LOCKING DEVICE ron nnawnns.

To all whom it may concern .Be it known that I, JOHN'S. KRAMER, a subject of Austria-Hungary, residing at Steger, in the county of Will and State of Illinois, have invented new and useful Improvements in Looking Devices for Drawers, of which the following is a specification.

This invention relates to bureaus, dressers and other similar articles of furniture, and its object is to provide a novel and improved arrangement of drawers and means for locking the saine. I

The objects stated "are attained by means of a combination andarrangement of parts to be hereinafter described and claimed, and

- in order that thesame may be better understood, reference is had to the accompanying drawings, forming a part of this specification. 7 I

In the drawings, Figure 1 is. a perspective view of th bureau; U

Fig. 2-is a central cross-section thereof; Fig. 8- is a cross-section taken adjacent to one end of the bureau, with certain drawers omitted;

Fig. 4 is a perspective view of a drawer lock; o p

' Fig. 5is a plan view of one of thedrawers; Fig. 6 is a perspective View, partly broken away, of 'a drawer or slide associated with the drawer shown in Fig. 5;

Fig.7 is a perspective view, partly broken away, of the drawer shown in Fig. 5, with the slide of Fig. 6- omitted;

Fig. 8 is adetail in perspective of certain parts of the drawer lock;

Fig. 9 is a detail in'perspective showing another drawer lock, and I Fig. 10 is a perspective view of a drawer controlling said lock.

Referring specifically to the drawings, the frame of the structure comprises a back 1,

end walls 2, a top 3 and corner posts 4 which extend for a short distance below the bottom of the structure to serve as supporting legs.

The design of the structure is such that it has.

the general appearance of a bureau or dresser. I g I On the top 3, at the ends thereof, are drawers 5 .and 5 which are housed in casings 6 and 6 and the't'op in the space between these casings serves as the instrument board of a talking-machine shown diagrammatically in Fig.2. A lid or coverclosing down on the top 3 and over the tone arm 7 and turntable Specification of Letters Patent. 7

horn 10 of. the machine extends from the top i 3 down into a compartment 11 closed in front by two doors 12 on the back of which may be mirrors. 1

On opposite sides of the compartment 11,

between the latter-and the end walls 2, are

drawers 13, and below the compartment and the drawers are located two wide drawers 14 and 15 extending throughout the entire width of the bureau betweenthe end walls 2 thereof, and located'one above the other.

The following lockingmeans for the bottom drawers 14 and 15 are provided 1 'In a dovetailed longitudinal slot 16 in'the bottom of'the drawer 5 is slidablymounted a block 17 carrying a. combination lock, the knob of'which is'shown at18 and the bolt at 19. That portion of the block from which the bolt is to be projected is below the bot tom of the drawer, and the "bolt moves in a direction transverse of the drawer. The bolt is normally retracted flush with the side of the block, but when apredetermined combination has been worked out, aturn of theknob projects the bolt a certain distance; or,

a lesser distance if a different combination is used. I V The purpose of the bolt 19'is to depress a pair of cams 20' pivoted at 21 in a recess 22 in the top3 beneath the bottom of the drawer 5'. -Each cam 20 is connected toa downwardly extending rod 23 connected to one end of a lever24, to the other end'of which latter is connected a rod 25. The lever 24 is fulcrumed to one of theend-walls 2, as shown at 26, and to a suitable support 27 on theback or rear walll is fulcrumed'alever28 to one end of which the rod 25 is connected; The other end of the lever 28 is connected to a spring latch 29. Onelatch is provided for the drawerzl4 and another latch for the drawer 15, with a cam 20 andthe connections 7 hereinbefore described foreach latch sothat the drawers maybe independently locked one. VVhich cam is to be depressed will depend on the extent to which the bolt is projected, and as one of thecams controls the I lock of one ofthe drawers, and the other drawer lock is controlledby the other cam, the 'locks are independently controlled.

When the cams are depressed the rods23 swing the levers 24 and the latter, through the rods 25, operate the levers 28 to depress the latches 29 to which the latter are connected. The latches are normally positioned in front of the downwardly extended rear walls of the drawers, in which position of the'latches, the drawers'are held locked, but

- when the latches are forced down clear of nected to the levers 24.

The end walls'2 of the bureau have roller bearing supporting moldings 31 for facilitating movement of the drawers 14 and '15, and also ribs 32 which slidably fit in grooves 33 in the sides of said drawers to keep the latter from rising when slid in and out. The rods 23 are adjustably connected to the levers 24 by clamp sleeves 34 soas to make the action ofthe locking mechanism accurate.

Referring, now to Figs. 5to 8, the small top drawer 5 has its-rear end open, and its side walls have slide ribs. 36 to guide a slide or false drawer 37 having grooves 38 in which the ribs seat. When this double drawer is opened, all. that is visible is the false drawer 37, which latter hastwo compartments 39- for small articles wanted handy. The compartments are of different depths to clear certain mechanism in the drawer 5.

I In order that the false drawer 37 may always be. in front .and readily accessible, it is held in such position by a'spring latch 40 accessible through an opening 40 in an inclined wall 41 and acting on a keeper 42 on the inner faceof the front of the drawer 5. Whenthe false drawer is to be moved back, thelatch is released, and then the drawer is automatically drawn back by a 5 spring 43 acting on a slide bolt 44 which is held back by. aestop plate 45. When the drawer 37 ispulled forward and closed, the spring 43is placed under'tension.

The drawer 37,'when closed, conceals the knob 18 of the locking device hereinbefore described, and the knob is therefore not accessible until the drawer is slid'back to uncover the same. The floor molding' 47 shown in Fig. 8 is designed to keep the drawer 5 elevated to the proper height for the operation ofthe block 17 Figs. 9 and 10 show a device that ordinarily prevents the drawers 14 and 15 from 7 being pulled entirely out of the bureau, and

. yet permitting this when the top drawer 5 is drawn out. The floor'of the casing 6 inclosing the drawer 5 supports a downwardly extending vertical rock shaft 50 having at its upper end a laterally projecting cam arm 51. A spring 52 connected to the shaft 50 tends to turn it in a direction to hold the cam arm 51 as shownin Fig. 9. The drawer 14 (as well as the drawer 15) has a side groove 53 into which a side pin- 54 carried by the rock shaft 50 projects when the latter is given .a partial turn.

Vith the parts as shown .in Fig. 9, the drawer 5 being removed, the drawer 14 may be inserted or removed, but when the drawer 5 is inserted into its casing 6, a cam- 55 on the bottom of said drawer (see Fig.

10) engages the cam arm 51 and rocks the shaft 50 so that the pin 54 enters the groove 53, thereby. preventing removal, of the drawer 14. It will be understood-that the locking the drawer 15. V

The block 17 is provided with a handle 46 for the manipulation thereof.

Below the compartment llthe bureau shaft 50 has another pin lower down for may be-fitted with a concealed shelf 56,

which when drawn out affords a handy place for toilet articles or preparations.

I claim: 7 r
