PATENTAMTPATENT OFFICE
Die Broncepulver- undBrocatfarbenfabrikation erfolgt bekanntlich ganz allgemein in der Weise, dafs man die für den gedachten Zweck als geeignet erkannten Legirungen zwischen Dampfhämmern oder anderweit in der sogenannten Schaumgoldfabrikation zu feinsten Häutchen ausschlägt und die dünnen Metallfolien oder die Schawine durch Kratzbürsten und Reibmaschinen unter Zusatz von Fett iein zerkleinert. As is well known, the manufacture of bronze powder and brocat paint is generally carried out in the manner that the alloys between steam hammers recognized as suitable for the intended purpose are to be found or otherwise in the so-called foam gold production turns into the finest skins and the thin metal foils or the pork is crushed by scraping brushes and grating machines with the addition of fat.
Man hat sich seit langem vergeblich bemüht, diese ungemein langwierige und mühsame Fabrikation durch directe Herstellung der Broncepulver vom Metallblock aus ohne den Umweg der Herstellung von Metallfolien zu ersetzen.One has tried in vain for a long time, this extremely tedious and arduous Manufacture by direct production of the bronze powder from the metal block without the Detour to replace the production of metal foils.
Es ist nunmehr gelungen , Legirungen herzustellen , welche mit einer gewissen Sprödigkeit zugleich die für den eigenen Glanz der Bronceflitter in feinster Verreibung erforderliche Dehnbarkeit besitzen und welche ohne Schwierigkeiten vom Metallblock aus unter Umgehung der Metallschlägerei die Herstellung der feinsten Broncefarben ermöglichen.We have now succeeded in producing alloys with a certain brittleness at the same time the finest trituration required for the bronze tinsel to shine Have ductility and which can be produced without difficulty from the metal block, bypassing the metal brawl the finest bronze colors.
Die für diesen Zweck erprobten Legirungen sind Legirungen von Kupfer, Aluminium und Wismuth. Der Aluminiumgehalt kann variiren zwischen 5 und 10 pCt., der Wismuthgehalt von 0,05 bis 0,1 pCt. Bei einem höheren Gehalt an Wismuth wird die Legirung zu hart, zu spröde und läfst sich überhaupt nicht mehr in eine Metallfarbe verwandeln; das Pulver bleibt körnig und stumpf.The alloys tried out for this purpose are alloys of copper, aluminum and Bismuth. The aluminum content can vary between 5 and 10 pct., The bismuth content from 0.05 to 0.1 pCt. With a higher content of bismuth the alloy becomes too hard, too brittle and cannot be transformed into a metallic color at all; the powder remains grainy and dull.
Um zu verschiedenen Nuancen zu gelangen, verwendet man den variirenden Aluminiumzusatz, und nehmen die so bereiteten Legirungen bei geeigneter Temperatur auch Anlauffarben an , die durch Erhitzen der Pulver unter Luftzutritt erzeugt werden. Die angegebenen Legirungen haben vor den gewöhnlichen Broncepulvern noch den besonderen Vorzug der weit gröfseren Beständigkeit gegen oxydirende Einflüsse und sind daher haltbarer als die gewöhnlichen Broncen.To get to different nuances, one uses the varying aluminum additive, and at a suitable temperature the alloys thus prepared also tarnish generated by heating the powder in the presence of air. The specified Alloys have the special advantage over the usual bronze powders of being far more resistant to oxidizing influences and are therefore more durable than the ordinary bronzes.
Die mechanische Bearbeitung des Metalles ist folgende: Die Metallstangen werden in Fräsmaschinen gefräst, die Späne geglüht und unter Pochhämmern fein gepocht, nochmals geglüht, auf der Reibmaschine gemahlen, dann gewaschen, getrocknet, gesiebt und zwischen Walzen polirt.The mechanical processing of the metal is as follows: The metal bars are in Milling machines milled, the chips annealed and finely pounded under pounding hammers, again annealed, ground on the grater, then washed, dried, sifted and between Rolls polished.
