l- Claims.

This invention relates to a control system and apparatus for protecting currency and valuables in banks or other institutions.

In the bank protecting devices of the prior art, it has been the general principle ofoperation to create an alarm upon a holdup, so to summon the police and to warn the entire region surrounding the scene of the holdup. Such devices, while helpful, nevertheless permit access to funds and valuables and make it possible for highwaymen to reach those funds, after which escapes are frequently possible. It is the object of our invention to devise a system which will primarily prevent access to funds, this system being of the type disclosed in the basic application on this subject filed by William Goehring, Serial No. 419,652, and further applied to a drawer locking system by George W. Singleton; in application Serial No. 419,590.

In the application of Goehring, there is maintained a group of locks which are normally operative, but which, upon an attack on the bank at any particular place, or upon destruction of any of the circuits which are protected by balanced relays, are individually rendered inoperative so that they can no longer be operated by the usual means. This control functions to maintain the locks inoperative until a definite period, which is arbitrarily set, has elapsed,

whereupon the system will once again reestablish itself. One of the features of the Goehring invention in its preferred embodiment, is that the time controlled reset mechanism is itself maintained under supervision of a lock which is part 0f the general protected lock system. Another,

is that the system is reestablished under time control. The system which we are disclosing herein is dominated by claims in the Goehring application, but shows a variation over the Goehring structure whereby to eliminate one of the expensive features of Goehring, that is, the

reestablishment of the system by time control.

At the same time, however, this invention utilizes the Goehring broad principle of locks rendered inoperative and adapted to be reestablished by means which are themselves under time control.

Specifically, our invention includes a safemechanism having locking drawer, a combi- 50 nation locked chest, and a chest which is under time control of the type exercised by a delayed time mechanism shown in the Miller Patent Cal . 1,858,964 owned by the assignee of this applica,

tion. The locking drawer and the regular com- 55 bination lock of the chest are under the type of I particular control of the-drawermechanism, the T time control disclosed in the Goehringapplication as will be specifically indicated in this application later, there being an electric circuit which upon the disturbance of any. portion thereof, or upon the closing of a pushbutton circuit, will cause the drawer and lockto be rendered inoperative. In order to reestablish the circuit and render the drawer and lock operative again, a control for reestablishing the circuit is-located in the chest which is controlled by 10 the delayed time lock device. Therefore, once there isa lockout created, it is necessary to set the delayed time mechanism, the operation of which is described by Miller in his patent, whereupon the time -mechanism will run a definite -15 period to permit subsequent opening of the chest whereby to reach the central control mechanism. Naturally, while. the drawer, combination locked chest, and-time controlled chestare all shown in one structure herein, theymay just as well be in 20 separate structures.

.Other objects and features of our invention 'will appear from the description which follows, .but the more important features relate to the means for deadlockingand maintaining control over the combination lock chest, and the general circuits for-controlling the entire arrangement.

For a further description of our invention, we shall now refer tothe drawinga wherein Fig. 1 30 is a view of a safe embodying my invention while Fig. 2 isa View of the same structure showing the combination locked compartment andthe time lock compartment opened.

Referring now to Figs. 1 and 2, reference numeral it! represents a preferred embodiment of a safe structure in which our invention is incorporated. This safe structure has a lower compartment H, a middle compartment 52, and an upper drawer compartment i3. It is intended in the ordinary operation of the safe structure, if located in a bank, that the upper drawer compartment l3 shall carry the relatively small amount of money which is necessary for ordinary change. The middle compartment I2 is adapted to carry a reserve amount of currency which is available as soon as the combination lock mechanism is is operated by a dial is and the bolts It retracted by the handle ll. The main amount of currency is to be maintained in the compartment H and is only accessible after the combination dial mechanism is set as by the dial l8, and the bolts 18 withdrawn partially by the handle member 2Q to start the delayed time lock mechanism 2i as is illustrated more particularly in the Miller patent indicated supra. Once the mechanism 2! is started running as taught by Miller, it is only necessary to wait the delayed period for which the time look was set, after which the bolts may be withdrawn fully and the compartment ll rendered accessible.

