Description

Federnder Schleifkontakt für elektrische Lokomotiven. Bekanntlich wird der Strom für elektrische Lokomotiven von den Fahrdrähten durch federnde Schleifkontakte mit auswechselbarem I,7,upferbügel abgenommen. Durch die bestehenden Höhendifferenzen in der Fahrleitung wird der Schleifkontakt selbsttätig je nach der Fahrtrichtung nach vorn oder rückwärts umgelegt und behält dabei immer einigermaßen den gleichen Anpressungsdruck an den Fahrdraht. Durch das Reiben des Kupferbügels an dem Fahrdraht schleift sich das Kupfer allmählich ab, bis schließlich, sofern für rechtzeitigen Ersatz nicht gesorgt wird, der Bügel an der meistabgenutzten Stelle durchreißt oder durchbrennt. Die nunmehr frei stehenden Hälften des Bügels schlagen dann über den Fahrdraht. Die noch im Schwunge befindliche Lokomotive reißt durch die Bügelenden oft ganze Strecken der Oberleitung herunter, oder zum mindesten werden Teile derselben stank verletzt. Ebenso kommt es -vor, daß der Schleifbügel nochin gutem Zustand an einem .defekten Isolator o. 'dgl. hängenbleibt, wodurch dann größere Zerstörungen eintreten.Spring-loaded sliding contact for electric locomotives. As is well known the electricity for electric locomotives is supplied by the contact wires through resilient sliding contacts with exchangeable I, 7, copper bar removed. Due to the existing height differences in the catenary, the sliding contact is automatic depending on the direction of travel folded forwards or backwards and always remains somewhat the same Contact pressure on the contact wire. By rubbing the copper bracket on the contact wire The copper gradually grinds off until finally, provided for timely Replacement is not provided, the bracket tears at the most worn point or blows. The now free-standing halves of the bracket then hit over the Contact wire. The locomotive, which is still swinging, tears through the ends of the stirrups often entire stretches of the overhead line, or at least at least will Parts of it stank injured. It also happens that the grinding hanger is still in good condition on a defective isolator or the like. gets stuck, which then makes larger Destruction occurs.

Diese Mängel werden durch den Schleifbügel gemäß der nachstehend beschriebenen und gezeichneten Erfindung beseitigt.These deficiencies are addressed by the abrasive hanger as described below and subscribed invention eliminated.

Damit der Schleifbügel nach dem Durchreiben nicht mehr frei stehend bleibt, sondern seine Hälften sofort nach außen fallen, sind die Kupferbügelenden nicht in dem in der Grundplatte i durch die Zapfen 2 gelagerten Federspannstück 3 unmittelbar befestigt, sondern es sind Gelenkstücke 4 eingefügt und in diesen die Kupferbügelenden festgeklemmt. Die Blattfedern 5 dienen einerseits zur besseren elektrischen Verbindung, andererseits sollen sie beim Bruch des Kupferbügels 6 die Hälften schnell nach außen drücken; außerdem sorgt das Eigengewicht des oberhalb des Drehgelenkes 7 befindlichen Gelenkstückes 4 für ein selbsttätiges Herunterfallen. Die punktierte Darstellung veranschaulicht die herabgefallenen- Teile. Selbstverständlich kann die Einrichtung auch so getroffen werden, daß die Gelenkstücke mit den Kupferenden nicht nach außen, sondern nach innen fallen. Ferner ist das Gelenkstück 4 für die Kupferbügelbefestigung so ausgebildet, daß die Feststellschrauben $ auf eine sogenannte Zunge 9 drücken und diese den Kupferdraht nur so festhält, daß durch ein Hindernis an der Oberleitung der Bügel herausgezogen wird. Statt dieser Kupferbügelbefestigung mittels Feststellschraube -8 und Zunge 9 ist in Abb.2 eine Konstruktion dargestellt, in welcher der Kupferbügel 6 durch eine Druckfeder io festgehalten wird.So that the sanding hanger is no longer free-standing after being rubbed through remains, but its halves immediately fall outwards, are the copper bracket ends not in the spring clamping piece mounted in the base plate i by the pin 2 3 attached directly, but there are joint pieces 4 inserted and in these the copper bracket ends clamped. The leaf springs 5 serve on the one hand for better electrical connection, on the other hand they should break the copper bracket 6 the Quickly push halves outwards; in addition, the dead weight of the above ensures of the swivel joint 7 located joint piece 4 for an automatic fall. The dotted line illustrates the fallen parts. Of course the device can also be made so that the joint pieces with the copper ends not falling outwards, but falling inwards. Furthermore, the joint piece 4 is for the Copper bracket attachment designed so that the locking screws $ on a so-called Press tongue 9 and this only holds the copper wire so that through an obstacle the bracket on the overhead line is pulled out. Instead of this copper bracket attachment by means of locking screw -8 and tongue 9, a construction is shown in Figure 2, in which the copper bracket 6 is held in place by a compression spring io.

PATENT-ANsPRUcH: Federnder Schleifkontakt mit leicht auswechselbarem Kupferbügel für elektrische Lokomotiven, dadurch gekennzeichnet, daß nach dem Durchschleifen oder Herausziehen des Kupferbügels die dann frei stehenden Hälften sofort auseinanderfallen und hierdurch außerhalb des Bereichs der Fahrleitung kommen. PATENT CLAIM: Spring-loaded sliding contact with easily exchangeable copper bracket for electric locomotives, characterized in that after the copper bracket has been looped through or pulled out, the halves that are free then fall apart immediately and thus come outside the area of the catenary.
