11. Portable pointer telegraph

Siemens & Halske, Berlin 1947
In 1847, Werner Siemens (1816-1892) und Georg Halske (1814-1890) founded the Telegraphen-Bauanstalt von Siemens & Halske in Berlin. The first workshop was located in the immediate vicinity of todays Deutsches Technikmuseum. The companys founding was based on a technically improved version of the pointer telegraph
Siemens used a Wagners Hammer to synchronize the transmitting and receiving devices. This electromagnetic self-breaker is operated magnetically and works independently. When a letter key is pressed at the transmitting device, enough current pulses are automatically delivered until the pointer on the receiving device lands in the same position. Only one conductor wire was necessary for the transmission
The Siemens pointer telegraph was first utilized for the Berlin - Frankfurt a. M. railway line in 1848