It is intended in the general operation of our invention, that the drawer l3 be electrically controlled so that upon the depression of the push button 22 it will be possible to move the drawer to an outward position in which it will be allowed to remain. Immediately upon an attack on the bank, the operation of strategically located push buttons, or the upsetting of balanced circuits, etc. will operate controls so that the drawer 53 will be allowed to move to a fully closed position from which position it will be impossible to disturb it until the circuit through the electrial control mechanism of the drawer I3 is restored in a manner which will be set forth later.

The reserve currency which is maintained in the compartment I2 is ordinarily accessible onl by the operation of the bolts it after setting of the combination mechanism M by the dial l5. However, there are located electrical mechanisms, which may be of several types, for preventing the operation of the dial lock i5 in the usual. way to retract the bolts IE, immediately upon the disturbance of protection circuits by push buttons or balanced circuits throughout the banking room in the same manner as the circuit through the drawer i3 is disturbed.

In the preferred embodiment of our invention, the compartment H is adapted to contain the greater amount of currency carried by the bank or other institution. This compartment is maintained locked by the bolts l3 which are retractable by the handle 2!) upon the setting of the combination by the dial l8 and controlled by the delayed time locking mechanism 2!. This mechanism is of the type shown in the Miller patent as explained above, in which it is possible to set the time mechanism so that it will operate after 15, 30, or any other number of minutes, to permit the opening of the safe structure, after an initial operation has been carried out. Therefore, should the custodian of the safe mechanism be forced to set the dial mechanism, the robbers will know quite definitely that it will be impossible to reach the funds in the main structure ll until the delayed time mechanism has run down. It will be obvious to them that this wait is essential since the fact that the safe is so controlled is to be advertised outside the bank and by conspicuous signs on the safe structure. It will be quite apparent to those skilled in the art that few robbers will be willing to wait 15 or 20 or 30 minutes until the safe structure is open, especially, if incidental to the operation of the locking mechanism for the safe, there is a vigilante or alarm operation.

The invention embodies further the placing of a reset mechanism 23 in the compartment ll which reset mechanism controls the electrical circuits which prevent the operation of the drawer it, or the opening of the door of the compartment 52. The reason for locating this mechanism in the chest l l is to insure that once the circuits through the drawer l3 and through the control of the compartment l2 are broken and access to compartment l2 and the drawer i3 is impossible, that it will be necessary to set up the delayed time lock mechanism 2! and allow the delayed time period to run before the mechanism 23 may be reset to permit access to the compartments l2 and it. This renders the compartments i2 and I3 robber-resisting since their opening is impossible except after the delayed period of mechanism 2i, once an alarm is sent out.

We have now described rather specifically the operation of the devices of Figs. 1 and 2 from a functional viewpoint. We will now indicate more particularly the structural means by which the invention is carried out, although we wish it understood that the general purposes of the invention as set forth with relation to Figs. 1 and 2 may be accomplished by other mechanisms operating on the principle of the mechanisms particularly disclosed herein, and that'we feel ourselves entitled to patent claims which will dominate such mechanisms.

Referring now more particularly to Figs. 2, l, 5 and 6, we show detent mechanism for controlling the operation of the bolts of the door preventing access to the compartment There are mounted on the side surfaces N of the compartment it a pair of buttress members 25 and 26 which are equipped with portions 27 and 28 for the admission of the upper and lower bolts to for the purpose of re-enforcing those bolts in their locking position and for providing a substantial bearing. Behind the surface 24-, there is located a plate 29 to which is secured the control mechanism for the bolts it. This con trol mechanism includes an electro-magnet 823 having an armature 33 to which is secured a dogging slide 32 mounted slidable on screw threaded studs 33 protruding from the block member 3 5.

