cooperate with a suitable keeper in the door frame as A and comprises a main sup porting frame 1 adapted to be secured by suitable fastening means as screws Q to the outer face of t-he door A and across a port-ion of the edge thereof adjacent the frame A y The door A. is provided with a. recess or chamber a adapted to receive certain portions of the locking mechanism While the trame A is provided with a. recess or chamber r1/ for receiving the outer end ofgthe lock bolt and a suitable keeper plate The lock proper comprises relatively rotatable co-axial shaft sections --l and passing through registering ipenings in the outer plate 1 and inner side of the door A respectively so that the inner ends of cach shaft section will project into the chamber KL- T he shaft sec-tion 4 preferably extends entirely through and beyond the outer and inner faces of the door --A and across the chamber a the outer end and portion which extends across the chamber Q being angular or square in cross section for a purpose presently described, While the other shaft section 5- is preferably tubular and journaled upon the inner end of the `shaft section L1- and is extended through the inner side of the door partially across the chamber afand some distance in- Wardly beyond the door for receiving and supporting a handle 6 which is secured to the inner end of the tubular shaft section 5 by a set screw 7- or equivalent fastening means.

The inner end of the shaft section 4 is cylindrical to permit it to turn freely in the tubular section 5 and is provided with an annular groove 8 for receiving a key or pin Q by which the two shaft sections are' normally held against relative endvvise movement While permitting either to turn freely upon the other.

A suitable Wear plate l0 is secured to the inner face of the door A around the tubular section 5 to be engaged by the hub of the handle 6 for additionally holding the shaft section 5 against undue endvvise movement in one direction..

A suitable handle M is secured by a screw l2 or equivalent fastening means to the outer end of the shaft section lt in spaced relation to the outer face of the plate 1 to permit the turning of the shaft section 4.- independently of the shaft section 5 for a purpose presently described.

The inwardly offset portion of the plate 1 across the inner edge of the door A is provided with a guide opening l3 in which is movable one end M of a bolt l5 the end M of the bolt being normally extended through a registering opening in the keeper plate 3 and into the chamber af/ to hold the door in its locked position and has its inner face beveled for sliding engagement with the keeper to automatically force the bolt inwardly beyond the keeper when closing the door.

The portion of the bolt l5 within the chamber gt is widened and,l bifurcated to form opposite arms l6 having inturned projections 17 at opposite sides of and equal distances from the aXisof the shaft sections 4- and 5 E The bolt l5 is yieldinglyiheld in its locking position by means of aflat spring` 1S-having its intermediate portion engaged with the periphery of the tubular shaft section 5 within the chamber'2 a and its opposite ends bearing against the inner faces of the upturned lugs or shoulders l7 and tensioned to force the bolt to its locking position but yieldable to permit the bolt to be drawn inwardly to its unlocked position in a manner hereinafter described.

lllhe tubular shaft section 5- is provided with oppositely projecting similar arms 19 within the chamber aand adjacent the inner face of the bolt l5 for engaging the lugs lT- opposite the ends of the spring l8 so that the turning of the handle G andstubular shaft i3-- in either direction will cause one or the other of the arms 19- to engage the corresponding` lug l.7 and thereby withdraw the bolt l5 from its locking position independently of the shaft section 4- and its operating handle ll see Figure El.

A supplemental bolt operating plate 420- is reciprocally movable lengthwise of and adjacent the outer face of the bolt l5 Figure 27 and is provided at one end with oppositely projectingV lugs or shoulders El and 22 one of which projects into an clon ated slot 23 in the bolt lt some .i nnce from the a-Xis of the shaft section and is normally engaged with the 'i er en wall of the slot when the bolt its locking' position, the opposite lug Q2 projecting toward the plato l ier end of the supplemeniai plate ----2" biilurcated to forni opposite arms osite sides of t ie axis of the ons i ant 5- and liieizween of 'the bolt f as shown l arms beV provided lugs 2F- normally in siubstantially the same transverse plane as the lugs 17 of the bolt l5 when the latter is in its locking position.

A hub QG having an angular opening therethrough is mounted upon the shaft section 1 within the chamber aand directly against the adjacent end of the tubular shaft section 5 and is provided with oppositely projecting arms 27 Fig. 4,

or engaging the adjacent lugs of the plate 20- whereby the turning of the shaft section 4- by its handle l 1 in either direction will draw the plate 20- inwardly thereby engaging its lug` Ql with the adjacent end wall of the slot 23- for simultaneously withdrawing' the bolt 1.5- from its locking position independently of the tubular shaft section 5- and its operating handle 6 The length of the slot 2 beyond the lug 2l is sufficient to allow the bolt l 5 to be with drawn from its locking position by the turning movement of the shaft section 5 in either direction.

lt is now evident that the bolt l5 is automatically forced to its locking position by the spring l8 and that it may be withdrawn from said locking posit-ion against the action of the spring by the turning movement of the tubular shaft section 5 in either direction through the medium of the handle which causes one or the other of the arms 19- to engage the corresponding lug l7 ofthe bolt l5 to withdraw the latter inwardly independently of any turning movement of the shaft section 4 and its handle 1l rThe bolt l.5 may be withdrawn from its locking position by the turning of the handle 6 at the inside of the door in either direction but suitable means is provided for prcnenting` the turning movement of the outer handle ll and its corresponding shaft section -t until certain controlling elements hereinafter described have been previously adjusted to certain positions.

