Stufenthermoschalter
Zusatz zum Patent 449179Step thermoswitch
Addendum to patent 449179

Patentiert im Deutschen Reiche vom 30. September 1927 ab
Das Hauptpatent hat angefangen am 17. Juli 1925.Patented in the German Empire on September 30, 1927
The main patent started on July 17, 1925.

Bei dem Stufenthermoschalter nach dem Hauptpatent war vorgeschlagen worden, in dem die Thermoschalter und den Heizdraht enthaltenden Gehäuse auch eine Wärmeschmelzsicherung zum Abschalten des ganzen Stromkreises oder eines Teiles desselben bei Übererwärmung anzuordnen.With the step thermoswitch after the Main patent had been proposed in which the thermal switch and the heating wire Containing housing also a thermal fuse to switch off the whole Circuit or a part of it to be arranged in the event of overheating.

Es hat sich beim Gebrauch derartiger Schalter herausgestellt, daß das genaue Einregulieren dieser Wärmeschmelzsicherung praktische Schwierigkeiten macht, die dadurch vermieden werden, daß man mindestens die .eine Stufe des Stufenthermoschalters' so ausbildet, daß sie ihren Stromzweig hei einer vorher bestimmten Höchsttemperatur abschaltet, was dadurch geschehen kann, daß man den Thermoschalter dieser Stufe in an sich bekannter Weise als einen auf die Temperatur ansprechenden,, mechanischen Selbstao ausschalter ausbildet.It has been found when using such switches that the precise balancing this thermal fuse makes practical difficulties which are avoided by having at least the . one step of the step thermoswitch is designed in such a way that that it switches off its current branch at a predetermined maximum temperature, which can be done by setting the thermal switch of this stage in a manner known per se as a temperature appealing, mechanical self-shutoff switch.

Die Zeichnung zeigt ein Ausführungsbeispiel, ι ist ein Stufenthermoschalter nach dem Hauptpatent. 2 ist ein Thermostreifen, der sich beim Erwärmen durchkrümmt und hierdurch den federnden Schalterteil 3 frei- 25 gibt, so daß bei 4 eine Momeatunterbrechung eintritt. Der Augenblick der Unterbrechung kann durch die Schraube 5 von außen reguliert werden.The drawing shows an embodiment, ι is a step thermoswitch according to the main patent. 2 is a thermal strip that bends when heated and this releases the resilient switch part 3, so that at 4 a torque interruption entry. The moment of interruption can be regulated externally by screw 5 will.

Die Art der Ausführung dieses Selbstausschalters ist im übrigen belanglos.The type of implementation of this automatic switch is inconsequential.
