Abstract
A combination of a pilot burner for issuing fuel out of an outlet thereof and being supplied thereto from a source of the fuel and an electrical probe having an end spaced from the outlet of the pilot burner to provide a spark gap therewith and through which an electrical sparking is adapted to take place to ignite the issuing fuel when the probe is interconnected to a source of electrical energy and the fuel is issuing from the outlet, the end of the probe being disposed beneath the outlet of the pilot burner and defining the spark gap with a diffusion tang of the pilot burner that is disposed adjacent the outlet thereof.
Claims12
In a combination of a pilot burner having means for issuing fuel out of an outlet means thereof and being supplied thereto from a source of said fuel and an electrical probe having an end spaced from said outlet means of said pilot burner to provide a spark gap therewith and through which an electrical sparking is adapted to take place to ignite said issuing fuel when said probe is interconnected to a source of electrical energy and said fuel is issuing from said outlet means, the improvement wherein said end of said probe is disposed beneath said outlet means, said pilot burner having a diffusion tang adjacent said outlet means, said end of said probe defining said spark gap with said tang, said tang having a free end disposed in the path of the fuel issuing from said outlet means, said end of said probe defining said spark gap with said free end of said tang, said free end of said tang and said end of said probe being disposed in substantially vertically aligned relation, said pilot burner being disposed substantially horizontal so that said fuel issues substantially horizontally out of said outlet means until it impinges against said tang, said probe being disposed substantially horizontal in spaced parallel relation to said pilot burner, said end of said probe being bent at substantially a right angle to said probe and extending substantially vertically upwardly toward said free end of said tang, said tang being bent at substantially a right angle to said pilot burner and extending substantially vertically downwardly toward said end of said probe.
In a method of making a combination of a pilot burner having means for issuing fuel out of an outlet means thereof and being supplied thereto from a source of said fuel and an electrical probe having an end spaced from said outlet means of said pilot burner to provide a spark gap therewith and through which an electrical sparking is adapted to take place to ignite said issuing fuel when said probe is interconnected to a source of electrical energy and said fuel is issuing from said outlet means, the improvement comprising the steps of disposing said end of said probe beneath said outlet means, forming said pilot burner with a diffusion tang adjacent said outlet means, forming said end of said probe to define said spark gap with said tang, forming said tang with a free end that is disposed in the path of the fuel to be issuing from said outlet means, forming said end of said probe to define said spark gap with said free end of said tang, forming said free end of said tang and said end of said probe to be disposed in substantially vertically aligned relation, disposing said pilot burner to be substantially horizontal so that said fuel is adapted to issue substantially horizontally out of said outlet means until it impinges against said tang, disposing said probe to be substantially horizontal in spaced parallel relation to said pilot burner, forming said end of said probe to be bent at substantially a right angle to said probe and extend substantially vertically upwardly toward said free end of said tang, and forming said tang to be bent at substantially a right angle to said pilot burner and extending substantially vertically downwardly toward said end of said probe.
