Abstract
Abstract A combustion-engine vehicle includes a starting system which starts the engine in response to one of the vehicle's doors being operated. When the door is opened a circuit is completed from the vehicle's battery through a dome light switch to the ignition coil and to a starter-motor solenoid switch. A vacuum switch coupled to the engine's intake manifold opens the circuit to the starter-motor solenoid switch when it senses that the engine has been started. A door-sensor control connected between the dome light switch and the starter-motor solenoid switch and the ignition coil includes two on/off switches connected in series, with the starter-motor solenoid switch being connected to a downstream terminal of the first on/off switch and the ignition coil being coupled to a downstream terminal of the second on/off switch. The vacuum switch is connected in series in a line to the starter-motor solenoid switch.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
An automatic starting system for an internal-combustion engine powered vehicle having an operator's cab comprising: a starting means for starting said engine; a battery for energizing said starting means; one or more vehicle closure means providing access to the operator's cab; a closure sensor means for monitoring at least one of said closure means and for allowing energy to flow from said battery to the starting means and said engine in response to one of said closure means being opened; a closure sensor control means for selectively activating and deactivating the closure sensor means; an internal-combustion engine sensor which automatically interrupts the flow of energy to said starting means in response to said engine starting.
Claim 2
Dependent Claim
115 words
An automatic starting system for an internal-combustion engine powered vehicle having an operator's cab comprising: a starting means for starting said engine; a battery for energizing said starting means; one or more vehicle closure means providing access to the operator's cab; a closure sensor means for monitoring at least one of said closure means and for allowing energy to flow from said battery to the starting means and said engine in response to one of said closure means being opened; a closure sensor control means for selectively activating and deactivating the closure sensor means; an internal-combustion engine sensor which automatically interrupts the flow of energy to said starting means in response to said engine starting.
Claim 3
Dependent Claim
18 words
An automatic starting system as in claim 1 wherein said vehicle closure sensor is a dome light switch.
Claim 4
Dependent Claim
63 words
An automatic starting system as in claim 1 wherein said closure-sensor control means includes first and second on/off switches connected in series with said closure sensor means, a downstream terminal of said first on/off switch being connected to said starting means for starting said engine and a downstream terminal of said second on/off switch being connected to an ignition coil of said engine.
Claim 5
Dependent Claim
38 words
An automatic starting system as in claim 3 but further including a key operated valve means mounted in a fuel line of said internal-combustion engine for selectively allowing and not allowing fuel to flow to said internal-combustion engine.
Claim 6
Dependent Claim
67 words
An automatic starting system as in claim 1 wherein is further included a normally-closed combustion engine sensor switch connected to the intake manifold of said engine, said combustion engine sensor being coupled in series in the circuit from said closure sensor control means to said starting means for opening said circuit upon the starting of said engine in response to a reduced pressure in said intake manifold.
Claim 7
Dependent Claim
18 words
An automatic starting system as in claim 5 wherein said vehicle closure sensor is a dome light switch.
Claim 8
Dependent Claim
63 words
An automatic starting system as in claim 6 wherein said closure-sensor control means includes first and second on/off switches connected in series with said closure sensor means, a downstream terminal of said first on/off switch being connected to said starting means for starting said engine and a downstream terminal of said second on/off switch being connected to an ignition coil of said engine.
Claim 9
Dependent Claim
38 words
An automatic starting system as in claim 7 but further including a key operated valve means mounted in a fuel line of said internal-combustion engine for selectively allowing and not allowing fuel to flow to said internal-combustion engine.
Claim 10
Dependent Claim
39 words
An automatic starting system as in claim 1 but further including a key operated valve means mounted in a fuel line of said internal combustion engine for selectively allowing and not allowing fuel to flow to said internal-combustion engine.
