Die vorliegende Neuerung an Anbohrapparaten und Bohrern besteht in der Aushöhlung des Bohrers, der Bohrspindel und der Druckschraube und bezweckt die Hinwegführung sowie das Auffangen der Bohrspäne, damit dieselben nicht in die angebohrte Rohrleitung gelangen, woselbst sie unausgesetzt Schaden an den in den Rohrleitungen sich befindlichen Armaturtheilen verursachen.The present innovation in tapping devices and drills consists in the hollow of the drill, the drill spindle and the pressure screw and is intended to guide away as well as collecting the drilling chips so that they do not get into the drilled pipeline get where they continuously damage those in the pipelines Cause valve parts.
Fig. ι zeigt einen in Verbindung mit der ausgehöhlten Bohrspindel als Hohlkörper construirten Bohrer a, bei welchem sich die Bohrspäne, da dieselben durch ein ziemlich dichtes Schliefsen des Bohrers in die Rohrschelle an einem seitlichen Ausweichen verhindert sind, durch die Zwischenräume der Schneidezacken c in die Höhe und in die Aushöhlung des Bohrers hineindrücken. Das auf diese Weise ausgeschnittene Stück/" klemmt sich in dem Bohrer fest und verhindert, dafs die über demselben sich sammelnden Bohrspäne in die Rohrleitung fallen. Enthält die anzubohrende Leitung eine unter Druck stehende Flüssigkeit, wie dies bei Wasserleitungen der Fall ist, so werden beim Durchkommen des Bohrers die Bohrspäne durch die eindringende Flüssigkeit zurückgedrängt und bei offenem Hahne d ins Freie geleitet. Für diesen Fall genügt ein gewöhnlicher ausgehöhlter Bohrer b, Fig. 2, welcher sich auch insbesondere zum Bohren kleinerer Löcher eignet, wogegen der Bohrer Fig. 1 für die gröfsten vorkommenden Anbohrüngen mit Vortheil angewendet werden kann. Der Hahn d hat den Zweck, dafs man die Ausströmung der Flüssigkeit oder der. Gase nach Belieben absperren kann. Durch das Aufstecken eines Gummischlauches über das oberste Ende der ebenfalls ausgehöhlten Druckschraube e des Anbohrapparates kann man die ausströmenden Flüssigkeiten oder Gase an irgend einen beliebigen Platz leiten. Fig. 1 shows a drill a, constructed in connection with the hollowed-out drill spindle as a hollow body, in which the drill chips, since they are prevented from sideways deflection by the rather tight closing of the drill in the pipe clamp, through the spaces between the cutting teeth c into the Height and press into the cavity of the drill. The piece / "cut out in this way clamps itself firmly in the drill bit and prevents the drill chips that have collected above it from falling into the pipeline When the drill comes through, the drill chips are pushed back by the penetrating liquid and, with the tap d open, are passed into the open. For this case, a conventional hollowed drill b, the tap can be applied the greatest occurring Anbohrüngen with advantage. d has can, that is the outflow of the liquid or, gases at will shut off the purpose. by attaching a rubber hose over the top end of the also hollowed pressure screw E of the Anbohrapparates can lei the escaping liquids or gases to any desired place th.
