.To LLZZ whom, it may concern,.-

Be it known that I, ADOLH` BELER, acitizen of theUnited States, residing at Pittsburg,in`1

the county of Allegheny and State of Penn- 5 Sylvania, have 'invented a new and useful Gas-Burner, of which the following is a speciication.

My invention is an improved gasfburne'r adapted `for use for heating, cooking, and

1o other purposes and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

The object of my invention is to effect improvements in the construction of .the burner whereby air is thoroughly commingled with the gas"bet`ore the latter. reaocheslthe flame, so that the combustion of the gas is promoted, and the same is caused to burn `with `a blue flame. l 4

2o A further object of my invention is to provide means for regulating the intake of the air which is commingled with the gas, so that a due proportion of the air may become commingled with the gas to cause the flatterl to be entirely consumed. Y, i I y A further object of my invention is to ei'lect improvements inA the construction of the name-spreader.

In the accompanyingdrawingsyFigure l'is 3o a perspective view of a gas-burner embodying my improvements.- Fig2 is avertical.

central sectional View of the same. Fig. Sis a similar View .showingthe burner disposed in the heating-dome of an apparatus for heat-L ing a coil of water-pipes.

In theemloodiment of my inventionI pro vide a deiiector 1, which is here shown as of inverted conical form, having the downwardly-converging sides 2 and provided at its 40 upperside with a series of upstanding and outwardly-projecting lugs 3, whichare appro-` priately spaced apart, so that openings 4 are formed above the upper side of the deector between the said lugs. hence above the delector, is secured a flamespreader 5. The same is here shown as of annular form and V-shaped in cross-section, whereby the name-spreader is formed with downwardly-converging sides 6, between On the llatter, and- "l `which is formed a trough 7. In practice the said trough may be kept supplied `with water to -Vprevent the burnerfrom becoming overheated. The dame spreader is here shown as secured on the lugs 3 by means of screws 8; but, the same `may be secured on the lugs by any other suitable means, if preferred. `I further provide a casing 9. The upper portion of the' same is flared outwardly andV upwardly, as at 10, and the interior diameter thereof is slightly in excess of the exterior diameter of the upper portion of the deflector. The latter is disposed in the upper portion of thecasing 9, and a` `channel 1l is formed between Athe deilectorwyand the iiared upperportion of the casing, said channel communicating atits upper end with the outer air at a'point'below the `flame-spreader. The lowerportion of the casing 9 is here shown as of cylindrical formas at 12. VThe deiiector is disposed concentrically with reference to the casing. At thelower portion of the casing are aseries of air-inlet openings 13. A hood 14, which is herleshown as of truncated conical form, is provided with a cylindrical portion 15, which lits and is adapted to slide vertically on thelowercylindrical portion of the casing,

'the rsaid hood Abeing disposed over theJ'airM-in-` take openings 13. AAny suitable means maybe provided to secure the hood on the casing and permit of the vertical adjustment of the hood. I here show the cylindrical porti0n`1 of the hood provided with vertical slots16 and setscrews 17 in said slots and engaging threaded openings in the casing, said slots and setscrewsservingto secure the hood on the casing` and adapting the hood to be vertically adj usted,` so that itmay uncover the air-intake openings 13 to anydesired extent, and

`thus vary the effective areas of said openin gs,

and `hence regulate the quantity of air which Lpasses inwardly through said openings to the As here shown, the

interior of the casing. casing is secured to a supporting basefplate 18. Any suitable means may, however, Within the scope of my invention be employed to support the casing and the other parts of the burner. The said base-plate is adapted to be placed in the fre-box or dome of a stove,

furnace, or heater to serve as ahorizontal parted to the dame.

At the lower en'd of the casing 9 is an airintake funnel 19, which closes the lower end of said casing, is open on its lower side, and has an upwardly-extending cylindrical portion 20, which is disposed concentrically in the casing 9 and extends upwardly to within a suitable distance of the lower side of the deflector, the upper end of the cylindrical portion 2O of the intake-funnel being open. The said cylindrical portion ofthe air-intake funnel forms a primary mixing-chamber. A gas-supply nozzle or tip 2l is disposed concentrically in the lower portion of the air-intake funnel. The deflector 1 is here shown as supported and secured in position on the upper side of the casing by bolts 22, which connect the lugs 3 to the base-plate 18.

In the operation of my improved burner the gasis commingled with air in the primary mixing-chamber 2O and passes upwardly and is deliected outwardly. by the lower sides of the deflector 1. As the commingled air and gas escape from the primary mixing-chamber into the upperportion of the cylindrical part 12 of the casing 9 an additional quantity of air, drawn in through the air-intake openings 13, is supplied to the gas and commingled therewith, the space between the cylindrical portion 2O of the airintake funnel and the cylindrical portion 12 of the casing forming a secondary mixingchamber 23. The deliector causes the commingled air and gas to be spread laterally in a thin film as it passes upwardly through the channel 1l between the flared or inclined parallel portions of the deiiector and casing, hence effecting the complete blending and commingling of the air and gas in such manner as to form a highly-combustible mixture.

y pipes 26 is disposed above the burner, the

latter being utilized for heating the water in I the said coil. The flue or draft-pipe 27 ,which leads from the upper portion of the dome or {ire-box and through which the heated air passes, has its lower end surrounded by a deflector 28, which is located concentrically in the upper portion of the coil 26, is of cylindrical form, with its lower side closed audits from the, interior of the combustion chamber or dome. My improved burner may, however, -b`e used for other purposes and in other connections, and I do not therefore desire to limit myself in this particular. Neither do I desire to limit myself to the precise construction and combination of devices herein shown and described, as it is evident that modications may be made therein without departing from the spirit of my invention.

The channel 11 while ample to conduct the commingled gas and air to the base of the flame, owing to its linear extent and its diminished width, prevents the flame from reaching the mixing-chamber and causing imperfect combustion of the gas.

Having thus described my invention, I claim- 1. A bu-rner of the class described having a deector and a narrow channel leading therefrom to the ame, a primary mixer open to the outer air and having its inner end disposed opposite the deflector, means to discharge a jet of gas against the deIlector, through the primary mixer, whereby the commingled gas and air will be disposed in a thin-lm on the surface of the deector, and a secondary mixer, to admit air to the surface of the deiiector, at a point between the primary mixer and the intake of the channel, substantially as described.

2. In combination with an outer casing having a ared portion and a contracted tubular portion leading thereto, said tubular portion having means to admit air; a deflector in said casing, disposed proximate to the iared portion and across the contracted portion thereof, a narrow channel being thereby formed between them; an air-intake funnel disposed in the contracted portion of the casing, opposite the defiector and open at its outer end for the admission of air, and a gas tip or nozzle disposed to discharge a jet through the air-intake funnel and directly against the detlector, the air-intake funnel forming a primary mixing-chamber, the space between said funnel and the contracted tubular portion of the casing forming a secondary mixing-chamber, at the surface of the deflector, from which secondary mixingchamber the mixed gas and air pass through the narrow channel to the flame, substantially as described.

3. In combination with an outer casing having a flared portion and a contracted tubular portion leading thereto, said tubular portion having air-inlet openings and means to vary the effective area thereof; a deflector in said casing, disposed proximate to the iiared portion and across the contracted portion thereof, a narrow channel leading to the, flame being thereby formed between them; an air-intake funnel, disposed in the contracted portion of the casing, opposite the deector, and open at its outer end for the admission of air, and a gas tip or nozzle dis- IIO posed to discharge a jet through the air-inand adapted to contain Water, substantially 1o take funnel' and directly against the said deas described.
