Zusatz zum Patente No. 52650 vom 3. December 1889.Addendum to patent no. 52650 of December 3, 1889.
Patentirt im Deutschen Reiche vom 26. Februar 1891 ab. Längste Dauer: 2. December 1904.Patented in the German Empire on February 26, 1891. Longest duration: December 2, 1904.
Nach dem Haupt-Patent findet die Vornahme der Schmelzung sowohl als des Gusses gemeinsam im luftverdünnten Raum durch Anordnung eines elektrischen Schmelzofens und der erforderlichen Giefsvorrichtungen und Formen in einem Behälter A statt, aus welchem während des Schmelzern und Giefsens die Luft entfernt wird.According to the main patent, the melting and casting are carried out jointly in the air-diluted space by placing an electric furnace and the necessary casting devices and molds in a container A , from which the air is removed during the melting and casting.
Es hat diese Anordnung den Nachtheil schwerer Zugängigkeit und macht überdies eine verhä'ltnifsmäfsig grofse Anzahl luftdicht verschliefsbarer Oeffnungen erforderlich.This arrangement has the disadvantage of difficult access and, moreover, makes one A relatively large number of openings that can be hermetically sealed are required.
Diese Uebelstände zu beseitigen, ist der vorliegende Apparat bestimmt, welcher auf beiliegender Zeichnung in Fig. 1 in Vorderansicht, Fig. 2 in einem Verticalschnitt nach der gebrochenen Linie A-B, Fig. 3 in Seitenansicht und Fig. 4 im Grundrifs dargestellt ist.The present apparatus is intended to eliminate these inconveniences, which is shown in the accompanying drawing in FIG. 1 in a front view, FIG. 2 in a vertical section along the broken line AB, FIG. 3 in side view and FIG. 4 in outline.
Wie ersichtlich, ist der Behälter A des Haupt-Patentes gänzlich in Wegfall gelangt und bildet während des Schmelz- bezw. Giefsprocesses der Schmelzofen mit den Gufsformen ein luftdicht abgeschlossenes Ganzes, dessen Einzeltheile von aufsen überall bequem zugängig sind und leicht gehandhabt werden können..As can be seen, the container A of the main patent has completely disappeared and forms during the melting or. The casting process of the melting furnace with the casting molds creates an airtight whole, the individual parts of which are easily accessible from the outside and can be easily handled.
Da die Schmelzung von Metallen im Ofen O auf elektrischem Wege erfolgt, so ist der Ofen in den Stromkreis einer Dynamomaschine eingeschaltet. Unter Anwendung von Elektroden aus dem gleichen Metall wie das zu schmelzende oder aus einem schwerer schmelzbaren Metall wird der elektrische Strom unmittelbar durch das zu schmelzende Metall hindurchgeleitet. Letzteres wird in granulirtem Zustande angewendet. Die hierdurch erzeugten Contactwiderstände ermöglichen die Concentration der Entwickelung der Stromwärme innerhalb des zu schmelzenden Metalles., EE1 sind die an den Schmalwänden des Ofens angeordneten plattenförmigen Elektroden, welche mit den +-Since the melting of metals in the furnace O takes place electrically, the furnace is connected to the circuit of a dynamo. Using electrodes made of the same metal as the metal to be melted or made of a more difficult-to-melt metal, the electrical current is passed directly through the metal to be melted. The latter is used in a granulated state. The contact resistances generated in this way enable the concentration of the development of the current heat within the metal to be melted., EE 1 are the plate-shaped electrodes arranged on the narrow walls of the furnace, which with the + -
und Stromleitern verbunden und in denand conductors connected and in the
Ofenwänden luftdicht und isolirt gelagert sind. R ist das Abflufsrohr für das geschmolzene Metall, welches luftdicht mit den zu evacuirenden Gufsformen G verbunden wird. Letztere laufen auf Rädern und werden durch das vom Abflufsrohr R sich abzweigende Saugerohr r der Luftpumpe L evacuirt. Die Verbindung des Ofeninnern mit dem Saugerohr der Luftpumpe erfolgt durch den Stutzen t. Die Luftpumpe L saugt also Luft und sich entwickelnde Gase aus den Gufsformen und dem Ofen mittelst Rohres r und seiner Verbindungen und führt sie durch Rohr R1 nach aufsen ab. Um den Procefs des Schmelzens sichtbar verfolgen zu können, sind Schaugläser g g1 an geeigneter Stelle des Ofens vorgesehen. Ein mit doppeltem luftdichten Schieberverschlufs versehener Schacht oder Fülltrichter T dient zum Beschicken des Ofens, dessen luftdicht schliefsender Deckel erforderlichenfalls entfernt werden kann. . .Oven walls are stored airtight and insulated. R is the drain pipe for the molten metal, which is connected airtight to the Gufsformen G to be evacuated. The latter run on wheels and are evacuated through the suction pipe r of the air pump L, which branches off from the discharge pipe R. The connection between the inside of the furnace and the suction pipe of the air pump is made through the connector t. The air pump L thus sucks air and developing gases from the molds and the furnace by means of pipe r and its connections and carries them outwards through pipe R 1. In order to follow the Procefs melting visible sight glasses are gg 1 at a suitable position of the furnace is provided. A shaft or hopper T provided with a double airtight slide lock is used to load the furnace, the airtight lid of which can be removed if necessary. . .
Um erkennen zu können, dafs die Gufsform gefüllt ist, befindet sich am höchsten PunktIn order to be able to see that the casting mold is filled, it is at the highest point
