Figure 9 is a view similar'to Figure 7 but with the lock yparts disclosed ina different The present embodiment of the invention is incorporated in a lock 11 disposed in a suitable cavity 12 provided in the free edge portion 13 of a door 14, and which isarvranged to be operated from the inner and out-er sides of the doorby means of knobs 15 and 16. kThe boltsy 17 of the lock isarranged to normally extend fromthe outer endof a Vbolt casing 18 mounted in the. door edge '18, such casing ,being laterally Vflanged adjacent the point of emergence of the bolt therefrom whereby it may be mounted in fixed relation in and to the door edge,A it being noted' that the casing flange is also arranged to conceal the mouth of the portion of the cavity y12 which extends-to the door edge.

Slidably mounted in the casing 18 isa bolt yoke or latch plate member 19v for actuating ythe bolt 17, such member being here shown hollow and of generallyrectangularoutline and being urged to assume and maintain an outer position by reason of a spring21 operatively engaged behind it. The forward end ofthe latch plate 19 is perforated as at 22 'for the slidingreception olfa shank 23 ex'- tending inwardly from the bolt, such -shank beingsp'rovided at its inner extremity with.

an enlarged head 24 which is arranged to limit the outward movement of the bolt shank through the opening 22. A compression spring 26-is disposed about the shank 23 and between the inner end of the bolt head and the outer end of the latch plate 19 whereby the'bolt is arranged to be normally held extended from the latch plate for retraction therewith, 'and at the same time may be retracted independently of the latch plate. Journalled in the casing 18 to extend horizontally therethrough is a latch actuator 27 having extending therefrom intermediate the casing walls an arm 28 arranged for engagerment with the latch plate 19in suchA manner that a rotation of the actuator fromthe nor-Y mal position shown in Figure-will effecta retractive displacementof the'latch plate. Preferably, and as shown, the actuator arm 28 is arranged for engagement with the latch plate bothat the upper and lower sides thereof whereby a rotation of the actuator in either possible direction may lretract the latch plate. s y Y The. casing 18, itis noted, is formed with Y generally like and transversely separable sec tions V29 and 3,1, the plane of separation of thevsections extending longitudinally ofthe casing and perpendicular to the vaxis of rotation of the actuator 27 Ends 32 and 33 of the casing sections are extended for an overlapping relation, and flat flanges 37 and 38 at the other ends of the respective sections are:y arranged to lie in coplanar relation whereby they may be simultaneously en- 'f--gaged in opposedgrooves 39 provided at the ybackijof an edge plate 41.` The plate 41 is perforated to permit theprotrusion of the bolt therethrough, it being noted that 'the `bolt must be pushed back `beyond the plane ofthe plate 41 during theinstallation orremoval .off the plate. The plate`41 is also per- Vthe spindle slidably engages the perforation esv 43.` As shown,-. the perforation and spindle are of like polygonal section for effecting an operative engagement thereof. The ends of the spindle 44 extend from both sidesof the actuator, and arel arranged tobe connected to the knobs land 16 whereby they may be ,operatedwthereby rIvhe spindle 44 is arranged to carrv'the knobl infixed relation thereto vat all times. VAs'shown,'the spindle end portion 46arranged for engagement with the knob 15 is threaded andV has-threadedly and adjustably engaged thereon a member 47 providing a conically tapered friction face 48 for engagement in a-complementary vhead bearing against the knob at the outer end of its perforation 53. In this manner, .with the member 47, set as required, the screw 52J may be tightened against the knob to 1 clampA the knob Vbetween its head and the member 47. l Y t The knob 16, it will benoted, vcarries a key controlled tumbler barrelg54 axially joui nalledV therein, theinner end of the barrel being provided with a recess into which theY inner key end protrudes when the key is fully engaged in the barrel, the latter relation being indicated in Figure 4. The sleeve portion 56 ofthe knob 16 is removably secured'to the knob portion proper which carries the tumbler barrel, by means of screws 57 engagedvthrough a radial flan-ge at the outer end of the sleeve, said fiange and the opposed knob surface preferably being provided with interlocking portions for preventing a relative' rotation of the sleeve and knob independently of the screws 57.

