WALTER MORTON BR-OWVN, OF ALBANY, NE\V YORK.

STEAM-G EN ERATOR.

SPECIFICATION forming part of Letters Patent No. 409,664, dated August 27, 18189.

Application filed June 15, 1889, Serial No. 314,439- (No model.)

enee being had to the accompanying drawings,

and to the letters and figures of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a steam-boiler in which gas or oil as fuel can be burned economically and the heat or flame be applied internally and along the length of the boiler.

This invention is an improvement 011 that shown in my applications for patents now pending, numbered 285,862, filed September 20, 1888, and No. 290,960, filed November 15, 1888; and the improvement consists in placing the burners or oil-atomizers outside of the boiler and projecting the flame into the inside of the inner shell and practically along its length through openings made through both shells, thereby removing the bu rnerpipes and burners away from the intense heat inside the inner shell, instead of subjecting them to injury from the heat by placing them inside thereof.

In the drawings similar letters referto similar parts throughout the several views.

Figure 1 shows a horizontal sectional view of my boiler; and Fig. 2, a cross-section thereof, taken on line X X of Fig. 1.

' A shows the outside shell, which may be cylindrical or otherwise.

B shows the inside shell or cylinder running the whole length and inside of the outer shell A.

C shows a conduit laid over the shell B, and preferably welded thereto, the rear end of the conduit bein g in communication with the rear connection and in communication with the interior of the inner shell through openings 1; in the top of said inner shell.

D shows a water-tube inside the inner shell and in communication with the water in the boiler at both its ends to accelerate the circulation of the water.

E shows gas or oil burners located at the sides and outside the boiler, their tips or burners being entered through passageways J and practically along the whole length of the boiler.

F shows air passage-ways passing from the outside and bottom of the boiler into the interior of the inner shell to supply air for the support of combustion inside the inner shell.

II shows a bed upon which the boiler may rest and by which the burners may be supported.

J are openings through the sides of the boilers through which the gas or oil burners may be entered, said openings extending practically the whole length of the boiler.

The darts indicate the course of the prcducts of combustion.

It is evident from the drawings that the passage-ways J may be omitted and the burners or oil-atomizers be placed under the boiler and introduced through the air-intake passage-ways F, in which case it would be only necessary to make the passage-ways F of greater diameter, so that both the burners and sufficient atmosphere can pass through these air-intake openings. It is also evident that the burners or atomizers need not actually enter the passage-ways, as their tips may be located outside of said passage-ways and near thereto and the flame or atomized oil be projected through said passageways. The loca tion of said passageways is immaterial. The water-tube D may be omitted, if desired, and in some forms of boilers-like locomotive boilers, where the service required is very irregular, sometimes requiring the greatest intensity of heat and at other times the minimum intensity-it would be preferable to omit this tube D and partly fill the inside shell 13 with fire-brick so disposed as not to stop the intake of the air through the air passageways and to protect the atomized oil or flame among this brick, as is sometimes done in oilburning furnaces; but with the arrangement of the burners shown in Fig. 2, when the flames are shot together, refractory material may be dispensed with.

The operation of my invention is as follows: Oil or gas being forced out at the burners E and ignited, the flame is projected into the interior of the inner shell and practically along its entire length. The air to support combustion enters through openings F, and some is drawn in alongside of the burners E through the openings J, and active combustion is thereby maintained along the whole length and interior of the boiler, instead of at but one end of it, as is at present the universal practice. The products of combustion pass immediately off through the openings b and conduit G into the back connection, thence through the boiler-tubes to the front connection, and thence up the smoke-stack, whereby is provided a cylindrical boiler havin g a cylindrical fire-box or combustion-chamber practically as long as the boiler and running its whole length, in which active comb ustion is maintained from end to end, practically, by the use of gas or oil as fuel, the burners or oil-atomizers being located outside of the boiler, Where the heat will not damage them.

I make no claim upon a boiler having two shells, the smaller located inside the larger, and having passage-ways leading from the outside of the boiler into the interior of the inner shell, as such a form of boiler is not new. v

I make no claim upon projecting oil or gas through the sides of fire-boxessuch as are universally used on locomotives-as such a manner of injecting oil into such rectangular boxes is not new; but,

Having fully explained my invention, so that any one skilled in the art to which it appertains may make and use the same, what I do claim, and seek to secure by Letters Patent, is-

1. A longitudinal steamboiler having an internal combustion-chamber running practically the Whole length of the boiler and having passageways leading from the outside of said boiler to the interior of the internal combllS'DIOH-Clltlllbl and along its length, in combination with burners for the combustion of gas or oil arranged outside of said boiler and along its length, said burner being introduced through said passage-ways leading into the interior of said combustion-chamber, in order that the gas or oil flame may be projected into said combustion-chamber and along its length, substantially as described.

2. A longitudinal steam-boiler having an internal combustion-chamber 'running practically the length of the boiler and having passage-ways leading from the outside of said boiler to the interior of the internal combustion-chamber and along its length, and having other passage-ways leading from the i11- terior of the combustion-chamber along its length through the steam and water space to the outside of said steam and water space that the products of combustion may escape, in combination with burners for the combustion of gas or oil arranged outside of said boiler and along'its length, said burners being introduced through said passage-ways leading into the interior of said combustion-chamber, in order that the gas or oil flame may be projected into said combustion-chamber and along its length, substantially as described.

3. A longitudinal steam-boiler having an internal combustion-chamber running practically the whole length of the boiler and having, passage-ways leading from the outside of said boiler to the interior of the internal combustion-chamber and along its length, in combination with burners for the combustion of gas or oil arranged outside of said boiler and along its length, said burners being in proximity to said passage-ways, in order that the gas or oil flame may be projected through said passage-ways into said combustion-chamber and along its length, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

It ishereby certified that in Letters PatentNo, 409,664, granted August 27, 1889, upon the application of Walter Morton Brown, of Albany, New York, for an improvement in Steam Generators, errors appear in the printed specification requiring the following correction, viz: In line 97, page 1, the Word protect, should read project,

and in line 49, page 2, the Word burner should read burners; and that the Letters Patent should be read with these corrections therein that the same may conform to the record of the case in Patent Office.

Signed, countersigned, and sealed this 1st da y of October, A. D. 1889.
