  Vorrichtung zum Einschalten von Nebenstationen bei   Telephonapparaten.   
 EMI1.1 
 der Fig.   1.   Die Fig. 4 und 5 veranschaulichen die einzelnen Verbindungen in den beiden Stellungen. 



   Die Vorrichtung besteht aus einer Walze a, an der ein Arm b mit einem Gewicht c am Ende befestigt ist. Auf dieser Walze sind die   Kontakte I, II, III   für die   Hauptleitung 7 sowie   die Zuleitungen 2 bezw. 3 zur   Haupt- und Nebenstation angeschlos8en   und sebleifen auf denselben die Kontaktfedern   du, dz   Die Walze a trägt ferner einen Stift e, durch den mit Hilfe eines 
 EMI1.2 
 die Kontakte II und   III,   die in verschiedenen parallelen Ebenen sich befinden, auf der Walze a um 900 versetzt sind. Jeder dieser Kontakte II und   III   ist mit dem Kontakt I leitend verbunden. 
 EMI1.3

 der Nebenstation gesprochen wird.

   Wird an der Hauptstation gesprochen und will sich die Nebenstation einschalten, so merkt erstere dies an dem Fallen des Armes und schaltet sich durch Heben des Armes wieder ein, so dass die Nebenstation, dadurch, dass sie keine Verbindung bekommt, merkt, dass von der Hauptstation gesprochen wird. 



   PATENT-ANSPRÜCHE : 
1. Einrichtung zur Einschaltung von Nebenstationen bei Telephonapparaten, gekennzeichnet durch eine Kontaktwalze mit Kontakten für die Stromzuleitung und die Anschlüsse zur Haupt-und Nebenstation, welche Walze durch einen belasteten Arm so verdreht werden kann, dass der Anschluss der Hauptstation aus-und jener der Nebenstation eingeschaltet werden kann, wobei die Walze in der Einschaltstellung der Hauptstation durch einen Sperrstift gehalten wird.

  Device for switching on secondary stations in telephone sets.
 EMI1.1
 1. FIGS. 4 and 5 illustrate the individual connections in the two positions.



   The device consists of a roller a to which an arm b with a weight c is attached at the end. On this roller, the contacts I, II, III for the main line 7 and the leads 2 respectively. 3 are connected to the main and secondary station and the contact springs du, dz drag on the same. The roller a also carries a pin e through which with the help of a
 EMI1.2
 contacts II and III, which are located in different parallel planes, are offset by 900 on roller a. Each of these contacts II and III is conductively connected to contact I.
 EMI1.3

 the substation is spoken.

   If someone speaks at the main station and wants to switch on the slave station, the former notices this by the fall of the arm and switches on again by lifting the arm, so that the slave station notices that from the main station by not getting a connection is spoken.



   PATENT CLAIMS:
1. Device for switching on secondary stations in telephone sets, characterized by a contact roller with contacts for the power supply and the connections to the main and secondary station, which roller can be rotated by a loaded arm so that the connection of the main station and that of the secondary station can be switched on, the roller being held in the switched-on position of the main station by a locking pin.

Claims (1)

2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass der die Walze haltende Sperrstift sich an dem Anker eines Elektromagneten befindet, dessen Stromkreis von der Nebenstation geschlossen werden kann, so dass die Nebenstation die Freigabe des Armes zur Umschaltung bewirken kann. 2. Device according to claim 1, characterized in that the locking pin holding the roller is located on the armature of an electromagnet whose circuit can be closed by the secondary station so that the secondary station can release the arm for switching.
