  • This invention relates to locks, and more particularly to recording locks, which make a record pertaining to the manipulation of the bolt.
  • the object of the invention is to provide means to prevent the tampering with or 1fradulent manipulation of a lock of this nn To this end it is a further object of the invention to provide means whereby it is necessary to completely move the bolt inone direction and to make a record each time the key is operated.
  • a further object of the invention is to provide means for preventing the device from being manipulated to wind off all the paper without making any record thereon, thereby permitting the lock to be subsequently operated without a record being made.
  • Figure 1 is an elevation of one side of a lock with the casing in section;
  • Fig. 2 is a'vertical, sectional view taken through the casing near the edge of the door and showing the mechanism in elevation;
  • Figs. 3, 4 and 5 are detail views of the bolt locking and key controlling devices showing the same in successive positions;
  • Fig. 6 is a detail view of the full stroke mechanism for' the platen;
  • Fig. 7 is a plan view of the clock show ing the retaining device therefor.
  • the plate 1 is usually arranged on the inner side of the door and the mechanism carried by that plate is inclosed in a casing 5 which may be of any suitable character and is preferably movable in part or in whole to afford access to the interior of the mechanism.
  • the plate 2 is arranged on the outer side of the door and the mechanism carried thereby is supported between the two plates lin a recess or aperture formed in the door.
  • the bolt is shown at 6 and is slidably mounted on the plate 1 by means of pins 7 extending through horizontal slots 8 formed in the bolt.
  • Suitable actuating devices are provided forimparting movement to this bolt and, in the present instance, these devices comprise two similar vbut independently operable actuating members 9 and 10 which are pivotally mounted on a common axis, and are provided with portions or arms extending on the opposite sides o-f said axis and having their upper edges inclined-upwardly and outwardly from the axis to provide cam surfaces 12 and 13 which are so arranged that when movement is imparted to.
  • actuatingl members are, as has been stated, separately movable, and, in the construction here shown, the members areV respectively connected with actuating knobs l5 and 16. These knobs are here shown as conventional round knobs, but it will be understood that the term is intended to include any kind of a manually operated device which may be substituted for these lic knobs.
  • the knob 15 is connected to the actuating member 9 by a shaft 17 extending through a suitable bearing 18, formed in the casing 5, and is rigidly secured to the member 9.
  • This knob which is arranged on the inner side of the door, is, usually, free to rotate and the bolt may be actuated by this knob at any time without the use of a key or other releasing device.
  • each operation of the knob produces a record.
  • the knob 16 is connected with the actuating member 10 by means of ashaft 19 which is rigidly secured to the actuating member, extends through the plate 1 and has a part extending into a hollow spindle 2O rigidly secured to the knob 16 and forming a support therefor, this spindle being journaled in the frame member or plate 2.
  • connection between the shaft 19 and the spindle 20 is a slip connection, that is, it is such as to hold these parts against relative rotary movement but to permit them to be slipped apart when the plates 1 and 2 of the main frame are disconnected. This is accomplished, in the present instance, by providing the shaft 19 with a longitudinal slot 21 and mounting a pin 22 in the hollow spindle 20 in a position to enter the slot in the shaft when the latter is inserted in the spindle.
  • the bolt is normally locked against movement in either direction, to prevent it being shifted by means other than the bolt-actuating devices. This is accomplished by providing the bolt in its upper edge with a series of teeth 24 with which ccperate two oppositely extending pawls 25 and 26, both of which normally engage the teeth 24. Connected with the pawls 25 and 26 are arms 27 and 28 which preferably are mounted on the same axes with the respective pawls and rigidly secured thereto. A spring 29 connects the arms and holds the pawls normally in engagement with the teeth 24.
  • the outer ends of the arms of the two actuating members 9 and 10 are cam shaped, as shown at 30 and 31, and the ends of the arms 27 and 28 are so arranged with relation to these cam shaped surfaces 30 and 81 that when one of the actuating members is moved the outer cam surface, 30 or 31, will engage the adjacent arm, 27 or 28, and release the ⁇ corresponding pawl before the cam surface, 12 or 13, engages the pin 14, thus releasing the bolt for movement in the desired direction before the operative connection between the actuating device and the bolt is established.
