Description

Hölzerner Luftschraubenflügel Gegenstand des Hauptpatents ist eine hölzerne Luftschraube mit mutgenietetem. aufgeschraubtem bz«-. mutgenageltem Blechstreifen als Kantenschutz, deren Kennzeichen darin besteht, daß der Blechstreifen mit einem aufgelöteten, die Köpfe der Befestigungsmittel abdeckenden Schutzblech ver sehen ist.Wooden propeller wing The subject of the main patent is one wooden propeller with mutually riveted. screwed on bz «-. mutnageltem sheet metal strip as edge protection, the characteristic of which is that the sheet metal strip with a Soldered, the heads of the fasteners covering mudguard see ver is.

plan hat gefunden, daß sich die Bauart wesentlich vereinfachen IM wenn man zum Tranen des Kastenschutzbleches lediglich zwei schmale Blechstreifen benutzt, die je auf beiden Seiten der Schraubenkante in Längsrichtung des Schraubenblattes verlaufen Durch die Vervollkommnung wird eilt groll flächiges Beschlagblech entbehrlich, uns zu einer Verkleinerung der heim Betrieb d .i. Schraube entstehenden Fliehkräfte führt. Außerdem wird (las Aufbringen des Oberbleches erleichtert. das in bequemer Weise fest auf die Profilnase gelegt und mit den tnterblechstreifen dicht verlötet «-erden kann. Bei Überholungen oder Erneuerungen braucht man nur das Oberblech von den schmalen Unterblechstreifen abzulöten.plan has found that the design can be significantly simplified IM if you only have two narrow metal strips to tear the box fender used, each on both sides of the screw edge in the longitudinal direction of the screw blade run Due to the perfection, groll flat fitting sheet is quickly dispensable, us to downsize the home operation d .i. Centrifugal forces generated by the screw leads. In addition, the application of the top sheet is facilitated. This is more convenient Lay it firmly on the profile nose and solder it tightly to the metal sheet strips «-Can earth. For overhauls or renewals, you only need the top sheet of unsolder the narrow underbody strip.

Die Zeichnung zeigt eile Ausführungsbeispiel der Erfindung in Abb. 1 in Draufsicht auf ein Bruchstück eines Schraubenblattes und in Abb. a im Querschnitt durch das Schraubenblatt.The drawing shows an exemplary embodiment of the invention in Fig. 1 in plan view of a fragment of a screw blade and in Fig. A in cross section through the screw blade.

Es bezeichnet a den hölzernen Schraubenflügel, b1 Tragbleche, c die diese Bleche mit dem Flügelkörper verbindenden Niete, e das auf die Tragbleche aufgelötete Schutzblech, das die Kipfe der Befestigungsmittel c abdeckt, und f die Drahtgazeummantelung mit der Einbettung in den Klebstoff g. Zum Tragen des Oberbleches e dienen erfindungsgemäß lediglich die beiden schmalen Unterlagesti-eifen b1, von denen sich je eines auf der Blattunter- und -oberseite in der Nähe It denotes a the wooden screw wing, b1 supporting plates, c the rivets connecting these plates to the wing body, e the protective plate soldered onto the supporting plates, which covers the tips of the fasteners c, and f the wire gauze sheathing with the embedding in the adhesive g. According to the invention, only the two narrow support strips b1 are used to support the upper plate e, one of which is located on the lower and upper side of the sheet in the vicinity
