Die Arbeitsweise nac1f der Erfindung ist ungefähr die folgende : Wenn der bei 14 angedeutete Zylinder vermittelst des Pfeifenkopfes 8 und der Pfeife 9 von der Glasoberfläche innerhalb des Steines 10 nach oben gezogen wird, so ist seine Lage ungefähr die in Fig. 2 gezeigte, wo die rechte Zylinderwand 15 oberhalb der schrägen Wandfläche 13 liegt, die sich bis unter das Glas hin erstreckt. Wäre der Vorsprung 13 nicht vorhanden, so wäre der Glasspiegel an dieser Seite heisser und diinl1flüssiger. Es würde dann die Glasstärke des Zylinders an dieser Seite schwächer werden ; auch würde die Walzenwurzel während des Ziehens nach links wandern, was natürlich nicht erwünscht ist.
Beides wird durch den Vorsprung 13 vermieden, da er das Glas darüber gegen die Strahlung des Glases darunter abschirmt, auch den Aufstieg des heissen Glases nach links verschiebt. Die viereckige Ausbildung des Steines 10 trägt dazu bei, die schräge Fläche 13 an der dem Herde zugekehrten Seite und die senkrechte Fläche auf der entgegengesetzten Seite in ihrer Stellung festzuhalten. Der Stein 10 kann aus irgend einem passenden Material hergestellt werden ; vorzugsweise wird jedoch dazu der feuerfeste Ton benutzt, der im allgemeinen bei solchen Anordnungen zur Verwendung gelangt.
PATENT-ANSPRÜCHE :
1, Mit der Wanne zusammenhängender Ziehherd für die Herstellung von Glaszylindern, mit einem in seiner mittelöffnung die Ziebstelle aufnehmenden Steine, dadurch gekennzeichnet, dass die innere Wand des die Ziehstelle aufnehmenden Steines (10) an der der Wanne (3) zugekehrten Seite nach unten und innen vorgezogen ist (bei 13).

The method of operation according to the invention is approximately as follows: When the cylinder indicated at 14 is pulled upwards from the glass surface within the stone 10 by means of the pipe bowl 8 and the pipe 9, its position is approximately that shown in FIG right cylinder wall 15 is above the inclined wall surface 13, which extends to under the glass. If the projection 13 were not present, the glass mirror on this side would be hotter and more fluid. The glass thickness of the cylinder on this side would then become weaker; the roller root would also move to the left during the pulling process, which of course is not desired.
Both of these are avoided by the projection 13, since it shields the glass above it from the radiation from the glass below, and also shifts the rise of the hot glass to the left. The square shape of the stone 10 helps to hold the inclined surface 13 on the side facing the herd and the vertical surface on the opposite side in place. The stone 10 can be made of any suitable material; however, the refractory clay generally used in such arrangements is preferably used for this purpose.
PATENT CLAIMS:
1, Draw hearth connected to the tub for the production of glass cylinders, with a stone receiving the drawing point in its central opening, characterized in that the inner wall of the stone (10) receiving the drawing point on the side facing the tub (3) downwards and inside is preferred (at 13).
