Yesterday The set of coils, I bought a few weeks ago on Ebay, arrived. Between them there are two not model T coils. I wonder where they were used for, how to connect them, should they be set up as the model T coils, do they have any value or are they just collecting items?
Shall they be set up on a HTTC?
One say "Detroit Coil Company". In the front there are two connection with the inscriptions Plug and Com. Stand this for Spark plug and Commutator?? On the top there is a third connection near to the contact points with no inscription. Could this be the battery connection.
The second is black but I can't read the inscriptions.
On the front are three connections, one say B, the second T and the third S.
On the back there are two bolts to attach the coil to a frame I think.
Thanks for any information.
Photos in the attachment.
Those are for an electric fence. Used to keep cows from tearing down fences.
but I don't believe it is for cows.
If you let a coil buss for an hour the black stuff inside will get that hot it will just come out of the coil.
Andre, the coil for an electric fence doesn't fire continuously, there is usually an intermittent switch that energizes the fence every couple of seconds or so.
The Detroit coils were used in Fairmont railroad track cars. They are still made today.
Trembler coils were used in many applications requiring a spark gap ignition. Some that come to mind are home oil fired heating plants, roofing tar heaters, Spark plug testers, WWII flame throwers and many others.
Here is a photo of a coil used as a fence charger.

"The second is black but I can't read the inscriptions.

I would suspect that B is for battery, T is for timer and S is for spark plug.
I think Royce is right.
When a local man was alive, he had a "modern" electric fence repair shop, but his personal shocker was a Model T coil just like the ones that we use.
He had a small motor with a momentary contact switch that activated the coil and energized the fence every few seconds. The motor and the coil ran off a 6v battery that had to be re-charged periodically.
Just for the heck of it I Googled "vintage model T electric fence charger" and I got many hits, including this Youtube video http://www.youtube.com/watch?v=vBBHuJiSY6c
Just for info.
I found the Fairmont use of the Detroit Coil.
