LOCK.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed February 24, 1914. Serial No. 820,415.

To all whom it may concern Be it known that I, BERNARD I-I. ZIEHLER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of ()hio, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to looks and more particularly to locks which are designed for use upon doors of stores, store rooms or other places to which several persons have access.

The object of the invention is to provide in connection with a lock a device which will make and preserve a. record of each operation of the locking mechanism to lock or unlock the door, and will indicate which one of the several bolt actuating devices was used in so actuating the bolt.

It is a further object to provide a selective recording device which will be set up and actuated by the manipulation of that particular bolt actuating device to cause a mark indicating a particular bolt actuating device to be made upon a strip of paper or other suitable material.

Further, it is an object of the invention to provide a bolt actuating device which will lvance the record sheet one step upon each operation of the bolt in either direction.

It is further object of the invention to provide a special key actuated mechanism nani nilating the bolt which will make it very d fiicult if not impossible to so alter one key the lock, that it will cause the of another key to be produced.

1 also an object of the invention to provide in connection with this recording 1 inanipul the operation of the look by any unauthorized person in whose hands a key might accidentally or otherwise find its way. Further, to provide this combination or permutation n echanism with a detent to hold the tumbler actuating devices in their inoperative positions while the tumblers are being returned to their normal positions and t1 us prevent the feeling of the combination.

It is also an object of the invention to provide a mechanism of this character which will be very simple in its construction, positive in its operation, and which will require no additional act on the part of the person manipulating the lock in order that the re cording device may be actuated, but in which in recording will automatically and necessarily accompany the operation of the bolt.

In the accompanying drawings Figure 1 is a vertical sectional view taken just inside the front wall of the casing, and showing the mechanism in elevation; Fig. 2 is a sectional view taken just inside the side wall of the casing, showing the mechanism in side elevation; Fig. 3 is a detail view of the lock-out disk; Fig. 4c is a detail of the locking arm for one of the tumblers and Fig. 5 is a facsimile of a record produced by the recording device.

In carrying out my invention I provide a casing forming a main frame upon which the several parts of the mechanism are mounted and which casing may be adapted either to be mounted on the face of a door or to be mounted in a mortise on the edge of a door. Mounted in this casing is a bolt which may be actuated by any one of a plurality of bolt actuating devices. These bolt actuating devices may be in the form of permutation devices, keys, or the combination of keys and permutation devices, and in addition to the device for actuating the look from the out-- side of the door I prefer to provide a bolt actuating device, which may be manipulated from the inside of the door to actuate the bolt to either lock or unlock the door, this inner actuating device not being locked but being free for manipulation by anyone at any time. Mounted adjacent to the bolt and preferably within the casing is a recording mechanism comprising a plurality of separately operable marking devices, each marking device bearing a different symbol and each symbol indicating one of the bolt actuating devices. A selective operating mechanism is provided for actuating that marking device corresponding to the bolt actuating device which is being used to actuate the bolt, and this mechanism is of such a character that it will be automatically set up and actuated by the manipulation of a bolt actuating device. Preferably the record sheet upon which the marks are made is in the form of a strip of paper or other similar material which is fed from a roll into a position to receive the marks and is automatically advanced step by step upon each operation of the recording mechanism.

wall of the casing adjacent to the keeper 3 and is provided at its rear end with a slot 5 to receive a pin 6, secured to the rear wall of the casing or frame and forming a support and guide for that end of the bolt. The movement of the bolt in either direction may be limited in any suitable manner. In the present instance a pin 7 is mounted in the forward portion of the bolt, limiting its out ward movement while the end of the slot 5 contacts with the pin 6 to limit its inward movement. As has been stated, this bolt may be actuated either from the inside or the outside of the door. The two operating mechanisms are necessarily more or less closely connected one with the other, but may comprise separate parts or may comprise to a greater or lesser extent the same parts. In the present arrangement of the mechanism the inside actuating device is in the form of a knob 8, rotatably mounted on the front wall of the casing and having an inwardly extending portion 9, to which is secured a plate 10 having two bolt actuating fingers 11 which are spaced some distance apart. Secured to the bolt 2 and extending between the fingers 11 is a pin 12, the arrangement of the fingers relatively to the pin being such that as the knob is rotated in one direction or the other, one or the other of the fingers will engage the pin 12 and impart movement to the bolt in the cor responding direction. A spring 13 is shown as interposed between the plate 10 and the frame member and tending normally to rotate the plate 10 in a direction to cause the rearmost finger 11 to engage the pin 12. In the present mechanism a separate operating plate is employed for imparting movement to the bolt when the latter is actuated from the outside of the door. This plate is shown in the drawings at 14 as mounted close to the rear wall of the casing and as having spaced fingers arranged to engage the end of the pin 12 projecting beyond the adjacent side of the bolt 2. The plate 14 is operatively connected with a key barrel 16 of a key actuated lock 117 mounted in the door. This lock, in the essential features of its construction, corresponds substantially to the well known Yale lock which has been modified in certain respects to adapt it to its present purpose, and these modifications as well as the manner of connecting the same with the bolt operating plate 14: will be presently described.

