KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist bekannt, Gegenstände aus schwer schmelzbarem Material in der Weise herzustellen, daß man in einer Kohlenform mittels eines elektrischen Ofens das Material bis zum Schmelzpunkt erhitzt (vergl. z. B. die deutsche Patentschrift 113817, Kl. 80).It is known to manufacture objects made of difficult-to-melt material in such a way that that one in a charcoal form by means of an electric furnace the material up to Melting point heated (see, for example, German patent specification 113817, class 80).
Gegenüber dieser bekannten Art unterscheidet sich das vorliegende Verfahren dadurch, daß die Form am Boden eine Öffnung hat, durch welche das geschmolzene Material in Form eines Stabes oder einer Röhre ausfließt. Compared to this known type, the present method differs in that that the mold has an opening at the bottom through which the molten material flows out in the form of a rod or a tube.
Ein Vorteil des Verfahrens ist es, daß der Ofen nicht jedesmal nach Fertigstellung eines Formstückes ausgeschaltet zu werden braucht, was Zeit- und Wärmeverlust zur Folge hat, sondern daß der Ofen ununterbrochen in Betrieb sein kann. Außerdem lassen sich ohne besondere Formen beliebig lange Röhren usw.One advantage of the method is that the furnace does not need to be re-opened every time a The fitting needs to be switched off, which results in loss of time and heat, but that the furnace can operate continuously. In addition, you can do without special shapes tubes of any length, etc.

In Fig. ι (A Ansicht von oben, B Schnitt von der Seite) der beiliegenden Zeichnung ist ein für das Verfahren benutzter Kohlenspiralenofen dargestellt. In diesem Ofen ist eine Kohlenform f oder eine andere Form z. B. aus Platin-Iridium angebracht, welche gemäß vorliegender Erfindung am Boden eine Öffnung hat. Diese Form wird mit Quarzstückchen, Quarzstaub oder reinem Sand gefüllt. Sodann wird der elektrische Strom durch den Ofen geleitet, wodurch sich die Kohlenspirale h mit der Form f schnell erhitzt. Ist genügende Hitze erreicht, so kommt das in der Form befindliche Material zum Schmelzen und verläßt dann durch die geeignet gestaltete Bodenöffnung in Form eines Stabes oder Rohres nach unten den Ofen. In dem Maße, in welchem nun die geschmolzene Masse abfließt, wird nun die Form mit neuem Material nachgefüllt, so daß also Stäbe und Röhren beliebiger Länge erhalten werden.In Fig. Ι (A view from above, B section from the side) of the accompanying drawing, a coal spiral furnace used for the method is shown. In this furnace a charcoal shape f or some other shape z. B. made of platinum-iridium, which according to the present invention has an opening at the bottom. This form is filled with pieces of quartz, quartz dust or pure sand. The electric current is then passed through the furnace, as a result of which the carbon spiral h with the shape f heats up quickly. Once sufficient heat has been reached, the material in the mold melts and then leaves the furnace through the appropriately designed bottom opening in the form of a rod or tube. As the molten mass flows off, the mold is then refilled with new material, so that rods and tubes of any length are obtained.
Fig. 3 stellt einen Schnitt der Heizspirale mit Form/ in größerem Maßstabe dar. Hier tritt ein innerhalb der Form f angebrachter Kohlenstab, welcher, mit Oxydgemisch überzogen , ebenfalls Verwendung finden kann, z. B. zu Bogenlichtstäben, besser hervor. Dieser Kohlenstab kann selbstverständlich auch fehlen. Die Rohre werden in bekannter Weise wie bei der Glasfabrikation herausgezogen.Fig. 3 shows a section of the heating coil with shape / on a larger scale. Here, a carbon rod mounted inside the shape f occurs, which, coated with oxide mixture, can also be used, for. B. to arc light sticks, better. This carbon stick can of course also be missing. The tubes are pulled out in a known manner, as in glass manufacture.
Fig. 2 stellt einen ähnlichen Schnitt dar. Hierbei steht jedoch der als Kern dienende Kohlen- oder Iridium- usw. Stab mit der Form/ in fester Verbindung, kann also nicht nach unten herausgleiten.Fig. 2 shows a similar section. Here, however, is the one serving as the core Carbon or iridium, etc. rod with the form / in a fixed connection, so it cannot slide out downwards.
