Zusatz-Patent zu No. 8689 vom 23. August 1879.Patent addition to No. 8689 of August 23, 1879.

Patentirt im Deutschen Reiche vom 19. Februar 1880 ab. Längste Dauer: 22. August 1894.Patented in the German Empire on February 19, 1880. Longest duration: August 22, 1894.

Die Einströmungsöffnung liegt oberhalb des Gehäuses, die Ausströmung seitlich, und zwar sind beide so angeordnet, dafs die Punkte a, r und d in einer geraden Linie liegen, während b und c so gewählt sind, dafs, wenn s Punkt b berührt, die Spitze η des Flügels den Punkt c um ein wenig überschritten hat.The inlet opening is above the housing, the outlet on the side, and both are arranged so that points a, r and d lie in a straight line, while b and c are chosen so that when s touches point b , the tip η of the wing has exceeded point c by a little.

Durch die Anordnung der Punkte α und d wird erreicht, dafs der Flügel mit der Spitze m die Einströmung schliefst, sobald er mit η die Ausströmung öffnet, und die Kante b dichtet an dem Schaufelbogen m s so lange ab, bis die Spitze η die Dichtung bei c übernimmt.The arrangement of the points α and d ensures that the wing with the tip m closes the inflow as soon as it opens the outflow with η , and the edge b seals against the blade arc ms until the tip η closes the seal c takes over.

Die Schaufeln sind in der aus der Figur ersichtlichen Weise geformt, so dafs die Stirnwände derselben den linsenförmigen Umrifs behalten, während die Schaufelflächen nur je eine Hälfte der Umrifscurve umschliefsen und sich in der Mitte an den Zapfen ζ anlehnen, so dafs zwei Hohlschaufeln entstehen, welche mit ihrer concaven Fläche die Luft treiben.The blades are shaped in the manner shown in the figure, so that the end walls of the same retain the lens-shaped contour, while the blade surfaces each enclose only half of the circumferential curve and lean against the pin ζ in the middle, so that two hollow blades are created which drive the air with their concave surface.

Die Führung der Schaufeln im Punkte r soll durch ein Gleitstück, welches in dem punktirten Flügel angedeutet ist, erfolgen, wobei jedoch zu bemerken ist, dafs der Zapfen des Gleitstückes nicht im Deckel, sondern in einem an das Gehäuse geschraubten Arme gelagert wird. Ein derartiger Ventilator, mit Riemscheibe versehen, soll für sich allein arbeiten. Für gewisse Zwecke ist es jedoch vortheilbaft, zwei Ventilatoren in der durch Zeichnung angegebenen Weise mit einander zu verbinden, so dafs die beiden Kurbelscheiben auf einer gemeinschaftlichen, durch Riemen oder Räder vorgelege betriebenen Welle sitzen, wobei die beiden Kurbelzapfen um i8o° gegen einander verstellt sind. Die beiden AusströmungsöffnuBgen werden alsdann durch ein gebogenes Rohr, an welches sich das Windleitungsrohr anschliefst, verbunden.The blades at point r should be guided by a sliding piece, which is indicated in the dotted wing, whereby it should be noted, however, that the pin of the sliding piece is not mounted in the cover but in an arm screwed to the housing. Such a fan, provided with a pulley, should work on its own. For certain purposes, however, it is advantageous to connect two fans with one another in the manner indicated in the drawing, so that the two crank disks sit on a common shaft driven by belts or gears, the two crank pins being offset from one another by 180 ° . The two outflow openings are then connected by a bent tube to which the wind conduction tube is attached.
