OIL-BURNER.

Be it known that I, HIRAM C. RUGGLES, a citizen of the United States, residing at Phoenix, in the county of Maricopa and thel State ofArizona, have ninvented new and useful Improvements ein' Oil-Burners, -ofI which the following isa specification.

.This invention relates to improvements in hydro-carbon burners'and particularly to that class of burners in which steam or other pressure producing means is employed, and carrying the oil to the burner and flame.'

It is an object of the invention to pro'- vide a 'burner in- Which the hydro-carbon substance will be drawn from nozzles which lthoroughly distribute the same about the jet of steam, air or other material.,

v.It is also an object of the invention tol provide a burnerA having a distributing nozzle device for spreading the oil or hydrocarbon .material around the jet openings through which the pressure means for distributing the same must pass, -whereby an even atomizing of the material will be"ac'' complished. l

Itis a` further object of the invention to provide a hydro-carbon burner with an oil steam vspraying pipe incl'oslng a portion of the oil pipe seas to-thoroughly warm the oil before. it is to be sprayed or atomized, the couplings in the piping being mounted loosely one within the other to allow for expansion and contraction in the metal. l

It is a further object of the invention to vprovide an -oil burner with means for supvplying'steam thereto, the said steam pipe having a removablestrainer mounted in the piping in such a manner that it may be withdrawn at any time without disjointing the piping for cleansing the said strainer.

The details and features of the invention Will now be more particularly described, reference being had which ,v

5 indicates an oil supply pipe, and :6 a steam supply pipe. The burner isso constructed that the hydro-carbon oils employed are preferably fed to the burner from an oil pipe which extends' to the atomizing spraying or atomiz# ing theoil is usually steam, compressed air or other `pressure roducing means, but the burner is admirabFy adaptedfor theuse of steam, since'the heat thereof can be utilized for warming the oil before it reaches the atomizing portion ofthe burner.

The piping which carries the ,pressure and atomizing agent will be hereinafter termed the steam pipe, and adjacent to the oil pipe 5, the said steam pipe is preferably provided with an elbow 7 having an enlargedchamber 8 formed therein, the said elbow having Patented May 6, 1913.

an open end portion 9 which is adapted to Y receive and be closed by the plug'lO. 'The said plug 1Q carries a perforated cylindrical member forming a strainer 11, and is adapted to insert or'remove the same when the plug is put in place or taken from the said elbow.- The inner end of the said strainer 1l is preferably open and approaches so i i closely to the reduced portion of the elbow at 12 that the steam must pass through the perforations of the strainer in order to pass onwardly to and through the other portions of the burner. From the strainer the steam passes to a coupling 13 which is adapted to pipe as clearly shown in Fig. 2. The said coupling has a steam chamf ber 14 formed therein, and is provided with an outlet 15 which. is of larger diameter than the oil pipe so as to distribute the steam around the said pipe as it passes onwardly toward the atomlzing portion ofthis coupling to the the burner. From atomizing portion of the burner the oil pipe passes inside the steam pipe, the steam pipe eingenlarged as indicated at 16.

The b urner is provided withan upright portion made up of the-inner oil pipe andI the outer enlarged steam pipe as indicated .at 17 and 18 respectively 1n Fig. 1. The

-are preferably to properly reach the fire boX or combustion portions of the burner heretofore described arranged in horizontal form chamber'in ed, and the which the burner is to bemounthorizontal portion of the burner carrles at its inner end the upright or ver-A and its connections within the said The upper end Vof the inner pipe .17 tering ticalportion for holding the atomizing end of the burner in proper position within such combustion chamber.

r1`he horizontal and upright portions of the burner are connected by inner and outerminates a short distance wit-hin the outer pipe 18'and carries an atomizer 21 which is screwed into the end of said pipe 17 and is formed with an enlarged circular c head having a series of nozzles 22 formed stood by reference to therein. The atomizer is so constructed that annular troughs23 extend around each of said nozzles 22. The edges of the nozzles are also ta ered and the said edges overhang. the space etween the pipes 17 and 18, so as to receive jthe steam or other atomizing agent from the said pipe 18.

The central bore of the 'atomizer 21 cuts into the inner edges o f the lannular troughs 23 as shown in F1gs.`1, 3 and 4 whereby outlets from the said central bore into the said troughs are a'orded lfor the oil. Resting upon the atomizer is an upper atomizer piece 24which is formed with openingsl 25 having Haring lower ends approximately fitting over the' said annular troughs 23 so as to receive the steam from the nozzles and the oil sucked upwardly by the same and atomized. The said upper atomizer piece 24 is provided'also with a centrally arranged screw 26, the enlargedl disk head 27 of which tits into the upper end of the bore in the atomizer 21. The adjustment of said screw not only assists in the assembling of the parts but controls the size ofthe open-A ings from the bore of the atomizer into the annular troughs 23 as will be clearly under- Fig; 3 of the-drawing.

An outer sleeve 28is adapted to fit over the peripheral'edges of the nozzle piece 24 and the atomizer 21 and the upper end of tlfe said pipe 18, so as to firmly hold the parts in pro er position. The'said nozzle piece' 424C is ormed with an annular shoulder 29 which is engaged by an inwardly proj ectmg annular flange carried by the sleeve 28 and the lower end of the said sleeve screws upon threads formed on the pipe 18.

The central portion of the upper atomizer piece 24 is also provided with an upwardly outer edge of the sleeve 28is oi'setv and screw projecting stud 31 which 'is formed with. a

reduced threaded portion32 adapted tofreceive a burner cafp plate 33 having a downwardly extending annular flange 34, the edge thereof being arrangedv opposite the upper edge of the cap ring 30 so as t form between the edges a discharge space for the atomizing vmaterial as itv escapesinto the flame. Portions of the lower edge of the cap plate 33 are arranged to extend lower than' other portions thereof as shown at 35. The depending portions 35. are preferably arranged on opposite sides of ,the said cap plate 33varying `the distribution of the ma- A Within' the ycap 33 a bale'plate 36 is arranged upon the'reduced portion 32 of the stud 31. -The nut 37 holds the said baille plate and space between the said parts, and the nozzle cap ring 30 below.

In the operation of the burner, t-he hydro- `fed in any desired manner pipe and the steam is admit-ted, passing through the strainer l1 whereby any scale or foreign substance from the cap plat'el33 in the boiler will be prevented from clogging the burner. The steamv then passes into the piping 16 and the elbow 20 to the piping 18 and will pass through the nozzles 22, atomizing and carrying with it' the oil which is supplied to the trcughs 23. The mixture will thence pass through the openings 25 and escape beneath the cap plate 33 where it will and the supply of oil in the troughs 23' being vevenly and thoroughly disposed around the steam jets, the atomizing voperation will be thorough and complete and the best result Wi l be obtained in supplying the iame with thoroughly atomized oil. It

will be observed] that although one pipe is withinl the other and that there may be va difl'erencein temperature in the pipe and the elbows, `that the said elbows will readily move Vwith respect to ,each other withoutv danger of breaking the parts or of interfering in any way with the steam supply.
