other instrumentality, is to prevent unauthorized use of the vehicle or other device on which it is installed, and to prevent tampering with any component attached to the vehicle or device. This is accomplished by eliminating the conventional cylinder and tumbler locks and replacing them with a multiple contact plug and socket. With a special key unit, coded, matched and mated with a door and/or with an ignition unit, the owner may look and unlock the doors and/or trunk, start and 'drive the vehicle, and turn off the ignition, in much the same way he would use the conventional key. There are a few changes in the location and operation of some of the components used in the present system that are already in use on the standard automobile. Further, if any other key unit or plug, or "jump wiring" is used in an attempt to unlock the doors of the car or to start the engine an alarm will be initiated to announce that the vehicle or other instrumentality has been tampered with. The present system is so constructed as to turn off all the major components, including the ignition, gasoline supply, electrical current to the various components, which system also includes setting an alarm against motion and unauthorized entry.

VEHICLE ELECTRICAL LOCKING AND ALARM SYSTEM BACKGROUND OF THE INVENTION of elements simultaneously.
The present electrical locking and alarm system is so constructed that it may have a multiplicity of stations which can be locked or set in such manner that an alarm will be sounded, if any one of theseveral stations is tampered with. Further it will operate to nullify effort 7 to cause the alarm to cease, which cannot be done until the proper contacts are brought into simultaneous contact relation with a master contact element or plug, which may be minaturized.
For purposes of description, the present electrical locking and anti-theft system utilizes a multiple contact element in the form of a socket or receptacle and a complementary multiple pin type plug, which, in the present instance, is shown to be a 10 pin plug and a complementary receptacle or socket. These are known by various trade names, such as Cannon, Amphenol,
Elco, Cinch-Jones and-others, however, in the present instance, a Cannon type plug and socket is shown,
which are preferably minaturized for convenience in carrying. v
For purposes of illustration, the present invention will be described as utilized on an automotive vehicle, but the invention is not to be limited thereto. In using the present invention on an automotive vehicle, it is preferable to have one or all of the doors or the body portion adjacent theretoto have a socket or receptacle thereon which is adapted to receive a complementary multi-pi'n plug. For purposes of illustration, however, these may be reversed, with the plug being attached to the vehicle. and the socket being the key. for operating the system.
To this multi-contact connection on thecar adjacent the door, or adjacent each door, circuit may lead to each element or facility which is to be protected, prior to the turning on of the ignition switch, and while only one multi-contact socket or receptacle has been shown, stubs of wires are shown leading therefrom to enable other sockets or multi-contact receptacles to be connected in parallel, so any door can be opened by the key" multi-point connector, such as a Cannon plug, which is wired internally so it will close the necessary circuits'to actuate the door mechanism to enable the door to be opened without setting off an alarm or performing other functions which would negate the opening of the door.
OBJECTSOF THE INVENTION An object of this invention is to provide an electrical lock and theft deterrent which will immobilize a number of key elements and provide an alarm system which will sound or otherwise spread an alarm, upon unauthorized tampering with the system.
Another objectof the invention is to provide an electrical locking and theft deterrent system which has a vast variety of combinations to be had without duplica- I tion, which makes the system practically infallible against short circuiting or jumping certain circuits without setting off an alarm and jamming the system so it cannot actuate until the precise multi-contact unit is employed to complementally engage the contacts of the system.
Still another object of the invention is to provide a circuitry which practically defies professional thieves trying to steal a vehicle on which the present system is utilized.
Yet another object of the invention is to provide a system which may be rewired and coded in a minimum of time so the multi-contact plug previously used will not perform the function of the newly wired and coded plug.
Still a further object of the invention is to provide a multi-contact member, such as a Cannon plug, the code of which will operate the door or doors and the ignition of an automotive vehicle without having to use a separate coded unit for each.
A final object of the invention is to provide an electrical locking and alarm system which is simple in construction, effective in operation, easy to recode, and relatively low in the cost of manufacture.
