PATENT-ANSPRÜCHE : 
1. Vorrichtung zum Schlitzen von im Bohrloch befindlichen Verkleidungsrohren bei Tiefbohrverrohrungen, dadurch gekennzeichnet, dass das Messer von ein-er-komprimierten Feder (11) längs eines in der Kammer angeordneten Widerlagers (5) nach auf-und auswärts gedrückt wird, gegen welches sich das Messer bei der von oben nach unten, also unter Mitwirkung des   Gestängegewichtes   erfolgenden Schnittbewegung sttitzt.

 which may have to be repeated until the slot is made. The replaceable insert 5 serves as a support for the back of the knife when cutting
PATENT CLAIMS:
1. A device for slotting of casing pipes located in the borehole in deep drilling tubing, characterized in that the knife is pressed upwards and outwards by a compressed spring (11) along an abutment (5) arranged in the chamber, against which the knife supports the cutting movement from top to bottom, that is, with the assistance of the weight of the rod.

Claims (1)

2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass an das Messer hezw. dessen Gleitbacke eine Stange (7) mittels eines entsprechend schwachen Bolzens (6) angelenkt ist, welche im Vereine mit einem in der Kammer befestigten Block (15) die zur Verstellung des Messers dienende Feder (11) in der komprimierten Lage hält und nach nnter Vermittlung eines längs der Rohrwandung gleitenden Anschlages (8) erfolgtem Reissen des Bolzens (6) die Feder frei gibt. 2. Apparatus according to claim 1, characterized in that hezw to the knife. the sliding jaw of which a rod (7) is articulated by means of a correspondingly weak bolt (6) which, in conjunction with a block (15) fixed in the chamber, holds the spring (11) serving to adjust the knife in the compressed position and after mediation a stop (8) sliding along the pipe wall, after the bolt (6) ruptures, releases the spring. 3. Vorrichtung nach Anspruch 1 und 2, dadurch gekennzeichnet, dass die Spiralfeder (11) zwischen dem Kopfe einer mit dem verschiebbaren Messer verbundenen, in einer Hülse (9) eingeführten Stange (13) und dem über dem feststehenden Block' (15) befindlichen Fusse (10) der Hülse angeordnet ist, wobei der Fuss auf dem winkelförmig ausgestalteten, an die Zugstange (7) angelenkten Anschlagarm (8) aufruht und den letzteren federnd an die Rohrwandung presst, um beim Anheben der eingeführten Vorrichtung infolge des sich an eine Rohrkante (16) anlegenden Anschlages stets ein Reissen des Bolzens (6) sicher herbeiführen zu können. 3. Device according to claim 1 and 2, characterized in that the spiral spring (11) is located between the head of a rod (13) connected to the displaceable knife and inserted in a sleeve (9) and the rod (13) above the stationary block (15) Feet (10) of the sleeve is arranged, wherein the foot rests on the angularly designed stop arm (8) hinged to the tie rod (7) and presses the latter resiliently against the pipe wall in order to prevent the inserted device from being raised against a pipe edge (16) applied stop to always be able to safely cause a tearing of the bolt (6). 4. Vorrichtung nach Anspruch 1 bis 3, dadurch gekennzeichnet, dass die Grösse der Auswärtsbewegung des Anschlagarmes (8) durch einen am Körper (1) befestigten Steg (17) begrenzt wird, welcher gleichzeitig dem bei Freigabe der Feder nach abwärts fallenden Anschlagarm als Führung dient und ein Vorragen desselben aus der Kammer (2) in der EMI2.2 4. Apparatus according to claim 1 to 3, characterized in that the size of the outward movement of the stop arm (8) is limited by a web (17) attached to the body (1), which simultaneously serves as a guide for the stop arm falling downwards when the spring is released serves and a protrusion of the same from the chamber (2) in the EMI2.2
