John B. Fr eysinger, Hamden, Conn., assigno1-y to Sargento@ Qomnony, New Horen Conn-i o oor.-

poration of Connecticut bolt designed tobe appliedto the facesof the door.

andinserted atleast in part through a bore transverseto that which receivesthe lock case. thelock case is mounted a partofthe actuating mechanism for the bolt which must vloe suitably engaged with'cooperatllng mechanism actuated by theknobs and-not included ,in theibolt case. Itf-,very often occurs thatas vthese two sets of mechanisms are mountedV separately-.upon the:

door and in openings made at 4right angles toeach other. they arenot secured i n their vproper relative.

positions and, therefore; the .par-ts; bind and do not .Work properly. This often. is ,a result of .the

fact that the knob spindle is not accurately placed at right anglesto. thedirection ofreciprocationyof the bolt, but may also be due to other errorsin the` mounting ofthe parts.

Asthe entire lock mechanism embodies atleastv two separate parts which are separately mounted4v upon the door, it is desirable that a firm and rigid connection between these parts be secured vsuch that proper relative positioning and alignment of Y the cooperating mechanism will be obtained. In the lock shown in the present application, I provide a casing for the bolt mechanism-of generally cylindrical shape whichmay be inserted through the edge of the door, and also provide .a casing for the knob mechanism Whichvmay beinserted through an opening transverse to the opening which receives the bolt, and provide in the knob mechanism casing an opening to snugly receive therear end -of the bolt mechanism casing, thus insuring that the two casings will stand at the proper angle to each other so that thecooperating parts will enjoy a free movement Vwithout binding.

Additional means are provided for securing the two casings together in a ccnvenientmanner which which will prevent displacement thereof and which may be readily engaged during the installation of the parts. Also, the knoblnecha-vl nism is vprovided in two units orsections which may be conveniently mounted from opposite sides of the door and which, at the saine time, will con-E tain all vof the necessary mechanism .desired in locks for any of the usual situations.

One object of the present invention isto provide to employ Z. a door loci; of improved construction whicn may be readily applied vto. a door.4

Still anotherv object .of Athe invention is to provide a tubular lock of improved construction such that 'the ,.part s therefor may be mounted upon ,a doorthroueh botsor openings. 'at righi angles to.. each other and interengaged to provide a rigid connection ,between the parts whereby theI lool:4 mechanism will operate without binding A still furtherobject of the invention is to provide a door lock of novel and improved construetion, sc that, when mounted upon a door, all parts will beheld xin proper. alignment.

Still another. object of the invention is to provide a door lockbi thetypedescribed having prayed ,means for V'clogging y.one of thehkriohs against rotation. l

To these and-other ends theinvention consists; in the noi/fel features and combinations of partsto be hereinafter described and claimed..`

'invoniiorfa I howtoV Shown o look .mounted 21119911.. a .door the do o r having a cylindrical .bore `II entering through the edge thereof, and Va transfl verse bore. l2 extending fromone ,face to th e other.

Inthebore ll. is mounted a lock case l3 of substantially. cylindrical form, and reciprQ- cably, mounted the 'caseis the usual late hbolt. I4 and guard bolt I5. Rotatably 'mountedin the .caseare a pair` of`rollback hubsi 6, ar 1 d l1 compression spring 24 to normally hold the dog ging member 22 in its inoperative position* as shown in Fig. 10. As shown in Fig. 1l, oneend of the dogging member projects throughan y opening in the case to be engaged by a cooperating element hereinafter described, and thus being moved inwardly against the tensionof the spring 24. Also, as shown in Fig. 11, thelock case is provided with a slot 2B, the function of whichwill ,appear hereinafter. It will be understood that the:rollback` hubs ls and/s1 are provided with polygonal or `rectangular openings 21"f.or *they reception Aor knob spindles to be hereinafter described. l

j The casing I3'may be referred to as the casingw ofthe bolt mechanism, and mounted in the transverse bore I2 is 'a second casing 29 vwhich may bereferred toas the casing for the knob mechanism. The casing 29 is, as shown, of generally cylindrical shape but is provided with a .reduced portion atone end, thus leaving a shoulder 3`I Vbetween thisv reduced portion and the mainbody portion of the casing. The latteiiis 'p'rovided'with registering transverse openings 32 within which'the bolt' casing 'I3 issnugly received, so that, as shown in Fig. 1, the latter extends entirely through the knob mechanism casing when the parts are' assembled, and thus the' two casings will be 'rigidly heldin their proper relative positions- The `entire. knob lmechanism is divided into twopa'rts, one of which comprises'the casing 29 and certainv mechanism assembled therewith as shwnin Fig. 2, while the other parts comprise the .inner knob` end .certain mechanism 4associated -therewith asshwn in' Fig.v 7,' these two parts or sections" being' 'inserted from opposite sidesl of the"`door"vfhen the'lock is applied as will be described hereinafter.'

Within the outer portionof the" member 29 is a cup-,shaped l member 33` within which is lrrountfd"A a block 34 of cylindrical shape. A short sleeve 35 lis Vinserted in Van opening in the buasel of the cup-shaped member 33 and the end spun Vthereover to .secure'these parts together, this"sleeve acting l'as' `a bearing' sleeve for the knoblv shank 36 rotatably mounted within the sleeve '35 and held in place by a split washer 31. The knob shank is provided with a. reduced end portion 38 which passes through the cylindrical block 34, and this portion of the shank is pro-' vi'ded with a square vopenin'g39 for one 'of knob spindles. e n

'O'n` the o'ute` end ofthe knob shank 36 issecured the outside knob 40, and contained within thi'sknob is akeyfoperated lock v,4I of any im-v the proved form, thislock being provided with a rotatable key,` barrel or plug, 42 extending into an opening' in the outer en'd of the knob shank. At itsfinner end, the key barrel is provided with a reces'sf43 closedby a cap 44 provided with a slot 45,.'the purpose of which is described hereinafter, tli cap being held in place by a sleeve 46 secured to [the key barrelv by the pin- 41'.

A'ose 'member 48 is threadedly connected at' ofi the rose.

49 to the outer portion of the case 29, the threaded connection providing means for adjust` ing the rose longitudinally of the casing 29 to compensate for doors of diierent thicknesses. When the rose has been set to the proper position, it is releasably held in place by means of -aplunger 50 (Fig. 12), the pointed end of which may Vengage in one or a number ofindentations or serrations 5I provided atv the inner periphery As shown more especially in Figs. land 2, the plunger or detent 5I] is of L-shaped forin'fand is provided with a bent end 52 slidably disposed in an opening 53 in the member 34, the detent being urged into engagement with the rose The mechanism above described is all assem- 'bledi'v'vithfth'e'lcup member 33 which is thereafter inserted into the outer end of the cylindrical casing 29' and secured in place by means of the screw 56 passing through openings in the casing 29"an'd'v cup member"33 and threaded into the block 434. ,Thereafter, the rose 48 may be threadedL upon the casing 29. Thus the` outsideV knob mechanism may be readily' assembled withfthey ca`s'ing'29 before the latter is'applied to thedloor.

