KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Bei den bestehenden Glühlampenhaltern, in welche die Lampen mit ihrer Fassung eingeschraubt werden, bestehen die Uebelstä'nde, dafs die Lampen sich durch Erschütterungen in den Haltern lösen, und dafs durch ein zu festes Einschrauben leicht Beschädigungen an den Lampen hervorgerufen werden.With the existing light bulb holders into which the lamps are screwed with their socket there are evils that the lamps are shaken by vibrations loosen in the holders, and that can easily be damaged by screwing in too tightly caused by the lamps. Diesen Uebelständen soll nun dadurch begegnet werden, dafs man die das Muttergewinde des Halters bildende Hülse federnd einrichtet, so dafs sie stets einen mäfsig starken Druck von allen Seiten auf das Gewinde der Lampenfassung ausübt, während sie bei zu festem Einschrauben der Lampe nachgiebt und ein Ueberschrauben zuläfst.These evils should now be countered by removing the female thread of the holder forming the resilient sleeve, so that it is always moderately strong Apply pressure from all sides on the thread of the lamp socket while closing it gives way to screwing in the lamp tightly and allows screwing. Einen derartigen Lampenhalter zeigt die beiliegende Zeichnung. Die Hülse α desselben ist, wie gewöhnlich, aus Metallblech hergestellt, in das die erforderlichen Gewindegänge eingeprefst sind. Es ist dazu aber ein möglichst federhartes Metall verwendet, und sind in die Hülse mehrere Längseinschnitte c gemacht, dürek, welche die federnden Lappen b gebildet werden. Zur Erhöhung des elastischen Druckes, den diese Lappen gegen das Gewinde der Lampenfassung d ausüben, ist der Rand der Hülse mit einer Hohlkehle versehen und in diese eine zu einem Ring gestaltete Spiralfeder e eingelegt. Um ihren Zweck vollständig zu erfüllen,- sind die Theile so zu bemessen, dafs die Lappen b gleich bei Anfang des Einschraubens der Lampe einen Druck gegen die Fassung d ausüben, und dafs dieselben bei stattfindendem Ueberschrauben der Lampe nicht über ihre Elasticitätsgrenze hinaus in Anspruch genommen werden.The accompanying drawing shows such a lamp holder. The sleeve α of the same is, as usual, made of sheet metal into which the required threads are pressed. For this purpose, however, a metal that is as hard as possible is used, and several longitudinal incisions c are made in the sleeve, which form the resilient tabs b . To increase the elastic pressure that these tabs exert against the thread of the lamp holder d , the edge of the sleeve is provided with a groove and a spiral spring e designed to form a ring is inserted into it. In order to fully fulfill their purpose, the parts are to be dimensioned in such a way that the tabs b exert a pressure against the socket d as soon as the lamp is screwed in, and that the latter are not stressed beyond their elastic limit when the lamp is screwed on will. Patenτ-Ansρrüch:Patenτ request: Bei Glühlampenhaltern, die mit einer zum Einschrauben der Lampe dienenden ' Mütterhülse versehen sind, die gleichzeitige Anordnung von Einschnitten c an der Hülse α und einer um letztere gelegten Spiralfeder e, zum Zwecke, ein Lockerwerden der Lampe durch' Erschütterungen, sowie ein übermäfsiges festes Einschrauben und die hieraus entstehende Beschädigung derselben zu verhindern.In the case of incandescent lamp holders, which are provided with a nut sleeve that is used to screw in the lamp, the simultaneous arrangement of incisions c on the sleeve α and a spiral spring e wrapped around the latter, for the purpose of loosening the lamp due to vibrations, as well as excessive screwing in and to prevent the resulting damage to the same.
