Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Zweiseitig offene Drahtflachfedern konnten bisher nur mit größter Vorsicht fabriziert werden; um sie wirklich auf beiden Seiten gleichmäßig auszubilden. Denn es muß unbedingt bei offenen Drahtflachfedern Wert darauf gelegt werden, daß die gebildeten Glieder beiderseits völlig übereinstimmen. Dies ist nun nach dem neuen Verfahren erreicht, indem zunächst Schraubenfedern flach gewalzt undFlat wire springs open on both sides could only be fabricated with great care up to now ; to make them really even on both sides. Because with open flat wire springs it is essential that the links formed completely match on both sides. This is now achieved according to the new method by first rolling helical springs flat and

ίο dann die einzelnen Gänge nach einer Seite unter Ausübung eines geringen Zuges nacheinander umgelegt werden.ίο then the individual courses to one side be knocked down one after the other while exercising a small pull.

In der Zeichnung ist eine nach dem neuen Verfahren hergestellte offene Drahtflachfeder dargestellt, und zwar zeigt Fig. 1 eine Vorder-, während Fig. 2 die Seitenansicht wiedergibt.In the drawing is an open flat wire spring produced by the new process shown, namely Fig. 1 shows a front, while Fig. 2 shows the side view.

Von einer einfachen Schraubenfeder α, welche in üblicher Weise flach gewalzt ist, werden die einzelnen Gänge b nach einer Seite nacheinander umgelegt, wobei ein geringer Zug auszuüben ist. Hierdurch entstehen Schlaufen c, welche völlig rechts und links übereinstimmen und zueinander, wie Fig. 2 erkennen läßt, dachziegelförmig zu liegen kommen.By a simple helical spring α, which is rolled flat in the usual way, the individual courses b are turned over to one side one after the other, with a slight pull to be exerted. This creates loops c, which completely coincide on the right and left and, as shown in FIG. 2, come to lie in the shape of a roof tile.

Das Umlegen der einzelnen Gänge kann in einfachster Weise durch ein zangenartiges Werkzeug erfolgen, welches sowohl durch Hand als auch maschinell den Drahtsch rauben gang umlegt. Hierbei muß das Werkzeug aber, wie schon vorgesagt, einen geringen Zug ausüben.The shifting of the individual gears can be done in the simplest way with a pliers-like tool take place, which turns the wire screw gear both by hand and by machine. Here, however, as already mentioned, the tool must exert a slight pull.

Je nach Ausübung des Zuges werden nun die einzelnen Schlaufen c weiter oder näher voneinander zu liegen kommen, was belanglos für den Erfindungsgedanken ist.Depending on how the pull is exercised, the individual loops c are now wider or closer come to lie from each other, which is irrelevant for the inventive idea.

Es wäre möglich, in gleicher Weise auch zwei oder mehr Drähte zu einer Schraubenfeder zu verwenden, um sie nach dem neuen Verfahren weiter zu bearbeiten.It would also be possible to use two or more wires to form a helical spring in the same way to be used to process them further using the new procedure.

Die Feder, welche an sich bekannt sein dürfte, jedoch aber nur durch umständliche Maschinen fertiggestellt werden mußte, hat die gleiche Elastizität und Widerstandsfähigkeit wie die nach den bekannten Herstellungsverfahren. The feather, which should be known per se, but only through cumbersome Machines had to be completed has the same elasticity and resistance like those according to the known manufacturing process.
