Description

Geschichtete Blattfeder. Zwischen die Blätter geschichteter Blattfedern hat man bereits Einlagen aus Papier, Fiber, Metall, gewebtem Stoff eingelegt, die mit einem Schmiermittel bestrichen sind und den Zweck haben, das Rosten zu verhindern, damit die Federblätter leicht aufeinandergleiten. können. Diese Wirkung wird beeinträchtigt, wenn. Flüssigkeit oder Feuchtigkeit zwischen die Blätter gelangt, weil dann die Einlagen zerstört werden oder feuchte Stellen auf den Blättern gebildet werden, wodurch Rost entsteht, dessen Bildung gerade vermieden werden soll. Urrihüllungen für geschichtete Blattfedern zum Schutz gegen Eindringen von Staub sind zwar auch bereits bekannt. Sie bestehen aus Metallmänteln, die die Feder überkappen. Weil sie aber die nicht unerheblichen Durchbiegungen der Feder mitmachen müssen, sind sie schwer zu dichten. Außerdem schützen sie nicht gegen das Eindringen von Feuchtigkeit.Layered leaf spring. Leaf springs layered between the leaves if you have already inserted inlays made of paper, fiber, metal, woven fabric, the are coated with a lubricant and have the purpose of preventing rusting, so that the spring leaves slide easily on each other. can. This effect is impaired if. Liquid or moisture gets between the leaves because then the Deposits are destroyed or damp places on formed by the leaves causing rust, the formation of which is just to be avoided. Original wrappings for layered leaf springs to protect against ingress of dust are also already known. They consist of metal sheaths that cover the spring. because But they have to take part in the not inconsiderable deflections of the spring they are difficult to compose. In addition, they do not protect against the ingress of moisture.

Nach. der Erfindung werden Einlagen gleicher Art zwischen die Blätter der geschichteten Feder eingelegt, die mit Bändern, z. B. aus Leder, Eisengarn-, Baumwollgarnbändern und ähnlichen Bändern, umwickelt sind. Umwicklungen dieser Art sind durchaus Staub-und wasserdicht. Es ist vorteilhaft, das Glättungsmittell in einer sehr dünnen Schicht unmittelbar auf die Oberfläche der Federblätter aufzubringen. Es gibt Glättungsmittel, die soffort erstarren, z. B. Paraffinlösungen. Die Einlage wird darauf in trocknem Zustande eingelegt. Diese Maßnahme hat gegenüber den mit Glättungsmitteln bestrichenen Einlagen den Vorzug, daß das Glättungsmittel beim Biegen. der Einlage nicht abplatzt.To. of the invention are deposits of the same type between the sheets the layered spring inserted, which with ribbons, z. B. made of leather, iron thread, Cotton thread ribbons and similar ribbons, are wrapped. Wraps of this kind are absolutely dust and waterproof. It is advantageous to use the smoothing agent in apply a very thin layer directly to the surface of the spring leaves. There are smoothing agents that solidify instantly, e.g. B. paraffin solutions. The deposit is placed on it in a dry state. This measure has compared to the with Smoothing agents coated deposits have the advantage that the smoothing agent when To bend. the insert does not flake off.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Abb. i zeigt eine Seitenansicht der Feder ohne Umwicklung.An exemplary embodiment of the subject matter of the invention is shown in the drawing. Fig. I shows a side view of the spring without wrapping.

Abb. 2 zeigt die Feder in umwickeltem Zustande.Fig. 2 shows the spring wrapped around it.

Abb. ,3 zeigt einen Querschnitt. Die glatten Einlagen a, die zwischen je zwei Blätter eingelegt sind, sind in Paraffin eingebettet, das auf die Oberflächen der FederblÄtter aufgestrichen wird. Auf die Feder sind oben und unten an den Rändern umgebogene Pappblätter b gelegt. Um die ges chichtete Feder ist mindestem ein Lederc streifen gewickelt, der die Feder einhüllt. Die so entstandene Hülle wird wasserdicht imprägniert, um die Feder gegen Einwirkung von Mässe 'zu schützen. Statt Leder können auch Bänder aus Eisengarn, Baumwollgarn oder ;ähnlichen Stoffen benutzt werden.Fig. 3 shows a cross section. The smooth inlays a, which between Every two sheets are inserted, are embedded in paraffin, which is on the surfaces the spring leaves is spread. On the feather are top and bottom on the edges folded cardboard sheets b placed. There is at least one leather around the layered pen strip wrapped around the feather. The resulting cover becomes waterproof impregnated to protect the spring against the effects of measure. Instead of leather you can ribbons made of iron thread, cotton thread or similar materials can also be used.
