IGNITION COIL OF FORD MODEL" "LOOSE COUPLER TRANSFORMER, wireless coillection, spark-gap wireless transmitter, wireless high voltage coil, Ford T ignition coilT" Automobile,

IGNITION COIL OF FORD "MODEL"T" Automobile.

It was one of 4 plug-in coils in a wood box, which ignited the 4 cylinders engine. 

At the beginning of the 20th century, experimenters and hobbyists have built home-made Wireless Telegraph spark-gap transmitters from parts that were available at specialized stores.

 

The FORD T ignition coil was used by many for supplying the high voltage pulses to the spark gap circuit.

 

The picture at the right shows an example of amateur wireless telegraph spark-gap transmitter of those days.
