In constructing a rack unit with the dividers 11 and plates 26 above described, it is only necessary to provide a pair of divider plates 11 for the sides, a pair of lates 26 or the top 12 andbottom 13, a thir plate 26 if it be desired to provide a back 14, and such by slidin .ment wi 'side,flanging 27 of'the top plate 12projects' other plates 26 as may be-required for: the shelves 15. The top 12,-bottom 13 and'dividersll constituting the side walls of a unit may be connectedin any convenient sequence the 'top and bottom in interengagethe spaced dividers so that the downwardlyinto the spaces between upper rows of louvres'22 atthe same level, and the inside faces '21 of the dividers and the side flanging 27 of the inverted bottom plate 13 project upwardly inside the bottom rows 24 of reversely projecting louvres. If the top 12' and bottom 13 be applied'to the extreme top and bottom rows of louvres of the side dividers, the up er. face or surface of the top 12E'underlies an is-embraced by thetop side ange's 19 of the dividers and the lower face or surface of the bottom 13 rests upon the bottom side flanging 20. Whenever a back 14- 's employed for the rack unit, one of the plates 26 is positioned with the bulb flanging end 28 lowermost and is turned so'that the side flanging 27 will project forwardly of the unit and inside the inner faces 21 of the divider plates. The back 14 may be slid into place by lowering it until the bulb flangin 28 is positioned forwardly; of and within t e upstanding end flanging: 29 of the bottom 13, and the end flanging 29 of the back rests upon the upper surface of,

the-top 12 and the forward inside face} of the ca acityofthe'rac'k'unit, maybe applied at the evels permitted between the toplandbottom of the rack unit.

by the. rows of louvres [The shelves may bera-pidly applied or re- I e illustrative moved by sliding the interengaged side flang- I l ing27 within and relatively to an two rows of louvres 22 located at the same evel at opposite sides of the rack unit. When in posidown structure in which the parts may be rapidly assembled or adjusted to various requirements, without the employment 0 {any extraneous fastening devices whatsoever. Moreover only three structural- 1y different types of parts are required to provide a unit of any predetermined dimensions having a wide capacity for various adjustments of shelving. These parts are the two dividers which differ from each other only in that the louvres 22 and 24 are pressed reversely from the plane of the dividers to provide the right and left sides for the rack unit, and the flanged plates 26 all of which are alike and may be employed for either top, bottom, back, or shelving. Although extremely cheap to manufacture because of the small number of parts, all of which are made of sheet metal by relatively simple factory methods, the units when assembled are strong and durable and the parts remain permanently in adjusted position. The bulb flanging 16 and '28 at the front edges of the dividers, top, bottom and intermediate shelves, provide smooth, rounded surfaces, which eliminate-sharp corners and avoid tearing of the clothing, or possible injury to the articles, in depositing them on or removing them from the shelves.

Such rack units have one important use as shelving under ordinary wooden store counters, for carrying reserve stocks of the articles displayed upon the counters, They may be assembled readily in units with the desired length of shelving and the shelving may be adjusted rapidly at levels to suit the requirements of the articles stored in the racks. 4

It is thought that'the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arran ementof the parts without departing from t e spirit'and scope of the invention or sacrificing all of material advantages, the form 'hereinbefore described being merely a ferred embodiment thereof. Moreover, it is not'indispensable that all 'featuresof the invention bev used conjointl as they y be the a k e the an fl n n 2 time:

advantageously employe in; various subgcombinations and other combinations.
