17 vClaims.

vThe invention relatesv to door looks of the spindle-operated latch-bolti type and more particularly to the class especially designed for use with doors in dwellings.` e

An object of -the invention' is to .provide a lock of the type described whichflmay be so positioned that retraction of the latch bolt without the use of a key from the outer side of thev door, cannot be eifected by Operating the lock froml the inside of the door invany: manner.

Anotherobject of the invention is to provide i in connection with a spindle operated latch an emergencylock which may` be operated from the inner side of the door for-permitting or preventing the retraction of the latch bolt from the outer sideof the door, but may be key operated fromA the outer side of the door to render all other latch `retracting means on the. door inoperative. w

A` further object of the invention is to provideV a lock of the character'described-in which, i

in addition to the regular key operated lock for controlling the operation of the spindle from the outer side of the door, there is provided a key operated emergency llock which may be used to prevent operation` of the regular lock with the key or otherwise. i

An additional object of the invention is to provide a lock of the Character described which is so secured in position on the door that it ,cannotV be dismantled from either side of `the door when the door is in closed position.

A still furtherobject is to providea lock` of the .Character described in which the various parts thereof are of extremely simpleconstruction andv designed to permit ready conversion of the lock from one type to another with little or no substitution of the parts.

Yet another object is to provide for the lock 40. an escutcheon for the inner side of theidoor which may be held against the door without the use of screws or other visible means.

Yet a further object of the invention is to provide a lock of such design that the inner extremity of the latch housing may `terminate within the` cylindrical bore `through which the spindle extends so that a minimum amount of drilling will be required and .the necessity) of gauging the depth of the bore for the housingv Will be eliminated. i

The invention possesses otherv vobjects and features of advantagefsomeof which,` with the foregoing, will be set forth in the following de- 5 scription of the .preferred form of, the invention 5 which'is illustrated in the drawings accompanying and forming part of the specification. vIt i is to be understood, however, that variations in the showing made by .the said drawings anddescription maybe adopted within the scope of the invention as set forth in the claims. Referring to said drawings: Figure 1 is a Vertical sectional view of a lock embodying the features of my invention ,and operatively positioned on a door. 7

Figure 2 is a fragmentary view 4similar to Figure 1, but showing the spindle of thello'ck What is herein referred to as the retracted position. v

Figure 3 ist a detail view of the. different parts of the lock as illustrated in Figure 1 and showing the parts disassembled but substantia1lyin'- the order of their assembly, some of the parts being in elevation while others are .shown either in section or perspective. i

Figure 4 is a Vertical transverse section of the lock taken on the line 4-4 of Figure 1. Figure 5 is ahorizontal sectional view of the lock as shown in Figure 1, the plane of the section being indicated by the line 5-5 of the latter figure. Figure 6 is a Vertical sectional view of the lock Vtaken at right angles to Figure 1 on the line 6-.6 and illustrating particularly the Vemergency locking members. i

Figures '7` and 8 are detail sectional views showing the different positions of some of the emergency lock members. i Figure` 9 is a Vertical sectional view of the lock similar to Figure 1 but showing the lock With a` spindle not permitting longitudinal displacement.

Figure 10 is a view similar to Figure 9 `but showing a still further modified form of the lock.

'I'he features of my invention are in general of such nature as to render them applicable to latch bolt looks both of the type having a longitudinally-displaceable, spindle and the type inwhich the spindle is permitted only a rotative motion for effecting the retraction of the latcrh. Accordingly in the drawings there are illustrated examples of each of these types of looks, to wit in Figures 1 to 8 inclusive is depicted a door lock inwhich the spindle may be moved longitudinally as well as rotatively in efiecting the various looking or releasing movements, while in the remaining figures the lock is shown provided with a spindle permitting vonly rotatable motion -for efecting such movements;

For the sake of convenience and simplicitye in the mass productionof the locks, as well `'as` for permitting ready conversion from Vone form .of

i bore 17 of the door. .inner side 18 of the door is a plate 19 which is lock to another, the spindle assembly particularly applicable for use in the looks where the longitudinal movement is permitted, is also utilized in the lock such as in Figures 9 and 10 where only the rotation of the spindle is required, means being added or substituted in the latter case to render the longitudinal displacement of the spindle impossible or at least of no effect. It will thus be understood while the spindle construction and assembly in the last mentioned figures is substantially the same as in the lock illustrated in Figures 1 to 8, such duplication is not essential.