Mounted at the casing 1 below the bolt is a recording mechanism having suitable devices for marking upon the strip of paper, as above explained. In the present embodiment of the invention the marking devices are in the form of punches, each of which is shaped to form a different mark or opening in the paper. As here shown these punches are indicated at 17 and are arranged in alinement in a supporting block 18, mounted in the casing and extending transversely to the line of movement of the bolt 2. Each punch has a portion extending above the upper surface of the block 18 and is normally held in its elevated position by means of a spring 19. Arranged beneath the sup porting block 18 is a die or cutting block 20 having suitable openings to receive the respective punches and assist in the punching operation. The punch supporting block and the cutting block are spaced apart a dis tance sufiicient to enable a record sheet which in the present instance is in the form of a strip of paper 21, to be fed between them. A suitable actuating device is pro vided for imparting operative movement to any one of the marking devices or punches 17 and means are provided whereby this actuating device will be set in operative relation with one of said marking devices, and will have operative movement imparted thereto to actuate that particular marking device whenever the bolt 2 is moved in either direction. In the present type of mechanism this actuating device comprises an arm or cam 22 rotatably mounted on a rod 23, rotatably and slidably mounted in the casing 1 and extending parallel with the series of marking devices 17. In the present instance the arm 22 is held normally in a position to operate the marking device corresponding with the knob 8 or inside bolt actuating device. This marking device in the present arrangement of the parts lies adjacent to the inner wall of the casing, and in order to cause the arm 22 to normally occupy a position in operative relation with this particular marking device a spring is provided to move the shaft 23 normally toward such in ner wall of the casing. As is here shown the knob 8 and the inwardly extending portion thereof have a longitudinal bore 2% into which the end of the shaft 23 extends and in which is confined a spring 25 which bears against the end of the shaft 23. Operative movement may be imparted to the cam arm 22 in any suitable manner but this movement is controlled by the movement of the bolt 2, so that an operative movement of the bolt in either direction will cause an operative movement to be imparted to the arm. I prefer that the arm should be directly con nected with the bolt so as to be positively actuated thereby, and in the present embodiment of the invention I have provided the arm 22 with an upwardly extending portion 26 having its upper ends slotted to engage on opposite sides of a pin 15 which is carried by the bolt, thus causing the arm to move with the bolt whenever operative movement is imparted thereto.

