The' kembodiment Y of thel invention illus,-

trated comprises a sheet metal case or cabinet consisting of a top plate 1 having integral, depending, channel-shaped end flanges -2 and depending side flanges 3 which are fastened to the upright end walls 4? and 5 of the cabcal section on theline 3,-3

20y entary elevation of a g ai) inet as by screws. The cabinet may be securely fastened to the floor by an angle piece fixed to the end walls in any vsuitable manner and to the floor as by screws 31. The rear end of the vupright wall 4 is providedwith 5.3 an'inturned flange or attaching strip 6 and the front end `of the wall 4 is formed with an outwardly turned front wall 7, the end portion of this wallfbeing provided with a flange or outer wall 8 which extends parallel 4o to the end wall 4. A `reenforcing channel strip 9 is secured as by welding to the inside of the end wall 4 `and outer wall V8 for strengthening purposes. A s most clearly' indicated in Fig. 2, the metal o-f the'front wall 7 is stamped or otherwise forced'outwardly `to form a rectangular ridge or guiding projection 10 which extends the entire length of wall 4.v Y 1 In order to present a finished appearance Y 5.0 tothe ends of thegcabinet, a falseend orend a, 1924.- 'seriaiNof 749,417. `r i panel 11 closes eachiend of the cabinet and is provided withan. inturned end wall 12 which is welded` or otherwisesuitably. secured to an Vuprightreenforcing panel'13, the inturned flange 6 of the end wall; 4vbeing fixed nany suitable'niannerto the opposite face of the panel 13. rlhe front end of the end wall11 is provided with an inturned` flange 11a, ther corner thereof being rounded to eliminate sharp corners, andthis flange is secured in any suitablefnianner to a strip 14c which is preferably welded tothe front wall 7'.rv Secured to the top plate 1v as bybolting and extendingV from end to end of the cabinet is an upright facing Vstrip 14a of channel shape which gives a* nished appearance to the top of the stack. f

{Mounted on the lower lportionof the cabinet is a shelf 14, having an integral, dependel ing front wall 15, which is provided withlan inturned supporting flange 15a, and a depending flange 14b` at the rear end whichabuts i against the attachingflange 6 of theend wall i 4.- The sides o-f the shelf 14 are provided with integral'depending flanges 16 which engage tongues 17 struck up from the end walls 4. yIt will be evident that the bottoni shelf inay be readily attached toand detached `from the cabinetv andthe front wall 15 'gives la finished appearance vtothe bottom of the cabinet.

A central partition for the cabinet comaoY prises a front wall 7 a integral with parallel f upright side walls 5 and 5a, which have outwardlyturned flanges Stand 6b respectively,

serving'asl attaching strips foronc end ofthe t shelves as will be hereinafter described. y'A I reinforcing channel 5b is secured as by -weldy ing to the side walls 5 and 5a for strengthen- .ing purposes. To reinforce the flanges 6i" and .6b a strengthening panel 18 may be fixed as by welding to the back ofboth flanges. Suit ably formed in the front wall-Fis a guiding ridge 10a which is similar to the ridge 10 on the front wallof thezend wall 4 .and ex- 9 tends parallel thereto. .It will'be understood that any suitable 'number of partitions constructed as described maybe employed ac-k cording to the desired size of the cabinet.

v'Any suitablenumberv of shelves maybe supported in the cabinet and each shelf comprises a plate 19 having depending side flanges 20, the front end being provided with a channel-shape flange 21 which has-an upstanding lip 22 intermediate the ends of the flange adapted to begrasped to attach or detach the'shelf. As indicated in Fig. 5, the flange 21 extends outwardly a slight distance beyondthe side edges of the shelf and fixed as welding to the inside of the outwardly extending flanges-are blocks 23EL with which 'pinsor fingers 23 are integral, the lingers extending from the block toward the rear end of the shelf. `As indicated inlFig. the fingers 23 are inclined outwardly forming approximately an angle of 99o withV the flange 21, thisinclination not being great enough for .the lfingers to ,be damaged when the shelves are removed from the' cabinet and supported .on their side. The rear end of the plate '19 is formed with-a depending channel-shaped flange 24 intermediate the sides thereof, and the opposite end portions of the rear edge of the plate 19 are provided with Vdepending attaching flangesy 26.

