RroRATIoN or WISCONSIN DRAWER-LOOKING DEVICE Application filed March 19, 1926. Serial No. 95,986.

In the wardiobe trunk art, it is highly desirable that means be provided for readily locking the drawers in closed position and one type of drawer lock commonly used consists of means concealed in the section and having a master lock to secure the remaining drawers closed. It is also essential that the locking means not only be reliable in operation and of strong construction, but that it be suciently lightrin construction to prevent an undue increase in the total weight of the trunk and be capable of production at a lowcost.

It is, therefore, an object of this invention to provide an improved drawer locking device which will very effectively lock the drawers and which, by virtue of its construction, will not unduly increase the weight of the trunk, but, at the same time, will be strong and durable to withstand the rough usage to which a device of this character is subjected.

A further object of this invention resides in the provision of a durable and efficient drawer locking device especially adapted for use with wardrobe trunks which is extremely simple in construction to facilitate its ready manufacture and application to wardrobe trunks at a very low cost.

And a still further object of this invention resides in the provision of an improved locking bar actuating member carried by the master drawer and keeper foi cooperatingI with the locking bar which is so constructed and designed as to materially strengthen the drawers at the connection between the side and rear walls, y

Vith the above and other objects in view which will appear as the 4description pronovel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment-of the lieieindisclosed invention may be made as come within the scopeof the claims.

In the accompanying drawing, I haveillus` trated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure l is a perspective, sectional view igure 2 is an enlarged, fragmentary, sectional view taken through Figure l on the plane of the line 2-2, the top or master drawer being in its position prior to engagement with the locking rod or bar tolock the remaining drawers;

Figure view and Figure tail view,

3 is a fragmentary, perspective illustrating one of the lower drawers,

4 is an enlarged, fragmentary, de-

with parts broken away, illustrating the improved spring housing and mounting member for the eferring now more lower end of the rod.

particularly to the accompanying drawing, in which like numerals designate like several views, drawer section parts throughout the the numeral 5 designates the of a wardrobe trunk or the like including side and rear walls 6 and 7, respectively, the side walls having series of drawer supports or slides 8 fixed thereto to slidably mount a series of drawers 9. The

drawers are of substantially box shape having a bott om l0 and front, rear and side walls ll, l2 and 13, respectively.

The up may be te controlled lock 14 fixed to its front wall Y cent the bolt adap carried b ated by t permost drawer is preferably what rmed a master drawer having a key adjaupper edge and having a locking te'd to be engaged with a keeper l5 y the top wall 16 drawer closed. adapted to be operhe master drawer, are mounted in the drawer section and lock the remaining drawers in yclosed position when the master drawer 1s fully closed. The locking means for the remaining drawers consists of a dc-' vice preferably secured to each side wall G adjacent its inner edge and having means whereby closing the master drawer actuates the locking drawers.

device to engage the remaining If desired for the purpose of of the drawer y economy in the lower priced trunks, but a single locking device may be employed, although in the higher grade trunks two are employed to provide a more rigid lock for the drawers. As each locking device is iden` tical, but one has been shown and but one will be described.

A locking bar or rod 16, preferably formed from a single length of rod metal having a plurality of locking .tongues 17 formed therein at intervals equal to the heights of the re'- spective drawers, is rotatably secured to the section side wall by means of one or more attaching members 1S having a bearing portion 19 for rotatably receiving the rod 16 and a combined spring housing and mounting member 2O having a portion 21 in which the red 16 is received together with a spring 22', to be later described.` The locking tongues 17 are formed by bending orstriking the rod 16 outwardly, as clearly illustrated in the drawing, and form cranks pivoting from the axis ofthe vertical portions of the rod and adapted to normally rest against the side walls 6 out of the pathof locking lugs 23 carried by the adjacent side walls of the drawers at their inner ends. The master' drawer has an actuating member 33, to be later described, arranged to rotate the rod 16 and moves 'the locking tongues 17 into the paths of the locking lugs 23 and thus restrain the opening of the drawer as long as rod 16 is held against rotation by the master drawer'.

The locking lugs 23 are eachvpreferably formed from bendable metal having one end portion 24 secured to the rear wall 12 of the drawer to which it is secured, as at 25, and its other end beingl bent about the drawer 'side wall and there secured, by a flange 26, that portion of the member 23 along theside wall being inclined outwardly and forwardly, as at 27, from the rear drawer corner to provide an abrupt angular porti-on 28 forming an abutment which cooperates with the adjacent locking tongues 17. 1t will be apparent that the locking lug construction,illustrated provides a brace for connecting the side and rear walls of the drawer thus considerably strengthening the construction and when the drawers are closed and the rod 16 rotated to position the locking tongues 17 V angularly from the section side wall, the locking tongues 17 extend transversely between the section side wall an'd the drawer into the path of the abutments or shoulder portions 28 of the drawer locking lugs and thus lock the drawer closed until the rod l16, is left free to rotate. In this position of the tongues 17 they bear against the flanges 26 with a slight camming action whereby' the tongues serve not only to lock the drawers but serve as rigid transverse braces extending between the section side walls and the inner ends of the side walls of the drawers to maintain a definite spaced relation between the side walls `of the section and the drawers under all conditions of handling in transportation. These tongues 17 are substantially arched for greater rigidity in their locking and bracing position, vide a flat bearing contact against the adJacent flange 26 on the drawer catch.

A spring 22 normally urges the rod 16 to a position with the locking tongues 17 against the drawer section side wall to permit the unrestricted opening and closing of the drawers. Spring 22 is coiled about the lower end portion of the rod and has one end directed inwardly into a slot 29 formed in the rod 16 and its otherv end directed outwardly, as at 30, and engaged in a` slot 31 formed in the portion 21 of the mounting' member 20, the spring 20 being normally under tension to tend to rota-te the rod 16,- as previously described. n

The rod 16 is rotated against its spring to wind the same thereon by' cooperatingl means on the upper end portion of the rod and on the inner end portion of the master drawer. The upper end of the rod 16 is directed laterally to form a crank portion 32 to normally eXtend into the path of the actuating member 33 mounted on the master' draweri The member 33 is substantially identical in construction with the locking lugs', except that the inclined portion 27 thereof is at an increased angle and of the drawer to function as a cam for engaging the crank portion 32 of the rod. Clos'- ing of themaster drawer causes the cam por-v tion 27 to engage the `crank arm ofthe rod moving it and the locking tongues 17 to the dotted line positions illustrated in Figure 2,

the locking tongues 17 extending alngularlyv from the wall ofthe drawer section and into the path of the locking lug shoulders 28v of the drawers in closed position. After the master drawer has been moved to full closed position and its lock 14 engaged with the keeper 15,l the drawers are locked and to gain access to the drawers it is necessary to first unlock the master drawer and open the same sufliciently to permit the crank portion 32 ,of the locking bar to move to its' position illustrated in Figure l2, the spring 22 tending to move the master drawer to open position immediately upon release of the lock 14. Y

From the foregoing description takenin connection with the accompanying drawing it will be readily obvious to those skilled in the art to which an invention of thischarac-v ter appertains that I have provided a very simplined and improved type of drawerl locking device which will provide anleffec'tive lock for the drawers and which will `by reason of its extremely simplified construction be very economically manufactured.
