KAISERLICHESIMPERIAL
PATENTAMT.f,PATENT OFFICE.f,
Die Erfindung bezieht sich auf Schleifstücke für Bügelstromabnehmer elektrischer Bahnen. Sie besteht darin, daß die stromabnehmende Fläche aus zweierlei - Stoffen, nämlich Metall und Kohle, gebildet ist, und zwar derart, daß das Metall den vorderen, die Kohle den hinteren Teil der am Fahrdraht anliegenden Schleiffläche bildet.The invention relates to contact strips for hoop pantographs for electrical railways. It consists in the fact that the current-taking surface is made of two materials, namely metal and carbon, is formed in such a way that the metal the front, the carbon the forms the rear part of the grinding surface resting on the contact wire.
In den Figuren sind einige Ausführungsformen der Erfindung dargestellt, und zwar im Schnitt quer durch das Schleifstück.In the figures, some embodiments of the invention are shown, namely in Cut across the contact strip.
In Fig. ι ist α die Kohle, b das Metall des die Kohle tragenden Rahmens. Das Metall hat U-Profil und die Kohle ist mit den inneren Wandungen des Metalls durch einen leitenden Kitt verbunden. Die obere Fläche des Schleifstückes ist dachförmig abgeschrägt, und zwar so, daß Kohle und Metall gemeinsam eine Schleiffläche bilden. Der in der Fahrtrichtung vordere Teil der Schleiffläche wird also von -~ ' Metall, der hintere von Kohle gebildet. Dies hat den Vorteil, daß das Feuern beim Schleifen des Bügels an der Kohle, nicht am Metall : f stattfindet. In der Richtung senkrecht zur Zeichenebene haben die Kohlenstücke beliebige Ausdehnung, die sich je nach Material und besonderem Verwendungszweck richtet.In Fig. Ι α is the coal, b the metal of the frame carrying the coal. The metal has a U-profile and the carbon is connected to the inner walls of the metal by a conductive cement. The upper surface of the contact strip is bevelled like a roof in such a way that carbon and metal together form a grinding surface. The front part of the grinding surface in the direction of travel is made of metal, the rear part of carbon. This has the advantage that the firing takes place on the coal, not on the metal: f when the hanger is ground. In the direction perpendicular to the plane of the drawing, the coal pieces have any expansion, which depends on the material and the particular purpose.
Bei der Ausführungsform nach Fig. 2 nimmt der Querschnitt der Kohle nach der Stromabnahmestelle zu in an sich bekannter Weise ab, und demgemäß sind die Seitenwandungen des Metallrahmens nicht parallel, sondern oben einander näher als unten. Die innige Verbindung zwischen Kohle und Metall kann auch hier durch leitenden Kitt herbeigeführt werden.In the embodiment of FIG. 2, the cross section of the coal takes after the Current collection point to in a known manner, and accordingly are the side walls of the metal frame not parallel, but closer together at the top than at the bottom. the Here, too, an intimate connection between carbon and metal can be brought about by conductive putty will.
Das U-Profil des Trägers für die Kohle kann auch mehrteilig sein. In Fig. 3 ist eine solche Anordnung dargestellt. Die Metallstreifen b sind an einem Träger c, der aus Metall, Holz oder sonst einem beliebigen Material bestehen kann, durch Schrauben d befestigt, während die Kohle α mit den Streifen b durch leitenden Kitt verbunden ist.The U-profile of the carrier for the coal can also be made up of several parts. Such an arrangement is shown in FIG. The metal strips b are attached to a carrier c, which can be made of metal, wood or any other material, by screws d , while the carbon α is connected to the strip b by conductive cement.
In der Anordnung nach Fig. 4 nimmt der Querschnitt der Kohle nach der Stromabnahmestelle zu ab. Durch die schräge Lage der Streifen b wird die Kohle α sehr fest im Metall gehalten.In the arrangement according to FIG. 4, the cross section of the coal decreases after the power take-off point. Due to the inclined position of the strips b , the carbon α is held very firmly in the metal.
Fig. 5 zeigt eine Anordnung, bei der die Kohle α nur seitlich von Metallstreifen b gehalten wird. In die Kohle ist an manchen Stellen ein Loch gebohrt, in welchem ein Metallrohr β mit Innengewinde liegt. In dieses Gewinde sind Schrauben d eingeschraubt, welche die Streifen b gegen die Kohle a pressen.Fig. 5 shows an arrangement in which the coal α is held only laterally by metal strips b . A hole is drilled in the coal in some places, in which a metal tube β with an internal thread is located. Screws d are screwed into this thread and press the strips b against the carbon a.
Die Fig. 6 und 7 zeigen dachförmige Schleifstücke, bei denen die Kohle durch profilierte Metallstücke gehalten wird.6 and 7 show roof-shaped contact strips in which the coal is profiled through Metal pieces is held.
In Fig. 6 sind an die Metallstreifen b Körper O1 aus gleichem Material angelötet oder die beiden Teile sind von vornherein aus einem Stück profiliert ausgeführt. Die Kohle α ruht / auf einer Platte c aus Holz oder Metall. Die äußeren, schrägen Seiten der Teile O1 werden von beliebig geformten Klammern f zusammengedrückt, die in gewissen Abständen vonein-In FIG. 6, bodies O 1 made of the same material are soldered to the metal strips b, or the two parts are profiled from the start in one piece. The coal α rests / on a plate c made of wood or metal. The outer, sloping sides of the parts O 1 are pressed together by brackets f of any shape, which are spaced apart from one another at certain
ander an dem Schleif stück des Stromabnehmers angebracht sind.other are attached to the grinding piece of the pantograph.
Bei der Ausführungsform nach Fig. 7 sind die Profilstücke b unmittelbar auf der Unterlagsplatte c verschraubt, auf welcher die Kohle α ruht.In the embodiment according to FIG. 7, the profile pieces b are screwed directly onto the support plate c on which the coal α rests.
Als Metall können beliebige Metalle, wie Aluminium, Kupfer oder deren Legierungen verwendet werden. Als besonders brauchbar hat sich Zink erwiesen.Any metal, such as aluminum, copper or their alloys can be used as the metal be used. Zinc has proven to be particularly useful.
