The swinging arm I has a projection l8 ers carried by some adjusting means, and at least forming a bell crank with the arm 1 and the one of these has a cutting edge. It is desirable projection is is engaged by one end l9 of the to have these rollers related so they are so spaced 5 spring, the opposite end 20 of the spring being that the thrusts may be more or less balanced braced on the bottom of the channel so that the between the rollers. It is desirable to space the arm 1 is yieldingly held against the screw l2. rollers for large pipe far enough apart to engage When a large pipe such as 2| is to be-cut the the pipe at fairly widely spaced points on the arm 1 is swung back so that a line through the pipe. Such a spacing is too great for a small 10 cutter and tangent to the are described by the pipe. In consequence it has been common to cutter as it swings about its center of support provide several pipe cutters adapted for different will pass between the rollers 3 and 4, thus the sizes of pipe. The present invention is designed cutter roller 9 directly opposes these widely to provide a cutter with different roller spacings, spaced rollers providing a proper relation bethe arrangement permitting of opposing these tween the rollers for this size of pipe, and this rollers having the different spacing with an adspacing may be used for pipes slightly larger justable roller in proper relation to such spacing. and slightly smaller than the pipe 2| providing Further, this is accomplished in a simple way the usual range of a cutter with three wheels. by providing a swinging mounting for the ad- When a small pipe such as 22 is to be cut the justable roller, utilizing the various angles of the arm 1 is positioned so that the tangent to thev swinging mounting to properly oppose the spaced swinging arc of the wheel 9 passes between the rollers.
