SAFE OR VAULT LOCK.v

SPECIFICATION forming part of Letters Patent No. 427,140, dated May 6, 1890. Application tiled January 16, 1888. Serial No. 260,838. (No model.)

To all whom it may con/cern.-

Be it known that 1, CHARLES O. YALE, a citizen of the United States, residing in the city of Rome, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Safe or 'Vault Locks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the iigures of reference marked thereon, which form part of this specification.

My invention relates to an improvement in safe or Vault locks.

Itis the object of my invention to provide a safe-door without a hole through the plates thereof and a lock for locking and unlocking l the Y door or any door to which it is adapted or applied.

In the drawings similar numerals of reference refer to like or similar parts in the several figures.

Figure 1 shows a section of a safe on a line substantially with the inner face of the door and my locking device mounted thereon, some of the similar parts there-oi` being removed or left out of the drawings. Fig. 2 shows an end view of a beveled gear-wheel and its shaft for rotating the bolt. Fig. 3 is a sectional view of an actuating-case, and shows a ratchetwheel and dogs -for actuating the locking device. Fig. 4 is a detail view, partially in section, showing the actuating device and its connection with gear-wheel and rack for operating the bolt-work. Fig. 5 is a view of the side of the actuating-case nearest the boltwork, and shows a slide, pin, and lugs for adjusting or operating the dogs tothe ratchetwheel. Fig. 6 shows a rack for rotating the bolts and engaged in a pin-wheel on the bolt for rotating the same. Fig. 7 shows a brokenout section of a section of the safe, taken on a line with A B, Fig. 8, and shows a bar carrying a portion of my locking device upon the inner face of the door. Fig. 8 shows a longitudinal cross-section of a safe-door and its jamb substantially on a line with C D of Fig. 1, and a device for moving the door and a part ofthe bolt-work of my locking device contained inside of the door. Fig. 9 is a detail View showing device for communicating rotary motion from one bolt to the other at yright angles thereto.

Heretotore bolts have been moved into position with the door for locking and then the bolts thrown. It is one of the objects of my invention to compound these two moveme'nts.

I provide in my locking device one or more bolts having a compound movement. Upon the inner surface of the door 1 is mounted a number of bolts 2 2, 3 3, and 4 4. These bolts operate through a bar 5, secured to the inner face of the door, and are adapted to be thrown or projected back of the inside of the plates 6, which plates may be a portion of the body of the safe. and drawing the bolts I provide a throw-bar 7, to which bar are secured bolts 2 in such manner as to be thrown and drawn by and with the bar, but admit of their being rotated. The bolts 8 are secured to bar 8, and are thrown and drawn by the movement of the bar 8, which movement is accomplished simultaneously with the movem entof the other bolts by means of rack 9 on an arm of bar 7 and the rack on arm 10 of bar 8 and pinion 11, pivoted to the door and engaging in each of the racks.

Bolts 4 are drawn and thrown by means of lever 12, pivoted to the door at 13. One end of lever 12 is forked and adapted to engage bolt 4 in a groove 14, so as to throw and draw the same without interfering with the rotation thereof. The opposite end of lever 12 from that which engages bolt 4 is provided with a slot 15. Pin 16:L of throw-bar 7 is adapted to move in the slot 15 and actuate lever 12 as the throw-bar 7 is thrown and drawn, and thus simultaneously thro-w and draw bolts 4 with the other bolts.

For rotating the bolts or so many of them as it is desirable to rotate, means are provided. Bolts 2 are provided with pin-wheel 16, Figs. 1 and 6, secured to the bolt and adapted to be engaged by movable racks 17, which racks are on movable bar 18, Fig. 1. For rotating bolts .4, I provide bevel gears 19 19, Figs. 1, 2, and 9, which gears engage each other and are mounted on shafts 2O 20. Shafts 2O are mounted in bearings 21 and pass into proper holes in the end of bolts 2 and 4, and have the ends slotted, as shown in For throwing ICO . or drawn.

Means are provided for allowing a movement of the door while the bolts are being thrown or drawn. As a means of allowingof this movement, I provide in the outer ends of each of the bolts 2 and 4 and all of the bolts of the door, if desirable, recesses 23 and 24, Figs. 6 and 7. Recesses'23 and 24 in the ends of the several bolts are adapted to receive raised projection or fence 25 of plate 6, Figs. 1 and 8, or so many thereof as are designed to receive the rotating bolts.

