Application filed September 29, 1927. Serial No. 222,887.

The object of this invention is to provide a lock for the drawers of a wardrobe trunk which will give eliective operation and at ing and'unloclring of the trunk, and the removal of the drawers. While I have disclosed my invention as applied to a trunk, it should be understood that the same may be applied to other structures, and I dov not therefore 'ish to be limited to its application to a trunk. Further objects will appear in the description to follow:

In the drawings, Figure 1, represents a perspective view of a trunk showing my invention applied thereto. igure 2 is a top view of my improved locking device, showing the same in both locked and open posi tion, and Figure 3 is a front view thereof. Figure l is a front view of my locking bolt, and Figure l is a section thereof. Figure 5 is a detail of the spring used in my lock- 'ng bolt, and. Figure 6 shows the spring retaining member, in front and end views. Figure 7 is a front and side view of the extension adapted to be fixed to the locking bar of the trunk, for carrying the locking bolt. Figure 8 is an enlarged cross section of the assembly of my locking bolt, fixed in the extension member.

Figure 1 illustrates a usual type of trunk havi a series of drawers or other compartments, and supplied with a locking bar, 1 which is adapted when locked in position to prevent the opening of the drawers. In order to hold this bar in position, it is provided with an extension 2 illustrated in detail in Figure 7. The locking bar is hinged at 1 and is adapted when in open position to be maintained in the open position of Figure 2. I have mounted on one of the drawers, a latch assembly 3 having a latch bolt 3 of the conventional type in which the bolt, is spring pressed in an outward direction, and which is controlled by the usual cylinder lock 5, shown in Figure 3 in a manner well known in the art. The eX- tension 2 of the locking bar 1 carries a locking bolt 4: shown in detail in Figures 4 and 4 This locking bolt is pressed in an outwardly direction by the spring 5, for reasons which will be hereafter explained.

In assembling the locking bolt 4;, the spring is first inserted within the hollow cylindrical portion 6 of said bolt and the spring retainer 7 is then inserted to the opening 8 and the extensions 9 are allowed to rest in the slotted ends 10 of the locking bolt. Vhen the spring retainer lies at right angles to the longitudinal axis of bolt 4 its extensions 9 are of such length as to extend outside the slots 10 for a purpose hereafter explained.

Thev locking bolt is then pushed through the hole 11 of the extension member 2. While this is done, the retainer 7 is allowed to assume an angular relation relative to the bolt 4-, and the slots 10 so that it may slide through the hole 11' with the bolt 4. The retainer 7 is then placed, so that its ex tensions 9 protruding through the slots 10 iit within the slots 12 of the extension plate 2. The sides 13 ot' the slots 12 are then hammered or staked over the extensions 9 and are adapted to hold the same in'position so as to confine the spring within the cylindri'cal portion 6 of the locking bolt 4. This locking bolt 4 is provided with a cylindrical hole 14 in which the latch bolt 3 fits, to loci; the bar 1 in position. It will be observed in Figure 2 that the bolt when'in locked position must be pushed against the spring pressure 5, so as to bring the hole 14 within the scope of movement of the latch bolt 3%, so that there may be an interlocking of the, two. This movement will be of such amplitude as to bring the bolt head 15 flush against the plate 2 as illustrated in F igure 2.

The purpose of this arrangement is such as to economize necessary space and permit opening of the drawers when the'locking bar in the open position, illustrated in Figure 2. In that position, the locking bolt 4: will be withdrawn (due to the action of spring 5) entirely from the plane of movement of the drawer containing the latch 3 and also the other drawers ot' the trunk, and'the same will be permitted to open. If this were not the arrangement used, the bolt 4 would project from the locking bar land it would be necessary to have a double hinge in order to remove the locking bolt from obstructing position. Similarly, by having a spring bolt, it will be observed from the locked position of Figure 2 that once the bolt l is pressed inwardly into cooperation with the latch 3 that the same fits very closely to the drawer and allows for a full closing movement of the trunk. Thus, by a simple spring bolt arrangement of the look, so as to pro vide for both a spring locking bar and a spring latch to cooperate therewith, I have obtained a. trunk lock in which the greatest economy of space and arrangement is obtained. then the trunk is open the bolt 4 will be removed from obstructing the free movement of the drawers, while when it is desired to lock the trunk, the inwardmovement of the'bolt 4 will lock the bar 1 in position and at the. same time the bolt will be removed -from interference with the/locking of the trunk.

- I claim:

'1. A trunk comprising a series of drawers, a locking bar provided to prevent opening of said drawers, a latch bolt mounted on one of said drawers, a bolt mounted on the lock.- ing bar and spring pressed relatively thereto and having means adapted to cooperate with the latch bolt, said spring pressed bolt being adapted to be pushed against the pressure of the spring into cooperation with thelatch bolt to lock the locking bar in position.

2. In a trunk, a locking bar hinged to the trunk at one edge and having a lateralextension fixed thereto at a point on its opposite edge, a locking bolt mounted in said extension and spring pressed outwardly away from the trunk body, a spring latch bolt mounted on a part o1 the trunk and adapted to enter a portion of the locking bolt when the same is pushed against its spring pressure so as to lock the locking bar in looking position.

3. A trunk lock comprising a locking bar adapted to prevent opening of a series of drawers, a latch bolt on one of said drawers, a locking bolt on said locking bar and havlng a-slot therein, a sprmg mounted 1n sa1d lookadapted to lie against said latch in a plane parallel to the bolt thereof, a locking bolt mounted in said bar adapted tor movement perpendicularly thereto and the latch bolt and adapted to interlock with said latch bolt and a spring normally urging said locking bolt from interlocking position.

5. In a trunk, a locking bar, means for maintaining said bar in locked position comprisin a latch having a spring bolt, alockinc; bolt carried by said bar, and'having means adapted to interlock with the. latch spring bolt, a spring mounted to normally press said locking bolt relatively to said bar and away from looking position. said looking bolt being adapted to be pushed against the resistance of said spring into locking relationship with said latch bolt.

6. In a trunk, a locking bar hinged to the trunk and adapted to swing from and into locking position, a spring locking bolt mounted in said bar and adapted to be spring pressed outwardly when in unlocking position so that the inner end thereof will be flush with one side of said bar, said looking bolt being adapted to be pushed against its spring pressure into locking position so as to bring its outer end flush with the other side of said bar.
