This invention relates to improvements in lockers, more especially to combination hat and coat lockers and the like wherein interlocking means are provided so that by locking 5 one door, both doors are locked.

The main objects of the present invention are to provide a simple and practical form of interlock mechanism, whereb two separate locker doors can be controlle by a single manufactured and assembled into the locker at a low cost; to provide a substantially unitary interlocking member in which joints and composite structures are avoided, and which can be made in such a simple manner as by merely bending a rod into the required shape; to provide an interlock member which is well concealed, occupies a very small space, and does not obstruct vthe locker compartments; to provide an interlock in which the force from the controlling door is communicated directly through a single member to the other door; and to provide an interlock which` is positive and reliable in operation.

Illustrative embodiments of this invention are shown in the accompanying draw- F ig. 5 `is a detailed section of the latch for the lower door and is taken substantially on the line 5-5 of Fig. 1.

lock; to provide such a device which can beA Fig. 9 is a View showing substantially the parts shown in Fig. 4 inv perspective, looking outward from the interior of the locker.

In the devices shown, a rod bent in the form of a bell crank is rotatably mounted on the locker wall adjacent the edges of the doors. One end of the rod is bent transversely to its axis to form a cam or crank arm which projects into the path of the edge of the controlling door and the other end or' the rod is bentvto form a crank arm or linger which projects into engaging relation with the latch mechanism of the companion door. The rod is rotated in one direction by means or a spring against a stop, so that the controlling door, in closing, strikes against the crank arm on the one end and rotates the interlock rod so that the finger on the vopposite end is rotated into position to prevent the latch of the companion door from being operated to open the door.

Tn the form of locker shown in the drawings, the upper portion of the lockerv 10 is divided into two horizontal hat compartments having doorsll and 12 arranged one above the other, and the `lower portion is divided by a vertical partition 13 into two vertical coat compartments having doors 14 and 15. The doors 14 and 15 are each hinged to the middle partition wall 13 of the locker, and the upper doors lland 12 are preferably hinged respectively to the opposite sides of the locker. The upper door 11 which swings tothe right controls the doorV 14 of the companion compartment at the left side of the locker, and the door 12 which swings tothe left, controls the door 15 at the right side.

The controlling doors 11 and 12 oi' the hat compartments are each provided with key operated locks, adjacent the swinging edges, which engage with the adjoining portion of the locker wall for holding the door closed; and the doors of the coat compartments are provided With tubular portions 16, in the swinging edges, in which are slidably mounted vertical latch bars 17.

The bars 17 are normally in a lowered position and may be raised by means of handles 18, which project through slots in the front Walls of the respective doors, and

the length orn the slots determine and limit the up or down movement of the latch bars.

ln closing the coat compartment doors, the latch bars 1? are raised and then dropped down to engage in the hooks in the keepers 19 which are riveted to the frame of the locker and are bent around so as to enter slots in the rear portion or" the tubes 16 wherein the keepers engage in suitably termed slots in the latch bars 17, as shown in Fig. 5. For controlling one door by another, the inter lock rod members 2() and 21 are rotatably mounted on the brackets 22 which are riveted to the angle sectioned edge frame member 23 of the locker and are positioned one on each side oi the locker. rEhe upper ends of each of the rods 20 and 21 are bent over and termed into a Jell crank cam` 2a which lies in a plane at right angles to the rotational axis of the rod. fr portion 25 of the brackets 22 may be extended to overlie the cam portion ot the corresponding interlock rod to term a stop against which the cam strikes to limit the rotational movement et the rod under the action of the retracting spring 26 which is anchored in the bracket. rlhe springs 26 are passed through the eyes of the brackets 22 alongside the rods, and hook over the edges of the brackets at one end. The other ends of springs are hooked over the laterally extending linger'portions 27 which are formed at the lower ends ot each oit the rods. The spring rotates the rod and swings the cam 24 into the path ot the edge of the control door, as indicated in dotted lines in Fig. 3, the stop 25 preventing the f rod from :further rotation. When the hat compartment door is being closed, the edge ot' the door strikes the cam and rotates the rod into the locking position which is shown in full lines in Fig. 3.

