Hello everybody, I thought I would start a new project. In this world of fancy cell phones and what not, I thought it would be a fun project to take my old telephone and get it up and working again. It is a 1907 hand crank wall telephone. It has 3 terminals at the top, and when I connected a makeshift telephone wire to it, I got a dial tone! I could even receive calls, and when I turned the crank, the rotary dial phone on the other side of my house would ring! Unfortunately, the ringer won't work when someone calls, and nobody can hear me. I don't think I am connecting it 100% correctly. Images of the telephone can be found at the following link:

The second image is of the inner workings of the phone, and the third image is the wire I hooked up to it. The last image is of the rotary dial phone that I was taking about (also very old- from the 1920s, but the newest phone that I own :) ). I figure that if the old rotary dial phone can work on the modern lines, the crank one might could too. I know that with the hand crank phone, I cannot make a call, but I would like to be able to receive calls successfully. I would also like to be able to use it without modifying it dramatically (without installing new parts and components). I know that this website is mostly for modern technologies, but I am not a member of any other organization with such a wealth of knowledge, and any help from anyone would be greatly appreciated. Thank you very much for your help, and have a happy Thanksgiving to all!

First:

Second:

Ringer may not work because: 1) may no longer be wired correctly and/or 2) your current telephone line does not have enough power.

Third: For a one telephone line (one phone number) your land line service is probably using the green (tip) and red (ring) pair. Those are the two wires you will need to connect into the old phone to talk and listen provided the mouthpiece and earpiece each work. Lots of documentation on line about standard home telephone wiring.

FOURTH: Do not use the crank to ring - disable it electrically by removing the wiring. Puts out quite an electrical jolt and who knows what damage that may cause somewhere along the way. Especially to any modern telephone line items: faxes, security, DSL connections. All digital anyway.....

Read up on your telephone service provider's rules regarding what is permitted to be connected. Generally they are responsible for connectivity up to the entry connection to your house. You are responsible for anything thereafter. However, you may be liable if something you connect causes damage or loss of service somewhere else.

Hi, thank you very much for the advice and the schematics. I will also look into disabling the magneto; I would sure hate to blow up a modem or anything. Thanks again, and Happy Thanksgiving.
