Fig S'a .Side View 0f 011 0f the fI'OIl 11p- For this purpose the groove is preferably of doverights in position ready for lowering to fit its tail shape.

The resultant dovetail tongue and groove construction is so designed as to provide appreciable clearance to accommodate ready endwise assemblage by dropping the spacers in place from above, in the course of assembling the shelving system.

Each crossbar is formed With a dovetail tenon 23 on each end to slidably engage the groove 21 on the correspondingbar. Y .L @jf-rig" lg The spacingofthe-molding lsections on shelves 4 provides rectangular notches 25 on thefront edge of each shelf to snugly receive the bar 6 of the corresponding front posts 2 respectively.-

The molding 15 is preferably of appreciably greater vertical depth than the thickness of the shelves 4 and serves effectually to brace the shelving against endwise distortion or swaying.` If desired this bracing may be supplemented' by di'- agonal members, as for instance tension wires.

meet opposite one'- pair yof Vuprightsfv'vi-ll beaver-'- lapped by a section whichis'continuousvat that point along the length ofthe shelving. Whenever a shelving system such as herein described is to be assembled, the-workman 'ar- 30' ranges first one pair of uprights 2 and then 'another, with the bottom crossbars 3 in place, and then he applies the' bottom shelf member 4. He

then applies a set of spacers 8, then a set of cross bars 3, and on these he places the next shelf, and so on until the top spacers'are in place.` He then inserts the'locking screws 10 andnally sets the top crossbars in place and places the cover member thereon. 'If the shelving is'very, tall, or seems for any reason to need'supplementalvv support to prevent tipping, fanyj desired or convenient fastening means may be'applied whereby it may be secured for instance "to 'an adjacent wall, as will be understood without further explanation.

If or whenever for any reason it isdeslired to dismantler the shelving, as for instance if it is to be put in storage or moved or set up ,in a different place, the reverse operation is followed., Whenever the shelvingr capacity needschange, the shelving may be either lengthened; or shortened by adding or removing longitudinalsections orv bays at one endorthe other. ,Y

In short, this ready-,set-up; and. knocflr--ydow-zn.`

AMore in detail, the stepped shelvingfsystem 41L comprises a plurality of steps Yor stages, namely, a

f bottom stage 42, a middle stage43, anda top' by crossbars 51.

stage 44, diminishing in depth from back to front in the order enumerated.

Taken as a whole this embodiment comprises a mutually spaced series of back uprights 46 common to all three stages. These stages are mainly similar and differ appreciably only in dimensions. The bottom stage or section 42 comprises a series of mutually spaced uprights 47, the middle stagea similar series of uprights 48 and the top stage a series of uprights 49.

The front and back uprights of the bottom stage are connected in pairs at their lower end This stage includes shelves 52 separated by upright spacers 53. Crossbars 54 'are provided for the middle and top shelf of this stage, the bottom shelf resting on the deep floor bars 51 which are secured by screws 51. Upright partitions 55' are mounted interchangeably between the front and back spacers 53, the latter being longitudinally grooved therefor, as shown in Fig. 7.- Back closure panels 56 are also provided, asshown in Figs. 7 and 8, the back uprights 46 being laterally grooved longitudinally at 57 to accommodate interchangeable mounting of said panels. The members 46 though shown composite may be formed integrally as in Fig. 15 where the back upright 46 has lateral grooves 57' and a front mortise for the crossbar ends and spacers. Thev top shelf member 61 of the bottom stage projects forwardly somewhat and is provided with lz a card molding 15, as are the lower shelves 52.

The middle 'stage 43 comprises partitions 62, upright spacers 53, crossbars 63, shelves and back closurel panels 56 arranged substantially as in the bottom stage. The lower ends of the front uprights 48- are provided.- with semi-dovetail tenonsv 65 to iit in corresponding mortises 66 in the shelf 61. The mortises are large enough to admit the tenons freely and are so positioned that when the upright is pushed forward horizontally, it is eventually locked in place by the partition 62 and spacer extensions 53'.

vThe top shelf 67 of the middle stage also projects forward somewhat and is provided with anv inclined card molding 18. It is also formed with a mortise, substantially as in shelf 61, to receive the front post 49 of the top stage.

The said top stage includes crossbars 68, partition 69, uprights 53 and shelves 70. The top shelf 71 is provided on its front edge with an inclined card molding 18. y

This embodiment is assembled, one stage at a time, beginning at the bottom. The crossbars, spacers and shelves are dropped into place vin due order as the work progresses, as will be apparent. f

Referring to the further modification, shown l by Figures 12, 13 andv 14, stability is imparted to Itmay bev noted thatthe. shelf; boards 14 are.

a tall system of shelving by uniformly inclining its front side backwardly somewhat toward the top, instead of stepping the same as in Figure 8.

In this construction, the system of shelving 75 is of somewhat simpler design than that in Fig. 8 and comprises mainly a series of mutually spaced back uprights 77 and a corresponding series of inclined front uprights 78 in combination with the bottom crossbars 79 and a set of crossbars 80 ranging from long at the bottom to short at the top, together with corresponding shelves 82 ranging upwardly from wide to narrow, and appropriate front and rear spacers 84 and 85 to support the crossbars 80. This embodiment 75 may be made. either with or without partitions and back walls.

This embodiment may be assembled ilat on its back and then raised to its normal position. The back uprights are first set in place and then the crossbars, shelves and spacers are arranged. Finally the front bars are threaded into place endwise, from the foot toward the top.

Although this invention is variously illustrated, it is to be understood that some of the details set forth may be altered or omitted without departing from the spirit of the invention as defined by the following claims. Although a true dovetail joint is considered preferable for general use, it is to be understood that this term as herein used is to be construed broadly to include any form of interlocking tongue and groove adapted for the purpose indicated.

I claim:

l. A system of knockdown shelving comprising a series of pairs of back and front uprights, crossbars connecting the uprights of each of said pairs, shelves resting on said crossbars of corresponding elevation respectively, vertical spacers interposed between said crossbars at their ends, partitions disposed connectively between corresponding back and front spacers, and back panels disposed connectively between adjacent back uprights and between adjacent shelves, said partitions and uprights being tongue and slot connected slidably to said spacers, said uprights being likewise connected to the crossbars in mutual tie relation and said back panels being tongue and groove connected slidably to the back uprights.

2. A system of shelving of stepped upwardly receding design including a vertical series of stages, each of less depth from back to front than the next inferior stage; said system comprising spaced back uprights extending from top to bottom; and each stage comprising a set of spaced front uprights, crossbars connecting same to said back uprights, shelves resting on said crossbars and front and back vertical spacers between crossbars to support the superior shelves, said uprights, crossbars and spacers having vertical tongue and slot engagement for assemblage and knockdown facility; and each front upright having tenon and mortise engagement with the next inferior stage and means to lock engagement thereof releasably.
