Description

Mechanisches Schaltwerk für Steuerwalzen. Es ist bekannt geworden, eine Steuerwalze durch ein infolge eines Hemmwerks, sei es ein Flügelwerk oder eine Ölpumpe, allmählich herunterfallendes Gewicht zu schalten. Diese Schaltung kann aber nur eine über die Widerstandsstufen der Steuerwalze hinweggehende schleichende sein. Da das die Schaltung herbeiführende Gewicht noch dazu immer dann etwas schneller fällt, wenn es weniger Arbeit, etwas langsamer, wenn es mehr Arbeit zu überwinden hat, so tritt gerade der übelstand auf, daß, wenn die Hämmer der Steuerwalze auf die Kontaktbeläge, also auf eine neue Schaltstellung, übergehen wollen, eine langsame Bewegung vorliegt. Dadurch tritt eine große Abnutzung der Kontaktbeläge und der Kontaktklötze an den Hämmern durch starkes Schmoren ein.Mechanical switching mechanism for control rollers. It has become known a control roller by a result of an escapement, be it a wing or a Oil pump to turn on gradually falling weight. This circuit can but only a creeping over the resistance levels of the control drum be. Since the weight causing the shift is always a bit faster falls when there is less work, something slower when there is more work to be overcome has, then just the evil occurs that when the hammers of the control drum on want to move the contact coatings, i.e. to a new switch position, a slow one There is movement. This causes a great deal of wear and tear on the contact pads and the Contact blocks on the hammers by strong braising.

Das neue Schaltwerk vermeidet jedoch diesen Übelstand, indem es eine Drehung des Kontrollers derartig herbeiführt, daß der Kontroller von Kontaktstufe zu Kontaktstufe springt.However, the new rear derailleur avoids this drawback by providing a Rotation of the controller brings about that the controller of contact level jumps to contact level.

Die Zeichnung zeigt in Abb. i und 2 beispielsweise eine Ausführung dieses neuen Schaltwerkes.The drawing shows an embodiment in Figs. I and 2, for example this new rear derailleur.

Zur Schaltung wird das Gegengewicht a, auf einer Zahnstange b liegend, in die punktierte Höchstlage gelegt. Zum Schalten fällt die Zahnstange b, deren Bewegung durch das Hemmwerk mit dem 'Windflügel c gebremst wird, langsam herunter. Die Bewegung der Zahnstange b wird auf ein Zahnrad d übertragen. Mit dem Zahnrad d ist durch eine Klinke e das Nockenrad f verbunden. Bei der Drehung des Zahnrades d dreht sich also auch das N ockenrad f, und dadurch wird der Hebel g jedesmal über die Nocken des Rades i hinweggehoben, worauf dann der Hebel g unter seinem Gewicht h plötzlich herunterfällt und dadurch vermittels der Klinke! die Steuerwalze k weiterdreht.To switch the counterweight a, lying on a rack b, is placed in the dotted maximum position. To switch the rack b, the movement of which is braked by the escapement with the wind blade c, slowly falls down. The movement of the rack b is transmitted to a gear d . The cam wheel f is connected to the gear wheel d by a pawl e. When the gear wheel d rotates, the cam wheel f also rotates, and as a result, the lever g is lifted each time over the cams of the wheel i, whereupon the lever g suddenly falls under its weight h and thereby by means of the pawl! the control drum k continues to rotate.

PATENTANSPRUCH: Mechanisches Schaltwerk für Steuerwalzen, die durch ein infolge eines Hemmwerks allmählich herunterfallendes Gewicht fortgeschaltet werden, dadurch gekennzeichnet, daß die schleichende Bewegung des herunterfallenden Gewichtes durch ein Nockenrad auf einen Hebel übertragen wird, der durch die Nocken absatzweise hochgehoben frei wieder herunterfällt und durch jede dieser Fallbewegungen die Steuerwalze um eine Schaltstufe weiterreißt. PATENT CLAIM: Mechanical switching mechanism for control rollers, which are advanced by a weight gradually falling down as a result of an inhibiting mechanism, characterized in that the creeping movement of the falling weight is transmitted by a cam wheel to a lever which, when lifted up by the cams, falls freely down again and through each one this falling movements tears the control drum by one switching step.
