KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der vorliegenden Erfindung ist ein Flossenpropeller für Schiffe, welcher an Stelle eines Schraubenpropellers am Hinterschiff angebracht ist und nach Art der Schwanzflosse der Fische durch Ausschläge nach Steuerbord und Backbord eine vorwärts treibende Bewegung ausübt.The present invention is a fin propeller for ships, which on Place a screw propeller is attached to the stern and according to the type of Tail fin of the fish by swings to starboard and port one forward exercising driving movement.
Dieser Propeller besteht im Wesen, wie aus der beiliegenden Zeichnung ersichtlich,This propeller consists in essence, as can be seen from the accompanying drawing,
ίο welche in Fig. ι die Oberansicht und in Fig. 2 eine Seitenansicht veranschaulicht, aus einem um eine vertikale Achse α schwingbaren zweiarmigen Hebel b, an dessen nach hinten ragendem, längeren Arm eine starre oder elastische Schaufel d ebenfalls um eine vertikale Achse c innerhalb eines festgesetzten . Winkels schwingen kann. Der nach vorn zeigende Arm des Hebels b ist als Gabel oder Kulisse/ausgebildet, in welche der Zapfen g ίο which in Fig. ι the top view and in Fig. 2 illustrates a side view, from a swingable about a vertical axis α two-armed lever b, on the rearwardly protruding, longer arm a rigid or elastic blade d also about a vertical axis c within a fixed one. Can swing angle. The forward-facing arm of the lever b is designed as a fork or gate / into which the pin g
ao einer Kurbel h eingreift, deren Achsei von der Maschinenwelle in geeigneter Weise in Umdrehung versetzt wird. Die Begrenzung der Schwingungsweite der Ruderfläche d kann durch Anschläge k oder dergl. bewirkt werden, welche an besonderen Armen am Ende des Hebels b angebracht sind.ao engages a crank h , the axisi of which is set in rotation by the machine shaft in a suitable manner. The range of oscillation of the rudder surface d can be limited by stops k or the like, which are attached to special arms at the end of the lever b .
Durch den Antrieb mittels der Kurbel h wird der Hebel b derart in Schwingungen nach rechts und links versetzt, daß die Geschwindigkeit der Schaufel d in der Mitte der Schwingung am größten ist und nach den Grenzstellungen hin immer kleiner wird, um hier schließlich gleich Null zu werden. Bei der Umkehrung der Schwingbewegung des Hebels wird infolge des Wasserwiderstandes die Ruderfläche d in ihre andere Grenzstellung umgestellt und drückt nun mit ihrer anderen Fläche auf das Wasser, indem sie in gleicher Weise treibend wirkt, wie vorher. Da die Geschwindigkeit am Ende jeder Schwingung, wie oben bemerkt, gleich Null wird, so erfolgt hier das Umklappen der Schaufel d ohne Stoß.The drive by means of the crank h causes the lever b to oscillate to the right and left in such a way that the speed of the blade d is greatest in the middle of the oscillation and becomes smaller and smaller towards the limit positions, only to finally become zero here . When the swinging movement of the lever is reversed, the rudder surface d is switched to its other limit position as a result of the water resistance and now presses with its other surface on the water, acting in the same way as before. Since the speed at the end of each oscillation, as noted above, equals zero, the shovel d is folded over here without impact.
