Patentiert im Deutschen Reiche vom 14. Juni 1913 ab.Patented in the German Empire on June 14, 1913.
Hohle Ketten, wie sie namentlich in der Schmuckwarenindustrie verwendet werden, wurden bis jetzt hergestellt durch Verarbeitung von Metallröhren mit offener Längsnaht, in die zur Verstärkung und zur Vermeidung des Brechens und Zerdrückens beim Biegen der Röhren Draht aus Kupfer oder Eisen eingezogen wurde, der nach Fertigstellung der Ketten durch Behandlung mit Säuren wiederHollow chains, such as those used in the jewelry industry by name, were made produced up to now by processing metal tubes with an open longitudinal seam, in those to reinforce and to avoid breaking and crushing when bending the Tubes of wire made of copper or iron were drawn in after the completion of the Chains by treatment with acids again
ίο entfernt wurde. Diese Herstellungsart lieferte von Hand gelötete hohle Ketten aus der Längsrichtung nach offenem Röhrendraht.ίο has been removed. This production method delivered hand-soldered hollow chains from the longitudinal direction to open tubular wire.
Das vorliegende Verfahren beschreitet der herkömmlichen Herstellungsweise gegenüber neue Wege. Es werden zur Herstellung der hohlen Metallketten neuartige fugenlose Drähte mit einem besonders gearbeiteten Lotkern verwendet und dadurch ermöglicht, hohle Ketten aus fugenlosen Röhren rein maschinell herzustellen. Das Verfahren fußt auf dem unterschiedlichen Schmelzpunkt von echten oder unechten schwer- und leichtschmelzbaren Metallegierungen. The present process goes against the conventional production method new ways. New types of seamless wires are used to produce the hollow metal chains used with a specially crafted solder core and thus enables hollow chains Manufactured from jointless tubes purely by machine. The procedure is based on the different Melting point of real or fake metal alloys that are difficult to melt and easily melt.
Beispielsweise zur Herstellung goldener hohler Ketten wird zunächst ein Lotdraht folgender Beschaffenheit hergestellt:For example, for the production of golden hollow chains, a solder wire is first used as follows Made texture:
In einen festen Doppelmantel des zu Draht zu verarbeitenden und zu ziehenden Goldes wird zunächst eine Schicht sehr schwerflüssigen Goldlotes (Hartlotes) eingetragen; die dem Kernstück zugewandte Seite wird mit einer lotwidrigen Masse versehen und dann das Kernstück mit einer leichtflüssigen und leichtschmelzbaren Metallegierung ausgegossen. Der in dieser Weise hergestellte Metallzylinder mit Loteinlagen wird dann zu Draht von gewünschter Stärke ausgezogen und in bekannter Weise zu Ketten verarbeitet, wobei es sich empfiehlt, das zum Abschneiden des Drahtes verwendete Messer so zu profilieren, daß die entstehende Stoßfuge eine wenn auch kleine, kreisrunde Erweiterung zeigt. Der fertig eingehängte, noch ungelötete Kettenstrang kommt nun, die Fuge nach unten zeigend, auf eine der gebräuchlichen Lötmaschinen und wird hier zunächst so weit erhitzt, daß die unechte leichtschmelzende Legierung des Kernstückes schmilzt, aus den Stoßfugen heraustritt und abtropft. Der Kettenstrang wird dann einer gründlichen mechanischen und ehemischen Reinigung unterzogen, wobei noch anhaftende Spuren der unechten Kernlegierung entfernt werden, in Borax gut ausgekocht, noch- einmal auf die Lötmaschine gebracht, dort bis zum Schmelzpunkt des echten Hartlotes weiter erhitzt und nach einem der bekannten Verfahren fertig gelötet.In a solid double jacket of the gold to be processed and drawn into wire First, a layer of very viscous gold solder (hard solder) is applied; the dem The side facing the core is provided with a non-soldering compound and then the The core is poured out with a fluid and easily meltable metal alloy. Of the Metal cylinders made in this way with solder inlays are then turned into wire of desired Stripped starch and processed into chains in a known manner, whereby it is advisable to cut the Wire used to profile the knife so that the resulting butt joint an albeit shows small, circular extension. The already attached, unsoldered chain strand Now comes, with the joint pointing downwards, onto one of the common soldering machines and is first heated so far that the fake, easy-melting alloy of the core piece melts, emerges from the butt joints and drips off. The chain strand then undergoes a thorough mechanical and former Subjected to cleaning, with still adhering traces of the fake core alloy being removed, well boiled in borax, brought back to the soldering machine, there up to the melting point of the real hard solder heated further and soldered ready according to one of the known methods.
Das vorliegende Verfahren liefert also auf rein maschinellem Wege gelötete hohle Ketten, die gegenüber den bisher gebräuchlichen sich noch dadurch auszeichnen, daß die unschöne, auch praktisch störende offene Längsfuge der Röhre in Fortfall kommt; es bedeutet deshalb einen wesentlichen Fortschritt.The present process thus yields hollow chains soldered by a purely mechanical method, which are still characterized by the fact that the unsightly, practically annoying open longitudinal joint of the tube is also eliminated; it means therefore a significant advance.
