Abstract
A soil pipe cutting device comprising a pair of pivotally interconnected arm members having jaw ends and actuator ends and a flexible, non-extendable cutter chain adjustably mounted between the jaw ends to circumscribe a pipe to be cut is provided with a screw-type actuating mechanism for displacing the jaw ends in the direction to tension the cutter chain to sever a pipe, and with a handle removably and adjustably mounted on the actuator end of one of the arms for transporting the cutter and for supporting and manipulating the cutter during a pipe cutting operation.
Claims24
A pipe cutting device comprising, first and second arms each having a jaw end and an actuator end, means interconnecting said arms for pivotal displacement about a jaw axis extending in a given direction transverse to the longitudinal direction between the jaw and actuator ends thereof, displacement of the actuator ends in one of the directions away from one another displacing the jaw ends toward one another, a flexible, non-extendible cutter chain adjustably mounted between the jaw ends of said arms to circumscribe a pipe to be cut and having a plurality of cutting elements thereon, a threaded actuator rod, means interconnecting said rod with the actuator ends of said arms for rotation about a rod axis spaced from and transverse to said jaw axis and for rotation of said rod in opposite directions about said rod axis to displace said actuator ends toward and away from one another, means for rotating said rod in said opposite directions, and a handle mounted on the actuator end of only one of said arms, said handle including a first end attached to said actuator end of said one arm and a gripping end extending from said first end transverse to said given direction.
A pipe cutting device comprising first and second arms each having a jaw end and an actuator end, each of said arms being pivotally mounted about a given axis transverse to the longitudinal direction between the jaw and actuator ends thereof, whereby displacement of the actuator ends away from each other displaces the jaw ends toward each other, a flexible, non-extendable cutter chain having a plurality of cutting elements thereon and adjustably mounted between said jaw ends of said arms to circumscribe a pipe to be cut as said chain is wrapped around said pipe and tightened by said jaw ends being displaced toward each other, an actuating means for displacing said actuator ends of said arms toward and away from one another with only one of said actuator ends having a structural extension and a manually manipulated handle separate from said actuating means and removably attached to said structural extension.
