To all` whom it may concern: f

Be it known that I, DURAND` GHUiicHiLi a citizen of the United States,i'esidiiig at Chicago, inthe county of Cook and State of Illinois, have inventednevv and useful lintime will be rigid and securely hei-d by said lock from being pried openwhen closed.

lith a view to the attainment of.tli.ese ends and the accomplishment of certain other objects that will hereinafter appear, the invention consists in the features of novelty which will now be described with reference to the accompanying drawings, and n iore particularly pointed out in the claiins. In the said draWings-.lligure 1 is a front elevation of'myimproved leek on a locker door, showing the same closed and partially broken aivaytFig.' 2 is an inside elevation thereof; Fig. 3 is an enlarged plan section ofI one corner of the door and connected parts on an enlarged scale the section being taken on the line 3, 3, Fig. 5; Fig. .er is an enlarged plan section on the line t, t, Fig. 6; Fig. 5 is a front elevation of the parts shown in `Fig. 3; Fig. 6 is a front elevation of the'paits shown in Fig. 4; and Fig. 7 Ais an enlarged plan section taken on the line 7, 7, Fig. 2.

1 is the door proper, which' is formed of thin sheet inetalnd provided around its edges with flanges 2, 3, 4, 5, Which are constituted by turning` up the edgesof the sheet and securing :the ends of the flanges thus constituted by `ineaiis otrivets-G, orother suitable devices. f Riveted or otherwise secured tothe door parallel with and contiguous to the flange 2 is a' rod 7,' which -is preferably square, and has its ends provided with )ournals or pins 8 and carried through the top and bottom flanges 3, 5 and journaled` in blocks 9 secured aboveand below the door, one of .these blocks being secured to the bottom crossbar 10 and the other to the top i\cross bar 11, which constitutel the upper and lower ends of the door frame. By these nieans the door is securely joiirnaled or hinged and the edge of the door from end to end is braced by the rod 7, making it practically impossible to bend the door and spring the hinged pintles out of their seli'- -f i 'lt desired, similar rods 12 may be riveted along the upper and lower edges of '65 the door for stitlening the door in a longie tudinal direction.

On the edge of the door oppositethe hinge red 7 is mounted a vertically sliding bolt rod 13, which is secured in place in any suitable way, as by straps 1-'1 rivetedor attached tothe inner face of the dooi. This.

bolt rod 13 extends throughout a substantial portion of the height of the'door, and is provided at its upper end with a bolt15 projecting laterally therefrom and' at or near vits other end with a siniilaigbolt 16. y

These bolts are substantially the ysame in4 constructioi'i and they extend laterally -a'- sufficient distance to project across the outer flange 17 of an upright angle ironarraliged at one corner of the locker'ivith its upper and lower ends attached'to the bars 10, 1-1 and constituting the-side of the dooil frame, so that when the bolts 15, 1G are behind the flange 17 as shown in Figs. 1, 2 and 4, they will prevent the door from being opened. The bolt rod is held against rotation beyond acertain degree, by a staple 18, which projects through an 'aperture or slot 19 iii the door 1 and is arranged contiguous to a companion staple 2O,4 which is carried through the face of the door 1 and secured by a rivet v2 1 to side flange ffl. Thus when the staple 18 is opposed to the staple 20, the rod 13 is held against rotation and the door isfconsequently bolted at top and vbottom by the bolts 15, 16. This rotary movement of the rod 13 is also prevented by a knob vor handle 22 secured to the'rod 13 and projecting through a slot. 23 foi-ined vertically in the face of the door, Abut the upper end of this slot is formed with an offset or notch 24 so that the'rod 13 may be lifted by means ot the 'knob 22 until the staple. 18 passes.

posite notches or apertures l25,/'26 respee )3 0E tively, formed iii the flange- 17 and-thus allow the door tobe opened. When the I i hook engages.

` Within' the locker and consequently a condoor 1s closed again the-jar dislodges the staple 18 from'the stapleQOand the-rod 13 drops and carries the bolts 15, 16 behind the'lange A17 as before.

In order'that the rod 13 may beilocked against' vertical movement for preventing the door irom' being opened, a padlock, not

necessary to illustrate, may be passed through thelstaple 18, 20, or, if desired, the door may hepermanently provided with any suitable :permutation lock27 having a bolt 2S adaptedtmpass Vthrough the staples 18, 20. In vaddition to this lock or as a. substitute for this, the door may be provided with a keylook 29, having a' bolt 30 adapted to engage overa lug 31 projecting from the rod ,13, and thus prevent the rod from being litted.

"When the bolts 15, 16 enter their respective notches 25, 26 and fall with the rod 13, they engage between the flange 17 and

tu'o straps

32, 32 respectively, which are riveted 'orotherWise secured to Vthe inner tace of tlangeel'?, and the ends of the bolt 16'- are provideijllA With hooks or bends 34, which are constructed and arranged that should it be attempted to pry the door avvay from the flange. 17 thehools will engage the straps 32,'32and prevent the bolts 15, 1G frombeing dislodged from behind the flange 1,7. This prying action of the door is furtherresisted by' hooks or catches 35 riveted oliotherwise secured to the inner face ot' flange 17,l and as more clearly shown in Fig. 7, engage around thefflange 410i the door when the door is closed. -It desired,y these hooks 35 may also be utilized as catches for holdingthe door ffrom swinging open a'ccidentally'when unlocked, by providing the flange/1 lWith bosses `36 opposite each of the hooks 35, and with The opening nrovement of thedoor Ymay lie-limited, if desired, by a stop 37 secured to angle' iron 38,A Which, together With the angle irons or bars'lO, 11 and 17, completes the door frame. This stop 37, it Will be seen, isl so close tothe plane of the locker as not toV be objectionable', and at the same time itis a Asufficient distance from the axis of the 'hinge to be effective in stopping the door. This is because the hinge is situated siderable distance from the plane ,of the Vouter face or front of the locker, and it is also situated a considerable distance laterally fromthe edge of the door trame, as shown in Fig. 3, thus leavingl a space bctween the angle iron 3S and the face of the door when the 'door is open, but when it is closed this space islled or closed` by that portion of thevdoor which projects beyond the! hinge and towardl the angle iron 38. Not only does this arrangement enable meto provide a door With a neat and effective' Stopffor checking its opening movement, but

rwhich the-point of the it locates the hinge entirely Within the locker and protects 'the' hinge pintlesfrom the possibility of vbeing driven out or dislodged from their sockets 9. The closing or inward `moveinent of the door at the opposite edge is prevented or stopped by the hooks 35 as Well as by the straps 32, which receive the impacty of the bolts l5' as the door closes, and thereby throws the staple 18 ott the staple 2O inthe 'event the jar should not be sutlicient to do so.

Having thus described my invention what l claim as new therein and desire to secure by Letters Patent, is:
