KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Das Verfahren bezweckt die Herstellung einer federnden Klammer, deren beide Schenkel eine vollständig gleiche Stärke und Spannkraft haben, was für die tadellose Erreichung des beabsichtigten Zweckes das erste Erfordernifs ist. Der Zweck, welchem die aus Gold gearbeitete Feder dienen soll, ist ein sicherer Verschlufs an goldenen Schmucksachen. Bei der geringen Gröfse einerseits und bei der Kostbarkeit des Materials andererseits kann die Sicherheit des Verschlusses nicht durch eine Steigerung der Gröfse der Spannschenkel erzielt werden, sondern es kann bei der gegebenen Menge Gold die höchste Spannkraft, also auch die gröfste Sicherheit des Verschlusses nur erreicht werden, wenn beide Schenkel durchaus gleich sind, denn die Spannkraft der ganzen Feder würde nicht gröfser als die Spannkraft des schwächeren Schenkels sein. Die Herstellung gleicher Schenkel hat man durch Umbiegen aus einem Stück, ferner durch Zusammenschweifsen oder Zusammenlöthen zweier gleichen Theile versucht, ohne das Ziel zu erreichen.The purpose of the method is to produce a resilient clip, the two legs of which are one have completely equal strength and resilience, which is essential for the impeccable achievement of the intended purpose is the first requirement. The purpose for which the gold wrought Feather is intended to serve as a secure lock on golden jewelry. With the small size on the one hand and with the On the other hand, the security of the lock cannot be compromised by a preciousness of the material Increasing the size of the clamping leg can be achieved, but it can be given at the given Amount of gold has the highest elasticity, thus also the greatest security of the closure can only be achieved if both legs are absolutely equal, because the elasticity of the whole spring would not be greater than the elasticity of the weaker leg. The production of the same legs is done by bending over from one piece, furthermore by Attempted to twist or solder together two equal parts without the aim to reach. Bei vorliegendem Verfahren werden die beiden vollkommen gleichen Metallstreifen a, Fig. ι bis 3 , mit einem zwischengelegten schmalen Metallstreifen b zusammengeschweifst, stark flach gehämmert und dann zwischen Walzen federhart gerollt. Hierbei erleiden die beiden Schenkel α keinerlei Aenderung ihrer Stärke, da sowohl das Schweifsen als auch das darauf folgende Zusammenpressen ganz auf Kosten des zwischengelegten dritten Stückes geschieht, und legen sich vollkommen flach auf einander, wie Fig. 4 zeigt, während aus einem Stück gespaltene oder aus nur zwei Streifen zusammengeschweifste das Bestreben zeigen, sich wie in Fig. 5 schnabelförmig zu verziehen. Sobald die Streifen federhart gewalzt sind, werden 'sie durch die Schnitte c in einzelne. Federn zertheilt.In the present method, the two completely identical metal strips a, FIGS. 1 to 3, are twisted together with an interposed narrow metal strip b , hammered very flat and then rolled between rollers as hard as a spring. Here, the two legs α suffer no change in their strength, since both the welding and the subsequent pressing is done entirely at the expense of the interposed third piece, and lie completely flat on each other, as shown in FIG from only two strips twisted together show the tendency to warp like a beak like in FIG. 5. As soon as the strips have been rolled as hard as a spring, the cuts c separate them. Divided feathers. Patent-Ansρrüch:Patent claim: Verfahren zur Herstellung einer federnden Klammer aus Edelmetall, gekennzeichnet durch das Zusammenschweifsen zweier vollkommen gleichen, die Schenkel der Klammer bildenden Metallstreifen (α) mit einem zwischengelegten Streifen (b) und darauf folgendem Flachhämmern und Hartwalzen des Werkstückes, zum Zweck, vollkommen anliegende Schenkel mit gleicher Spannung zu erzielen.Process for the production of a resilient clip made of precious metal, characterized by the welding together of two completely identical metal strips (α) forming the legs of the clip with an interposed strip (b) and subsequent flat hammering and hard rolling of the workpiece for the purpose of perfectly fitting legs with the same To achieve tension.
