Abstract
Abstract A battery charger device characterized by a pair of cigarette lighter plugs having their negative contacts coupled together by a conductor and having their positive contacts coupled together by a self-resetting circuit breaker. In use, one of the plugs is inserted into the cigarette lighter socket of a car having a discharged battery and the other plug is inserted into the cigarette lighter socket of another car having a good battery. If the discharged battery starts to draw current that is greater than a predetermined level the current flow is regulated by a rapid cycling on and off of the circuit breaker. When the current drawn by the discharged battery is less than the predetermined level the circuit breaker conducts current between the two batteries with only insignificant IR loss.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
A battery charger device with current pulse regulation comprising first plug means engagable with the cigarette lighter socket of a first vehicle, said first plug means having a first negative contact and a first positive contact, second plug means engagable with the cigarette lighter socket of a second vehicle, said second plug means having a second negative contact and a second positive contact, said first negative contact and said second negative contact defining a negative contact pair, and said first positive contact and said second positive contact defining a positive contact pair, means coupling one of said negative contact pair and said positive contact pair together to create a first coupled pair, and a self resetting, two terminal circuit breaker means coupling the other one of said negative contact pair and said positive contact pair together to create a second coupled pair, said circuit breaker means opening when the current through it exceeds a predetermined level and automatically closing thereafter.
Claim 2
Dependent Claim
160 words
A battery charger device with current pulse regulation comprising first plug means engagable with the cigarette lighter socket of a first vehicle, said first plug means having a first negative contact and a first positive contact, second plug means engagable with the cigarette lighter socket of a second vehicle, said second plug means having a second negative contact and a second positive contact, said first negative contact and said second negative contact defining a negative contact pair, and said first positive contact and said second positive contact defining a positive contact pair, means coupling one of said negative contact pair and said positive contact pair together to create a first coupled pair, and a self resetting, two terminal circuit breaker means coupling the other one of said negative contact pair and said positive contact pair together to create a second coupled pair, said circuit breaker means opening when the current through it exceeds a predetermined level and automatically closing thereafter.
Claim 3
Dependent Claim
54 words
A battery charger device as recited in claim 1 further comprising a light emitting device including a first lead, and a second lead, first means coupling said first lead to a first terminal of said circuit breaker means, and second means coupling said second lead to a second terminal of said circuit breaker means.
Claim 4
Dependent Claim
19 words

Claim 5
Dependent Claim
47 words
A battery charger device as recited in claim 3 wherein said first means includes a multi-position switch which couples said first lead to said first terminal when in a first position and which uncouples said first lead from said first terminal when not in said first position.
Claim 6
Dependent Claim
50 words
A battery charger device as recited in claim 4 further comprising a two terminal flasher means having one terminal coupled to said first coupled pair and its other terminal coupled to a second position of said multi-position switch to be selectively coupled to said first lead of said light bulb.
Claim 7
Dependent Claim
31 words
A battery charger device as recited in claim 5 wherein said multi-position switch means includes a third position whereby said first lead may be selectively coupled to said first coupled pair.
Claim 8
Dependent Claim