Mounted also onthe plate 29 are a pair of switch blade members 35 and 3S insulated from each other and controlled by a spring pressed member 3'! which is normally pressed forward in a position to maintain the members 35 and 3S separated as shown in Fig. l. The cooperative operation of this apparatus will now be explained, but its operation electrically relatively to the entire system will be more specifically shown with reference to Fig. 3 later in this specification. It is intended that the electrical control circuit traversing the electro-magnet 30 shall include the switch blades 35 and 36 so that it is necessary, in order to complete the circuit through the electro-magnet St, for the switch members 35 and 36 to be in contact relation as is best shown in Fig. 6. Naturally, the circuit through magnet 36 includes the outside circuit which is control-led by the reset mechanism 23 in the compartment H, and which, when in a particular condition, will prevent the closin of a circuit through the relay Bil regardless of the position of the switch members 35 and 3%. This will prevent the necessary operation of relay Si] as required to obtain access to compartment it.

As will be quite obvious, should the outside circuit be closed, then retractive movement of the bolts it will first cause the upper bolt it? to contact the spring member 37! to permit switch members 36 and 35 to move into a closed position. This will immediately close fully the circuit through the electro-magnet 3ilwhich will draw the detent member 32 from its position of Fig. 4 to its upper position illustrated in Fig. 6 to permit the lower of the bolts Hi to move into its fully open position of Fig. 6, which movement will be shared by the other two of the bolts it as will be quite apparent to those skilled in the art. Access to the compartment i2 is then possible.

We shall now describe the mechanism which controls the operation of the drawer it. This mechanism is substantially the same in principle of operation as that of the control mechanism of Figs. 4, 5 and 6 and is best illustrated in Figs. 7 to 18 inclusive. Referring now especially to Figs. 7 to 9 inclusive, the drawer It has secured to its back plate 5% a regulation liquid checking spring door closer lil which through its arms 52 and 53 exerts continuous pressure tending to move the drawer i3 into its closed position illustrated in Fig. 7. Upon movement of the drawer to its open position of Fig. 8, the closer will be maintained under tension and adapted to move the drawer to a closed position immediately upon the release of the drawer as will be fully described presently.

For maintaim'ng the drawer in its locked position, and in its open position, and for permitting its movement to open and closed positions, the drawer is equipped with a spring pressed locking tumbler and a triangular locking cam 55 which are in turn cooperable with the armature controlled detent 55 shown best in Figs. 12 to 18 inclusive. This detent member 56 is pivotally mounted on a screw stud El and has a dogging portion 58 pivoted at 58 at one of its ends to the armature Bil of the control relay 5!. This control relay iii has external and internal circuits similar to those described in connection with the electro-magnet 3a of Figs. l, 5 and 6. The relay 5! has an internal circuit comprising the push button 22 and the mercury switch plate 62 which is operated and controlled by the extension 63 secured to the drawer it for integral movement therewith. The mercury switch plate 62 has the independent mercury tubes 6% and t5, the operation of which will be more fully described with regard to the electrical control as set forth in Fig. 3.

We will now describe the mechanical operation or" the mechanism of Figs. 7 and 8 in'detail, with reference to the pawl and locking members 54 and 55 and the detent 56 as controlled by the armature Bil of the relay ti.

Figs. 12, 13, 14 and 15 illustrate more particularly the cooperation of the dog portion 58 of member 56 with the locking cam member in the position of the locking drawer illustrated in- Figs. 7 and 10. As is shown in Fig. 12, when the armature til is in its upward position, which is the position it will occupy when the circuit is at the time that its external control circuit is also closed, the armature it and dogging portion 58 will be moved downward into the position of Fig. 13 so that the cam member 55 may be moved to the right with the drawer IE to the open drawer position illustrated in Fig. 8.