  • the bolt is provided with recesses 82 and 38 so arranged that when the bolt is in its retracted position the recess 82 will be in a position to receive the pawl 25 and when the olt is in its projected or operative position the recess 33 will be in a position to receive the pawl 26. Consequently, the arm, 27 or 28, as the case may be, will be moved beyond the position which it occupies when the pawl is in engagement with the teeth 24 of the bolt.
  • the recording mechanism which coperates with the devices here shown may be of various kinds but that which has been chosen for the purposeof illustration consists of a clock 84 having a time registering device from which a record of the time can be taken.
  • this device is of a known construction and consists of a printing dial 85 from which a record may be taken showing the time at which s'uch record was taken.
  • a platen 36 having a plunger or body portion 37 slidably mounted in a vertical bearing 88 and adapted to receive operative movement from the actuating device for the bolt.
  • this operative movement is imparted to the platen by means of a plate 89 which is operatively connected with the platen and is held normally in its elevated position by means of springs 40.
  • the plate 39 extends transversely of the frame and is arranged beneath and adjacent to the two actuating members 9 and 10 which are provided along their lower edges with parts, such as the antifriction rollers 41, to engage the plate and force the same downward when movement is imparted to either of the actuating members. These rollers are spaced such distances from the axes of the actuating members as will give the desired movement to the platen.
  • the plate 39 may be of anyy shape orV character which will enable it to coperate in the desired ⁇ manner with the actuating members.
  • the plate 39 is rigidly secured to and guided by a pin or plunger 42 which is mounted in a guideway formed in the bearing block 38 which carries the platen.
  • the connection between the plate 39 and the platen may be of any suitable character, but, as here shown, the connection is a cushioned one and the plunger1 37 of the platen is provided with a recess in which is slidably mounted a stem 43, the upper end of which is provided with an annular groove 44 to enable the same to be inserted in a.
  • the record sheet or strip may be mounted in any suitable manner. In the present instance it consists of a web of paper 47 mounted on a roll 48 on one side of the platen and eX- tending about guides 49 and 50 to a receiving roll 52.
  • a suitable transfer device such as the ink ribbon 53, which is wound upon spools 54 on opposite sides of the form and passes about guides 55 to position the same with relation to the form.
  • Springs 56 pressing against the spools 54 hold the same normally against unwinding.
  • the feeding of the ribbon may be accomplished in any suitable manner, but, as it does not require frequent adjust ment, we have, in the present instance, merely provided the spools with knurled knobs 57 by means of which the adjustment may be made by hand.
  • the paper feed may be accomplished in any suitable manner but it is preferable that the paper should be fed forward automatically upon cach operation of the platen and we have, therefore, provided a feeding mechanism which is actuated upon each movement of the platen.
  • the receiving roll is provided with a pinion 58 which meshes with a toothed rack 59 formed on a lever 60 pivotally mounted on that side of the platen opposite the receiving roll.'
  • This lever 60 is connected with the platen to cause operative movement to be imparted thereto by the movement of the platen.
  • This connection is formed, in the present instance, by providing the lever with a cam slot 6l into which projects a pin 62 carried by the plunger 42 of the plate 39. If the feed mechanism were operated throughout the movement of the platen it would, in the present machine, result in the feeding of too much paper and we have, therefore, so
  • a pawl and ratchet mechanism may be actuated onlyv upon the movement of the lever 60 in one direction the pinion 58 is connected to the roll byy a pawl and ratchet mechanism, as shown at 63.
  • this full stroke device comprises a pawl 64 pivotally mounted on the bearing block 38 adjacent to the plunger 42 ⁇ and adapted to engage teeth 65 formed in the edge o-f the plunger.
  • a spring 66 tends to move the nose of the pawl normally toward the teeth and the pawl is so arranged that upon the first downward movement of the platen it will engage one of the teeth and prevent the return movement of the platen.
  • the latter is provided at its upper end with a finger 67 arranged to be engaged by a projection or tripping block 68 secured to the plate 39. The relative positions of these two parts are such that the pawl will betripped just as the platen completes its movement, thereby releasing the platen for return movement.
  • a detent 69 is provided having a squared upper end, one corner of which is adapted to be moved into and out of the path of a projection 70 at the lower end of the pawl 64.
  • a spring 7l tends to move the detent in a direction to move this corner or nose into the path of the projection. Consequently, as soon as the pawl has been moved into its inoperative position the detent will engage the projection 70 and retain the pawl in its inoperative position during the upward movement of the platen.
