LOCK.

Specification of Letters Patent.

Patented d1 une 22, 1915..

To all whom it may concern Be it known that I, SELBY G. CARR, a citizen of the United States, residing at Muskogee, in the county of Muskogee and State of Oklahoma, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to looks and has as one of its objects to provide a look so constructed that itvwill be unnecessary to use a key in order to adjust the lock to secure the door to which it is applied.

Another object of the invention is to provide a lock which may be so adjusted that it can not be unlocked from without even by the use of a duplicate key.

' The invention has a further object the provision of a lock possessing the characteristics above mentioned, Which lock may,

without disarranging any of its elements, be

readily and quickly applied'to a door of any thickness within reasonable limits, the adjustment of the lock to a door of gi thickness being accomplished prior to the fitting of the lock to the door and without the necessity of repeated trial fittings and adjustments.

The invention also aims to provide a look so constructed that it may be readily adjusted so that it may be unlocked from with- A in or without, without the use of a key;

so that it may be unlocked from within without the use of a key, and from without by the use of a key; and, so that it may be unlocked from within but-cannot be unlocked from without even by the use of duplicate keys.

Another feature of the invention resides in a novel tumbler mechanism arranged for actuation by'the use of a proper key and, upon actuation, to adjust the lock mechanism so that rotation of the outer knob will serve to unlock the door.

Still further the invention aims to provide, in a look, a novel form of escutcheonplate so constructed that the door to which the lock is applied will expand and contract without the plate becoming loosened and without the lock mechanism being in any way affected.

Still further the invention contemplates the provision of a lock having all of the characteristics above mentioned, which look may without any considerable adjustment of parts he applied and attached to a door opening inwardly or outwardly.

For a full understanding of the inven- I tion reference is to be had to the following description and accompanying drawing, in

which Figure 1 is a vertical longitudinal sectional view through the lock, the parts there of being adjusted to permit of the door being opened from within or without by the verse sectional View on the line 4-4 of Fig.

1, the parts being illustrated in position to permit of the door beingopened from without by the use of a key. Fig. 5 is a view similar to Fig. 4 but illustrating the parts so arranged as to prevent the lock being manipulated even by the use of a duplicate key.

Fig. 16 is a perspective view of a dust-guard shell which constitutes an element of the tumbler mechanism illustrated in Figs. 13, 14 and 15. Fig. 17 is a vertical transverse sectional view on the line 1717 of Fig. 1 looking in the direction indicated by the arrows.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

In the drawings the inside escutcheon plate. is indicated by the numeral 1 and the outside escutcheon plate by the numeral 2.

By referring to Figs. 1, 2 and 3 of the drawings it will be observed that each of the I plates is relatively thin and that each is provided at its periphery with a relatively narrow flange 3, the edges of these flanges resting against the faces of the door against which the plates are secured. As before stated, the lock embodying the present in vention is adapted for application to doors of various thicknesses and to this end means are provided for adjustably connecting the two escutcheon plates. The plate 2 is formed upon its inner-side or face with two or more interiorly threaded sleeves 4, and screws 5 are fitted through openings in the plate 1 and are adjustably threaded into the said sleeves, the door which is indicated in the drawings by the reference character D being formed with openings 6 receiving the said sleeves 4 and screws 5. At this point it is to be noted that inasmuch as the edges of the flanges 3 bear against the opposite faces of the door D, the door may swell or contract without the plates becoming loosened. Furthermore, it will be noted that inasmuch as the sleeves 4 are formed upon the inner face of the escutcheon plate 2, the plate iswithout visible means of attachment to the door and'consequently, cannot be readily removed by one endeavoring to disturb the lock-mechanism.

The door D is formed with a mortise 7 and with an opening 8- which extends therethrough andis in communication with'the mortise. Th e escutcheon-plates 1 and 2 are formed respectively, with openings 9 and 10 which register with the opening 8 when the escutcheon plates arev properly positioned upon the door. The outer faces of the escutcheon plates 1 and 2 are formed respectively with flanges 11 and 12 which surround the openings 9 and 10, although of greater diameter than the respective openings.

