Abstract
Abstract An apparatus and method for jumping or charging a discharged automobile battery in order to start an automobile. Jumper cables are provided having indicator lamps to insure correct polarity connecting of cables. A switch, controlled manually or by timer establishes connection between the charged and discharged battery to charge the latter for a predetermined period of time. A circuit breaker to automatically disconnect the circuit in a situation where a dangerously high content would flow.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
215 words
Apparatus for jumping a first battery to a second battery comprising: a first and second electrical jumper cable secured together throughout a substantial length thereof; a manually operable clamp secured to each end of each jumper cable to connect the jumper cable ends to battery terminals; switch means having contacts interposed in a circuit path of the second jumper cable having normally open contacts to open the electrical circuit of the second jumper cable thereby providing a first and second section thereof; first serially connected electrical diode and indicator means connected to the first cable and the first portion of the second cable; second serially connected electrical diode and indicator means connected to the first cable and the second portion of the second cable; each of said diodes being connected to conduct electrical current in the same direction relative to their respective connections between the first and second cables; manually operable means to control the said switch means; spring means connected to urge the manually operable means to a first position whereby the switch means contacts are in their normally open position; and means whereby the manually operable means may be manually moved to a second position to close the contacts of the switch means to close the circuit path of the second jumper cable.

Apparatus for jumping a first battery to a second battery comprising: a first and second electrical jumper cable secured together throughout a substantial length thereof; a manually operable clamp secured to each end of each jumper cable to connect the jumper cable ends to battery terminals; switch means having contacts interposed in a circuit path of the second jumper cable having normally open contacts to open the electrical circuit of the second jumper cable thereby providing a first and second section thereof; first serially connected electrical diode and indicator means connected to the first cable and the first portion of the second cable; second serially connected electrical diode and indicator means connected to the first cable and the second portion of the second cable; each of said diodes being connected to conduct electrical current in the same direction relative to their respective connections between the first and second cables; manually operable means to control the said switch means; spring means connected to urge the manually operable means to a first position whereby the switch means contacts are in their normally open position; and means whereby the manually operable means may be manually moved to a second position to close the contacts of the switch means to close the circuit path of the second jumper cable.
Claim 3
Dependent Claim
81 words
Apparatus as set forth in claim 1 in which the manually operable means is a pivotally mounted hand grip; said switch means including a switch pin in contact with the pivotally mounted hand grip; and said spring means being in contact with the end of the hand grip remote from the pivotal point thereof whereby the release of manual pressure on the hand grip causes it to pivot under the pressure of the spring means to open the said switch means.
