PATENTAMT.PATENT OFFICE.
Der Grundgedanke des Hauptpatentes läßt sich auch in zwei anderen Ausführungsformen verkörpern, die nur für zwei oder mehr Lampen Wert haben.The basic idea of the main patent can also be used in two other embodiments embody that only have value for two or more lamps.
Die Fig. 1, 2 und 3 zeigen die Anbringung von zwei Lampen an einem Schlitten a, welcher auf Gleitbahnen δ am Mast geführt wird. Beim Heraufziehen in die höchste Stellung nimmt der Schlittenständer eine lotrechte Lage dadurch ein, daß die Gleitbahn oben entsprechend abgebogen ist, so daß in dieser Stellung beide Lampen oberhalb der Mastspitze stehen und der Mast keinen Schatten werfen kann. Beim Herablassen neigt sich der Schlitten, so daß beide Lampen und der Mast in derselben Ebene bleiben wie in der Hochlage und einen möglichst schmalen Raum einnehmen.1, 2 and 3 show the attachment of two lamps to a carriage a, which is guided on slideways δ on the mast. When it is pulled up to its highest position, the slide stand assumes a vertical position in that the slide is bent at the top so that in this position both lamps are above the top of the mast and the mast cannot cast a shadow. When lowering, the carriage tilts so that both lamps and the mast remain in the same plane as in the elevated position and take up as narrow a space as possible.
Fig. 4 bis 6 zeigen eine Ausführungsform,Fig. 4 to 6 show an embodiment,
bei der die Lampen auf einem zweiarmigen Hebel befestigt sind, welcher um einen horizontalen Drehpunkt d an dem nach oben verlängerten und am Mast geführten Schlitten a schwingt. Der zweiarmige Hebel c wird durch ein Gestänge e, welches einerseits an c angelenkt ist und andererseits am Schlitten α geführt und mit einem Anschlag f versehen ist, derart bewegt, daß der doppelarmige Hebel c während des Herablassens eine vertikale Lage einimmt und beim Heraufziehen in die höchste Stellung denselben in horizontale Lage bringt, indem der Anschlag f gegen eine am Mast angebrachte Nase g stößt, so daß in dieser Stellung beide Lampen über der Mastspitze stehen, während beim Herablassen die Lampen beide vor dem Mast liegen und, wie der Grundriß (Fig. 6) zeigt, einen möglichst schmalen Raum einnehmen.in which the lamps are attached to a two-armed lever which swings around a horizontal pivot point d on the carriage a , which is extended upwards and guided on the mast. The two-armed lever c is moved by a linkage e, which is articulated on the one hand to c and on the other hand on the carriage α and is provided with a stop f , such that the double-armed lever c assumes a vertical position during lowering and when pulled up into the the highest position brings it into a horizontal position by the stop f pushing against a nose g attached to the mast, so that in this position both lamps are above the mast tip, while when lowering the lamps both lie in front of the mast and, as shown in the plan (Fig . 6) shows, occupy as narrow a space as possible.
Fig. 7 bis 9 zeigen eine ähnliche Ausführungsform, bei welcher der doppelarmige Hebel c um einen rechtwinklig zu der in vorstehendem beschriebenen Anordnung liegenden Zapfen d sich dreht.7 to 9 show a similar embodiment in which the double-armed lever c rotates about a pin d located at right angles to the arrangement described above.
