  Glühlampe mit   Metallglohfdden.   



   Man   hat vorgeschlagen, Metallglühfäden   vor dem Einschmelzen in die Glocken an Traggestellen mit   mehreren   Tragstützen zu befestigen. Da diese Traggestelle durch den engen Hals der Glocke geschoben werden müssen, so nehmen sie einen ungefähr zylindrischen Raum ein. Bisher wurden die einzelnen   Tragstützen   nur an den Endflächen dieses zylindrischen Raumes angebracht und der Faden zwischen denselben zickzackförmig. von der achsialen Richtung nicht stark abweichend geführt. Diese Anordnung bringt gewisse   überstände mit   sich. Erstens sendet die   Lampe achsial wenig Licht aus.

   Zweitens   ist bei längeren Traggostellen der   Durchhang der Faden, wenn   sie zum Glühen gebracht werden, so   gross,   dass   Berührung   der einzelnen Fadenteile eintreten kann. 



   Diesen Übelständen wird nach vorliegender Erfindung durch entsprechende Anordnung 
 EMI1.1 
 eine derartige Lampe,   bei welcher die mittleren Tragstützen ungefähr   in halber Hohe des Traggestelles sternförmig angeordnet sind. Bei dieser Lampe sind   ferm'r alk'spitzen Ab-   biegungen des Fadens vermieden. welche Kurzschlüsse einzelner Fadenteile herbeiführen konnten. 



   Werden die Tragstützen in   mehreren     Höhen angebracht,   so kann der Faden statt 
 EMI1.2 
 wird bedeutend   grösser   und die Lichtverteilung sehr günstig. Zur Fadenbefestigung sind Häkchen vorgesehen, wie solche beispielsweise bei Osmiumlampen vorkommen. 



   Dieselbe   Fadenform   wie bei Fig. 3 kann nach Fig. 4 dadurch erreicht werden, dass am Traggestelle längere Tragstützen angebracht sind, welche über den durch den Hals bestimmten zylindrischen Raum hinausgreifen, aber biegsam sind. Bei der   Einführung   des

   PATENT-ANSPRÜCHE : 
1. Glühlampe mit Metallglühfäden, welcher von einem einen ungefähr zylindrischen Raum einnehmenden Traggestell getragen wird, an dessen Enden Tragstützen sitzen, dadurch gekennzeichnet, dass weitere Tragstützen angeordnet sind,   um   den freien   Durchhang   der Fadenteile zu verringern.

  Incandescent lamp with metal threads.



   It has been proposed that metal filaments be attached to support frames with a plurality of support posts prior to melting into the bells. Since these support frames have to be pushed through the narrow neck of the bell, they take up an approximately cylindrical space. So far, the individual support supports were only attached to the end faces of this cylindrical space and the thread between the same zigzag. out of the axial direction not very different. This arrangement entails certain protrusions. First, the lamp emits little light axially.

   Secondly, in the case of longer Traggostellen the slack of the thread, when they are brought to glow, is so great that the individual thread parts can come into contact.



   According to the present invention, these deficiencies are alleviated by an appropriate arrangement
 EMI1.1
 such a lamp, in which the middle support supports are arranged in a star shape approximately halfway up the support frame. With this lamp, sharp bends in the thread are avoided. which short circuits of individual parts of the thread could cause.



   If the supports are attached at several heights, the thread can take place
 EMI1.2
 becomes significantly larger and the light distribution is very favorable. Hooks, such as those found in osmium lamps, are provided for fastening the thread.



   The same thread shape as in FIG. 3 can be achieved according to FIG. 4 in that longer support supports are attached to the support frames, which extend beyond the cylindrical space defined by the neck, but are flexible. When the
 EMI1.3
 aligned.



   PATENT CLAIMS:
1. Incandescent lamp with metal filaments, which is carried by a support frame occupying an approximately cylindrical space and at the ends of which support supports are seated, characterized in that further support supports are arranged in order to reduce the free sag of the filament parts.

2. Glühlampe nach Anspruch 1, dadurch gekonnzeichnet, dass die Tragstütxen derart angeordnet sind, dass der Faden schraubenförmig auf dem Traggestelle aufgewunden werden kann, um die Lichtverteilung zu verbessern. <Desc/Clms Page number 2> 2. Incandescent lamp according to claim 1, characterized in that the Tragstütxen are arranged such that the thread can be wound helically on the support frame in order to improve the light distribution. <Desc / Clms Page number 2> 3. Glühlampe nach Anspruch l, dadurch gekennzeichnet, dass ein Teil der Tragstutzen an der Glocke angebracht ist, so dass der Faden ausserhalb des vom Traggestell eingenommenen Raumes untergebracht werden kann.
