WARDROBE-TBUNK DBAWER-LO CKING- DEVICE.

Application filed september 20,1916.

To all "whom it may concern Be it known thatl, ARTHUR P. J A1\IES,' & citizen ofthe United States, residingin the city of Richmond and county of Henrico and State of-Virginia, have invented a new and Improved lVardrobe- Trunk Drawer- Locking Device, of which the following is a specification.

This invention, which has general reference to drawer locking means, is nroreparticularly directed to the production ot'a new and improved locking meansor device par ticularly' adapted for use in connection with wardrobe trunk-drawers and other like arrai'ig'ements of nests of drawers, and which embodies a'siinple, inexpensive and effective arrangement of parts adapted for being readily applied to the conventional formsof wardrobe trunks now in use without any material change in their structure. 1

riimong'other objects, my invention seeks to provide asimple and automatically operatedlocking device for wardrobedrawers and the like, in which the locking elements are especially designedrfor taking careof the sidewise and arring movements Ofth'e' drawers caused by rough handling while the trunk is in transit andhin' such manner that the said" locking elements are relieved. of strain and held from being .read'ilyclogged or otherwise shifted outofthe proper opera tive condition.

Another and essential feature ot my in vention lies in an improved construction of locking; device, of .the 1 general character stated, in which is included simple and posi-' tively operating means i for permitting any" and all of the drawers,- other than the operating drawer, to be pushed in: and locked after-the operating drawer has been: previ ouslypushed in' and key locked.

With the above and othergobjects iin=view, my invention consists a locking :device or means of the character statedthat embodies the peculiar features ofconstruction and novel arrangementof the parts hereinafter" eix plained specifically outlined in the appended: claims and illustrated inthe accompanying drawings, in which:

ating or key locked drawer and some of the other drawers being at then pushed in or locked position and the remaining drawers at their partly opened or pulled out position.

Fi 2 is a horizontal section taken through the upper key lock drawer, the drawer being at its forward or unlocked position.

Fig. 3 is a similar view that shows the key locked drawer closed and at its locked position.

Fig, 4 isa horizontal'section of one of the lower drawers and indicates the drawer as being pushed inwardly and engaging the automatically operating locking latch 'm'enn ber that cooperates therewith. I

Fig. 5 is a perspective view of my improved trunk drawers locking means, a portion of the trunk casing being shown to illustrate the-manner in which any said locking device or means is applied.

Fig. 6 is a detail perspective view of a modified form of springdevice' for turning the=rockshaft or red of the locking'devicein positioirfor being engaged by the master or operating drawer hereinafter more speciii cally referred to. r

Fig. 7 is a detail horizontal sectionthat illustrates the position of one of the locking latches, with respect to the slot in the adjacent drawer, after the upper or operating drawer has been closed and locked and the latch' carrying rod rocked to the initial looking position.

F 1g. 8 is a vertical section of one oi the lower drawers and illustrates the projecting housing device for the latch heads, hereinafter referred to. i

In wardrobe trunks now on the market, so far as Iknow, the drawers in the bureau side usually have separate locking: means and, by reason thereof, frequently in the handling of the said types of trunks,- the individual locks readilybecoine more 'or strained and rendered inoperative while the wardrobe is in transit.-

Again; in the use of wardrobe trunks ha ing individual key lockedrle vices, when the trunk drawers are hastily pushed back to permit of closing the two'sections fthe wardr0be,the locking of one or niore of the drawers isot'ten overlooked and hence 'dur ing travel the unlocked drawers are more or less jolted, often injured and the contents of the drawers more or less disturbed. V

In carrying out my invention, the bureau part of the trunk casing is provided on the inner side of the back 1 with a series of horizontally disposed brackets or bearings 9 in vertical alinement.

3 designates a rock shaft in the nature of a stout steel rod, and the said shaft, at suit able intervals, is provided with horizontally disposed forwardly projecting crank members 3O that'terminate in latch heads 31.