  • the platen is provided with a cam 72 so arranged that it will engage the detent and force the same out of engagement with the nose of the pawl just as the platen reaches its uppermost position.
  • the actuating mechanism which is controlled from the outside of the door, that is, the actuating member l0 and the'knob 16, are normally locked against movement and can be released only by means of a key.
  • suitable key-controlled devices are provided which are of such a character that they not only control the movements of the bolt actuating mechanism, but also prevent the removal of the key from the lock except when the bolt is at one limit of its movement and the actuating mechanism is in its normally locked posi tion.
  • These key-controlled devices may be of various kinds, but those shown in the present embodiment of the invention are very efficient.
  • the spindle 2O of the knob 16 has rigidly secured thereto a locking member which is here shown in the formvof a disk 78 having a notch 74: adapted to receive a nose 75 of a locking arm or lever 76.
  • This lever is pivotally mounted on the frame member 2 with its nose 7 5 normally in the notch of the locking disk and is acted upon by a spring 77 tending to move the nose 75 out of the notch of the locking disk.
  • the nose 7 5 is positively held in the notch of the locking disk, this being accomplished, by providing ⁇ the arm 76 with a projection 78 arranged to ride over the edge of a cam disk 79 which is controlled by a key.
  • the disk 79 is adapted to be rotated by the key, and is preferably rigidly secured to a rotatable part of the lock, such as a key barrel 80.
  • the key and key barrel may be of any suitable construction but, in the present instance, we have employed the well known Yale type of lock and key.
  • the shape of the cam disk 79 is such that when partial rotation has been imparted to the same by means of the key the higher portion of the cam will move out of engagement with the projection of the arm 76 and will permit the arm to move under the inuence of the spring 77 to withdraw the nose 75 from the notch, thus releasing the bolt actuating device for operation from the outside of the door.
  • the disk 79 is provided in lits periphery with a notch 8l adapted to receive the end of a finger 82 pivotally mounted on the frame l and, in the present instance, on an axis coincident with the aXis of the arm 76.
  • the arrangement of the notch 8l and the finger 82 with relation to the cam surface of the disk is such that the finger will enter the notch when the cam surface has moved into a position to permit the releasing of the bolt-actuating device.
  • the knob may be turned in either direction but after it has been started in one direction its movement in that direction must be completed before it can be returned to its normal position, this being accomplished by a full stroke mechanism 83 of a well known type.
  • the finger 82 is held in its notch by the action of a spring and, in the present instance, the spring 77 is utilized for this purpose.
  • the finger 82 has connected thereto a second finger 84 extending alongside of the arm 76 and having a pin 85 which projects through a slot 86 in the arm 76 and affords means for connecting the spring 77 with the linger 84.
  • This finger 84 also has a projection 87 which rides over the periphery of a cam 88, this cam being rigidly secured to the hollow spindle 2O of the knob.
  • this same cam disk 88 is utilized as a part of the full stroke mechanism 83. That portion of the cam disk 88 adjacent Vto the notch 74 is of short radius so that the spring is free to move the finger 84 about its axis to cause the finger 82 to enter the notch 8l when the key is actuated.
  • the cam disk 88 forces the arm 84 downward against the tension of the spring 77 and thus moves the finger 82 out of the notch 8l.
  • the projection 78 of the arm 76 lies in front of the high portion of the cam disk 79, that is, the portion having the longer radius, as shown in Figs. 4 and 5, and inasmuch as the nose 75 of the arm bears against the periphery of the locking disk 7 3 the engagement of the cam disk with the projection 7 8 effectually holds the cam disk and, consequently, the key barrel against movement to their normal positions.
  • the cam disk does have a slight movement before it comes into locking engagement with the projection of the arm and this movement is suiiicient to move the notch out of alinement with the finger 82. Therefore, after the movement of the bolt has been completed and the bolt-actuating devices are being returned to their normal positions, thus moving the .short radius 130 portion of the cam disk 88 into alinement with the projection 87 of the finger 84, the end of the finger 82 will engage the periphery of the disk 79 adjacent to the notch 81 and will, consequently, ride over the disk when the same is otherwise free for further movement.
  • This device effectually prevents any manipulation of the bolt without imparting a full movement thereto and thus causing a record to be made and it will be noted that by the use of the two retaining devices 82 and 78 the key barrel is held against movement to its normal position until the bolt-actuating devices have been returned to their normal positions, but at the same time the key barrel is free to return to its normal position as soon as the bolt-actuating devices have reached their normal positions.
