KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Eine der bis jetzt gebräuchlichen Methoden des Hartlöthens von Gegenständen beruht im Auflegen des mit Loth gemengten Borax auf oder neben die zu löthenden Stellen.One of the methods of brazing objects in use up to now is based in Place the borax mixed with solder on or next to the areas to be soldered.
Der Gegenstand wird in ein offenes Feuer gebracht und so lange erhitzt, bis das Löthmetall darauf schmilzt und sich auf oder in die Löthfugen ergiefst. Diese Methode eignet sich für Gegenstände, welche durch Abzundern oder event. Ueberhitzung keinen Nachtheil erleiden, ist aber besonders bei Fahrradbestandtheilen, für welche die Rohre ohnehin auf das Schwächste bemessen sind, und durch Beschaffenheit des Materials die geringste Ueberhitzung das Rohmaterial spröde und brüchig macht, nicht oder nur unvortheilhaft anwendbar. Ebenso bereitet das Entfernen jener harten Stellen, welche durch das Aufschmelzen von Borax verursacht werden, bedeutende Schwierigkeiten.The object is placed in an open fire and heated until the soldering metal then melts and pours out on or into the solder joints. This method is suitable for objects that are due to scaling or event. Overheating does not suffer any disadvantage, but is especially with bicycle parts, for which the pipes are anyway dimensioned to the weakest, and by nature The slightest overheating of the material makes the raw material brittle and fragile, cannot be used or can only be used unfavorably. Also prepares the removal of those hard spots, which were caused by the melting caused by borax present significant difficulties.
Auch das Eintauchen der zu löthenden Gegenstände in ein geschmolzenes Metallbad, wie es bei einem anderen bekannten Löthverfahren üblich ist, liifst an sich den angestrebten Zweck in keiner Weise erreichen und vermehrt durch ungleichmäfsiges und dennoch haltloses Anhaften des Lothes an den davon frei zu haltenden Stellen die eben erwähnten Schwierigkeiten in ganz besonderem Mafse.Also immersing the objects to be soldered in a molten metal bath, as is customary with another known soldering process, it is actually the desired one The purpose is in no way achieved and is increased by the uneven and yet unsteady clinging of the solder to the solder The above-mentioned difficulties, to a very special degree, have to be kept clear.
Das vorliegende Verfahren, welches alle diese benannten Schwierigkeiten behebt, besteht im Folgenden:The present method, which overcomes all of these noted difficulties, consists in The following:
Die mit einander zu verlöthenden Gegenstände, z. B. Rohre und Muffen bezw. Winkelstücke von Fahrrädern, werden in einander geschoben und wie gebräuchlich mit Stiften oder Drähten provisorisch mit einander verbunden. The objects to be soldered together, e.g. B. pipes and sleeves respectively. Elbows of bicycles, are pushed into each other and, as is customary, temporarily connected to each other with pins or wires.
Die zu verbindenden Theile werden im Ganzen oder blos mit ihren Löthstellen mit irgend einem Desoxydationsmittel überzogen, z. B. in eine Lösung von Borax oder Borsäure, in heifses Wasser getaucht, wodurch dieselbe in die Löthfugen eindringt.The parts to be connected are either wholly or simply with their soldering points coated with any deoxidizer, e.g. B. in a solution of borax or boric acid, immersed in hot water, which penetrates the solder joints.
In diesem Zustande wird der Gegenstand in geeigneter Weise, z. B. über einer Flamme, er- \värmt, wobei das Lösungsmittel, also das Wasser, verdunstet und das trockene Desoxydationsmittel, also Borax bezw. Borsäure, zurückbleibt. Es wird nun ferner dort, wo kein Loth anhaften soll, z.B. auf der Aufsenseite, der Borax, das Desoxydationsmittel, also der Borax- oder Borsäureüberzug (mit einer Bürste) entfernt; darauf werden die Flächen mit einer Schutzmasse, z. B. einem Gemenge von Graphit und Wasser, bestrichen, worauf man den Gegen- instand nach dem Trocknen in irgend ein Metallbad, welches die Löthung bewirken soll, eintaucht und so lange (ca. 15 bis 30 Sekunden) darin beläfst, bis sich die zu löthenden Gegenstände bis zur Rothglühhitze erwärmt haben:In this state, the object is suitably, e.g. B. over a flame, \ heated, whereby the solvent, i.e. the water, evaporates and the dry deoxidizer, so borax respectively. Boric acid, remains. It is now also there where no solder should adhere, e.g. on the outside, the borax, the deoxidizer, i.e. the borax or boric acid coating (with a brush) removed; then the surfaces are covered with a protective compound, e.g. B. a mixture of graphite and water, coated, whereupon the object after drying is placed in some metal bath, which should cause the soldering, immersed and so long (approx. 15 to 30 seconds) left in it until the objects to be soldered have warmed up to red glow heat:
Der Löthprocefs vollzieht sich in der Weise, dafs das Desoxydationsmittel (der Borax bezw. Borsäure) in den Fugen geschmolzen wird und das eintretende flüssige Metall zum Anhaften gelangt.The soldering process takes place in such a way that the deoxidizing agent (borax or Boric acid) is melted in the joints and the entering liquid metal to adhere got.
Das Metallbad kann sowohl aus reinem Metall, wie Kupfer (für Harlloth), Zinn (fürThe metal bath can be made of pure metal, such as copper (for Harlloth), tin (for
Weichloth) als auch aus Legirungen und Phosphormetall bestehen.Soft solder) as well as from alloys and phosphor metal exist.
