p Application filed October 22, 1920. Serial No. 418,795.
the locking of the drawers or withdrawable yboxes of a druggists cabinet of thegeneral type shown in my prior Patent No. 946,467, granted January 11, 1910.:
The accompanying drawing illustrates my invention: In such drawing7 Figure 1 is a perspective rear view of a druggists cabinet embodying my improved lock, with some -of the drawers partially pulled out; Fig. 2 is a fragmentary horizontal section through a 4portion of. such. cabinet, including the drawer which effects the locking of the remaining drawers; Fig. 3 is a perspective view of a fragment of one of theV slidable Y locking barsgFig. 4 is a vplan of a fragment of one of the lockingbars mounted in place inits floor board and showing the associated pivotV pin of a withdrawable drawer; Fig.
V5 is a fragmentary sectionY on the line 55 of Fig. 2; and, Fig. 6 is a'front elevation of the cabinet on a smallerscale. v Y
The cabinet consists of a usual .casing having side walls 10` and` a plurality of transverse horizontal shelves 11, which include `those at the top and bottom'and provide v space for aplurality'of tiersof withdrawable drawers 12, the cabinetshown having four tiers of five drawers each, and each tier of drawers having ashelf above it as well as below it so that there are live such shelves.
The drawers 12 are provided near one rear corner with upwardly and downwardly projecting pins 13,v which extend into slots 14in `the lower and upper surfaces Vof VJche f adjacent shelves` 11. shelves project forward beyond the drawers `whenthe latter are shoved back, and kthe lslots -14 vextend forward beyond the'front ends of the shoved-back drawers; so that v when the drawers are pulled forward the pinslfare guidedby 4'the slots 14, which limit the forward movement of the drawers -14, to give access to the drawer from the side The and permit a drawer Avto be swung about its pins 13 as a pivot when such pins have been drawn to the front end of the' associated slots and permit it `to be closed on the other side as well as on the front and back and bottom 'and top.V
,each shelf 12 is providedwith a'ltransverse Aslot in'which is mounted a slidable bar 15, vwhichat one end isconnected-by` a link 16 to an arm V17 fiXed'on a vertical rodlSSsuitably mounted for turning in arecess on the "inner face of one of the sidewalls 10; 'The rod 1.8 isv turned in opposite directions iby pulling out and pushing i'n'one'of the 'draw-A "Near its rear edge, vthe upper surface of ers which lies against such side wall,1saythe I right hand drawe'r12v of thefsecond tier from thetop asfvie'wed from.v the front. For this operation, the lrod 18'Lhas Vtwo larms 19 and 20 which coperate with the rear wall 21 of the drawer12, sothat when such drawer is pulled vforward the rear wall 2l strikes the arm 19 and turns the-rod18'i-n one direction and when such drawer is pushed back the rear -wallfstrikes the arm 20 and turns the rod 18 in they "other: direc#` tion. These oppositelturning movements of 'the rod18 slide the bars 15 in 7opposite directions, all such bars operating correspondin`gly.` The bars 15 'arerthicker (vertically) than the depthof the slots'14,and are prov nv ide'd with'notches 22 the bottoms of which are in the. saine horizontalfplanes as the bot-V toms of l.the slots 14.l @By the" slidingfof the bars 15 Y.the'notches 22 are brought 'either cintok line 5 with the kslotsf14,'to unlock theV drawers, as shownin Fig. 1,'or 'are'moved out f the line of such slots, to lock the draw- V ers by closing `the slots 14" in front ofthe pivot pins 13 of the shovedback drawers. as shown, in'v full lines inFig.Y 4. Eachl lnotch directions from apoint near the front-.edge
12,2 Vexcept that for the drawer '12'v has oney sfide wall 23 horizontally inclined in both u A A Vof thebar 1.5, so that when such bar is shoved to theY right (Figs. 1and,4)"to lclosejthe associated slots 14l such inclinedfwalls 23 will engage the pivot pins 13 of any 'drawers'- which are notV shoved fullyfback and by.
their'camfaction onsuch pins will either` shove the drawers completely back andlock l'themV place-or will 'shove them farther 'forward to c all attention to the` fact that they are not locked, will be' clear'frem the dotted and full-line positions in Fig. 4L.
In order that this cam action may produce movement of the pins 13 along the slots 14,Y
and not along theline of movement of the bars 15, staples 211 are driven into the shelves V11 over the bars 15 at the right-hand sidev (Figs. land) of each slot 15; these staples prevent the Vpins 13 Vfrom being carried transversely of the slots 141 by-theaction of the sliding bars 15.
A notch 22 is provided in the bars 15 for Y n each downwardly extending pin 13 of each drawer; andas stated, all theseV notches V22 are similar and are provided with thev incli-ned wall 23 with the. exception of the notch 22 `for the pin on the drawer 12. This notch 22 is made of suiiicient width,
lengthwise of the bar 15, so that its Ywalls never cross the associated slot 11i and so that thatparticular'slot 14 is neverclosed. This vpermits the drawer 12 yto cause turning. of the rod 18 to locky andv unlock the remaining drawers as the drawer'12 is shoved inor pulled out,V and avoids interference withk such-shoving in and pulling` out an account vof any interlocking vof-the bar 15 with thev pivot pin 13y of that drawer. The drawer 12 is provided with` asuitable lock 25, usuallya key lock, by which such drawer may be locked in closedV position; and this locks all the drawers `of the cabinet.