  • the movement of the key barrel in both directions is positively limited by a stop arranged between two shoulders 91 and 92 formed on the cam disk 79.
  • the mechanism is also adapted to print the identification of the particular key which was used to manipulate the lock.
  • the recording device has a second form 93 which is in the nature of a sliding bar arranged adjacent to the time disk and bearing type adapted to print initials, numbers or other identifying marks of the respective keys. These marks are arranged lengthwise of the type bar and are moved successively into printing position by 'the longitudinal movement of lthe bar. This movement may be imparted to the slide bar by the keys, as shown by key 102 in Fig. 2.
  • the bar is held in its retracted position by a spring 94 and is provided with an enlarged end 95 arranged to be engaged by the keys when they are inserted in the barrel and in order that a diiferent amount of movement may be imparted to the bar by the different keys the different keys are of different lengths. Consequently, each key willmove the type bar in such a position that a different mark will be printed.
  • the clock mechanism may be supported in any suitable manner but, as here shown, comprises a rectangular frame consisting of upright posts 96.
  • Thel two posts 96 adjacent to the frame member 1 are provided with openings to receive pins 97, onto or olf of which the frame may be slipped when the casing has been removed.
  • a spring-actuated latch 98 having a nose 99 adapted to extend through an opening 100 in the frame member 1 and to engage over the edge of the frame member and thus retain the clock in position.
  • a finger piece 101 eXtends into a position in which it may be engaged and actuated to release the latch when it is desired to remove the clock.
  • the operation of thevmechanism will be Vunderstood from the foregoing description and it will be apparent that the device is very simple in its construction and positive in its operation; that it is safe guarded against fraudulent manipulation by making it impossible to remove the key until a record has been made, or to otherwise manipulate the machine in such a way as to make a fraudulent record or to avoid making any record when the bolt is actuated. Further, it will be noted that the mechanism is all carried on the two parts of the frame and that the lock may be completely assembled at the factory. To attach the same to a door it is only necessary to provide'the latter with an opening or recess to receive the parts carried bythe frame member 1v and to permit the passage of the connecting bolts and the shaft 19.

Specification of Letters Patent. Patented Jan., 16, 191'?,
Application sied February 20, 1915. serial ivo.V 9,714.
To all whom t 'may concern:
Be it known that we, BERNARD H. ZIEHLER and D. RAY Rown, citizens of the United States, residing at Dayton, in the county of Montgomery and State vof Ohio, 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 locks, and more particularly to recording locks, which make a record pertaining to the manipulation of the bolt.
' The object of the invention is to provide means to prevent the tampering with or 1fradulent manipulation of a lock of this nn To this end it is a further object of the invention to provide means whereby it is necessary to completely move the bolt inone direction and to make a record each time the key is operated.
Further, it is an object of the invention to provide means for preventing two successive i movements of the bolt-actuating devices in the same direction, thus causing a second record to be printed when there has been no actual movement of the bolt.
A further object of the invention is to provide means for preventing the device from being manipulated to wind off all the paper without making any record thereon, thereby permitting the lock to be subsequently operated without a record being made.
It is also an object of the invention to provide a device of this character which will be very simple in its construction and operation; which will be of a strong,.durable character; which can be manufactured atk a low cost; and which may be easily applied to a door.
In the accompanying drawings, Figure 1 is an elevation of one side of a lock with the casing in section; Fig. 2 is a'vertical, sectional view taken through the casing near the edge of the door and showing the mechanism in elevation; Figs. 3, 4 and 5 are detail views of the bolt locking and key controlling devices showing the same in successive positions; Fig. 6 is a detail view of the full stroke mechanism for' the platen;
and Fig. 7 is a plan view of the clock show ing the retaining device therefor.
In these drawings. We illustrated. one
having mounted thereon spacing sleeves 4.
The plate 1 is usually arranged on the inner side of the door and the mechanism carried by that plate is inclosed in a casing 5 which may be of any suitable character and is preferably movable in part or in whole to afford access to the interior of the mechanism.
.The plate 2 is arranged on the outer side of the door and the mechanism carried thereby is supported between the two plates lin a recess or aperture formed in the door.
