Wooden box incorporating: rotating hand-crank on the right side; receiver and phone on the left side; on the front, pushbutton, two bells, and plate indicating the number of times to push the button to communicate with nearby telephones. Contains electrical circuits and a current generator operated by the hand-crank.
Installed in a railway station or crossing keeper’s booth, it was used to communicate with similar devices located nearby.
The nearby device was identified by a dot (brief pressure on the button) or dash (longer pressure) or a combination of dots and dashes. The caller pushed the button and then raised the telephone to communicate with only the specific apparatus called. If there was no power, the hand-crank could be turned to provide enough power for the short distance of the call.