For the purpose of throwing and drawing the several bolts for securing the door I provide the following means: Thepinion 2li, Fig. 4, pxvoted to the door, meshes into rack 27 on throw-bar 7 and is adapted to move the same. Pinion 26 is provided with beveled gear-teeth adapted to engage beveled gearwheel 28 on a shaft 29, which shaft rotates in a bearing in bar 5. On the opposite' end of shaft 29 from gear 28 is mounted ratchetwheel 30, Figs. 3, 4, and 5. Ratchet-wheel 30 1s adapted to be engaged by either dog 31 or dog 32. Dogs 31 and 32 are pivoted at 33 and 34, respectively, in a movable case or frame 35, Figs. 3 and 5, and are provided with slotted arms, as shown at 3G, Fig. 3. The dog and arm are adjustable with reference to each other, but are held substantially in the relative position shown in Fig. 3 by spring 37. Spring 37 is intended to allow the dogs to pass the teeth ofthe ratchet-wheel 30 during the retrograde Vmovement of the ratchet-wheel. Dog 31 is thrown out of and dog 32 into contact with ratchet-wheel 30 by moving vertically pin 38, which passes through the slot inv each of the arms of dogs 31 and 32 so far as the slotin case 35, through which the pin 38 passes, will permit; or both dogs may be thrown out of engagement with the ratchet-wheel by moving the pin half-way. Pin 38 is secured in and moves with plate 39, Fig. 5, the pin passing along slot 40 in case 35. Plate 39 moves in ways or guides 41 41, and is provided with ears or lugs 42 42 for the reception of the end of lever 43, Fig. 1, between them. Lever 4 3 is pivoted to the door at 44, and is provided on the under side with a projection 45, (shown in dotted lines,) adapted to come in contact with projection 4G on throw-bar 7, (alsoshown in dotted lines in Fig. 1,) which projections while in contact are adapted to hold lever 43 in its upper or lower position. The end of the lever 43, which is adapted to be engaged between lugs42, Figs. 1, 4, and 5, is broad enough to allow of the movement of the case 35, hereinafter described, without.

the lever or lugs being disengaged from each other. Case 35 fits movably in a recess in bar 5, and is held in its normal position by 'projection is provided at 62.

springs 47, Fig. 7. Case 35 is provided with lugs 48 48, Fig. 5, which lugs are adapted to be engaged by lugs 49 49, Fig'. 1, on plate 50 when the door is closed or nearly so, which plate is secured in proper position on the body of the safe. 51 is an ordinary time-lock, which is adapted to operate tripper 52, which tripper operates catch 53. Catch 53 is adapted to engage lever 54 by shoulder 55 thereon, resting upon shoulder 56 of the catch. Lever 54 is pivoted at 44 to the door. The opposite end of lever 54 from that engaged by catch 53 is provided with a slot or opening 57 for the reception of projection 58 upon verticallymovable bar 18. Lever 54 and bar 18 vare raised or held up by spring 59, secured to the door at 60 and to the lever at 61.

Upon the under side of the bar 1 8 a lug or This lug is adapted to engage projection 63 on the inner face of the door and pass along the upper side of the same, down the right-hand end, along the other side, and up the left-hand end, passing entirely around projection 63 every time the door is locked and unlocked. Projection 63 is secured to the inner face of the door and projects through slot or opening in throw-bar 7 to such adistance that it may be engaged by projection 62 on the under side of bar 18. Bar 18 is held to throw-bar 7 by y guide or clasps 64 G4 in such manner as to move with throw-bar 7, but ad mit of a verticalmovement independent thereof. For moving the door out to allow'of the tongue and grooved jamb being disengaged from the tongue and grooved door, and to provide for the slight inward and outward movement for operating my locking device, I provide a vibra-ting hinge, as shown in Fig. 8. 65 isa vertical shaft made to vibrate, which has fixed to it crank X. At 66 is a hole in the crank to admit the pintle 67, which rotates therein, the pintle being secured to ear 68, which is fastened to the door. 69 is a lever-handle for partially rotating shaft 65 and producing an inward and outward movement of the door through the crank X. Ear 70 hinges shaft 65 to the body of the safe. Handle 69 will swing' around pin 71 out of the way of the door while open.

Gears 19,I prefer to provide with a cut-away portion, as shown in Fig. 2, so as to admit of their being more readily placed in position in the locking device.

The operation of my locking device is as follows: Starting with the lock, as shown in Fig. 1, in which position it is partially unlocked, I take handle G9 and draw it out from the safe. This moves the edge of the door neXt to the hinges out of the jamb slightly, as shown in dotted lines in Fig. 8, the fence 25 on the plate 6 passing into the recesses 24 in the ends of the safe-bolts. During this outward movement or vibration of the door just described projecting lugs 48 of case 35 are held in contact with projections 49 on the jamb by the springs 47 acting between IOO IIO