In the particular form of the mechanism there illustrated the bolt is shown at 6 and is slidably mounted on the plate 1 by means of pins 7 extending through horizontal slots 8 formed in the bolt. Suitable actuating devices are provided forimparting movement to this bolt and, in the present instance, these devices comprise two similar vbut independently operable actuating members 9 and 10 which are pivotally mounted on a common axis, and are provided with portions or arms extending on the opposite sides o-f said axis and having their upper edges inclined-upwardly and outwardly from the axis to provide cam surfaces 12 and 13 which are so arranged that when movement is imparted to. either of the actuating members in one di-v rection the cam surface 12 of that actuating member which is moved will engage a pin v14 secured to the bolt 6 and move the bolt outward and when either of the actuating members is moved about its axis in the opposite direction the cam surface 13 of that actuating member which is moved will' engage the pin 14 and move the bolt in the opposite direction. The ,actuatingl members are, as has been stated, separately movable, and, in the construction here shown, the members areV respectively connected with actuating knobs l5 and 16. These knobs are here shown as conventional round knobs, but it will be understood that the term is intended to include any kind of a manually operated device which may be substituted for these lic knobs. The knob 15 is connected to the actuating member 9 by a shaft 17 extending through a suitable bearing 18, formed in the casing 5, and is rigidly secured to the member 9. This knob, which is arranged on the inner side of the door, is, usually, free to rotate and the bolt may be actuated by this knob at any time without the use of a key or other releasing device. However, as will hereinafter appear, each operation of the knob produces a record. The knob 16 is connected with the actuating member 10 by means of ashaft 19 which is rigidly secured to the actuating member, extends through the plate 1 and has a part extending into a hollow spindle 2O rigidly secured to the knob 16 and forming a support therefor, this spindle being journaled in the frame member or plate 2. The connection between the shaft 19 and the spindle 20 is a slip connection, that is, it is such as to hold these parts against relative rotary movement but to permit them to be slipped apart when the plates 1 and 2 of the main frame are disconnected. This is accomplished, in the present instance, by providing the shaft 19 with a longitudinal slot 21 and mounting a pin 22 in the hollow spindle 20 in a position to enter the slot in the shaft when the latter is inserted in the spindle. To maintain the axes of the two actuating members 9 and 10 in alinement we have provided the shaft 19 with a portion which extends beyond the face of the actuating member 10 and into a recess 28 formed in the end of the shaft 18, thus supporting the two members in their proper relative positions and permitting them to have free rotary movement relatively one to the other.
The bolt is normally locked against movement in either direction, to prevent it being shifted by means other than the bolt-actuating devices. This is accomplished by providing the bolt in its upper edge with a series of teeth 24 with which ccperate two oppositely extending pawls 25 and 26, both of which normally engage the teeth 24. Connected with the pawls 25 and 26 are arms 27 and 28 which preferably are mounted on the same axes with the respective pawls and rigidly secured thereto. A spring 29 connects the arms and holds the pawls normally in engagement with the teeth 24. The outer ends of the arms of the two actuating members 9 and 10 are cam shaped, as shown at 30 and 31, and the ends of the arms 27 and 28 are so arranged with relation to these cam shaped surfaces 30 and 81 that when one of the actuating members is moved the outer cam surface, 30 or 31, will engage the adjacent arm, 27 or 28, and release the `corresponding pawl before the cam surface, 12 or 13, engages the pin 14, thus releasing the bolt for movement in the desired direction before the operative connection between the actuating device and the bolt is established. To prevent either actuating device being moved twice in the same direction, thus causing a record to be made, as will hereinafter appear, when there is no actual movement of the bolt, we have provided means which make it necessary for the actuating devices to move successively in alternate directions. To accomplish this the bolt is provided with recesses 82 and 38 so arranged that when the bolt is in its retracted position the recess 82 will be in a position to receive the pawl 25 and when the olt is in its projected or operative position the recess 33 will be in a position to receive the pawl 26. Consequently, the arm, 27 or 28, as the case may be, will be moved beyond the position which it occupies when the pawl is in engagement with the teeth 24 of the bolt. This further movement of the arm places it in the path of the upper cam surface, 12 or 13, of the actuating member and it forms a positive stop to limit the movement 0f the actuating member. It will be noted, therefore, that after the bolt has been shifted to the limit of its movement in one direction the actuating device can not be again actuated in that same direction until the bolt has been moved toward the other opposite limit of its movement, thus causing the arm of the pawl to be lifted up to its normal position.
