T all whom it may concern:

Be it known that I, Amit-nr C. Tonnen., a citizen of the United States, resident of Grond Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Metal Shelving, of which the following is a description, refereneebeing had tothe :iccornpenying drawings, which area part of this speciication.

support and may be easily This invention relates to improvements in metal shelving and more perticularly'to .ad-- justable shelves andA their support.

One of the objects of this invention is to I form shelves and their support of commer-` cial angle and sheet steel in which the shelves are adjustably connected .to their erected or changed to suit different requirements. w

A further object ofthe invention is to provide a unit system of shelving coi'niprising an installation which een lie quickly extended with additional parte, and when necessary to introduce changes. the parts een be quickly taken apart and reassembled to nieet different requirements Without dem age to -the equipment.

A further object of the invention is to provide a system of shelving in which the shelves are interchangeable end the support is provided with inea-hs wher-hy the sl lv may be easily connected to or di from the hack portion of the supp t.

A further object "of the invention is to provide a system of shelving constructed of nieta-l in which the shelves ere reinforced so they will stand the strain of`heavy loads wwithout bending.

A, further ohject of the invention is ,to provide a system of `shelving in which the parte are 4strong and durable and may be manufactured at a minimum expense.

W' ith the above, and other objects in view.

the invention consists of the shelving andA its parts und combinations es set forth in the clainis, and all equivalents thm-'noti ln the accompanying drawing in1 which the same reference characters indicate the same parts in all of the views Figure 1 is a front view of two sections of the improved shelving, parts broken away and otherparts `being shown. in section; 'verse sectional Fig.A t;

Fig. 2 is a transvieiv taken on line 2-2 of 3-3 of Fig. e; and Fig. Il is an inverted "Figu 3 is a similiir view taken on line y' horizontal sectional View taken on line i4-4 of 'Fig'. 1.

Referring to indicates the sheet steel back of the shelving support to which are connected, preferably by bolts, the outer end uprights 7 and the center or intermediate upright 8. The end uprights are formed of sheet metal plates reinforced along their frontend rear inner vertical edges by angle bars 9 and 10y respectively. The front and rear vertical edges of the intermediate uprightS :1re also reinforced by angle bers 11 end ll which ere riveted to both sides plate. rights are rigidly connected to the sheet nietal hack by 4`bolts, as before described, which extend through seid back and through the legs of the rem angled reinforcing bars extending parallel thereto.

The haelt plat-e end the legs ofthe `singled reinforcing hers extending parallel theretov with a `plurelity of forwardly end upwardly extending tongues or catches 13 andl which are cut and punched' out of the 'respective parts to form shelf ysups. The tongues or catches of the rein- =cizrg hers are positioned in horizontal elinenient with the tongues or catches of the haelt plate and the upwardly extendingportions of the letter tongues are positioned in vertical elinement with the upwardly extending portions of the tongues of the reinforcing onrs'to engage the rear depending flanges ofthe removable and interchangeL ahle shelves l5. These shelves are formed of thick plates of sheet steel having dovvnwai-diy depending side, front and rear flanges 16, l? end 18 respectively to reinforce the same and to provide means for attaching seid shelves to the supports. The

the drawing the numeral 6 shelves are further reinforced at the front' of the front and, rear` The shelves are. of sucient Width to en rear legs and the back and bind gage and extend between the front and rear .legs of the front and rear uprights and when so positioned the rear reinforcedi'ianges of the shelves hook over the catches of both the said shelves to said parts. The shelves are securely fastened to the end and intermediate up-v rights by means of bolts 21, 22 and 23 which extendthrough registering apertures provided in the depending flanges and the uprights., The apertures are in--relative alinement with the horizontal lines of catches in order toy provide for placing the shelves in horizontal position. .The apertures 24: of, the side flanges are in the form of elongated slots to insure correct registration and, to compensate for slight differences due to manufacture. The bolts 23 are of sufcient length to extend through thel side flanges of the shelves positioned' on opposite sides of the intermediate upright. The front and` rear end portions of the side iianges of the shelves are cut away to form offsets or recesses 25 in the shelves to accommodate the side flanges of the angle bars forming part of the end and intermediate uprights.

In erecting the shelves the uprightsare bolted to the back portion and the shelves are hooked over the projecting catches. The end and front iianges of the shelves are now bolted to the uprights by passing bolts "through the registering apertures of the flanges and the uprights and threading nuts to the ends thereof until the parts are clamped firmly together to forni a rigid structure. The provision of the catches on the rear portions of the support and the bolts on' the sides land front thereof provides for easy accessibility in removing lthe boltsto change the shelves.

The reinforcing strips connected to the shelves serve to strengthen the shelves and 'prevent warping or bending while under strain.

From the foregoing description it will be seen that the shelving is strong and durable and is'very simple in construction and may be easily erected.

What l claim as my invention is:

l. A shelf, comprising a plate of sheet metal lhaving one of its edges bent at an angle to the plate land overlapped upon the bent portion to form a flangeof double f thickness, and a reinforcing strip of angled metal'fastened to the plate with one of the angled portions of the strip extending beform anges of double thickness and `also having its end edges bent atf an angle to form end flanges, `and reinforcing strips of angled. and channeled metal fastened to and extending along the front and rear edge portions of the'plate with the :,mgledpor-V -tions of the strips extending between the overlapped portions of the plate edges.

4. Shelving, comprising a back portion provided with forwardly and upwardly pro?v jecting catches, end and intermediate uprights forming angled reinforcing bars eX- Aand overlapped'upon the bent portions to tending along their front and rear edges,

said rear edgebars being rigidly connected tol the back and provided with projecting catches, shelves formed of sheet metal plates and having theirfront-and rear side edges bent downwardly at an angle and overlapping upon the bent portions to form flanges of double thickness and also having` their end edges bent at an angle to form end flanges, reinforcing strips y of angled and ...channeled metal fastened to and extending falong the front and rear edge portions4 of the plate with the angled portions ofthe strips, extending between the overlapped portions of the plateedges, said rear edge flanges off the shelves engaging the .projecting catches of the back and the reinforcing bars,

the shelves adjacent thereto and ositioned bolts extending through the intermediate upright and the end flanges of loo on each side thereof, and other bol s binding v the flanges adjacent tothe end uprights thereto.

In testimony whereof, I mysignaj l ture, in presence of two witnesses. f f
