ABSTRACT:
Bushings and bushing assemblies for supplying molten vitreous material in the form of exudations to be attenuated into filaments include a heat resistant cushioning material is provided under at least a portion of the flange portion of the bushing to thereby accommodate any thermal expansion of the bushing with respect to the insulation castable refractory material used to cement the bushing in place. The end walls of the bushing are contoured to thereby uniformly distribute the operating stresses occurring in the area of the junction of the flange and the side walls and the end walls of the bushing when the bushing is heated.
