lfrontfand-rear edgesof the ends I, a sheet metalU-shaped-channelis inserted in a vertical groove-made l"for its'reception, the channel being 4bent intoform `from a-singleplateof sheet metal, andihaving sides 2 Vconnected by a bendat 3. At the youter'edges of the sides 2, flanges 4 maybe turnedfoutwardly away from eachother. From :ber described, tongues v5 and '6 Vare struck inwardly asbest shown inFig. `4, the tongues-5 ex tending upwardly Aand vinwardly at an angle to .the vertical, and the ,tonguesf fromthe opposite yside extending downwardly and inwardly vas shown, whereby said tongues overlapeach other in spaced pairs, as illustrated in Fig. 4.

The shelving brackets `which are used are made 'from a single plate of Asheet metal into the form shown in-Fig. A5. Axhorizontal ledge I is provided, from whichlis an integral downwardly extending section .8. At `one edge ofthe section 8 a section 9 is turned at vright angles, ybeing cut away at yits upper portion soas not to reach to the upper edges of said section 8, and at its free upper corner the section `9 is continued in a vertical linger I0.

As vshelf "bracket of the character Ydescribed may .be inserted, as indicated in iFig. 2 into the space -between the sides 2 of the channel, the iinger I'D extending vertically back of two of the `overlapping tongues 5 and 6, while the lower edge of the section 9 bears upon the upper edge of `the nextlowermost tongue 5, as shown in Fig. 4. The section lies flat against the inner side of ithe end I of the shelving frame, with the ledge 1 extending horizontally therefromat right angles Ato and Vaway from `the inner side of ysaid end member I. With a plurality of thev bracket members carried bythe opposite end members 'I of the frame, having their ledges 'I al1 in the same horizontal plane, a shelf Il (Fig. 2) may be placed vthereupon and `be held and supported in .a horizontal position. If desired like bracket 4members may be hooked into the channel members in inverted position spaced upwardly from the supporting bracket members a distance equal to the thickness of the'shelf and the shelf insertedbetween the upper and lower brackets as 'illustrated in Fig. 2, which `will prevent the shelf from being inadvertently raised out of position.

With this construction also, by properly spacing the tongues 5 and I, a shelf such as -I I of wood and of the normal standard thickness of a wooden shelf maybe supported and locked in place as described, while a narrower shelf I2 of glass, as in Fig. l, may be supported upon the same lower brackets, but because of its reduced thickness of the glass shelf which is approximately one-half the thickness of a shelf of wood.

The construction described is simple, yet very practical and useful. In use it has proven very satisfactory.

It is to be understood that the invention is not restricted in use to supporting shelves. The same construction without change may be applied to cases or cabinets to serve vas adjustable drawer supports, the drawers. resting upon and moving over the ledges 1. There are various other places of use which will occur to those skilled in the art, and which have occurred to me, therefore, the invention is to be considered as comprehending all forms of structure and all uses of the structure such as come within the scope of the appended claims which define the invention.

I claim:

1. A construction of the class described comprising, a vertically positioned supporting member of channel form having vertical spaced apart sides, one of said sides having tongues struck therefrom upwardly and inwardly at an angle to the vertical, and the other of said sides having tongues struck therefrom downwardly and inwardly, whereby the tongues substantially engage against each other at adjacent sides, said tongues being spaced vertically in the length of the support, and a bracket of flat metal having a section to pass between two adjacent pairs of tongues, said section resting at its lower edge upon a lower tongue and having at its upper inner portion an upwardly extending finger located -behind the upper tongues, and said bracket including a horizontal ledge extending away from the support, as specified.

2. In a construction of the class described, a support having spaced apart parallel vertical sides, the depth of the space between said sides being greatly in excess of the distance between said sides, vertically spaced supporting means located horizontally between the sides of the support, a shelf supporting bracket having a flat vertical portion adapted to rest at its lower edge on one of said supporting means and to have a hooked connection at its upper portion with the next adjacent upper means, said bracket having a substantially horizontal ledge extending away from the support, and a second like bracket located in an inverted position over and spaced from the rst bracket, located between and connected with two of said spaced supporting means above the first bracket, whereby its horizontal ledge will be located over and parallel to the horizontal ledge of the iirst bracket, between which ledges the edge portion of a shelf is adapted to be placed, as specied.
