Description

Ernst Reiß in Düsseldorf. Die Erfindung bezieht sich auf zylindrische Kandelabermaste aus Eisenrohr. Die bisher verwendeten Maste dieser Art haben den Nachteil, daß sie den Gesetzen der Festigkeitslehre entgegen von der Einspannstelle bis zum freien Ende den gleicnen inneren und äußeren Durchmesser, also auch den gleichen Querschnitt aufweisen; um dem abzuhelfen, setzt man höhere Maste aus Rohren von verschie-Jenem Querschnitt zusammen, was jedoch mit hohen Kosten und Unbequemlichkeiten verbunden ist.Ernst Reiss in Düsseldorf. The invention relates to cylindrical Candelabra poles made of iron pipe. The masts of this type used so far have the Disadvantage that they are contrary to the laws of strength from the clamping point the same inner and outer diameter up to the free end, including the have the same cross-section; to remedy this, taller masts made of pipes are built of different cross-sections together, but what with high costs and inconvenience.

Diese Übelstände sollen nach der Erfindung dadurch verhütet werden, daß der zylindrische Kandelabermast aus einem quergeschlitzten Rohr hergestellt ist, dessen Schlitze abschnittweise an Länge zunehmen, so daß, wenn das Rohr über einen Dorn gezogen und gestreckt wird, der Durchmesser gleich dem ursprünglichen Durchmesser bleibt, die Schlitze aber zu Löchern werden, die vom Fuß des Mastes nach seiner Spitze hin abschnittweise an Weite zunehmen. Die sich um die Löcher ergebenden Stege sind, wie es im Wesen des Streckmetalls liegt, so gezogen, daß das Eisen nicht mehr zurückfedern kann. Ein so mit Löchern versehener Mast zeigt eine den Beanspruchungen besser angepaßte Stoffverteilung und setzt auch dem Wind keine geschlossenen, sondern von unten nach oben immer weiter aufgelöste Flächen entgegen, wodurch die Sicherheit des Mastes _ erhöht und seine Aufstellung erleichtert wird.According to the invention, these inconveniences are to be prevented by that the cylindrical candelabra made of a transversely slotted tube is, the slots increase in length in sections, so that when the tube is over a mandrel is drawn and stretched, the diameter equal to the original Diameter remains, but the slots become holes at the base of the mast increase in width in sections towards its tip. The ones around the holes resulting webs are, as it is in the nature of expanded metal, drawn so that the iron can no longer spring back. A mast provided with holes in this way shows a material distribution that is better adapted to the demands and also relies on the wind no closed, but from bottom to top more and more dissolved areas contrary, which increases the safety of the mast and facilitates its erection will.

Auf der Zeichnung ist ein derartiger Mast beispielsweise dargestellt.Such a mast is shown, for example, in the drawing.

Abb, i zeigt das Ursprungsrohre, weiches mit Einschnitten b versehen ist, die in den Abschnitten e, d, c von unten nach oben zunehmende Längen aufweisen; Abb. 2 zeigt einen Querschnitt A-B des vorbereiteten eingeschnittenen Rohres; Abb.3 zeigt das Rohr, wie es zu einem Gitterrohr gestreckt ist, bei dem die nach oben hin verlängerten Schlitze abschnittweise vergrößerte Löcher ergeben haben.Fig, i shows the original pipe, which is provided with incisions b which have lengths increasing from bottom to top in sections e, d, c; Fig. 2 shows a cross-section A-B of the prepared cut tube; Fig 3 shows the tube as it is stretched into a trellis tube with the upwards towards elongated slots have resulted in enlarged holes in sections.
