Abstract: A hose cutter tool includes scissor arms joined at a pivot point having opposed jaws, one of which includes a cutter blade and the other of which defines an arcuate support surface to hold tubing material. As the arms are manipulated, the blade descends through and cuts the tubing material.

Abstract: A pipe cutoff apparatus comprises a frame having two frame parts, which are clamped together, wherein said apparatus comprises guides for a cutter device movable around the pipe to be cut. A pipe clamping device with clamping jaws is arranged at one frame part and clamps the pipe in a centered position with respect to the frame.

Abstract: A pipe cutting tool especially adapted to cut the interior of in-the-hole (I-T-H) drill pipe to allow subsequent removal of the pipe above the cut. Due to blasting damage, long sections of I-T-H pipe, otherwise in good condition, cannot be removed because the damaged section prevents the removal of the entire drill string. The tool is adapted to receive power from an external source and includes a frame, a pivoted motor and cutter, and an actuator for pivoting the motor.

Abstract: A pipe cutter is provided whereby a pipe or workpiece is cut from the inside out said cut accomplished by rotating cutters that are mounted on the ends of pivoted sliding guides wherein the guides are pivoted at the end opposite to that of the cutters and the pivoting action expands the end of the guides wherein the cutters are attached and by driving the pivoted sliding guides by a rotating motion the inside wall of the workpiece will be cut.

Abstract: A tube trimming device for cutting each of a plurality of closely spaced projecting tubes an equal distance from a reference or support wall. The device comprises inner and outer tubular housing members that are telescoped together for relative sliding movement through a limited range of travel. A spring extends the two members. A stationary bushing is connected to the projecting end of the inner member to set the desired location of a cutter wheel rotatably mounted on one end of an arm that is pivotally connected to the inner member on the inside. The other end of the pivoted arm has a cam follower that rides on a conical cam surface of the outer member. The tubular inner member is inserted over the projecting end of the tube to be cut, with the stationary bushing pressed against the reference wall. The outer housing is rotatably driven by a motor while, at the same time, the outer housing is pushed toward the reference wall.

Abstract: A pipe cutting device comprises a split frame which may be clamped around the circumference of a pipe (either inside or outside of the pipe). Floatingly or freely mounted on the rollers carried by the frame, to rotate about the pipe, is a ring gear having at least one arcuate arm mounted thereon to rotate with the gear as it turns around the pipe. At one end, the arm is pivotally mounted on the ring gear. At the other end, the arm is selectively biased toward the pipe by a compression spring or other suitable force. This way, a blade mounted on the arm may be driven into the pipe by a controlled amount. A gear train selectively raises or lowers the blade with respect to the surface of the pipe depending upon the position of a clutch arrangement. A special feature of the cutter is that it is easily adapted to cut from either the outside or the inside surface of a pipe.
