Antique Telephones
I have three antique telephones. These telephones work. I have connected
two of the telephones together, connected each up to a dc power supply and talked
between both of them. And yes, the bells ring when the magneto crank on either
is turned.
Below is a candlestick phone and its associated ringer box. This phone was
manufactured by Kellog Switchboard Supply of Chicago. The magneto in the
ringer box had been replaced, but it is functional. However the coil
for the transmission network had a broken winding where the magneto had
apparantly hit it. I was able to repair it to make the phone functional. The
telephone itself had no hookswitch, so I purchased a replacement that I had to
modify to make it compatible with this telephone. After all of this, the
telephone works now. The cosmetics of this telephone are not the best with
rust on the candlestick and a chip out of the mouthpiece, but it is a nice
old working telephone.
Below is a pciture of the inside of the ringer box for the candlestick telephone.
Below is a picture of the electrical schematic inside the ringer box.
Below is a wall-mounted telephone from the same era as the candlestick telephone
shown above. This wall-mounted telephone was manufactured by Western Electric and is a Model 317AH.
The telephone requires three dry cell batteries. This telephone is is excellent condition except for the cord for the earpiece.
However, only the outer covering of this cord is frayed - the inner two conductors
are not frayed. This telephone worked when I received it.
