KAISERLICHES JIMPERIAL J
PATENTAMT,PATENT OFFICE,
Vorliegende Erfindung betrifft eine DynamobUrste, welche in bekannter Weise aus Lagen verschiedener Leitungsfähigkeit besteht. Bisher wurden, die verschiedenen Lagen durch einfaches Zusammensetzen von Kohlen- und Kupferplatten gebildet. Diesen Bürsten hafteten jedoch besonders wegen der verschiedenen Hilde und der dadurch bedingten verschiedenen Abnutzungsfähigkeit der Kohle und des Kupfers grofse Uebelstände an, welche bei der neuen Bürste vermieden werden sollen.The present invention relates to a dynamo brush which, in a known manner, consists of layers different levels of conductivity. So far, the different locations have been simply Composition formed by carbon and copper plates. However, these brushes particularly adhered because of the various Hilde and the resulting different wear resistance of the coal and the copper great evils, which should be avoided with the new brush.
Nach vorliegender Erfindung ist das Metall der Bürste derart mit der Kohle verbunden, dafs die einzelnen Poren der Kohle mit einem Ueberzuge aus Metall versehen werden. Zur Bildung des Metallüberzuges um die einzelnen Poren wird die Kohle in ein das betreffende Metall in fein vertheiltem Zustande enthaltendes BaJ, z. B. in eine wüsserige Silbernitratlösung eingetaucht, welche in die Kohle eindringt. Die Menge der eingedrungenen Lösung und somit auch des fein vertheilten Metalles wird von der Oberfläche der Kohlen nach dem Innern abnehmen, so dafs die einzelnen Poren der Kohle nach dem Trocknen und Erhitzen zur Entfernung der Flüssigkeit sowie der Salze mit einem feinen metallischen Ueberzug versehen sind, der in den einzelnen zur Ober-" fluche parallelen Lagen durchaus gleichmäfsig ist, von der Oberflüche nach dem Innern zu jedoch bestundig abnimmt. " ,According to the present invention, the metal of the brush is connected to the carbon in such a way that that the individual pores of the coal are provided with a coating of metal. To the Formation of the metal coating around the individual pores turns the coal into one of the pores in question BaJ containing metal in a finely divided state, e.g. B. in an aqueous silver nitrate solution immersed, which penetrates the coal. The amount of the penetrated solution and thus also of the finely divided metal is from the surface of the coals after the Remove the inside so that the individual pores of the charcoal after drying and heating to remove the liquid and the salts with a fine metallic coating are, in the individual layers parallel to the surface, quite even is, but steadily decreases from the surface towards the inside. ",
Ein besonderer Vorzug des neuen Leiters besteht noch darin, dafs die Leitungsfähigkeit des verwendeten Metalles wegen der durchaus gleichniüfsigen Vertheilung in den Poren der Kohle vollkommen ausgenutzt wird.A special advantage of the new conductor is that it is capable of conducting of the metal used because of the uniform distribution in the pores of the Coal is fully utilized.
In den beiliegenden Zeichnungen stellt Fig. 1 die Querschnittsstructur einer zur Bildung einer Bürste verwendeten Kohle dar. Fig. 2 stellt die eine Hälfte der nach der Linie a-b-c in zwei Theile zerlegten Kohle der Fig. 1 dar, während die Fig. 3 bis 5 verschiedene Arten der Zusammensetzung von Kohlenhälften zu Dynamomaschineiibürsten veranschaulichen.In the accompanying drawings Fig. 1 illustrates the Querschnittsstructur a carbon used to form a brush. Fig. 2 shows one half of the line ABC in two parts disassembled coal FIG. 1, while the Fig. 3 to 5 different Illustrate ways in which carbon halves are assembled into dynamo machine brushes.
Die Vertheilung der Zonen verschiedener Leitungsfähigkeit kann, wie Fig. 3 bis 5 der Zeichnung veranschaulicht, entsprechend abgeändert werden, indem man den in der Lösung behandelten Kohlenblock in verschiedene Lagen zerlegt und letztere dann in gewünschter Weise zusammenlegt.The distribution of the zones of different conductivity can, as Fig. 3 to 5 of the Drawing illustrated can be modified accordingly by adding the one in the solution treated coal block is broken down into different layers and the latter then in the desired manner collapses.
Die einzelnen Poren der Kohle werden durch den Metallüberzug sowohl elektrisch als auch mechanisch mit einander verbunden, so dafs ein äufserst festes widerstandsfähiges Gefüge gebildet wird. 'The metal coating makes the individual pores of the carbon both electrical and mechanically connected to one another, so that an extremely solid, resistant structure is formed. '
Die vorliegende Bürste ist besonders zum Gebrauch bei nicht umkehrbaren Dynamomaschinen geeignet und wird so in den Bürstenhalter eingesetzt, dafs der Stromwender der, Maschine auf der Oberfläche der Bürste von dem Theile höherer LeitungsUhigkeit gegen einen Theil niedrigerer Leitungsfähigkeit gleitet.The present brush is particularly suitable for use with non-reversible dynamo machines and so is placed in the brush holder used so that the commutator of the machine is on the surface of the brush of the part of higher conductivity slides against a part of lower conductivity.
