KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung besteht darin, Pendeluhren mit mehreren gegenseitig sich corrigirenden Pendeln zu versehen.The present invention consists in pendulum clocks with several mutually exclusive to provide corrective pendulums.
In der beiliegenden Zeichnung ist eine mit vorliegender Neuerung ausgestattete Uhr in zwei Figuren dargestellt.In the accompanying drawing, a watch equipped with the present innovation is shown in two figures shown.
Auf der hinteren Platine des Uhrwerkes werden drei Pendel D aufgehängt. Diese sind mit dem Werk durch die Gabel C und den Anker A verbunden, der in das Steigrad eingreift. Jedes Pendel kann für sich nach irgend einer gebräuchlichen Pendelconstruction hergestellt werden; so kann das mittlere eine Pendelstange aus gefirnifstem Tannenholz erhalten, während das eine Seitenpendel ein Stangen-Compensationspendel und das andere ein Quecksilber-Compensationspendel ist. Alle drei Pendel sind dqrch eine Kuppelungsstange K mit einander verbunden, jedoch steht immer nur ein Pendel, beispielsweise das mittere, mit dem Antriebsmechanismus der Uhr in Verbindung. Wenn es indessen nöthig erscheint, kann auch für jedes Pendel ein besonderes Uhrwerk angeordnet werden. An Stelle einer einzelnen Kuppelungsstange K können auch zwei von einander unabhängige Stangen verwendet werden. Three pendulums D are hung on the rear plate of the clockwork. These are connected to the work through the fork C and the anchor A , which engages in the steering wheel. Each pendulum can be made by itself according to any conventional pendulum construction; so the middle one can receive a pendulum rod made of varnished fir wood, while one side pendulum is a rod compensation pendulum and the other a mercury compensation pendulum. All three pendulums are connected to one another by a coupling rod K , but only one pendulum, for example the central one, is connected to the clock's drive mechanism. If, however, it seems necessary, a special clock mechanism can be arranged for each pendulum. Instead of a single coupling rod K , two rods that are independent of one another can also be used.
Das Uhrwerk selbst kann Feder- oder Gewichtsaufzug haben. Es kann ferner die Einrichtung getroffen werden, dafs, im Falle drei Werke zur Verwendung gelangen, alle von einer Welle aus aufzuziehen sind.The movement itself can be spring or weight wound. It can also be the establishment it can be made that, in the case of three works, they are all to be drawn up from one shaft.
Die Anordnung dreier Pendel gegenüber einem einzigen Pendel hat zahlreiche Vorzüge. Namentlich wird eine gröfsere Gleichmäfsigkeit im Gange erzielt, die durch ein einziges Pendel, auch wenn es ein Compensationspendel ist, nicht erreicht werden kann. Dafs ein einziges, nach bisheriger Construction hergestelltes Compensationspendel keinen ganz gleichmäfsigen Gang haben kann, rührt hauptsächlich daher, dafs bei Metallstangen-Compensationspendeln die Ausdehnung — der einzelnen Metalle — bei verschiedenen Temperaturintervallen nicht ganz gleich ist, was auch bei den Glasgefäfsen der Quecksilber - Compensationspendel der Fall ist.The arrangement of three pendulums over a single pendulum has numerous advantages. In particular, a greater uniformity is achieved in the swing, which is achieved by a single pendulum, even if it is a compensation pendulum, it cannot be reached. That a single Compensation pendulum manufactured according to previous construction not a completely uniform one Can go, is mainly due to the fact that in the case of metal rod compensation pendulums the expansion - of the individual metals - not at different temperature intervals It does not matter what the mercury compensation pendulum of the glass vessels Case is.
