' Un i'rED STAWENT ortion.



. This invention relates to burners `for the combustion yof fuel for heating purposes, and

` especially to those whereby steam `or other suitable fluid under pressure and oil or other combustible fuel are mixed, atomized, and

discharged, combustion taking place at or near the pointf of discharge.r

Improvements are made by this invention in thetype of `burner shown in my United States Letters Patent No. 792,265, issued June 13, 1905.

Simple and improved means'are provided by the s flow of either heavy or light fuel isv produced and the fuel mixed and discharged with the fluid entering the burner under pressure, the elements being broughtl to the proper degree of heat during passage through the burner. The invention further provides improvements in the details of structure and parts whereby an assembled device of few parts is produced which is simple, strong,I efficient,

and economical. A

The Adetails of construction and arrangement of parts contemplated by this invention are disclosed in the accompanying drawings, forming part hereof, wherein a preferable embodiment of the invention is shown for purposes of illustration and in which like reference characters refer to corresponding parts in the several views, whereof- Figure 1 is an outer view of the burner. Fig. 2 is a central longitudinal sectional view. Fig; 3 is a cross-sectional view onthe. line z z, Fig. 2. Fig. 4 is a cross-sectional view on the line y y, Fig. 2; and Fig. 5 is a cross-sectional f view on the line a; Fig. 2.

Referring more particularly tothe drawings, 6 designates an kouter casing'or shell. This casin comprises an elongated portion 7 and an en arged portion S, the two portions being preferably integrally formed. The elongated portion 7 at its free end constitutes a part of the discharge end ofthe burner, where it is interiorly contracted to form converging surface 9, whereby the material pass- Specicaton of Letters Patent.

ing out of casing 6 is converged or contracted. Enlarged portion 8 forms a chamber 10, and through this portion of casing 6 is formed'an entrance 11 to chamber 10, the entrance being interiorly rscrew-threadedv vfor the reception of a supply-pipe. The open or free-end 1'2 of casing 6 is interiorly screw-threaded.

' Into the screw-threaded end 12-is screwed a vmember comprising an outer casing 13,y a-

substantially transverse portion 14, and an inner casing 15, these parts being integrally formed and producing a chamber 16 andk a continuous passa e therefrom to the discharge end ofthe urner.

Casing 13 is preferably coincident in thickness and transverse dimension with portion 8 of casing 6, to which it is jointed at its reduced screw-threaded part 17. It is interiorly screw-threaded at its other or outer end. Through casing 13 is formed an 'entrance 18 to chamber 16.

Portion 14 constitutes a transverse partition between chambers 10 and 16 and is provided with an aperture or opening 19, said openinggradually'decreasing in width from chamber 16 to where it merges with the interior of inner casing 15.

Inner casing 15 extends from portion 14 and opening 19 through chamber 10 andportion 7 of casing 6 to the discharge end of the burner. The outer surface of the portion of casing 15 passing through ortion 7 is removed from and substantial y parallel with" the inner surface of portion 7 except at the.

discharge end, a'continuous passage between the two casings thus being formed. At the discharge end casing 15 has a beveled exterior surface 20 complementary to. surface 9 and with this latter surface forming a converging opening. The interior of casing 15 gradually increases in size from opening 19 to the discharge end.

Into the outer end of casing 13 is'screwed a plug 21, formed with a squared outer end 22 to facilitate removal and having a thimble shaped nipple 23 projecting through chamber 16 and into opening 19 and ending where casing 15 begins. The plug is formed with a centrally-disposed passage 24, extending from end to end of the plug, screw- 'the side of opening 19, and where it projects substantially IOO into opening 19, is of less width than said opening, a passage from chamber 16 to casing 15 thus being left.

Steam or other suitable heated fluid is suppliedto the burner through entrances 11 and 24, and oil or other fuel is supplied to chamber'16 through entrance 18. The steam or other fluid comingthrough entrance 11 enters chamber 10, surrounds casing 15, and passes out through portion 7. Steam or other fluid entering through passage 24 is discharged at the end of nipple 23 into casing 15, where it induces How of fuel from chamber 16 through opening 19 and atomizes and mixes With the fuel, the mixture being carried by force ofwemission from the nipple through casing 15 and out of the burner. The interior of casing 15 gradually increasing in size from its receiving end to its discharge end, danger of back pressure of fuel is obvi, ated. The fuel is first heated in chamber 16 by contact with nipple 23, through which steam or other heated iuid passes, and the temperature of the mixture of steam or other fluid and fuel is further raised to the proper degree during its passage through easing 15, which is surrounded and heated by the steam or other heated iuid entering passage 11. At the discharge end of the burner this latter supply of steam or other fluid is converged across and mixes with the discharge of mixture from casing 15 by the converging surfaces 19 and 20.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, iis- 1. A burner comprising an outer casing having an opening therein :a member attached to said outer casing and includinga short portion forming a chamber having an opening thereto, an apertured transverse portion constituting a partition between said chamber and the interior of said outer casing, and an inner casing extending from said apertured portion and its aperture through said. outer easing, a space being left between said inner and outer casings, and a plug fitted. into said short portion and comprising a nipple projecting through said chamber and into the aperture in said apertured portion, a passage being formed through said plug.

2. A burner comprising an elongated outer casing 3 an enlarged outer casing connected therewith, forming a chamber, and having an opening into said chamber; a member attached to said enlarged casing, said member comprising a short portion forming a chamber having an opening thereto and joining said enlarged casing with which it is coincident in thickness and width, an apertured transverse portion forming a partition between said chambers, and an inner casing extending from said apertured portion and its aperture through said enlarged and elongated outer casings, a space being left between said inner and outer casings, and a plug fitted into said shortportion and comprising a nipple projecting through the chamber in said s wrt portion and into the aperture in said apertured portion, a passage being formed through said plug.

In testimony whereof I afiix my signature 1n presence of two witnesses.
