   Der Zweck der vorliegenden Erfindung ist, bestehende   Haustelegraphenloitungen   zugleich als Telephonloitungen zu benutzen. Da die bestehenden Leitungen   Verwendung nnden,   so wird dieser Zweck mit sehr geringen Mitteln erreicht. Zu jeder aus einem Zimmer zum Indikatortableau fuhrenden Leitung wird in unmittelbarer Nähe des   Tasterknopfes   ein einfacher Hakooumschalter mit einem   Mikrotelephon   hinzugefügt und beim Indikatortableau wird ebenfalls ein   Mikrotelephon   und ein Hakenumschalter angebracht. 



   In der umstehenden Zeichnung ist der Erfindungsgegenstand in einem Schema dar-   gestellt : 1, 2,   3 stellen die Taster vor. welche sich in verschiedenen Zimmern befinden.

   The purpose of the present invention is to use existing house telegraph lines as telephone lines at the same time. Since the existing lines are in use, this purpose is achieved with very few resources. For each line leading from a room to the indicator panel, a simple Hakoo switch with a microtelephon is added in the immediate vicinity of the push button, and a microtelephone and a hook switch are also attached to the indicator panel.



   The subject of the invention is shown in a scheme in the drawing below: 1, 2, 3 represent the buttons. which are in different rooms.

 Likewise, a line goes from the drop flap II via 11, 36, 17, 18, 41, 37 to 12 to the button 2. Are jodoch z. B. the microtelephones; 23 and 2S lifted off, the circuit from 7 ül) closes via 4, 45, 2S, 29, 48, 43, 14, 39, 42, 21, 49, 25, 32, 33, 24 ,. 5) and 51 and the Mikrotclephom'23 and 28 are connected in series with the battery 7 alone,

Claims

PATENT CLAIM: Circuit arrangement for combined house telegraph and telephone systems, in which a normally closed interruption part is switched on in each of the circuits that actuate the drop flaps and the bell, these interruption points being opened by a contact body (21) attached to a contact slide connected to the telephone set of the central office is arranged and when it is operated EMI1.6 both interrupts the associated indicator circuit and connects the telephone set of the central office to the room line separated from the drop flap, thereby EMI1.7 is designed for the telephone set of the central office,

so that after the slide has been moved, the indicator circuit is interrupted and the speech line is closed automatically when the central unit's telephone set is lifted off the hook. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