The recording mechanism which coperates with the devices here shown may be of various kinds but that which has been chosen for the purposeof illustration consists of a clock 84 having a time registering device from which a record of the time can be taken. In the present instance, this device is of a known construction and consists of a printing dial 85 from which a record may be taken showing the time at which s'uch record was taken. Cooperating with the dial to make a record therefrom is a platen 36 having a plunger or body portion 37 slidably mounted in a vertical bearing 88 and adapted to receive operative movement from the actuating device for the bolt. In the present instance, this operative movement is imparted to the platen by means of a plate 89 which is operatively connected with the platen and is held normally in its elevated position by means of springs 40. The plate 39 extends transversely of the frame and is arranged beneath and adjacent to the two actuating members 9 and 10 which are provided along their lower edges with parts, such as the antifriction rollers 41, to engage the plate and force the same downward when movement is imparted to either of the actuating members. These rollers are spaced such distances from the axes of the actuating members as will give the desired movement to the platen. The plate 39, .which is here shown as a substantially horizontal iat surfaced plate, may be of anyy shape orV character which will enable it to coperate in the desired `manner with the actuating members. The plate 39 is rigidly secured to and guided by a pin or plunger 42 which is mounted in a guideway formed in the bearing block 38 which carries the platen. The connection between the plate 39 and the platen may be of any suitable character, but, as here shown, the connection is a cushioned one and the plunger1 37 of the platen is provided with a recess in which is slidably mounted a stem 43, the upper end of which is provided with an annular groove 44 to enable the same to be inserted in a. slot 45 in the plate v39, thus forming a connection which causes the plate and the plunger 37 to move vertically in unison but permits them to be readily separated. A spring 46 is mounted in the recess to resist the downward movement of the plunger 43. This construction permits the plate 39 to Vbe moved a given distance upon each operation of the device and the cushioned. connection between the same and the platen not only gives a yielding ,pressure for taking the impression, but also accommodates the same to slight variations in distance. The record sheet or strip may be mounted in any suitable manner. In the present instance it consists of a web of paper 47 mounted on a roll 48 on one side of the platen and eX- tending about guides 49 and 50 to a receiving roll 52. Interposed between the record sheet and the form or dial is a suitable transfer device, such as the ink ribbon 53, which is wound upon spools 54 on opposite sides of the form and passes about guides 55 to position the same with relation to the form. Springs 56 pressing against the spools 54 hold the same normally against unwinding. The feeding of the ribbon may be accomplished in any suitable manner, but, as it does not require frequent adjust ment, we have, in the present instance, merely provided the spools with knurled knobs 57 by means of which the adjustment may be made by hand. Likewise, the paper feed may be accomplished in any suitable manner but it is preferable that the paper should be fed forward automatically upon cach operation of the platen and we have, therefore, provided a feeding mechanism which is actuated upon each movement of the platen. To this end the receiving roll is provided with a pinion 58 which meshes with a toothed rack 59 formed on a lever 60 pivotally mounted on that side of the platen opposite the receiving roll.' This lever 60 is connected with the platen to cause operative movement to be imparted thereto by the movement of the platen. This connection is formed, in the present instance, by providing the lever with a cam slot 6l into which projects a pin 62 carried by the plunger 42 of the plate 39. If the feed mechanism were operated throughout the movement of the platen it would, in the present machine, result in the feeding of too much paper and we have, therefore, so
may be actuated onlyv upon the movement of the lever 60 in one direction the pinion 58 is connected to the roll byy a pawl and ratchet mechanism, as shown at 63.
