OIL-BURNER.

Specification of Letters Patent.

Patented J an. 23, 11%17.

Application filed June 10, 1916. Serial No. 102,931.

To all whom it may concern:

Be it known that I, MAGY MAYNARD, a citizen of the United States, residing at Auburn, in the county of King'and State of lVashingt-on, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to an improvement in an atomizer or burner which is designed for use with heavy crude oils and which is primarily designed for use in connection with locomotives or other vehicles.

An object of the invention is to produce a burner having an oil passage or conduit and a steam passage or conduit which is arranged below the oil passage, the head or outlet end of the burner being round and the outlet ports for the steam, at the said mouth being disposed radially thereof whereby the steam will intermingle with the oil and be projected to the ends, sides and corners of the fire-box.

It is a still further object of the invention to construct an oil burner of this class which shall embody the desirable features of simplicity, cheapness and thorough efliciency.

Vfith the above and other objects in view the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling with the scope of the appended claims.

In the drawings: Figure l is a top plan view of a burner constructed in accordance with the present invention, Fig. 2 is an end view looking toward the head of the burner,

Fig. 3 is a vertical longitudinal sectional view approximately on the line 33 of Fig. 1, Fig. 4 is a horizontal sectional view approximately on the line l l of Fig. 8, and Fig. 5 is a similar sectional view approximately on the line 55 of Fig. 3.

The device may be constructed as a single element, and is thus illustrated in the drawings.

As shown in the drawings the burner in cludes a substantially rectangular body member 6 and has its end at its outlet portion rounded, as indicated by the numeral 7, and this rounded portion will hereinafter be referred to as the head of the burner. The body 6 is provided with a longitudinally extending oil conduit 8, the said conduit being of a substantially rectangular formation and being of a width almost equal J to the width of the body. The upper wall of the oil conduit 8, at the head thereof,

is rounded downwardly, as indicated by the numeral 9, so that the flow of oil through the said conduit will be downwardly directed. The numeral 10 designates the feed pipe for the oil conduit.

The steam conduit 11 is arranged below the oil conduit 8 and for the major portion of its length comprises a restricted passage 12 which at a suitable distance from the head of the burner is flared or beveled outwardly toward the sides of the body, as indicated by the numeral 13. The steam conduit proper terminates in a vertically disposed shoulder 14, and the head of the burner is provided with a plurality of radially disposed apertures 15 communicating with the steam conduit 11. It is to be noted that a great number of these apertures 15 is provided and that all of the said apertures are struck from the point or axis from which the are providing the rounded head 7 is struck, and by this means it will be noted that the flow of steam will be projected in a substantially fan-shaped form and the same contacting and mixing with oil projected through the oil conduit will atomize the said oil and project the same in a like fan-shaped form.

The numeral 16 designates the inlet pipe for the steam conduit 11.

The body 6 approximately in a line with the apertures 15 has its head, at its lower portion, projected to form a lip 17 the outer edge of the same being rounded and being struck from the axis of the head 7. This lip, at determined intervals, is provided with curved depressions providing angular walls 18 terminating in inner shoulders 19 and these portions of the device provide for the mixing of the oil and steam. The ends of the lip are formed with upwardly extending shoulders 20' 20 and the inner faces of these shoulders are beveled outwardly, as clearly illustrated by the drawings.

From the above description, taken in connection with the accompanying drawings, the simplicity of the device, as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description, it being understood that the burner may be used in connection with stationary plants and furnaces and that the atomizing may be from either steam or compressed am oil conduit and having its side walls at a distance from its head flared outwardly to the sides of the body and terminating in a straight shoulder, and the head being formed with restricted apertures communieating with the steam conduit and said apertures radiating from the axis of the head.

2. An oil burner comprising a substan tially rectangular body having a substantially rectangular oil conduit therein, an inlet pipe for the conduit, said body below the oil conduit having a restricted steam conduit, an inlet pipe for the steam conduit, the sides of the steam conduit adjacent to the outlet end of the burner being flared toward the sides of the said burner, said body having a plurality of radially disposed apertures communicating with the steam conduit, said body approximately in a line with the said apertures at the outlet end thereof being extended to provide a lip, said lip being formed with a plurality of rounded depressions, vertical extensions upon the sides of the lip, and the inner walls of the said extensions being beveled approximately in a line with the end apertures.

In testimony whereof I affix my signature.

MAGY MAYNARD.
