SPECIFICATION forming part of Letters Patent No. 456,182, dated July 21, 1891. Application flledApril 9,1891. Serial No. 388,293. (No model.)

T0 @ZZ w/tom it may concern.-

Be it known that I, ABRAHAM S. WILEY, a citizen of the United States, residing lat Detroit, county of Vayne, State of lvlichigan, have invented a certain new and useful Improvement in Safes or Vaults; and I 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 pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

In the drawings, Figure 1 is a front elevation upon the interior of a safe or vault door, illustrating my improved door-locking mechanism. Fig. 2 is a side elevation of the same. Fig. 3 is a separate view of one of the solenoid-rods made of alternate sections of mag- In the construction of burglar-proof doors for safes and vaults it has been the custom to provide an arbor with which to operate the bolt-work, the said bolt-work being located on the inside of the door and the arbor projecting through the door. It hasalso been customary to place a lock upon the inside of the door, actuated by another arbor passing through the door. Thus the door has been pierced by two or more round holes through which the arbors have passed. Many successful attempts have been made to burglarize such doors by drilling' the arbors, by forcing them out, or by introducing explosives through the space around them, and having succeeded in introducing a sufficient quantity of explosive to the interior of the safe its doors have been burst open.

I. have in View to provide adequate means of throwing the bolts of a door into the locked position and to subsequently retract these bolts by the employment of electro-magnets back of the door, either fastened upon the inside of the said door or upon any suitable support independent of the said door, which shall be actuated by an electric current conveyed through the spools of said magnets, thereby wholly obviating the evils associated with the use of arbors projecting through the door, the door being wholly without holes of any character leading through it. Then, again, since a burglar might direct an electric current through the said magnetic circuits it becomes necessary to include within the system mechanism such as a time-lock or similar appliance and a dog for doggingthe bolts in their locked position against an unlocking motion until at a predetermined hour the said dog may be released or be brought into a condition to be released by the operator upon the outside of the safe.

My invention therefore consists, essentially, first, in providing the door with one or more locking-bolts and one or more electro-magnets located either on or behind the door and adapted when the circuit is closed through them to throw the said bolts into their bolted 0r unbolted position, and in connection therewith a separate dog adapted to prevent the unbolting movement of the bolts, and means for disengaging said dog prior to the unlocking movement of the bolts; second, in connection with the foregoing a time mechanism adapted to control the disengagement of said dog, whereby the dog is or may be disengaged at a predetermined time; also, in special features of construction, which will be hereinafter specified and claimed. n

In carrying out my invention, A represents a'safe or vault, and B its door. y

C represents a series o f bolts, which in the instance shown are Vin the nature of rotary bolts or buttons.

D represents bars having projections d, which work in corresponding orifices d in the bolts C, so that by the longitudinal movement of the bar D all the bolts connected therewith n will be simultaneously actuated.

E represents a cross-bar pivoted at e and engaged at the extremities with the bars D, so that'through this pivoted barlilany movement of either of the bars D is necessarily communicated to the other, and all the bolts are thereby caused to act in unison.

F F represent series of electric coils or helices. j" and f2 represent common shafts extending along the axes of the said helices, respectively. Each shaft is made up of magnetic sections fwithinterposed diamagnetic sections f4, Thus the sections f3 may be of soft iron, and the sectionsf may be of brass, thus constituting a series of solenoids with a continuous or connected series of cores. d2

ICO

represents arms projected out from the bars E', which projects from the level1 E.

whereby any movement of the cores of the solenoids is communicated directl y to the said bars D, and through them to the bolts C.

The operation of this portion of the mechanism will now be understood. We will presume the solenoids I1" on the right-hand side of the door tobe all connected into a circuit, the terminals of which are at the exterior of the safe, and those at the left-hand side of the door at F connected in like manner with another circuit, the terminals of which are also on the exterior of the door. It is appar-n ent that by sending a current of electricity through the last-named circuit the left-hand solenoids opera-te to force upwardly the coreshaft f', and this serves to simultaneously throw all the bolts into their unbolted condition, permitting the door to be opened. It also serves at the same time through the bar E to drop the solenoid-shaftf2 of the right hand helices into their lowerrnost positions out of their respective cores, so that by subsequently disconnecting the current from the solenoids F and sending an electric current through the said last-named helices F this core-shaft is forced upwardly and the bolts are all again thrown into their bolted position.`

