TQ all whom- 'ii may cof/266m:

lle it known hat l', Linconx M. Ssanxs, :i residen*v of Jnnleslown. in the (mint/i' of (.hrnianfizin :mil Siate of New York, have invented fx now .1mi useful improvement in Locking Iii-xiv@ for Shelving; ami I (l hereby lelclnre thev folioxi'ingr is l1@ z; full. clear, and @xavi clesfrriplion ihm-cof.

Ny invenlion reines to a locking device for shelves :imi more spe-Cial@ Ufshelws einpluyeii in runner-ii n wih umili-racks Where it is ,lesiiyl io adjust. the shelves at (lilik-rent lniffhts.

The obj@ 0f my invention is to nrc-ville :i inclcing iievico for shelves of this .character in which ille shelves. when once. adjusted in position :1re firmly and positively lui-lied so iuii. hersis no linhiliy of their being displaced or relais-Qd lg.' the inserion or ii'iihdramal of the bnnks. or other to be supported thereon.

To illes@ ends my invention comprises,

generally stated. u suit-able frame or casing,`

a removable shelf Supporiml. therein. with means for supporting the shelf at diez'ent heighs in said arising, and a reriicnlll'morable har haring inchinor (larioes adapted to engage the shelf and lock it securely in posiiion in one position of szlial bnr and in ih@ opposite position leaving the shelf free to he removed. f

Referring to theiirawings Figure 1 is a perspective view ai a portion of a case with my invention appiird thereto; 2 is :i View of fha shelf removed; Fig. 3 is :in eniargwl ffsnil of the locking device when in its locked position; and Fig. 4 is :i like view showing it in unlocked position; :inni Fig. is an enhirgcil derail in perspective of the imi-:ing device.

My invention is aiplicahle. lo'mamy clifferent forms and styles of @ses nn'shelues. and i do not wish to limit myself in :my way Lo the particular style of ruse or shelf in connection wih which my invention is illustmlud, :is thesis muy ha varied in nmny dillierent Ways according io vthe Ciiv'nm-v Speciaicn of Lfers 2me-nt.

Seemed to lhe casing :iz'e'the hollow nmmbers or channels l5, said channels being pzjoi'idefl uiong i apertures sain :iperiurrs being arranged :ii sull'niflee i ferrals apart il give the 'desired mijnslmen to lie: shelves. Ther-e. :1 'iloycfl the @nier innge serves (.znni L, :is e. str un; nar for a loot VWhere doors are employed. The shelf i is provided with the extensions li' which are :ulnnled to enllr the apertures 16 in the clmnn s l5 and said extensions are provided Willi ihe notches 1S. These. npez'lurcs li forni the supports at di'iierent heights in support the .'sheives. iTihin the channel 15 is the iocking'b'ar 19 .1 r .1. L. Y Much nia)- ne 1n channel wrm ann said lockzng-bar is movable vertically within the hollow member or channel 15. This is accom- .plis'ned hy means of the Studs 20 on s:\id

lacking member, said stili-.ls having, if desil-ed, the knobs 21. These studs engage the sic-.ts in iin` charnel 35. Tlwse slots 22 have the recess .23 o hohl the locking bnr in iis released'frr raised position, :is indicated in Fig. The inner lzingafof the lockinglmr is forineii with notches 24. which provide the lonking tongues or lugs 25 adapted if) @gags hv notches lizin the extensions 17 of the shehes when the. locking-har yis lowered, :is indicaieal in Figs. 3 and 5.

ivhe'n the shelf is in irosiiion in he (fase sind locked therein. the leaking-bnr will be low@ v withjis locking 'tongns engaging the notches in the extensions ci the shelves. llireby holding the shelf against'. lis-placa more( h v the withdrawal oi' ih@ hunk.

AThe shelf may then he Withdrawn fronrthe openings in the ohzinnels 14 and raised or lowered the deiired extent, whenthe extensions are invfried in 'the proper openings in the chans 14 and the front extensions 1i' are moved into the proper apertures 16 ot the ini-ller.' bars l5 whereupon the locking bars are again lowered and the locking tongues thereon engage the notches of the extensions Y to secure the shelf in position.

lhnt. I claim is:

l. The combination of a snit; 'sie rinse. a removable shelf supported therein iwi-iii;

one element of a positive interlmking connotation7 supports at, different heights on mid, case, and n vertically adjustable looking hat' having the other elementof an interlocking connection engaging the first named element to hold said shelf in looked position.

2. The combination of a suitable ease, a removable Shelf supported -therein having one element of a positive interlocking conneetiont supports at ditierent, heights on said vasee and u vertically adjustable locking har having lugs attached to engage Suid element of a nositiw interlocking connqrgtgg t@ hold the. shell in looked position.

3. The Combination of n suitable oase. :i hollow support, having seats formed therein.l a Shelf having :i projecting portion .adapted to enga e said seats. and a looking bar within t ie hollow shelf supportadapted to engage. the projection on said Shelf and loclc it. in position.

4. The combination of a suitable ease, a shelf Support having seats ,formed therein, a shelf having a projection adapted to engge said Seats, Said projection having a notch therein und a looking har having nn over-hanging lug adapted to engage said notch.

5. The combination of a suitable ease, a channel member Seemed thereto having seats formed in one o its flanges. a lock-l ing ber movable within said channel member, and :i snelf having a projection adapted to ent-er the openings in `nid ilange, Said looking har adanted to engage Suid projection tolock saint shelf.

'6. The combination of a enitahle cane, a channel nieniher snjported thereby lntving 'seats formed in one of its tinnjres, n shelf having a projection adapted to engage said seats, and a vertieallv movable looking bnr in said channel meniher adapted to engage said project ion to loci: said shelf.

'i'. The combination of o. .suitable cane. a channel nien'iber carried there v having .it formed in one oi its tinnges7 n shelf haring a projection adapted to engage siii seais, und a vertically movable looking niemher Within said channel member having engaging lugel lo engage said jnojeclion on said Shelf.

v8. The combination of n suitable case, a

clinnnel member carried thereby having,

seats formed in one of its flanges, a shelf having a projection adapted to engage -Said sente2 :ind a vertically moving channel har within said channel member, said channel har having engaging ings formed on one of its langes adapted to engage the projection on che In testimony whereof, l the Said Lincoln; M. S'rn-ARXS have hereunto set in v hand.
