Die die Pfannen 14 tragenden Wollen 27 sind miteinander durch Zahnräder 28-ver. bunden, so dass, wenn der die Pfannen tragende Wagen die in Fig. 1 gezeigte Giessstellung auf dem Tisch 12 einnimmtund mittels, Handkurbel 29 gedreht wird, beide Gruppen von Pfannen 14 in eine geneigte Lage übergeführt werden (Fig. 3).
Da die Tüllen 15 der Pfannen 14 von gleicher Grösse sind, so wifd-dementsprechend auch eine gleich grosse Metallmenge aus jeder Pfanne abfliessen, welche Mengen infolge der gleichen Höhenlage der Pfannen mit gleicher Geschwindigkeit und gleichem Druck in die Eingüsse 19 der Formen 17 eingeführt werden, von welchen dieselben in die Einläufe 22 gelangen, die das Metall gleichmässig nach jeder Seite der Eingüsst1 in den Hohlraum 23 der Form 17'verteilen. Die Metallmengen werden dementsprechend unter der gleichzeitig denselben mitgeteilten Geschwindigkeit und Druck gleichmässig schnell in den Hohlraum 23 fliessen und sich darin gleich schnell ausbreiten und vereinigen.
Der schnelle und gleichmässige Fluss des Metalles verhindert eine schädliche Temperaturerniedrigung desselben, so dass dasselbe während des Giessens des Rohres in einen zur Erzielung eines reinen bezw. fehlerlosen Gusses erforderlichen Zustand erhalten wird. Infolge der glatten Oberfläche der Wände des Hohlraumes 28 wird gleichzeitig dem so erhaltenen fehlerfreien Rohr eine glatte Oberfläche mitgeteilt. Dieses ist nach Entfernung des Oberkastens der Form und nach Herausnahme aus dem Unterkasten zum sofortigen Gebrauch bezw. zur Bearbeitung geeignet. Die während des Giessens entstehenden Gase werden in bekannter Weise von dem Kern 25 sowie der Nut 23 der Form 17 aufgenommen.
Nach Entfernung des Wagens 13 von dem Drehtisch 12 und nach Drehung des letzteren um die Entfernung zweier Formen von einander, wird ein zweiter Wagen, dessen Pfannen inzwischen mit flüssigem Metall gefüllt sind auf den Tisch geschoben.

The wool 27 carrying the pans 14 are connected to one another by gears 28-ver. bound so that when the carriage carrying the pans assumes the casting position shown in Fig. 1 on the table 12 and is rotated by means of a hand crank 29, both groups of pans 14 are transferred into an inclined position (Fig. 3).
Since the spouts 15 of the pans 14 are of the same size, an equal amount of metal will accordingly flow out of each pan, which amounts are introduced into the sprues 19 of the molds 17 at the same speed and with the same pressure due to the same height of the pans from which the same pass into the inlets 22, which distribute the metal evenly to each side of the sprues 1 into the cavity 23 of the mold 17 ′. The amounts of metal will accordingly flow evenly and quickly into the cavity 23 at the same speed and pressure communicated at the same time and will spread and unite therein at the same speed.
The fast and even flow of the metal prevents the same from a harmful lowering of temperature, so that the same during the pouring of the pipe in a to achieve a clean respectively. flawless casting is obtained. As a result of the smooth surface of the walls of the cavity 28, a smooth surface is provided at the same time to the flawless pipe thus obtained. This is BEZW after removal of the upper case of the form and after removal from the lower case for immediate use. suitable for processing. The gases produced during casting are absorbed in a known manner by the core 25 and the groove 23 of the mold 17.
After the carriage 13 has been removed from the turntable 12 and the latter has been rotated by the distance between two molds, a second carriage, the pans of which have meanwhile been filled with liquid metal, is pushed onto the table.
