PATENT. ANSPR OOHE : 1. Einrichtung zum Nachspannen dar Fahrleitung elektrischer Bahnen, die an einem Tragsei ! mittels Hangedrähte aufgehängt ist, unter Verwendung eines Gewichts oder einer Feder, dadurch gekennzeichnet, dass die Nachspannung sich nur über eine solche Anzahl von Spannweiten erstreckt, dass die im tiefsten Punkte der Kettenlinie befestigten Hängedrähte, welche eine Länge von mindestens 20 cm aufweisen, bei ihrer Bewegung aus der senkrechten Lage eine Neigung von 30 nicht überschreiten, PATENT. REQUIREMENTS: 1. Device for re-tensioning the catenary of electric railways that are attached to a supporting rope is suspended by means of hanging wires, using a weight or a spring, characterized in that the post-tensioning extends only over such a number of spans that the hanging wires attached at the lowest point of the chain line, which have a length of at least 20 cm, at their Movement from the vertical position does not exceed an incline of 30, so dass auch bei unverschieb- barer Anordnung der Aufhängepunkt für das Tragseil und bei festen Verbindungspunkten zwischen den Hängedrähten einerseits und dem Tragseile und der Fahrleitung andererseits eine ausreichende Nachspannung der Fahrleitung durch einfaches Schrägstellen der Hängedrähte erzielbar ist. so that even with an immovable arrangement of the suspension point for the suspension cable and with fixed connection points between the suspension wires on the one hand and the suspension cables and the catenary on the other hand, sufficient tensioning of the catenary can be achieved by simply tilting the suspension wires. 2. Einrichtung nach Anspruch l, dadurch gekennzeichnet, dass die Bewegung des Spanngewichts oder der Spannfeder derartig beschränkt ist, dass ein Abbiegen der Hängedrähte über das angegebene Mass auf jeden Fall verhindert wird. EMI2.1 2. Device according to claim l, characterized in that the movement of the tension weight or the tension spring is limited in such a way that bending of the hanging wires beyond the specified extent is prevented in any case.
