Abstract
An incandescent gas mantle assembly includes a metal coupling member and a mantle supporting sleeve member of thermally resistant material that has a skirt portion to which a metal oxide mantle sock is secured in depending relation. The metal coupling member has a body portion of disc configuration with an outer periphery and an inner periphery, a plurality of inwardly extending first coupling portions integral with and spaced about the body portion for attachment to a cooperating burner head, and a plurality of second coupling portions integral with and spaced about the body portion, the second coupling portions being in coupling engagement with recess structure of the mantle supporting sleeve member.