As shown in Figures 1 to 8, the lock of m invention comprises an inner casing 12 having a side plate 13 which is arranged as here shown to set against the outer side 14 of the door on which the lock is mounted. The casing is also provided with segmental substantially quarter round shell sections 16 which are fixed to the plate and are designed to fit in the cylindrical Designed to set against the secured to the sections by means of screws 20 and thereby clamps the casing in the' door, the screws as will be seen being insertible and accessible from the inner side of the door only. Arranged centrally within the, sections and extending through the plates 13 Vand 19 is a spindle 23. on the opposite extremities of which are mounted or operativelyl connected

knobs

22 and 23, the knobs'being in the order mentioned respectively disposed at the outer and inner sides of the door. The plates are concealed by

escutcheons

24 and 25 which as here shown are respectivelyl associated with' rosette portions 26 and 26' which enclose'the portion of the spindle'betweenthe side of the door and the inner ends of the knobs, the rosette 26 being inteflrally combined with escutcheon 24 while the rosette 26' is formed separate of and arranged to rotate relative to escutcheon 25. The escutcheons are secured in position byV means of screws 27 which are inserted through the outside escutcheon 24 and designed to engage in internally threaded hollow studs 28 which are preferably fixed to and extend inward- 1y from the inside escutcheon 25 and closed at or by the latter so as to prevent access to the screws 27. It will be noted that since the screws 27 are accessible only from the outer side of the above, and the screws 20 accessible only from the inner side, dismantling V'of the' lock cannot be effected when the door is in closed position.

The spindle is designed to actuate a latch-bolt 29 which is designed to normally protrude from the outer end of a bolt-latch housing 31 extend-v ing perpendicularly to the spindle and removably fitting at'i'its inner portion between the Sections 16.; The housingl as will be seen from Figure 5 is disposed in a bore 32 formed in the door and lying perpendicularly to the bore 17, and it is important to note that the inner extremity of-the latch housing does not protrude from the casing, and in this manner drilling of Vthe bore 32'for the accommodation of the latch -housing need onlyV be effected from the edge of thedoor to the bore 17. Operation of the latch bolt by the spindle is through the medium of Van actuator 33 which is rotatable with the spindle and is arranged to engage a latch plate 34 slidably disposed in the housingand connected to the bolt; A spring '35 in the housing urges the plate to anv outwardly extended position while a spring 36 Vperforms a similar function in normally holding the bolt extended from the housing.

The inner knob 23vis directly secured to the spindle so that it will rotate and move axially with the spindle as a fixed part thereof. As here shown the knob is secured adjustably on the spindle by means of a screw 23' which extends from and through the forward end Vof the knob and engages in threaded inner knob member 23" and an internally threaded bore of the spindle.