In the position of the drawer in Fig. 3, the

relationship of the holding tumbler member 54 relatively to the dog at is best shown in Figs. 16 to 18 inclusive. As will be quite obvious from Fig. 16, as the drawer moves to an open position with the electro-magnet actuated, as is necessary in order to release the drawer for open movement, the tumbler 5t will be moved downwardly under the dog member 58 against the pressure of its spring 6%, and upon reaching the position of Fig. 16 it will jump up into the position illustrated with its end surface l5! solidly against the surface of the dog member 5%.. In this position,

and as long as the electro-magnet 6! is maintained actuated by the closing of its internal. and external circuits, the drawer it will beheld in its open position of Fig. 8. Should the circuit through the electro-rnagnet 5! be broken, either in its external control circuit in which the mechanism 23 located in compartment H is a controlling factor, or in its internal circuit, then the armature Elli. will move to its upward position of Fig. 17 whereupon the holding tumbleri l' will pass under the dog 5& and permit the drawer to move to its fully closed and locked position of Figs. '7 and. 12.

The internal circuit of the drawer control magnet El includes the push button'ZZ shown mechanically to Figs. 1 and 2, and the mercury tubes is and which are controlled by the member 62 secured to the drawer 53. Referring to Figs. 10, 11 and 15, it will be seen that when. the drawer is in a fully closed position, the mercury tubes will be inclined in the position best) illustrated in Fig. 3, wherein the circuit will be closed through the contacts. of the tube 64. However, when the drawer is open, the circuit is then closed through the mercury tube 65. The member 82 is weighted as at 59 so that it will assume the position of Fig. 11 quite readily when released by the outward movement of the rod member 63 of the drawer l3.

The mechanical construction of our control cabinet 23 located in the compartment ii is best illustrated in Figs. 19 and 20. It includes a series of resistance members '58, ll and 72 which are variable in type, and electro-magnet H which is the main magnet of my control system. This magnet l3 has an armature M which carries the pair of switch members it and Ti coop-erable with switch posts it and is respectively for a purpose which will be described hereinafter. The spring 15 normally maintains the armature i l in its position of Figs. 19 and 29 except when the circuit through relay i3 is closed when cir-" cuits will be established at contact points i6, 18 and 7?, 19. A reset push button is located on the outer surface of the control cabinet and is adapted to close a circuit at 8| and 82 when moved in a downward resetting direction.

We will now refer to Figs. 3, 3A and 3B which in connection with mechanical constructions already described will more clearly indicate the operation of our invention, and its various functions. Fig. 3 shows a wiring diagram of the entire invention, and will be referred to in describing more particularly the operation of the coil SI for controlling the drawer, the operation of the mercur tubes and 85 which also function to control the drawer, and the operation of the electro-magnet 3!] for controlling the compartment i2 through switch points 35 and 35 operated by the bolt iii and the switch operating member 37. For describing the operation of the main and supervisory circuit through the coil 13, and the manner of reestablishing this circuit, we will preferably refer to Fig. 3A which illustrates the circuit in a schematic manner, so that its operation is more easily\understood than with reference to Fig. 3. Fig. 3B which is similar to Fig. 3A was drawn for the purpose of illustrating schematically the operation of the vigilante or alarm device in the circuit.

In Fig. 3A, normally the main protective circuit through the main alarm relay i3 is closed through contacts l -ll, conductor 85, conductor BE, resistance l6, battery 87, conductor 38, resistance 'il, conductor 89 and through the coil 13. In the closed condition of the circuit through the electro-magnet it, a supervising circuit is established also at switch points it and 18 which are shown electrically in Figs. 3 and 3A,

and which are shown mechanically in Figs. 19

and 20. This established circuit on one side is from the contact 18 through the conductor the battery 81 to conductor A. On its other side, it is from contact it through conductor 9i to main conductor B. The conductors A and B lead to the various drawers and other devices which are to be protected, and which I have shown in this application as embodied in the' drawer compartment 13 controlled by the main relay 5!, and in the combination lock compartment controlled by the relay 30.

