- the ignition switch, starter switch, starter motor, solenoid and battery are interconnected in a conventional manner and the internal combustion engine is also conventionally started by closing the ignition switch which is normally accomplished by means of a key and then closing the starter switch to activate starter solenoid 7 and energize starter motor 5.

- Transmitter 2 is preferably a single band portable transmitter that can readily be carried from place to place. Transmitter 2 would normally be located remote from the internal combustion engine. Receiver 4 would normally be a single band receiver that is tuned to the frequency of the transmitter. Receiver 4 is mounted on the internal combustion engine or in close proximity thereto. Receiver 4 obtains its operating power from battery 9 as is shown in the FIGURE.

The reason that relay 12 remains latched will become apparent later.

- solenoids 8 and 10 are activated, relays 12, 14 and 16 are energized as before. Since relays l2 and 16, as was pointed out above, are the type of relays that remain latched until energized for a second time, these relays will now open contacts 66 and 62. The opening of contacts 62 and 66 stops the internal combustion engine. This is, of course, obvious since ignition switch 1 is opened when relay arm 76 moves off of contact 66.
- relays 12 and 14 operate provides the ability to start and stop the engine by means of transmitter 2 and receiver 4. If relay 12 were not the type of relay that latched close when initially energized and then latched open when subsequently energized, the turning on of transmitter 2 would always activate starter solenoid 7. Since relay 12 remains closed on contact 62 while the engine is running and then opens when it is again energized, no voltage is applied to starter solenoid 7 during the stopping process. Relay l4 of course closes on contact 64 every time this relay is energized. However, the closing of contact 64 has no effect on starter solenoid 7 during the stopping procedure because contact 62 opens as soon as it is energized. In order to insure that contact 62 is opened before contact 64 is closed, relay 12 can be a slightly faster acting relay than relay 14.
- the apparatus of this invention provides a simple and straight forward means for starting and stopping an internal combustion engine. Only simple circuit elements such as relays and solenoids are used in combination with the transmitter and receiver. In this respect it should be noted that the solenoids provide isolation of the high starting current from radio receiver 4. This, of course, is necessary to prevent damage to receiver 4.

Of course, the invention could also be incorporated into the engine starting system at the manufacturing plant.

