Coin or token operated portable car starter
First Claim
1. In a storage battery emergency supply, a source battery having a jumper cable connected to one of its terminals, normally open switch means connected to its other terminal and a second jumper cable connected to said switch means whereby a vehicle battery which requires emergency power may be readied for connection to the source battery by connecting said jumper cables to those terminals of the vehicle battery which correspond to the terminals of the source battery to which the respective jumper cables are connected,sensing means for electrically sensing when the jumper cables are connected correctly to the corresponding terminals of the vehicle battery and for readying said switch means for closure,token responsive means for effecting closure of said switch means, andan indicator means actuated in sequence first by the sensing means and secondly by the token responsive means.

Abstract
A hand truck type of device provides a portable jumper battery for motor vehicles. Battery cables which connector clips are stored in the truck as is a power cable for connection to a power outlet so that the jumper battery may be recharged by a charger carried by the hand truck. Electronic circuitry connected to the cables prevents connection to the jumper battery until the connector clips have been properly connected and the vehicle battery has sufficient charge to be sensed. The sensing actuates a periodic signal and permits the system to be turned on. A token responsive switch controls a cycle timer which allows the circuitry to complete the connection to the vehicle battery.
