Claims (1)

Patent-Anspruch :Patent claim: Schaufelrad für Wasserfahrzeuge, dadurch gekennzeichnet, daß die Schaufeln in ihrem Querschnitt derart dachförmig gestaltet sind, daß sie beim Betriebe mit einer Kante (h10) zuerst in das Wasser einschneiden, und daß die zu beiden Seiten dieser Kante liegenden Schaufelflächen wellenförmig oder zickzackförmig derart ausgebildet sind, daß vorspringende, scharfe Kanten entstehen, gegen welche das von der voreilenden Kante (h10) geteilte Wasser stößt, um so den zum Fortbewegen des Fahrzeuges erforderlichen Widerstand der Schaufel im Wasser hervorzurufen. A paddle wheel for watercraft, characterized in that the cross-section of the paddles is roof-shaped in such a way that when operating they first cut into the water with one edge (h 10 ) , and that the paddle surfaces on both sides of this edge are wavy or zigzag-shaped are that protruding, sharp edges are created against which the water divided by the leading edge (h 10 ) strikes, in order to produce the resistance of the shovel in the water required to move the vehicle.
