  Heizrollensicherung für Fernsprechanlagen oder andere Schwachstromleitungen. 



   Bei der Sicherung nach dem Patente Nr. 44737 ist es nötig, um die Sicherung nach ihrer Funktionierung wieder gebrauchsfähig zu machen, sie mittels eines Handgriffes in ihrem Halter bei gleichzeitigem Anspannen der Feder umzukehren. 
 EMI1.1 
 bei welcher der die Kontaktgabe des zusätzlichen Stromes bewirkende Körper dazu benützt wird, die beweglichen Teile der Sicherung in ihre Ruhelage zurückzuführen. In der Zeichnung ist eine solche Ausführungsform der Sicherungseinrichtung dargestellt, bei welcher die den Zustzstrom führonde Kontaktfeder g' auf der andern Seite des Sicherungshalters a als die in den zu sichernden Stromkreis eingeschaltete Kontaktfeder e angeordnet ist.

   Der bewegliche Teil c'der Sicherung ist als doppelarmiger Hebel ausgebildet, hinter dessen oberes Ende der Feder e mit einer hakenförmigen Umbiegung u derart greift, dass sie nach Schmelzen des Lotes die Drehung dieses Teiles veranlasst, bis sie schliesslich bei einer gewissen Schräglage abspringt. Nach einer kurzen Bewegung des Sicherungsteiles c'trifft dessen untere Hälfte gegen die Kontaktfeder   ',   so dass der über die Heizrolle fliessende Zusatzstrom zustande kommt. Die Feder g' ist so stark bemessen. dass sie nach dem Abspringen der Kontaktfeder e den Sicherungsteil c'in seine Anfangslage zurückdrückt, so dass durch erneutes Überhaken der Feder e die Sicherung wieder in Bereitschaft gesetzt werden kann.

   Damit dabei der Zusatzstrom unterbrochen wird, ist die Feder e mit einem isolierten Ansatz   v   versehen, der gegen die Feder go trifft und diese etwas   zurückdrückt.

  Heating roller protection for telephone systems or other low-voltage lines.



   With the fuse according to patent no. 44737, in order to make the fuse usable again after its functioning, it is necessary to reverse it by means of a handle in its holder while tensioning the spring.
 EMI1.1
 in which the body causing the contact of the additional current is used to return the moving parts of the fuse to their rest position. The drawing shows such an embodiment of the safety device in which the contact spring g 'carrying the additional current is arranged on the other side of the fuse holder a than the contact spring e connected to the circuit to be protected.

   The movable part c'der fuse is designed as a double-armed lever, behind the upper end of which the spring e engages with a hook-shaped bend u in such a way that it causes this part to rotate after the solder has melted until it finally jumps off at a certain incline. After a short movement of the securing part c ', its lower half hits the contact spring', so that the additional current flowing over the heating roller comes about. The spring g 'is dimensioned so strong. that after the contact spring e has jumped off, it pushes the securing part c 'back into its initial position, so that the securing device can be set to readiness again by hooking over the spring e again.

   So that the additional current is interrupted, the spring e is provided with an insulated extension v, which strikes against the spring go and pushes it back somewhat.
