COMBINATION-LOCK.

SPECIFICATION forming part of Letters Patent No. 709,078, dated September 16, 1902.

Application filed October 3, 1900. Serial No. 81,856. (No modelfl To all whom it may concern.-

Be it known thatLWiLsoN JOHN CARROLL, a citizen of the United States, residing at Gripplecreek, in the county of Teller and State of Colorado, have invented a new and useful Combination-Lock, of which the following is a specification.

My invention relates to improvements inpermutation-locks, in which we have combined a tumbler mechanism and a slidable bolt with a single spindle, which is adapted to be rotated on its axis and to have an endwise movement for the purpose of individually operating said tumbler mechanism and the latch-bolt.

The object of theinvention is to provide a lock of this character which is simplein construction, efficient and reliable in operation, and cheap ofmanufacture, so that it maybe used as a substitute for ordinary key-operated locks on doors and in other relations.

A further object is to provide an improved structure of this class which dispenses with drop or click tumblers falling into place on proper setting of the permutation members, which operation is objectionable, owing to the fact that burglars and other evil-disposed persons are able by skill and patience to in form themselves of the nature of the combination or permutation members, and thus open the lock.

With these ends in view the invention consists in the novel construction and arrangement of parts, which will be hereinafter fully described, illustrated in the accompanying drawings, and embracedwithin the scope of the appended claims.

In said drawings,in which I have illustrated a preferred embodiment of my invention, Figures 1 and 2 are fragmentary elevations of the opposite sides of a door equipped with my lock. Fig. 3 is a sectional view through a portion of a door, showing one side of the lock-casing removed and illustrating in elevation the mechanism of the loclc with the bolt in the shot position and locked by the permutation members or tumbler mechanism against retraction. Fig. i is a view similar to Fig. 1, with the bolt in its retracted position and with the tumbler mechanism positioned to permit such retraction. Fig. 5is a transverse sectional view through a portion of a door and through the lock on the line 5 5 of Fig. 4, the spindle being shown in operative relation with the bolt. Fig. 6 is a similar view showing the spindle in operative relaiion with the tumbler mechanism. Fig. 7 is a detached elevation of the detachable side of the lock-casing, showing the bolt slidably retained thereon. Figs. 8 and 9 are detail views of the opposed faces of the permutation members or tumblers. Fig. 10 is a detail view of the bolt-throwing disk, and Fig. 11 is a detail View of the detent.

Referring to the numerals of reference employed to designate corresponding parts in the several views, 1 indicates the casing of my improved perm utation-lock, which casing may be of any suitable construction for the purpose of supporting and housing the operating parts; but in the embodiment of the invention selected for illustration in this specification I have shown whatis known asa mortise-lockthat is to say, the casing is fashioned and constructed to belocated within a mortise 2 of a door. One side 3 of this casing is detachable to facilitate access to the interior mechanism, and the front end of the easing is provided witha slot or opening 4, which permits the head of the sliding bolt 5 to play therein and to project a suitable distance from the case for entrance into a keeper upon the door-jamb. (Not shown.) This bolt is illustrated in detail in Fig. 7 of the drawings and is also clearly shown in Figs. '1 and 2, from an inspection of which it will be seen that the boltis a flat and comparatively thin piece of metal with an enlarged head 6 at its front end. The bolt 5 is associated with an impelling-spring 7, which serves normally to project the head of the bolt beyond the front of the casing to adapt it for use as a latch,

inasmuch as it may be actuated by the knobspindle, although, as premised, the bolt is also adapted to serve as a locking-bolt, because its retraction by the spindle may be prevented by the interposition ofthe tumbler mechanism in the path of a part of the-bolt. The impelling-spring 7 is of angular form, as shown in Figs. 3 and l, and is retained with its end in contact with the rear side of the bolt-head 6 by a pair of lugs 8 and 9, extending inwardly from the walls of the casing l. The bolt proper is provided with a longitudilCO , hereinafter.

