Patentirt im Deutschen Reiche vom 20. Juli 1877 ab.Patented in the German Empire on July 20, 1877.
Die Zeichnung zeigt in Fig. 1: A den Schaft der Schraube, α den Kopf derselben, χ χ eine schräge Fläche bezw. Schale am Untertheil des Kopfes a; mm zeigt die zur Dichtung des Dampfes, Luft oder Wasser, verwendete Verpackung, B und C zeigen zwei Kesselwandungen, die durch vorbenannte Schraube verbunden sind, b die hierzu verwendete Mutter. Fig. 2 zeigt die Schraube von oben, die hier rund, aber in jeder Kopfform hergestellt werden kann.The drawing shows in Fig. 1: A the shaft of the screw, α the head of the same, χ χ an inclined surface or. Bowl on the lower part of the head a; mm shows the packaging used to seal the steam, air or water, B and C show two boiler walls connected by the aforementioned screw, b the nut used for this purpose. Fig. 2 shows the screw from above, which can be made here round, but in any head shape.
Der Werth dieser Schraube im Gegensatz zu den bis jetzt gebräuchlichen, besteht darin: Beim Gebrauch derselben wird die Verpackung»??» infolge der schrägen Fläche χ χ des Unterkopfes an den Schaft der Schraube gedrängt; dem Dampfe, Wasser oder der Luft, ist keine Fläche zum Zerstören geboten, man erhält Dichtung, und zwar auf langer Dauer, . auf den unebensten Flächen. Die Wirkung der Schraube wird eine efhöhtere, sobald durch Druck oder Wärme eine Expansion der Metalle eintritt. Bei den bis jetzt zu Dichtungen angewendeten Schrauben ist die Wirkung im Werth zu der oben angeführten eine entgegengesetzte; denn je stärker der Druck oder Anspannung derselben, je mehr wird die Verpackung vom Schaft der Schraube fortgedrängt und in kürzester Zeit ist wieder Undichtigkeit vorhanden.The value of this screw, in contrast to the ones that have been used up to now, is as follows: When using the same, the packaging "??" due to the inclined surface χ χ of the lower head pressed against the shaft of the screw; Steam, water or air have no surface to destroy, one obtains a seal, and that for a long time. on the most uneven surfaces. The effect of the screw increases as soon as the metals expand due to pressure or heat. In the case of the screws hitherto used for seals, the effect is opposite in value to that given above; because the stronger the pressure or tension of the same, the more the packaging is pushed away from the shaft of the screw and the leakage is again present in a very short time.
Wenn der Vortheil der Anwendung dieser Schraube gegen die bis jetzt gebräuchlichen ein scheinbar geringer ist, so ist derselbe im praktischen Gebrauch ein bedeutender, hauptsächlich bei grofsen Anlagen, wie Zuckerfabriken u. a. m., wo die Arbeit ununterbrochen fortgehen soll.If the advantage of using this screw is against the one that has been used up to now is apparently less, in practical use it is an important one, mainly in the case of large plants such as sugar factories and others. m. where the work should continue uninterrupted.
