PATENTAMT.PATENT OFFICE.
Die Schrämwerkzeuge gemäß Patent 142004, welche zur Ausübung des Verfahrens gemäß Patent 132643 dienen, können, da sie aus einem mit Zähnen besetzten Körper bestehen und da sie derart auf dem Seil befestigt werden müssen, daß sie schnell ausgewechselt werden können, im Durchmesser nicht so klein gemacht werden, daß durch den Schräm selbst wenig Kohle verloren geht. Andererseits ist es, um einen schmalen Schräm zu erhalten, nicht möglich, Schneidzähne in bekannter Weise zwischen die einzelnen Drähte des Schrämseiles hindurchzustecken, da hierdurch die Festigkeit des sehr fest geflochtenen Seiles leiden würde.The cutting tools according to patent 142004, which are used to carry out the method according to Patent 132643 can serve, since they consist of a body studded with teeth and because they must be attached to the rope in such a way that they can be quickly replaced can not be made so small in diameter that by cutting even little coal is lost. On the other hand, it is to a narrow slant get, not possible, cutting teeth in a known manner between the individual wires of the cutting cable, as this increases the strength of the very tightly braided Seiles would suffer.
Um nun ein Werkzeug zu schaffen, mit welchem einerseits ein sehr schmaler Schräm hergestellt werden und welches andererseits leicht ausgewechselt werden kann, sind bei dem Werkzeug gemäß der Erfindung, welches auf der Zeichnung in den Fig. 1 bis 3 in zwei verschiedenen Ausführungsformen dargestellt ist, nicht an einem Körper mehrere Schneiden angeordnet, sondern die Schneid-Werkzeuge bestehen aus einzelnen Messern, die unmittelbar am Seil befestigt sind.In order to create a tool with which on the one hand a very narrow bevel and which, on the other hand, can easily be replaced, are at the tool according to the invention, which is shown on the drawing in FIGS. 1 to 3 in two different embodiments is shown, not several on one body Arranged cutting, but the cutting tools consist of individual knives, which are attached directly to the rope.
Die zweiteiligen Messer a1 a2, bl b2, von denen je zwei Paar ein Schrämwerkzeug bilden, werden durch Schrauben c am Seil d festgeklemmt.The two-part knives a 1 a 2 , b l b 2 , of which two pairs each form a cutting tool, are clamped to the rope d by screws c.
Befestigt man nun am Seil eine Anzahl der Messer a1 a2 derart versetzt dicht hintereinander, daß sich in Seitenansicht ein Stern ergibt, dann ist die Wirkung eine doppelte, denn der Schräm wird sehr schmal, und durch das Gewicht dieses zusammengesetzten Sternes wirkt das Werkzeug schlagend und reißend zugleich; es stehen aber auch stets einige Messer dem Kohlenstoß wirksam entgegen.If you now attach a number of knives a 1 a 2 to the rope, offset one behind the other in such a way that a star appears in a side view, the effect is twofold, because the cut becomes very narrow, and the tool works through the weight of this composite star striking and tearing at the same time; but there are always a few knives that effectively oppose the collision of coal.
Außerdem kann das Auswechseln sehr schnell und, wenn nötig, sogar während des Betriebes vorgenommen werden.In addition, it can be changed very quickly and, if necessary, even during the Operation.
