Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei den bisherigen Absprengvorrichtungen für Glas zeigte sich der Uebelstand, dafs die das Glas erhitzende Stichflamme nicht in einer Linie, sondern auf einer breiten Fläche ihre Heizkraft geltend machte, da dieselbe sich an der Glaswand seitlich ausdehnte und dadurch unregelmäfsige Absprengungen erzielt wurden. Liefs man die Flamme indirect durch einen zugeschärften Körper wirken, so würde dieser, aus welchem Material man ihn auch immer fertigte, bald zerstört.The inconvenience of the previous explosive devices for glass showed that the The jet of flame heating the glass is not in a line, but over a wide area Heating power asserted, as the same expanded laterally on the glass wall and thereby irregular blasts were achieved. If you let the flame go through you indirectly sharpened body, it would be made of whatever material it was made of finished, soon destroyed.
Auf der Zeichnung ist ein neues Verfahren zum Formen der Stichflamme schematisch dargestellt. A new method for shaping the jet flame is shown schematically in the drawing.
Der in Umdrehung versetzte Glaskörper a wird durch eine aus dem Brenner b tretende Stichflamme' erhitzt, die durch den mit einem Schlitz versehenen Brennerkopf eine flache Form erhält.The glass body a , which is set in rotation, is heated by a jet flame emerging from the burner b , which is given a flat shape by the burner head provided with a slot.
Um zu verhüten, dafs die den Glaskörper a berührende Stichflamme sich an demselben seitlich ausdehnt, wird von beiden Seiten her gegen die Spitze der Stichflamme aus den abgeflachten Kanälen c c ein starker, kalter Luftstrom gelenkt. Diese Luftströme drücken die Stichflammenspitze zu einer schmalen Linie zusammen und halten die neben der Stichflamme befindlichen Glasflächen kühl, so dafs die Trennung des Glases an der schmalen, erhitzten Linie erfolgt.In order to prevent the jet flame touching the glass body a from expanding laterally on the same, a strong, cold stream of air is directed from both sides towards the tip of the jet flame from the flattened channels cc. These air currents compress the tip of the jet of flame into a narrow line and keep the glass surfaces next to the jet of flame cool, so that the glass is separated at the narrow, heated line.
