KLASSE 32: Glas.CLASS 32: Glass.
Patentirt im Deutschen Reiche vom 26. Juli 188a ab.Patented in the German Empire on July 26, 188a.
Bei den nach Patent No. 5675 hergestellten gläsernen Spritzen werden die Gamiturtheile auf Glasgewinde geschraubt, welche in der daselbst beschriebenen Art direct in die Glascylinder geschnitten werden. Diese Herstellung von Glasgewinden ist jedoch ziemlich umständlich und hat den Nachtheil, dafs die eingeschnittenen Gewinderillen sehr schnell die Gewinde der Garniturstücke zerkratzen. Diese beiden Uebelstände fallen bei den in nachbeschriebener Weise hergestellten Cylindern mit Glasgewinde fort. Das Verfahren bietet aufserdem noch den Vortheil, dafs der Innenraum des Cylinders gleichfalls cylindrisch und bei allen in einer Form gefertigten Stücken durchaus gleich ist, während die bisher zu den Cylindern verwendeten Röhren .alle verschieden und oft so uncylindrisch sind, dafs ein Ausschleifen erforderlich wird.The patent no. The glass syringes made in 5675 will open the gamiturt parts Screwed glass thread, which is screwed directly into the glass cylinder in the manner described there get cut. However, this production of glass threads is quite cumbersome and has the disadvantage that the incised thread grooves very quickly become the thread of the Scratch pieces of clothing. These two inconveniences fall in the case of the one described below Way manufactured cylinders with glass thread continue. The method also offers the The advantage that the interior of the cylinder is likewise cylindrical and in all of them in one Shape made pieces is quite the same, while the previously used to the cylinders Tubes are all different and are often so uncylindrical that grinding out is necessary will.
Fig. ι zeigt einen Grundrifs A-B, Fig. 2 den Schnitt C-D-E einer Form, wie solche im wesentlichen zur Herstellung der neuen Cylinder erforderlich ist.Fig. Ι shows a Grundrifs AB, Fig. 2 the section CDE of a shape such as is essentially required for the production of the new cylinder.
Wird in diese Form bei D heifsflüssiges Glas hineingethan und der Kolben F, welcher bei ahm. einer entsprechenden Führung sitzt, nach c heruntergedrückt, so erhält man die gezeichnete Form d. If hot liquid glass is put into this form at D , and the flask F, which at ahm. a corresponding guide sits, pushed down towards c, you get the drawn shape d.
Eine besondere Eigenartigkeit zeigt der Metallstempel F noch darin, dafs derselbe eine Ausbohrung ef enthält, welche beim Niederdrücken des Kolbens durch den Stift g h geschlossen ist, während vor dem Aufziehen des Kolbens der Stift g h gehoben wird und dadurch ein Luftkanal entsteht. Da der Kolbengang bei Spritzen es erfordert, dafs der Innenraum durchaus cylindrisch ist, können die in Rede stehenden Röhren nur mit Hülfe des eben erwähnten Luftkanales hergestellt werden. Wäre kein Luftkanal in dem Kolben F, so würde die Luftansaugung das noch weiche, geformte Glas beim Hochgehen des Kolbens F vollständig ausformen. Ist der Kolben nach ausgeübter Pressung wieder hochgegangen, so werden die Theile i k der Metallform, welche sich um / und m drehen, aus einander geklappt, und der Spritzencylinder d ist, nachdem derselbe abgekühlt ist und der überflüssige Theil η 0 p q bei η ο abgesprengt ist, zum Gebrauche bezw. zur Zusammenstellung mit den Garniturtheilen fertig. Damit der Theil η ο p q sich leichter absprengen läfst und die Stirnfläche des Rohres daselbst sogleich einen glatten Ansatz erhält, ist bei η ο ein Ring in die Eisenform eingelassen bezw. in der Metallform stehen gelassen. The metal punch F shows a particular peculiarity in the fact that it contains a bore ef which is closed by the pin gh when the piston is pressed down, while the pin gh is raised before the piston is drawn open, thereby creating an air channel. Since the barrel of the plunger in syringes requires that the interior be absolutely cylindrical, the tubes in question can only be made with the aid of the air channel just mentioned. If there were no air duct in the piston F, the air intake would completely form the still soft, shaped glass when the piston F goes up. When the plunger has risen again after the pressure has been exerted, the parts ik of the metal mold, which rotate around / and m , are folded apart, and the syringe cylinder d is, after it has cooled down and the superfluous part η 0 pq at η ο, blasted off is, for use respectively. ready to put together with the set parts. So that the part η ο pq can be more easily split off and the end face of the pipe there immediately receives a smooth approach, a ring is let into the iron form at η ο or. left in the metal mold.
