Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
117 words
In an inertia operated battery disconnect device, comprising a male plug, bolt fastening means carried by said plug for securing it to the engine block, open prong means carried by said plug providing for electrical contact with a metal sleeve of a female member, a lead cylinder carried by said sleeve providing mass weight of such density so as to be acted upon by inertia when a vehicle collides, an electrical cable and lug carried by said female member for electrically securing it to a battery, a rubber sleeve carried by said female member providing insulation means for said female member so as to prevent it from becoming grounded when disengaged from said prong of said device.
Claim 2
Dependent Claim
117 words
In an inertia operated battery disconnect device, comprising a male plug, bolt fastening means carried by said plug for securing it to the engine block, open prong means carried by said plug providing for electrical contact with a metal sleeve of a female member, a lead cylinder carried by said sleeve providing mass weight of such density so as to be acted upon by inertia when a vehicle collides, an electrical cable and lug carried by said female member for electrically securing it to a battery, a rubber sleeve carried by said female member providing insulation means for said female member so as to prevent it from becoming grounded when disengaged from said prong of said device.
Claim 3
Dependent Claim
84 words
The combination according to claim 1, wherein said prong of said male plug is provided with opening means so as to enable it to expand or contract for easy entering of said sleeve extending from said lead weight cylinder of said female member, said sleeve of said lead weight cylinder having equally spaced apart openings opening for expansion and contraction, thus enabling good electrical contact with said prong of said male plug when said prong is inserted within said sleeve of said female member.
Claim 4
Dependent Claim
89 words
The combination according to claim 2, wherein said lead weight cylinder has embedded in the opposite end, an insulated battery cable having lug means for securement to a terminal of a battery, said lead weight cylinder having such mass and density that it will quickly move away from said male plug so as to open the circuit between the engine block and the battery of the vehicle, the inertia force caused by collision of said vehicle with an object, causing said female member to disengage from said male plug.
Claim 5
Dependent Claim
83 words
The combination according to claim 3, wherein, said female member is enclosed and secured by friction means, within said rubber sleeve, said rubber sleeve having an open end for receiving said prong of said male plug and said rubber sleeve having a closed end through which extends said battery cable, said rubber sleeve thus protecting said female member from becoming grounded on some part of the vehicle after separation from said male plug immediately following a collision of said vehicle with an object.
