The opening sentence of this patent application states: "This invention relates to a system of telephony by which the same communication can be made from one transmitter station simultaneously to any desired number of receiver stations, by a reader or telephone continually repeating for a certain time into his transmitter a series of news and after the lapse of this time proceeding in the same manner with the latest news, and so on, so that during the time of the news service the entire telephonic system will so to speak be continuously traversed by news, and each subscriber has only to use his receiver in order to be at any time supplied with the latest news which he listens to, for instance until he hears a repetition commence, whereupon he hangs up the receiver and listens again only when the communication of a fresh series of news begins."

Telephonic News Dispenser
Theodor Puskas, Budapest, Hungary, 5th September, 1893; 6 years.

    Claim.--1st. A telephonic system for making communications from a central telephone station simultaneously to any desired number of receiver stations, in which, for the purpose of obtaining uniformity in the strength of sound at each receiver station, and protecting each receiver station against disturbances from all the other receiver stations, the receiver of each of the said receiver stations is operated by the currents of the secondary winding of an induction coil which supplies this receiver station exclusively with the currents of its secondary windings, substantially as desired. 2nd. A constructional form of the system for making communication from a central telephone station simultaneously to any desired number of receiver stations as described in which receivers are served by one induction coil, substantially as described. 3rd. A constructional form of the telephonic system for making communications from a central telephone station simultaneously to any desired number of receiver stations as described in which the secondary windings of the induction coils, the currents of which operate the receivers of each of the receiver stations are included in the earth conductors or between the outgoing and return conductors of a telephonic system serving for the intermediate service, substantially as described. 4th. A constructional form of the telephonic system for making communications from a central telephonic station simultaneously to any desired number of receiver stations as described in which the receiver coils are arranged at the subscriber's places or in their vicinity, substantially as described.
