Application filed'April 9, 1914. Serial No. 830,601.

To all whom it may concern Be it known that I, ADOLF Hnnnn'r, subject of the German Empire, residing at Niddastrasse 60, Frankfort-on-the-Main, Germany, have invented new and useful Improvements in Sheet-Iron Shelving, of which the following is a specification.

This invention relates to an improvement in the already known sheet metal shelving in which horizontal single-piece shelves are fixed upon upright single-piece supports passing through them and are lodged upon suitable shoulders on these supports at the required-height; and vertical side walls are inserted between the horizontal shelves, merely for inclosing and limiting the space, without materially aiding in the support of the load. In this construction, difiiculties are found in securing the shoulders on the vertical supports in a simple manner at the requisite height and also in obtaining in a simple manner a fastening and guidance of the vertical walls.

The known devices according to which sleeves with side rims are placed upon the vertical uprights or rolled-on sleeves are provided at the side edges of the vertical partitions, render diflicult the fitting of these sheet metal shelves in regard to the height thereof. 7

According to the present invention there is constructed a simple, resistant and strong sheet iron shelving, which can be adapted in a simple manner in its dimensions to the wishes of the buyer, by making use of tubes as the uprights, which tubes are provided with a longitudinal slot into which the vertical partitions can be inserted, after alternately placing the intermediate horizontal shelves upon the uprights so that conse-'' quently the horizontal shelves with theirload are supported immediately by the vertical As compared with the very difficult diminution of the distances between a the shelves in the shelving, hitherto existing, it is in the present instance only necessary to cut down the vertical partitions with the metal shears, or to replace them by fresh metal partitions easily obtainable.

The" accompanying drawing illustrates the invention as followsi Figure l'shows a portion of the middle of a set of shelving. Fig. 2 shows a trans- Verse section through a portion of the shelving. Fig; 3 shows the new shelving in front elevation. A

In these figures a denotes the one-piece horizontal shelves, which by means of holes perforated at the edge are placed upon the uprights I). These uprights are composed of tubes which are provided with a longitudinal slot. Between each pair of shelves there are inserted vertical partitions 0 so as to be held in the slots of the uprights, so that the single-piece shelves at are supported by these partitions 0 and are held thereby at the requisite distance apart. By this special construction, the shelving in spite of its simplicity possesses in combination with the metal backing or with flat iron stays at the back an extraordinary firmness and power of resistance even to very considerable weights. The shelves at can of course be constructed to correspond to the load for which they are designed, and they may be flat as shown in Fig. 1 or more or less bent as shown in Fig. 2.

In the construction illustrated in Fig. 2, the shelves a are provided at the ends with edges cl, 6, in order to be able toguide them at various places upon the slotted tubes 6 to increase the rigidity of the shelves. The rims in this, case can of course also serve to form molds. The shelving can obviously either be placed against a wall or be constructedback to back, or be provided with. a
