Abstract
Abstract A self-contained portable apparatus for charging dead batteries. The apparatus includes an alternator which is driven by a gasoline motor. A first circuit which includes cables extends from the alternator to the dead external battery. A charge initiating battery is mounted on the chassis, and is included in a second parallel circuit. The charge initiating battery energizes the alternator for causing such to begin charging the dead external battery. A third circuit is provided for regulating the voltage from said alternator so that the apparatus can be used to charge different potential batteries.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
222 words
A self-contained portable battery charging apparatus which can be conveniently carried to the site of a dead battery which is to be charged, said dead battery being external to said apparatus comprising: a small portable chassis; a low horsepower gasoline operated motor mounted on said chassis having an output shaft; an alternator mounted on said chassis coupled to said output shaft of said motor; a first circuit connecting said dead battery to said alternator; said first circuit including cables extending from said alternator to the terminals of said dead battery; a charge initiating battery mounted on said chassis; a second circuit connecting said charge initiating battery in parallel with said first circuit; first manually operated swiTch means interposed in said second circuit for selectively opening and closing said second circuit for energizing a field winding of said alternator causing said alternator to charge said dead battery when closed, so that when said first switch means is closed current flows from said alternator to both said charge initiating battery and said dead battery and after said alternator begins charging said dead battery said first switch means can be opened disconnecting said charge initiating battery from said alternator while said motor and alternator continue charging said dead battery; whereby an efficient portable charging apparatus is provided for charging completely dead batteries at remote locations.
Claim 2
Dependent Claim
222 words
A self-contained portable battery charging apparatus which can be conveniently carried to the site of a dead battery which is to be charged, said dead battery being external to said apparatus comprising: a small portable chassis; a low horsepower gasoline operated motor mounted on said chassis having an output shaft; an alternator mounted on said chassis coupled to said output shaft of said motor; a first circuit connecting said dead battery to said alternator; said first circuit including cables extending from said alternator to the terminals of said dead battery; a charge initiating battery mounted on said chassis; a second circuit connecting said charge initiating battery in parallel with said first circuit; first manually operated swiTch means interposed in said second circuit for selectively opening and closing said second circuit for energizing a field winding of said alternator causing said alternator to charge said dead battery when closed, so that when said first switch means is closed current flows from said alternator to both said charge initiating battery and said dead battery and after said alternator begins charging said dead battery said first switch means can be opened disconnecting said charge initiating battery from said alternator while said motor and alternator continue charging said dead battery; whereby an efficient portable charging apparatus is provided for charging completely dead batteries at remote locations.
Claim 3
Dependent Claim
35 words
The battery charging apparatus as set forth in claim 1, further comprising: a voltage regulating circuit coupled to said first circuit for regulating the output voltage being supplied from said alternator to said dead battery.
