Description

Löschkammer aus Hartpapier In dem Patent 522 037 ist eine Löschkammer aus Hartpapier beschrieben, bei der besondere Maßnahmen zur Erhöhung der Festigkeit getroffen sind. Man kann nach der Erfindung die Löschkammer in der gleichen Richtung noch weiter vervollkommnen, wenn man den Boden nicht aus einem flachen Hartpapierstück herstellt, sondern ihn durch Pressen oder in beliebiger anderer Weise nach innen wölbt: Die Wirkung ist natürlich am größten, wenn jede einzelne Papierlage selbst auch gewölbt ist.Erase chamber made of hard paper Patent 522 037 describes an erase chamber made of hard paper in which special measures are taken to increase the strength. According to the invention, the extinguishing chamber can be improved even further in the same direction if the bottom is not made from a flat piece of hard paper, but rather arches inwards by pressing or in any other way: the effect is of course greatest when each individual layer of paper itself is also arched.

Das Pressen führt man am zweckmäßigsten vor dem Fertigbacken aus, solange die Hartpapiermasse noch gewissermaßen plastisch ist. Durch das Überführen des Klebestoffes in den unlöslichen und unschmelzbaren Zustand, im Anschluß an das Pressen oder gleichzeitig damit, erhält man dann eine sehr feste, starre Kugelschale,. die den in der Löschkammer entstehenden Druck nach Art eines Gewölbes aufnimmt.It is best to carry out the pressing before the final baking, as long as the hard paper pulp is still plastic to a certain extent. By transferring of the adhesive in the insoluble and infusible state, following the Pressing or at the same time, you get a very solid, rigid spherical shell. which absorbs the pressure created in the extinguishing chamber in the manner of a vault.

In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. In Abb. z ist a das untere Ende eines Löschkammerzylinders ausHartpapier, dessen Rand zur Aufnahme des Bodens konisch gepreßt ist. Dieser Boden b ist nun selbst in dem Sinne gewölbt gepreßt, daß seine Druckfestigkeit gegenüber der von oben auf ihn wirkenden Beanspruchung erhöht ist. Um die bei c entstehenden Winkel, in denen sich Schmutz und Ölschlamm ansammeln kann, zu vermeiden, kann man nach Abb. 2 die obere gewölbte Fläche flach oder trichterförmig nachdrehen.Two exemplary embodiments of the invention are shown in the drawing. In Fig. Z, a is the lower end of an arcing chamber cylinder made of hard paper Edge is pressed conically to accommodate the bottom. This floor b is now itself arched in the sense that its compressive strength compared to that from above acting on him is increased. To the angles arising at c in which To avoid the accumulation of dirt and oil sludge, see Fig. 2 the Turn the upper curved surface flat or funnel-shaped.
