Handschere mit Kreismessern.Hand scissors with circular knives.
Patentiert im Deutschen Reiche vom 4. November 1921 ab.Patented in the German Empire on November 4, 1921.
Der Gegenstand der Erfindung betrifft eine Handschere mit Kreismesser zum Schneiden von Blechen u. dgl. derjenigen Art, bei welchen als Schneidwerkzeuge Kreismesser Verwendung finden.The object of the invention relates to hand scissors with a circular knife for cutting of sheet metal and the like of the type in which circular knives are used as cutting tools Find.
Gegenüber den für diesen Zweck bekannt gewordenen Handscheren zeichnet sich die neue Schere bei einfachster und daher billigster Herstellung durch wesentlich einfachere ίο und leichtere Handhabung sowie auch durch vorteilhaftere Wirkungsweise aus.Compared to the hand scissors that have become known for this purpose, the new scissors with the simplest and therefore cheapest production through much simpler ones ίο and easier handling as well as more advantageous mode of action.
Dies wird dadurch erreicht, daß außer den Kreismessern noch in einem bogenförmigen Gehäuse des Handgriffes ein Elektromotor untergebracht ist, der unmittelbar zum Betrieb der an der Außenseite des Gehäuses bzw. an einem besonderen Arm gelagerten Kreismesser dient, wobei die den Strom zuführenden Leitungsdrähte durch den Handgriff hindurchgeführt sind. Hierbei wird das größere am Gehäuse gelagerte Kreismesser von der Achse des Motors durch ein Stirnrädervorgelege in Umdrehung versetzt, während das daruntergelagerte kleinere Kreises messer an einem Schwingarm, der auf der Achse des großen Kreismessers lagert, angeordnet ist, so daß sich das kleine Kreismesser stets selbsttätig in die richtige Lage unter dem großen Kreismesser einstellt, wodurch Bleche von verschiedenen Stärken bearbeitet werden können.This is achieved by the fact that in addition to the circular knives in an arc-shaped one Housing of the handle an electric motor is housed, which is used directly the circular knife mounted on the outside of the housing or on a special arm is used, the ones supplying the current Lead wires are passed through the handle. Here is the larger circular knives mounted on the housing from the axis of the motor through a spur gear reducer in rotation, while the smaller circular knife below it on a swing arm, which is on the Axis of the large circular knife superimposed, is arranged so that the small circular knife always automatically adjusts itself to the correct position under the large circular knife, which makes sheet metal of different strengths can be worked on.
In der Zeichnung ist die Erfindung dargestellt, und zwar zeigt Abb. 1 einen senkrechten Schnitt, Abb. 2 eine Seitenansicht, teilweise im Schnitt.In the drawing the invention is shown, namely Fig. 1 shows a vertical one Section, Fig. 2 is a side view, partly in section.
Die Vorrichtung besteht aus dem Handgriff α, welcher sich nach unten zu bogenförmig erweitert und hohl ist. In dieser bogenförmigen Höhlung liegt der Motor b mit der Achse c. Die Achse c nimmt ein kleines Zahnrad d auf, welches mit dem auf der Achse / sitzenden größeren Zahnrad g kämmt. Die Achse / trägt ferner das Kreismesser h und den Schwingarm i, an dem das kleine Kreismesser I gelagert ist. Der Griff α besitzt eine Bohrung n, durch welche die Leitungsdrähte 0 zu dem Motor b geführt werden. Die Befestigung der Magnete/) kann durch Schrauben o. dgl. erfolgen.The device consists of the handle α, which expands downward into an arc shape and is hollow. The motor b lies with the axis c in this arcuate cavity. The axis c takes a small toothed wheel d on which g is meshed with the on-axis / seated larger gear. The axis / also carries the circular knife h and the swing arm i, on which the small circular knife I is mounted. The handle α has a hole n through which the lead wires 0 are guided to the motor b. The magnets /) can be attached by screws or the like.
