press the same downwardly against Y In Figure 6 is fied form of our invent-ion in which the lever spring 37, aswillbe readily apparent. An openingof the drawer 10-, disengaging member 40 from the lever 35, permits the upward return of the loclringbar under the action ofV the spring 37 and unlocks the remaining drawers 10, 4 i Y j y illustrated a slightly modiis of bell-crank form having its pivotal connection 36 `at the apex thereof-and its short arm 41 normally extended upwardly in the path of the drawer carried actuating member 40 to be moved inwardly by closing movement ofthe drawer 1.0 to depress the outer end of the other arm thereof and consequently the locking bar 30. y i l In operation it will be readily obvious that the drawers 10 are moved inwardly to fully vclosed position and, closing movement V'of the mast-er drawer 10 engages the actuatingl members 40 on the opposite sides thereof with the adjacent levers 35 depressing the locking. bars to .engage the tongues 25 inthe registered apertures 26 and 27 of the-adjacent guide members .12 and 18. The master drawer 10, isthen locked closed byits independentor master lock, not shown, andthe drawers 10 are consequently locked until the f master drawer is opened sutliciently to disengage the members 40 and the levers 35.

In` Figures 7 to 9, inclusive, another typesecured, as at 45, to a plate 46 to which the lever is pivoted. A pin or projection 47 is formed on the other free end of the lever 44 and normally lies in the path of the actuating member carried by the adjacent side of the master drawer 10.

In this form of our invention, the spring 37 has one end secured to the adjacent trunk panel. as at 39. andits other end secured to vVith this construction it will be readily evident that the til) locking bar 30 is normally yieldablyretained in inactive position and movement of the free end of the lever 44 to its dotted line position illustrated in Figure 7 byengagement of the member 40 with the pin 47 thereof depresses the outer end of the lever 44, carrying with it the bar 30 to engage the locking tongues 25 thereof in the registered apertures of the interloclred slide members. VWhen in locking,

The actuating member 40illustrated in Figures 7, 8 and 9, has its, outer'iend portion offset 'and parallel to the adjacent side of the drawer 'and isprovided Awit-ha vertical recess-51 the outerend 52 of whichis cut away sufficient tofpass under pin 47 vwhen the bar is in its upper-mostposition. As a result, closing movement of the drawer 10/e1igages the extended wall 53 of the recess 51' with the.V

pin 47, moving the bar to locking'position and engaging the pin. in the recess.l '"Ojpvening.,

movement of the drawer 10 insures the positive return of the locking bar,'tlie pin 47 being carried to. its dotted lineposition bythe 4end 52 of the actuating 'memberl i Y In Figures 7 and 8,'thefloclring harig() is illustrated as ysecured' to one side panel ofthe trunk, although it will be readily evidentfthat i two may beemployed if desired,` although one is 'suiiicientf l., y .i

The forward or outerend of the ledge 1'6 of each panel carried guide member is preferably provided with a guide extension Vor tongue 54-to provide means forA facilitating the: insertion of the ldrawers in the trunk.

The inner end of the drawers are positioned thereon and consequently the `flanges 19 i thereof are guided into the channels 14.

From `the foregoing description taken in vconnection with the accompanying drawings,

it will be readily apparent to those .skilled in the art to which an-invention of thisl character appertains that .wegprovide .an .improved` drawer guide and Vdrawer locking device which is concealed within the drawer section, whichis easily actuated bythe closing movement of the master drawer and which affords maximum vprotection against tampering with or therunauthorized opening of the trunk drawers. .l