Suitable means are provided for causing the setting and operating of the actuating arm 22 for the marking devices when the bolt is actuated from the outside. This may be accomplished in various ways. In the present instance the bolt is controlled'by a permutation locking device, operating in conjunction with a key which latter serves to throw the bolt, and I prefer that the controlling means for the arm 22 should be such that the insertion of the key in the lock will properly position the same to cause the operation of the marking device corresponding to that particular key, and that the rotation of the key will then move the bolt and cause the operation of that particular marking device. In the present embodiment of the invention shaft 23 is operatively connected with the bolt operating plate 14 so that the rotation of this shaft will cause the operation of the bolt, and the arm 22 is so connected with the shaft 23 that it will move with the shaft when longitudinal movement is imparted thereto. In connection with this shaft I have provided a key operated mechanism which will impart both movements thereto. As has been stated this key controlled mechanism corresponds in its main features of construction to the well known Yale lock and I have so shown the same in Fig. 2. This lock is so well known that only a brief description of its main characteristics will be necessary. It comprises a body portion 117 having rotatably mounted therein a key barrel 16, the barrel and casing having formed therein a series of diametrical slots 118, a part of each slot being formed in the barrel and the remainder in the casing or body of the lock. A spring pressed tumbler 27 is mounted in each slot and formed in two parts. In order that the key barrel 16 may be rotated and the bolt of the lock actuated it is necessary that each of the tumblers 27 should be so positioned as to cause the line of division between the two parts thereof to coincide with the line of division between the key barrel and the body of the lock. The lines of division between the two portions of the several tumblers are arranged at different distances from the corresponding ends of the tumblers and in order to properly position them the key is provided with a serrated edge as shown at 28, and when the key has been fully inserted in the lock those portions of the edge thereof which engage the several tumblers will properly position the tumblers as above explained. Rotatably mounted in the casing 117 is a plunger 29 having a transverse groove 30 in its inner end, which groove is adapted to receive a tongue 31 carried by the adjacent end of the shaft 23. The plunger 29 has an extension 32 provided with a recess 33 to receive the end of the key. Consequently when the key is inserted in the key barrel and rotated, the plunger 29 and the shaft 23 will be rotated, and by making the keys of different length longitudinal movement may be imparted to the plunger and to the shaft 23 to properly position the actuating arm 22 of the recording mechanism. The length of the key must be exactly determined in order that the exactmovement may be imparted to the arm 22, or otherwise the operative portion of this arm will overlap the adjacent edges of the two plunger-s and cause both to be operated, thereby indicating on the face of the record that a key which is otherwise correct has been altered as to its length. In order to prevent the use of a key which is not of the correct length I have provided the key barrel 16 and the casing or body portion 117 with additional tumblers 34 and have provided the extension 32 of the plunger 29 with a serrated edge so arranged that when in any one of a series of proper positions the tumblers will be moved in their correct positions, but if the extension 32 is not in one of these proper positions, as when a key has been inserted which does not correspond in length with any of the keys belonging to the lock, the tumblers will be improperly positioned and the barrel held against rotation.

I have also provided means which are preferably directly operated by the bolt for advancing the record sheet step by step upon successive operations of the recording devices. In the present instance a record sheet which, as stated, is in the form of a strip of paper, is fed from a roll 35, supported in the lower part of the casing, and carried across the die block 20 and between feed rollers 36 and 37, one of these rollers being positively actuated to feed the paper forward. In the present instance the upper roller 36 has a ratchet wheel 38, rigidly secured thereto and provided with a pawl 39 to hold the same against backward movement. An operating pawl 40 is pivotally secured at one end of a slide bar 41, the upper end of which is connected with an actuating lever 42. This actuating lever is here shown as having an upwardly extending tapered nose 43, the inclined edges of which are adapted to be engaged by the beveled edges of a tapered portion 44 on the lower part of the bolt. In the present instance the rear lower corner of the bolt is cut away to bevel the same and a transverse V shaped groove is formed in the lower edge of the bolt a short distance from the rear end thereof, thus providing the tapered portion 44. A spring 45 tends to move the slide bar and actuating lever 43 upward and hold the tapered nose thereof in engagement with one or the other of the beveled surfaces of the bolt. Thus when the bolt is moved in either direction that particular beveled surface thereof which is in engagement with the nose of the actuating lever will force the lever down to permit the bolt to ride over the same and will thereby cause the pawl 40 to advance the feed roller 36 one step. This feeding movement takes place at the very beginning of the movement of the bolt and is completed before the opera tion of the marking devices. After the strip of paper passes the feeding roller any suit able disposition may be made thereof, and in the present instance I have passed it through a pair of guide rollers 46 and then through a slot 47 in the bottom of the easing. The guide rollers 46 are not positively driven and as the paper is fed forward it will accumulate in a loop between the feed rollers and the guide rollers from which it may be drawn out through the slot when desired.

In the present embodiment of the invention the bolt cannot be thrown by the use of a key alone but it is necessary to first set the combination of a permutation lock. To this end I have provided a detent 48 arraged to engage one of a series of detents 49 formed in the bolt 2 and held normally in engagement therewith by means of a spring 50. This pawl is provided with an arm 51 which extends downward and forward to a point adjacent to the bolt operating plate 10 which has a pin 52 arranged to engage the end of the arm 51 and move the pawl into an inoperative position when the knob 8 is operated, thus permitting the bolt to be actuated from the inside of the door without the setting of the combination. The movement of the pawl 48 to permit the actuation of the bolt 2 from the outside of the door is controlled by a permutation device, which in its broader features is similar to that shown and described in Patent No. 1078120 granted to me Nov. 11, 1913. This device as shown in the drawings comprises a series of, in the present instance three, rotatory tumblers, which are indicated by the reference numeral 53, and are mounted upon a shaft 54, carried by the casing or frame of the lock. Each tumbler comprises a disk having in one portion of the edge thereof a notch 55 and provided in another portion thereof with a series of notches 56. The notches 56 of each tumbler cotiperate respectively with stops 5? rotatably mounted on the axis of the tumblers and having radial movement to permit the same to be moved from one notch to the other and a spring 58 acts upon each stop to hold the same normally seated. To release the pawl from the bolt it is necessary that the notches 55 in the several tumblers be brought into alinement to receive the projecting portion 59 of a controlling lever 60, which projecting portion extends across the edges of the several tumblers, and is held outward in its inoperative position so long as any one of these tumblers is not in perfect alinement with the other. The controlling lever is provided with a nose 61 engaging a similar nose 62 on the hub of the pawl so that the inward movement of the controlling lever will move the pawl upward and release the bolt. This inward movement is imparted to the controlling lever, when the tumblers are in alinement by means of a spring 63 which is of sufficient strength to overcome the spring 50 which holds the pawl in engagement with the bolt. Thus, as soon as the tumblers are brought into alinement the pawl is moved into its inoperative position and the bolt is free to move.

