KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist eine Schiffsschraube, die in bekannter Weise aus einzelnen, hintereinanderliegenden Blättern oder Lamellen besteht, von denen jede mit einer Nabe versehen ist. Von den bekannten Schrauben dieser Art, bei denen die Blätter so hintereinander angeordnet sind, daß sie zusammen eine völlig glatte Fläche bilden, unterscheidet sich die Schraube nach vorliegender Erfindung dadurch, daß die einzelnen, hintereinanderliegenden Blätter gegeneinander versetzt sind, so daß sie einander teilweise überlappen, wobei durch die entsprechende Größenbemessung der Überlappung die gewünschte Steigung der Schraubenfläche und Flügel herbeigeführt wird. Diese Steigung kann beim Aufbau der Schraube unter Verwendung derselben Lamellenform an manchen Stellen der Schraube verändert, vergrößert oder verkleinert werden, je nachdem man die einzelnen Blätter oder Lamellen mehr oder weniger überlappen läßt, so daß aus einer Normallamelle Schrauben mit verschiedenen Steigungen aufgebaut werden können.The present invention is a ship's propeller, which in a known manner from consists of individual, one behind the other leaves or lamellae, each with a hub is provided. From the known screws of this type, in which the leaves are arranged one behind the other so that they together form a completely smooth surface, the screw according to the present invention differs in that the individual, consecutive sheets are offset from one another, so that they are partially one another overlap, whereby the desired overlap is determined by the appropriate dimensioning of the size Incline of the helical surface and wing is brought about. This slope can be used on some when building the screw using the same lamellar shape Set the screw can be changed, enlarged or reduced, depending on one the individual sheets or lamellas can overlap more or less, so that from one Normal lamellar screws can be built with different pitches.
Fig. ι der beiliegenden Zeichnung zeigt eine Seitenansicht, Fig. 2 eine Endansicht einer Schraube nach vorliegender Erfindung.Fig. 1 of the accompanying drawing shows a side view, Fig. 2 is an end view a screw according to the present invention.
Jedes Blatt D ist in bekannter Weise mit einer Nabe D1 versehen Die einzelnen Blätter werden beim Aufbau der Schraube der gewünschten Steigung entsprechend gegeneinander versetzt. Soll die Steigung klein werden, so läßt man die Blätter einander wenig überlappen (s. Fig. 1 links), während man eine größere Steigung durch stärkere Überlappung erhält (Fig. 1 rechts). Die einzelnen Blätter werden auf der Welle zweckmäßig mit Nut und Feder befestigt und durch eine Druckschraube in der gewünschten Stellung zueinander gehalten.Each blade D is provided in a known manner with a hub D 1. When the screw is built up, the individual blades are offset from one another according to the desired pitch. If the pitch is to be small, the leaves are allowed to overlap each other a little (see Fig. 1 left), while a greater pitch is obtained through greater overlap (Fig. 1 right). The individual blades are expediently attached to the shaft with tongue and groove and held in the desired position relative to one another by a pressure screw.
