KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
An Schrämeinrichtungen, welche gemäß der Patentschrift 132643 dadurch einen Schräm im Kohlenabbaustoß erzeugen, daß durch seitlich des Stoßes aufgestellte Antriebsmaschinen eine Kette (Seil) am Stoß hinbewegt wird, welche mit einem Werkzeug ausgerüstet ist, ist es nötig, da die Kette oder das Seil sich verdrehen, daß das Werkzeug stets dem Stoß entgegensteht, um wirken zu können.At Schrämeinrichtungen, which according to the patent 132643 thereby a Schräm generate in the coal mining face that by driving machines set up at the side of the face a chain (rope) is moved towards the joint, which is equipped with a tool, it is necessary, as the chain or rope twist, that the tool is always subject to impact opposes in order to be able to work.
to Zu diesem Zwecke ist als Schrämwerkzeug ein Körper zur Verwendung gekommen, welcher an seinem Umfange mit radial stehenden festen oder auswechselbaren Schneidezähnen besetzt ist.to For this purpose, a body was used as a cutting tool, which around its circumference with radially standing fixed or exchangeable incisors is busy.
Sind nun die Kohlenflöze von Bergemitteln durchzogen, dann hat sich ergeben, daß das aus der Patentschrift 142004 bekannte Schrämwerkzeug an den Steinen besonderen Widerstand findet; hierdurch wird der Arbeitsprozeß ein reißender, da die Zähne bisher nicht so klein und doch scharf gestaltet werden konnten,- daß sie das Gestein mit durchschneiden. Auf der Zeichnung ist ein Werkzeug dargestellt, welches vorbeschriebene Übelstände beseitigt.If the coal seams are now traversed by mountain means, then it has turned out that that from the patent 142004 known cutting tool on the stones special resistance finds; This makes the work process a tearing one, since the teeth have not been so up to now could be made small and yet sharp - that they cut through the rock with them. In the drawing, a tool is shown, which the above-described inconveniences eliminated.
Der Körper α, welcher durch Schrauben, Stellringe o. dgl. am Seil (Kette) s befestigt wird, ist an seinem Umfange mit Feilenhieben versehen, wodurch scharfe Schneidflächen oder Schneidezähne gebildet werden.The body α , which is attached to the rope (chain) s by screws, adjusting rings or the like, is provided with file cuts on its circumference, whereby sharp cutting surfaces or incisors are formed.
Der Körper kann im Querschnitt rund (Fig. 1) oder kantig (Fig. 2) ausgebildet sein.The cross-section of the body can be round (FIG. 1) or angular (FIG. 2).
Die Drähte von Schrämseilen feilenartig aufzurauhen, ist zwar schon vorgeschlagen; hiermit ist indessen der Ubelstand verbunden, daß das Schrämseil über Gebühr geschwächt wird.Roughening the wires of the cutting ropes like files has already been proposed; this, however, is associated with the disadvantage that the cutting rope is unduly weakened will.