For this latter purpose7 a circular disk 28- is brazed or otherwise secured. to the inner face of the plate 1 and is provided with a series of inwardly projecting shoulders or lugs 29- arranged in uniformly spaced relation circumferentially about the axis of the shaft sections 1 and 5 to be engagvred by springs Q9 which are secured to the hub of a disk 30 (one of the lock-controlling disks) in a manner and for a purpose hereinafter described.

The disk Q8 and plate L are provided with registering openings co-axial wi th the shaft sections for receiving a tubular sleeve 3lwhich extends beyond the inner face oc disk Q8- and also beyond the outer ce of the plate --l and is provided on its in er end with the bolt-controlling disk aeoefiee 30- rigid therewith tor angular adjustnient with said sleeve.

A similar, but somewhat longer sleeve 33H is mounted'ior angular adjustment "Within the sleeve u3lw to extend beyond the opposite ends thereof around the shaft section. -'--i-- and is provided on its inner end with a holt-controlling disk -Serigid therewith and adjacent the inner end ci the disk 30.1

The outer end oi the sleeve -31- is provided. with an operating handle 35- by which it, together with the disk -30-, inay 4 loe adjusted rotarilylreiat-ively to the shaft section `-tand inner sleeve -33-.

This handle Ng35 preferably consists ot" a peripherally graduated section w36 and nut section -3Z'-, both of which are inounted upon the outer end of the sleeve -31-1, the section -36- being provided with a series ot internal notches -38- arranged in uniformly spaced relation circunierentially tor receiving s projection or key -39- on the periphery oi" the sleeve -'llvvliileY the .section 3T- is threaded internally and en gaged with the outer threaded end oi the sleeve --lso that loy reinoiling the nut section -37 the other section -36 may he displaced axially troni the key -39- and then turned any part oit a revolution to reg ister any one ci the other notches -38- with the lug 38' as may he required tor changing the combination oit the controlling disks.

ln like manner the enter end oit the sleeve 33 is provided 'with an operating handle ll0- surrounding the .outer end o the sleeve adjacent the outer tace oi the handle -35--- and consisting oi an inner section 4l-n and an outer section fi-2*, the inner section fil like the section -36 being provided with a` series oit internal notches arranged in uniformly spaced relation circuniferentially tor receiving a lug or key on the periphery of the sleeve w33- While the section -i2 is threaded internally and engaged with the outer threaded end oi the sleeve -33.`

The nut section 4l-2P- inay loe removed to permit the displacement of the section 4tlior angular adjustment thereof to register any one or" its notches with the corresponding key for additionally changing ythe coniloination of the controlling disks -30- and -3d-. rllliese disks 30- and -34- are disposed in the plane of the lug -22- and are provided with radial slots lA- extending inwardly -ron the periphery thereof and. adapted, when properly adjusted, to permit the unlocking ofthe holt --,l0y the liandle *lland its shaft section llto register with the lug *22 but at other times to be out ot registratien with each other and also out ot registration with said lug to prevent the Withdrawal ot -the liolt-controi ling plete and thereby prevent the 'eratine member 35- thus errnittinen the radial slots fifiin the disks and 34- to be moved into and out. oi registra tion with each other and also into and out oi registration with the lug 22M on the sliding plate -20-- rflue springs -29-- are mounted upon 'the disk 30W to rotate therewith and successively engage the ings QQ- on tl disk -Qf when the disk "30# 1s rota-t com tinuously in either direction 1n Wine case the springs will 1"oe placed under more or less tension when riding across the inner 'faces of the lugs m29, said springs heine* shown in Figure 5 as under partial tension due to the rotation 01"' the disls 30- i the direc-- tion indicated hy arrmiT 9 i igure 5.

