Device for cutting pipes

A pipe cutter for cutting pipes of plastics material, said cutter comprising:

• a split yoke configured to clamp on a pipe to be cut, a saddle guided against one end face of the yoke and movable on the yoke to rotate around the axis of the yoke, and a cutter disposed on a cutter holder mounted on the face of the saddle remote from the said yoke and operable to engage and cut the pipe in the region outside of the said split yoke and the said saddle as the saddle moves around the yoke, said yoke comprising two semicircular parts pivoted to each other at one of their ends, and a clamp to clamp the other ends together whereby a pipe may be inserted into the cutter when the yoke is in the opened position, and said saddle being circular and also formed of two portions, the said saddle having an in-turned flange engageable with an internal circumferential slot in the yoke, said two portions at one of their respective adjacent ends being joined by a connecting link, said link being pivoted to said adjacent ends, said other ends of said portions being engageable by a protuberance on one end engaging in a socket in said other end, whereby when the hinged portions of the yoke and saddle are aligned, said yoke and saddle can be opened and closed simultaneously, and means for rotating the said saddle on the said yoke when the said yoke is in the closed position.
