Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung bezieht sich auf die Herstellung von Glühkörpern mit gefalteter Oberfläche, eventuell mit eingezogenen Platindrähten, wie solche bereits bekannt geworden sind.The present invention relates to the manufacture of incandescent bodies with folded Surface, possibly with drawn-in platinum wires, as already known are.

Die Erfindung beruht darin, dafs die inneren Faltenkanten zwecks Versteifung und Vergröfserung der leuchtenden Oberfläche durch Nähte zu feststehenden Verticalrippen mit einander verbunden sind, wodurch gleichzeitig ein festes Gerüst gebildet wird, welches die runde Querschnittsform des fertigen Glühkörpers sichert und die Leuchtkraft bedeutend erhöht.The invention is based on the fact that the inner fold edges for the purpose of stiffening and enlarging the luminous surface through seams to form fixed vertical ribs with each other are connected, whereby a solid framework is formed at the same time, which the Round cross-sectional shape of the finished incandescent body ensures and the luminosity significantly elevated.

Auf beiliegender Zeichnung stellt:On the accompanying drawing:

Fig. ι einen Querschnitt des röhrenförmigen und maschenartigen, mit Längsfalten versehenen Gewebes dar, welches nach vorliegender Erfindung zur Herstellung der Glühkörper benutzt wird.Fig. Ι a cross section of the tubular and mesh-like, provided with longitudinal folds Fabric, which is used according to the present invention for the production of the incandescent body will.

Fig. 2 veranschaulicht einen entsprechenden Schnitt nach erfolgter Verbindung der inneren Faltenkanten durch Nähte undFig. 2 illustrates a corresponding section after the connection of the inner Folded edges through seams and

Fig. 3 zeigt eine Seitenansicht eines auf eine Stütze aufgesetzten, fertigen Glühkörpers.3 shows a side view of a finished incandescent body placed on a support.

Zur Herstellung der Glühkörper nimmt man ein Stück des maschenartigen, mit parallelen Längsfalten versehenen Gewebes α von unbestimmter Länge und verbindet alsdann die inneren Faltenkanten auf der Nähmaschine durch Nähte b (Fig. 2), indem man dasselbe flach und in den der gewünschten Anordnung der Falten entsprechenden Zwischenräumen unter die Nadel einer mit einem selbsttätigen Transporteur versehenen Nähmaschine bringt. Nach Fertigstellung der Naht einer jeden Falte wird vortheilhaft zuerst die Naht der gegenüberliegenden Falte hergestellt.To produce the incandescent body, take a piece of the mesh-like fabric α with parallel longitudinal folds of indefinite length and then connect the inner fold edges on the sewing machine with seams b (Fig. 2) by laying it flat and in the desired arrangement of the folds brings corresponding gaps under the needle of a sewing machine provided with an automatic feed dog. After the seam of each fold has been completed, the seam of the opposite fold is advantageously made first.

Hierauf schneidet man das Gewebe in passende Strumpflängen, imprägnirt diese in bekannter Weise mit Lösungen von seltenen Erden, z. B. Thorium und Cer, zieht das obere Ende zusammen und erhält alsdann nach dem Abbrennen einen fertigen Glühkörper, wie er in Fig. 3 dargestellt ist.The fabric is then cut into suitable stocking lengths, these are impregnated in known lengths Way with solutions of rare earths, e.g. B. thorium and cerium, pulls the top together and then receives a finished incandescent body, as shown in FIG. 3, after it has burned off.
