Description

Schalltrichter aus plastischer Masse für Sprechapparate und Verfahren zur Herstellung desselben. - Die Erfindung betrifft einen Schalltrichter aus plastischer Masse für Sprechapparate und ein Verfahren zur Herstellung desselben.Plastic trumpets for speech apparatus and methods of manufacturing the same. - The invention relates to a horn made of plastic material for speech apparatus and a method for producing the same.

Der Zweck der Erfindung besteht im wesentlichen darin, einen Schalltrichter zu schaffen, welcher aus einer Masse besteht, die nach besonderer Behandlung leicht zum Vibrieren gelangt und sich daher für die Resonanzwirkung gut eignet. Außerdem i,#t ein derartiger Schalltrichter einfach, ?lauerhaft und billig herstellbar.The purpose of the invention is essentially to provide a bell to create, which consists of a mass that is light after special treatment comes to vibrate and is therefore well suited for the resonance effect. aside from that Such a trumpet is easy, difficult to manufacture and cheap to manufacture.

Die Erfindung besteht im wesentlichen darin, daß die Masse aus pulverisiertem Holz, Stärke und KGlophonium besteht. Das Mischungsverhältnis gestaltet sich hierbei etwa wie folgt: pulverisiertes Holz ioo Pfund, Stärke 4 523 - Kolophonium 33 - Bei der Ztisammensetzung dieser Mischung werden 2- Pfund Stärke mit 1 1 Wasser vermischt. Die Mischung von pulverisiertem Holz, Stärke und Kolophonium *wird auf einem Tisch ausgebreitet und das Stärkewasser alsdann auf die Mischungsschicht aufgesprengt, nim hierbei einen Teig zu bilden. Das Ganze wird hierauf gründlich durchgemischt, um in der Mischung die richtige Gleichmäßigkeit zu erzielen. Die Mischung wird alsdann auf etwa 2 Stunden sich selbst überlassen, worauf sie in eine Form geschüttet und unter einer Temperatur von etwa 45' C während 2o Minuten geröstet wird. Es ergibt sich hierbei als Resultat ein äußerst leichtes, sich kräuselndes Produkt, welches somit unter Aufwendung geringer Kosten herstellbar ist und erhebliche Resonanzwirkungen aufweist, so daß es sich für Schalltrichter besonders gut eignet.The invention consists essentially in the fact that the mass consists of pulverized wood, starch and KGlophonium. The mixing ratio is roughly as follows: pulverized wood ioo pounds, Thickness 4 523 - Rosin 33 - 2- pounds starch with 1 1 of water are mixed in the Ztisammensetzung this mixture. The mixture of pulverized wood, starch and rosin * is spread out on a table and the starch water is then sprinkled onto the layer of mixture, without forming a dough. The whole thing is then mixed thoroughly in order to achieve the right uniformity in the mixture. The mixture is then left to stand for about 2 hours, after which it is poured into a mold and roasted at a temperature of about 45 ° C. for 20 minutes. The result here is an extremely light, curling product, which can thus be produced at low cost and has considerable resonance effects, so that it is particularly well suited for horns.
