[Shop-talk] old battery charger, how it works?

[Skip Albright]

I have a mid 30's battery charger and I cant understand how it works.

It has 120Volt AC going in.

Inside is a transformer with several different wires coming off the 
windings, I assume these are for different voltages.

It has a rotary switch, like the channel changer on your fathers TV. 
different amperages?

a couple of glass plug fuses in holders.

and a light bulb that screws into a regular light bulb base. (GE 189048)

How does it make DC?  or does it?

Thanks

Skip
