tively, said keepers being mounted on the door [casing in the usual'man'ner and which. keepers in this'instance project into the plane of movementofthe door Iso as to ac as stops to limit the closing movement "or the door and to causethe ends of the bolts 5-6 to .alin'e properly with the openings in the keepers 11-12 when the door is closed.

1 Obviously, 'bypturning" the handle 4,] the are employed with comparatively thin doors, such as used forsteel lockers for example,

much difiiculty isfound in providing a' comparatively simple-"and inexpensive yet cffec-tive and durable locking device to lock the loc ing devices in the'door locking position, but by-my improvement hereinafter do: s'cribed,, I have been "able: to provide such a lockingrneans which I have found satisfies all conditionsin' a most 'efl'ectivemanner.

'l lB-representswhat I will term the'lat'oh looking member; Inthe preferred form this member l l'is hollowed out, by being struck up from sheet metal,fso as to provide a rounded locking @115 which forms a lock"' ing abtitment. One side of the member 1,4:

' is'fiattened as at 16 to provide clearance for the latch hub when the door is to be unhub :ofthe-latch member 2 is cut away, prefera bly on an arc, and as shown is provided with an -up-turned lip 17 which forms a broad bearing-faces The latch locking member'14c is mounted onthe inner end of a key controlled-rotatable plug 18, the end of said plug being squared or slabbed ofi', 'for' example as-shown in.Fig..5, so as'to project into a c'entralpassage inthelocking member j 14.; Thispassage is provided with one or more stop shoulders 19 19 (Fig.- .7) ,whereby the end of the plug 18-maypartake of a d( ee'Fig-'2)" The rearside of the 7 Y limited free rotary movement beforeit starts tovturn the locking membernll. The. plug 1 8-may :be the usual key-plug suchgas round I f in, a pin cylinder lock whereby: the same may be operated byithe usual flat} key designed toractuatepin tumbler s'. :'20 represents the cylinderwportion ofthepin cylinder .lock which may .be provided with offsets 21%21, wherebytheeylinder maybe securelyrivted tQi'zi he-l idecofythe door; 1,5; 22 is. Ia i oiist no i from the cylinder 20 in which the usual pin tumblers or followers are located, which offsetin. this particular instance performs an a dditionali-function, namely,. the function of a stop to limit the turning movement of the latch locking member 14. On the inside of the latch locking member are two lugs 'hen the-member 14 isturnedin one direction the lug 23.,will.strike against the offset 22 and check the further rotation of the memberliin, that direction, at which timethe squared end .of theplug 18 will bear against one of theshoulders l9 and willbe causedtostop in a position to permit the key to be withdrawn .orinserted. When the plug 18 .is turnedinan opposite direction, it'will turnidly for about one-quarter. of a turn \whereupon the squared-end iwill-,pick up the shoulders-muse that the continued rotation of the plug by the keywill rotate the member. 14 until the other lug 24-Sl11'lk against. theaopposite side of the stop 22-at \vhichtimethe key-.plugwill again be positioned .so that. the key ,may be-withdrawn orinserted. '.Theqmember -14 may be held on theendof the plug by any suitable-means, such as a. washer .25 and .a pin26 .The operation of the device is asfollows: Then the -parts. stand, asshownin Fig.1, the ,door locking devices 2, 5,.6arein position to lock the. door closed, (-andi-the ;latch locking-member. likeWisestands .in a .position to prevent the .opening of the door locking devices, that is ,to say, the locking device 14 .is projected ,against,or.close to, the rear side of the hub ,of the latch so that anysattempt toturnthe hub will be blocked by theengagement of. one or the other end of the abutment 17, against the adjacent, part of the member 14. If a key is inserted. in the plug of the locl; and turnedin. a counterclockwise direction (as viewed in; Fig. 1), the plug will partake of a free movement formic-quarter of a,rotation, at which time the squared end of the 'plug'will pick up the shoulders 19 .so that a'continued' rotation of he-plug for three-quarters of a turnwill cause a corresponding turning movement of themember 14 leaving itfinally in theposition indicated in-Fig. 2, wherein the-key maybe removed. In the first position shown in Fig.1, the lug23 bearsagainst one side of thestationarycoifset 22. TllVhen,however, the member :14 has-been turned tothe position showniin 'Fig. 2, the .lug 24: will be brought to and againstthe-opposite side of the offset 22 thusstopping the turning movement .of the member 14' in the'position shown in Fig.2 inxwhichithelsqu'ared ofi side of theniember 1 L lies to the rear of the' hub of the latch 2 ..so. that the latter mayxbefreely turned by the handle @f'for the purpose of opening Candi closingthe door 1. I I, I Eromlthe foregoing, it] is apparent that theflooking means is" of an -exceedingly-'simple character all the parts of which may be economically produced and easily assembled,

and iyet when assembled -said devices I afford a maximum degree of. security. Il'rWill also be observed that there is comparatively nothing to get out of order and to require hold. theslocking member lat on the plug in such a way that there is no lost motion or capacity for independent relativev movement and-to that endslmay provide in some' instanees,.a,locking member snehas indicated at 14?,Fjgs 8, in which the central opening through which the irregular. end of the, plug 18%passesis shaped to said'lirregular end. or otherwise connected therewith, so thatthere will beno free movement.

.I- thewpreferred construction the lock ng member ,16' is drawn up: from a single; piece of 131. 8%; metalwithv the rearwardly flanged edge integralawith .the face so that; it will furnishjnot 1 only. a broad bearing 7 face for engagement with ,the hub abutment shoulders whenthedoor; isoto be: locked, but will withstand efl ectivelyl heavy pressure. :While I-have shown .and described the preferred form of my improved locking means, it should, of course, beunderstood that various modifications in the particular design, construction, and arrangement :of parts may be resorted to Without departure from" the spirit -iandscopeof my invention.