'lhe objectoii the stop lugs -19- and their cooperating springs is to enable the operator to sense the adjustment oit the disk 30 to ditllerent positions and also to normally hold the `disk in suoli position ci rest that its slot lier- Will 'ne-out ci alineinent with the lug -22- and therehj'f 'to prevent the operation of the slide 2G-- liy the ro tary adjustment oat the handle il and its shaft --efthrough the inediuin oi the arms 21hrlhe handle sections 36" and oit the handles and 0-, respectivelyl are cylindrical and provided with neripheral graduations numbered in sequentie circumerentially from a given point as shown in augure 6 While the other sections -311"- and #-42- oi the saine handles are also cylindrical and knurled peripherally to facilitate the `angular adjustment of the sleeves -3i and *33 and their respective lock-controlling' disks -30 and 311- as may 'he required to bring the slots -fiLiinto and out oi registration with the lug Q2- 'lhe graduations onthe peripheries oithe disks 36+ and -fllare adapted to he brought into registration with a fixed. indes: or starting point *Jion the plate Ill, so that when any two previously selected graduations oi the combination are registered with the index. the slots iot the disks -30- andl *34ewill he brought into registration with the lug -22- thus permitting the slide -20- to ice operated ley the rotation of the shaft in either direction `5er withdrawing the holt -lfrom its locking positionD it the disks -30- and 3th have heen adj usted to permit the unlockingl of the holt -15- and tooth the bolt -l5- and -20- have returned to their normal locking positions, said disks -30- and rwZr-lwill be rotated by their respective handles and M-l-O- to move the slots a4- out of registration with the lug thereby bringing the solid portions of the disk in opposed relation to said lug to prevent the withdrawal of the slide -20- and bolt -l from their locking positions and incidentally preventing the turning movement of the shaft 'tand handle -ll-.

These last-named operations are, of course, to prevent the opening of the door by unauthorized persons unfamiliar with the combination of numbers on the disks HSW-- and 4lrequired to be registered with each other and with the index H45- on the plate -l- For examplel assuming that the graduated disks --36- and 41- have been set .so that their graduations -elOM and 90- are brought into diametri al alinement with the slots 14M of the disks 230- and -34- respectively, then it will be necessary to register both of these graduations 4U- and -90- with the fixed index -45- in order to bring` the slots -l4- into registration with the lug -22- to allow the opening of the bolt -15- by the turning` of the shaft flthrough the medium of its handle -1l-.

Under this setting of the graduation members M536- and 4 lif they are not registered with each other or either or both of them are not registered with the index 45- the slots 45twill not be registered with the lug -22- and, therefore, the plate -2()- cannot be operated to unlock the bolt -l5- by the turning of the handle -l1-.

lVhenever it becomes necessary or desirable to change the combinations on the disks -3t3- and -41- it may be readily done by temporarily removing the handle lland knurled nuts of the handles -35- and -40- and then readjusting the graduation members -36- and 41- to produce any other combinations of graduations within the range of the numbers of said disks.

'Vhat I claim is l. The combination with a door having a lock-receiving recess and a casing having a keeper for the lock, of relatively rotatable coaxial shaft sections extending through registering openings in the door and across the recess therein and telescoping with each other within the recess, said shaft sections having their outer ends provided with handles for rotating the same, a bolt mounted on the door and movable into and out of engagement with the keeper and normally spring-pressed into engagement with said keeper, means actuated by the turning movement of one of said shaft sections for withdrawing the bolt from its locking position, a bolt-operating plate admenace jacent the bolt within said recess, means actuated by the turning movement of the other shaft section for actuating the bolt-operating plate to withdraw the bolt from its locking position independently of the operation of the first-named shaft section, a disk within said recess and adjacent the bolt-operating plate and adjustable rotarily about the axis of the second-named shaft section relatively thereto, a lug on the bolt-operating plate extending across the periphery of the disk, said disk having a slot extending inwardly from the periphery thereof and movable therewith into and out of registration with said lug for controlling the operation of the boltoperating plate and preventing the turning movement of the second-named shaft section when the slot is out of registration with the lug.

2. In a door lock of the character described, the combination with a door, relatively rotatable coaxial shaft sections extending through registering openings in the inner and outer sides of the door respectively in telescopic relation, a handle on the inner end of the inner shaft section for turning the same, an additional handle on the outer end of the outer .shaft section for turning the same, a bolt slidable transversely of the axis of said shaft sections and extending beyond opposite sides thereof, arms secured to and projecting laterally from opposite sides of the inner shaft section for engaging and withdrawing the bolt from its locking position as the inner shaft section is turned about its axis, a boltoperating plate movable lengthwise of the bolt and provided with .means for engaging and withdrawing the bolt from its locking position when moved in one direction, means actuated by the turning movement of the outer shaft section for actuating the boltoperating plate, a sleeve surrounding the outer shaft section coaxial therewith and -rotatable relatively thereto, an additional sleeve surrounding the first-named sleeve coaxial therewith and rotatable relatively thereto, a disk secured to the first-named sleeve to rotate therewith, an additional disk secured to the second-named sleeve to rot-ate therewith, separate devices on the outer ends of the sleeves for rotating the same and a lug on the bolt-operating member extending across the peripheries of both of the disks, said disks having slots extending inwardly from the peripheries thereof and movable into and out of registration with said lug to permit the lugs to enter the slots for withdrawing the bolt from its locking position when the bolt-operating plate is operated by the turning movement of the outer shaft section. i

ln witness whereof I have hereunto set my hand this 16th day of June 1927.