The outer knob in the embodiment of the invention now being described is arranged, according to whether the spindle is operatively connected with or disconnected from the knob, to effect rotation of the spindle or be inoapable of effecting such rotation, to bring about the release of the latch. Operative connection or disconnection between the outer knob and spindle is preferably arranged to be effected by moving the spindle longitudinally to one position or another, the connection between the two being effected as here shown when the spindle is retracted and disconnected when returned to an outwardly extended'poeition. The outer knob is designed in this enibodiment to be supported for rotative movement but against longitudinal displacement and as will be clear from Figure i, has fixedly secured thereto a hollow shani: 37 which extends through the plate 13 and surrounds the spindle portion thereat. The shank is formed with a polygonal opening 38 in which is arranged to engage in the retracted position of the spindle aV correspondingly shaped portion 21' of the spindle so that rotation of the latter may be effected by the knob. Since as aforesaid the longitudinal displacement of the spindle is designed to effect-a disconnection of the outer knob from the spindle, a reduced portion 39 is formed on the spindle, which when the spindle is in the extended position, that is moved toward the outer side of the door, the sides of opening 38 will be operatively released from the spindle 'whereby relative rotation between the spindle and outer knob is permitted. Retention of the spindle in avnornially outward position, that is with the' reduced portion 39 engaging in the 'opening 38, is eifeoted by means of a spring 41 interposed between a part of the knob shank and a fiange 42 formed on a transversely separable shell 43 which surrounds the extremity of the spindle and is secured thereto against relative axial displacement. Anchoring of the shanlr in theV plate 13 is preferably acccmplishedby fitting the reduced end 44 of the shank in the plate opening and securing the same therein by means of a disk 46' which has a bayonet connection with the shank portion 44 and is arranged to bear against the inner face of the plate. The shank is held against moving in- Vwardly through the plate by a ring 47 which is -the knob to the casing when the spindle is eX- 1.1

tended. Accordingly there is provided on the spindle a disk 49 held against longtudinal displacementrthereon by stop washers 51 and held againstirotation with the spindle by engagement of a protuberance 52 of the disk in the longi- 'tudinally extending' space between the casing segments 16; `the disk is formed with notches 53 in which is arranged to cngage, on the retraction of the spindle, a pair of dogs 54 held on 'the knob shank, the dogsbeing so designed that upon extension ofl the spindle, that is, when the outer knob and spindle are connected for rotation, they will be released from the disk. The dogs as will be clear from'the drawings extend through the plate 13 and disk'46. and are slidably mounted in longitudinally extending recesses 56 formed in the knob shank, the forward extremities of 'the dogs being engaged by the spring 41 so as to keep them in extended position and at the same time permit the temporary retraction of the dogs in assembling the bayonet disk on Vthe shank; For the' 'purpose of effecting the retraction of the spindle, there is provided in the rose 26' .which is mounted to rotate about a cylindrical extension 58 on the plate 19, a sleeve 59 which is slidably held in the rose but prevented from rotating relative thereto.

The sleeve is provided with projections 61 arranged to engage the cam faced extremity of the extension 58 whereby on rotation of the rose the inner knob which is pressed against the sleeve and fixed to the spindle will be moved outwardly. A double acting clock spring 60 preferably carried by the ring 47 and cooperating therewith and the plate 13 serves to resiliently urge the outer knob in such position as to enable the dogs to readily enter notches 53 on retraction of the spindle. vTo insure against loosenessin the engagement of the aforementioned parts, a spring 62 is interposed between the inner end of the knob and the wall 63 of the rose in which the sleeve is carried. Moreover, it will be noted that since the wall 63 is fixedly secured to the rose-Shell, the spring 62 Amay eifectively serve to hold the rose against the side 'of the door 01' the escutcheon, or as here shown against the clamping plate, without the use of screws. To facilitate the manual turning of the rose, a button 64 or the like may be afiixed thereto. It will now be clear that by a simple turn of the rose at the inner side of the door,V the use of the outer knob as a means of actuating the spindle is permitted or prevented as desired; i

When the spindle'is in position disconnected from the outer knob, the only manner by which the `spindle may be rotated from theouter side of the door, is through means including a key, and such means as here shown comprises a cylinder lock 67 fixedly mounted in the outer knob in axial alignment with the spindle and arranged to be operatively connected with the spindle by means `of a key 68. The latter is insertable in the lock through the front face thereof andV when operatively disposed Vin the lock, .projects from the rear thereof whereby the free extremity of the key may engage in one of the notches 69 formed in a spindle connector 71. The con'- nector is held for rotation in and against axial displacement to the outer knob but the spindle has a slip joint attachment with the connector so that the latter may be operatively connected with the spindle to effect rotation thereof in each and every of the possible positions assuniable by the spindle in the different Vforms of the lock. It will be understood, of course, that while the spindle is directly operable by the key, only the proper key may be inserted through the lock for permitting such operation. An important advantage of requiring the use of the key for turning'the spindle is that should the cylinder' lock be picked to permit rotation of the cylinder, such rotation would in no manner effect the rotation of the spindle.

