ABSTRACT:
A pipe cutting device for use in cutting pipe and the like for forming saddle cuts or pass through cuts, in the pipe, having a set of rollers to carry the pipe to be cut between upstanding supporting members of the machine and having adjustable torches mounted on the supporting members for effecting the desired cut, the torches being slidably mounted on a horizontal support extended between said upstanding supports and which is adjustable vertically, so that a double or single cut can be selectively performed. Rollers are mounted on bars and provide three supporting surfaces to receive various sizes of pipe, and protractors or other measuring means, are mounted on the device at each pivot point, for presetting to the desired angle and size of cut. This invention is a modification of the invention patented by me on Mar. 16, 1965, U.S. Pat. No. 3,173,979.
