E67 German Eiserner Armeefernsprecher, 1913

Описание: Visit http://fieldphones.org/episode67/ for additional information.

The "Eiserner Armeefernsprecher" is the 1913 successor to the original 1905 "Armeefernsprecher", later referred to as the "Armeefernsprecher alter Art" ("Army Telephone, Old Type"). The electrical setup and functionality remain identical to the 1905 model, but the 1913 version is constructed from painted sheet metal instead of aluminum. Additionally, the talk switch has been modified from a wooden button integrated into the handle to a wooden lever on the side, which can be held in position.

The "Armeefernsprecher" itself is designed solely for buzzer signaling. To enable compatibility with ringer systems and field switchboards other than the "Summerschauzeichenschrank" (buzzer switchboard), an auxiliary box known as the "Zusatzkasten" was developed. This auxiliary unit includes a hook switch, a magneto, and a ringer. There were two versions of the "Zusatzkasten": an older model with switching sockets for single-wire connections with earth return, and a newer version with two-wire switching sockets. The model presented here is the newer version, also referred to as the "Zusatzkasten neuer Art" ("New Type Auxiliary Box").
