Description: | Railway telegraph receiver. Breguet Brevet , S.G.D.G. No. 42257 on mahogany base. Operates using a mechanism similar to a mechanical clock only the escapement is controlled by a relay that allows one 'tick' for every pulse received. The hand sweeps over the alphabetic face only in a clockwise motion, pausing at the letters of the message in synchronism with the hand of the sender. At the end of each word the hand should be returned to the top position. If it fails to do so the operator can reset it using the white front button. | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1865-1890 | Source: | University of Aberdeen | Creator: | Breguet | Identifier: | http://calms.abdn.ac.uk/Geology/dserve.e... | Go to resource |