Means are provided whereby the knob 16 and spindle-44 may be locked together against relative rotation or released from such locked engagement by ,appropriate manipulations Kof the inner knob 15. As shown, the bore of the sleeve 56 is formed with three distinct portions 58, 59eand 61 of differing diameters. The .bore-portion 58 is of circular section and has thesmallest diameter ofy the three bore portions,.the diameter thereof being, however, 'larger than the; spindle portion engaged therethrough. Slidably mounted on. the spindle is a spool-shaped member 62 having one end iange 63 disposed inwardly of the innerend ofthe sleeve yand the other end .flange 64 engaging in the intermediate bore portion 59. A compression spring 65 is mounted on the member 62 in encircling relation thereto, with one end of the spring engaging the iiange 64 while the other end engages a shoulder 66 on the inner end of the sleeve56. While slidable on the spindle, the member 62 is arranged for rotation therewith, .such being here shown effected by forming the bore of the member and the spindle portion engaged thereby of polygonal section. In this manner, the member 62 is arranged for rotation with the spindle at all times.

Extending from the inner end of the sleeve face 56 ,is a tapered projection 68, said projection being arranged for engagement in a Vspindle permits an adjustable mounting the knob axially along the spindle,

radial notch 69 provided' in the opposed flange 63 of the member`62. .The engage- -ment of the proj ection 68 in the notch 69, it

will be noted, locks the sleeve 56 to the member 62 for rotation therewith and with the spindle, it being further noted that the spring 65 is constant-ly operative to urge such engagement between the sleeve and member. Threadedly engaging the spindle outwardly of and against the'inember 62 is a nut 71, said nut being longitudinally slidablek and nonrotatably engaged in the sleeve bore portion 59. Preferably, and as shown, the nut 71 is hexagonal and the bore .portion'engageable thereby is of like section whereby rotation of the nut in andv with respect to the sleeve is prevented. It' will now be clear that if the spindle be axially displaced to release the projection 68 from the notch 69 against the resistance of the spring 65, a relative rotation of the knob 16 and spindle 44 is permitted. And it will be further noted that the threaded engagement of the nut 71 with th;

Mounted on the spindle 44 outwardly of the nut 71 and in the outer bore portion 61 is a sleeve 72. The sleeve 72 slidably and non-rotatably engages thespindle, the spindle and sleeve bore being of polygonal` section for this purpose, it now being noted that the entire spindle portion engageable within the knob sleeve is conveniently of the same section, since the member A62 is similarly engaged with the spindle Vat the inner end of said sleeve. The outer end of the sleeve 72 extends into the tubular barrel recess 55 and is diametrically slotted to receive the tip of a proper key 7 3. With the'knob 16 relatively fixed, the insertion of the keyreleases the tumbler barrel for rotation in the knob and the spindle is turnable directly by the key, providing, of course, that the knob sleeve is not locked to the spindleby the member 62, which condition obtains when the spindle is disposed to free the projection 68 from the notch 69. In this manner, the spindle is arranged for a direct key operation thereof when the knob is inoperativewith respect thereto. It is noted that the sleeve 72 is freel.v1 rotatable in the bore portion 61 and is held against axial displacement therein by reason of its engagement between the tumblerbarrel and the shoulder 74 defining the inner end of said bore portion. s n

Means are provided for holding the outer knob 16 in lixed relation to the door andthe belt casing 18, said means being hereinafter described. With the knob and its sleeve 56 thus held against movement, the spindler 44 pull on the inner door knob 15. Since such `same time permits the use of a key for opening the door from the outside thereof wherebythe lock then constitutes a key lock, means are provided whereby the spindle may be held set in said position against the resistance of the spring 65. Accordingly, and as shown, a plate 75 is mounted on the spindle 44 between the bolt casing 18 and the outer knob sleeve 56, said plate beingswivelled on the spindle for axial displacement therewith. In the present embodiment, the plate 75 is provided witha radial notch 76 extending from its center and having the plate edge portions at its inner end engageable in'an annular groove 77 provided in thel spindle. vExtending axially from opposite sides of the plate 75 toward the lfnob sleeve 56 are extensions 78, said extensions being arranged for sliding engagement in a pair of cooperating slots 79 providedin the cylindrical surface of the sleeve. `When the plate extensions 78 are engagedjin the slots 79, the plate 75 lis arranged 'to vbe held against lateral removal from its swivelled engagementv with the spindie. it being also noted that such engagement of the extensions in the slots locks the platel against relative rotation with respectl to the sleeve. The extensions 78 are of such length that they maintain their engagement in the slots kboth when the spindle is moved inwardly to effect a release of lthe 'knob 16 therefrom and for different adjusted distances between Y the knob sleeve andthe bolt casing.

