mittels zweier Kulissensteine H gleitend geführt wird. Der untere Teile der Zugstange ist durch einen Bolzen an einer Grundplatte J befestigt, die durch zwei Federn L gegen eine grössere Anzahl Federn N gedruckt wird. Eine in der Mitte der Zugstange eingeschaltete Zugschraubo M ermöglicht ein beliebiges Verlängern und Verkürzen der Stange. Die er-

schlagen des Meissels bewirkt hat, nimmt die Zugstange zu gleicher Zeit durch die Kulissensteine die Prellung des Schwengels auf und bewirkt, indem die hiedurch in Spannung gebrachten Federn N das Bestreben haben, sich wieder auszudehnen, mit grosser Kraft die Umkehr der Hebelbewegung und ein schnelles Heben des am Hebelarm a angreifenden Bohrgestänges.
Während dieses Vorganges überwindet die entlastete kurbel den toten Punkt. Letzteres ist erleichtert durch die federnd nachgiebige Pleuelstange, da die toten Punkte der Kurbel und der Pleuelstange der Federung wegen nicht gtcicbxeitig erreicht worden können. Indem also die Federn N ihre Aufgabe hinsichtlich der Prellung erfüllt haben, bewirken sie ausserdem eine Ausgleichung des Bohrgestänges und ermöglichen das Wegfallen der toten Gegengewichte. Da die Vermehrung der Federn N für daR praktische Bedürfnis in keiner Weise beschränkt ist, so kann die Ausgleichung des Bohrgestänges und die Aufnahme der Prellung selbst bei grössten Teufen ausgiebig erfolgen. t'ATKNT-ANSt'RÜUHE :

is guided by means of two sliding blocks H. The lower part of the tie rod is fastened by a bolt to a base plate J which is pressed against a larger number of springs N by two springs L. A Zugschraubo M switched on in the middle of the drawbar enables the bar to be lengthened and shortened as required. Which he-

hit of the chisel, the pull rod at the same time takes up the bruise of the pivot through the sliding blocks and, in that the springs N, which are brought into tension, tend to expand again with great force, reversing the lever movement and lifting it quickly of the drill rod acting on the lever arm a.
During this process, the relieved crank overcomes the dead point. The latter is made easier by the resiliently flexible connecting rod, since the dead points of the crank and the connecting rod of the suspension cannot be reached on the side of the suspension. Since the springs N have fulfilled their task with regard to the bruise, they also bring about a leveling of the drill rod and enable the dead counterweights to be eliminated. Since the increase in the number of springs N for practical purposes is in no way limited, the leveling of the drill rod and the absorption of the bruise can be carried out extensively even at the greatest depths. t'ATKNT-ANSt'RÜHE:
