Patent ID: 7116041

Claim:
A spark electrode assembly for igniting a combustible gas to lubricate a glassware mold surface, comprising: an electrode, an inner insulator surrounding at least in part said electrode for mounting said electrode to a support structure with an end of said electrode being disposed relative to one side of said support structure for attachment to a source of electrical power and another end of said electrode being positioned adjacent to a ground element across a spark gap, and an outer insulator surrounding at least in part and spaced from said inner insulator adjacent to said another end of said electrode to inhibit electrical leakage from said electrode to the support structure by providing an open space between said inner and outer insulators, said inner insulator having an outer surface with an enlarged mid-section extending radially outwardly from said outer surface, said mid-section having upper and lower portions axially spaced from one another to define at least in part an air passage in said inner insulator.
