ffletallsockel für elektrische Glühlampen (Lampenfüße).Metal base for electric light bulbs (lamp bases).

Patentiert im Deutschen Reiche vom 13. Oktober 1911 ab.Patented in the German Empire on October 13, 1911.

Die bisher auf den Markt gebrachten Metallsockel für Glühlampen mit von der Kontakthülse isoliertem Rand zur Aufnahme des Glaskörpers der Lampe haben für deren praktische Verwendung zum Nachteil, daß ihr Eigengewicht durch die Isolation unverhältnismäßig groß ist. Außer den dadurch vermehrten Frachtspesen macht sich dieser Umstand in der durch das hohe Gewicht bedingten stärkeren Erschütterung, speziell bei Metallfadenlampen durch vermehrten Bruch, unangenehm bemerkbar. Das bisherige Isolieren des Randes durch Zwischenschalten eines Glaskörpers, welcher in warmem Zustande eingequetscht werden muß, bedingt in der Herstellung solcher Sockel einen großen Ausfall an fehlerhaften Stücken.The metal base for incandescent lamps with a contact sleeve that has been brought onto the market so far insulated edge to accommodate the glass body of the lamp have for their practical Use to the disadvantage that their own weight is disproportionate due to the insulation is great. In addition to the increased freight charges, this fact makes itself in the strong vibrations caused by the heavy weight, especially with metal filament lamps due to increased breakage, uncomfortable noticeable. The previous isolation of the edge by inserting a glass body, which must be squeezed in when warm, due to the manufacture of such Socket a large failure of faulty pieces.

Den Gegenstand der Erfindung bildet nun ein Metallsockel für elektrische Glühlampen, bei welchem die genannten Nachteile vermieden sind, indem die Kontakt- und Randhülse nicht wie bisher durch Isoliermaterial, sondern unter Zwischenlage von in kaltem Zustande preßbarem Isoliermaterial direkt miteinander verbunden sind.The subject of the invention now forms a metal base for electric incandescent lamps, in which the disadvantages mentioned are avoided by the contact and edge sleeve not as before by means of insulating material, but with the interposition of in a cold state compressible insulating material are directly connected to one another.

Auf der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes je im Vertikalschnitt dargestellt.In the drawing, two embodiments of the subject invention are each in Vertical section shown.

Nach Fig. 1 ist die mit rundem Gewinde versehene, am oberen Teil in bekannter Weise ausgebildete Kontakthülse a an ihrem unteren, offenen Ende mit zwei dicht übereinander angeordneten Flanschen b, c versehen. Zwischen denselben befindet sich ein doppelter, aus elektrisch isolierendem Material, z. B. Hartpapier, Gummi usw., bestehender Ring d, in dem der obere, nach innen ragende Rand einer zur Aufnahme der Glasbirne dienenden Randhülse e eingeklemmt ist, derart, daß die letztere unter Zwischenlage des Isolierringes d fest mit der Kontakthülse verbunden ist.According to FIG. 1, the contact sleeve a, which is provided with a round thread and formed in a known manner on the upper part , is provided at its lower, open end with two flanges b, c arranged close to one another. Between the same is a double, made of electrically insulating material, for. B. hard paper, rubber, etc., existing ring d, in which the upper, inwardly protruding edge of a serving to accommodate the glass bulb edge sleeve e is clamped, such that the latter is firmly connected to the contact sleeve with the interposition of the insulating ring d.

Statt aus einem doppelten Ring kann die Isolation aus zwei und mehr Ringen bestehen, z. B. aus zwei Kartonringen und einem an der Kontakthülse anliegenden, einen oder beide Kartonringe übergreifenden Gummiring.Instead of a double ring, the insulation can consist of two or more rings, z. B. from two cardboard rings and one adjacent to the contact sleeve, one or both Cardboard rings overlapping rubber ring.

Bei der in Fig. 2 dargestellten Ausführungsform des Erfindungsgegenstandes ist das untere, offene Ende der ebenfalls mit rundem Gewinde versehenen Kontakthülse a' in den oberen, nach oben ragenden Rand einer Randhülse e' geschoben und durch einen Wulst f fest mit derselben verbunden, wobei zwischen Kontakt- und Randhülse ein Ring d' eingeklemmt ist. Derselbe besteht, wie in Fig. 1 der Ring d, zwecks elektrischer Isolierung von Kontakt- und Randhülse aus elektrisch isolierendem, in kaltem Zustand preßbarem bzw. biegbarem Material, z. B. Karton, Gummi, Asbest usw.In the embodiment of the subject matter of the invention shown in Fig. 2, the lower, open end of the contact sleeve a ', which is also provided with a round thread, is pushed into the upper, upwardly protruding edge of an edge sleeve e' and is firmly connected to the same by a bead f, with between Contact and edge sleeve a ring d 'is clamped. The same consists, as in Fig. 1, the ring d, for the purpose of electrical insulation of the contact and edge sleeve of electrically insulating, in the cold state compressible or bendable material, for. B. cardboard, rubber, asbestos, etc.
