Patent Images
1. A clamp for a vehicular battery, comprising:
- a) at least two jaws for attaching said clamp to a terminal of said battery; and
b) a longitudinal conductive member comprising a straight spring that is placed at a location in between said jaws and electrically connected to said clamp, said longitudinal conductive member constructed and arranged to come into contact with said terminal when the clamp is attached to the terminal.

Abstract
The invention is a novel clamp for a car battery jumper. The main deficiency in the various clamps used in car battery jumpers is the very small contact surface area, which chokes off the electric current and makes the task of starting the vehicle very difficult. The new clamp disclosed herein features a longitudinal structure consisting of a spring and a metal disk. Upon gripping the terminal of a battery, the metal disk included in the clamp comes into contact with the top surface of the battery'"'"'s terminal, thus insuring a large contact surface area and hence a substantially better starting current.
