Abstract
Abstract A direct current power supply is obtained from a battery equipped vehicle engine driven alternator by a circuit and a solenoid actuated vacuum operated battery disconnect switch. The solenoid is energized by a relay in response to closing the starting switch of a power tool connected to the alternator output wiring by the circuit.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
150 words
An alternator power source in combination with an accelerator equipped engine driving an alternator and having the alternator power output connected with a battery by wiring, the improvement comprising: a normally closed switch interposed in the alternator output to battery wiring; said normally closed switch having a pair of terminals; said normally closed switch being connected with said accelerator for opening said normally closed switch by movement of said accelerator in an engine accelerating direction; a solenoid operatively connected with said accelerator for moving said accelerator in an engine accelerating direction; normally open circuit means connected in series with said normally closed switch terminals; said circuit means including at least one relay and a pair of power output terminals; other wiring connecting said relay with said solenoid for energizing said solenoid when said relay is energized; and means bridging said power output terminals for energizing said relay and said solenoid.
Claim 2
Dependent Claim
150 words
An alternator power source in combination with an accelerator equipped engine driving an alternator and having the alternator power output connected with a battery by wiring, the improvement comprising: a normally closed switch interposed in the alternator output to battery wiring; said normally closed switch having a pair of terminals; said normally closed switch being connected with said accelerator for opening said normally closed switch by movement of said accelerator in an engine accelerating direction; a solenoid operatively connected with said accelerator for moving said accelerator in an engine accelerating direction; normally open circuit means connected in series with said normally closed switch terminals; said circuit means including at least one relay and a pair of power output terminals; other wiring connecting said relay with said solenoid for energizing said solenoid when said relay is energized; and means bridging said power output terminals for energizing said relay and said solenoid.
Claim 3
Dependent Claim
30 words
