A catalytic converter for removing noxious pollutants from an engine exhaust gas stream is described which permits expansion and contraction of the conversion chambers without their warping and which ensures a maximum exposure of the exhaust gases moving through the converter to the catalytic material. The device consists of an elongated outer shell closed at its ends by a pair of caps, with an inlet conduit projecting through the other cap. The inlet and outlet conduits are in open communication with the interior of the converter. A pair of conversion chambers adapted to hold the catalytic material are mounted in the shell between the inlet and outlet conduits. The chambers, which are provided with a pair of opposed perforated walls for passage of the exhaust gases, are rigidly connected to the outer shell at their opposed ends. The adjacent ends of the chambers are slidably interconnected to permit the chambers to expand and contract with respect to each other and with respect to the outer shell. (Air Pollut. Abstr.)
