Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
A battery cutoff switch comprising a tiered cylindrical insulator formed with a large diameter middle portion, and smaller diameter first and second end portions; first and second tubes of conductive material, said first tube surrounding said insulator first end portion, and said second tube surrounding said insulator second end portion and overlapping said insulator second end portion on the side opposite said insulator middle portion, whereby said insulator middle portion insulates said first conductive tube from said second conductive tube; said second conductive tube having battery terminal connecting means including the overlapping end thereof; two switch posts, one electrically and mechanically connected to said first conductive tube, and the other electrically and mechanically connected to said second conductive tube; a knife blade pivotally connected to one switch post and moveable to engage or disengage said second switch post, whereby a circuit between said first conductive tube and said second conductive tube and a battery terminal connected thereto is made or broken.
Claim 2
Dependent Claim
161 words
A battery cutoff switch comprising a tiered cylindrical insulator formed with a large diameter middle portion, and smaller diameter first and second end portions; first and second tubes of conductive material, said first tube surrounding said insulator first end portion, and said second tube surrounding said insulator second end portion and overlapping said insulator second end portion on the side opposite said insulator middle portion, whereby said insulator middle portion insulates said first conductive tube from said second conductive tube; said second conductive tube having battery terminal connecting means including the overlapping end thereof; two switch posts, one electrically and mechanically connected to said first conductive tube, and the other electrically and mechanically connected to said second conductive tube; a knife blade pivotally connected to one switch post and moveable to engage or disengage said second switch post, whereby a circuit between said first conductive tube and said second conductive tube and a battery terminal connected thereto is made or broken.
Claim 3
Dependent Claim
22 words
The battery cutoff switch of claim 1 wherein said battery terminal connection means further includes a set screw in said overlapping portion.
Claim 4
Dependent Claim
24 words
The battery cutoff switch of claim 1 wherein said first insulator end portion is of even smaller diameter than said second insulator end portion.
Claim 5
Dependent Claim
16 words
The battery cutoff switch of claim 1 wherein said insulator is a molded piece of plastic.
Claim 6
Dependent Claim
26 words
The battery cutoff switch of claim 1 wherein a pull cable is connected to the movable end of said knife blade to remotely operate said blade.