IGNITION COIL IGNI ION SWITCH STAKTE R SWITCH REMOTE CONTROL STARTING DEVICE FOR INTERNAL COMBUSTION ENGINE BACKGROUND OF THE INVENTION This invention relates to remote starting systems for internal combustion engines and, more particularly, to a radio frequency remote starting system for internal combustion engines.
In some instances, internal combustion engines provide power for operating other devices that are located in a remote position from the internal combustion engine, for example electric welders. These engines, of course, are equipped with conventional ignition and starting systems. These conventional systems are, of course, located at the site of the engine and therefore one can stop and start the engine only by going to the engine itself.
In those cases where a tool is being operated remotely from the engine, such as in electric welders, the ability to remotely start the internal combustion engine would be highly desirable. The ability to remotely start and stop the engine of a gasoline powered electric welder, for example, conserves fuel, eliminates unnecessary noise when the welder is not in use, and also eliminates the labor of going to the welder each time to stop or start the unit. Remote control starting devices for internal combustion engines are known in the art. Some of these prior art systems do use a transmitter and receiver to start the engine. However, in some of the systems the engine can only be started and not stopped. In those prior art systems that provide both the ability to start and stop the system, the circuitry involved is rather complex which adds to the overall expense of the system. This invention provides a relatively simple and inexpensive system for both starting and stopping an internal combustion engine. The system can be readily incorporated into any existing internal combustion engine and in no way interferes with the conventional starting system of the engine. Furthermore, the remote starting system can be totally uncoupled from the engine starting system by means ofa onof switch that is provided with the system.
SUMMARY OF THE INVENTION A remote starting and stopping radio frequency system for internal combustion engines is disclosed. The system comprises a portable transmitter located remote from the internal combustion engine. The internal combustion engine is equipped with a receiver and a plurality of relays and solenoids. In addition, an onoff" switch is provided at the engine to totally disable the remote starting system. The solenoids and relays are responsive to the output of the receiver which provides and output signal in response to a signal received from the transmitter. When the receiver provides an output, the engine will be either started or stopped as the case may be if the disabling switch is in the on" position. The remote starting circuitry is connected in parallel with the conventional starting circuitry of the internal combustion engine so that the remote starting circuitry in no way interferes with conventional starting of the engine even when the disabling switch is in the on position.
It is therefore an object of this invention to provide a remote control system for internal combustion engmes.
It is another object of this invention to provide a remote starting system for internal combustion engines.
It is still another object of this invention to provide a remote control stopping system for internal combustion engines.
It is a further object of this invention to provide a radio frequency remote control starting system for internal combustion engines.
It is still a further object of this invention to provide a radio frequency remote control stopping system for internal combustion engines.
DESCRIPTION OF THE DRAWING The above mentioned and other objects of the invention will become readily apparent from the following detailed description when read in conjunction with the annexed drawing in which the single FIGURE shows a preferred embodiment of the invention.
DESCRIPTION OF THE INVENTION The single FIGURE shows a preferred embodiment of the invention and the conventional starting apparatus of an internal combustion engine. Generally, the starting apparatus of an internal combustion engine comprises, as shown in the FIGURE, an ignition switch 1, a starter switch 3, a starter motor 5, a starter solenoid 7, and a battery 9. The ignition switch, starter switch, starter motor, solenoid and battery are interconnected in a conventional manner and the internal combustion engine is also conventionally started by closing the ignition switch which is normally accomplished by means of a key and then closing the starter switch to activate starter solenoid 7 and energize starter motor 5. Since all this circuitry and the operation thereof is conventional and well known, a complete description thereof is not deemed necessary.
The apparatus of this invention, as shown in the FIG- URE, comprises a transmitter 2, a receiver 4, a first solenoid 8, a second solenoid 10, a first relay 12, a second relay 14, a third relay 16, an on-off switch 24, and a terminal board 6 utilized to interconnect the various components of the invention to each other and to the conventional starting apparatus.
As shown in the FIGURE, the output of receiver 4 is connected to the terminals 22 of terminal board 6 by means of the conductors 26. The coils of solenoids 8 and 10 are also connected to terminals 22 by means of the conductors 28 and 30, respectively. Solenoids 8 and 10 are connected to each other by means of the conductors 38. Solenoid 8 is also connected to relays 12 and 14 by means of the conductors 34 and 36, respectively. Relay 12 is connected to relay 14 by means of the conductor 40 and to one of the two terminals 20 by means of the conductor 42. Relay 14 is connected to the other terminal of terminals 20 by means of the conductor 44. The terminal 20 connected to relay 12 is also connected to starter solenoid 7 by means of the conductor 46. The terminal 20 that is connected to relay 14 is connected directly to the ground 11. Solenoid 8 is also connected to battery 9 through the switch 24 by means of the conductor 32. Relay 16 is connected to solenoid 10 by means of the conductors 48 and to the terminals 18 of terminal board 6 by means of the conductors 50. Terminals 18 are also connected to ignition switch 1 by means of the conductors 52.
