OIL-BURNER.

Specication of Letters Patent. -.Application filed J une ai,I 1912. Serial No. 704,959.

ratentednay'ao, 1913.

the furnace that the fuel useddoes not cake or carbonize within the burner`andthereby choke the latter and at the same time that the 4parts are cool, enough for an operator to .adjust them while in use without per- 7 sonal discomfort.

This invention relates to a liquid burner for mulie furnaces andthe like wherein the lparts are so protected from the heat of the furnace that the fuel does not become carbonized to clog the burner, means also being provided for regulating the blast and fuel 'supply while the; burner isin opera; ticn without danger of 'injury to the user..V

The invention consists in the matters hereinafter set forth and more particularly pointe-d out in the appended claims. In the drawings, Figure 1 is a view in longitudinal section through a burner that embodies features of the invention; Fig. k2 is a view in longitudinal section, partially broken away, taken at right angles to the plane of view of Fig. 1 Fig. 3 is aview in section taken on or about line- III--III of Fig. 1; Fig. 4 is a view in transverse sec'- tion taken on or about line IV-IV of Fig. 1; and-Fig. 5 is a' view'in section taken on or about line V--V of Fig. 1.

Referring to the drawings, a substantially cylindrical casing 1 has4 a lateral air inlet nipple 2 fitted for connection with a suitable supply pipe." A cap 3 is' screwthreaded on to the rear or `outer end of the casing in such manner las to forma -close jjointtherewit i.

li the counterbored recess. `of the cap lwith i outer contracted end portion 5, that is supplied with jet orificesI 6, concentric with the inner end portion ofthe casing. An inner sleeve f7 of less diameter thanjthe'barrel 554 and with similarly tapered andl apertured end'v 8, is secured concentrically 'within the orfnoz-` zles for muiiie furnaces and the like it is y An outer barrel 4 of less diameter than the casing is. secured at its innerend barrel; with: as' imer end extending into an inner counterbore of the cap 3. An vair duct 9 from the barrel of'- the casing leads to a radial inlet 10 opening into the inner end of the sleeve 7 Access to the passage 1() may be had byremoval of a screw 'plug 11, the aperture in which they latter is screwthreaded-A aHording means for connection with a steam pipe if` it is desired to introduce steam to` the sleeve?.

A stem 12 is rotatably and non-'reciprocally vsecured concentrically in thecasing,

barrel and sleeve, as by means of a. thrust ycollar 13 bearing against a shoulder or flange 14 of the cap 3, a suitable packingv4 gland 15 insuring a tight joint. The inner end.' portion. df the stem whichextends Well beyond the ends 5 `and 8 iof the barrel and sleeve,"is secured to a jet nozzle whose' body 16" is'rotatable on the lbarrel 4 andV whose outer tapered or conical end 18 has a central jet aperture 19. Parallel flanges or slides 20 extending longitudinally of the body 16 yemggagre corresponding ribs 21 on the interior surface of an outer head 22 whose body is screwthreaded on to the casing 1 vand whose outer contracted end 23 has a central vropening 24 substantially in axialjalinement with the opening 19.- The cap 3 has` aboss ornipple 2 5v which is apertured and fitted to form connection with 'a' fuel supply, pipe. A duct 26 connects the bore lof this nip-` `ple or boss with anl annular chamber between the barrel 4 and sleeve 7 through-an annular valve seat` 27. which `co-acts with a needle closure 28 to control passage of Huid therethrough. A .packinggland' or stuifing box 29 affords tight jointfor the stem 28. Appropriate hand wheels 30 and 31 afford means 'for manually`- operating both stems.

In operation manipulation of thel vmain air cooled between the jet and the operators hand. 4As the main fuel passage is annular and `is jacketed both interOrlv-andeX'tel riorly with inrushing air there is little chance for the fuel to become heated ,and carbonized and clog the burner before it reaches the jet. Steam maybe introduced in place of the inner air current if desired by closing the passage 9 and making the proper connection in place of the plug 11. As the parts` are allhoused they do-not become adected by heat or injured by the dust and dirt common in the operation 4of furnaces. t

Obviously, changes inthedetails of con-1 struction may be made without depart-ing 10 from the spirit of the invention and I do not care to limit myself -to' any particular form or arrangement of parts.
