The locker hereinvshown for'` illustrative -pur- 5 poses is :provided with side jambs l and. 8. A sheet metal door!! is swingingly mounted on the jamb 8 by-means of hinges I0. The peripheral edges of the vdoorzare bent-inwardfrom the inner face to provide the inwardly. extending anges II. 1o A siderflange II, at the. free. end-of the door, is bent at- I2 .to provide an inwardly extending ledge I3, thereby providing a three-sided recess Hl into which a-locking rod I5 is slidably arranged.,

The. lockingrod I5 .is provided WithA spaced 15 slots I6 through which rivets I1 extend. The rivets I'Ilextend through the side ange .I IA at the free end, ofA the door and have heads I8 on their inner ends. for the purpose of holding the locking rod .against the side flange II and still allow 20o for slidable movement of the rod I5.

, The-rod, I 5 is providedwithright angle project.- ing ngers I9 which are struck -out and bentfrom the rod toprovide lockingI fingers which cooper-- ate with keepers 2(1.fastened tothe jamb 1.

A door operating grasp 2I is arranged on the outer face of the jdoor. and'hasitsupper end fastened. thereto byv means of afastening member. 22.` The lower end ofithegrasp extends through a slot in the door'and has its lower end bent 30Y as. indicated .at 23, Figs. 5. and. 6..v 4Anoperating handlef..24isarranged within .the boundary of theY grasp 2l. and has a tail-piece. 25 provided atits lower end which extends through a slot formedinfthe bottom ofthe grasp 2|. A projec- 35- tionfZ isfformed on ithevupper end of the handle 24V and extends.'A through an elongatedv slot V2'I formed through the door. AThisprojection 26 alsofprojects, .through and assists in. supporting..

a plate, 28. Which is thus rendered movable verv tically upon vertical movement ofthe handle 24. The plate 28, is-provided-with inwardly extending. upper `and'` lower ilanges 29 which overlap the outer or open surface-of the locking rod Iti` as indicated at 30. Oiset upper and lower members 3| are xed-.to the rod-such as by rivets 32, and receive the anges 29 ofthe plate 28; Thus, the` iianges` 29 are received-betweenfthe outer face. ofthe rodv I5 and the inner faceof the members 3l. The plate 28rissuitably held on the inside 50 face of the door by meansof-the projection 26, and theailanges LIS-receivedbetween the outer turned ends of the members 3| and theouter face ofthelockingk rod;- |5.--..I'lf1erefore, vertical mOVement of thehand-le 24, which movement isr 55 Vdinary normal circumstances. `a key is applied to the lock 48 to withdraw the limited by the slot 21, will raise the rod I5. The rod I5 is provided with ratchet teeth 33 which are engaged by the end 34 of a spring clip 35 which is fastened to the inner face of the door. When the rod is raised, the spring clip 35 will engage the ratchet teeth 33 and hold the rod in up unlocked position so long as the door is in open or partly open position. However, during closing movement of the door, such as when the door is pushed all the way shut, the keepers 20 will strike the spring clip 35, push it inwardly and disengage the clip from the teeth 33, thereby permitting the rod I5 to drop to closing position by gravity. The construction so far described includes a handle having vertical slidable movement relative to the locking rod. When the handle is moved upwardly, engagement of the iianges with the members 3l will cause the rod I5 to be raised to unlocked position. Then, when the door isopened, the spring clip 35 will hold the rod in up or unlocked position, freeing the locking fingers I9 from the keepers 28. However, upon release of the handle 24, the handle and the plate 28 will drop downwardly by gravity.

The tail-piece 25 isprovided with an opening or hole 38 to receive the bow or shackle of a padlock when the handle 24 has dropped by` gravity to its normal position, Fig. 6. The handle 24 is thereby locked and cannot be raised. When the door is closed, however, the spring clip 35 will be moved away from engagement with the ratchetY teeth and thereby the rod is free to lock with the keepers 2D. The door will thus be in locked posithe projecting ledge 38 andprevent the handlev 24 from being raised. To open the door when it is in locked position with the rod down, and the draw-bolt of the lock against the ledge 38, it would be impossible to open the door under or- However, when bolt 39, the handle 24 may be raised. The raising of the handle, as previously described, will also raise the slidable rod I5. Then, when the door is pulled to open position, the rod I5 will remain in up position because the spring clip 35 will be in engagement with the ratchet teeth 33. In this position the locking fingers I9 will be out of engagement with the keepers 28 or in the position shown in Fig. 5. As soon as the handle 24 is released, the handle is free to drop even though the locking rod is held upwardly. As soon as the handle drops, the handle being connected to the plate 28, the plate will also drop. Therefore, the lock 48 may be locked to bring the bolt 38 in the path of the ledge 38. Thus, when the door is pushed closed, the jamb will strike the spring clip 35, cause disengagement of the clip from'the teeth 33 and allow the lingers to drop into the keepers and thereby lock the door. This construction permits the handle 24 to be locked and prevent movement thereof, but will permit the locking rod to drop by gravity when the doorV is shut. Y