One of the latch members 30 is provided foreach of the drawers l, excepting the key locked drawer, and each of the d 'awcrs at adjacent their respective latch crank members 30, is provided with a horizontally elongated slot for the reception of the latch heads 31, that edge of the slot 40 engaging the head 31 being metal sheathed to avoid wear and provide for a close fit of the parts when the drawers are at their in or locked position.

35-35 designate cup shaped sheet metal housings, and each includes a base flange 36 for conveniently securing the same to the drawer bottom, adjacent the latch slot 40, as shown.

The housings 35 are provided for preventing the articles packed in the drawers from engaging or interfering with the latch heads 31 of their respective locking members 30.

All of the drawers, excepting the top or operating drawer, are of such width that when pushed inwardly to their limit, their front edges will be flushed with the front edge of the bureau casing and the top drawer is of sutliciently less width to allow for a supplemental back movement thereof for effecting the operation of adjusting the locking devices to their drawer locking position, but the said top drawer, when not at its key locked or operative position, has its front flushed with the front edge of the bureau casing, it being forced forwardly to such position by a leaf spring 7 that isat tached to the back wall of the casing and which engages the rear end of the drawer, as is clearly shown in Fig. 2.

While I have shown the top or operating drawer as of less width than the casing and the other drawers, the said top drawer may be of the same width as the casing and the other drawers contained therein, it being understood, that when of practically the same width as the trunk casing, the front end of the-said top or operating drawer will be extended beyond the front of the casing to allow the unlocking device to'work.

8 designates a stout leaf spring arm fixedly;

attached to the upper end of the crank rod 3 and the said arm 8, forms as it were, a crank member that projects from the rod in a direction substantially at right angles to the crank latches 30 and the said member 8 is normally forced outwardly in the direction of the arrow a on Figs. 2, 3 and l, by another leaf spring 9 that is also attached to the upper end of the crank rod 3 and has its free end 90 held to bear against the back of the bureau casing, as shown.

Instead of using the leaf spring 9, the spring tension device for normally forcing the crank like spring member outwardly in the direction of. the arrow a (see, FigsQ, 3 and l), may he in the nature of a wire spring 91 coiled about the rock shaft or rod 3, and held with one of its ends attached to the rod 3 and the other end to bear against the back wall of the casing, as clearly shown in Fig. 6 of the drawings.

The straight spring member 8, as will be readily seen from the drawings, is heavier than the spring 9 and hence by pushing the operating drawer, usually the upper one as shown, into therecessed position as shown in Fig. 3, a block 10 attached to the back of the said upper drawer contacts with the spring arm and thereby causes the shaft 3 to turn in an opposite direction to which it is f normally turned by the spring 9 and thereby brings the-locking latches to the position best shown in Fig. 4, by reference to which it will be readily understood that when the locking latch 30 is thus positioned, the beveled head 31 thereof is then in position for icing engaged by that edge of the slot in a lower drawer with which it interlocks site direction from that caused by pressure exerted on the resilient crank member 8 by the closed master drawer, and, thereby permlts the lockingrlatch head 31, when its beveled edge is engaged bythe lower drawer,

to spring back under pressure and thus al- 7 low any and all of the drawers, belew the top or operatlng drawer, to bepushed back and locked, even though the top or operating drawer has been previously locked by a suitable key actuated device.

Another advantageous feature in my in vent-ion is, that the spring membersS and 9 take care of the jarring and sidewise move ments of the drawers incident in the rough handling of my wardrobe trunk when in transit. d V -i From tbe'foregoing description taken in connection with the drawing, the complete construction, the manner "of operation and the'advantages of my invention will be read the artto master or operative drawer and a subsidiary I drawer; of arotary locking device mounted on the trunk casing, the said lock ng device including a flexible member projected into the path of the said master drawer for rotating the said locking device to the locking position, said locking device also including members adaptedto be engaged by the subsidiary drawers to flex said fiexiblemeinber when said subsidiary drawers are closed after the master drawer is closed, the said locking device also including a spring element for rotating it to the unlockmg posi-" tion when the master drawer is open.
