ABSTRACT:
A cutter system for pipe casings and the like, including a generally "C" shaped cutter assembly body having an always open side entry and exit area leading into the centrally located cutter area with an annular trackway extending an exemplary 290.degree. about the operative center of the cutter system. A cutter sub-assembly is carried on the trackway for back and forth movement of an exemplary 110.degree. in each direction with the sub-assembly carrying two, directly opposed rotating cutter blades which cut the pipe casing as the sub-assembly is moved to and from on the trackway. The two blades travel in each direction a minimum of one-half their arcuate spacing difference and preferrably less than their arcuate spacing difference, producing a full 360.degree. cut. The cutters are radially moved in and out by a reciprocating yoke assembly. The cutter body assembly is pivotally mounted onto a telescoping boom attached to for example a work vehicle. An automatic pipe clamp, centering system is included, and all the operative elements are pneumatically or hydraulically driven in association with water cooling lines.