BRIEF DESCRIPTION OF THE DRAWINGS With the foregoing objects in mind and others which will become manifest as the description proceeds, reference is to be has to the accompanying drawings, in which:
FIG. I is a diagrammatic view of the wiring of an electrical locking and alarm system, which, in the present instance, is shown as applied to an automotive vehicle;
FIG. 2 is a perspective view of a multi-pin plug and a complementary socket shown in disconnected relation;
FIG. 3 is a diagrammatic view of the multi-pin portion of the connector as shown in FIG. 2, in aligned relation with the schematic wiring diagram, as shown in FIG. 1, but separated therefrom;
FIG. 4 is a view identical to FIG. 3, but in aligned relation with a second complementary socket or receptacle shown in FIG. I, but spaced therefrom.
DESCRIPTION OF THE INVENTION WIth more detailed reference to the drawing, like references characters designate like parts in the several views thereof. While the electrical locking and alarm system will be described in detail for use on a vehicle and more particularly a vehicle such as an automobile, it is not to be considered as limited thereto, and while the multiple pin plug and socket connector has been referred to as a Cannon plug, it is to be understood that any type multiple pin plug with complementary socket multi-point connector is within the scope and intent of the invention.
The controlling units of the present system are made up of two components, a multi-pin plug and a complementary socket electrical connectors, with one of the portions, for instance the female portion, being mounted on the door or doors or on the body of the vehicle adjacent the door or doors and on the cowl of a vehicle. In this manner the complementary portion, such as a plug, may be inserted into the socket, and if the wiring of the plug and of the socket is in mated, coded relation, it will perform a plurality of functions, which will be described in detail hereinafter.
The controlling units of the present system are made up of two portions, a multiple pin plug, which is designated generally at l, and a complementary socket or receptacle unit, designated generally at 2, which units are of the type known as a Cannon plug and socket. While the representation of the plug and socket is shown to have pins and 10 pin receptacles, this number may be varied according to thedegree of simplicity or complexity desired. However, 10 pins, A, B, C, D, E, F, G. H, I and J in plug 1 and 10 pin receptacles, a, b, c, d, e, fg, h, i andj in the socket 2, results in an almost infinite number of combinations, when calculated on a permutation and combination basis.
With the female portion of the receptacle unit 2 mounted on one of the doors or on the body of the vehicle adjacent one of the doors, or with a female receptacle unit 2 mounted, in the same manner, on or adjacent each of the doors, and with the circuitry of the several female receptacle units 2 connected in parallel, and coded and mated to be complementary to plug 1, the plug may be inserted into any of the receptacle units 2 to enable the circuit 13 to be closed to unlock a door (not shown) upon actuation of rocker switch 8 in one direction which will close circuits 10, 12 and 13 to actuate solenoid 14 to release the lock of a door, or through branch circuits 13A to unlock other doors,. Simultaneously the circuit 10 will energize circuit 10A, 10B to actuate solenoid 16C to open switch 16B to deenergize siren 20.
The controlling units of the present system are made up of two portions 1 and 2, comprising a multi-pin socket and Cannon" plug electrical connectors. The female portion 2 is shown in perspective in FIG. 2, however, it is shown diagrammatically as being wired into one portion of the electrical system, FIG. 1, and in FIG. 3 it is shown diagrammatically as wired into another portion of the electrical system, as shown in FIG. 1. The female socket portions 2 and 3, as shown in FIG. 1, may be duplicated for as many doors as the vehicle has, andare preferably mounted on the doors and on the cowl, respectively of the vehicle and are connected to circuits 5A and 58 respectively, which circuits are connected to a battery 5, FIG. 1. The battery 5 has a ground 5C connected thereto to enable the various circuits to be completed, as will be more fully brought out hereinafter.
'The sockets 2 and 3 on the doors and cow] respectively may selectively receive the multi-pin plug 1, which sockets may be located in substantially the same position'on the doors or on the body adjacent the doors and on the cowl, respectively, as the conventional tumbler locks and switches are now located. Multi-plug units 1, as shown in FIGS. 3 and 4, have identical wiring, but are shown in aligned relation with respect to the respective sockets 2 and .3, as shown in FIG. 1, to enable the circuits to be readily traced, however, in normal use, only one plug 1 will be used at one time. Another part of the multi-plug or key" unit-l is the three-position, on-off-on rocker switch 8 which is spring loaded to the center or of position. In event it is necessary to gain entrance to the plug 1, a removable cap 9 is provided on an end thereof, which allows emergency access to the terminal 22, as shown in FIGS. 2 and 3, which enables auxiliary electricity to be connected thereto to enable the plug 1 to perform the same functions as if the battery 5 was connected thereto. This holds true whether opening a door or doors and energizing the allied circuits associated with socket 2 or operating the circuit of socket 3, which circuits are allied with the ignition circuit.