The inner and outer knobs ofthe door are indicated in general by the numerals 13 and .14, and the outer knob 14 consists of a section 15 and a cap-section'lfl which has its peripheral ortion overturned about the edge of the flare portion of the section 15 as indicated at 17. The said section 15 is reduced in diameter, as at 18, and is further reduced in diameter, as indicated at 19, and is formed upon its last mentioned reduced portion with a circumscribing rib 20. In reducing the section as at 19, a shoulder is formed which is spaced from the rib and the materialof the escutcheon plate 2 between the opening 10 and flange 12 is received between the said shoulder and the rib 20. The flange 12 projects into the reduced portion 19 of the knob section. At this point it willbe seen that the knob is connected for turning movementwith the escutcheon plate 2, but that it cannot be disconnected from the plate except by destroying either the plate or the knob.

The knob is provided with a tubular shank '21 which is formed with a slot 22 and this shank is open at both ends, its inner end 20 upon the shank of the knob section 15 and the material of the escutcheon plate which lies between the opening 9 and flange 11 is received between the shoulder formed by reducing the shank 25 as at 27, and the rib 29,

the flange 14 projecting into the reduced portion 28. At this point it will be observed that the shank of the outer knob slidably fits within the shank of the, inner knob but that due to the engagement of the rib 26 in the slot 22 these knobs are at all times held for turning movement in unison; however, the escutcheon-plates 1 and 2 may be adjusted toward or from each other without disturbing this connection.

The casing for the bolt of the lock is indicated in general by the reference numeral 30 and .is carried by an attaching plate 31 formed with the. usual opening 32 for the passage of the head of the bolt. As shown in Figs. 1, 2 and 3 of the drawings, the casing 30 is formed in opposite side walls with openings 33 in which are mounted the ends of a rocker 34 which consists of a hub provided with oppositely extending shoulders 35 arranged to coiiperate with lugs 36 at the ends of the arms of a yoke 37 located at one end of the latch-bolt. The lock and latch bolt is indicated in the drawings by the numeral 38 and the head thereof is indicated at 39 and has a rounded nose 39" as distinguished from the nose of the ordinary latch-bolt head, which is flat. The shank of the bolt 38 is formed with a slot 40 in one end of which is normally engaged the usual tubular post 41 which is integral with one side-wall of the casing which receives the usual screw 42 which serves to hold the opposite side-wall of the casing in place. A spring 43 is arranged within the slot in the shank of the bolt and bears at' one end against the post 41 and at itsthat upon rotation of the rocker 34 in one Y direction or the othcr, the bolt will be retracted owing to the engagement of the shoulders 35 against the lugs 36, against the tension of the spring 43 so as tomove its head into the casing and outof locked position. For a purpose to be presently explained, therocker is formed .in each end with a plurality-of diametrically oppositely located notches 44 and the notches at one end of the rocker alternate with the notches at the other end, or more specifically speakdrawings that the tubular shank 21 of the outer knob fits rotatably within the said rocker.

The spindle of the lock is formed in three sections, one of which is indicated in general by the reference numeral 45, another by the numeral 46, and the third by the numeral 47. The spindle section 45 consists of a stem which is rectangular in crosssection and which is provided at one end with a pyramidal head 48. The head 48 is received within a correspondingly formed opening 49 and a disk 50 which is secured tothe inner end of the barrel 52 of a keyoperated tumbler mechanism which is designed for actuation to rotate the spindle section For a purpose to be presently explained this disk 51 is provided upon its periphery with a radially projecting lug 52. The barrel is rotatably carried within a casing 53 which has one end fitted as at 53 in an opening formed in the section 16 of the outer knob, the said section having a flange 53 which is overturned about a circumscribing rib 53 formed upon the casing 53. The casing 53 is formed with a number of openings 54 which extend in a series longitudinally of the casing, and at points diametrically opposite the ,openings 54 with openings The barrel 52 has a key-slot 66 extending therethrough and intersected by a. number of recesses 57 in which are fitted the tumbler pins in a manner which will now be described. Each of the recesse's 57 is widened as at 58, whereby to afford, a shoulder 59 located near one end thereof. Each ,of the tumbler pins is indicated by the numeral 60 and each has a laterally porjecting lug 61 against which bears one end of a spring 62 which is housed Within the widened portion of the recess in which the respectivetumbler pin is seated, the other end of the spring bearingagainst the shoulder 59, as clearlyshown inFig. 13 ofthe drawings. That side of each tumbler pin 60 opposite the s'idefrom which the ,lug 61 projects is recessed as" at '60 to form laterally-projecting heads 60 and 60 located respectively at the upper and lower ends of the pin, the head 60 being beveled upon its under side as indicated at 60 the head 60 extending a greater distance outwardly than the circumferential radius of the under surface of the lug 61, this head projecting a greater or lesser distance into the recesses 54 of the casing 53.

By referring to Figs. 13 and 14 it will be observed that the heads 60 of the latchpins 60 have their upper ends normally located a greater or less distance inwardly of the circumferential surface of the barrel 52 and that the springs 58 normally hold the pins with the heads 60 projecting into the openings 54 in the casing 53, the barrel 52 being in this manner held against rotation in the said casing, although it will be seen that upon the insertion of a proper key into the slot 56 the beveled under sides 60 of the heads60 will be engaged by the key and the pins will be moved upwardly to such an extent as to bring the lower ends or heads 60 flush with the circumferential surface of the barrel 52 and the barrel may then be rotated in the casing 53. A'shell 63 is fitted upon the casing 53 and serves to exclude dust from the tumbler mechanism above described, and at its inner ends this shell is extended to form a flange 63 the ends of which form shoulders .63 against which the lug 52 upon the disk 50 is designed to engage when the barrel 52 is turned in one direction or the other, the rotative movement' of the barrel being limited by reason of such engagement.

The section 46 of the spindle is in the nature of a sleeve which is formed throughout its length with a bore 64 which is of a contour to snugly receive the squared stem of' the section 45, in the manner clearly shown in Figs. 1, 2, 3 and 10. The section 47 of the spindle is substantially rectangular in cross-section throughout the greater portion of its length, as clearly shown in Fig. 9 of the drawings, and throughout its said portion is threaded at its .corners, as at 65. Throughout the remainder of its length the said section 47 is reduced in diameter, as at 66 and is circular in cross-section. Loosely fitted upon the spindle section 45 is a sleeve 67, the bore of. thissleeve being circular and indicated at 68 and of a diameter to receive the said spindle section 45 for turning movement. The sleeve 67 is provided with a laterally projecting lug70-which is designed to engage in one or another of the notches 44 in the rocker 34. By referring to Figs. 1 and 2 of the drawings it will be noted that .the lug 70 projects through the slot 22 in the knob-shank 21 and that one end of the spindle section. 46 bears I against the said sleeve. A spring 71 is fitted upon the spindle section 45 and bears at one end against the disk 50 and at lts other end against the said sleeve 67 so as to hold the sleeve in position against the spindle section 46. This spring serves also to normally hold the sleeve 67 in position with its lug 70 engaging in one or another that the lug 70 projects through the slot 22 and engages in the notches 44, and due to the engagement of the rib 26 in the slot 22, rotation of either knob in either direction, when the lug 70 is engaged in any of the notches 44 will serve to retract the lock-bolt. It will be apparent, however, that when the lug is not in engagement in any of the notches 44 either knob may be rotated in either direction without in any way affecting the latch-bolt.

For a pur ose to be presently explained a sleeve-nut 2 is threaded on the squared portion of the spindle section 47 and this sleeve nut' constitutes an adjustable abutment for that end of the spindle section 46 opposite the end which is engaged by the sleeve 67.

Thereduced end 66 of the spindle section 47 fits within the stem 76 of a push-button 77.

This button 77 is mounted for sliding movement in a cylindrical stamped-in portion 78 of the cap-section 24-of the inner knob and is normally held in the position shown in Fig. 1 25- of the drawings by means of a spring 79 which bears at one end against the back of the button and at its other end against lugs 80. which are stamped-in at diametrically opposite points from the inner end of the portion 78. The cap-section 24 of the knob at the outer end of its portion 78 is stamped or otherwise formed with a rib 81 against which abuts the peripheral portion of the button 7 7 By s0 mounting the button, pressure inserted against it in the manner illustrated in Fig. 2 of the drawings will result in the section 47 being slid to the right in Fig. 1 of the drawings, correspondingly moving the section 46 and the sleeve 67 whereby to move the lug 70 out of engagement in the notches 44 in the rocker 34.

It will be apparent that due to the provision ofthe sleeve-nut 72 the several sec- 45 tions of the spindle may be adjusted with respect to each other so as to permit of the lock being mounted upon a door of any thiclmess within reasonable limits and for a purpose which will be presently'pointed out 5.0 a collar 82 is arranged upon the squared portion of the spindle section 47 at that end thereof adjacent the reduced portion 66 'of i the saidspindle section, and a pin 83 is fitted through the said collar 82 and the said spindle section whereby to hold the collar in place. The collar is formed upon its under side with a lug 84 having a beveled under face 85, the forward end of this lug constituting a shoulder or abutment for engagement with a member of a detent device which will now be, described.

In connection with the spindle consisting of the several sections above described, the invention contemplates the provision of a detent device for holding the spindle section 47 in such' position that the lug will be disengaged from the notches 44 and this device will now be specifically described. The detent mentioned above is in the nature of a plate 83 having its lower end bent back upon itself at an angle as at 84 and bifurcated as at 85. A rivet 86, or the like, is secured upon the interior surface of the section 23 of the inner knob and fits within the bifurcation 85 in the manner illustrated in Figs. 1 and 2 of the drawings.

The plate 83 is formed with an opening 86, the lower portion of which is substantially circular and the upper portion is of segmental outline, as indicated at 87. A portion of the shell-section 23 is struck-in as at 88 and fitted between this portion and the corresponding portion 24 are the ends 89 of a leaf-spring 90, the end-portions of the spring being bent back at an angle toward each other as, at 91 and secured in such position that the body portion of the spring will extend along a line which is a chord of the circle described between the portion 25 of the section 24. At a point midway between its ends the body portion of the spring is struck-up so as to form an upstanding lug 92. At its upper end the plate 83 is formed with a forwardly projecting tooth 93 which rests upon the upper surface of the body portion of the spring 90 and is designed to engage the said surface at one side or the other of the lug 92. .The plate, beside the tooth 93 is bent to extend rearwardly at right angles to the plane of the body portion of the plate, as at 94, and thence to extend upwardly as at 95, this latter portion fitting within a finger-piece 96 having an arcuate base 97 which serves to close a slot 98 in which the finger-piece works, this slot being formed in the upper side of the section 23 of 'theinner knob in the manner illustrated in Fig. 1 of the drawings.

By referring to Figs. 4, 5 and 7, it will be observed that the lower or circular portion of the opening'86 is arranged to conform to the cross-sectional contour of the collar 82 and that when the wedge-shaped lug 84 is uppermost this collar may pass through the opening, the lug passing through the upper or segmental portion of the opening. However, it will be observed by referring to Fig. 4 of the drawings that when the collar- 82 is rotated to position with its lug facing downwardly, when the detent is in normal position, the forward end of the lug will rest against the rear face of the plate 83*. It will further be observed from inspection of Fig: 5 that should the plate 83 be swung to the right to assume the position illustrated in the said figure, the end of the collar 82 will abut against the rear face of the deagainst movement to assume the position shown in Fig. 2.

In order that the inclined face of the lug 84 may readily pass over the wall of the opening 86, the face ofthe plate is formed with an arcuate rib- 98' which is convex in cross section and which extends along the lower side of the said opening.

The lock-strike employed in connection with the locl:,-aboye described, consists of a plate 99 which is formed near its upper and lower ends withslots lOO and this plate is formed between the slots 100 with a relatively wide-slot 101=and at one side of this slot is thickened asat 102 and-extended to form a tongue 103 which is curved laterally so as to permit of the ready movement of the loclebolt into engagement with the strike. A plate 104, is disposed against the .plate 99 andin one side is recessed asat 105, the upper andlower walls of the recess being beveled as at 106 and slidably receiving between them the'thickened portion 102 of the plate 99. Screws 107 are fitted through openings 108 formed. in the .plate 104 and project through the slets 100 and are threaded into the door trame in the usual -manner. It will be observed that the plate 104 is formed at one edge'with a laterally projecting flange 109 which closes the space between the-face of the. plate and the edgeface of the door and this flange prevents the insertion of a knife, or the like, between the door and'the strike for the purpose of shifting the lock-bolt to released position.

l[t ,will be readily understood that by ad;

justing the plate 104: upon the plate 99, the position of that wall of the opening of the strike, against. which the lock-bolt engages, may be varied sowthata snug engagement may be secured between these elements.

