Abstract
A cutter for a helically corrugated tube in which a pair of rings are connected by a blade carrier to form a track around the tube. Each of the rings comprises a pair of "C" members hingedly connected at one end and releasably connectable at the other end to form the ring. Each "C" member has a pair of rails supporting a circumferentially movable carrier having rollers at each end engaging the rails of the adjacent pair of rings. A holder on the carrier projects outwardly between the rails. A yoke in the holder carries the cutting blade; a compression spring in the holder drives the yoke and blade toward the tube. A threaded cup on the holder adjusts the compression spring and also provides a handle recess.

- said corrugated pipe having a helical ridge and a helical trough defining the corrugation;
- said cutter comprising a pair of rings;
- means for securing said pair of rings around said pipe;
- each ring having a transverse dimension at least equal to the distance between two adjacent runs of helical ridge;
- each ring having a track;
- a blade carrier riding in the track of each ring;
- a cutting wheel blade positioned in said blade carrier;
- said rings and said tracks being interconnected by said blade carrier;
- means on said blade carrier biasing said blade toward said pipe;
