Abstract
Abstract An oil burner nozzle for use with liquid fuels and solid-containing liquid fuels. The nozzle comprises a fuel-carrying pipe, a barrel concentrically disposed about the pipe, and an outer sleeve retaining member for the barrel. An atomizing vapor passes along an axial passageway in the barrel, through a bore in the barrel and then along the outer surface of the front portion of the barrel. The atomizing vapor is directed by the outer sleeve across the path of the fuel as it emerges from the barrel. The fuel is atomized and may then be ignited.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
A burner nozzle capable of atomizing a liquid fuel containing combustible particulates, comprising a barrel member having an unrestricted inner passage extending to the exterior of said nozzle for conveying said fuel to an outlet located exteriorly of said nozzle, said barrel member having an outer passageway disposed around said inner passage for conveying atomizing vapor towards the forward end portion of said barrel member and outward laterally therefrom, and means including a sleeve member held over said barrel member and forming with said forward portion a converging chamber extending to said outlet to direct said vapor across said outlet for atomizing said fuel exteriorly of said nozzle.
Claim 2
Dependent Claim
108 words
A burner nozzle capable of atomizing a liquid fuel containing combustible particulates, comprising a barrel member having an unrestricted inner passage extending to the exterior of said nozzle for conveying said fuel to an outlet located exteriorly of said nozzle, said barrel member having an outer passageway disposed around said inner passage for conveying atomizing vapor towards the forward end portion of said barrel member and outward laterally therefrom, and means including a sleeve member held over said barrel member and forming with said forward portion a converging chamber extending to said outlet to direct said vapor across said outlet for atomizing said fuel exteriorly of said nozzle.
Claim 3
Dependent Claim
65 words
A burner nozzle according to claim 1, said barrel member having a borehole formed centrally therein, said borehole having a first diameter in the rearward portion of said barrel member and narrowing to a reduced diameter portion in said forward portion, and a pipe member fitted to said reduced diameter portion of said borehole to form said inner passageway therethrough and said outer passage therearound.
Claim 4
Dependent Claim
25 words
A burner nozzle according to claim 2, the outer surface of the forward portion of said barrel member being recessed to form said converging chamber.
Claim 5
Dependent Claim
38 words
A burner nozzle according to claim 1, 2 or 3, the front portion of said barrel member being beveled with at least one groove formed therein, said sleeve member extending over said beveled front portion and abutting thereon.
Claim 6
Dependent Claim
19 words
A burner nozzled according to claim 4, including a plurality of said grooves each extending obliquely toward said outlet.
