Patentirt im Deutschen Reiche vom 26. Mai 1880 ab.Patented in the German Empire on May 26, 1880.

Erfinder sucht die Aufgabe des wiederholten Auffangens und Abschleuderns bei Centrifugalsichtmaschinen dadurch zu lösen, dafs er beide Functionen, getrennt, besonderen dafür construirten Flügelleisten anweist, indem neben bezw. zwischen den bisher gebräuchlichen, centrifugal absthleudernd wirkenden Flügelleisten eine zweite Reihe derartig wirkender Leisten angeordnet sind, welche, entgegengesetzt excentrisch gestellt, das Mahlgut centripetal auffangen, um es von der Sichtgaze abzufangen, einzuziehen und den abschleudernden Flügeln wieder zuzuführen. The inventor seeks the task of repeated catching and throwing off in centrifugal sifting machines to be solved by constructing both functions separately and separately for them Instructs wing strips by in addition to respectively. between the previously used, centrifugal A second row of such acting strips arranged are, which, opposite eccentrically, collect the grist centripetally in order to to catch it from the gauze, to pull it in and to feed it back to the flunging wings.

Man denke sich α b und cd als solche entgegengesetzt excentrisch angeordnete Flügelleisten, im Durchschnitt gezeichnet, um m in der Richtung des Pfeiles, innerhalb des Sichtcylinders ef, drehend, so wird das punktirt markirte Sichtgut von α b nach der Mitte gezogen und von c d nach der Peripherie bewegt werden müssen, Fig. 1. Es entsteht bei mehrfacher Anordnung solcher Flügelpaare gewissermafsen eine centripetal - centrifugal Wechselwirkung, welche ungleich verteilender wirken mufs, als die centrifugale allein.Imagine α b and cd as such oppositely eccentrically arranged wing strips, drawn on the average , rotating by m in the direction of the arrow, within the sight cylinder ef, the visible material marked with dots is drawn from α b towards the center and from cd towards the center the periphery must be moved, Fig. 1. If such pairs of wings are arranged more than once, a centripetal-centrifugal interaction arises, which must have an unevenly distributive effect than the centrifugal interaction alone.

Fig. 2 stellt eine solche Anordnung von acht Flügelpaaren dar, welche beispielsweise um einen inneren Cylinder befestigt sind. Fig. 3 zeigt diese Anordnung für sechs Flügelpaare um und in Verbindung mit entsprechend construirten, um die Welle befestigten Scheiben bezw. Speichen. Diese und weitere ähnliche oder andere Ausführungen sollen nicht zum Wesen der Erfindung gehören.Fig. 2 shows such an arrangement of eight pairs of wings, which for example an inner cylinder are attached. Fig. 3 shows this arrangement for six pairs of wings around and in connection with appropriately constructed washers fastened around the shaft respectively Spokes. These and other similar or other statements are not intended to be Essence of the invention.

Fig. 4 stellt dagegen eine Specialität dar, bei welcher die Fangflügel aus durchlochten Blechen derart wirken, dafs das abzusichtende Mahlgut nicht über die ganze geschlossene Fläche der Fangflügel zu gleiten braucht, um erst durch den Zwischenraum b c, Fig. 1, gewissermafsen in geschlossener Menge in den Bereich der Schleuderflügel zu gelangen, sondern bereits durch die Lochungen der Fangleisten den Schleuderleisten in höchst zerstreuter Menge, gewissermafsen vorgesiebt, zugeführt wird.Fig. 4, on the other hand, represents a specialty in which the catching wings made of perforated metal sheets act in such a way that the ground material to be sealed does not need to slide over the entire closed surface of the catching wings in order to first pass through the space bc, Fig. 1, to a certain extent in a closed quantity to get into the area of the centrifugal vanes, but is already fed to the centrifugal bars in a highly dispersed amount, pre-sieved to a certain extent, through the perforations in the catch bars.

Die Anwendung der Erfindung soll nicht nur auf Sichtmaschinen der Müllerei beschränkt sein, sondern soll auf alle Fälle der Industrie, wo es sich darum handelt, Mengen irgend welcher Art in horizontal geneigten Cylindern durch Flügel gleichmäfsig um die innere Mantelfläche herumzuschleudern, ausgedehnt sein.The application of the invention should not only be limited to milling machines, but should in any case of industry, where it is a question, quantities of any kind to be thrown evenly around the inner surface of the jacket by means of wings in horizontally inclined cylinders, be extended.

Neben bezw. zwischen den bisher gebräuchlichen Schleuderflügeln die Anwendung und Anordnung einer zweiten Reihe Flügelleisten (Zwischenflügel), welche in ihrer Richtung •zu den Schleuderflügeln so gestellt sind, dafs sie in ihrer Verlängerung gegen die letzteren noch auf die nach der Flügeldrehaxe zu gelegene Hälfte der Schleuderflügelfläche treffen und das eingezogene Mahlgut den Schleuderflügeln wieder zuführen.ι. In addition to between the previously used Centrifugal wings the application and arrangement of a second row of wing strips (intermediate wings), which in their direction • are placed in relation to the centrifugal vanes in such a way that they extend against the the latter still on the half of the centrifugal wing area located after the wing rotation axis and feed the ground material that has been drawn in to the centrifugal vanes again. 2. Die Anwendung derart angebrachter und wirkender Flügelleisten (Fangleisten) mit Lochungen bezw. aus gelochten Blechen.2. The use of such attached and effective wing strips (catch strips) with Perforations resp. made of perforated sheets. Hierzu I Blatt Zeichnungen.For this purpose I sheet drawings.
