Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
139 words
A collision activated, automatic electric disconnect device for vehicles, comprising in combination, a base integral with a collar made of insulated material, means for mounting said base stationarily on said vehicle, means for connecting said disconnect device in the battery circuit of said vehicle and connectable means for connecting a weighted contact to said disconnect device such that a collision of said vehicle will cause said weighted contact to be disconnected from said disconnect device, thereby interrupting said battery circuit, wherein said connection means comprises a semi-circular resilient clamp around a central opening, and a weighted conductor snap fitted in said central opening, wherein said conductor comprises a conductive pin having an enlarged weight at its upper end and fulcrum means at its intermediate portion, a lower end of said pin having means to snap fit in said clamps.