`We have provided means to prevent the paper feed mechanism being actuated by imparting short movements to the platen to feed all the paper off of the supply roll 48 thus lallowing the recording mechanism to be operated without making a record. To accomplish this we have provided the platen with a full stroke device which prevents the same from returning to its normal position until it has been moved downward far enough to take an impression from the form. In the present type of machine this full stroke device comprises a pawl 64 pivotally mounted on the bearing block 38 adjacent to the plunger 42 `and adapted to engage teeth 65 formed in the edge o-f the plunger. A spring 66 tends to move the nose of the pawl normally toward the teeth and the pawl is so arranged that upon the first downward movement of the platen it will engage one of the teeth and prevent the return movement of the platen. To release the platen from the pawl the latter is provided at its upper end with a finger 67 arranged to be engaged by a projection or tripping block 68 secured to the plate 39. The relative positions of these two parts are such that the pawl will betripped just as the platen completes its movement, thereby releasing the platen for return movement. To hold the pawl inV its inoperative position during the return movement of the platen and after the tripping block 68 is moved out of engagement with the finger 67 a detent 69 is provided having a squared upper end, one corner of which is adapted to be moved into and out of the path of a projection 70 at the lower end of the pawl 64. A spring 7l tends to move the detent in a direction to move this corner or nose into the path of the projection. Consequently, as soon as the pawl has been moved into its inoperative position the detent will engage the projection 70 and retain the pawl in its inoperative position during the upward movement of the platen. To release the pawl from the detent, for further operation, the platen is provided with a cam 72 so arranged that it will engage the detent and force the same out of engagement with the nose of the pawl just as the platen reaches its uppermost position. A
The actuating mechanism which is controlled from the outside of the door, that is, the actuating member l0 and the'knob 16, are normally locked against movement and can be released only by means of a key. To accomplish this suitable key-controlled devices are provided which are of such a character that they not only control the movements of the bolt actuating mechanism, but also prevent the removal of the key from the lock except when the bolt is at one limit of its movement and the actuating mechanism is in its normally locked posi tion. These key-controlled devices may be of various kinds, but those shown in the present embodiment of the invention are very efficient. As here shown the spindle 2O of the knob 16 has rigidly secured thereto a locking member which is here shown in the formvof a disk 78 having a notch 74: adapted to receive a nose 75 of a locking arm or lever 76. This lever is pivotally mounted on the frame member 2 with its nose 7 5 normally in the notch of the locking disk and is acted upon by a spring 77 tending to move the nose 75 out of the notch of the locking disk. `When the parts are in their normal positions, as shown in Fig. 3, the nose 7 5 is positively held in the notch of the locking disk, this being accomplished, by providing` the arm 76 with a projection 78 arranged to ride over the edge of a cam disk 79 which is controlled by a key. The disk 79 is adapted to be rotated by the key, and is preferably rigidly secured to a rotatable part of the lock, such as a key barrel 80. The key and key barrel may be of any suitable construction but, in the present instance, we have employed the well known Yale type of lock and key. The shape of the cam disk 79 is such that when partial rotation has been imparted to the same by means of the key the higher portion of the cam will move out of engagement with the projection of the arm 76 and will permit the arm to move under the inuence of the spring 77 to withdraw the nose 75 from the notch, thus releasing the bolt actuating device for operation from the outside of the door.
`To insure the completion of a record and of the movement of the bolt, after the initial movement has been imparted thereto, we have provided means for retaining the kej7 in the key barrel until these movements have been completed. To accomplish this the disk 79 is provided in lits periphery with a notch 8l adapted to receive the end of a finger 82 pivotally mounted on the frame l and, in the present instance, on an axis coincident with the aXis of the arm 76. The arrangement of the notch 8l and the finger 82 with relation to the cam surface of the disk is such that the finger will enter the notch when the cam surface has moved into a position to permit the releasing of the bolt-actuating device. Consequently, after the holder of a key has inserted the same in the lock and -moved it far enough to release the bolt he cannot then withdraw it until he has completed the operations necessary to release the disk 79. After the key has been oper ated to release the parts and they have assumed the position shown in Fig. 4 the knob may be turned in either direction but after it has been started in one direction its movement in that direction must be completed before it can be returned to its normal position, this being accomplished by a full stroke mechanism 83 of a well known type. The finger 82 is held in its notch by the action of a spring and, in the present instance, the spring 77 is utilized for this purpose. To this end the finger 82 has connected thereto a second finger 84 extending alongside of the arm 76 and having a pin 85 which projects through a slot 86 in the arm 76 and affords means for connecting the spring 77 with the linger 84. rThis finger 84 also has a projection 87 which rides over the periphery of a cam 88, this cam being rigidly secured to the hollow spindle 2O of the knob. In the present instance, this same cam disk 88 is utilized as a part of the full