  Selbsttätiger Stromunterbrecher für elektrische Heizapparate, insbesondere 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 der Kontaktfeder 22 zu verhindern, ist unter dem   Arm-M   ein Grenzstift 29 in der Deckelplatte 1 eingeschraubt. 



   Die   Betätigung   des Ausschalters geschieht bei der Erwärmung des Apparates durch den durch den Widerstandskörper 2 hindurchgehenden elektrischen Strom, bei der auch die Zweimetallschiene 8 erwärmt wird. Bei dieser Schiene bildet das Metall von   grösseler     Ausdehnungsfähigkeit   den oberen Teil. 



  Die Schiene biegt sich infolgedessen bei der Erwärmung nach unten, so dass der Stift 10 sich abwärts bewegt. Hat die Feder 15 ihren Halt auf dem Stift verloren, so schnellt unter Einwirkung der Feder 16 der   Arm-M nach   oben, wodurch der Kontakt zwischen dem Streifen 17 und der Feder 22 plötzlich gelöst und der Heizstrom unterbrochen wird. 



   Um nun den Zeitpunkt des Ausschaltens des Stromes innerhalb gewisser Grenzen verändern zu können, ist zwischen der Befestigungsstelle der Schiene 8 und der Kammer 6 eine kurze, quer unterhalb der Schiene 8 angeordnete Welle 30 gelagert, die an der unter der Schiene 8 liegenden Stelle eine exzentrische Eindrehung 26 besitzt, welche gestattet, bei einer Drehung der Welle die Schiene 8 etwas anzuheben und dadurch auch den Stift 10 etwas höher zu stellen, so dass die Auslösung der Feder 15 verzögert wird. 



  Um die   Welle.'30 nach   Bedarf einstellen zu können, besitzt sie einen   Handhebel j'l,   der bis zu einem An- 
 EMI2.1 
 sein, welche gestattet, die jeweilige Stellung der Welle abzulesen. 



     PATENT-ANSPRÜCHE   :
1. Selbsttätiger Stromunterbrecher für elektrische Heizapparate, insbesondere   Vulkanisiervorneh-   tungen, mit an dem einen Ende eingespannter   Zweimetalhchiene, dadurch gekennzeichnet,   dass die Zwei- 
 EMI2.2 
 Blattfeder   (15)   angeordnet ist, die bei dem zufolge der Erwärmung auftretenden Ausbiegen der Zweimetallschiene und dem dadurch verursachten Ausweichen des Stiftes (10) frei wird, so dass der Schaltann   (1.'3,   17) unter der Einwirkung einer Feder   (16)   in die Ausschaltstellung gelangt.

  Automatic circuit breaker for electric heating apparatus, in particular
 EMI1.1
 

 <Desc / Clms Page number 2>

 To prevent the contact spring 22, a limit pin 29 is screwed into the cover plate 1 under the arm-M.



   The switch is actuated when the apparatus is heated by the electric current passing through the resistance body 2, during which the bimetal rail 8 is also heated. The upper part of this rail is made of metal of greater expandability.



  As a result, the rail bends downward when heated, so that the pin 10 moves downward. If the spring 15 has lost its grip on the pin, then under the action of the spring 16 the arm-M snaps upwards, whereby the contact between the strip 17 and the spring 22 is suddenly released and the heating current is interrupted.



   In order to be able to change the time at which the current is switched off within certain limits, a short shaft 30, arranged transversely below the rail 8, is mounted between the fastening point of the rail 8 and the chamber 6 Has a recess 26 which allows the rail 8 to be raised slightly when the shaft is rotated and thereby also to raise the pin 10 slightly so that the release of the spring 15 is delayed.



  In order to be able to adjust the Welle.'30 as required, it has a hand lever j'l, which can be
 EMI2.1
 which allows the respective position of the shaft to be read.



     PATENT CLAIMS:
1. Automatic circuit breaker for electrical heating devices, in particular Vulkanisiervorneh- tungen, with two-metal rail clamped at one end, characterized in that the two-
 EMI2.2
 Leaf spring (15) is arranged, which becomes free when the bimetal rail is bent and the pin (10) deflects as a result of the heating, so that the switch (1.'3, 17) is under the action of a spring (16) reaches the switch-off position.

 

Claims (1)

2. Stromunterbrecher nach Anspruch l, dadurch gekennzeichnet, dass zwecks Änderung des Zeit- EMI2.3 schiene (8) veränderbar i3t, so dass die Länge des über die Kante der Blattfeder (15) greifenden Stiftteiles entsprechend vergrössert oder verringert werden kann. 2. Circuit breaker according to claim l, characterized in that for the purpose of changing the time EMI2.3 The rail (8) can be changed so that the length of the pin part reaching over the edge of the leaf spring (15) can be increased or decreased accordingly.