In order to bring the tumblers into alinement they are all moved rearwardly to bring the stops into engagement with a fixed part of the mechanism, such as a rod 64, and then forward movement is imparted to them one at a time to advance each tumbler the number of steps necessary to bring the notches 55 into alinement. The number of steps which is necessary to advance each tumbler depends upon the position of its stop, and by altering the position of one or more stops the combination can be changed. It will be noted that that portion of each tumbler in which the notches 56 are formed is of less width than the corresponding portion of the tumbler lying behind it and that the numbers for the notches are placed upon the outer face of each tumbler, thereby enabling the numbers on each tumbler to be readily observed and the changing of the combination quickly accomplished. The tumblers may be advanced one at a time from the outside of the door in various manners, but for the purposes of the present look I have provided each tumbler with a ratchet wheel 65 which is rigidly secured thereto. Mounted in the upper portion of the casing above the tumblers are a series of slide bars 66 corresponding in number with the tumblers, which number in the present instance is three. These slide bars are provided with vertical slots 66 through which extend pins 67 to guide the same in their movements. Pivotally mounted on the lower portion of each slide bar is a pawl 68 arranged to engage the corresponding ratchets 65 on the downward movement of the slide bars. Each slide bar is normally held in its elevated position by means of a spring 68. Each slide bar is also provided with an arm 69 arranged to be actuated by a suitable cam or other engaging device to move the slide bar downward against the tension of its spring. In the present instance I have shown the actuating devices as cams 70, there being one of these cams for each slide bar. Each cam is mounted upon a shaft 71 which is mounted in the casing of the lock, extends through the door and is connected on the outside of the door with a suitable actuating device such as a thumb piece 72. In the present instance the cam is so constructed that each complete rotation thereof will impart two movements to the slide bar and the pawl, and to this end I have constructed each cam of two disks or plates hav ing mounted between them on diametrically opposite sides thereof rollers 73 which engage and actuate the arm 69 of the corresponding slide bar when the cam shaft is rotated in either direction. Spring pressed levers 74- bear upon the peripheries of the respective tumblers to retard their movement and prevent overthrow. In order to return all the tumblers to their starting points with the stops in engagement with the fixed part of the frame, I mount a pin 7 5 upon a plate or disk 76 which is mounted on the shaft 54. The shaft extends through the door and has mounted on its outer end a knob 77 by means of which it may be actuated. The bolt can only be operated once upon each setting of the combination. To accomplish this a disk or throwout tumbler 78 is mounted on the axis of and in the rear of the tumblers, and has in its periphery a notch 80 corresponding to the notches 55 in the permutation tumblers. This throwout tumbler is connected with the rearmost tumbler by means of a pin and slot connection as shown at 81, to cause the same to be moved into operative relation with the projecting part 59 of the controlling lever 60 when the other tumblers are set back to their starting points. Thus when the three permutation tumblers have been adjusted to the mechanism above described to bring their notches 55 into alinement they are also brought into alinement with the notch 80 in the throwout tumbler and the lever 60 is permitted to operate. The throwout tumbler is provided in its lower portion with a cut away portion forming a shoulder 7 9 which is so arranged, when the notches 55 are in alinement that the movement of the bolt to its open position will cause a lug 82, carried by an arm 83, mounted on the bolt, to engage the shoulder and move the throwout tumbler a distance suflicient to carry its notch 55 out of alinement with the other notches, this movement being permitted by the pin and slot connection between the throwout tumbler and its adjacent tumbler.