stroke mechanism 83. That portion of the cam disk 88 adjacent Vto the notch 74 is of short radius so that the spring is free to move the finger 84 about its axis to cause the finger 82 to enter the notch 8l when the key is actuated. When the knob is turned to actuate the bolt the cam disk 88 forces the arm 84 downward against the tension of the spring 77 and thus moves the finger 82 out of the notch 8l. At this time, however, the projection 78 of the arm 76 lies in front of the high portion of the cam disk 79, that is, the portion having the longer radius, as shown in Figs. 4 and 5, and inasmuch as the nose 75 of the arm bears against the periphery of the locking disk 7 3 the engagement of the cam disk with the projection 7 8 effectually holds the cam disk and, consequently, the key barrel against movement to their normal positions. However, the cam disk does have a slight movement before it comes into locking engagement with the projection of the arm and this movement is suiiicient to move the notch out of alinement with the finger 82. Therefore, after the movement of the bolt has been completed and the bolt-actuating devices are being returned to their normal positions, thus moving the .short radius 130 portion of the cam disk 88 into alinement with the projection 87 of the finger 84, the end of the finger 82 will engage the periphery of the disk 79 adjacent to the notch 81 and will, consequently, ride over the disk when the same is otherwise free for further movement. Vhen the bolt actuating devices have completed their return movement the notch 74 of the locking disk 73 will have been moved into alinement with the nose 75 of the locking arm 76 and a spring 89, acting on the arm 76 through the cam 79, will cause the nose to enter the notch, thus locking the bolt-actuating devices.` The movement imparted to the arm 76 by the cam is suiiicient to carry the projection 78 out of the path of the high portion of the cam and to permit the cam, together with the key-barrel 80, to be returned to its normal position by the spring, which is preferably connected directly to the cam. This device effectually prevents any manipulation of the bolt without imparting a full movement thereto and thus causing a record to be made and it will be noted that by the use of the two retaining devices 82 and 78 the key barrel is held against movement to its normal position until the bolt-actuating devices have been returned to their normal positions, but at the same time the key barrel is free to return to its normal position as soon as the bolt-actuating devices have reached their normal positions. The movement of the key barrel in both directions is positively limited by a stop arranged between two shoulders 91 and 92 formed on the cam disk 79.
In addition to printing the time on the record the mechanism is also adapted to print the identification of the particular key which was used to manipulate the lock. To this end the recording device has a second form 93 which is in the nature of a sliding bar arranged adjacent to the time disk and bearing type adapted to print initials, numbers or other identifying marks of the respective keys. These marks are arranged lengthwise of the type bar and are moved successively into printing position by 'the longitudinal movement of lthe bar. This movement may be imparted to the slide bar by the keys, as shown by key 102 in Fig. 2. The bar is held in its retracted position by a spring 94 and is provided with an enlarged end 95 arranged to be engaged by the keys when they are inserted in the barrel and in order that a diiferent amount of movement may be imparted to the bar by the different keys the different keys are of different lengths. Consequently, each key willmove the type bar in such a position that a different mark will be printed.
. The clock mechanism may be supported in any suitable manner but, as here shown, comprises a rectangular frame consisting of upright posts 96. Thel two posts 96 adjacent to the frame member 1 are provided with openings to receive pins 97, onto or olf of which the frame may be slipped when the casing has been removed. To retain the clock frame against accidental displacement we have provided a spring-actuated latch 98 having a nose 99 adapted to extend through an opening 100 in the frame member 1 and to engage over the edge of the frame member and thus retain the clock in position.v A finger piece 101 eXtends into a position in which it may be engaged and actuated to release the latch when it is desired to remove the clock. v
The operation of thevmechanism will be Vunderstood from the foregoing description and it will be apparent that the device is very simple in its construction and positive in its operation; that it is safe guarded against fraudulent manipulation by making it impossible to remove the key until a record has been made, or to otherwise manipulate the machine in such a way as to make a fraudulent record or to avoid making any record when the bolt is actuated. Further, it will be noted that the mechanism is all carried on the two parts of the frame and that the lock may be completely assembled at the factory. To attach the same to a door it is only necessary to provide'the latter with an opening or recess to receive the parts carried bythe frame member 1v and to permit the passage of the connecting bolts and the shaft 19. The two plates are then attached and placed in position on opposite sides of the door and again connected which completes the assembly and attaching of the lock. Neither the mechanism for actuating the bolt and the recorder or the means for preventing the removal of the key are broadly new in this application. An actuating device of this same type is disclosed and claimed inV an application for patent filed bv Bernard H. Ziehler April 25th,`1914, Ser. No. 834,518, and means for preventing the removal of the key are shown and described in an application for patent filed by Bernard H. Ziehler and James H. Dawley October 26th, 1914, Ser. No. 868,739. The present mechanisms are in the nat-ure of improvements upon the devices of these earlier applications.