nal slot of a width proper to receive the knob-spindle and to enable said bolt to have a limited endwise movement independently of the spindle under the repression of the spring7 and also to permit the spindle to have interlocking connection with said bolt under certain conditions, whereby the bolt may be retracted through the rotation ofv said spindle, as will hereinafter appear. This bolt is further provided with recesses, which extend laterally from the opposite sides of the longitudinal slot 10 to form shoulders 11 immediately adjacent to the slot 10 and disposed in the paths of a pair of bolt-engaging studs 12, projecting from one face of a bolt-operating disk 13, mounted upon the spindle adjacent to one side of the bolt and designed, under certain conditions, to be rotated by the spindle to effect the retraction of the bolt through the engagement of the studs 12 with the shoulders 11. Immediately in the rear of the bolt-head 6 and at the horizontal center of the bolt the latter is formed with a tongue 14, said tongue being arranged to enter the boltslots of the tumbler mechanism after such mechanism has been reorganized through the manipulation of the spindle by a person acquainted with the permutation arrangement or combination at which the lock is set. The particular means employed for confining the bolt proper within the casing to permit its sliding movement is not essential, but as one means for effecting this result I have shown therecessed guide-lugs 15 extendinginwardly from the side 3 of the casing and engaging the edges of the thin body portion of the bolt.

The casing l is provided in its opposite sides with alined transverse openings, which coincide with the slot 10 of the bolt, and through these openings and the slot pas es the knob-spindle 16, which is capable of manipulation so as to rotate on its axis and to have a slidable or end wise movement and is provided with a pair of substantially diametrical fingers 17, mounted fast with the spindle, so as to turn or slide therewith at all times. These fingers constitute one embodiment of means for effecting the engagement of the spindle with either the tumbler mechanism or the bolt for thepurpose of setting one and retracting the other in a manner which will be more particularly described The spindle 16 is axially pierced by the knob-stem 17, of rectangular crosssection, and upon the outer ends of this stem are secured the knobs 18, located at opposite sides of the door and spaced from the opposite ends of the spindle 16 by collars 19 and 20. The collar 20 is provided with acircumferential groove 21, arranged to be engaged by 'a sliding detent 22, mounted upon a face or dial plate 23, located upon the inside of the door, and said detent is designed to be slid into position to have its lower'end engage the groove 21 in the spindle-collar for the purpose of retaining the spindle against longitudinal movement, while permitting its rotation for the purpose of actuating the bolt or its idle rotation without effecting the actuation of either the bolt or tumbler mechanism.

The tumbler mechanism which I have devised for service in connection with the knobspindle and the latch-bolt is embodied in the form of a series of disks which are constructed to cooperate with the click-springs, adapted to give an audible indication of the progress of the tumbler mechanism, whereby the employment of clicking tumblers actuated by gravity on the setting of the tumbler mechanism is obviated to overcome the objection hereinbefore mentioned. This tumbler mechanism is shown as consisting of a pair of disks 24 and 25 of the same diameter and mounted loosely on the knob-spindle between the fingers 17 and the bottom or stationary side of the casing, lateral displacement of these tumblers being prevented by spacing-pins 26, projecting from the opposed face of the bolt-operating disk 13, these pins being arranged at points sufficiently remote from the axis of the spindle to remove them out of the path of the fingers 17. The disk 25 is provided in its periphery with a plurality of click-notches 27, and the disk 24 is provided with a single clicknotch 28, and each tumbler-disk is also provided with a bolt-slot 29, which is considerably deeper than either of the click-notches. The disk 24 is provided with an annular groove in its face opposed to the disk 25, and in said groove is mounted an arcuate engaging spring 31, the free end of which is deflected from the face of the disk 24 to be received within an opposed annular groove 32 in the contiguous face of the disk 25. The spring 31 is designed for engagement with the shifting or setting element 33, for the shiftable or adjustable retention of which the disk25 is provided with a circular series of openings 34, opening into the groove 32, to permit the end of the element or pin 33 to extend into said groove to engage the free end of the spring 31 when the disk 25 is rotated in one direction or to click idly over said spring during the opposite rotation of the'disk. The disk 25 is also provided with a pair of nearly diametrically opposite recesses 35, extending from the opening provided at the center of the disk for the reception of the spindle, which recesses are designed in one position of the spindle to be engaged by the fingers 17 to effect an operative engagement between the spindle and the tumbler mechanism for the purpose of permitting the latter to be operated to permit or prevent the retraction of the bolt. The clicksprings 36 are mounted in any suitable manner within the casing to have their free or unconfined ends ride against the peripheral edges of the tumbler-disks and are bent to form' projections 37, which click into the notches 27 and 28 of the disks when said notches are brought into coincidence therewith.