To prevent tampering with the lock and the feeling out of the combination I have provided means for locking the slide bars, which carry the pawls 68, in their elevated positions during the return movements of the tumblers. To this end I have provided each slide bar with a lug 84 adapted to be engaged, when the slide bar is in its elevated position, by a latch 85 which is pivotally mounted at 86 on the casing of the lock. Mounted in the rear of the slide bars 66 is a supplemental slide bar 87 having a stop 88 arranged to engage a finger 89 connected with the latch 85 and move the same inward, on the upward movement of the slide bars 87, against the tension of a spring 90 which tends to hold the latch normally in its outer position. The slide bar 87 is provided at its lower end with a portion which in the present instance is provided with a roller 91, arranged to be engaged by the disk 7 6 which is provided for this purpose with a cam surface, as shown at 92. This cam surface is so arranged that the latch will be actuated as soon as the pin 7 5 is moved away from its normal position. I have shown and described the tumblers as disk shaped and as having the adjusting notches formed in recessed portions thereof, but it will be obvious that this construction is incidental to the arrangement here shown and that the shape of the tumblers is not a material part of the invention, and if they were made in other shapes than circular or disk shaped it might not be nec essary or desirable to provide the same with recesses. Such variations to adapt the mechanism to different embodiments of the invention would require mechanical skill only.

The operation af the lock is as follows. Assuming that the door is locked and the holder of a key wishes to enter, he must first manipulate the thumb piece 72 to set the combination, then insert the key in the lock and rotate the same. The insertion of the key sets the actuating arm for the marking devices of the recorder in a position to actuate that particular marking device corresponding with the key which is inserted in the lock. The rotation of the key then moves the bolt to its open position and the bolt carries with it the actuating arm and causes the marking device to be operated to make a record upon the record sheet 21. At the end of the unlocking movement the bolt may be allowed to remain in its open position when the key is withdrawn, as the person opening the door would usually want to enter and take his key with him. The lost motion between the fingers of the actuating plate for the bolt permits the key barrel to be rotated to a neutral position which will permit of the removal of the key, without disturbing the bolt. The removal of the key permits the spring 25 to move the actuating arm 22 to its normal position, and when the party who has unlocked the door has entered he locks the door by turning the knob 8 which is on the inside thereof. This knob throws the bolt to its closed position and the bolt, which is always connected with the actuating arm 22 regardless of the position of this arm, imparts movement to this arm to actuate that marking device corresponding with the knob. Ihe lost motion between the fingers of the actuating plate for the knob permits the spring 13 to move the pin 52, which is carried by one of the fingers of this plate, out of engagement with the trip arm 51, thereby permitting the pawl 48 to return to locking engagement with the bolt. Should the holder of another key wish to enter while the holder of the first key is within,

EOU

the same operation is repeated and the rec- 0rd shows that the door was unlocked by the holder of key N o. 2 after it had been locked from the inside, thus showing that the holders of the two keys were within at the same time. When the holder of key No. 1 wishes to leave he turns the knob, which causes the trip arm 51 to be actuated to move the pawl 48 from its inoperative position and then moves the bolt to its open position, again actuating the marking device corresponding with the knob. After passing out the holder of key No. 1 inserts his key in the look again setting the actuating arm 22 in a position to operate the marking device corresponding with key No. 1, and then rotates the key to move the bolt to its locked position, again making a record corresponding with that key. If the holder of key No. 2 has passed out along with the holder of key No. 1 this will complete the record, which will appear as shown in Fig. 4 where the pea-r shaped mark represents the knob, the square represents key No. 1 and the dash represents key No. 2. If the holder of key No. 2 remained after the holder of key No. 1 left, then it will be necessary for him to operate the knob to open the door and to use his key to relock it and the record will show these operations. If the holder of one key opens the door from the inside to permit the holder of the other key to leave and then relocks the door on the inside, this will also be shown by the record, which remains in the lock until it is removed by the proper authority at a subsequent time.

It is preferable that some means be provided to prevent the removal and destruction of records by unauthorized persons. One very simple way of doing this is to number the records consecutively. Thus if it is found that a record removed from the lock does not follow consecutively after the last record previously removed by the person authorized to do so it will be obvious that someone has removed a record without authority. I And as the door must have been locked on the outside after the record was thus removed without authority, there will still be some record to show who had operated the lock and destroyed the record.

While I have shown and described one embodiment of my invention it will be understood that this has been chosen for the purpose of illustration only and that I do not wish to be limited to the details of construction shown and described, as obvious modifications will occur to persons skilled in the art.
