  Kupplungsvorrichtung für Schlangenbohrer.

 <Desc/Clms Page number 2> 

 diesem Zapfen lässt, sich der Bohrkopf im aufgeschobenen Zustande, wie aus Fig. 5 zu erkennen ist, hin und her schieben und um diesen drehen. Ist er um den Zapfen Fin die Richtung der Achse des Bohrschaftes gedreht, so lässt er sich mit dem achsialen Schlitz n auf dem Zapfen   l   nach abwärts schieben, so dass die ausgerundete Öffnung p des Schwanzendes des Bohrkopfes über den Ansatz i greift, wodurch die Verbindung hergestellt ist. 



  Beim Bohren wird die Verbindung unbedingt aufrecht erhaben, da eine Drehung des Bohrkopfes um den Zapfen   l   nicht mehr möglich ist. Beim Zurückziehen des Bohrers kann der Bohrkopf im Bohrloch nicht'stecken bleiben.

 With this pin, the drill head can be pushed back and forth in the pushed-on state, as can be seen from FIG. 5, and rotated about it. If it is rotated around the pin Fin in the direction of the axis of the drill shaft, it can be pushed downwards with the axial slot n on the pin l, so that the rounded opening p of the tail end of the drill head engages over the shoulder i, thereby creating the connection is made.



  When drilling, the connection is absolutely upright, since it is no longer possible to rotate the drill head around the pin l. When the drill is withdrawn, the drill head cannot remain in the drill hole.

PATENT. ANSPRUCH : Enpplungsvorrichtung für Schlangenbohrer, bei welchen der Bohrerschaft und der Bohrkopf durch eine oben gegabelte Muffe verbunden sind, dadurch gekennzeichnet, dass die Muffe aus schmiedbaren Guss bis an die Gabelenden das DraUproS ! des Bohrerschaftes hat und in der Gabel den nach oben abgerundeten Ansatz fi) besitzt, über welchen mit dem dementsprechend abgerundeten Ausschnitt (p) das Schwanzende des mittels Quer- riegel dz m) am längeren Gabelende verschiebbar gehaltenen Bohrkopfes geschoben wird. PATENT. CLAIM : Application device for auger bits, in which the drill shaft and the Drill head are connected by a sleeve forked at the top, characterized in that the sleeve is made of forgeable cast up to the fork ends the DraUproS! of the drill shaft and in the fork has the upwardly rounded attachment fi), over which the tail end of the drill head, which is held displaceably at the longer fork end by means of transverse bolts dz m), is pushed with the correspondingly rounded cutout (p).