Also, a part of the inner knob mech'ani's'n'i'isA assembledwithin the casingf29 before it is ap plied tojthe door as shown in Fig. 2. A sleeve" 51 is rotatably mounted in the reduced end'3Ilv of the casing 29, this sleeve having an annular" ange` 58 abuttingthe shoulder 3|, and a-block 59 is mounted in the casingf29 against the flange 58, this blockbeing -provided with va centralopening 6l] and being held in 'place by a screw- 6I '(Fig. l-'inserted'through the casing 29. Al retaining' diskf62 `is secured to the' block59, thls disk closing the inner endof openings 63 and64 provided in the dblo'ck. In th'e opening y63 is a spring"65f-acting against the bent end of! an Lashaped detent or'plunger 66 similar to the plunger 50 previously described. In4 the" open ing-Ellis slidably mounteda plunger 61 whichi` serves to r`actuate the dogging membert'22,,this^- plunger having" a reduced end. surrounded vrby a 'i spring 68 and which endlpasses Fthroughffan: opening 69 in the disk 62. Rotatably carried by the b'ody of the plunger V61 in anv antifriction= roller 10.'` v .l x 'f The block 59 is provided with a recess 1I which registers with a rrecessv or` slot 12 in the disk 82,-', and slidablymounted in the recess1I is a lock-- ingslide 13 adapted when the lock mechanism case I3 is linserted through the case 29 duringtheapplication of the mechanism to a door, to be moved to the'leftas shown in Fig.' l, so as to project into `the opening 26 (Fig. ll) and secure` thelock mechanism casing I3 to the knobmech-` V` anism casing-2,9., Asshown in Fig. 2, this'slide 13 projects throughan opening in the shoulder. 3| :so thatits projecting endis accessible forman ual engagement after the assemblyshown in Fig.- 2 has beenrinserted Iinto the openingv provided thereforf'in thendo'or and after the` casel I3 has been inserted into the bore IIv so that its. rear end-extends through the casing 29.` "It is believed' that from the foregoing it will be'clear as to the' assembly,of Athe parts sho-wn in Figj2, and that structure shownin this Vi'lgure is applied'to the dooras a unit before the application of the bolt mechanism in the case' I3 and lalso before the other sectionof the 'knob mechanism shown in- Fig. 7 and to bepresently described;Y It'may here be stated that afterL the assembly shown in Fig-2 is applied to thedoor `andthe bolt mechanismv casing I3 is lockedto the casing 29 by the lockawigsa..

ing.slide.:13,..the. inside..rose.14 may be threads.. ing'lyengaged. with-.the outer end. of the. casing v. 2-9.and, .after .it has been. screwed snugly. againstv theouter ffacingof .the-door, it willbe heldin placeby thedetent .66: as previously described in.. connection with. the outerrose 48.

The other portion of the knob mechanism com.- prising theY inner knoband certain partsasseme. bldtherewithis shown in Fig.. 1. This comprises.. a cylindrical knob shank 16 having mounted thereon. the inner `knob."I1.. Rigidly securedto the. sleeve 16 .by a pin..18 is the lockspindle, which spindlecomprises a square portion19;..a circular.. intermediate `portion 8),.a reducedcirui cularportionl, `and a flattened endportion 82.A Rotatably mounted on the rounded portion BI. of. this .spindle is a square spindle section .83,.de. signedtobetactuated by the outer knob ras .will be. herein described, this spindle section being. heldin. 4place by staking or displacing outwardly thel-.end-portion of the spindl-e section 8|.. as shownat .84.

Within the sleeve 16 is slidably mounted a tubular or sleeve-like plunger 851towhich is secureda ngerpiece 86, this sleeve being provided with.v a pair of L-shaped slots;81.which embracethe ends lofthe pin 18, -and is also provided. with a second pair of L-shaped slots 88 which..em. brace a sl-eeve 89 mounted in the member 16. Within .the sleeve 89. is a spring-pressed pin or detent 98-` urged outwardlyby thespring9l, the purpose of which will be described hereinafter.. Mounted within the sleeve or plunger 85 is a spring 92 which. acts against the ngerpiece 86:. at one end and against the sleeve 89 at the other en'dtonormally holdthe member 85 in its .outer position to urge it toward the .right as shown in Figs. 7 and 9. It will be apparent, however, that the-member 85, may be pressed inwardly by the member 86, this movement being permitted by. the slots Bland 88, which movementwill cause the end of the sleeve 85 to project beyond the. 'end of the sleeve 15 as shown inFig. 9. If the vfingerpiece 86 is rotated at this time, this rotation will cause the transverse portion of the slot.81.to engage the pins 18 and hold the sleeve 85 in the position shown in Fig. 9 against the action of the spring 92. When thesleeve. 85 is moved from the position shown in Fig. 7 tothat. shown in Fig. 9, it will through its engagement Withthe anti-friction roller 18 move the actuator 61 -of thedogging member to the left as the parts are shown in Fig. 1, and thus eiectthe. dogging of the outside knob through the pin 2l. Upon rotation of the member 88 in the reverse direction, the longitudinal portions of the slotsl 81 `,and 88,.wili then register with the pin 18 and. the sleeve 89, and cause the spring 92 ,tomove the sleeve 85` to its .original or inoperativeposition, i. e., the position shown in Fig. 7.

