  Luftschraube mit unstarren Flügeln. 



     Du Erfindung   hat den Zweck, die in dem Patent Nr. 42844 beschriebene Luft-   schraube weiter auszubilden oder zu verbessern. Bei Luftschrauben dieser Art verursacht   es, besonders bei Wind, grosse Schwierigkeit, die Schraube in Bewegung zu setzen, da jeder Flügel nur an einem einzigen Punkt hängt und infolgedessen keine bestimmte Lage hat. 



  Wenn   aber die Schraube schon   in Bewegung gesetzt ist, so macht jeder Flügel eine pendelnde Bewegung um seine Gleichgewichtlage. Diese Nachteile werden durch die vor-   liegende Erundung beseitigt.   



   Der Gegenstand der Erfindung ist auf der Zeichnung dargestellt und zwar gibt Fig. 1 eine Aufsicht auf eine Luftschraube gemäss Fig. 2 des Patentes Nr. 42844 jedoch mit 6 Flügeln, während Fig. 2 eine abgeanderte Form des Erfindungsgegenstandes veranschaulicht.

   werden.   Dadurch aber üben sie auf die Flügel 6 einen Zug in der Richtung des Umfanges aus, so dass die Flügel straff gespannt werden, also das schädliche Flattern derselben auf diese Weise verhindert wird. 



   Durch eine zweckmässige Anbringung des Seiles oder der Kette ist es ferner möglich,

  Propeller with fixed wings.



     The purpose of the invention is to develop or improve the propeller described in patent no. 42844. With propellers of this type, it is very difficult to set the propeller in motion, especially when there is wind, since each wing only hangs at a single point and therefore has no particular position.



  But if the screw is already set in motion, each wing makes a pendulum motion around its equilibrium position. These disadvantages are eliminated by the present investigation.



   The object of the invention is shown in the drawing, namely FIG. 1 shows a plan view of a propeller according to FIG. 2 of patent no. 42844 but with 6 blades, while FIG. 2 illustrates a modified form of the object of the invention.

   will. As a result, however, they exert a pull on the wings 6 in the direction of the circumference, so that the wings are tensioned taut, that is to say the damaging fluttering of the same is prevented in this way.



   By appropriately attaching the rope or chain, it is also possible