It would still be possible, however, to open the locker by slipping a wire through an opening in spring 46 has an upper spring end 4l and a lower spring end 48. When the handle 24 is raised upwardly, the spring end 4'I will engage a ledge 49 on the cover plate 58, and upon such engagement, the spring will turn the trigger 4i to substantially vertical position as shown in Fig. 4. The handle 24 will then be free to drop downwardly, but the rod I5 will remain in up position.

However, as soon as the locking rod is dropped by the closing ofthe door, the end 48 ofthe spring 46 willv engage the fastening element 22 and swing the trigger on its pivot 42 to the position shown in Fig. 2 inwhich position the end of the trigger will lie immediately above an arm 5i which is bent from one of the members 3|. Therefore, if a wire or other device were slipped through an opening in the door and engage one of the fingers I8, the rod I5 could not be raised as it would strike the lower end of the trigger 43. In raised position the end 41 of the spring is compressed by its engagement with a part of the casing 5l),V thereby turning the trigger on its axis orpivot and freeing it from the ledge or arm 5I, allowing the plate to drop relative to the locking rod I5. When thedoor is closed, the spring clip 35 will become disengaged from the rod and the weight of the rod moving downwardly, will bring the nger or ledge 5|below the bottom of the trigger 4I at which time the end 48 of the spring 46 will turn the trigger so that it will lie directly in the path of the ledge or finger 5I. Therefore, when the door is closed and locked, it is impossible to raise the rod I5 or to raise the handle 24. Turned iianges 52 and 53 are bent up from the plate 28 on opposite sides of the plate to limit the pivotal movement lof the trigger 4I'.

A rubber plug 54 is fastened in position on the inner face of the door to provide bumpers or strikes Vfor the plate 28 during upwardror downward movement thereof.

Operation When the door is closed and locked, the parts will assume thev position shown in Fig. 2. The end 4I of the spring 46 will be away from the ledge 49 of the cover plate or casing 58, but the end 48 of the spring will engage the fastening member 22 and the trigger will be turned to engage the arm or ledge 5I which is xed to the rod I5. Therefore, the handle 24 cannot be Voperated to raise the rod, nor can the rod be raised independently of the handle. However, upon the insertionl of a key to move the locking bolt 38 to unlocked position or the removal of a padlock from the opening 36 in the tail-piece, the handle 24 may be raised. Raising of the handle 24 will also yraise the lockingrod I5 a distance suiicient to'permit the locking iingers I9 to free themselves from the slots in the keepers 25. The door is thus free to be opened. Upon opening movement of the door, the spring clip 35 will engage the ratchet teeth 33 and holdthe locking rod I5 in up or unlocked position. Also, upon release of the handle 24, the handle is free to Cil padlock, vazk'ey may. be inserted-in` the. lock 40 to shift-thefdraw-bolt 39 into locked position vrelative to the projecting ledge 38.' All the parts.

are thusin locked position with theexception of the' lockingl rod-l5 andv thesafetyv trigger flellf.l When.the=dooriispushed to closed'position, the

keepers '26 will strike lthe spring clip 35'and` disengage the clip from the teeth 33 1and the-rod willclrop, by gravity, to-locked position bringing the-lockingffingersf'w into locking position relativefrtosthe keepers 2B. During the downward movement ofthe locking rod I 5,' the ledge or arm Y5l-williberrnoved below the'bottom of the trigger 205s notbe opened-without the-use of a proper key.

f in unlocked position, means `for releasing saidA Theinvention provides a locking device which permits pre-locking, that is, the locks on thedoor may-belocked whilethe-dooris in its open position. ThisisA made possible due to the fact thatthe lockingdevice or locking rod operates `independent of the outside lock controlling handle. The purpose of this arrangement is that the'- loeker may bel/unlocked and thenimmediatelyv have the lockingl members locked while A the doorisfopened either by-'use of a flat key lock, apadloclg ora combination lock. It is then only necessary -to push the door closed asthe locking mechanism will then function and `therdoor will be securelylocked without any Vmanual operations. requires only the use ofl few and simple parts, and'it may be made Very economically. The lockingdevice is positive in operation and pre-- vents opening the locker door except in the ordinary normal manner by the employment of a propery keys- Changes may be made in the form, construction, and arrangement of the parts without departingfrom the spirit of the-invention or sacricing any of its advantages, and the right is hereby reserved to make all` such changes as fairly fall within the scope of the following claims: f
