LOCK.

SPECIFICATION forming part of Letters Patent N 0. 726,254, dated April 28, 1903.

Application filed February 20,1902. Renewed March 4, 1903. Serial No. 146,233. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY GUY CARLETON, a citizen of the United States, and a resident of New York city, county and State of New York, have made certain new and useful Improvements in Locks, of which the following is a specification.

My invention relates to locks or devices used to securely fasten'doors in such a manner as to permit them to be opened by anthorized individuals only.

I provide a lock having the usual movable engaging part, a locking member therefor, a controlling device for said locking member, and two or more separate and independent means for operating said controlling device, such as a key and a combination consisting of notched wheels and levers orthe equivalent thereof. With this I combine an electrical alarm or indicator to give notice or made or is making the attempt to enter by:

v the use of the alternative meansthatis, the

combination unlocking apparatus.

My improvements include the usual arrangement of lock, key, and key-cylinder; but I add to this a second unlocking device or means for operating the controlling device, which specifically consists of a combination of two, three, or more disks and pivoted levers so arranged that the levers can only be moved when the notches in the several disks are at a predetermined point. These disks are rotatable from. the outside of the door by.

means of one or more spindlesthat is, one

. for each disk. The disks are arranged on the well-known combination-lock principle that is, in one species a thin scalloped disk is adjustably attached to each notched disk and a detaining-spring is provided for each disk, which engages with the depressions in the periphery, thus enabling the operator to determine the position of each disk of the combination with respect to an initial or vCam 15 is retracted by spring '24.

, starting point,this latter point being a smooth or uninterrupted portion of the periphery. Of course a'series of visible numbers maybe substituted for the notches and detainingspring, or both devices may be used to enable the operator to determine by both the sense of touch and of sight the position of the cooperating parts. lVith this combination unlocking device I employ an electric circuit containing an audible alarm located within the protected premises. A circuit-closer connected to said circuit closes the circuit and sounds an alarm when an unsuccessful attempt is made to operate the combination unlocking'device, but is silent when the combination unlocking device is properly set to permit the unlocking of the door.

The accompanying drawings illustrate my invention;

Figure 1 is a central section of the lock on the line C D, Fig. 2. Fig. 2 is a transverse central section on the line A B, Fig. 1. Fig. 3 shows the exterior of the lock with the keycylinder and the spindles for operating the combination unlocking device. Figs. 4, 5, 6, and 7 are details of the specific structure of the combination unlocking device.

In Fig. 1 the lock is provided with a metal frame or case 3, a face-plate 4, and astrikerplate 5. There is a movable engaging part, including the bolt 7, with the beveled striking-terminal 8, a controlling-spring 12, and a bearing 11, through which the bolt 7 slides. The beveled bolt-head 8 passes through the aperture 9 in face-plate 4 and has a back limit-stop2. The interior end of bolt 7 is provided with a head or flange 14, leaving a free section 13 of bolt 7 between its bearing 11 and flange 14. There are two operating knobs and 51. Knob 51 is on the inside of the door and controls cam 16, which engages Withflange 14 upon the end of bolt 7. Knob 50 controls cam 15, which engages with flange 14 on the opposite" side of section 13 of bolt 7. The cam 16 is retracted by spring 21. It results from this construction that knob 50 operates .cam 15 to withdraw the movable engaging part from one side of the door, while knob 51 operates cam 16 to withdraw the movable engaging part from the opposite or inner side Each knob 50 and 51 has a.

of the door.

squared spindle, which enters a squared opening in its hub 23, and each hub is integral with a cam or 16. To withdraw the movable engaging part by means of a key and keycylinder, there is a lever 17, pivoted at 19. Its lower end engages the flange 14 on the bolt. Its upper end is in position to be engaged by the cam 38 of the key-cylinder 39. This key-cylinder 39 is held in position by a traveling nut 44, having a hooked terminal 43, engaging a notch 41 in the key-cylinder 39. The position of the nut 44 is controlled by the screw 45, journaled at 46 and 47 in the lock-case 3. By turning the key in the lockcylinder the cam 38 will engage the upper end of the lever 17, causing the lower end of said lever to engage with the flange 14 and withdraw the movable engaging part against the action of the controlling-spring.