In this closed position of the bank protecting circuit through conductors A and B, there will be maintained a closed external circuit through the coil 38 which controls access to compartment l2. This circuit is shown in Fig. 3 as through the main conductor A, conductor 92, switch points 35 and 38, coil 30 and back to conductor B. In this condition of the circuit through the electro-magnet 39, it will be quite obvious that it will be possible for the operator when retracting the bolts Hi, to actuate the member 31 to close the circuit at points 35 and 36 and thus cause the electro-magnet 39 to retract the dogging member 32 and permit full retraction of the bolts it. This operation is clearly understood when reference is made especially to Figs. l, 5, and 6. In this condition of the circuit through electro-magnet 3%, should an alarm be created in the bank, as by the closing of a circuit at any of the points 93 shown best in Fig. 3A, which may represent push buttons located throughout the bank, the main relay '53 will be immediately short circuited and will not receive the current required to maintain the contacts closed at 'i'i'i8 or at 16-48. It is obvious that this short circuit will be through contacts 93,

conductor 86, resistance 1!), battery 81 and conductor 88. The opening of the contacts 16- 18 will immediately destroy the outside circuit through the relay l3 itself and conductors A and B, which opens the circuit through the relay 3B regardless of the operation of the bolt l6 and the switch members 35 and 36, and it will be impossible to retract dogging detent 32 to obtain access to the compartment l2.

In order to obtain access to compartment l2 eventually, it is, therefore, necessary to reset the circuit as by push button 8B in the control cabinet 23 located in the compartment H. To do this it is required to set up the combination l8, retract the bolts it of the compartment ll, start the running of the delayed time movement 2| so that after the predetermined period of time for which this movement is set, it will be possible to reach into the compartment II and to operate the push button 86. The operation of this push button is best described and shown with reference to Fig. 3A in which it is quite obvious that a circuit will be closed at contacts 82, 8!, conductor 9%, conductor 85, conductor 86, resistance H1, battery 8?, conductor 88, resistance H, conductor 89, through the coil 13, and back through conductor 95 to the contact 82.

Obviously, this operation will have reestablished the circuit once more through the contacts TI, '89 and E8, E8 respectively by the attraction of the armature member M against its spring 15 so that the circuit of relay 13 is closed and the supervisory circuit is once more closed through the conductors A and B and therefore through the outside circuit of the electro-magnet 38.

Naturally, in so far as the control by relay 13 of the circuits through contacts 'H'I9 and 16- i8 is concerned, it is immaterial what type of structure is to be controlled, and how that structure is to be controlled through internal circuits dependent on the main supervisory circuit. Thus, the control by relay 13 is the same for the drawer l3 as for the compartment I2 which has just been described. Also, the resetting of the circuit through the relay i3 is entirely independent of the other circuits which the relay may control. I shall now describe more particularly the local or internal circuit of the drawer l3 whereby it is permitted to open and close while controlled externally by the electro-magnet T3 similarly to the control exercised over chest 12.

Under normal conditions, the external circuit through the drawer relay 6! will always be closed so that the operation of the relay under normal conditions will be entirely dependent on the operation of the drawer internal circuit comprising the push button 22 and the mercury tubes 64 and 65 which move as the drawer is operated into open and closed positions. In Fig. 3 and in Figs. 10 and 12, the drawer is illustrated in its closed position and with the circuit as naturally conditioned in that position. With the push button contact it? against the contact 532 and with the mercury tube 65 in its particular position with the mercury down at its lower end so that the contacts are open at point 83, there is no circuit through the coil 6!, contact Hi3, contact 02,.conductor ifl i, open contacts 83 and back to conductor A. It will now be impossible to open the drawer.

