Abstract
Abstract An anti-theft device that is adapted to be connected adjacent to or on a battery of a motor vehicle and including a power switch for disconnecting the battery from its standard battery cable when current flowing through the cable exceeds a preselected substantial amount of current associated with an attempt to start the vehicle. A lockout circuit is actuated by a remote transmitter for generating an external command signal to override the operation of the power switch. This device can be attached directly to a battery without external wiring and still provide the passive or self-arming anti-theft device.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
203 words
An anti-theft device used with a battery of a motor vehicle having a starting circuit, said battery having first and second outwardly extending electrode post members, said anti-theft device comprising a support member, means for attaching said support member onto said battery, a switching means on said support member having a first position electrically connecting one of said electrode post members with said starting circuit and a second position electrically disconnecting said one of said electrode post members from said starting circuit, means for shifting said switching means to said second position upon receipt of a specific external command signal, comprising: said switching means including a first electrical conductor having a terminal end and fixedly connected to a clamping receptacle means for fixedly clamping said first electrical conductor to said first electrode post member, a second electrical conductor having a terminal end spaced from said terminal end of said first conductor to define a gap and having a substitute electrode post member, said switching means having a contact plate means for electrically connecting said terminal ends when said switching means is in said first position and a lock housing means for preventing unauthorized access to said clamping receptacle means and said switching means.
Claim 2
Dependent Claim
203 words
An anti-theft device used with a battery of a motor vehicle having a starting circuit, said battery having first and second outwardly extending electrode post members, said anti-theft device comprising a support member, means for attaching said support member onto said battery, a switching means on said support member having a first position electrically connecting one of said electrode post members with said starting circuit and a second position electrically disconnecting said one of said electrode post members from said starting circuit, means for shifting said switching means to said second position upon receipt of a specific external command signal, comprising: said switching means including a first electrical conductor having a terminal end and fixedly connected to a clamping receptacle means for fixedly clamping said first electrical conductor to said first electrode post member, a second electrical conductor having a terminal end spaced from said terminal end of said first conductor to define a gap and having a substitute electrode post member, said switching means having a contact plate means for electrically connecting said terminal ends when said switching means is in said first position and a lock housing means for preventing unauthorized access to said clamping receptacle means and said switching means.
Claim 3
Dependent Claim
73 words
The anti-theft device of claim 1, wherein said contact plate means includes a movable bar member operable to electrically connect said terminal ends, and said lock housing means includes a plate mounted to said battery and a lock post fixed onto said plate, and a cover for mounting on said plate, said cover having a key mounted thereon and adapted to oscillate a keeper to provide an interference fit with said lock post.
