Gebläseflügel.
Patentiert im Deutschen Reiche vom 29. Januar 1911 ab,Fan blades.
Patented in the German Empire on January 29, 1911,

Der Gegenstand vorliegender Erfindung bezieht sich auf eine Konstruktion von Gebläseflügeln, die bei unregelmäßigem Gang der Maschine einen möglichst gleich starken Luftzug erwirken sollen. Die Anordnung ist folgende: Auf Welle α ist die Nabe, mit den Flügeln verbunden, aufgekeilt. Es sind dieses die Flügel b, welche etwa zur Hälfte ihres Flächeninhalts ausgeschnitten sind, in zwei oder mehreren Fächern, wie bei c ersichtlich. An beiden Seiten bleibt die Verbindung bestehen, auf der der Führungsrahmen h angebracht wird. In dieser Führung bewegt sich leicht der Schieber d, welcher so hergestellt ist, daß er die ausgeschnittenen Fächer beim Stillstand der Maschine völlig deckt. Beim Rotieren der Flügel tritt die Kugel, wie ersichtlich, in Tätigkeit; sie hebt den Schieber d, und je nach der Geschwindigkeit öffnen und schließen sich die Ausschnitte c im Flügel b. Der Wirkungsgrad kann durch Spannen der Spiralfeder f vermittels der Überwurfmutter g, gegen dessen obere Wand dieselbe drückt, eingestellt werden.The subject matter of the present invention relates to a construction of fan blades which are intended to produce as equally strong a draft as possible when the machine is running irregularly. The arrangement is as follows: The hub, connected to the blades, is keyed on shaft α. These are the wings b, which are cut out to about half of their area, in two or more compartments, as can be seen at c. The connection on which the guide frame h is attached remains in place on both sides. The slide d, which is manufactured so that it completely covers the cut-out compartments when the machine is at a standstill, moves slightly in this guide. As can be seen, when the wings rotate, the ball comes into action; it lifts the slide d and, depending on the speed, the cutouts c in the wing b open and close. The efficiency can be adjusted by tensioning the spiral spring f by means of the union nut g, against the upper wall of which it presses.
