ABSTRACT:
Apparatus for cutting pieces of insulation used to line specially-shaped ductwork, such as radius elbows and O. G. sets. A pair of telescoping trammel tubes are pivotal about a pivot post, and radially movable with respect to the post to assume any desired, graduated, relative position. A cutter wheel is disposed on the end of each of the trammel tubes, and the cutter wheels may be movable from one position wherein they are in line with the trammel tubes, and thus can make a radial cut, to a second position wherein they are disposed substantially 90.degree. with respect to the trammel tubes, and thus can make an arcuate cut with the pivot post generally at the center of the arc. The tubes can be manipulated with respect to the pivot post and with respect to each other, and the cutter wheels may be manipulated with respect to the tubes, so that both radial and true arcuate cuts can be made in insulation to produce an insulation piece of the desired dimensions quickly and accurately.
