TRUNK LOCK.

Application filed July 7, 1923. Serial no. 650,188.

This inventionrelates to wardrobe trunks and particularly to drawer locking means for trunks of this character.

Wardrobe trunks now in extensive commercial use are ordinarily provided with a plurality of drawers and are furthermore provided with looking bars designed to lock in closed position all of the drawers. This invention relates particularly to the lock carried by this locking bar.

This invention has for its object to simplify and improve locking device of this character, and to this end this invention consists in the novelcombination, construction and arrangement of parts all as will be made more apparent hereinafter as the description proceeds, especially whenconsi'dered in connection with the accompanying drawings wherein of the locking bar showing the look; I

Fig. 3 is a detailedview, showing the interior construction ofthe lock;

Fig. i is a similar view with the bars in unlocked position;

Fig. 5 is a central longitudinal sectional view on the plane indicated by the line 5-5 in Fig. 3;

' Fig. 6 is a transverse sectional view; and,

Fig. 7 is a detailed view of the locking discs. 1

Referring now particularly to the drawings wherein like reference characters indicatelike parts, it will be noted that a portion of a wardrobe trunk 10 is illustrated, having mounted therein a plurality of drawers 11. These drawers are secured in closed position by means of a locking bar 12, hooked at its lower end into a slotted plate 13, secured to the trunkand engaging intermediateits length an open end-ed slot, formed in a plate 14, also secured to the trunk. The bar is preferably hinged as at 15 intermediate its length. 7

The bar 12 has secured at its upper end a lock enclosed in acasinglG, there being contained in. this casing a pair of locking levers 17, pivoted as at 18 and normally urged outwardly to the position illustrated in Fig. 3, by means of an U-shaped spring 19. In this position the angularly extending locking projections 20 of the levers 17 V engage keepers 21, forming a part of the escutcheon plate of the trunk to securely lock the bar 12 thereto.

A cam member 22, forming a part of the locking mechanism is rotatably supported within the casing 16 between the lower ends of the locking levers 17 andwhe'n rotated tends to. move these levers to unlocking positlon, asillustrated in Fig. 4. This cam member 22 is rotated by a key 23, adapted to be inserted in a rotatablekey-receiving member 24. This rotatable-'key receiving member extends through a plurality of looking or ward discs 25, non-rotatably supportedv withinthe casing upon pins 26. These discs are provided centrally thereof with openings 27, communicating with slots 28.

' The openings 27 are of different diameters, and the key 23 insertable therethrough must thereforebeformed with suitable di1nen-.

sioned slots to permit its rotation with reference to the discs 25. The key-receiving member 24 engages the cam 22 in such a manner as to rotate the same when the key i'nsertable in the member 24 is rotated. Obviously, therefore, when the proper key .is inserted in the key-receiving member24 the key and the. member 24 may be rotated relatively to the discs 25 and'in consequence thereof the cam 22'will be rotated from the position illustrated in Fig. 3 to t-hat illustrated in F ig. 4, whereupon the locking levers 17 will'be moved to unloekedposition against the tension of the spring 19. It will be also immediatelyapparent that various combinationsmay be provided by altering the arrangement of the discs 25, thus necessitating keys of different formations.

While one embodiment of thein' -iention has been described herein in some detail, it is not intended that the inventionbe unnecessarily limited, but reservation is made to make such changes as may come within the purview of the accompanying claim."

Havin thus describedthe invention What is olaime is:

' A look comprising a casing, a pair of looking levers pivotally mounted therein, a rotat-' able cam for moving said locking levers to unlocked position, a plurality of looking discs non-rotatably mounted 'ivithin said casing and provided with apertures of difierent diameters and a key-receiving member passing through said locking discs and engaging 10 said cam, said key-receiving member being rotatable upon the insertion of a proper key to rotate said cam.

In testimony whereof, I aflix my signature.
