Sicherungseinrichtung gegen unbeabsichtigtes Abschrauben der Fassungen elektrischer Glühlampen vom Rohrnippel.Safety device against unintentional unscrewing of the socket electric light bulbs from the pipe nipple.

Patentiert im Deutschen Reiche vom 29. Mai 1924 ab.Patented in the German Empire on May 29, 1924.

Ein Nachteil der bisher bekannten Glüh-A disadvantage of the previously known annealing

lampenfassungen besteht darin, daß sie keine sichere Gewähi bieten gegen Abschrauben vom Rohrnippel bei Linksdrehen der Fassung, z. B.lamp sockets is that they do not offer a secure protection against unscrewing Pipe nipple when turning the socket to the left, e.g. B.

B. bei offenen Schalenhaltern, unter einen Steg des Schalenhalters zuwhen unscrewing the bulb. In the case of the previously used as protection against this in the neck of the socket attached grub screws it happens that when screwing on the socket the grub screw, z. B. with open shell holders, under a web of the shell holder

In the case of closed shell skins, however, this has so far been possible at all no opportunity to tighten the grub screw.

Dieser Nachteil soll durch vorliegende Erfindung, unter Fortlassung der Madenschraube, dadurch behoben werden, daß die Lampenfassung in ihrem den Rohrnippel um·This disadvantage is intended by the present invention, omitting the grub screw, can be remedied by the fact that the lamp socket in its pipe nipple around

In dem mit glatter, gewindeloser Bohrung versehenen Fassungshals α ist eine Schraubenfeder b angeordnet, deren Drahtstärke der Tiefe des Nippelgewindes entspricht. Die Wickelrichtung der Feder ist hier in bekannter Weise so gewählt, daß sie sich beim Rechtsdrehen der Fassung, also beim Aufschrauben auf den Roh'rnippel, entgegengesetzt ihrer Wickelrichtung zu öffnen sucht. Der untere Federschenkel c ist fest im Fassungshals abgestützt, während der obere Federschenkel d in einem kleinen Schlitz e des Fassungshalses beweglich nach rechts und links etwas Spielraum hat.Fig. 2 is a plan view.
A helical spring b , the wire thickness of which corresponds to the depth of the nipple thread, is arranged in the socket neck α, which is provided with a smooth, threadless bore. The winding direction of the spring is selected here in a known manner so that it tries to open in the opposite direction to its winding direction when the socket is turned to the right, ie when it is screwed onto the pipe nipple. The lower spring leg c is firmly supported in the neck of the holder, while the upper spring leg d is movable to the right and left in a small slot e in the neck of the holder.

Die Fassung läßt sich nur dann nach links abschrauben, wenn der Federschenkel d vom Rohrnippelgewinde abgehoben und dann festgehalten wird.The socket can only then unscrew the left when the spring leg d is lifted from the pipe nipple thread and then detained.
