Abstract
Abstract An ignition device for vaporizing burners includes an ignition chamber and a liquid fuel tube leading to said chamber. The chamber is also provided with a glow coil ignition member. The mouth of the fuel tube is made of such a material and is placed so near to the glow coil ignition member that it, and the fuel fed through it during the ignition period, is subject to a temperature sufficiently high for causing the fuel in the tube mouth to boil heavily. Hence, small fuel drops are repeatedly shot from the tube mouth towards the glow coil ignition member.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
203 words
A liquid fuel burner device comprising a hollow vaporizing body means, a liquid fuel tube leading to and ending inside said hollow body, glow coil heat producing means inside said hollow body for both initial heating the end of said tube to a temperature which vaporizes the fuel in said tube and thereafter igniting inside said hollow body the vaporized fuel issuing from said tube, the end of said tube being juxtaposed to the internal surface of said hollow vaporizing body with a relationship such that surface tension spreads liquid fuel flowing out the end of said tube over the internal surface of the vaporizing body, a burning chamber means surrounding and communicating with said vaporizing body for burning fuel vaporized inside said body while heating the outside of said body at least to a vaporizing temperature, and means for removing current from said glow coil after the initial ignition period, whereby said heat producing means may be initially activated to vaporize and ignite fuel in said tube and then deactivated after the ignited fuel has heated the vaporizing body to a point where liquid fuel in said tube is vaporized when the surface tension spreads it over the inside of said body.

Claim 3
Dependent Claim
44 words
The device of claim 1 wherein said vaporizing body is cylindrical and said glow coil is mounted coaxially with and inside said cylinder, said end of said tube being centrally lcoated in the cylindrical wall and directed to spray fuel toward said glow coil.