Extending laterally from latch plate 19 through slots 81 provided in the bolt casing 18 and toward the plate 75 is an extension 82, said extension being provided with an opening 83 adjacent its outer extremity for the reception of a radial extension or detent 84 provided on the plate 75. The free edge of the latch plate extension 82 is bevelled and this extension is so related to the plate extension 84 that when the latter is moved inwardly, it forces back the former against the resist'- ance of the latch plate' spring 21 until the detent 84 enters the opening 83. In this mannen a simple detent means is provided for holdingr the spindle in its inner position. It is noted that when the detent 82 is engaged in the opening 83. a rotation of the plate 75, and so of the knob 16,- is prevented, thereby both holding the knob fixed during the actuation of the key therein and indicating that the door is locked. Preferabl i and as showny n u a 7 pairs of oppositely related extensions 82 and `84 are provided on the latch plate 19 and plate respectively whereby the positions of the knobs may be reversed with respect to the bolt casing. It is noted that the relation ofthe parts when the spindle is' set iny its inner position is shown inVFigure 9, while Figures11,x4, 5 vand '7 disclose thelock parts .as related .when the outer Vknob 16 is operable for actuating the spindle. Y

Release of the spindle to return to its outer position is .effected Whenever the spindleti's rotated to displace the latch plate for disengaging the extension opening SSfrom the detent 84. In this manner, a rotation ofthe spindle from either side-of the-door restores the spindle `to its outerposition and renders the lock operable bymeans of kthe outside knob, it being clear that the'lock is always operable'by means ofthe inner knob. This feature as to the ldisposal of the spindle is particularly valuable when the lock is used on inside doors, sincethe lock mustl be deliberately set for key Voperation following each opening actuation thereof.

' An escutcheon plate 85 for engagement against the outer door surface is mounted on the sleeve 5G of the outer knob 16. As shown, the plate 85 is of circular outline and is provided with a circular opening 86 for the reception of the sleeve v56; vThe sleeve 5G, it is noted, is provided with an annular groove 8T adjacent its inner end, said groove extending substantially to the bottom of` the slots 79.

.Projections 8S entend inwardly from the edge of the escutcheon opening 86 for engagement in the groove 87, said projections being placed Vin said groove by advancing them `through the slots 7 9 as far as the groove and then rotating the escntcheon plate to agreater or less degree about the sleeve. The escutcheon plate, it is noted, extends outwardly along the sleeve and cooperates with the knob to hold an annular shell 89 in place, said shell completing the concealment of the sleeve.

.Extending axially inward-ly from the escutcheon plate 85, is a cylindrical shell 91, said shell being cutaway at opposite sides to receive the bolt casing 18 transversely therethrough, preferably in litt-ed relation. Seg mental webs92 are provided across the inner ends of the portions of the shell 91, said .webs beingprovided with threaded perforations 93.- AA plate 94 is provided for disposal against the inner door side, said plate being perforated for Vthe' freel reception of the spindle 44 therethrough. Screws 95 extend through the plate 94 for engagementrin the perforations 93 of the webs 92 whereby the door is arranged to be clamped between said vplateand the escutcheon plate 85. The nut 47, it is noted, is preferably arranged to be disposed closely adjacent the plate 94 when the spindle is in itsv outer position, andas here shown said nut is provided with an exftension for fitted engagement inthe plate perforation at the spindle whereby the plate may be properly set before the screws 95 are tightened.

It will now be clear that with the lock of Vmy invention installed on a door and having 'the knob spindle `inits outer position, a per- -son'mayactuate the lock for opening the door by means of either knob. If,`however, the

person wishes to prevent the opening of the door from the outside, itis merely necessary ing 83 of the llatch'plate extension 82. The

use of a vrkey in the tumbler barrcl54 is then required for opening the door froin'the outside. By vand upon the useof a key, or the opening'of thedoorv by means of the inner knob, the spindle and inner knob are freed to assume their outer position whereby the outer knob isautomatically restored to its operativeness.` The adjustable mounting of the knobs onthe. spindle and the Vreversibility of the operative parts` for alternately connecting the .outer knob with the latch plate and spindleV makesv possible the use of a single model of the lock on doors of different thickness and doors hung in various relations to their openings, whereby the lock is arranged for universal application without alteration.
