Remote control automobile engine starting apparatus

Claim 1

A remote control starting apparatus for an automobile engine having a carburetor with controls for increasing fuel delivery and choking, a storage battery, an ignition system having a coil, a starter motor having a starter solenoid switch for connecting the starter motor and the battery, the apparatus including: a. a remote control panel having normally open first, second, and third switches, b. a normally open circuit connecting the battery and the coil adapted to be closed by operation of a first relay connected to the battery through the first switch, c. a solenoid having a plunger connected to the carburetor fuel controls, the solenoid being adapted to be energized by the battery by operation of a second relay connected to the battery through the second switch on the remote panel so as to increase fuel delivery to the carburetor, d. a normally open starter circuit connecting the starter solenoid switch and the battery adapted to be closed by operation of a third relay connected to the battery through the third switch on the remote control panel for connecting the starter motor and the battery, e. an indicator light on the panel connected to the battery in a normally opened first monitoring circuit, f. a normally closed vacuum-operated switch in circuit with the third relay and in the first monitoring circuit responsive to development of vacuum in the carburetor to open the starter circuit when the engine starts so as to disengage the starter motor and the battery and to close the first monitoring circuit when the engine starts for providing visual evidence of engine start, said vacuum-operated switch including; a chamber communicating with the carburetor intake, a flexible diaphragm closing one end of the chamber and being movable inwards and outwards of the chamber in response to variations in air pressure in the chamber, a spring normally urging the flexible diaphragm in a direction outwards of the chamber, an operating shaft connected at one end to the diaphragm for movemEnt therewith, a grounded contact element engaged with the operating shaft for movement therewith, a pair of contact elements one being connected in circuit with the third relay and the other being connected to the indicator light through the first monitoring circuit disposed on opposite sides of the grounded contact element, disposed so that the starting circuit is normally closed and opens only when the engine starts and the first monitoring circuit is normally open and is closed only when the engine starts.