Ihile the arrangement of solenoids as shown is convenient and desirable, I would have it understood that any suitable arrangement of electro-magnets, whether in the form` of solenoids or ordinary armature-magnets, might be employed, and instead of the rotary bolts any other suitable arrangement of bolts might be used.` These solenoids might be grouped into several circuits, and each group be provided with exterior terminals, so` that if any particular circuit is deranged the others may suffice to actuate the bolts. I show the left-hand magnets arranged in groups of three and the right-hand magnets also in groups of three, their admission terminals being represented at f5, and a common returncircuit f for all of them. Of course' this may be varied to suit the circumstances.

H represents-a time-lock of any usual type,` so organized that at apredetermined time its hook I-I might be withdrawn from the lever Il2 and permit the same to drop.

I-IJ is a dog suspended from the lever 112, so that when this dog is raised up and held by the hook I-I the dog will be interposed between the stationary block HL and the arm It is manifest that when the dog is in this position the bolts cannot be moved into their unbolted position, and that this dog will remain in place until the latch or hook II is tripped by the timelock mechanism at a predetermined hour. Then the bolts thereafter are moved into their unbolted position and it is desired to lock the door, the following construction is provided:

71, is an independent lever held contiguous to the lever H2 by a spring located between them and adapted when either leverisraised or lowered to spring the other lever to a contiguous position to the one moved. rlhis permits the lever 7L to be raised and engaged with the hook Il prior to closing the door. Then when the bolts are thrown into their locked or bolted position the movement serves to open the space between the block Il and the arm E', and as soon as the space is sutlicient the spring lifts the lever H2 up contiguous to the lever 7L, where it remains until the time-lock disengages the hook and permits both levers to drop down together, as before described.

I do not of course limit myself strictly to a time-lock which shall operate to drop the dog out of place, but the timeloek might serve simply to leave the apparatus in shape, so that by any provided means the dog might be subsequently removed from. its place.

I am aware that an electro-magnet` has been employed to unlatch or unbolt a door,but am not aware that such mechanism has ever before been made to bolt or unbolt a `doorin combination with a dog for blocking or prc venting an unlocking movement of the bolts until the said dog was released by a time-lock or other means.

Vhat I claim isl. In a safe or vault, the combination, with one or more locking-bolts, of- `oneor `more electro-magnets adapted when the electric circuit is closed through the same to move said bolts into or out from their locked or bolted position, and a dog adapted to prevent the `unbolting movement of the bolts, and `mea-ns adapted to disengage said dog priorlto `unbolting the door, substantially as described.

2. In a safe or vault, the combinatiomwith one or more locking-bolts, of one ormore electro-magnets adapted when the electric current is closed through the same to move said bolts into or out from their locked or bolted position, a dog adapted to dog said bolts against an unbolting movement, and a time mechanism adapted to withdraw or permit the withdrawal of said dog at a predetermined time, substantially as described.

3. The combination, with a safe or vault door, of one or more locking-bolts and one or more electrosmagnets in the form of solenoids, the cores of said solenoids engaged with the bolt-throwing mechanism, whereby they may serve to throw the bolts into their bolted or uubolted position, substantially as described.

l. The combination, with a safe or vault door, of one or more locking-bolts and a series of solenoids adapted to actuate said bolts, said solenoids arranged inline with each other and having a connected series of cores, substantially as and for the purposes described.

5. The combination, witha safe or 1vault door, of one ormore loekingbolts and a series of solenoids adapted to actuate said bolts, said solenoids arranged in line with each other and provided with a common core-shaft composed of alternate core-sections of magnetic mate- TOC IIO

6. The combination, with a safe or vault door, of a series of rotary bolts C and a series of solenoids F, said solenoids each engaged by common connecting-bars with the said bolts, whereby the motion of the core of any solenoid is communicated to each and all said bolts, substantially as described.

7. The combination, with a safe or vault door, of a series of bolts engaged by connecting-bars D and E, and two series of solenoids, one adaptedby the inward movement of its cores to throw the bolts into their looked the rst solenoids to their initial position, subzo stantially as and for the purposes described.
