Patentirt im Deutschen Reiche vom 2. April 1878 ab.Patented in the German Empire on April 2, 1878.

Die Neuerung besteht in der Anwendung eines federnden Hebels zur Lagerung der oberen Welle an Bandsägen, d. i. in der Vermeidung der sonst üblichen prismatischen Führung zum Anspannen der Sägen und deren Ersetzung durch eine Geradführung.The innovation consists in the use of a spring-loaded lever for mounting the upper one Shaft on band saws, d. i. in avoiding the otherwise usual prismatic guidance for Tighten the saws and replace them with a straight guide.

In dem beiliegenden Blatt Zeichnungen stellt Fig. ι diese Neuerung an einer Bandsäge dar. ■Bewegt man den Hebel ab um seinen Drehpunkt a, so entfernt sich das Ende b des Hebels seitlich von der Geraden A B. Macht man aber den Drehpunkt α zum Endpunkte eines zweiten Hebels c a, welcher um c schwingt, während man das Ende des Hebels α b bis d verlängert und daselbst in solcher Weise führt, dafs sich d zwar in horizontaler, aber nicht wesentlich in senkrechter Richtung verschieben kann, so wird bei zweckmäfsigen Längenverhältnissen eine Bewegung des Hebelendes b eine Drehung von c d um c bedingen und es wird die Linie A-B eine Curve werden, die sich der Geraden für die Zwecke der Bandsäge vollständig hinreichend nähert.In the attached sheet of drawings, Fig. Ι shows this innovation on a band saw. If you move the lever from around its pivot point a, the end b of the lever moves laterally from the straight line A B. But if you make the pivot point α the end point of a second lever ca, which swings around c , while the end of the lever α b to d is lengthened and there is guided in such a way that d can shift in the horizontal but not essentially in the vertical direction Movement of the lever end b causes a rotation of cd by c and the line AB will become a curve which completely approaches the straight line for the purposes of the band saw.

Man' kann auch das Ende des Hebels a b durch einen am Maschinengestell befestigten schwingenden Hebel R führen. Diese Anordnung ist in Fig. 2 dargestellt und genügt für die praktischen Zwecke bei Bandsägen vollkommen, da die Abweichung des Punktes d von der Horizontalen verschwindend klein ist.Man 'can also result in the end of the lever from swinging by a fixed to the machine frame R lever. This arrangement is shown in FIG. 2 and is completely sufficient for practical purposes in band saws, since the deviation of point d from the horizontal is negligibly small.

Als Vortheile der Anordnung führt der Erfinder an: Einfachheit in der Ausführung, durch Anwendung der elastischen Gliedergeradführung statt der prismatischen gröfsere Elasticität Und daher gröfsere Garantie gegen das Zerspringen der Sägenbänder.The inventor cites the advantages of the arrangement: simplicity in execution Use of the elastic straight chain guide instead of the prismatic greater elasticity And therefore a greater guarantee against the breaking of the saw bands.
