   Erwelterunge-Bohrkrone für Tiefbohrung. 



   Die den Gegenstand der Erfindung bildende Erweiterungs-Bohrkrone ist oberhalb der gewöhnlichen, den Durchmesser der lichten Weite der Futterrohren des Bohrloches besitzenden Bohrkrone angeordnet und mit mehreren als   Längsfedern   ausgebildeten Werkzeugträgern versehen, welche aus schwalbenschwanzförmigen Längsnuten hervorragen. Da ferner die lichte Weite der erweiternden Bohrkrone dem   Ausmasse   der entstehenden Bohrkrone entspricht, können letztere unbehindert in das oberhalb angeschraubte Kernrohr hinauf treten, so dass auf diese Art drei Operationen, nämlich : Bohren, Kerngewinnen und Erweiterung des Bohrloches, zum Zwecke des freien Nachfolgen der Futterrohren gleichzeitig erfolgen. 



   In untenstehender Zeichnung veranschaulichen die Fig. 1-3 die Bohrkrone in Ansicht, Längsschnitt und Querschnitt. 



   Oberhalb der gewöhnlichen Bohrkrone, die, wie erwähnt, einen Durchmesser besitzt, welcher der lichten Weite der Futterrohren des Bohrloches entspricht, befindet sich die zweite Bohrkrone a, welche ans mehreren zu Längsfedern ausgebildeten   Werkzeugträgern   b besteht, die so angenietet sind, dass sie aus den schwalbenschwanzförmigen Längsnuten c hervorragen. jedoch in die obgenannten Längsnuten federnd zurücktreten, sobald die Bohrkrone in die   FuttclTohre. 1Ünaufgehoben   wird. 



   PATENT-ANSPRÜCHE : 
1. Erweiterungs-Bohrlironc für   Tiefbohrapparate,   gekennzeichnet durch über der gewöhnlichen Bohrkrone angeordnete, als Längsfedern ausgebildete   Werkzeugträger,   welche in Längsnuten derart angeordnet sind, dass die von ihnen getragenen Werkzeuge in freiem Zustande dem   äusseren   Durchmesser der   Rohrtour   entsprechend aus der Bohrkrone vorstehen, beim Passieren der Rohrtour jedoch, dem inneren Durchmesser der letzteren sich selbsttätig anpassend, in die Längsnuten zurücktreten.

   Advanced drill bit for deep drilling.



   The expansion drill bit forming the subject of the invention is arranged above the usual drill bit, which has the diameter of the inner width of the casing of the drill hole, and is provided with several tool carriers designed as longitudinal springs which protrude from dovetail-shaped longitudinal grooves. Furthermore, since the clear width of the expanding drill bit corresponds to the dimensions of the drill bit being created, the latter can step up into the core tube screwed on above without hindrance, so that in this way three operations, namely: drilling, core extraction and widening of the borehole, for the purpose of freely following the Casing pipes take place at the same time.



   In the drawing below, FIGS. 1-3 illustrate the drill bit in a view, longitudinal section and cross section.



   Above the usual drill bit, which, as mentioned, has a diameter which corresponds to the inside width of the casing of the borehole, there is the second drill bit a, which consists of several tool carriers b designed as longitudinal springs, which are riveted so that they consist of the dovetail-shaped longitudinal grooves c protrude. however, resiliently withdraw into the above-mentioned longitudinal grooves as soon as the drill bit is in the FuttclTohre. 1 is repealed.



   PATENT CLAIMS:
1. Extension Bohrlironc for deep drilling apparatus, characterized by tool carriers designed as longitudinal springs and arranged above the ordinary drill bit, which are arranged in longitudinal grooves in such a way that the tools carried by them protrude from the drill bit in a free state corresponding to the outer diameter of the pipe tour when passing of the pipe tour, however, automatically adapting to the inner diameter of the latter, step back into the longitudinal grooves.

** WARNING ** End of DESC field may overlap beginning of CLMS **.
