ABSTRACT:
Mounting devices are provided for mounting the end portions of a replaceable infrared lamp on the sidewalls of heating chamber formed of a compressed insulation material with sheet metal covers on the outer surface thereof. Each mounting device comprises a ceramic holder having a hollow cylindrical body with a shoulder on the outer end thereof and a bottom wall on the inner end thereof. The bottom wall has a concentric circular opening with diametrically disposed notches. One of the ceramic holders is positioned in each of a pair of opposing holes in the sidewalls with its shoulder secured to the sheet metal cover by a sealant. The lamp is held with its end portions extending through the circular openings in the bottom walls of the ceramic holders so that the metal terminals of the lamp protrude outside the sidewalls. A gasket formed of a resilient refractory material is positioned on each of the end portions of the infrared lamp and tightly packed within the cylindrical body of the ceramic holder so as to provide a gastight joint.