In this manner an auxiliary battery may be pressed into service for temporary use.
It is to be pointed out that the multi-pin key" unit 1 may be selectively inserted into the sockets 2 and 3 in only one position, as the plug 1 has a slot 7 formed on a side thereof to complementally engage a rib or projection 11 in the respective sockets 2 and 3, as will best be seen in FIG. 2. As part of the combination these slots 7 and ribs or projections 11 may vary in width as well as in circumferential spacing around the periphery of the plug 1 and the diameter of the sockets 2 and 3. The location of slot 7 and rib or projection 11 is shown in the l 2 oclock position" in FIG. 2.
The number of slots 7 and of complementary ribs or projections 11 in each plug 1 and socket 2 or 3 may vary so that the plug and socket portions for one vehi cle or instrumentality to be locked will be complementary. The peripheral spacing of these respective portions may also vary to obtain an almost infinite number of combinations. Furthermore, a single slot and projection may vary only minutely in circumferential spacing to bring the proper multi-pin units of the plug into register with the proper receptacle in the socket. This is in addition to the internal wiring of the circuits within the plug, therefore the possible combinations would become inumerable, therefore the particular coded and mated plug, both for wiring and for slot and projection arrangement will fit only into a complementary socket to perform the desired function of opening or closing the circuits in accordance with the action of the rocker switch 8.
Should a plug 1 with a slot or slots 7 formed therein be inserted into a socket 2 or 3 to receive the slot or slots on the complementary projections 11, another main deterrent to tampering would be the wiring of plug 1 or of sockets 2 or 3, as there are many and varied ways that the plug and sockets may be wired. It is to be understood that the manner of wiring as shown in the drawings is representative of one of many ways the plug 1 and sockets 2 and 3 may be wired, as in a socket with 10 receptacles, any wiring arrangement may be connected to the receptacles.
To operate the present locking and alarm system, the multipin plug 1 forms the key which is inserted into the door socket 2. The battery 5 supplied power to socket 2 through receptacleftherein and to pin F in key 1. The key 1 has rocker switch 8 wired thereinto, as shown in perspective in FIG. 2, and as shown diagrammatically in FIGS. 3 and 4. With the rocker switch 8, within socket 2 accordance with the wiring shown therein, the rocker switch 8 is rocked toward'socket 2 and electrical current flows from battery 5 through wire 5A, receptacle f and pin F, and through wire 8A, through pin and receptacle B and b, respectively into wire 8B. This will energize fuel shut-off valve 4, which is a two position, solenoid actuated valve which will close conduit 6 against the flow of fuel therethrough. The fuel shut-off valve 4 is grounded, as indicated at 4A which permits the electricity passing therethrough to return to the ground 5C of battery 5, which fuel line is located between the fuel tank and the fuel pump of the vehicle, therefore the fuel to the engine is shut off.
The current flowing through wire 8B will flow through wire 8C tosolenoid l5 and to ground A to lock the door lock 158 to simultaneously lock all doors, which locks 15B are wired in parallel, through parallel wiring arrangement 8D. While only one door lock solenoid and door lock have been shown, it is to be understood that such units may be located on or adjacent to each door of the vehicle and operated simultaneously by actuation of rocker switch 8.
Furthermore, the current flows from wire 8B to wire SE to and through a two-position solenoid l6 and to ground 16A to close switch 168 to provide a live circuit, when the mail electrical circuit is de-activated, as will be more fully brought out hereinafter. In this manner the alarms are set and released for instant operation to sound an alarm and activate a visible signal, upon the vehicle or other instrumentality, with which the system is connected, being tampered with. Wire 56 is connected to the other sockets 2 which will be included for other doors.
A wire 5D is connected to wire 5E and leads to and through switch 168 tosiren 20, and with one branch connector 5E connected to terminal 17 on timer l8 and with wire 5F connected to terminal 17A the current passes through the timer 18 to one of the grounds 17B, 21E or 26B. that is made available when the vehicle or instrumentality is tampered with to form a circuit to the ground 5C of battery 5 to energize timer 18, when activated.
