KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der Patent-Anspruch des Patentes 111376 giebt an, dafs die Flügel des geschützten Propellers die Form von ebenen Kreisscheiben haben, welche durch von den Mittelpunkten ihrer Vorderflächen ausgehende Arme mit der Nabe verbunden sind.The patent claim of patent 111376 states that the blades of the protected propeller are in the form of flat circular disks which by arms extending from the centers of their front surfaces with the Hub are connected.

Seither durchgeführte Versuche haben dahingeführt, die Kreisscheiben durch ovale das schmalere Ende nach innen kehrende Scheiben zu ersetzen, die Arme nicht von den Mittelpunkten, sondern von den äufsersten Umfangsstellen der Scheiben ausgehen zu lassen, und die Arme selbst durch Abplatten und Schrägstellen zu Propellerflügem auszubilden.Tests carried out since then have led to the circular disks being replaced by oval das narrower end to replace inward facing discs, arms not from centers, but to start from the outermost circumferential points of the disks, and to train the arms themselves by flattening and tilting them into propeller blades.

Die beiliegende Zeichnung stellt einen in der vorstehend angegebenen Weise abgeänderten Schraubenpropeller dar, und zwar istThe accompanying drawing represents one modified in the manner indicated above Screw propeller represents, namely is

Fig. ι eine Oberansicht desselben,Fig. Ι a top view of the same,

Fig. 2 eine Hinteransicht, undFig. 2 is a rear view, and

Fig. 3 eine Seitenansicht, währendFig. 3 is a side view while

Fig. 4 einen Propellerflügel in wahrer Gröfse darstellt.Fig. 4 shows a propeller blade in real size.

Wie ersichtlich, haben die ebenen Flügel a ovale Form und wenden die mit kleinerem Krümmungshalbmesser abgerundeten Enden einander zu. Diese Enden berühren einander bei b. As can be seen, the flat wings have a oval shape and turn the ends rounded with a smaller radius of curvature towards one another. These ends touch each other at b.

Die Arme c zur Verbindung der Flügel a mit der Nabe d gehen von den äufsersten Umfangstellen der Flügel ab. Dabei sind diese Arme abgeplattet und derartig schräg gestellt, dafs sie bei der Bewegung des Propellers auch Wasser nach hinten treiben.The arms c for connecting the wings a with the hub d go from the outermost circumferential points of the wings. These arms are flattened and inclined in such a way that they also drive water backwards when the propeller moves.
