 geöffnet werden. Der dünne Teil des Glasstromes wird beim Schluss der Messer aufgesammelt und ein neuer Posten staut sich an. Da sich während der Bildung des Pfostens   also während der   ammlung einer bestimmten Menge Glases dieses sich in einer geheizten Kammer befindet, so hat der ganze Posten gleichfömige Temperatur und Blasen können sich nicht an der Oberfläche oder in der Masse bilden. 



   Wenn auch die Ausflussöffnung während des Gebrauchs gleichförmig gross gehalten werden kann, so ändert sich doch der Zufluss der Glasmasse von einem vollständig freien   Zufluss, wen@

    PATENT ANSPRÜCHE :  
1. Vorrichtung zur Zufühmng von geschmolzenem Glas aus einem Hafen, einer Wanne oder dgl. in eine Form. dadurch gekennzeichnet ; dass das Glas in eine Kammer eintropft, die für gewöhnlich an ihrem   unterenEnde geschlossen   und so gross ist, dass die Wände mit der sich in der Kammer ansammelnden Glasmasse nicht in Berührung kommen. um   fehlerhafte SteUen, Streifen,   Blasen und dgl. an dem angesammelten Glasposten zu vermeiden.

 be opened. The thin part of the glass flow is collected at the end of the knife and a new batch accumulates. Since a certain amount of glass is in a heated chamber while the post is being formed, the whole post is at a constant temperature and bubbles cannot form on the surface or in the mass.



   Even if the outflow opening can be kept uniformly large during use, the inflow of the glass mass changes from a completely free inflow if @

 every handicap takes place. If the closure of the chamber was not provided with the cavity described, the glass flow would spread when it was closed and come into contact with the walls of the chamber. This is precisely why those cooling errors would become apparent.

 so that the risk of air bubbles forming is reduced.



    PATENT CLAIMS:
1. Apparatus for feeding molten glass from a port, a tub or the like. Into a mold. characterized ; that the glass drips into a chamber which is usually closed at its lower end and is so large that the walls do not come into contact with the glass mass that has accumulated in the chamber. in order to avoid faulty controls, stripes, bubbles and the like on the accumulated glass gob.

 

Claims (1)

2. Vorrichtung nach Anspruch l. dadurch gekennzeichnet, dass der untere Abschluss der Kammer (A), in welcher sich das Glas ansammelt. aus zwei gegeneinander anstossenden Abtrennvorrichtungen (16, 17) gebildet ist, die hin und her beweglich sind und in Offenstellung die an- gesammelte Glasmasse in die Vorform oder dgl. eintropfen lassen. 2. Apparatus according to claim l. characterized in that the lower end of the chamber (A) in which the glass accumulates. is formed from two mutually abutting separating devices (16, 17) which can be moved back and forth and in the open position allow the accumulated glass mass to drip into the preform or the like. 3. Vorrichtung nach Anspruch l, dadurch gekennzeichnet, dass der Boden der Kammer (A) derartig muldenförmig ausgebildet ist, dass das Ausbreiten des Glases nahe seinem unteren Ende gegen die Wand der Kammer hm verhindert wird. 3. Apparatus according to claim l, characterized in that the bottom of the chamber (A) is trough-shaped in such a way that the spreading of the glass near its lower end against the wall of the chamber hm is prevented. 4. Vorrichtung nach Anspruch l und 3, dadurch gekennzeichnet, dass die Abtrenn- EMI2.4 Ht, ellen versehen nd, um die die Ausbreitung des Glases verhindernde Mulde am Boden zu bilden. 4. Apparatus according to claim l and 3, characterized in that the separating EMI2.4 Ht, ellen provided in order to form the hollow on the floor that prevents the glass from spreading. 5. Vorrichtung nach Anspruch l und 4, dadurch gekennzeichnet, dass die Abtrennmesser (16, 17) sich so schliessen, dass sie das aus der Kammer (A) austretende Glas an dem Halse abschneiden, welcher durch den Zug des sinkenden Glaspostens sich bildet. 5. Apparatus according to claim l and 4, characterized in that the severing knives (16, 17) close so that they cut off the glass emerging from the chamber (A) at the neck which is formed by the pull of the falling glass gob. 6. Vorrichtung nach Anspruch l und 3, dadurch gekennzeichnet, dass der grösste Durch- EMI2.5 6. Apparatus according to claim l and 3, characterized in that the largest through EMI2.5