In addition to the key-operated unlocking device I provide a combination unlocking device. This consists of three hubs d cf, operated by spindles g, h, and j, accessible from the outside of the door. On the hub d is a disk 52, having a notch 53, at the bottom of which is a section of electrical insulating material 54. On the hub e is a disk 55, having a notch 56, with a section of insulating material 57 at the bottom thereof. On the hub 0 fthere is a disk 58, having a notch 59, with a section of insulating material 60 fixed in the bottom thereof. The hub 23 carries a second cam 25. The bolt 27 is provided with ahead 26, of curved contact outline, substantially as shown. The bolt 27 is provided with a groove 30, which slides over or upon the fixed pins 2.). This permits a vertical reciprocating movement. The lower terminalof bolt 27 is formed as shown at 28 and designed to enter notch 59 in disk 58. There isa lever 70, pivoted at 71, having a retracting-spring 72. Fixed upon this lever is a mechanical and electrical contact 73, insulated from the lever by a bushing 74. The point is designed to enter notch 53 in disk 52. is a lever, pivoted at 81, having a retracting-spring 82. A mechanical and electrical contact 83 is fixed to the lever 80, but is insulated therefrom by the insulatingbushing 84. The terminal 85 of lever 80 is designed to enter the notch 56 in the disk 55. The free ends of the levers 70 and 80 engage the under side of the head 26 of the sliding piece 27. IVhen the parts are in the position shown, the combination is in the unlocking position, and upon turning the spindle having the knob 50 on the outside of the door the cam 25 will rotate from right to left and riding on the curved surface of the part 26 will depress the sliding piece 27, thus causing the projections 28, 75, and 85 to enter, respectively, the notches 59, 53, and 56 and to rest upon the electrical insulating material in the bottom of said notches. The cam usual push-button 93.

push-button the alarm is sounded in the usual manner. I also provide a circuit-closer operated by the combination unlocking apparatus whenever knob 50 and hub 23 are turned while the combination unlocking apparatus is at any but the unlocking point. For this purpose I provide an insulated contact I) in the face-plate of the look. This is set in an insulating-bushing t and registers with an insulated spring-contact c in the striker-plate of the door. A branch circuit 94 is connected with the contact 0, thence to the insulated contact I), to the insulated wire 95, and to the three parallel branches, branch 96 connected to point 73, branch 97 connected to point 28, and branch 98 connected to point 83. The opposite terminal of the circuit 91 is connected by branch 99 to the striker-plate 5, thence to the lock-case 3, either by direct contact or through the bolt-head S. It results from this arrangement that if either disk 52, 55, or 58 is not in position to present the section of, insulation 54, 56, or 60 to the contact-points 75, 85, or 28 the circuit will be closed through one of the branches 96, 97, or 98 whenever the knob 50 is turned, and the movement of the cam 25 brings the described contact-points or any one of them into engagement with the uninsulated periphery of a disk.

It remains to describe the means for arbitrarily setting and shifting the combination. I call the position shown and described the unison-point of the disks. Upon each hub d c f I place a scalloped disk m n 0, respectively. Each disk 52 55 58 is provided with a fixed pin 100, and each of the disks has a series of holes 101. The scalloped disks m n 0 have a section of their periphery left smooth and unbroken. There is a detainingspring q, engaging the depression in each disk. By fixing the disk m to the disk 52 in such a manner that the notch 53 is under the contact-point 75 when the detaining-spring q is in the first peripheral depression, and by fixing the disk 0 so that the notch 59 is under the contact-point 28 when the spring (1 is in its second peripheral depression and by fixing the disk m so that the notch 56 is under the contact 85 when the spring (1 is in the third peripheral depression the unlockingknob 50 can be turned and the movable engaging part withdrawn without sounding an alarm, the combination being set with the spindles g, and h in the first, second, and third notches or positions, respectively. This position can be attained by turning the spindles till each disk presents a smooth and unbroken section of its periphery to its springq and then turning the first spindle one notch, the second spindle two notches, and the third spindle three notches, representing the combination 123. This combination may be changed or altered at pleasure by changing the location of any scalloped disk on, n, or 0 with respect to the underlying notched disk 52, 55, or 58. If the knob 50 on the outside of IIO the door should be turned and the contactpoints depressed while any one of the notches 53, 56, or 59 is out of position, the circuit would be closed and the alarm sounded, thus calling-attention to the attempt to enter.