For the purpose of assisting those acquainted with the combination and to constitute an alarm for exposing unauthorized attempts to open the lock I provide a sounder 38as, for instance, a loosely-suspended bar, gong, or other resonantbodyprefe'rabl v mounted upon the inside of the door in position to be struck by a tapper or striker 39, operated through the movement of the knob-spindle. A preferred form of means for effecting the operative connection between the striker 39 and the spindle comprises an index-finger 40, extending radially from a ring 40, surrounding the adjacent knob-shank and adjustably retained by a set-screw or the like. The indeX-finger 40 is designed to have movement in a path obstructed by a trip-arm 41, connected with the striker and arranged to urge the striker against the sounder or gong 38 when swung or tripped by the passage of the finger through the rotation of either knob. The striker 39 and its trip-arm 41 may be formed from a strand of wire bent to form the striker and trip-arm, a loop 42, surrounding a pin 43, extending from the dial-plate 23 and an engaging end 43", retained by a similar pin, as shown in Fig. 2 of the drawings.

Attention may be called at this point to the specific construction of the detent 22, which is provided with angular slots 22 for the accommodation of retaining-pins 22 said slots being designed to effect an engagement with the pins 22", which will prevent the acciden tal longitudinal movement of the detent after the latter has been dropped into engagement with the spindle and moved laterally to engage the lateral portions 22 of the slots with said pins. Assuming the tumbler mechanism rotary movement of the disk 25 will obvi ously remove the bolt-slot 29 in said disk from its position in line with the tongue 1.4, and continued movement of these parts in the same direction will cause the shiftable member 33 to be brought into contact with the end of the spring 31 to communicate motion to the disk 28, which will obviously effect the removal of the key-slot 29 in the disk 24 from behind the tongue. The tumbler mechanism will thus be unset, and the bolt will be securely located in its shot or engaging position until such time as the keyslots in the disks shall be brought into alinement with each other and with the tongue 14. The effectual locking of the door is now completed by drawing the spindle back to its normal position, where it will be retained by the detent 22 engaging the aunulargroove 21 in the spindlecollar 20. With the lock thus assembled it will be impossible for an unauthorized person to open the door, because the spindle must first be pulled endwise to bring. the pins 17 into engagement with the tumbler mechanism, and'after this is effected the combination determined by the position of the shiftable element 33 upon the disk 25 must be known before the tumbler mechanism can be operated to effect the alinement of the keyslot 29 with the tongue 14. If, however, it is intended that the lock shall be capable of operation by an authorized person understanding the combination, the detent is drawn up out of engagement with the spindle, as shown in Fig. 6 of the drawings. This will permit the outside door-knob to be manipulated for the purpose of moving the spindle endwise to the position shown in Fig. 6 to engage the pin 17 with the recesses 35 within the disk 25. The knob is then turned to the right until the sounder is sounded twice, the second sounding being the starting-point from which the known combination is to be worked. The purpose of rotating the knob until the striker is tripped twice is to insure a complete rotation of the disk 25, so that before the working of the combination is started the connection between the pin or shiftable element 33 and the end of the spring 3 will be efiected to insure the actuation of the disk 24 by the rotation of the spindle.

Assuming the spring 31 and the key-slot 29 of the disk 24, the pin 33, the finger 40, and the key-slot 29 of the disk 25 to be related, as shown in the drawings, and assuming,further, that the disk 25 is provided with sixteen peripheral notches, including the key-slot, the knob is turned fourteen clicks from the starting-point, which will position the disks 24 and 25, as shown in Fig. 3 of the drawings, the disk 34 having its key-slot 29in alinement with the tongue 14 and its notch 28 engaged by one of the click-springs. The knob is now turned in the opposite direction until six clicks are heard, the significance of these sounds being that the disk 25 is moved independently of the disk 24 to present its key-slot 29 in alinement with the key-slot 29 of the disk 24 and immediately behind the tongue 14. Thus the setting of the tumbler mechanism is complete, inasmuch as both disks are retained by their click-springs in position to permit the retraction of the bolt. The spindle is now forced endwise to disengage the pins 17 from the recesses 35 of the disk 25 and to effect an operative engagement between said pins and the bolt-disk 13 by 10- cating said pins between two teeth of an annular series of projections or teeth 41 upon 1 the adjacent face of the disk 13.

