Diese Erfindung bezieht sich auf Neuerungen an Vorrichtungen zum Heben und Niederlassen der verschiebbaren Theile bei Gas- und anderen Kronenleuchtern.This invention relates to innovations in lifting and lowering devices the sliding parts of gas and other chandeliers.
Beiliegende Zeichnung stellt einen Verticalschnitt der Vorrichtung in ihrer Anwendung auf Kronenleuchtern dar. α ist das Gewinde am unteren Ende (es kann auch am oberen Ende angeordnet werden) eines Rohres oder einer Stange b, welches in ein entsprechendes Gewinde oder eine spiralförmige Rinne in der Innenfläche der Hülse oder Mutter c pafst. Das mittlere Rohr b geht durch das Gehäuse d hindurch und ist daselbst mit einer Spiralfeder e verbunden.The accompanying drawing shows a vertical section of the device in its application to chandeliers. Α is the thread at the lower end (it can also be arranged at the upper end) of a tube or rod b, which is inserted into a corresponding thread or a spiral groove in the inner surface the sleeve or nut c pafst. The middle tube b passes through the housing d and is connected there to a spiral spring e .
Das Gehäuse d nebst Zubehör wird an der Decke des Zimmers oder des Gebäudes, wie üblich, durch Kugelgelenk oder auf andere passende Weise befestigt. Das mittlere Rohr bezw. die Stange b ist von einem zweiten Rohr/ umgeben, welches das Gleitrohr der Gaskrone oder das- Tragerohr des Candelabers bildet und mit länglichen Schlitzen g versehen ist; in letztere greifen die Vorsprünge h ein.The housing d together with accessories is attached to the ceiling of the room or building, as usual, by means of a ball joint or in another suitable manner. The middle pipe respectively. the rod b is surrounded by a second tube / which forms the sliding tube of the gas crown or the support tube of the candelabra and is provided with elongated slots g ; the projections h engage in the latter.
Diese Vorsprünge h sind mit der Hülse oder Mutter c verbunden, um letztere am Drehen zu verhindern.These projections h are connected to the sleeve or nut c to prevent the latter from rotating.
Wird die Hülse c des Kronenleuchters nach unten gezogen, so verursacht das innere ' Gewinde derselben eine Drehung des inneren Rohres b mittelst des Gewindes a, wodurch die Feder e im Gehäuse d aufgewunden wird. Beim Heben der Hülse c tritt die Feder e in Wirkung und zwingt das mit Gewinde α versehene Rohr b, sich in entgegengesetzter Richtung, wie oben beschrieben, zu drehen, so dafs der erforderliche Handdruck zum Heben der Krone so vermindert wird, dafs keineswegs mehr Kraft erforderlich ist, wie dies bei Anwendung von Gewichten der Fall ist.If the sleeve c of the candlestick is pulled down, the inner thread of the same causes a rotation of the inner tube b by means of the thread a, whereby the spring e is wound up in the housing d. When lifting the sleeve c occurs, the spring e in effect, forcing the α threaded pipe b to rotate in the opposite direction, as described above; so that the required hand pressure for lifting the crown is reduced so as not DAF strength is required, as is the case with the use of weights.
Man kann auch die Hülse c an der Decke befestigen und das Gleitrohr / hinaufschieben oder niederziehen.You can also attach the sleeve c to the ceiling and slide the sliding tube / up or down.
Bei Gaskronen geschieht die Gaszuführung durch ein drittes Rohr i, welches durch das mittlere Rohr und durch eine Stopfbüchse am unteren Ende desselben hindurch geht.In the case of gas crowns, the gas is supplied through a third pipe i, which goes through the middle pipe and a stuffing box at the lower end of the same.
