 EMI2.1 
 



   Wenn das Gespräch beendnet ist und der Hörer aufgehängt wird, geht noch immer Strom von der Batterie 41 durch den Magneten 33 über Haltekontakt 34'zur Erde, obwohl der Kontakt   21   einstweilen den Strom durch den Kontakt M unterbrochen hatte ; daher wird der   Anker : Jlnoch   immer vom Magneten. 33 festgehalten ; beim Herausnehmen des Anrufstöpsels 100 wird der Kontakt   4   durch Aberregung des Relais 9 wieder vorübergehend geschlossen. Dadurch wird der Generator 1 vorübergehend mit der Linie verbunden, so dass der   Magnet. 77   das Rad 39 um einen Schritt weiter drehen und dadurch den Kontakt 29 freigeben kann. Hiedurch wird der Stromweg durch die Klingel 22 unterbrochen, und da auch der Kontakt 48, 49 geöffnet bleibt, lässt das Trennrelais 52 seinen Anker los. 



   - Wenn der Teilnehmer das Amt anruft und der Haken 64 hochgeht, wird ein Stromkreis von der Batterie 41 aus durch Leitung 87, Linienrelais 80, Leitung 88,   Anker 5/,   Leitungen 89, 14, Mikrophon   undFemhörer des Teilnehmers, Leitungen 58, 15, 90, Anker 91 des Relais J2, Leitung 5J, Erdplatten 54,   55 und Leitungen 56, 57 geschlossen.

 mit der Zentralbatterie (41) verbunden wird.

 EMI2.1
 



   When the conversation is ended and the receiver is hung up, current still goes from the battery 41 through the magnet 33 via the holding contact 34 'to earth, although the contact 21 had temporarily interrupted the current through the contact M; therefore the anchor is always from the magnet. 33 held; When the call plug 100 is removed, the contact 4 is temporarily closed again by de-energizing the relay 9. This temporarily connects the generator 1 to the line, so that the magnet. 77 can turn wheel 39 one step further and thereby release contact 29. This interrupts the current path through the bell 22, and since the contact 48, 49 also remains open, the isolating relay 52 lets go of its armature.



   - When the subscriber calls the exchange and the hook 64 goes up, a circuit is started from the battery 41 through line 87, line relay 80, line 88, armature 5 /, lines 89, 14, microphone and remote receiver of the subscriber, lines 58, 15, 90, armature 91 of relay J2, line 5J, earth plates 54, 55 and lines 56, 57 closed.

 is connected to the central battery (41).

Claims (1)

2. Fernsprechsystem nach Anspruch 1, dadurch gekennzeichnet, dass das Einstecken des Anrufstöpsels (100) eine Elektrizitätsquelle (G) an das Schrittschaltwerk der Spiechstelle durch einen vorübergehend beeinflussten Kontakt (4, 5) anschaltet, der wieder beeinflusst wird, wenn der Stöpsel (100) nachher herausgenommen wird, wodurch die Verbindung wieder unterbrochen wird. EMI2.3 EMI2.4 2. Telephone system according to claim 1, characterized in that the insertion of the call plug (100) switches on a source of electricity (G) to the step-by-step switch of the Spiechstelle through a temporarily influenced contact (4, 5) which is influenced again when the plug (100 ) is removed afterwards, whereby the connection is interrupted again.