The spindle may now be rotated for the purpose of retracting the bolt against the resistance of the spring 7. In this position of the parts the bolt may beoperated at will by the manipulation of the knob in the manner of an ordinary latch-bolt; but whenever it is desired to lock the bolt in its'shot position it is simply necessary torepeat the operation hereinbefore described for the purpose of unsetting ,the tumbler mechanism to prevent the retraction of the bolt except by an authorized person. While this method of manipulation of the lock is effective and may be desirable in some instances, it requires considerable concentration to follow the sounds or clicks,

which must be accurately noted for the purpose ofvdete'rmining the position of the look while working out the combination. I therefore prefer to provide for a visual indication of the position of the parts. To this end I provide the dial-plate 23 and index-finger 40, a similar dial 44 and a second index-finger 45 being mounted, respectively, upon the outside of the door and upon the adjacent knobshank. The dials are provided with numbered graduations corresponding to the number of peripheral notches in the disk 25, and the index-fingers are disposed in corresponding positions, so that an authorized person outside of the door after having turned the knob until the sounding of the alarm indicates the starting-point may be guided in turning the knob-spindle by the graduations upon the scale, it being simply necessary to know the position upon the dial which must be assumed by the finger in order to properly position the key-slot of the disk 24 and the position which must be assumed thereby through a reverse movement of the knob in order to aline the key-slot 29 in the disk 25 with that of the disk 24 for the purpose of positioning the parts for the retraction of the bolt, as shown in Fig. 4 of the drawings. It will therefore appear that the use of the dials and index-fingers obviates the necessity for following the audible indication of the progress of the cooperating elements; but by the employment of the construction described both visual and audible indications are provided for the guidance of an authorized person in setting the lock for operation.

In conclusion, attention may be directed to the special utility for that arrangement of the fingers 17 with respect to the bolt-operating disk and tumbler mechanism, which permits the fingers to engage either the bolt-operating disk or the tumblers or neither of them, as desired. Ordinarily where a shiftable spindle is employed it is of necessity connected .with either one or the other of these mechanismsthat is to say, it'is either connected with the bolt or with the tumbler-and is incapable of idle movement entirelyindependent of either of these elements of the look. In the present invention, however, the provision of the recesses 35 in the tumbler for the reception of the fingers 17, as distinguished from the usual method of having the projections upon the face of the tumbler, compels the operator to first bring the pins opposite the recesses and then force the spindle endwise to effect the engagement, and unless, therefore, a person is acquainted with this peculiarity of the lock he will be unable to effect its manipulation, even though he is acquainted with the usual form of locks of the shiftable-spindle type-that is to say, supposing the detent is not in its engaging position to hold the spindle against endwise movement and'that a person unacquainted with the lock, but recognizing the shiftable spindle, endeavors to effect an entrance, his first move will naturally be to shift the spindle to what appears to be its tumblerengaging position, but which in this form of the lock would be that position in which the fingers 17 will clear the ends of the projections above the bolt-operating disk, and the result will be that the spindle will rotate idly and without giving an unauthorized person the slightest clue as to the manner of effecting the engagement between the fingers and the tumbler. A still further utility of this idle movement is that an authorized person may, after casting the bolt, shift the tumblers to any desired position, and by noting the position of the indicator-finger 40 upon the dial maybe able whenever he desires to open the lock and insure the alinement of the fingers 17 with the recesses 35 by simply bringing the finger 40 again at the place upon the dial which has been previously noted. After having set the tumblers in the manner specified the spindle may be shifted sufficiently to bring the fingers out of engagement with both the tumblers and the bolt-operating disk, and after the spindle has thus rotated idly to carry the fingers 17 out of alinement with the recesses 35 the unauthorized operator can manipulate the spindle only in two ways: first,

by shifting it endwise into engagement with.

the bolt-operating disk, which is held stationary by the bolt, and, second, by shifting the spindle back again and rotating it idly, it being impossible to effect the engagement between the fingers 17 and the tumbler without first locating them opposite the recesses 35 and then pushing the spindle endwise in a manner which will be Well understood. A still further utility for'this feature resides in the fact that instead of the unauthorized person being permitted to operate the tumbleroperating mechanism at liberty when the detent is raised he is encountered with the very delicate problem of first efiecting an engagement between the tumbler mechanism and the spindle, as this connection is not only effected by the endwise movement of the spindle, but also by the rotary movement thereof to aline the fingers and recesses and the subsequent additional endwise movement which is necessary to effect the engagement.

From the foregoing it Will be observed that I have produced a novel and highly efficient combination-lock embodying avconstruction best calculated to effect the accomplishment of the several objects stated; but while the present embodiment of the invention is believed at this time to be preferable I do not wish to limit myself to the structural details defined, as it is obvious that many changes,