ln Fig. 2 the cams are shown as being in cooperative relation with the swinging edges of the corresponding doors, while in the arrangement shown in lig. 6 the cams 28 of the interlock rods 29 and BO are operated upon by the hinged edges orP the doors. rlhe cams 28, on the upper ends of the rods 29 and 30, are somewhat more angular than the cams 24e on the rods 20 and 21 to adapt them tor contacting with the hinged edge of the door instead of the swinging edge. Also a different lio-rm ot' stopping means which may be used is shown. rlhe end oi the cam portion 28 is extended so that it strikes against the wall or' the locker, which in this particular instance is the inner surface of the angle member 23. ln othe1 respects the interlock members are substantially alike except that greater lengths are required where the members span one hat compartment door to cooperate with the door above.

At' the lower ends, the rods are bent to form the lingers 2"? which hook throught apertures 31 formed in the rear portion ot the tubular edges 16 of the respective coat compartment doors, so as to overle the upper ends oic the latch bars 17 when the doors are closed. rllhis prevents lifting the bar 17 to unlock the lower door until the corresponding control door is open.

ln using the locker, the hat compartment door is first unlocked with a key. When the door is opened, the interlock rod is released and is rotated counter-clockwise as shown in the plan sections, Fig. 3 and Fig. 7, into the positions indicated in broken out lines. rllhe linger 2'? is thereby withdrawn "from the aperture 3l so that the latch bar 17 may be lifted to disengage from the keepers 19 so that the coat compartment door may be opened.

ln closing the locker, either door may be closed first, and the hat compartment door may be closed and locked bei'ore the corresponding coat compartment door is closed, but when the latter door is then closed and latched, it cannot be opened until the hat compartment door is open. lf the hat compartment door is closed lirst,'the interlock member is rotated into engaging relation with the upper end of the latch bar, and the bar will strike against the linger when it is raised to pass over the ends oit the keepers in closing the door. But the upper end of the latch bar is made somewhat flexible so that it can yield sufficiently to allow the door to be pressed shut, and will then spring under the linger 2T when the bar is shoved down to latch the door.

Gbviously, a very simple lorm of interlock is provided. rlhe interlock member is made entirely or" one piece which can be manufactured, by simple bending operations. lts operation is positive; the constnfuction is simple and rugged; the interlock occupies very little space in the locker and is easily installed.

Although but two illustrative e-mbodiments of this invention have been herein shown and described, it will be understood that numerous details of the constructions shown may be altered or omitted without departing from the siprit or' this inventionl as delined by the following claims.

l claim:

1. ln a locker having doors having latches, an interlock rod mounted for limited rotation in the locker wall, the rod being bent into an arcuate laterally projecting portion, and resilient means for rotating the rod to one limit so that the arcuate portion projects into the path of the edge ot one door whereby the rod is rotated when the door is closed, the rod also having a bent portion which is adapted to engage with the latch of another door.

2. ln combination in a locker, a door having a lock, and a second door having a slidable latch bar, a bell crank rod rotatably mounted in the locker having one `crank arm engageable by the first door and rotatable thereby so that the second crank arm is in engaging relation with the latch bar of the second door.

3. The combination in a locker, a door having a lock, and a second door having a movable latch, a bell crank interlock member rotatably mountedvin the locker, a spring for rotating the bell crank to swing one arm into contacting relation with the first door so that when the first door is closed the bell crank is thereby rotated against the pressure of the spring to move the second arm into position to prevent the latch of the second door from being moved to unlock the door.

4. A locker having two compartments with separate doors, a lock for one of said doors, a latch for the other door, and interlock mechanism comprising a bell crank ac` tuated by said one door for preventing the unlatching of the other door, whereby the locking of one door will secure both.

5. A locker having two compartments with separate doors, a lock for one of said doors, a latch for the other door, and interlock mechanism comprising a bell crank comprising a rod extending` between and adjacent said doors and having transverse crank arms at its ends, one of said arms being p0- sitioned to be actuated by said one door and other arm being positioned to move into and out of position to prevent the operation of said latch.
