Patentirt im Deutschen Reiche vom 17. August 1886 ab.Patented in the German Empire on August 17, 1886.
Das dargestellte Schalträderwerk mit Nullstellung soll Verwendung finden bei Uhren, Umlaufzählern oder dergleichen. Fig. 1 ist die Ansicht des eingeschalteten Schaltrades mit der Vorrichtung zur Nullstellung, Fig. ia die Ansicht desselben in ausgeschaltetem Zustande, Fig. 2 die Ansicht desselben in ausgeschaltetem Zustande während der Nullstellung.The illustrated ratchet mechanism with zero position is intended to be used for clocks, Circulation counters or the like. Fig. 1 is the view of the switched ratchet with the Device for zero position, Fig. Ia the view of the same in the switched-off state, 2 shows the view of the same in the switched-off state during the zero position.
Der Sperrhebel C sitzt auf einer Welle a, welche in einem im Punkt d drehbaren Hebel, D gelagert ist. Dreht man den Hebel nach unten, so wird, wie aus Fig. 2 ersichtlich, der Sperrhebel c aufser Eingriff mit der Antriebscheibe A und dem Zahnrad B gebracht, wonach beide frei gedreht werden können, bis die Nullstellung eingetreten ist.The locking lever C sits on a shaft a which is mounted in a lever D rotatable at point d. If the lever is rotated downwards, as can be seen from FIG. 2, the locking lever c is brought into engagement with the drive pulley A and the gear wheel B , after which both can be rotated freely until the zero position is reached.
Der Hebel D ist noch mit einem zweiten Arm E versehen, welcher beim Senken des Armes D in den Einschnitt α der auf dem Schaltrad B angebrachten Herzscheibe greift und in dieser Stellung verharrt, bis der Arm D zurückgedreht wird und der Sperrhebel C wieder mit dem Schaltrad B und der Antriebscheibe A in Berührung kommt.The lever D is also provided with a second arm E , which, when the arm D is lowered, engages in the incision α of the heart disk attached to the ratchet wheel B and remains in this position until the arm D is turned back and the locking lever C again with the ratchet wheel B and the drive pulley A comes into contact.
Die Antriebscheibe A hat an ihrem Umfange den Einschnitt m und den Schubzahn xr. Letzterer greift in die Zahnscheibe B und dreht dieselbe um einen Zahn weiter, während der Ansatz yλ des Sperrhebels c in den Einschnitt m greift und dadurch bewirkt, dafs das Rad B für eine Zeit, welche der Länge des Einschnittes m entspricht, frei wird.The drive pulley A has the incision m and the thrust tooth xr on its circumference. The latter engages in the toothed disk B and rotates it by one tooth, while the extension y λ of the locking lever c engages in the incision m and thereby causes the wheel B to be free for a time corresponding to the length of the incision m.
