Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der Gegenstand des Patentes 131059 ^er Kl. 31 ist eine Vorrichtung zum Schmelzen von Legirungen oder leicht schmelzbaren Metallen und Giefsen derselben unter Druck, bei welcher die der Abnutzung sehr unterworfenen Theile auswechselbar angeordnet sind, so z. B. auch die in dem Schmelztiegel angebrachte Ausfütterung 2, in welcher der Druckkolben geführt ist. Statt dieser Ausfütterung ist nun nach vorliegender Erfindung der Kolben selbst mit einer besonderen auswechselbaren Reibungsfläche versehen, zum Zwecke, diesen ebenfalls der Abnutzung sehr unterworfenen Theil der Vorrichtung auswechseln zu können.The subject of patent 131059 ^ er Class 31 is a device for melting alloys or easily meltable metals and casting them under pressure, in which they are very subject to wear Parts are arranged interchangeably, so z. B. also mounted in the crucible lining 2, in which the Plunger is guided. Instead of this lining is now according to the present invention the piston itself is provided with a special replaceable friction surface for The purpose is to replace this part of the device, which is also very subject to wear and tear to be able to.

Die beiliegende Zeichnung stellt den mit der Neuerung versehenen Drnckkolben im Schnitt dar.The accompanying drawing shows the new pressure piston in the Cut.

Der Kolben j>, und zwar derjenige Theil, welcher in steter reibender Berührung mit der Wandung des Schmelztiegels steht, wird aus Asbest oder einem anderen geeigneten Stoff oder Stoffgemisch hergestellt, welches geeignet ist, eine glatte und weiche Oberfläche des Kolbens und somit eine gute Abdichtung zwischen Kolben und Tiegel herbeizuführen. Hierdurch wird eine Auswechselung der abgenutzten Theile der Schmelzvorrichtung oder eine Ausbesserung derselben sehr vereinfacht und erleichtert.The piston j>, namely that part which is in constant rubbing contact with the wall of the crucible is turned off Asbestos or another suitable substance or mixture of substances produced which is suitable is, a smooth and soft surface of the piston and thus a good seal between the flask and the crucible. This will result in a replacement of the worn out ones Parts of the melting device or a repair of the same are very simplified and relieved.

Das Asbest oder ein anderer in seiner Wirkung ähnlicher Stoff wird in Form von über einander liegenden Scheiben r auf eine Spindel oder auf einen Bolzen s gelegt und dieser vermittelst Gewinde/ in den am unteren Ende ebenfalls mit Innengewinde q versehenen Kolbenkörper ρ eingeschraubt, wobei dann der Kopf t der Spindel s die Dichtungsscheiben r zusammenprefst. Wie ersichtlich, können die schadhaft gewordenen Scheiben leicht und schnell ausgewechselt werden.The asbestos or another substance with a similar effect is placed in the form of disks r lying on top of one another on a spindle or on a bolt s and this is screwed into the piston body ρ , which is also provided with an internal thread q at the lower end, in which case the Head t of the spindle s presses the sealing washers r together. As can be seen, the damaged panes can be replaced quickly and easily.