the case 35 and the door. The case is thus held stationary with reference to the jamb while the door makes the slight outward movement or vibration just described. The dogs or pawls 31 and 32 being pivoted in the case 35 and the dog 31 in contact with rack or ratchet-wheel 30 during the process of unlocking, and the ratchet-wheel 30 moving through the door, and the casing in which the dog 31 is pivoted being stationary, the dog 31 will be retracted over the ratchet-face of the wheel in the outward movement or vibration of the door, and will engage a succeeding tooth in the ratchet-wheel 30 when the door has reached the limit of its outward movement by the bottom of recess 24 coming in contact with the top of fence 25. Handle 69 is then forced back toward the door, which lnovement forces the door back into the jambs, and the lugs 49, engaging lugs 48 of the case 35, prevent it passing inward with the door; but the ratchet-wheel engaged by dog 31 must lnove positively with the door, so that as the door is forced inward the ratchetwheel 30 is rotated. This rotates gear 28, pinion 26, and moves rack 27, carrying the throwbar 7 backward and drawing or partially drawing bolts 2. At the same time bolts 4 are drawn a like distance by pin 16a on throwbar 7 acting on the inclined face of opening in the lever 12 and carrying the bolts 4 back, and bolts 3 are drawnv by the action of rack 9 and rack on arm 10 and pinion 11, as hereinbefore set forth. -As the door passes into the jamb from its outward limit of vibratory movement to its inner movement the springs 47 between the movable casing 35 and the door are extended or stretched. The inward and outward movement of the door is continued, the dog gaining on the ratchetwheel with each outward movement until it has been sufficiently rotated by each inward movement to draw the bolts so that they will pass plate 6 and allow the door to be fully opened. Vhen the door is unlocked, projection 46 has passed to the right far enough to allow projection 45 of lever 43 to be passed upward byit, and projection 62 on the under side of bar 18 has passed to the right far enough to allow it to be passed down the right-hand end of projection 63.

W'hen it is desired to lock the safe, the timelock is set and lever 43 is passed up, so that projection 46 will pass along the lower side of projection 45 and hold lever 43 in its upper position. Bar 18 is drawn down by the operator moving the same with his hand while the door is open until projection 62 will pass under projection 63. The raising of lever 43 throws dog 31 out of contact and dog 32 into contact with the ratchet-wheel 30. The drawing down of bar 18 rotates all the bolts that are designed to be rotated through the mechanism hereinbefore described, so that the recesses 23 in the bolts will coincide with the fence on the plate 6 when the door is closed. The downward movement of the bar 18 also raises shoulder 55 up to and above shoulder 56. The door having been swung into position for locking,handle 69 is moved in toward the door. This passes the door into the jamb and the lugs 49 on plate 50 come in contact with lugs 48 on the movable case 35 and limit the further inward movement; but the casebeing sli ghtlyin advance of the door by reason of the springs 47 become stationary with reference to the jamb before the door has swung completely into the jambs, and the door continues its inward movement after the casing 35 has become stationary with reference to the j amb. The ratchet-wheel is carried against dog 32, which produces a slight rotation thereol',

which rotation is communicated to the bolts,as

hereinbefore set forth, onlyin a reverse direction from the motion of the same parts hereinbefore described. After the door has been passed entirely into the jamb,the first time, the bolts will be thrown so that they will not pass the plate 6. Handle 69 is then drawn out, moving the door out of the jamb until its movement is limited by the top of the fence 25 coming in contact with thebottom of the recesses 23 in the bolts. During the outward movement of the door the case 35, with the dogs, is held back against lugs 49 by springs 47. While the ratchet-wheel is carried out with the door, the door being again forced back into the jamb, another slight rotation of the ratchet-wheel is produced and the bolts thrownfarther out. This operation is continued until the bolts are fully thrown, at which time lug` 62 has passed entirely along and beyond the lower side of projection 63. As soon as lug 62 has passed Vby the end of projection 63 bar 18 is drawn upward bythe action of the spring 59 until lug 62 is stopped directly opposite the leftfhand end-of projection 63. The upward movement of bar 18 is stopped, as indicated, by shoulder coming in contact with shoulder 56. As the bar 18 is moved upward by the action of the spring 59 the bolts 2 and 4 are rotated, and as the upward movement of the bar is stopped by the catch 53 engaging the lever 54 the parts are so arranged that the part 72 of the bolts will rest upon the top of the fence 25, and in this position movement ofl the door is prevented. At the time whenv the bolts have been entirely thrown projection 46 has passed entirely along the lower side of projection 45 and beyond the lefthand end thereof, and lever 43 has descended, throwing dog 32 out of contact and dog 31 into contact with ratchet-wheel 30, in which position the parts are ready for the unlocking process, as shown in Fig. 3. In these several positions the several parts remain until the time-lock 51 has moved tripper 52 and thrown catch 53 out of engagement with lever 54. Spring 59 then causes bar 18 to complete its upward movement, rotating the bolts until recesses 24 ofthe several bolts register with and are in a position to receive fence 25, in which position there may be a slight vibra- IOO IIO

tory movement of the door, which movement will unlock the door, as hereinbefore set forth.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a door, a jamb, a bolt for locking the door in the jamb, having a recessed or cut-away portion of the projected ends adapted to admit of a vibratory movement of the door when the bolt is thrown, and the connecting mechanism between the jamb and the bolt, whereby the bolt may be thrown and drawn by the vibratory motion of the door.

2. The combination of a door, a jamb, a bolt for locking the door in the jamb and constructed and arranged to admit of a vibratory movement of the door when the bolt is thrown, connecting mechanism or gear ing between the jamb and bolt for throwing and drawing the bolt by vibratory movement of the door, and time mechanism and a catch for securing the bolt in certain fixed position.

'3. The co1nbinatiou,with the door and j amb, of a bolt for locking the door in the jamb and the connecting mechanism for throwing and drawing the bolts by the vibration of the door, substantially as set forth.
