KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Gegenstand der vorliegenden Erfindung ist eine Anbohrrohrschelle, um Röhren oder sonstige Behälter, welche unter innerem Druck stehen, anzubohren.The present invention is a tapping pipe clamp to pipes or to drill other containers that are under internal pressure. Wie aus dem Schnitt Fig. 1 hervorgeht, bildet der Bohrer α einen Bestandtheil der Schelle, indem derselbe in der Schelle verbleibt und das Absperrventil ersetzt. Zu diesem Zwecke trägt der Bohrer, dessen Schaft mit Gewinde versehen ist, eine Scheibe b, welche zu beiden Seiten mit Dichtungen versehen ist, so dafs derselbe in seiner tiefsten Stellung auf dem Rohr und in seiner höchsten Stellung das Innere der Rohrschelle nach aufsen abdichtet. As can be seen from the section in FIG. 1, the drill α forms a component of the clamp in that it remains in the clamp and replaces the shut-off valve. For this purpose the drill, the shank of which is provided with a thread, carries a washer b, which is provided with seals on both sides, so that it seals the inside of the pipe clamp to the outside in its lowest position on the pipe and in its highest position. Da das Gewinde auf dem Schaft des Bohrers beim Anziehen die Spannung bewirkt, so erübrigen sich beim Anbohren Bohrwinkel und Bohrknarre, welche Werkzeuge gewissermafsen ebenfalls mit der Anbohrschelle vereinigt sind.Since the thread on the shank of the drill creates the tension when tightened, so When drilling, drilling angles and ratchets are unnecessary, which tools to a certain extent are also united with the tapping clamp. Nach Durchbohrung der Rohrwand verschliefst also der Bohrer die Oeffnung, so dafs sich jegliche Arbeiten an der bei c anzubringenden Abzweigleitung ausführen lassen, während der Bohrer im übrigen in seiner höchsten Stellung in einfachster Weise ein Abdichten nach aufsen bewirkt.After drilling through the pipe wall, the drill closes the opening, so that any work on the branch line to be attached at c can be carried out while the drill, moreover, in its highest position, is a very simple way of sealing caused outward. Paτent-Anspruch:Patent claim: Eine Rohrschelle zum Anbohren von Röhren u. s. w. unter Druck, bei welcher der Bohrer a zum Durchbohren der Rohrwandung oberhalb seiner Schneide mit einer Scheibe b versehen ist, welche sowohl bei geöffneter, als auch bei geschlossener Zweigleitung als Absperrventil dient, so dafs der Bohrer dauernd einen Bestandtheil der Rohrschelle bildet.A pipe clamp for drilling pipes etc. under pressure, in which the drill a for drilling through the pipe wall is provided with a disk b above its cutting edge, which serves as a shut-off valve both when the branch line is open and when it is closed, so that the drill is a permanent component the pipe clamp forms.
