This invention relates to improvements in lockers, andmore particularly to the construction and the arrangement of the interlocking means for controlling the locking of one door by the operation of another door s as in garment lockers where separate hat and 1 coat compartments are associated in pairs. In such lockers a key is provided for only one of the compartment doors which, when closed, holds the door of the companion compart ment locked.

.The main objects of the present invention are to provide a simple form. of interlock means for interconnecting the doors; to provide an interlock which. maybe operated eitherby theouter edge or the hinged edge of the door; to provide an interlockwhich may be easily installed in the locker and which is verystrongand durable in use. Two. illustrative embodiments of this 'invention are shown-in the accompanying drawings, in which: V p

of a locker showing ,a section taken on line of- I the Wall- .of the frame.

The locker is preferably of sheet metal and 14, extending from the lower transverse mempartments arelikewise respectively fitted with 1 doors 17 and 18 hinged to the marginal frame 11 at opposite sides, so that the upper door 17 which is related with the lower door 15 swings to the right to open, and the upper door 18 which is related with the lower door 16 swings to the left to open.

Theupper doors 17 and 18 are each provided with key operated locks for locking the swinging edges of theidoor toe-the adthan the bar 19, shown at theleft, because it joining portion of the marginal frame; and

must. spanthe door 18 which is related with the coat door 16. In other respects the interlock bars are identical and a description. of

As is shown more clearly in Fig. 5, the up per and lower ends of theinterlock bars have} flanges 21 which are slotted to receive sup,-

porting posts 22 whichv are rigidly carriedby. angle clips 23 riveted to the outer frame 11.

The interlock bars are normally held in a raised position by means of a coil spring 24, which is anchored to a bracket 25, secured to Means are provided forfsliding the bar downwardly against the action of spring when the upper door is closed,.which consists of a cam or lug 26,. in-

tegrally formed on the upper end of the locking bar, which is engaged by the edge of the corresponding hat door; ;At the lower end the bar'is bent; inwardly to provide a lug or finger 27 forengaging withthe latch bar 28 of the lower-door.v 1 In Fig. 2 the cam 26 is shown as cooperating with the hinged edge of the upper door 18;

but it may be arranged to cooperate with the Y swinging edge of a door, as is shownin Fig 6, as will be described hereinafter. The upper doors are of sheet -metal construction,

with the flange 30 projecting. inwardly aroundtheledges, :which'is slotted as at 31,

see Fig. 8, to receive the cam portion. It will now be seen that when the door is swung closed, the sloping surface of the cam is engaged by the upper side of the notch, and the interlock bar is thereby cammed downwardly and held in that position.

The lower doors 15 and 16 are also of sheet metal construction, and the metal is bent around to form a tube 32 at the swinging edge. In this tube is slidably mounted the latch bar 28 which extends substantially the length of the door, and is provided with a handle 83, that projects through a slot in the front wall of the door, so that the bar may be manuallyraised or lowered, the movement of the bar being limited by the length of the slot. Hooked catches, or keepers 34, are riveted to the outer frame 11, adjoining the swinging edges of the doors 15 and 16, and are bent into U-shape so as to project through slots 35 in the rear wall of the tubular portion 32, as is shown more clearly in Fig. 9. The latch bar 28 is slotted at'36 to receive the ends of the catches 34, as shown. The latch bar is cammed upwardly by the outer sloping end of the catch 34 whenthe door is being closed, and drops down by gravity into engagement with the hookin the catch to hold the door closed.

In Fig. 6 the interlock bar 38' is extended so that the cam 39, on the upper end, is engaged by the swinging edge of the top door 17 instead of the hinged edge of the door 18 as shown in Fig. 1. The cam 39 enters and is engaged by the upper side of the notch 31-in the flange of the door. In this form the cam is formed by bending over the upper end of the bar, while in the form shown in Figs. 1 to 5 the metal is bent out atthe side. In either form, a sloping cam surface is provided for performing the function of depressing the 100k bar.

At the lower end, the bar 38 is provided with the finger 27, and the bar is slidably mounted on the locker wall in the same manner as described for the bars 19 or 20.;

As will be seen in Fig. 1 and Fig. 9, the finger 27-on the lower end of the interlock bar is in close relation with the upper end of the latch bar 28 when the door is closed and thebar is in the down position. This, of course, prevents lifting the latch bar of the lower door as long as the corresponding up per door iscloscd and holding the interlock bar down against the action of the spring 22. When the upper door is unlocked and opened, the lock of the lower door may be then operated to open the same.

In closing the locker, either door may be ;.closed while the other is open. If the coat compartment door is closed first, the interlockbar is in the raised. position, under the action of the spring 24, and the finger 27 is raised above the upper end of the latch bar when the bar is, lifted: topass over the ends of the keepers 3%. The latch bar is then shoved down to lock the coat compartment door, and when the hat compartment door is closed, theinterlock bar is cammed downwardly and the finger 27 is lowered and prevents the latch bar 28 from being lifted until the upper door is again opened.

In case the hat compartment door is closed first, the end of the latch bar when raised will strike against the finger 27, since the interlock bar is then in the lower position.

The upper end of the interlock bar is flexible and will yield suiiiciently to allow the door to be pressed shut. Then when the latch bar is shoved down to lock with the, keepers 34-, the upper end will. spring into place under the linger 27.

It is now manifest that a very simple and practical form of interlock has been provided. The interlocking parts are easily mounted in place in the locker; they occupy a very small space and do not interfere with the use of the locker; and are not easily damaged or broken.

Illustrative embodiments of this invention have been shown and described, but it will be understood that numerous modifications and alterations may be made without departing from the spirit of this invention as defined by the following claims.

I claim:

1. In combination, in a locker having two doors, an interlock bar slidably mounted on the locker, said bar having a cam surface which is engaged by one of the doors to slide said bar into position to interfere with the operation of the latch of the otherdoor to prevent said other door from being opened, and a latch forsaid other door.

2. In combination, in a locker having two doors, one of which has a latch, an interlock bar slidably mounted on the locker and adapted to interfere with the latch'of the which is engaged by the other door in closing so as to slide the bar into position to prevent the latch on the one door from being operated. 3. The combination in a locker, of a casing, two doors hinged on the casing to swing outwardly and arranged one above the other, a keeper mounted in the casing'adjaccnt the swinging edge of the lower door, a latch bar slidably mounted on the swinging edge of said lower door and downwardly movable into cooperative relation with said keeper, an interlock bar slidablymounted on the casing and normally raised, said upper door and said interlock bar being provided with cooperating surfaces whereby when the door is closed, the interlock bar is moved into position for locking relation with said latch ing sheet metal doors in superposed relation,
