To all whom it may concern:
Be it known that I, ALBERT GERMAN, a citizen of the United States of America, residing at Steelton, Dauphin county, Pennsylvania, have invented certain new and useful Improvements in Oil-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention,
- such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
This invention relates to improvements in oil burners, and has for its object to provide a simple and strong construction wherein oil and air may be combined under pressure for the purpose of forming the flame into a sheet, which is especially effective for igniting 'a mixed charge of ore and fuel in sintering pans, but said burner may also be used for other purposes wherein a sheet of flame is desirable.
The invention consists in projecting under substantially equal pressures from opposite directions a stream of oil and a stream of air onto deflecting surfaces mounted within a shell or casing, and designed to convert the streams into thin sheets, whereby the oil and air may be more readily combined and converted into a combustible mixture, which issues from the periphery of the shell in a horizontal sheet or series of jets.
In the accompanyin drawingFigure 1 is a vertical section 0 one form of burner embodying my invention corresponding to the line 22, Fig. 2. Fig. 2 is a top plan view of the bottom plate. Fig. 3 is a vertical section of a modified form of burner. Fig. 4: is a bottom view of the deflecting plate shown in Fig. 3. Fig. 5 is a vertical section of another form of burner taken on line 2-5 of the plate shown in Fig. 2. detail view, partly in section, of a modified form of oil feed-pipe.
The burner shell consists of a circular bottom plate a and a hollow top 12 secured together by bolts 0 passing through holes in the outer edge thereof. The interior of the top is made to provide a hollow space, preferably conical, and has a central screwthreaded aperture through which the oil feed pipe (Z projects, said pipe being screw- Fig. 6 is a threaded to engage the threads of the aperture and the threads of a lock-nut e by which the pipe is securely locked in place.
T bottom plate has a central screwthreaded :(perture a into which is screwed an air fe .-pipe 7?. The plate a shown in Figs. 1 and 2 has formed in its top face a series of radial grooves or channels a. whichextend from the Central aperture 11 to the periphery of the plate,
Mounted on the top face of the plate a in the center thereof is a deflecting member, shown as a hollow cone g, which is held securely in place on the p ate by the feed pipe d the lower end of which rests on the'cone below the apex thereof and is closed thereby. As shown the facepf the cone 9 is separated from the interior wall of the top 6 providing an annular chamber or space b. around the part of the cone which receives the oil from the feed pipe d. With the class of oil I have used I have had good results by having the space it gradually diminish toward the periphery of the shell. With otherclasses of oil, tar, etc,, it may be necessary to modify the form of the space and vary the convexity of the deflector.
In the specific structure illustrative of my invention the face of the-cone 9 lies at a less angle to the face of plate a than that at which the interior wall of the top 5 lies, so that an annular chamber 72. is formed around the oil feed pipe 03 which gradually converges toward the periphery of the shell. The pipe d communicates with the chamber through a seriesof apertures (if formedin the pipe above its lower end.
Oil being supplied to the pipe (I under pressure, it flows through said apertures onto the top of the cone. The air is introduced under substantially the same pressure, through the pipe f under the cone, and is deflected by the latter downward onto the plate a. and escapes from under the cone through the grooves or channels (1, and combines with the oil at the lower edge of the cone, forming a readily combustible mixture which is forced beyond the periphery of the shell, and when lighted will burn inthe form of horizontal jets.
In the form shown in Figs. 3 and 4, means are provided for supplying the oil and air mixture in a thin sheet instead of a plurality of jets. This is accomplished by forming the top of the bottom late a with a smooth surface and raising t e flange of the top 1) above the plate by resting it on for the-air is provided between the pipe 7 and the periphery of the shell.
Fig. 5' illustrates a modified form of oil feed, wherein the oil flows from the bottom of the pipe d which is raised above the cone. To secure an accurate centering of the deflecting cone the pipe d may first be screwed down onto said cone, and then the set screws 9' mounted in the top 6 are screwed down onto the cone to hold it in place, whereuponthe pipe d is raised into operative position. It is possible b this means to readily regulate the flow 01 oil through the pipe. The bottom plate in this form is the same as that shown in Fig. 1, but the bottom plate and deflecting cone shown in. Fig. 3 may be substituted therefor.
Instead of the aperture h shown in Figs. 1 and 3 the lower end of the feed pipe (I may be provided with aplurality of notches (Z as shownin Fig. 6. In Figs. 1, 3 and 6 the pipe (Z holds the conical deflecting member in position.
I claim 1'. In an oil burner, a stationary shell consisting of a bottom plate, a hollow top arranged thereon and forming therewith a central chamber having a narrow peripheral radially directed aperture, an air supply pipe entering through an aperture in said bottom plate, an oil supply pipe projecting through a central aperture in the top, and a cone-shaped deflecting member having its apex centered in the end of the oil supply pipe and its periphery in the plane of said aperture.
2. In an oil burner, a shell consisting of a bottom plate, a hollow top arranged thereon and forming therewitha central chamber having a peripheral aperture, an air supply pipe entering through an aperture in said bottom plate, an 011 supply pipe having apertures near itsend and projecting through a central aperture in the top, and a hollow cone-shaped member having its noeasra end seated in the discharge end of the oil supply pipe.
3. 11 oil burner comprising a circular bottom plate having a plurality of radial grooves formed in its upper face, a hollow member having a flange resting on the top face of the plate, an oil supply pipe having discharge apertures near its end and projecting through a central aperture in the top of the hollow member, a hollow conical member mounted on the top face of the bottom plate and having its apex projecting into the oil pipe, and an air supply pipe entering an aperture in the bottom plate.
4. An oil burner comprising a circular bottom plate having a central aperture and a plurality of radial grooves in its top face extending from said aperture to the periphery of the plate, a hollow member having a flange seated on the bottom plate and having a central aperture, an oil supply pipe having discharge apertures near its end and projecting through the aperture in the hollow member, a hollow conical deflecting member mounted on the top face of the plate and having the apex projecting into and closing the end of said pipe, and an air pipe mounted in the aperture of the bottom plate.
5. In combination, a casing comprising two members, one of which is a flat plate and the other member being conical and having a flange at its base, a narrow radially directed discharge passage between the plate and easing, supply pipes centrally secured in the members, a conical deflector, one of said pipes engaging the apex of the deflector and holding it against the flat plate and centrally of the conical. member, the edge of said deflector lying in the plane of said dis charge passage.
6. The combination with a casing comprising a flat member and a' frusto-conical member; of a supply pipe for oil connected to one member and a supply pipe for air connected to the other member, and a conical deflecting member held centered against the flat member by the supply pipe of the other member.
In testimony that I claim the foregoing asmy invention, I have signed my name in presence of two subscribing witnesses.