In order to support Athesh'elves in the cabinet, tongues or ears 27 arestruck out of ,the

f metalV in the attaching flanges 6- and 6a. The

tongues or ears 27 are inclined upwardly and are arranged vertiea ly in spaced relation, a

ton gue onthe strip 6 being directly opposite from a tongue on the strip 6a. Formed in the front walls 7 and 7 a are apertures 28 which are also arranged in spaced relation, an aperture'in the wall 7 being directly opposite from an aperture in the wall 7a. It will be observed that a-pair of apertures 28 in the walls 7 and 7a are laterally offset from but in the saine horiz ntal plane as a CorrespendingV pair .of

, ments.

The shelves are attached to the cabinet by inserting thelingers 23 into a corresponding pair of apertures 28 in the walls 7 and 7, the rear end of the shelf Vbeing tilted upwardly for the flanges 26 to clear a pair of tongues 27in the same horizontal plane as the pair of apertures.- Byinclining the fingers 23 outwardly as indicated it is unnecessary to make the holes receiving them of exactly the same size but Athey arepreferably larger than the lingers. When the fingers are inserted into their respective holes they bind against the sides thereof, this fric-tional engagement not only holding the front of the shelves securely in posit-ion .but also holding the central partition and end walls together. rl`h ereafter the rear end of the shelf allowed to swing downwardly about lingers 23 as pivots to bring the flanges 26 intoengagement with the struck-up supporting tongues 27. It will be observed that the tongues 27 are sojshaped and positioned that a shelf resti-ngen a pair of tongues may be swung upwardly clear of the tongues thereahove. As attached the opposite edges of the front end of the shelf abut against the guiding ri 4 ges 10 and 10a which project a slight distance therebeyond thus to cover the sharp edges and give a neat appearance.

In order to detach the shelf the rear end is swung upwardly a sufficient distance to disengage the flange 26 from the tongues 27 so that the shelf may be moved horizontally to disengage the fingers 23 from the apertures 28. It will. thus be apparent that the end supports for adjustable shelves in cabinets of the type disclosed may be arranged to give any Adesired spacing for the shelves. The number and position of the tongues and apertures may be changed in accordance with the requirements to enable the shelves to be arranged in any desired relation.

To increase the depth of the cabinet the construction above described may be duplicated on the opposite side of the panels 13 and 18, an end wall la being fixed to the panel 13 in alignment with the wall 4l and a partition 202L being fixed to the panel 18 in alignment with the front partition. rlhe shelves 14 are supported in the cabinet after theV manner above described, and theends are closed by end panels 11a fixed to the ends of the end walls Al and 4a respectively.

An outstanding characteristic of the invention consists in the unique end supports for the shelves whereby liability of the Shelves being displaced by very heavy burdens is eliminated. IThe marked simplicity of these supports as well as of the shelves contributes materially to the production of an inexpensive cabinet. Another feature of the invention resides in the provision of indicators to enable corresponding supports to be-located in a simple manner, thereby overcoming ol jections to supports of a similar character which ordinarily require irlsome searching for cerrespondinglgly positioned supports. Another feature consists in the shape and position of tongues 27 whereby a shelf resting upon one pair of tongues may be swung upwardly past the tongues thereabove (see Fig. 8), thus facilitating the insertion and removal of shelves.

Although I have shown and described a construction of the cabinet or stack which is the best form known to me at this time, it will be understood that numerous changes iii details of construction and arrangement, and in selection/of materials may be made without departing from the spirit of the invention especially as defined iii the appended claims.V
