Bei der Ausführung der Vielfachaufhängung für die Fahrleitung (sogenannte Kettenoberleitung) elektrischer Bahnen hat es sich herausgestellt, daß es nicht möglich ist, die Zugspannung im Fahrdraht bei dessen direkter Befestigung an der Tragleitung in solchen Grenzen zu halten, wie es für eine stetige Stromabnahme ohne Funkenbildung notwendig ist, weil durch die TemperaturschwankungenWhen executing the multiple suspension for the overhead contact line (so-called chain overhead line) electrical railways it has been found that it is not possible to reduce the tension in the contact wire when it is directly attached to the support line to be kept within such limits as is a constant Power consumption without sparking is necessary because of the temperature fluctuations
ίο beträchtliche Längenänderungen des Fahrdrahtes auftreten, durch die ein mehr oder minder großer Durchhang der Leitungen verursacht wird.ίο considerable changes in length of the contact wire occur that cause a more or less large slack in the cables will.
Um die Leitungen stets straff gespannt zu erhalten, ist es deshalb notwendig, selbsttätig wirkende Nachspannvorrichtungen zu verwenden, doch bedingen diese, daß der Kontaktdraht verschiebbar an dem Tragdraht befestigt wird. Eine derartige Einrichtung von ein-In order to keep the lines taut at all times, it is therefore necessary to do this automatically Acting tensioning devices to be used, but these require that the contact wire is slidably attached to the support wire.

ao fächer Bauart bildet nun den Gegenstand der vorliegenden Erfindung.ao fan design now forms the subject of the present invention.
Auf beiliegender Zeichnung stellt Fig. 1 einen Teil der Aufhängung in Ansicht dar. Fig. 2 zeigt eine Einzelheit der Aufhängung.In the accompanying drawing, Fig. 1 shows a part of the suspension in a view. Fig. 2 shows a detail of the suspension.
An dem Tragseil a, dessen Neigung gegen die Horizontale an den einzelnen Aufhängepunkten durch die in ihm auftretenden Spannungen bedingt wird, ist ein Eisenstab c mittels Laschen b, e oder in sonstiger Weise derart befestigt, daß durch die Verwendung einer Kette d zwischen Lasche e und Stab c letzterer nachstellbar in wagerechter Lage gehalten wird. Auf diesen Eisenstab c ist eine Hülse f aufgeschoben, die an ihrem unteren Ende als Klemmvorrichtung g ausgebildet ist, an welcher ein Stahldraht h fest oder in senkrechter Richtung verstellbar angeordnet ist. An iron rod c is attached to the support cable a, whose inclination to the horizontal at the individual suspension points is caused by the stresses occurring in it, by means of straps b, e or in some other way in such a way that the use of a chain d between strap e and Rod c the latter is held adjustably in a horizontal position. A sleeve f is pushed onto this iron rod c, which is designed at its lower end as a clamping device g , on which a steel wire h is arranged fixedly or displaceably in the vertical direction.
Der Stahldraht h trägt an seinem unteren Ende eine Klemme i, an der der Kontaktdraht k befestigt wird. Die Hülse f ist auf dem Eisenstab c verschiebbar angeordnet, so daß sie den Bewegungen des Kontaktdrahtes k folgen kann. Wenn der Stahldraht h in der Höhe verstellbar angeordnet ist, wird ein späteres genaues Einstellen des Fahrdrahtes in senkrechter Richtung ermöglicht.The steel wire h carries at its lower end a clamp i to which the contact wire k is attached. The sleeve f is slidably arranged on the iron rod c so that it can follow the movements of the contact wire k. If the height of the steel wire h is adjustable, a later precise adjustment of the contact wire in the vertical direction is made possible.
