Welcome to the E-M-F Carbide Generator Restoration Page

So you want to how the restoration of the E & J Carbide Generator for my E-M-F Automobile is going? Well, you have found the right page.

The correct carbide (or acetylene) generator for the 1912 E-M-F is the E & J running board mounted generator. This page will follow the restoration of the generator for my 1912 Demi Tonneau.

I found the E & J Carbide Generator, last main piece of the E-M-F, on EBay in October of 2010. I did not plan to buy this item until I was closer to the end of the restoration of the car. But, a good deal (at least I thought so) came along so I jumped on it while I had the chance. I am glad I did. This is an original item which does not appear to have ever been used. The original basket is in side and the original running board mounting bracket was included.

As you can see from the pictures, there are only a couple of small dents to remove.

The way this works is that water (I will use distilled water) is put in the top tank. Calcium Carbide crystals are placed into the basket. When the unit is closed up and the water valve on the side of the unit is opened, water will drip onto the Calcium Carbide and release Acetylene gas which is piped to the burners in the headlights. I have read that there is approximately 5 PSI of pressure. The waste product from this procedure will corrode metal so the generator must be cleaned after each use.

I was not sure if this was an original or a reproduction generator which had been allowed to tarnish. I posted a message on the AACA discussion forum asking some of the more experienced readers there for an opinion. Everyone agreed that it was original and I was fortunate to find it.

I will be cleaning this up in the future which will involve cleaning the old tarnish off of it, polishing up the brass and fixing any dents. It does not appear to be cracked anywhere which is unusual.

Stay tuned for future updates. Happy Motoring!
