KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die alten bekannten Versilberungsverfahren durch Eintauchen oder Anreiben sollten eine wesentliche Verbesserung durch das Verfahren nach der deutschen Patentschrift 118922 erfahren, wenn dem Versilberungsgemisch chlorabgebende Substanzen, wie Eisenchlorid, Kupferchlorid, Zinnchlorid, hinzugefügt werden, um, eventuell durch Lichtwirkung, zu Silberchlorür reduziertes Silberchlorid zu regenerieren und dadurch eine größere Löslichkeit desselben in den hinzugegebenen Chloralkalien zu erzielen.The old well-known silver plating processes by dipping or rubbing should be a experienced significant improvement through the process according to German patent specification 118922, if chlorine-releasing substances such as ferric chloride, copper chloride, Tin chloride, can be added to make silver chloride, possibly through the action of light to regenerate reduced silver chloride and thereby a greater solubility of the same in to achieve the added chlorine-alkalis.
Die Patentschrift 122908 desselben ErfindersThe same inventor's patent specification 122908
ersetzt das Lösungsmittel des Chlorsilbers, die Chloralkalien,. ganz odef teilweise durch Halogenverbindungen der Erdalkalimetalle und erzielt dadurch eine vermeintliche erhöhte versilbernde Wirkung.replaces the solvent of the chlorine silver, the chlorine-alkalis. entirely or partially by halogen compounds of the alkaline earth metals and thereby achieves an alleged increased silvering Effect.
Die Patentschrift 173912 weist jedoch darauf hin, daß durch alle diese Versilberungsverfahren kein reiner Silberglanz erzielt wird, derselbe auch zum Teil die chemischen Eigenschaften des reinen Silbers verliert, und schlägt zur Reduktion des Chlorsilbers Natriumhyposulfit unter Zusatz vou Salmiakgeist vor.However, patent 173912 points to this point out that none of these silver plating processes achieve a pure silver shine, it also partly loses the chemical properties of pure silver, and strikes to reduce the silver chlorine sodium hyposulfite with the addition of salmiakgeist.
Die Patentschrift 189879 gibt endlich eine Masse zur Anreibungsversilberung und Verzinnung und zum Putzen von Weißmetall an, in welcher neben Chlorsilber und dessen bekannten Lösungsmitteln (Kochsalz, Salmiak) im wesentlichen nur noch Zink und Zinnchlorür zugegen sind. Dieses Versilberungsbzw. Versilberungsverzinnungsverfahren ist aber, wie der Erfinder ausdrücklich erwähnt, nur auf Weißmetall anwendbar.The patent specification 189879 finally gives a mass for grinding silver plating and tinning and for cleaning white metal, in which in addition to chlorine silver and its well-known Solvents (table salt, salmiak) essentially only zinc and tin chloride are present. This silvering or. However, the silver plating process is as the inventor expressly mentions, only applicable to white metal.
Dagegen werden nach dem vorliegenden Verfahren Silberüberzüge auf Zugabe von Antimon- oder Wismutsalzen auf Metallen, im besonderen Kupfer oder Metallegierungen, besonders Messing, dadurch erzeugt, daß man sich in der bekannten Weise eine Mischung dieses Silbersalzes mit oder ohne Chloralkalien und mit organischen Säuren bzw. organischen sauren Salzen herstellt, der man das Nichtsilbersalz, wie z. B. Antimon- oder Wismutsalz, und für das Anreibeverfahren etwas Putzmaterial, wie Zinnasche usw., beifügt. Als Nichtsilbersalze kommen in erster Linie in Betracht die organischen Salze, dann die Sulfate, ferner die Chloride, Nitrate des Antimons, Wismuts. Durch Anreiben dieser angefeuchteten Mischung auf Metallen, wie Kupfer usw., bzw. Metallegierungen, wie Messing usw., bzw. durch Eintauchen der vorerwähnten Metalle oder Metallegierungen in die wässerige, teilweise Lösung der angeführten Salze entstehen dann stark und schön glänzende Überzüge (Silberüberzüge). Diese Überzüge sind meist indifferent gegen mäßige Temperaturerhöhung oder auch gegen atmosphärische Einflüsse und unterscheiden sich von den bekannten gewöhnlichen Silberüberzügen schon äußerlich durch ihre veränderte Farbe bzw. durch ihren stark und schön spiegelnden Hochglanz. Die im Glanz stärksten, schönsten und dauerhaftesten Überzüge wurden durch den Gebrauch des Kaliumantimonyltartrats und des Wismuttartrats erzielt.In contrast, according to the present process, silver coatings are based on the addition of antimony or bismuth salts on metals, especially copper or metal alloys, especially Brass, produced by mixing in the known manner this silver salt with or without chloralcohols and with organic acids or organic acidic salts, which one uses the non-silver salt, such as. B. antimony or bismuth salt, and add some cleaning material, such as tin ash, etc., for the rubbing process. as Non-silver salts are primarily the organic salts, then the sulfates, also the chlorides, nitrates of antimony, and bismuth. By rubbing this moistened Mixing on metals such as copper etc. or metal alloys such as brass etc., or by immersing the aforementioned metals or metal alloys in the aqueous, Partial dissolution of the salts mentioned then results in strong and beautifully shiny coatings (Silver coatings). These coatings are mostly indifferent to moderate increases in temperature or against atmospheric influences and differ from the known Ordinary silver coatings already outwardly through their changed color or through their strong and beautiful reflective high gloss. The strongest, most beautiful and most durable coatings were made through the use of potassium antimonyl tartrate and Bismuth tartrates scored.

1.25 g tartaric acid,
1.25 g chlorine silver, 2.50 g ^ ismutumtartaricum, 25.00 g water.
Die zu verwendenden Bleche müssen vorher sorgfältig gereinigt sein. Es ist geradezu auffallend, wie sehr die Versilberung durch den Antimon- bzw. Wismutzusatz verbessert wird. Die Silberschicht hat meist ohne jede weitere Politur den schönsten Spiegelglanz. Bei dem Antimon vor allem wurde das Ergebnis in einer Reihe unabhängiger Versuche immer wieder bestätigt.The sheets to be used must be carefully cleaned beforehand. It is downright striking how much the silver plating is improved by the addition of antimony or bismuth. The silver layer has mostly without any further Polish the most beautiful mirror finish. In the case of antimony in particular, the result was in repeatedly confirmed in a series of independent experiments.