It will be. understood that after the bolt mechanism casing I3 .and the knob mechanism casing 29 with the assembled parts shown in Fig. 2 have been inserted in the door and locked .together by means-of the locking slide. 13, the inside knob assembly shown in Fig. 7 may then be inserted in place, the sleeve 18being inserted into the sleeve 51; The projecting end of the lock pin. 98 will `be depressed tolie flush with the outside ofthe sleeve 16 to permit this movement after` which the pin will Abe projected by its vspring to. engage in an opening 93 provided in the sleeve- 51 for this purpose. The portion 38 of the, casingv 29;v may beprovided with a small opening 94.fregistering .with the opening 93 ,topermitthe and the-sleeve. 511s iprorded .With a shallow. groove 95.. to.. slidably receive v,this pin, so that .the .inserr` tionof, ,the .sleeve .16. intov thel sleeve .,51. can. .beg effected in` one.positiononly. This will insure` thel,.regis.tration of the `pin 9Ilwith .the opening4 93..'so -that. it will. spring into place when. it arrives f opposite .thisopeningtosecurethe inner knobs to. thecasng 29@ l It .will 1ikewise.be..seen.from Figs...1 and 7 that` thesquarel portion .19 .of Athe main spindle,.en.

gagesthe innerrollback hubv I5, .while .the outer.. rollback hubis engaged by the squarespindle secs.`

tion-83; l.which is rotatablymounted with respect to.the`seetion .19. Likewise the llat end 82, of thel main spindle .projects through. the slot .45 .f in thev cap .44, .and it will. ber understood that this cap is..provided with .a lost-motion connection. with.. .thel key. barrel.. to. permit a certain amount. of..r0tation ofthe cap.` independently of. thekey barrel,.-so. .thattheinner knob may be rotated,

. v although the key, barrelwillbe held stationary.

From the above construction it will be apparent thateither knob may be rotatedindependentl-yzof the. other, the inner-knob 11l operatingv the bolt` bymeansof the square section 19 ofthe spindle andthe inner rollback hub. I6. The r outerknob operates the bolt. by means of the .square lsection 83..`of,the spindle, one end of which lits the Vhub I1 wh'ile .theother end is non-rotatablymountf. ed inf the ,opening 380i the outer knobshank.`

. Due .tothe rotatable mounting of the section v83.-

on the ,roundportion 8|.;.of the main spindle, the latter remains yatrest when the outer knob is roe.- tated;

It Ywill alsobe apparent that when the. sleeve 85.*.has been pushed inwardly by the ngerpiece 86andthe inner end vof this sleeve-has moved thev clogging member 22` by means of the actuatingA slide 61.1 so Kas toy dogthe outer hub I1 against movement, the .outer knob may not be. actuated. The innerknob can, .of course, be actuated in thev usual manner. and ,may also be` actuated from .the outside-of the. door by means vof the lock AI. Whenthe keyplug 42. of this lock is moved by, the. key ,in the usualmanner, the spindle 'I9 will be rotated dueto the connection of th'e iiatend 82..-.of vthis member .with the key barrel Which,. throughthe. pin 18,. will rotate the, inner knob and, therefore, actuate the bolt.

It will alsobe. apparent that when th'e partsl g, are assembledas shown in Fig. 1 of the drawings.

` and the locking slide 13 is moved inwardli7 to lock the-case` I3. to, the. case 29, the sections of the lock 'fwillybe rigidlysecured together .in proper. alignmentsov that there will be no binding or undue friction.between the. operating parts-of the structure. As the. boltmechanism casing I3. extends entirelythroughthe case 29 of the knob mechanism, it will eifectuallybe .held in place at its proper. angle ,regardless of-any misalign-V ment voi.the...openings.formed in the door. That. is,al1-that is required-isthat the openings be. sufliciently large to receive the parts disposed. therein, andthe casings will be positioned relatively. to each other by their telescoping engage-y ment without regard to the walls of th'e openings inlthedoor.

While l. haveshown anddescribed a preferredv embodimentof my invention, it willbe understood that it .is nottoA be limited to all ofthe. details shown, but-,is .capable Lof modification .and varias.
