Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

in WIEN.in Vienna.

Gegenstand vorliegender Erfindung bezieht sich auf eine Lampenfassung für Telephonlämpchen, die das Einfügen der eigentlichen Lampe in einfacher Weise ermöglicht und dabei die Lampe in ihrer relativen Lage festlegt. The present invention relates to a lamp holder for telephone lamps, which allows the actual lamp to be inserted in a simple manner and thereby fixes the lamp in its relative position.

Es gewährt dies den Vorteil, daß bei Neuanschaffungen die alte Fassung immer wieder verwendet werden kann, und daß alle Übelstände, die an der bisher üblichen Befestigung der Kontakte haften, vermieden werden.This gives the advantage that when new purchases are made, the old version is always used again can be used, and that all the inconveniences associated with the previously customary attachment of the contacts stick, should be avoided.

In beiliegender Zeichnung zeigen die Fig. ι und 2 je eine Ausführungsform der vorliegenden Erfindung, während Fig. 3 einen Schnitt nach der Linie A-A in Fig. 1 darstellt. In the accompanying drawing, FIGS. 1 and 2 each show an embodiment of the present invention, while FIG. 3 shows a section along the line AA in FIG.

Die Einrichtung besteht in zwei einander gegenüberstehenden, parallel angeordneten Metallplättchen, die Abschnitte eines Kreiszylinders bilden und gegeneinander isoliert an dem Holzdorn α befestigt sind. Die freistehenden Lappen b umfassen federnd das eigentliche Lämpchen und vermitteln den Kontakt mit dem Glühlampenfaden. Um die aus der Lampe herausragenden freien Drahtenden mit den Lappen b in sicheren Kontakt zu bringen, enthält der Dorn α an einer beliebigen Stelle an der Peripherie eine Ausnehmung, in die die Abstechspitze der Lampe hineinpaßt, wodurch die letztere in ihrer Lage genau festgelegt ist (Fig. 1). Bei der Ausführungsform nach Fig. 2 ist der Dorn α noch mit einem zentralen Stäbchen c versehen, das in eine entsprechende Vertiefung der Lampe hineinpaßt. The device consists of two opposing, parallel arranged metal plates, which form sections of a circular cylinder and are attached to the wooden mandrel α isolated from one another. The free-standing tabs b resiliently encompass the actual lamp and provide contact with the filament of the incandescent lamp. In order to bring the free wire ends protruding from the lamp into secure contact with the tabs b , the mandrel α contains a recess at any point on the periphery into which the cutting tip of the lamp fits, whereby the position of the latter is precisely defined ( Fig. 1). In the embodiment according to FIG. 2, the mandrel α is also provided with a central rod c which fits into a corresponding recess in the lamp.