Means are provided on the lock, which is operableiunder certain conditions from each side of thedoor, for preventing the rotation of the spindle from the outer side of thevdoor in any manner,V or in other words for preventing the operation of the spindle by the key or by the outer knob regardless of the longitudinal position of the spindle. In the present form of the invention, said means in addition to preventing the operation of the spindle from the outer side, also acts to hold the inner knob from rotating the spindle. The means is in the nature of what may conveniently be Vtermed an emergency lock and is incorporated in all of the forms of the invention here illustrated. In general,A such means comprises a spindle looking or releasing means which may be operated from the outer side of the door by a special key that is different from the first mentioned, and may be operable from the inner side of the door without a key. As clearly shown in Figure 1, said means in detail comprises a lever 72 fulcruined to the plate 19 preferablylbelow the spindle and movable to and from a spindle holding or spindle releasing position. Engagement between the lever -and spindle is here shown arranged to be effected through means of a crank '73 which while permitting axial displacement of therspindle therein, is held thereon for rotation therewith. The Crank, as clearly shown in Figure 6, is provided withan arm 74 which is arranged in the different positions of the lever as aforesaid to engage in or se removed from a recess 76 formed in the lever, the spindle as will be readily understood being held against rotation when the arm is engaged whereas release of the spindle will be effected on disengagement of the arm. Movement of the lever from one position to the'other is arranged to be eifected by a yoke 74 fixed on a shaft 76 which is preferablysupported for rotation in one of the 'escutchecns and in parallel relation to the spindle. The yoke 74 engages the lower of the lever and on oscillation of the shaft causes the lever to move from one position to the other. Normal retention of the lever in each of its positions is effected by a spring pressed pawl 77 which bears against the lever in spindle engaging position so as to vretain the crank arm seated in therecess, while in spindle releasing position it ssats in a depression 78 to resiliently hold the lever againt movement. Oscillation of the lever` from the inner side of the door is permitted by means of a thumb knob 79 which is fiXed'ito the shaft. Ai'ranged in concentricrelation to the shaft and mounted for rotation in a Shell 81 provided at the rear sideof the outer escutcheon, is a lock cylinder 82 which may be rotated by means of a key 83 insertible from the outer side of the door; The cylinder vis fixedly secured toan arm 84 which on rotationof the cylinder in one direction or the other engages a Crank 86 on the shaft to oscillate the latter in the same inanner as-by the thumb knob 79. For the purpose of looking the `cylinder in position preventing the operation of the spindle, or in position permitting such operation,

