G. HECHELMANN in HAMBURG. Neuerung an Comparsrosen.G. HECHELMANN in HAMBURG. Innovation in Compars roses.
Patentirt im Deutschen Reiche vom 23. Februar 1883 ab.Patented in the German Empire on February 23, 1883.
Diese Neuerung an Compafsrosen bezweckt, das von Sir William Thomson zuerst angewendete Princip einer langen Schwingungsdauer bei geringerem Gewicht in anderer Weise zur Ausführung zu bringen, um eine Rose zu construiren, welche eine weniger subtile Behandlung erheischt und mit weniger Kosten herzustellen ist, als die von Thomson, da hauptsächlich der erste Punkt der Einführung bei der Handelsmarine hinderlich ist.This innovation in Compafsrosen aims at that first applied by Sir William Thomson Principle of a long period of oscillation with a lower weight in another way Execution to construct a rose, which is a less subtle treatment demanded and manufactured at a lower cost than Thomson's, since mainly the first point of introduction is a hindrance to the merchant navy.
UnterBeibehaltungder GlimmerkarteundMetallträger für die Nadeln, wie bei der gewöhnlichen Rose, wird das Hauptgewicht der Rose nach dem Rande und tiefer unter die Karte gelegt. Durch die so erhaltene grofse Schwingungsdauer von 15 Secunde-n und des ca. 16 mm unterm Aufhängepunkt liegenden Schwerpunktes bekommt die Rose einen hohen Grad von Ruhe und Stabilität gegen Erschütterungen, ohne dafs ihrer exacten EinstellungsfähigkeitEintrag gethan wird.Retaining the mica card and metal support for the needles, as with the ordinary one Rose, the main weight of the rose is placed after the edge and deeper under the card. By the thus obtained long period of oscillation of 15 seconds and approx. 16 mm below the point of suspension With the center of gravity lying down, the rose acquires a high degree of calm and stability against vibrations, without it exact employability entry is made.
Durch diese Anordnung der Nadeln wird, wie darauf bezügliche Versuche ergeben haben, selbst bei grofser Annäherung der Compensationsmagnete eine exacte Uebereinstimmung der Deviation mit der nach der bekannten Formel berechneten erzielt. Ebenso findet bei Anwendung von Correcturen zur Beseitigung der quadrantalen Deviation nur eine unwesentliche Induction durch die Rose statt.This arrangement of the needles, as related tests have shown, even when the compensation magnets come very close, there is an exact correspondence of the Deviation achieved with that calculated according to the known formula. Also applies to of corrections to remove the quadrant deviation, only an insignificant induction held by the rose.
Eine Rose nach dieser Construction ist in Fig. ι als Ansicht von unten, in Fig. 2 und 3 von der Seite dargestellt. Die 16 kurzen, flachen Nadeln η sind unter sich parallel, je zwei unter einander senkrecht zur Karte k durch Winkelstücke a, Ring b, Steg c mit der Karte und dem Hütchen d verbunden. Die Nadeln sind mit ihren Enden, welche dem betreffenden Pol entsprechen, möglichst an den Rand der Karte gelegt und schliefsen je vier Paar mit der Nord-Südrichtung derselben einen Winkel von 15 bezw. 450 ein. ,A rose according to this construction is shown in Fig. Ι as a view from below, in Fig. 2 and 3 from the side. The 16 short, flat needles η are parallel to each other, two each perpendicular to the card k by angle pieces a, ring b, bar c connected to the card and the hat d . The ends of the needles, which correspond to the pole in question, are placed as close as possible to the edge of the card and each four pairs close with the north-south direction of the same at an angle of 15 or respectively. 45 0 a. ,
