Elektrische Spielzeugeisenbahn. Patentiert im Deutschen Reiche vom 25. März 1906 ab. Electric toy train. Patented in the German Empire on March 25, 1906.

Gegenstand der Erfindung ist eine elektrische Spielzeugeisenbahn, bei der die Fahrtrichtung nach jeder Stroinunterbrechung selbsttätig geändert wird, ohne daß eine Änderung der Stromrichtung im Schienenwege erforderlich wäre. Dies geschieht dadurch, daß eine in zwei Teile geteilte Feldmagnetwicklung mit ihrem Teilpunkt an einen Motor und mit ihren Enden an einen Umschalter angeschlossen ist, der bei jedesmaligem öffnen und Schließen des Stromkreises die Stromrichtung in der Wicklung des Feldmagneten und damit die Fahrtrichtung umkehrt, ohne daß die Stromrichtung im Schienenwege geändert wird.The invention relates to an electric toy train in which the direction of travel is automatically changed after each stroke interruption without a change the direction of the current in the railways would be required. This is done by having a field magnet winding divided into two parts with their partial point to a motor and with their ends to a changeover switch is connected, which opens and closes the circuit every time reverses the direction of current in the winding of the field magnet and thus the direction of travel without changing the direction of the current in the railways is changed.

Die Zeichnung stellt in Fig. 1 und 2 ein Ausführungsbeispiel eines mit dem Umschalter nach Maßgabe der Erfindung ausgerüsteten Fahrzeugs in Vorder- und Seitenansieht dar; Fig. 3 zeigt das Schaltungsschema der Bahnanlage.The drawing shows in Figs. 1 and 2 an embodiment of one with the changeover switch vehicle equipped according to the invention in front and side views dar; Fig. 3 shows the circuit diagram of the railway system.

Wie aus der Zeichnung ersichtlich, ist die Wicklung des Feldmagneten \ dadurch in zwei Abschnitte zerlegt, daß an den etwa in der Mitte liegenden Trennungspunkt i die nach der Stromwandlerbürste / des Motorankers y führende Leitung 4 angeschlossen ist. Der Motoranker ist von unveränderlicher Polarität und durch den an die Bürste k angeschlossenen Stromabnehmer 3 an die Stromzuführungsschiene 2 gelegt. Die beiden Pole g, h der Feldmagnetwicklung \ stehen durch die Leitungsdrähte 6, 7 mit den Stromschlußfedern a, b eines in das Fahrzeug eingebauten Umschalters in Verbindung, die ange-As can be seen from the drawing, the winding of the field magnet \ is divided into two sections by connecting the line 4 leading to the current transformer brush / motor armature y to the separation point i, which is approximately in the middle. The motor armature has an invariable polarity and is connected to the power supply rail 2 by the current collector 3 connected to the brush k. The two poles g, h of the field magnet winding \ are connected by the lead wires 6, 7 to the circuit springs a, b of a changeover switch built into the vehicle.

der aus dem mittels Drahtes 5 an
Stromzu- und -rückleitung 3 und
schlossenen Elektromagneten m mit um einen Drehzapfen d pendelnden Anker ρ und einem Sperrgetriebe für das Stromschlußstück besteht. Dieses setzt sich aus einem Sperrrade e und einem mit ihm auf gleicher Achse f sitzenden Sternrade c als Stromschlußstück und einem am pendelnden Anker ρ sitzenden Sperrkegel η zusammen, der durch eine Feder mit den Zähnen des Sperrrades e in Eingriff gehalten wird. Das Kontaktstück c, welches durch Leitung 8 mit den als Rückleitung dienenden Fahrschienen 1 verbunden ist, hat halb soviel wie das Sperrrad e, so daß seine Zahnteilung etwa dem Doppel der Sperrzahnteilüng entspricht; außerdem sind die Stromabgabefedern a,b so lang und derartig angeordnet, daß, sobald ein Zahn des Sperrades gegen die eine Feder schleift, die andere Feder mit ihrem Endteil in eine Zahnlücke des Sternrades c eintritt, so daß bei jedesmaliger Drehung des Sperrrades e um einen Zahn die Stromabgabefedern a, b abwechselnd zur Herstellung des Stromschlusses in Wirkung treten.from the by means of wire 5 on
Power supply and return line 3 and
closed solenoid m with about a pivot d oscillating armature and ρ is a locking gear for the power-circuit piece. This consists of a ratchet wheel e and a star wheel c seated on the same axis f as a current connection piece and a locking cone η seated on the oscillating armature ρ , which is held in engagement with the teeth of the ratchet wheel e by a spring. The contact piece c, which is connected by line 8 to the running rails 1 serving as a return line, has half as much as the ratchet wheel e, so that its tooth pitch corresponds approximately to twice the ratchet pitch; Furthermore, the current output springs a, b so long and arranged such that when a tooth of the ratchet wheel against which a spring loops, enters the other spring with its end portion in a tooth gap of the star wheel c so that with each repeated rotation of the ratchet wheel e a Tooth, the current output springs a, b alternately come into effect to produce the current connection.

Wird nun durch einen zwischen Stromquelle und Fahrbahn befindlichen (nicht dargestellten) Ausschalter beliebiger Ausführung Stromschluß hergestellt, so wird der Anker ρ von dem erregten Elektromagneten m angezogen, wie punktiert angedeutet ist.If a circuit breaker of any design located between the power source and the roadway (not shown) is now connected to the current, the armature ρ is attracted by the energized electromagnet m , as indicated by dotted lines.

Es soll angenommen werden, daß hierdurch der Sternkontakt c in die durch Fig. 3 dargestellte Lage übergeführt ist, inIt should be assumed that the star contact c is thereby converted into the position shown by FIG. 3, in

which grinds the spring α against one of its teeth, but the spring b is out of engagement with the teeth of the contact c. The current flows from the power supply line 2 through the current collector 3, the brush k, the armature of the motor y, the brush / and passes from here through the wire 4 to the separation point i of the field magnet winding ^. This is traversed by the current in the direction of the arrow I, which passes through the line 6 into the current circuit spring α and is transferred from here through the star contact c and the line 8 into the rail return line. If the current is now interrupted, the armature ρ of the switch falls back under its own weight into the position shown in solid lines in Fig. 3, the deflection of the pendulum oscillations being measured in such a way that the pawl η is returned by one tooth pitch on the ratchet e. If the current is then closed again, the armature ρ is again attracted by the electromagnet m connected to the secondary line 5, whereby the ratchet wheel e is advanced by one tooth and at the same time the star contact c is advanced by half a tooth pitch, with the effect that the Spring a, entering a tooth gap, comes out of contact with it, while the star contact placed on the rail return line 8 is conductively connected to the field magnet winding \ by touching the star wheel c with the spring b. The current, which also flows through the motor armature and its brushes k, I and the lines 2, 3 and 4 directly connected to it in the same direction as before, with this switching method, emerges from the separation point i through the winding of the field magnet ^ in the opposite direction as before (arrow direction II) and is then transferred into the rail return line 8, 1 through line 7, contact spring b and contact piece c. This change in the direction of current in the field magnet has the effect that the motor armature, which retains the same polarity in both circuit types, rotates in the opposite direction as before and thus changes the direction of travel without changing the direction of the current in the railways.
