, . .
horizontally arranged lock rod member is rotatably ~upported in , the idewalls of the drawer channels. A crank member is mounted on one end of the lock rod and a lock bar is vertically and slid- ~-ably mounted in one sidewall of the drawer channels. The crank on the horizontal lock rod member rotatably engages with the vertical lock bar and the lock cylinder on a lock engages with and rotate~
the lock rod member thereby rotating the crank and raising or lowering the lock bar. A locking stud attached to the lock bar engages with a lock bracket on the side of the drawer to prevent - outward motion of the drawer. Advantageously two vertical lock ~ -bars are used, one on each side of the drawer or drawers to be locked and the lock bars are actuated by cranks at each end of the - lock rod. The number of locking studs located on the lock bars depends of course, on the number of drawers located in vertically stacked configuration in a desk or file cabinet.
Referring specifically to Fig. 1 of the drawings, a three drawer filing cabinet 10 is shown in a perspective view with a drawer locking sy~tem embodying the invention installed therein.
It can be appreciated that the locking system can be used in - filing cabinets with only one drawer or with two or more drawers in vertically stacked configuration or it can be used for locking drawers of desks or other types of cabinetry.
The locking system illustrated in cabinet 10 attends to the simultaneous locking of three drawers 11, 12, 13 slidably located in drawer channels 14, 15, 16 respectively having sidewalls 17, 18. A horizontally ar~anged lock rod member 19 is rotatably .. -- 2 --.. .. .

attached to the lock bar 26, when the lock bar 26 i8 moved down- ~ -wardly to the locking position, all of which arrangement is the 10 same as that associated with the sidewall 17.
In Fig. 1 a por~ion of the front of the drawer 11 is broken away to give a clear view of the locking stud 29 which engages with the locking bracket located on that drawer (but not ~ - ~
shown in Fig. 1). ~ -A detail view of the arrangement of the vertical lock bar 22 in the sidewall 17 is shown in Fig. 2, which i~ a sectional view through line 2-2 of Fig. 1. The lock bar 22 is advantageously .
slidably contained in a vertical channel member 30 (shown also in Fig. 1) which is contained in and attached to the s idewall 17.
The channel 30 has vertical slots 31 (only one being shown in Fig.
2) through which the locking studs 25 project. Shoulder portion 32 on each of the studs 25 outside the channel 30 holds the lock bar 22 cloBe to the wall of the channel 30 and provides for even movement of the studs 25 up and down in the slots 31 and of the lock bar 22 inside the channel 30. Attachment of the locking c bracket 24 to the drawer 12 is clearly ~hown in Fig. 2 and the locking stud 25 is shown in locking position seated in receiving slot 33 in the bracket 24.

~038920 attached to and removed from the bar 22 by U8 ing a ~crewdriver on slotted head portion 35.
The head portion 35 is seen to have a greater width than the width of the receiving slot 33, thereby preventing substantial lateral movement of the side of the drawer 12.
The locking Qystem of the invention is seen to be made tamper-proof by inwardly projecting shoulder portion 36 of the channel 30 which blocks direct access to the locking bracket 24 or the locking studs 25.
The opposite lock bar 26 is seen in viewing Fig. 1, to be contained in the same fashion in a channel member 37 having vertical slots 38 therein (one being shown through the broken-away portion of the drawer 11) through which the locking studs 29 pro-ject and in which they move vertically. Receiving slots 39 for the locking ~tuds 29 in the locking brackets 28 are also shown in Fig. 1.
In Fig. 3 an enlarged exploded view in perspective of the upper portion of the locking system embodied in Fig. 1 i8 shown.
Tho lock rod 19 is shown to be of cylindrical configuration with 20 axle members 40 (only one being shown) at each end thersof. The axle member6 40 are rotatably supported in the sidewalls 17, 18 ~uch a~ in plate member 41 attached to the channel member 30. The lock rod 19 is shown as having a bracket portion 42 centrally located thereon with a slotted portion 43 therein and the lock cylinder 21 ha~ an actuating pin 44 outwardly projecting therefrom, the pin 44 being ~lidably engaged with the slotted portion 43. The crank member 23 has a pin 45 outwardly projecting therefrom and the lock bar 22 has a slot 46 therein, the crank pin 45 being engaged with and rotatable in the lock bar slot 46. The arrange-1~389zo ment with the crank member 27 and the lock bar 26 is the same onthe other 5 ide of the cabinet 10.
In order to prevent disengagement of the lock bar 22 from the crank pin 45, a bulged portion 47 at the top of the lock bar 13 near the crank member 23 is provided which prevents the lock bar 13 from being sprung outwardly. A similar bulged portion 48 is shown in the other lock bar 26 and these bulged portions 47, 48 are clearly shown in hidden outline in Fig. 1.
Operation of the locking system of the invention can ea ily be followed with reference to Fig. 3. Upon insertion of a key in the lock 20 the lock cylinder 21 is turned, thereby swinging the actuating pin 44 downwardly. The pin 44 alides along the slot 43 and at the same time rotates the rod 19 so as to swing the crank pin 45 downwardly. ~he crank pin 45 slide~ backwardly in the slot 46 and at the same time forces the lock bar 22 downwardly. The downward motion of the lock bar 22 re~ults in engagement of the locking studs 25(see Fig. 1) with the slots 33 in the lock bracket~ -~
24 of the drawers 11, 12, 13, thereby locking the drawers in place.
A similar action occurs in the sy~tem on the other sides of tho drawers. Unlocking of the lock turns the actuating pin 44 up- -wardly and reverses the proces~, thereby releasing the drawers.
It can be appreciated that the rotatable lock rod 19 could be located at tho bottom of the cabinets below all the drawer~ or between two drawer~, if dosired, raising and lowering the lock bars 22, 26 in a ~imilar manner. Furthermoro, the horizontal lock rod could be extended across two or more vertical sets of drawers with vertical lock bar~ being actuated by the rod on the R ides of each of ~he set~ of drawer~.
