Abstract
Abstract A battery disconnector particularly adapted for disconnecting the batteries of automobiles to prevent theft comprising a remote operated rotary switch having two fixed contacts, one to one of the cables of the battery, and the other preferably between the battery and the electric starting motor. A rotatable connector is adapted to carry the current between these contacts and is turned by a gear in turn operated by a pinion gear connected to a rotary shaft or the like which may be either locked by a key or have an operating handle hidden in an unexposed portion of the vehicle, e.g., under the dashboard.

Claim 1
Independent Claim
226 words
A battery disconnector comprising a permanently closed and welded housing including top, bottom, and side walls, a pair of electric contacts therein, means securing an electric cable to each said contact, said electric cables extending through certain walls of the housing, a rotary electric conducting connecting bridge having a position connecting the electric contacts and a position at an angle thereto disconnecting the contacts, a gear for rotating said bridge, and a pinion for said gear, an armored flexible shaft for operating said pinion, the flexible shaft being manually operable, the bridge and gears being completely concealed and unaccessible in the housing, said housing including a pair of opposite side walls, said cables entering said housing in opposite directions through said side walls, and said electric contacts being secured with respect to the ends of said cables at opposite sides of the housing, means rotatably mounting said electric connecting bridge adjacent the center of the housing between the top and the bottom thereof, opposed radially extending portions on the bridge to engage said electric contacts and to be disengaged therefrom depending upon the rotation of said gear, said contacts being of the spring clip type each including a pair of resilient arms for receiving between them the radially extending contacting ends of said bridge, and insulation between said bridge and both the housing and the gearing.
