L.M. ERICSSON & Co wall telephone
 The date of invention of the telephone, a device capable of transmitting and receiving spoken words, is considered February 14, 1876. On the same day, four hours apart, two patent applications were filed with the New York Patent Office. The first application was made by Alexander Graham Bell and the second by Elisha Gray. For many years in a row, after the invention was introduced, there was a series of lawsuits between them, during which Bell had to prove his primacy.
In 1876, the famous Swedish telephone company Ericsson began its activities, when Lars Magnus Ericsson and his friend Karl Anderson founded the L.M. Ericsson and Co electromechanical workshop. This workshop initially repaired telephones and other signaling equipment, but in 1878 the production of self-designed telephones began. Ericsson opened its own production thanks to the telephones of the American Bell Telephone Company, which appeared on the Swedish market in 1877 and were often repaired. By repairing these phones, Ericsson was able to not only study their design, but significantly improve it. Ericsson devices were much more convenient, had better sound quality, and cost less than American devices. Gradually L.M. Ericsson & Co devices gained popularity not only in Sweden but also abroad. At the beginning of the 20th century, the Swedish company Ericsson opened its branch also in Russia.
The wall telephone shown in this display case is a model produced in 1907-1915 in St. Petersburg, Russian Empire. This is a phone that came into the possession of the National Museum of History of Moldova in 1984 by transfer from the State Museum of History and Local Lore. The exhibit is one of the rarities of great historical and scientific technical value.The telephone is mounted in a wooden case having the shape of a parallelepiped. Above the case, on a plate in the form of a truncated cone with wavy edges, five clamps are mounted for connecting telephone and grounding lines, a transmitter microphone and two bells. In the upper part of the case there is a compartment for the inductor, and in the lower part there is a battery compartment. The inductor handle is installed on the right. On the left, on a metal lever, is a receiver with an ebonite handle, connected to the device via a textile-coated cord. The phone was equipped with electromagnets. For use, it was necessary to pick up the receiver, turn the handle, which actuated the inductor that transmits the signal to the telephone exchange, where it was received by the telephone operator, who connected with the requested subscriber. This type of device was intended for railways. In 1917, this telephone was used at the Lipcani railway station in the Khotin Uyezd of the Bessarabia Governorate (now the Briceni district). The Ocniţa - Lipcani railway line was put into operation in 1893 along with two other lines of Mogilev - Ocnita and Bălți - Ocnita.
