Abstract
A gas seal for a bell-type annealing furnace is described. A ring supported by the furnace cover and a resilient pad supported by the base mate to form a gas seal when the cover is rested on the base. A cover-supported cooling jacket and a base-supported cooling jacket cooperate to enclose the seal when the cover is rested on the base. Load bearing structure is provided independent of the seal elements to avoid subjecting the seal elements to the weight of the furnace cover.
