HYDROCARB ON-B URNER.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed November 13,1907. Serial No. 402,009.

To all 'whom it may concern:

Be it known that I, WILLIAM SCRIMGEOUR, a citizen of the United States, residing at Portsmouth, in the county of Norfolk and IState of Virginia, have invented certain new and useful Improvements in Hydrocarbon- Burners, of which the following is a specification.

This invention relates to hydrocarbon burners, and the object of the invention is to provide a burner capable of producing an intense fiume, while using comparatively low air-pressures. Y

In the preferred embodiment of the invention means are provided for controlling the flow of the portion of the air which is utilized for atomizing and distributing the hydrocarbon, thereby permitting a close regulation and control of the flame.

For a full understanding of the invention reference is made to the accompanying drawing wherein Figure 1 is a central vertical section of a preferred form of burner; Fig. 2 is a plan view of the saine; Fig. 3 is a transverse section on line 3 3 of Fig. 1 viewed in a forward direction; and Fig. ft is a transverse section on line 4-4, of Fig. 1 viewed in a rearward direction.

In the drawings, 1 represents a burner cas-- ing having a flame-aperture 2, the portion of the casing adjacent the aperture being preferably thickened as shown at 4 is the air-inlet end ofthe burner, provided with the usual air-controlling means (not shown). I/Vithin the casing 1 and extending transversely across the same is a bridge 5, cast integral with thecasing and subdivi ding the same for the greater portion of its length into upper and lower passages designated Gand 7 respectively. The bridge 5 is preferably wedge-shaped, and the thicker or forward end 8 terminates at a point approximately opposite the flame-aperture 2 and somewhat in the rear of the same.

The top of the casing 1 is extended upwardly as indicated at 9, the sides of the enlargement converging upwardly as indicated in Fig. 4;. Within the space so provided is a wedge-shaped bridge member 10, integral with the burner casing, and serving to further subdivide the upper passage 6 into upper and lower passages 11, 12. Within the wedge-shaped member 10 is a transverse oilpassage 13, closed at one end by a removable plug 14k and fitted at the other end with a i,

serve to discharge the oil into the burner casing and toward the upper and forward portions of the walls of the enlargement 9 thereof. The apertures 16 will vary in size and form in accordance with the character of the oil and the pressure under which it is supplied. Above the oil-ports 16 and affording access thereto for cleaning I prefer to provide a removable plug 17. As shown the lower face of this plug is formed with curved surfaces 18, 19 intersecting in a transverse edge or rib 20, the curved face 19 serving to direct the air downwardly and into close proximity to the ports 16. The forward portion of the enlargement 9 termi nates in a downwardly projecting edge or rib 21, the conformation of parts being such that the coml'ningled air and oil or oil-vapor are thoroughly mixed, and are directed downwardly against the heated bridge 5. From this point they are conveyed by the air blast through the passage 6 to the forward end of the burner, are there commingled with th air which has passed beneath the bridge, and are discharged through the flame-aperture 2.

It is desirable, although not in all cases necessary, to provide means for controlling the quantity of air passing above the wedgemember 10 and into proximity to the oilports 1.6. For this purpose I prefer to providea plug-valve 22, rotatably mounted in the casing above the wedge-member 10, and having an air-port 23; this plug-valve serves to control the uppermost air-passage, or to entirely close the same, and is in operation regulated in accordance with the oil supply through the ports 16, to secure a thorough distribution or atomizing of the oil.

By constructing the transverse member 10 in the form of a wedge presenting its thin edge to the air-inlet and having its lower face converging toward the adjacent surface of the bridge 5, I am enabled to secure important advantages in the more complete and rapid atomization of liquid fuels. The form of air-passage 11 is such as to direct the air across the mouth of the oil-port 16 and in large part to atomize the oil asit issues therefrom. The convergence of the passage 12 in the direction of the air current results in a gradual increase in the velocity of the air moving therethrough, and insures its delivery at maximum velocity at a point where it commingles with the atomized oil; at the same time any oil iowlng in a film down the anterior ace or" the member l0 is intercepted and vaporized by the air at the moment of emergence at relatively high velocity from the end of the passage 12.

he rearwardly tapering construction of the bridge S results in a similar progressive increase in the velocity of the air moving through the passage 7 and increases the effectiveness of the mixing action at its delivery end.

I claim:

l. A hydrocarbon burner comprising a casing having an air-inlet and a vapor-outlet, and a wedge-shaped member extending across the casing and having its ledge directed toward the air-inlet, said wedgeshaped member provided with an oil-port.

2. A hydrocarbon burner comprising a casing having an air-inlet and a vapor-outlet, a wedge-shaped member extending across the casing and having its edge directed toward the air-inlet, said wedgeshaped member provided with an oil-port, and a valve for controlling the air-passage above said member.

3. A hydrocarbon burner comprising a casing having an air-inlet and a vapor-outlet, a wedge-shaped member extending across the casing and having its edge directed toward the air-inlet, said wedgeshaped member provided with an oil-port, and a transverse bridge below said wedgemember.

4. A hydrocarbon burner comprising a casing having an air-inlet and a vapor-outlet, a wedge-shaped member extending across the casing and having its edge directed toward the air-inlet, said wedgeshaped member provided with an oil-port, and a transverse bridge below said wedgemember and forming therewith an air-passage converging in the direction of the aircurrent.

5. A hydrocarbon burner comprising a casing having an air-inlet and a vapor-outlet, a wedgeshaped member extending across the casing and having its edge directed toward the air-inlet, said wedgeshaped member provided with an oil-port, and a rearwardly tapering transverse bridge below said wedge-member and forming therewith and with the bottom of the casing air-passages converging in the direction of the air-current.

6. Av hydrocarbon burner comprising a casing having an air-inlet and a name-aperture at opposite ends, a substantially horizontal transverse bridge or partition disposed between said air-inlet and Haine-aperture and terminating adjacent said flameaperture, said bridge tapering toward said air-inlet, and means for introducing oil above said bridge.

7. A hydrocarbon burner comprising a casing having an air-inlet and a flame-aperture at opposite ends, a transverse bridge or partition disposed between said air-inlet and name-aperture and terminating adjacent said name-aperture, and a wedge-member disposed above said bridge, said wedgemember having a transverse oil-passage and an upwardly extending oil-port communieating therewith.

8. A hydrocarbon burner comprising a casing having an air-inlet and a name-aperture at opposite ends, a transverse bridge or partition disposed between said air-inlet and flame-aperture and terminating adjacent said flame-aperture, a wedge-member disposed above said bridge, said wedge-member having a transverse oil-passage and an upwardly extending oil-port communicating therewith, and controlling` means for the air disposed above said wedge-member.

In testimony whereof, I afix my signature in presence of two witnesses.
