Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der Gegenstand vorliegender Erfindung ist eine Ausführungsform des Geschwindigkeitsmessers nach Patent 179775.The subject of the present invention is an embodiment of the speedometer according to patent 179775.

Während bei dem Geschwindigkeitsmesser nach dieser Erfindung der bewegliche Leiter eine rechteckige Platte ist, die sich tangential, aber geradlinig an den Polen des Magnetrades fortbewegt, ist bei der vorliegenden Erfindung der bewegliche Leiter in an sich bekannter Weise zu einer Kreisscheibe ausgebildet, welche sich zwar auch tangential zu den Polen des Magnetrades, aber nicht geradlinig bewegt, sich vielmehr um eine durch ihren Mittelpunkt gehende, zu ihr senkrechte und mithin auch zur Achse des Magnetrades senkrechte Achse dreht.While in the speedometer of this invention, the movable conductor is a rectangular plate that is tangential but rectilinear to the poles of the magnetic wheel moved, in the present invention the movable conductor is designed in a manner known per se to form a circular disk, which is also tangential to the poles of the magnetic wheel, but not in a straight line rather moves around a center that runs through its center and is perpendicular to it and therefore also rotates an axis perpendicular to the axis of the magnet wheel.

Die Vorrichtung ist auf der Zeichnung in der Fig. 1 und 2 in zwei zueinander senkrechten Achsenschnitten, in der Fig.. 3 inThe device is on the drawing in Figs. 1 and 2 in two mutually perpendicular Axial sections, in the Fig. 3 in

ao Ansicht von oben und in der Fig. 4 in einem Grundriß, aber mit fortgedachtem Zifferblatt, • und in teilweisem Schnitt dargestellt.ao view from above and in FIG. 4 in one Ground plan, but with an advanced dial, • and shown in partial section.

Wie bei dem Gegenstand des Hauptpatentes liegt tangential zu dem Pol 5 eines Magnetrades 4 eine ebene Platte 6 aus leitendem Material. Sie ist aber nicht rechteckig, sondern kreisförmig und wird von der Achse 26 getragen, die in einem Bügel 27 in Spitzen gelagert ist. Der Bügel ist seinerseits im Gehäuse 28 bei 29 befestigt. Bei der Drehung des Magnetrades wird daher ebenfalls eine Drehung der Scheibe 6 erfolgen. Die vollkommene Drehung, d. h. ein Mitlaufen der Scheibe 6 und der Welle 26 wird durch eine Spiralfeder 35 verhindert, die einerseits an der Achse, andererseits an einem Ansatz 31 des Bügels befestigt ist. . Das Maß der Verdrehung der Scheibe 6 und der Welle 26 wird auf einem Zifferblatt 32 mit entsprechender Skala durch einen Zeiger 33 kenntlich gemacht, der mit der Achse 26 und der Scheibe 6 durch ein Verbindungsstück 34 in Verbindung steht, welches das Zifferblatt durch ein zentrales Loch durchdringt.As with the subject matter of the main patent is tangential to the pole 5 of a magnetic wheel 4 a flat plate 6 made of conductive material. But it is not rectangular, it is circular and is carried by the axis 26, which in a bracket 27 in points is stored. The bracket is in turn fastened in the housing 28 at 29. When turning of the magnet wheel, a rotation of the disk 6 will therefore also take place. The perfect one Rotation, d. H. running of the disk 6 and the shaft 26 is prevented by a spiral spring 35, which on the one hand the axis, on the other hand, is attached to a shoulder 31 of the bracket. . The amount of twist the disk 6 and the shaft 26 are identified by a pointer 33 on a dial 32 with a corresponding scale made connected to the axle 26 and the disc 6 by a connector 34 in Connection stands, which penetrates the dial through a central hole.

Bei dieser Ausführungsform ist daher der Vorteil einer einfachen und dabei doch sicheren Führung des bewegten Leiters und einer Verkürzung der Skala bezw. der Verkürzung der ganzen Vorrichtung erreicht.In this embodiment, therefore, the advantage of a simple and yet safe Leadership of the moving conductor and a shortening of the scale BEZW. the shortening of the whole device achieved.
