PATENTSCHRIFTPATENT LETTERING

KLASSE 63: Sattlerei und Wagenbaü.CLASS 63: Saddlery and wagon construction.

Patentirt im Deutschen Reiche vom 23. Oktober 1896 ab.Patented in the German Empire on October 23, 1896.

Den Gegenstand vorliegender Erfindung bildet eine Ausführungsform einer solchen Vorrichtung zur Aenderung der Uebersetzung bei Fahrrädern, bei denen mit der Tretkurbelwelle ein Zahnrad verbunden ist, welches in oder aufser Eingriff mit einem am Kettenrade befindlichen' Zahnrade gebracht werden kann.The subject of the present invention is an embodiment of such a device to change the translation for bicycles, which have a pedal crankshaft Gear is connected, which is in or out of engagement with a 'located on the chain wheel' Gear can be brought.

Auf beiliegender Zeichnung ist die Antriebvorrichtung zur Darstellung gebracht; es zeigt:The drive device is shown in the accompanying drawing; it shows:

Fig. ι in Seitenansicht die Vorrichtung,'wie sie zum Befahren einer Anhöhe benutzt wird, undFig. Ι in side view the device, 'how it is used to climb a hill, and

Fig. 2 einen Schnitt nach Linie x-x der Fig. ι, wobei sich die Vorrichtung in der Stellung für normale Geschwindigkeit des Rades befindet.Fig. 2 is a section along line xx of Fig. Ι, wherein the device is in the position for normal speed of the wheel.

Die Vorrichtung besteht aus dem Kettenrad a, mit welchem ein mit einer Verzahnung versehenes Zahnrad b fest verbunden ist. Letzteres steht mit dem Zahnrad c in Eingriff, welches auf der Welle d fest angeordnet ist, wobei die Tretkurbel e auf der Welle d mittelst Schraubenbolzens f verstellt werden kann, während die Kurbel e fest auf ihr sitzt. Die Speichen g des Kettenrades α tragen das Zahnrad b, das auf seinem ä'ufseren Umfang mit Nuthen h versehen ist. Das Kettenrad α lagert mittelst Kugeln k auf der in ihrer Längsrichtung excentrisch durchbohrten Achse i. In dieser Bohrung befindet sich die Kurbelwelle d, die etwas länger als die Achse i ist.The device consists of the chain wheel a, to which a toothed wheel b is firmly connected. The latter is in engagement with the gear c , which is fixedly arranged on the shaft d, wherein the pedal crank e can be adjusted on the shaft d by means of screw bolts f , while the crank e sits firmly on it. The spokes g of the chain wheel α carry the gear wheel b, which is provided with grooves h on its outer circumference. The chain wheel α is supported by means of balls k on the axis i, which is eccentrically bored through in its longitudinal direction. The crankshaft d, which is slightly longer than the axis i , is located in this bore.

Die Kurbel besitzt eine Oeffnung Z, deren Breite dem einfachen und deren Länge ungefähr dem doppelten Durchmesser der Achse d entspricht; durch diese Oeffnung / geht der Schraubenbolzen/, welcher in die mitSchraubengewinde versehene Achse d geschraubt wird und die Kurbelstange e mit der Achse d verbindet. Die Kurbelstange e hat an ihrem unteren Theil einen Zapfen m erhalten, welcher in die Nuthen h des Zahnrades b zu greifen vermag.The crank has an opening Z, the width of which corresponds to the single diameter and the length of which corresponds approximately to twice the diameter of the axis d; The screw bolt /, which is screwed into the screw-threaded axis d and connects the connecting rod e to the axis d, passes through this opening. The lower part of the connecting rod e has a pin m which is able to engage in the grooves h of the gear wheel b.

Der Schraubenbolzen f bewegt sich in der Oeffnung I der Kurbelstange e und bewirkt durch seine Bewegung, dafs die mit ihm verschraubte Achse d in der Aussparung / steigt oder sinkt.The screw bolt f moves in the opening I of the connecting rod e and, through its movement, causes the axis d screwed to it in the recess / to rise or fall.

Die Wirkungsweise der Vorrichtung ist folgende:The device works as follows:

Wenn Steigungen überwunden werden sollen, befindet sich die Kurbelachse d im unteren Theil der Oeffnung I, wie Fig. 1 zeigt, wobei Tretkurbel e das Zahnrad c und dieses das Zahnrad b mit dem Kettenrad a in Drehung versetzt. Das Kettenrad läuft auf den Stahlkugeln k, während die Achse i unbeweglich bleibt.When gradients are to be overcome, is the crank shaft d in the lower portion of the opening I, as shown in Fig. 1, wherein the pedal crank e c, the gear and the gear of this offset b with the sprocket in a rotation. The chain wheel runs on the steel balls k, while the axis i remains immobile.

Soll nun normale Geschwindigkeit eintreten, z. B. auf wenig ansteigendem Boden, so wird der Schraubenbolzen f so lange gedreht, bis der Zapfen m (Fig. 2) in die Nuth h gebracht ist, wobei die Kurbelstange e mit dem Zahnrad b und Kettenrad a direct starr verbunden ist und eine gröfsere Geschwindigkeit erzeugt wird wie vorher.Should now normal speed occur, z. B. on slightly rising ground, the screw bolt f is rotated until the pin m (Fig. 2) is brought into the groove h , the connecting rod e is directly rigidly connected to the gear wheel b and chain wheel a and a larger one Speed is generated as before.