Electrical current from wire 88 flows through a branch wire 8F to a two-position solenoid 19 to open an off-on switch 19A, which current flows to ground 19B and returns to ground 5C of battery 5. This de-activates the normal electrical system of the vehicle or other instrumentality, as emergency circuits are provided for theft alarms and the like. With this operation electrical power to all the automotive electrical parts, except the door socket 2 and ignition socket 3 and emergency alarm solenoid switch 16, is turned off. With the doors now locked and with the fuel and electrical power turned off and the alarm set in position for activation, the operator may now leave the vehicle in a protected state. i
if the automotive vehicle or other instrumentality if tampered with, the siren 20 will sound and alert persons in the area, who should be prompted to notify authorities. The alarm may be activated in three ways. First, by opening any door, the hood or the trunk of the vehicle, while in locked" position, whereupon, microswitches 21A, 21B, and 21C, which are spring loaded, will be moved from open to closed position, as these are held openor in the off position by the closed door, hood or trunk, and while the term micro switch has been used, it is to be understood that any type spring actuated, normally closed switch may be used. With either of the switches 21A, 21B or 21C closed, current will be directed from the terminal 17A of timer 18 to ground 23E, a flasher mechanism 21 and therethrough to ground 5C and to battery 5. This action starts the timer on a cycle. During the cycle, power flows from battery 5, through circuit 5A, 5D and through switch 163, wires 5H, 5E and to terminals 17, 17C and 17D for a pre-set period of time, for instance, 1 minutev Power then flows to ground 21E to actuate signal lights 21D, in circuit 21F, and to simultaneously supply current from terminal 17D to sound signal relay 23 and to ground 23A to complete a circuit, which will close switch 23B, which will ground wire 20A of siren 20 so as to complete a circuit to the battery ground 5C.
When switch 238 is closed, current is directed from battery 5 through wire 5A, through wire 5D and switch 16B to the siren 20 and the timer 18 simultaneously. The closing of switch 238 grounds the siren 20 to cause the alarm to sound, when the timer completes its cycle, the switch 23B will return to open position, as shown in FIG. l, and the alarm signal will cease. The alarm may also be silenced and the lights turned off by inserting the proper key 3 and rocking the rocker switch 8 away from the door socket l to de-energize the solenoid 16 to open switch 16B. With the solenoid switch 168 open, the alarm sounding switch 23B, which is spring loaded, is returned to the position as shown in FIG. 1. A solenoid 16C is within circuit 10 and 10A, so when the circuit is closed by switch 8, the solenoid l6C-will "be energized to move switch 16B to open position.
A second method which initiates an alarm or signal is by grounding the terminal 17A when the motion detector switch 24 swings to contact a grounded ring 25 which causes a circuit to timer to pass from the battery 5 through wires 5A and 5D, closed switch 16B to the terminal 17 of timer 18 to close a circuit through the timer 18. The motion detector switch 24 is a pendulum type switch and will be actuated either by tilting the vehicle or by pushing or pulling the vehicle, therefore, all of alarm signals heretofore mentioned will be activated.
The third manner in which the alarm signals are set off is when the terminal 17A becomes grounded through the action of a tamper detection solenoid 26, which solenoid 26 is connected to a wire 26A which, in turn, is connected to wires leading to receptacles a, c, e, g, and i of socket 2 and receptacles k, m, 0, q, and s of socket 3. A wire 26B is connected to wire 26A and leads to another door socket 2 to perform the same function as pointed out for wire 26A. If any of these receptacles or wires leading therefrom are connected to a hot wire, the solenoid 26, which is grounded as indicated at 26B, will close switch 26C, which will cause electrical current to flow from wire or conductor 26A, through switch 26C to wire or conductor 26D to the terminal 17A of the timer 18, which timer is internally wired so as to direct current to the alarm signals in the same manner as herein before set out. The timer will be on for specified intervals, as heretofore set out.
