DOGGING NIECHNISIVI FOR TIME-LOCKS.

Specification of Letters Patent.

Patented Jan. 29, 1907.

To Car/ZZ zul/1,0771, t nur/y concern:

Be it known that I, WARREN H. TAYLOR', of Stamford, in the county of Fairiield and State of Connecticut, have invented certain new and useful Improvements in Dogging Mechanism for Time-Locks and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in .dogging mechanism for time-locks, and more particularly to improvements disclosed in application Serial No. 315,326, Iiled by me May 5, 1906.

. In the application above referred to the time mechanism is dogged and released by electrically-operated devices. Consequently it is within the power of a person who may gain access to the switch controlling the electric devices to disengage the dogging device, and consequently release the time mechanism, which latter will then at vthe completion of the balance" of whatever unexpired time it had to runoperate to unlock the doors, thus permitting access to the vault within a short time thereafter.

The object of this invention is to provide means whereby the time mechanism may be dogged by electrically-operated devices at the will of the person having control of the switch and such dogging means be released at the expiration of a predetermined number of hours or days by mechanical devices located on the vault-door adjacent to the dogging means, thus absolutely preventing any one from shortening the time at which the dogging devices will be released and the door unlocked. l

Iith these ends in view my invention consists in the parts and combination of parts and in the details of construction, as will be more fully explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation of my improved dogging device applied to the time mechanism of a lock. Fig. 2 is a view in elevation of a portion of the releasing means, and Fig. 3 is a view in plan ofthe parts shown in Fig. 2.

In Fig. 1 I have shown simply the casing for a triple time-lockmovement and a portion of the escapement-wheel of each movement; but it will be understood that a complete time mechanism, such as the well-known Yale movement, is to be used in each section of the case, and, again, while I have illustrated the triple movement the single or quadruple movements may be used. Each time-movement has as a part of its mechanism an escapement-wheel 1, suitably mounted near the top of its casing 2. Each casing 2 is provided at a point adjacent to the escapement-wheel 1 with a slot, in which the iinger 3 rests and moves. The three fingers 3 are secured to a rod 4, slidingly mounted in brackets 5, which latter may be secured to the time-lock casing or to the inner face of the vault or safe door or to any part carried by the latter.

Located adjacent to one end of the sliding bar 4 and pivotally connected to the latter by a slot-and-pin connection is a lever 6, the upper end of which is connected by slot-and-pinV connection with the sliding core 7 ofthe magnet 8.

The two ends 9 and 10 of the coil on the magnet lead, respectively, to the bindingposts 11 and 12. A conductor leads from each binding-post 11 and 12 to any suitable point-for instance, to the residence of the president or cashier of the bank and have properly included in the circuit a battery and a switch. By throwing the switch to close the circuit through the wires leading to the binding-posts 11 and 12 the current will pass through and energize the magnet 8 and move the core 7 out of the magnet, in the present instance to the right. The core 7 is provided near its outer end with a pivoted springpressed latch 13, which latter when the core reaches the limit of its outward movement engages the fixed stop 14 and detachably locks the core 7 against a reverse movement.

The outward movement of the core 7 rocks lever 6 on its pivotal bearing 15, and the lever 6, being connected to rod 4 by a slot-andpin connection, as shown, slides the rod 4 to the left until the iingers 3 engage the escapement-wheels 1 and stop the time mechanisms.

With the parts in the position last described the time mechanism is dogged by the fingers 3 and must remain so as long as the latch 13 remains in engagement with the iixed stop 14.

The mechanical means for releasing the latch 13 and disengaging the iingers 3 from l'OO the escapement-wheels 1 of the time-movement comprises an auxiliary time-movement 15, which may have a regular dial with hands, as in the ordinary timepiece, also a graduated dial 16, which makes a single revolution once in a predetermined time, and for purposes of illustration T will say seven days. This auxiliary time-movement should be wound at the same time the regular timemovements are wound, and it may be wound for the full limit-one hundred and sixty-eight hours-or for any lesser number of hours, while the other movements are wound Jfor the usual time which it is desired to have the vault locked.

The graduated dial on the auxiliary movement 15 is provided on its periphery with a projection 17, which in the revolution of the dial 16 is moved into contact with a projection 13 on the plate 19. This plate 19, which is approximately triangular in shape, is mounted on rocking shaft or bearing 20 and is provided with a lug 21, which normally rests in 'front of a lug 22 on the lever 23. This lever 23 is pivotally mounted on the stud 24 and is provided with an inwardly-extending lug 26, which is normally adjacent to the outwardly-projecting lug 25 on the plate 19. Embracing the stud 24 is a spring-wire 27, one end of which passes above the lugs 25 and 26 and the other member below said lugs. The upper end of the lever 23 is inclined, as at 23, the said inclined surface resting in contact with the shoulder 29 on latch 13 when the latter is in engagement with xed stop 14. From this it will be seen that when dial 16 has revolved to a position where the projection 17 thereon comes in contact with projection 1S on plate 19 the latter will be gradually turned on its pivot and move its lug 21 up out of the path of lug 22 on lever 23. `Until the lug 21 lpasses out of the path of lug 22 on lever 23 the latter will be prevented from moving. It will therefore be apparent that as the plate 19 is turned by the contact of projection 17 on dial 16 with projection 18 on said plate 19 and the lever 23 restrained against movement until lug 21 passes out of the path of lug 22 the spring 27, which engages lugs on the plate and lever, will be put under tension during the movement of the plate 19, the tension increasing as the plate is moved. As soon as the plate is moved sufliciently far to carry lug 21 out of the path of lug 22 the spring then acting against lug 26 throws or turns lever 23 on its pivot. This movement of the lever on its pivot forces the inclined surface thereof against the shoulder on the latch 13, thus releasing the latter and pushing the core 7 of the magnet to the left. This movement of the core slides bar 4 to the right and carries ingers 3 out of the path of the timemovement, thus permitting the latter to start up again.

With this construction it will be seen that if it becomes necessary after the door has been locked to lock it for a greater length of time than was originally intended, by making the electrical connection the movements in the time-lock proper will be stopped. If the auxiliary movement be wound for its full limit-say seven days, or one hundred and sixty-eight hours-and at the expiration of, say, ten hours the time-lock proper is dogged by the mechanism described, the auxiliary movement will still have one hundred and fifty-eight hours yet to run before it will operate to start or release the time-lock proper. After the latter has been released it will at the expiration of the unexpired time it had to run release the bolts in the well-known manner.

With this mechanism the stoppage or' the time-lock proper is accomplished at a point remote from the vault or safe and after the stoppage h as been e'l'lected it will be impossible to start up the time-lock proper, and hence release the bolts, until the time for which the auxiliary time-movement was set expires. After this operation has been performed by the auxiliary timepiece the rewinding of the same draws the plate 19 and the lever 23 back into their original position, thus leaving the core free to be again moved to its latched position.

Tt is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirt and scope of my invention. Hence I would have it understood that- I do not wish to confine myself to the exact construction of parts shown and described; but,

Having fully described my invention, Wh at T claim as new, and desire to secure by Letters Patent, is-
