KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Den Gegenstand der vorliegenden Erfindung bildet eine Bohrmaschine, welche zum Vortreiben von Stollen mit kreisförmigem Querschnitt in Kohlen-Bergwerken Verwendung finden soll.The subject of the present invention is a drilling machine which is used for propulsion of tunnels with a circular cross-section in coal mines use should find. In der Zeichnung wird der neue Streckehbohrer veranschaulicht, welcher sich von anderen ähnlich wirkenden Vorrichtungen dadurch scharf unterscheidet, dafs die Bohrwerkzeuge sich um die eigene Achse drehen und gleichzeitig eine Kreisbewegung um einen gemeinsamen Mittelpunkt ausführen. Diese gleichzeitige Bewegung erzielt einen aufserordentlich hohen Nutzeffect und ist bisher in ähnlicher Art nicht zur Anwendung gelangt. ■The drawing illustrates the new extension drill, which differs from others similarly acting devices are sharply distinguished by the fact that the drilling tools turn around rotate its own axis and at the same time make a circular movement around a common center carry out. This simultaneous movement achieves an extraordinarily high efficiency and has so far not been used in a similar manner. ■ Auf einem auf drei Rädern α ruhenden Gestell b ist eine Kraftquelle, wie Elektromotor oder dergleichen, angebracht; der Antrieb für dieselbe geschieht mittelst eines Vorgeleges von der Bohrkreuzwelle c aus. Auf der Stirn dieser Welle c sitzt das Bohrkreuz d, welches zweckmäfsig aus Armen von ungleicher Länge besteht und die Bohrwerkzeuge e trägt, die auf zweckmäfsige Weise, wie durch Rädervorgelege, Gall'sche Kette oder dergleichen, von der Bohrkreuzwelle c aus in Drehbewegung um die eigene Achse versetzt werden können. Zufolge der Drehbewegung des Bohrkreuzes d werden die Löcher, welche die Bohrwerkzeuge erzeugen, die aus stählernen Schneidescheiben, Messerscheiben oder dergleichen bestehen können, zu concentrischen Ringfurchen erweitert. Der Vorschub der Maschine wird dadurch bewerkstelligt, dafs durch eine Schneckenradübersetzung, Gall'sche Kette oder dergleichen, von der Bohrkreuzwelle e aus eines der Wagenräder angetrieben und somit der Wagen, der Wirkung der Schneidezeuge folgend, selbstthätig vorgeschoben wird. Der aus dem Gestein bezw. der Kohle herausgeschrämte cylindrische Kern wird durch leichte Hammerschläge oder dergleichen entfernt, hinter der Maschine abgelegt und von dort aus, wie üblich, durch Wagen oder dergleichen entfernt.A power source, such as an electric motor or the like, is attached to a frame b resting on three wheels α; the drive for the same takes place by means of an intermediate gear from the drill cross shaft c . At the end of this shaft c sitting d the Bohrkreuz consisting zweckmäfsig of arms of unequal length, and the drilling tools carries e, which, as c on judicious manner by wheel gear, Gall'sche chain or the like, from the Bohrkreuzwelle into rotational movement about the own axis can be offset. As a result of the rotary movement of the drill cross d , the holes which the drilling tools produce, which can consist of steel cutting disks, knife disks or the like, are widened to form concentric annular grooves. The advance of the machine is brought about by the fact that one of the carriage wheels is driven by a worm gear transmission, Gall's chain or the like, from the drill cross shaft e , and thus the carriage is automatically advanced following the action of the cutting tools. The respectively from the rock. The cylindrical core cut out of coal is removed by light hammer blows or the like, placed behind the machine and from there, as usual, removed by carts or the like.
