US 7,116,041 B2 · Spark electrode assembly

Abstract

A spark electrode assembly has an elongate electrode with an inner insulator arranged for operable attachment to a support structure. The inner insulator surrounds the electrode with one end of the electrode positioned adjacent a ground element across a spark gap and another end of the electrode extending relative to the support structure for attachment to a source of electrical power. An outer insulator is spaced radially outwardly from the inner insulator and surrounds the inner insulator generally adjacent the end of the electrode adjacent the ground element. The inner and outer insulators cooperate to inhibit the formation of a continuous lubrication layer thereon, thereby establishing an area generally free from the lubrication layer between the end of the electrode adjacent the ground element and the support structure.

Dependent claims

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.
