Abstract
An oil burner includes a pivotal cover that exposes a unitary gun assembly. The gun assembly is movable longitudinally with respect to the central axis of the air tube of the burner by rotating a cam. A spinner assembly is positioned on the gun assembly. The air cone is divided into various surfaces, some of which are at angles to the axis of the air tube. The burner further includes an adjustable air entry port. A work station for facilitating nozzle replacement is also included. The firing rate is controlled by the air entry port setting, the nozzle used, and the position of the nozzle and spinner assembly in the air cone.
Claims49
An oil burner, comprising:
- a housing;
- a gun assembly disposed within said housing, said gun assembly having a longitudinal axis;
- a cam coupled to said gun assembly and said housing;
- and
- movement of said cam causing movement of said gun assembly relative to said housing along said longitudinal axis.
A gun assembly for an oil burner, comprising:
- a body having an oil inlet and a passageway therethrough;
- a nozzle attachment portion;
- and
- wherein said body and said nozzle attachment portion are integrally formed.
An oil burner, comprising;
- a housing;
- a gun assembly including a removable nozzle;
- and
- a work station in said housing, said work station generally conforming to the shape of a portion of said gun assembly for facilitating removal of said nozzle.
An oil burner, comprising;
- a housing;
- a first pin extending from said housing;
- a second pin extending from said housing;
- a cover;
- a slot in said cover disposed about said first pin, said slot having a first end and a second end;
- and
- an arm extending from said cover beneath said second pin, said slot, arm and pins arranged such that said arm prevents said cover from pivoting when said first pin is at or near said first end of said slot but allows said cover to pivot when said first pin is at or near said second end of said slot.
An oil burner, comprising:
- an air cone having a first end, a second end and an axis extending from said first end to said second end;
- a first surface of said air cone angling inward toward said axis with distance from said first end;
- and
- a second surface of said air cone angling inward toward said axis with distance from said first end, the angle between said axis and said second surface being less that the angle between said axis and said first surface.
An oil burner having a housing and an air entry port, said port comprising:
- a projection extending from said housing;
- at least one gap formed in said projection;
- and
- a cover having an extended portion extending toward said housing, said cover disposed adjacent said projection and moveable with respect thereto such that said extended portion can be positioned to cover a portion of said gap.
An oil burner spinners comprising:
- a rim having a front face and a substantially flat rear face;
- a plurality of blades attached to said rim and having a first surface and a second surface;
- said first surface of each of said blades disposed in substantially the same plane;
- and
- said second surface of said blades angled so as to extend behind said rear face of said rim.
