Description

Uhr mit Haupt- und Nebenfeder Einrichtungen, welche geeignet sind, 'den Ein-Ruß einer ungleichmäßigen Antriebskraft, z. B. einer Federoder gegebenenfalls auch eines Motors, auf den Gangregler eines Laufwerkes herabzusetzen, sind bekannt. Zu diesem Zwecke wird in der Regel eine Nebenfeder zwischen Gangregler und Antriebskraft (Hauptfeder) eingeschaltet, welche in regelmäßigen Zwischenräumen nachgespannt wird.Clock with main and secondary spring devices that are suitable 'the in-soot of an uneven driving force, e.g. B. a spring or possibly also a motor to reduce to the regulator of a drive are known. For this purpose, there is usually a secondary spring between the regulator and the drive force (Main spring) switched on, which is re-tensioned at regular intervals.

Bei derartigen Einrichtungen besteht der Nachteil, da.ß beim Ablaufen der Hauptfeder bzw. bei Stillstand des Motors auch die Nebenfeder von. ihrer normalen Spannung auf Null heruntergeht. Die vorliegende Erfindung hat den Zweck, diesen Nachbeil, zu beseitigen. Dies geschieht dadurch, daß selbsttätig eine Sperrung in Wirksamkeit tritt, welche die Entspannung der Nebenfeder verhindert, so- daß die Nebenfeder stets ihre normale Spannung beibehält, selbst wenn die Hauptfeder ganz abgelaufen sein sollte.With such devices there is the disadvantage that when running the main spring or, when the engine is at a standstill, also the secondary spring of. their normal Voltage goes down to zero. The present invention aims to achieve this After-ax to eliminate. This is done by automatically locking in Effectiveness occurs, which prevents the relaxation of the secondary spring, so that the Subspring always maintains its normal tension, even when the mainspring is full should have expired.

Eine derartige Einrichtung ist in der beiliegenden Zeichnung schematisch dargestellt. Sie arbeitet in der Weise, daß, wenn der Hebel h, durch den die nicht gezeichnete Nebenfeder auf gleicher Höbe ihrer Spannung gehalten wird, durch den Auslösebetrieb i freigegeben wird, zugleich der Spierrhebel z gehoben wird. Dies geschieht dadurch, daß mit dem Hebel k die Scheibe i fest verbunden ist, welche den Stift z trägt. Kann der Hebel h infolge Nachlassens der Antriebskraft (Hauptfeder) nicht mehr gedreht werden, so wird deT Auslösetrieb i und mithin das Steigrad k durch. die Sperrklinke 3 des Hebels z gesperrt und infolgedessen eine Entspannung der Nebenfeder verhindert.Such a device is shown schematically in the accompanying drawing shown. It works in such a way that when the lever h, through which it is not Drawn secondary spring is kept at the same level of their tension by the Trigger mode i is released, at the same time the spier lever z is lifted. this happens in that the disk i is firmly connected to the lever k, which carries the pen z. Can the lever h due to a decrease in the driving force (main spring) are no longer rotated, then deT tripping mechanism i and consequently the climbing gear k by. the pawl 3 of the lever z locked and consequently a relaxation the secondary spring prevents.