L It will be understood by referring to Fig. 1 of the drawings that. with the parts in the position shown. in this figure a rotation of either knob in one direction or the otherwillresult. in the lock-bolt being retracted-from locking engagement :with the lock-strike and consequently the door may be opened from .within or from Without when the parts are so relatively-positioned. Should it be desired to'lock the door so that it could only be openeditr'om .without by the use of a proper key, the button 77 is;-,pressed inwardly as indicated in Fig. 2 of the drawing and against the tension of the spring 79.

- This movement of: the button will result in a cor-responding -mot ement of the collar-82 and as the wedge-shaped lug 84 upon this collar rides over the lower side of the wall of the opening Bfiflthe detent-plate 83 will be moved downwardly against the tension of the spring'90 and the abrupt end of the said lug '84 will engage behind the detentplate in the manner shown in Fig. 2 of the drawings. As soon as the button 77 is relieved of pressure, it will be automatically returned to the position shown in Fig. 2 of the drawings through the medium of the spring 79. The movement of the collar 82 and the section -17 of the lock spindle, above described, will result in a corresponding movement of the section 4-6 together with the sleeve 67 so that the lug 7 0 will be moved out of engagement in the notches in the rocker of the lock. With the parts thus po-. sitioned, either knob may be turned in either direction without ,in any way affecting the lock-bolt. It will be understood from inspection of the drawings that the three sections of the spindle are connected for rotation in unison so that should either of the sections be rotated, the others would be similarly moved. Consequently, should the proper key be inserted into the barrel 52 and should the key be turned so as to rotate the barrel, a similar movement will be imparted to the section L? of the spindle and if this 'lnovement is continued until the abrupt end of the wedge-shaped lug 84iregisters with the portion 87 of the opening in the detent 83*, the spring 71 will act immediately to shift the section 4;? in the direction. of the inner knob and to approximately the position shown in Fig. 1 of the drawings. This movement of the spindle sections will result in an engagement of the lug in one.or another of the notches in the rocker of the lock, and rotation of the outer knob will then result in the retraction of the lock-bolt.

, It will be understood that with the parts arranged as abovestated, the detent plate will maintain the positionshown in Fig. 4

.of the drawings.

ment of :the collar 82 until the lug 84 has passed over the lower side of the wall of the 7 opening in the detent-plate 83" and this plate has been returned to normal position, or in other words, the position shown in Fig. 2 of the drawings, in which position the abrupt forward faceof the lug will rest against the respective side of the said detent-plate. The finger-piece is then-swung to the right so as to move the detent-plate to approximately the position-shown in Fig. 5, in which position the end of the collar 82 will rest in engagement with the rear side of the plate at all positions in the rotative movement of the said section of the spindle so that even should a proper or duplicate key be inserted into the barrel-52,,and should the barrel be rotated, the spindle section 47 would at no pointin-its rotativeimovement assume a position which would permit it to be moved through the opening 86"in the detent-plate through the action of the spring 71. To restore the lock to its normal condition, however, it is only necessary to slide the fingerpiece 96 to the left from its position shown in Fig. 5 so that it will assume the position shown in- Fig. 4, after which downward pressure on the finger-piece as in Fig. 6 will release the spindle sections 46 and 47 for forward sliding movement to seat 7 O in the notches in the rocker.

From the foregoing description of the invention it will be seen that there is provided a lock, the parts of which may be readily the lug and quickly adjusted. so as to permit of the nesses and that the screws 5 of the extension bolts are to be threaded onto the sleeves 4 a greater or less distance depending upon the thickness of the door. In adapting the lock for application to doors of different thicknesses, it will of course be necessary to adjust the sleeve-nut or collar 72 upon the spindle section 46, but'aside from this no other adjustment of the lock mechanism is required. I In adjusting the lock for application to a door of a given thickness, the sleeve nut 72 is threaded along the spindle section 47 for a distance equalto a part of the thickness'of the door, after which, the lock can be applied without further adjustment... If desired, a fixed point may be marked upon the said spindle section and a scale designed indicating inches and fractions of inches, and in accordance with which scale, and predetermined point 72the sleeve-nut may be adjusted after a measurement of the door to determine its exactthickness. 5 Having thus described the invention what is claimed as new.'is:-
