Patentirt im Deutschen Reiche vom 6. December 1878 ab.Patented in the German Empire on December 6, 1878.
Derselbe besteht aus zwei hohlen, elastischen, mit Wasser oder einer anderen Flüssigkeit gefüllten, dicht verschlossenen Körpern, deren einer dicht unter dem Dampfraum, der andere in der Nähe des vom Feuer direct berührten Kesselbleches an einem gleicharmigen Hebel hängen. Der obere Körper ist durch Doppelwandung, ausgefüllt mit schlechten Wärmeleitern, gegen die Wärme des unter ihm liegenden Wasserraumes geschützt und erhält durch den die Wärme gut leitenden oberen Boden die Temperatur des Dampfraumes, während der untere Körper in derselben Weise nur die Temperatur des Wassers und namentlich auch die der vom Feuer berührten Kesselbleche annimmt. So lange Wasserraum und Dampfraum dieselbe Temperatur haben, bleibt der Apparat in Ruhe, indem beide Körper sich gleichmäfsig ausdehnen. Tritt aber durch Siedeverzug oder durch Druckabnahme eine Differenz in der Temperatur beider Körper ein, so verändert sich die Gröfse derselben ungleichmäfsig, ebenso ihr specifisches Gewicht, infolge dessen sie eine entsprechende Veränderung in der Stellung des Hebels veranlassen. Ueberschreitet die Differenz ein durch Versuche festzustellendes Mafs, so öffnet der Hebel eine Dampfpfeife. Der mit dem Hebel verbundene Zeiger bezeichnet auf einer Scala die der Stellung des Hebels entsprechende Gefahr bezw. Sicherheit des Dampfkesselbetriebes. Der Apparat signalisirt sowohl den bei einem beliebigen Atmosphärendrucke entstandenen, als auch den durch Druckabnahme infolge übermäfsigen Oeffhens eines Ventils oder Abkühlung des Dampfraumes oder sonstiger Ursachen entstandenen Siedeverzug.It consists of two hollow, elastic ones filled with water or another liquid, tightly closed bodies, one of which touched directly under the steam room, the other near that of the fire Hang the boiler plate on a lever with the same arm. The upper body is double-walled, filled with bad heat conductors, against the warmth of the water space below protected and maintains the temperature thanks to the top base, which conducts heat well of the vapor space, while the lower body, in the same way, only the temperature of the water and especially that of the boiler plates touched by the fire. So long the water and steam room have the same temperature, the appliance remains at rest, in that both bodies expand evenly. But occurs due to delayed boiling or a decrease in pressure If there is a difference in the temperature of the two bodies, its size changes unevenly, as is its specific gravity, as a result of which it has a corresponding Change the position of the lever. If the difference exceeds a through When trying to determine the measure, the lever opens a steam whistle. The one with the lever Connected pointer indicates the danger corresponding to the position of the lever on a scale respectively Safety of the steam boiler operation. The device signals both the one any atmospheric pressures, as well as those caused by a decrease in pressure as a result of excessive Opening of a valve or cooling of the steam space or other causes resulting delayed boiling.