However, should the push button 22 be moved to close the circuit between contacts M13 and act, a circuit will be established through conductor B, conductor IOI, coil 6|, contacts I03 and H15, conductor its, contacts 84 of tube at, and conductor A. It will then be possible to move the drawer to an open position since the electro-magnet 6i will have acted to withdraw the dog member 58 out of the path of the locking cam 55 as shown mechanically in Fig. 13. As soon as the drawer has moved from the position of 10 to the open position of Fig. 11, the weighted portion 69 of the mercury tube carrying arm 62 permits the movement of the tube to the position of Fig. 11 wherein the circuit will be broken at control points 34 of tube tit and will be established at contact points as of the tube 65. This is done so that as soon as the drawer has moved outwardly somewhat, release of the push button to separate the contacts m2 and its will still permit the circuit to remain closed through the electro-magnet 6! so that the dog 58 will be able to cooperate with the spring pressed pawl member St in the position of Fig. 16 for maintaining the drawer in an open position. The circuit so established by the outward movement of the drawer accompanied by the release of button 22 to the position in Fig. 3 is as follows: Conductors B and till, coil iii, contacts M3 and I02, conductor Hi l, contacts 83 and conductor A.

In this position of the parts which is illustrated mechanically in Fig. 16, it is quite obvious that the circuit through the electro-magnet 5i may be easily broken by the movement of the push button 22 to reestablish the circuit through contacts Hi3 and W5 which will break the circuit through contacts Hi2 and H33 permitting the armature W of the electro-magnet 6i to assume its position of Fig. 17 so that the drawer will be allowed to close and assume its original locked position of Fig. 12. It is also possible in the position of the parts in Fig. 16, for any one of the push buttons 93 in the external circuit to be closed so that the main relay magnet it will break the external supervisory circuit through the electro-magnet 3! and thus disable the drawer, permitting it to be closed by closer 5i and to remain closed until the main relay circuit is reestablished by the push button at of the control cabinet 23 located in the compartment ll controlled by the delayed time mechanism.

Naturally, additional mechanisms may be placed under the control of the main relay id as shown in Fig. 3. Also a vigilante or alarm may be placed into the circuit as at lill to be set into operation immediately upon the closing of one of the alarm buttons 93 operable to throw off the relay 13. Preferably the alarm is operable by a predetermined increase in current therethrough or by a decrease as might be caused by the cutting of its external wires.

The electrical operation of the vigilante it? or alarm member iil'l, is shown in Figs. 3 and 3A, but is best illustrated schematically in Fig. 33, to which reference will now be made. Ordinarily, in the regular conditioning of the circuit, there will be a circuit established from the battery 8? through resistance ll, through the relay l3 and the resistance '52 in parallel, and then through the vigilante Hull and the resistance in parallel and back to the other side of the battery 8?. The electricity thus traversing the circuit and vigilante It]? is not sufiicient to positively actuate it, it being sufficient, however, for the proper actuationof the control relay 13. In case of an alarm, a circuit is closed at 83 which immediately short circuits resistances ll and i2 and control relay 13, so that a circuit is now established through the battery 83, contacts 93, and then through resistance ll! andvigilante till in parallel, and back to the other side of the battery 8?. v

The current now traversing the vigilante it! is of such considerable strength as to operate the vigilante and excite the alarm. As soon as the circuit is broken at points 93, the vigilante ill? will no longer operate and the circuit will be as follows: From the battery through resistances ll, ii in series, and then through the resistance it and the vigilante It? in parallel and back to the other side of the battery. The resistances H and '52 are now in series with the vigilante it! and there will obviously not be sufiicient current for the vigilante to. operate. When the button Bil is depressed so as to establish a circuit at 8l82 there will be a. closing of the circuit through the main relay it so as to reestablish the circuit into its original condition. Resistance iii is required not only to adjust the circuit through alarm ml, but to allow functioning of the electrical circuit in case the wires leading to alarm it? are cut.

An additional feature is the button I58 located in compartment is andwhich is positioned in the electrical circuit as shown in Fig. 3. This button is used to break the outside circuit through the relay Bl so that it will be impossible to open the drawer 53 unless one knows the combination of lock it so that the custodian of.

the drawer it may feel free to leave the same at any time without destroying the circuit through the other protected devices.
