Abstract

A replacement for a battery ground wire has an insulated wire extending from a battery terminal to a unit disposed at a selected location in an automobile and operable by a key to connect and disconnect the wire to the automobile body as a ground for the battery for selectively disabling the electrical system as a security measure and a hood lock connected in the circuit prevents hood opening during disconnection of battery to ground.

Claims

1. An automobile security system comprising,

an elongated insulated cable adapted for connection to a ground terminal of the automobile battery in place of the ground wire thereof,

an operating unit adapted for physical and electrically connection at a first electrically conducting portion thereof through a metal portion of an automobile body,

such operating unit having a second electrically conducting portion electrically insulated by a hollow insulator from said first portion and electrically connected to said cable,

an interior electrically conducting movable element disposed for movement into and out of electrical connection between said first and second portions through said hollow insulator by threaded engagement with the interior of said first portion to controllably engage a surface of said second portion and

an operator adapted for insertion into said operating unit engaging said movable element for movement thereof into and out of electrical connection with said second portion of said operating unit to controllably disable all electrical circuits of said automobile.

2. The system of claim 1 further defined by

said operating unit including a hollow elbow-shaped insulator having said first portion secured at the top thereof and said second portion disposed in a perpendicularly extended bottom portion of said insulator with an end disposed in spaced alignment with said first portion for engagement by said movable element.

3. In an automobile security system having an elongated insulated cable connected to a ground terminal of an automobile battery in placed of the ground connection thereof,

an operating unit having a first portion connected to an automobile body and a second portion connected to the cable and insulated from the first portion with an interior movable element movable into and out of electrical contact between said first and second portions,

an operation configured to engage said movable element within said operating unit for movement of said element into and out of electrical connection between said first and second portions of said operating unit, the improvement comprising,

an auxiliary hood latch including means for mounting in an engine compartment of an automobile and including

a pivotally mounted latch member configured to engage a member depending from an automobile hood for securing the hood in closed position,

an element normally biased to prevent pivoting of said latch member,

a coil disposed to magnetically move said element away from said latch member to release same for pivoting, and

electrical connections connecting said coil between electrical ground and the ungrounded side of the automobile battery,

whereby said latch is locked during ungrounding of the battery by said operating unit and is unlocked to be pivoted by coil energization during grounding of said battery by said operating unit.

4. An automobile security system comprising,

an operating unit having a first portion connected to an automobile body and a second portion connected through a cable to a ground terminal of an automobile battery in place of a battery ground wire and an internal movable element in said operating unit movable to connect and disconnect said first and second portions,

an operator insertable in said operating unit for engaging said internal movable element for movement thereof into and out of electrical connection between said first and second portions of said operating unit to controllably disable the electrical circuits of said automobile;

and

an auxiliary hood latch for a hood of an automobile having means for mounting said latch within an automobile engine compartment and having a coil connected between electrical ground and the ungrounded side of the automobile battery for releasing said latch only during coiled energization, and

an emergency connector including a terminal electrically connected to the ungrounded side of said coil and adapted for disposition exteriorly of the automobile engine compartment whereby said coil may in emergency be energized by an exterior battery to release said hood latch.