Now that the apparatus of the invention and the manner in which it is interconnected has been described, the operation thereof will be described. When on-off" switch 24 is in the of position as shown in the FIG- URE, the remote control circuitry of this invention is effectively disconnected from the starting circuitry of the internal combustion engine and therefore the engine cannot be started remotely. In order to use the remote control apparatus of this invention, switch 24 must be first switched to the on position. It should be noted however that even though the internal combustion engine can now be started remotely with the apparatus of this invention, the engine can still be started in a conventional manner even though switch 24 is on. The circuitry and apparatus of this invention as should be obvious from the above description, is connected in parallel with the conventional starting system and therefore does not prevent starting of the engine by this conventional system.
For purposes of this discussion, assume that the internal combustion engine is not running, that switch 24 is in the on position and that one now desires to start the engine. To so start the engine, one energizes transmitter 2 thereby transmitting a signal to receiver 4. In response to the transmitted signal, receiver 4 provides an output voltage at terminals 22 of terminal board 6. This voltage activates solenoids 8 and 10. When solenoids 8 and 10 are activated, relays 12, 14 and 16 are energized. When relay 12 is energized, the relay arm 72 is closed on the contact 62. Similarly, the relay arm 74 is closed on the contact 64 of relay 14 and the arm 76 is closed on contact 66 of relay 16 when these two relays are energized. When contact arm 76 is closed on contact 66, ignition switch 4 is closed. The closing of contacts 62 and 64 of relays l2 and 14, respectively, applies power to starter solenoid 7 to activate this solenoid and thereby energize starter motor 5 to start the internal combustion engine. Transmitter 2 is kept energized until the internal combustion engine is started. At that point the transmitter is turned off. When transmitter 2 is turned off after the engine has started, relays 16 and 12 remain closed on contacts 66 and 62, respectively. Whereas, arm 74 of relay 14 moves off of contact 64 to open this contact when transmitter 2 is turned off. Relays 12 and 16 are the type of relay that closes when energized and remains closed until the relays are again energized. Upon the second energization of these relays, the relays are opened. Relay 14 on the other hand is a type of relay that closes only when energized. It is, of course, obvious why relay 16 must remain closed on contact 66. If the relay did not remain closed on this contact, ignition switch 1 would be open and the engine would stop. Thus, relay 16 in effect operates as the ignition key for the engine. The reason that relay 12 remains latched will become apparent later.
Assume now that the engine is to be stopped. To stop the engine, transmitter 2 is again turned on to transmit a signal to receiver 4. Receiver 4 again provides an output voltage at terminals 22 in response to the signal from transmitter 2. This voltage at terminals 22 again activates solenoids 8 and 10. When solenoids 8 and 10 are activated, relays 12, 14 and 16 are energized as before. Since relays l2 and 16, as was pointed out above, are the type of relays that remain latched until energized for a second time, these relays will now open contacts 66 and 62. The opening of contacts 62 and 66 stops the internal combustion engine. This is, of course, obvious since ignition switch 1 is opened when relay arm 76 moves off of contact 66. This re-energization of relay 14 and thereby the closing of relay arm 74 on contact 64 has no effect on starter solenoid 7, since arm 72 of relay 12 moves off of contact 62 when relay 12 is re-energized. Thus, even though relay 14 is closed on contact 64, no voltage is applied to starter solenoid 7 since contact 62 of relay 12 is now open. When the internal combustion engine has stopped, the transmitter is turned off and all the relays are no longer energized. Contacts 62, 64 and 66 are now all open. These contacts will remain open until the relays are again energized.
The manner in which relays 12 and 14 operate provides the ability to start and stop the engine by means of transmitter 2 and receiver 4. If relay 12 were not the type of relay that latched close when initially energized and then latched open when subsequently energized, the turning on of transmitter 2 would always activate starter solenoid 7. Since relay 12 remains closed on contact 62 while the engine is running and then opens when it is again energized, no voltage is applied to starter solenoid 7 during the stopping process. Relay l4 of course closes on contact 64 every time this relay is energized. However, the closing of contact 64 has no effect on starter solenoid 7 during the stopping procedure because contact 62 opens as soon as it is energized. In order to insure that contact 62 is opened before contact 64 is closed, relay 12 can be a slightly faster acting relay than relay 14.
From the foregoing description it is quite obvious that the apparatus of this invention provides a simple and straight forward means for starting and stopping an internal combustion engine. Only simple circuit elements such as relays and solenoids are used in combination with the transmitter and receiver. In this respect it should be noted that the solenoids provide isolation of the high starting current from radio receiver 4. This, of course, is necessary to prevent damage to receiver 4. It should also be obvious from the foregoing description that this invention can be readily added to any existing internal combustion engine. Of course, the invention could also be incorporated into the engine starting system at the manufacturing plant.
