Apparatus for transferring power from the battery of a service vehicle to the battery of a second vehicle, wherein the final connection between the batteries is made from a remote location via a radio transmitter and a receiver which is mounted in the casing of the apparatus to actuate a solenoid in response to a signal from the transmitter. The circuit between the solenoid and the receiver includes a transistor to control current through the solenoid coil and the base of the transistor is connected to the battery of the second vehicle. Cables used to attach the apparatus to the second vehicle battery are wound on a spool having an interrupted ratchet on one end thereof, the ratchet engaging a ratchet lock that pivots in one direction to hold the reel when the reel is turned in one direction to pay out the battery cables and the ratchet lock pivoting in the other direction within a ratchet wheel interruption to permit free rotation of the reel in the opposite direction for retrieval of the cables on the reel.

An improved battery jump cable apparatus for supplying electrical energy from the battery of a service vehicle to the battery of a second vehicle, comprising: a pair of jumper cables each having a clamp on a free end thereof for connecting the cables to the battery of the second vehicle; a casing mounted on the service vehicle; a reel disposed within the casing, the reel adapted for alternatively paying out and retrieving the jumper cables, the reel comprising: a frame; a spool having a spool axis about which the jumper cables can be wrapped on the spool, wherein the spool is mounted on the frame for rotation in opposed first and second directions about the spool axis, and wherein portions of each of said cables near one end thereof opposite said free ends are secured to the spool for wrapping the cable on the spool via rotation of the spool in the second direction; means for urging the spool to rotate in the second direction; a ratchet lock mounted on the frame for pivotation about an axis spaced from the spool axis and substantially parallel thereto, the ratchet lock having a protruding nose portion extending generally toward the spool axis in a neutral position of the ratchet lock; means for urging the ratchet lock toward the neutral position at such times that the ratchet lock is pivoted to either side of the neutral position; a ratchet wheel secured to the spool coaxially with the spool and in lateral alignment with the ratchet lock, the ratchet wheel having at least one first segment having a plurality of teeth formed thereon along an arc of a circle centered on the spool axis and intersected by the nose portion of the ratchet lock in the neutral position of the ratchet lock, and the ratchet wheel having at least one second segment of a radius insufficient for engagement of the second segment with the nose portion of the ratchet lock; and means for limiting the rotation of the spool so as to align the nose portion of the ratchet lock with portions of a second segment of the ratchet wheel at a limit of rotation of the spool in the first direction defined by the cables being fully paid out from said reel; a solenoid mounted on the casing, the solenoid having a set of normally open contacts and a coil energizable for closing said contacts, one side of said contacts electrically connected to one pole of the service battery; first connecting means for electrically connecting the other side of said solenoid contacts to one of said jumper cables at said reel; second connecting means for electrically connecting the other pole of the service battery to the other of said jumper cables at said reel; receiver means disposed within said casing for energizing the coil of the solenoid in response to reception by the receiver means of a coded electromagnetic signal at a preselected frequency; and a transmitter operable to transmit said coded signal of said preselected frequency.
