'In the accompanyingl drawings I have illustrated a section'al `shelving construction cdmi series f of Thisy member is shown to be formed of wood. or like material. and is provided w1th two longitudinal grooves a. which are arranged in outwardly divcrg ing relation. and which aie adapted to interlock with the outwardly converging locking flanges 6 of the supporting lia r or member 7. This member or har is formed of folded Sheet metal to provide an inner contacting pair of sides 8, which are formed with a vertically spaced openings 9. through which the locking pins 10 (not shown) are adapted to be passed for holding the horizontal shelf supporting members 11.

The horizontal shelf supporting members 11 are formed of foldedxsheet metal to provide sockets 12 and angular flanges 13. on which the wooden or other shelf sections are disposed. The flanges 13 are stamped to provide vertical locking lugs or tongues 14, which are disposed in contacting pairs, as shown in sect-ion in Fig. 12 and in plan in Fig. 2. Thev intermediate horizontal shelf supporting members 11 are connected at their rear ends to the vertical supporting member or bar 15, which is `formed of folded sheet metal to provide a shelf supporting portion 16 and inwardly curved flanges 17, the edges of which are arranged in confronting relation and are adapted to interlock with the inner ends of the back panels 18 and 1S). The .inner ends of said back panels are formed with hook flanges 20, which slidably interlock with the curved flanges 17, as shown in Fig. 2, in section. The outer ends of' said back panels 18 and 19 are formed with similar hook flanges 21, which slidably interlock with the inwardly curved flanges 22 of the rear end corner supporting bars or members 23. The end corner bars or members 3 are also formed of folded sheet metal and are shaped to provide an inwardly projecting shelf supporting portion 24 and a lateral hook flange 25, the central portion of which is flattened to provide a longitudinal tongue 26, which is adapted to slidahlv fit in the vertically disposed end located groove 27 of the lend panel 28. The front portions of the end panels 2S are held in locked relation by the front corner bars or supporting members 29, which are also formed of folded sheet metal and are shaped to provide outer hook flanges 30, the central portions of which are flattened to form tongues S1, which are adapted to tit in the grooves 32 of the end panels, like the tongues :250 of the rear cori ner bars 23. The front corner supporting bars or members 29 are further formed with an inwardl inclined loc-kin flange 33, offset from e shelf supporting portions 34 thereof. and disposed in convergino' relation to the inclined flanges 35, whic extend from the tongues 31. The locking flanges R5 are formed, as well as the locking flan es 25 of the rear corner bars 23, with vertically spaced slots 3G, which are adapted to rbceive the locking arms or lugs 37 carried by thc end panels 2S. which are shown in Figs. 6 and 10 in perspective. The arms or lugs il? are formed with notches` 89 which re ceive the lower edge portions of the slots 36. as shown in plan in Fig. 7. The end panels 23 are pro-vided with' transverse cleats 40, which carry small arms 41, which are formed with openings 42. which are adapted to receive the lugs or pins of the end shelf supporting members 11.

Vertical wooden bars or members 43, which are formed with converging slots, are

interlocked with the

corner bar flanges

33 and 35. Bottom shelf sections tt are arranged hetween the central or intermediate supporting bars 7 and 15 and the end bars, the front edge portions of said bottom shelf sections being extended to lic in the same plane as the front faces of the front mem bers 5`and 43. Top shelf sections 45 are likewise arranged between said central or intermediate bars and the corner bars.

The front upper portions of` the lower shelf sections 44 are provided with sliding door tracks 4G, and the top shelf sections are provided with sliding door tracks 47. Slidin doors` 48 operate on said

tracks

46 and 47. A view of the track construction is shown in section in Fig. 14. Each track consists of .fr strip of sheet metal which is folded to provide U-shaped trackl portions 49 which arc held spaced apart by a central arched connecting portion 49. By this arrangement a single metal strip forms two independent door tracks and a single row of fasteners or screws extended through said central portion 49 will securely hold the two tracks. In place of wheels I employ runners 50, which are fixed to the doors. Each of these runners consists of a metal strip formed to provide a longitudinal channel 51 and lateral flanges Each runner is provided with a central arch 53 which provides a minimum contact surface for engagementwith the track on which it operates. 'Each runner is further formed .with a longitudinal slot 54 located in one end portion thereof and which interlocks with a screw 5l secured to the door. The

opposite end portion of the runner is pro' formed into springY coi-ls 5t) which termihate in biting prongs 57. which are adapted to be pressed into the side wall of the channel formed in the upper and lower edges of each door, thereby lmsing the runner securely in place. By pressing the coils 56 toward each other the biting prongs 57 may be disengaged fron'i the side walls of the door channels and the door easily removed. The manner in which the runners iontict with the door tracks is shown in section in Figs. 5 and 1l and in elevation in Fig. 5.

r`he shelf sections are formed with re- 58 located in the end portions tlieref of and which receive the (lished or concaved langest) of the locking members G0 which are held in position by a single screw 61. By forming the flanges Dit concave biting edges 59 are provided which are adapted to bite into the walls of the recesses 58. The locking members for the upper shelves are shown in Fig. 11 and in Fig. 4 and are of angular de ign, while the locking members for the intermediate shelf sections and the lower shelf sectionsV are shown in Fig. 12 and are not angular.A The shelf supporting members 11 are held in adjusted position by means of locking pins or oblong keys 62 which are provided with heads 62 having recesses G2 to receive the point of a screw driver or like instrument whereby pins can be readily lifted out of place. The pins fit snuglivv in the oblong openings 9 formed in the inwardly projecting sup ort-ing portions of the vertical front. an rear bars 7 and 15, and slidingly supporting Athe structure against relative movement.

