Abstract

367,005. Railway signalling apparatus. HAHN, O., 36, Gereonshof, Cologne, Germany. Nov. 5, 1930, No. 33299. Convention date, April 30. [Class 105.] A siren c for the protection of section gangs is switched into action when a circuit extending to a distant control point is broken or, alternatively, closed either manually or by the action of a train, and the siren when in action sends a repeat or return indication to the control point by current of a different character. For instance, an interrupter e on the siren wheel d provides current impulses to a primary winding of a transformer g, the secondary of which provides alternating current to flash a gaseous conduction lamp f at the distant control point.