As pointed out above, the key 1 is a multi-pin plug which fits within a multi-receptacle socket 2 or 3, and in the present instance, is a 10 pin plug and a 10 receptacle socket known as the Cannon plug and socket. A s pointed out above, five of these pins in each socket are connected to a wire 26A which energizes the solenoid 26, which is grounded at 268, to close switch 26C. Therefore, an attempt to short circuit any combination of pins and receptacles will result in setting off an alarm. If the short circuit is not immediately rectified,
' the alarm will continue intermittantly until the proper coded plug or key 1 is fitted into the proper socket.
When the vehicle is to be used, the operator must first insert the multi-pin key unit 1 into the door socket 2, then the rocker switch 8 is rocked away from the socket 2. This action closes a circuit from battery through wire 5A to receptacle f, pin F and through the rocker switch 8 into wire 10, thence through wire 12, and simultaneously through pin D and receptacle d, throughwire 13 to solenoid l4 and to ground, thereby unlocking the door. At the same time the current passes through pin H into receptacle h and into wire A to solenoid 16B to ground, which will open switch 168 to de-energize the alarm system and the timer 18. With the alarm turned off, the doors may be opened.
The operator then removes the key 1 form the socket 2 and places the key 1 in the socket 3, which will be referred to as the ignition socket. Plugging the key 1 into the socket 3 closes a circuit from battery 5 through wire 58, receptacle p, pin F, through wire 80, through pin J and through receptacle I, through ignition wire 27 to energize coil 28 which supplied current to distributor 29, which distributor is grounded at 29A, therefore, so long as the key 1 is in ignition socket 3, the ignition is turned on. The switch 8 is then rocked toward socket 3 and the circuit is closed to direct current from pin 10F to switch 8 into wire 8A and through pin B, receptacle l into wire 3A, which leads to solenoids 19C and 30 and to ground 30A, which will close switches 19A and 30 which will direct current from the battery 5, through switches 19A and 308 to a wire'or conductor cable 30C to energize starter motor 31 which motor is grounded as indicated at 31A. Simultaneously, current is directed from wire 3A into wire 3B to electrically operated solenoid valve 4 and to ground 4A, which will open the valve and the fuel line 6. The motor of the vehicle is rotated by the starter until it starts, whereupon, the operator releases rocker switch 8, which is spring loaded, to return to the center or of position and the vehicle may be driven in the normal manner.
When the operator wished to turn the engine of the vehicle off, he must physically remove the multi-pin key 1 from the ignition socket 3, thus breaking the current to the coil 28 and distributor 29. Since many automobiles have locks with which switches are associated, have exposed wires which are readily accessible, it is easy to wire around the lock switch, as usually only one factor has to be overcome, after the thief gains access into the car, to enable the car to be started. However, when a multiplicity of factors are disrupted and have to be overcome, as for instance the fuel supply is cut off, the starter motor circuit is disrupted, the ignition circuit immobilized, as well as various other hazards being presented to the thief trying to start the car, such as setting off sound or light signals, or both, makes a car, having the present system installed thereon an an undesirable risk.
In order to open the trunk, the operator must first insert key 1, FIG. 4, into ignition socket 3, whereupon, the switch 8 is rocket away from the socket 3, which closes a circuit, thereby causing the current to flow from battery 5, through wire SE to receptacle p, pin F and with the switch 8 closed, current will flow through wires 10 and 12 to pin D and through receptacle n thence through wire 12A to solenoid 32, through wire 12B and through relay switch 238 to ground 23A, which actuates solenoid 32 to unlock trunk lock 32A. The solenoid 32 is of the character that, when the trunk is closed, it will automatically lock, as by a spring latching arrangement.
When the trunk is unlocked, the operator has gained access to the battery 5 and the the various component parts that go to make up the operating mechanism for the locking and alarm system, as well as the timers and detectors, but the difficulty in gaining access to the system without the proper key, makes the vehicle less accessible to a potential thief.
In event of a dead or weak battery, access to the trunk is made possible by emergency terminal 22, as has been brought out above, wherein the conductor is connected to terminal 22 and to the positive side of battery 5, and the negative side of the battery is connected to a ground element on the vehicle. The key 1, FIG. 3, may be inserted in the door socket 2 and the door opened, then the key 1 may be moved into the position as shown in FIG. 4, and inserted into socket 3 to open the trunk, in the manner herein before set out, thus allowing access to thebattery.