In order to securely unite the adjacent edges of the shelf -sections arched bridge plates 623 are provided, these bridge plates ieing held in place by fastening devices which extend into the sockets formed by the horizontal shelf supporting sections. Two fornis of fastening ldevices are einployed, one form is illustrated in the central portion of Fig. 4 wherein a' screw bolt 64 extends through the socket of the horizontal `shelf supporting section 1] and is secured in place by a nut 65. The other forni is illustrated in the lower portion of the saine 'figure and comprises an upper and a lower screw bolt 66 which are held in clamping relation by Ameans of a connecting female screw 67.

In order tostrengthen the rear panels 1S) without increasing the amount of material usually required by corrugating. I form said panels with a series of parallel slots and off-v The wooden front. bars` or iucnibcrs 5 may be dispensed with and the front` supporting members 7 and lo forint-d with interlocked front. flanges tit) and 70. the interlocking being preferably etl'ectcd by curving the edge porti-ons of the: flanges to provide engaging hooks. as shown in section in Fig. Q4.

In Figs. 15. lt and 17 means for 'securely uniting the engaging edge portions of shelf sections and of adjusting tli'e elevation of the shelf sections are shown. In this. construction. a stationary inem-ber 71 is provided. this member being forinedli'fn'ovide three channels. The wall of the central channel 72 forms the means for securingr the member to a suitable support and is provroe'd with openings to receive screws or other fasteners. The central walls of the channels on either side of the channel are provided with vertically spaced openings 73.

the openings being arranged in horizontal 4alinenient` The central wall 72 is provided with an offset. eye 74 which is engaged by a tongue 75 carried by the adjustin member and tie 76. The adjusting member and tie 76 is provided with angular flanges 77' which are adapted-to be fitted snugly in grooves formed in the underside ofthe Shelf sections78, as shown in section in Fig. 16. The adjusting and tie member 76 is formed with longitudinally spaced eyes 79, which are offset to provide guides for the arms 80 of the latch 81. This latch is preferably formed ot wire and its central portion is contracted to' forni a handle 82. which is offset` from theel-ins 8O so as to'be readily grasped. Th latch 81 is provided with an angular portion 83 forming a stop which4 is adapted to engage a stop 84 carried by the adjusting nieinber or plate 76.l AThe cent-ral portion of said adjusting` member or plate 76 is formed with a channel and the central wall of said channel is provided with small recesses 85in which the inturncd a'rins oi' portions of the latch'81 are adapted to snap so as to hold said latch in its locking position. The terminals of the arms 8O are adapted to project through `tht openings 73 and the stationary member 71. The plate 7G is furtherformed with angular arms 87 which are formed to provide hooks 88 adapted to interlock with the lower edges of said openings 73 forinedin the-stationary members 71, as shown in Fig. 17. A joint plate 89 bridges the'upper edge portions of the shelf sections 78 and is-suitably secured thereto and is provided with a hook 90 on its iiner end which is adapted to interlock with the stationary member 71. The hooks 88 are .adapted to prevent the shelf sections 78 frn dropping and the'latch 81 is adapted to hold said hooks 88 in locked position. A. brace 91 is secured to one ofthe sections 78 and is formed with an angular upstanding arm having an offset hook 92 adapted to interlock with the stationary member 71, as shown in Figs. 16 and 17. The plate 76 is held in locked relation with the shelf sections by means of pivoted plates or latches 93 which are adapted to swing over said plate and prevent thedisplacement of the embedded flanges 77.

Fig. 18 shows a modifled form of the shelf supporting and adjusting means, in which yend supporting members 94 are pro vided, said members being of similar design to the members 71 with the exception that. the openings therein are shaped differently, the central wall of the central channel hav ing a series of offset. tapering sockets 95- which are adapted to receive the locking tongues 96 adjustable in the central channel 97 of t-he tie plate 98. The central wall of the channel 97 is provided with longitudinal slots 99 located near the ends thereof and the tongues 96 are provided with pins 100 which slidably extend through'said slots. The plate or member 98 'is provided with longitudinally spaced eyes 101 which form guides for thc side arms 10i! of the latches 103. The ends of the side arms 109 are bent to provide stops 102 which are adapted to Abe held in adjusted positions in the open ings 104. Thisarrangement permits of a relative movement between the en d supports and the shelves and avoids spilling of the contents of the shelves should the joints bcl tween the end supports and the shelves be come very wide.

In Figs. 21, Q2. and an adjustable bracket construction is shown comprising a stationary supporting member 105, which is formed with a series of vertically spaced openings 106 arranged in horizontal aline ment- The member 105 is secured in place by screws or fastening means extended through the central vportion thereof. The bracket consists of an angular bracket member 107 which has its upper horizontal leg braced to its lower vertical leg by a brace rod 108. The vertical leg of the bracket member 107 provided with rearwardly offset tongues 109 which are adapted to removably fit in the openings 106 and hold said bracket in various .positions upon the support 105. K

The stationary member 71 and the member 105fmay be formed Witha single vertical series of openings instead of a double vertical series, if such construction is found desirable.