slots

87 and 88 are formed in the shell into which the tumblers from the look are extended when the cylinder is moved to said positions, it being understood that retraotion of the tumblers topermit rotation of the cylinder can only be effected by means of the key 83. By referringv to Figures 7 and 8, it will be seen that when the cylinder has been positioned to allow rotation of the spindle the cylinder arrn 84 is so disposed that loscillation of the shaft by the thumb knob to move the level' to one position or another will not be interfered with by either the'crank or said arm. On the other hand when the cylinder is locked in spindle holding position, the cylinder arm will beV engaged by the crank to thereby prevent any movement of the V'shaft. In this manner as will now be clear, when the emergency locking device is key locked in what may conveniently be called the open position, the spindle may be readilylocked or released from the inside of the door whereby operation of the spindle from the outer side of the door by key 68 may be prevented or permitted, and reversely when the device is key locked in the other or closed position, no operation of the spindle can in any manner be eifected from the outer side of the door andl for that matter not even from the inner side of the door. It should be understood that the key 83 or the knob 79 in releasing the emergency lock does not act in any manner to operate the spindle, and therefore operation of the spindle from the outer side of the door will still require the use of outer knob key 68. Thus for example where the lock is used in a hotel for the door between a guest room and a corridor, the emergency lock key is kept by say the hotel manager while the knob key is placed in possession of the guest. In this way when the room is turned over to the guest, the manager locks the emergency device in open position and retains` the key 83, and gives key 68 to the guest. It will thus be seen that the guest retains the usual degree of privacy, since the manager is to use` the key 83 only in the case of einergency and access to the room is afforded to -the hotel employees with a duplicate of key 68. At the same time the guest may protest himself against intrusion by any employee or other person having a duplicate of key 68 by positioning the thumb knob to prevent operation of the spindle. But no operation of the lock by the guest may prevent the manager, in case ofnecessity, from gaining access to the room, since the latter may always'through medium of key 83 rotate the shaft and thereby release the spindle for actuation by key 68.

In the modified form of the lock illustrated in Figure 9, the outer'rknob is designed to be held against rotation at all times, and therefore the longitudinal displacement of the spindle is not'utilized as a means of Operating the lock. In order however thatthe same parts be utilized in this lock as in the first described lock, means are provided for preventng said longitudinal displacement so that the spindle cannot be manipulated in this manner either purposely or accidentally. Such means, as here shown, is in the simple form of' a washer 85 removablycarried on the spindle in a' grooveBG therein and arranged to bear against an inner wall 91 of the outer knob, the Washer being held against said wall while the dogs are fully Vprojected in the disk 49, thereby positively holding the spindle against `any longitudinal displacement'and preventing any rotation of the outer knob. Preferably since the turning rose is not required in this embodiment, an escutcheon 88" is substituted for the escutcheon and rose used in the previous embodiment. As will now be clear, the feature of this lock as compared with the other is that operation of the spindle from theV outer side of the door cannot under any circumstances be effected without the use of a key 68, thus at no time will there be any possibility of the door being opened from the outer side by turning the knob. Under some conditionsthis lock is quite desirable, While under others the first type is preferable, and since practically all parts in both types of looks are the same, conversion of the lock from one type to'the other; in accordance with the conditions of use, may be effected with little or no expense. Z

A further modified form of the lock is illustrated in Figure 10. `In this embodiment the key lock for the outer knob is dispensed With, and in lieu thereof said knob is directly connected to thevspindle in substantially the same manner as the inner knob. With this form of construction operation of the spindle is effected entirely by the inner and outer, door knobs, the emergency lock serving to control the actuation of the spindle the same as in the embodiment of Figures 1 to 3. This form of the invention is particularly applicable for doors connecting independent rooms to a bathV room. In such installation the thumb knob is retained on the bathroom side of the 'door so that the occupant may lock himself in the room against intrusion. By the use of the key a door may be locked so that operation of thespindle from both sides of the door is prevented, such feature being desirable also in hotels Where in some instances it may be necessary to have the bath room aoeessible from but one of the connected rooms. An extremely important advantage in the use of this lock in bath rooms is that 'permits the release of the spindle from the outer side of the door by the key 83 in the event the occupant on the inner side has locked himself in and is unable to operate the thumb knob. This situation of looking the occupant in the room is quite apt to cccur in the case of a child or a person becoming ill or unconscious while in the room. With most looks, as heretofore constructed, access could not have been obtained to the room except by a window or by mutilating the door and lock. With my lock, it is only necessary in such condition to procure the emergency key and rotate the cylinder to release the lever. This releasing feature is common to all of the locks herein described, and is afforded without the use of the mechanical complications usually prevalent in lock installations having such a feature.
