Abstract:

A reciprocating pipe cutter that uses a thin diameter wire saw as a cutting element. The wire saw blade attaches at one end to a reciprocating blade that can is mounted into a standard electrically powered reciprocating saw tool. The saw wire proceeds from the reciprocating blade, around the perimeter of a fixed pulley and then around the perimeter of a pulley mounted to a swingable arm. The wire terminates at its other end to an extension spring. When the electric tool is turned on, the saw wire reciprocates so that when the wire is pushed into the wall of a pipe, it can cut the pipe in two. The swingable arm allows pipes of varying diameters to be cut. The reciprocating pipe cutting tool allows the user to cut a pipe while it is in place without doing damage to near by surfaces.
