Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed July 18, 1918. Serial No. 245,545.

To all whom it may concern:

Be it known that 1, WILLIAM C. Lone, citizen of the United States of America, residing at Gordon, in the county of Butler and State of Kansas, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an oil burner and has for its principal objectthe production of a burner which is so arranged as to spread the flame for constituting a large heating area when the device is in operation.

Another object of this invention is the production of an oil burner wherein a bell is mounted upon the casing and arranged so as to spread the flame issuing from the casing.

A still further object of this invention is the production of an oil burner which has an inner tube extending into the casing for injecting oil thereinto, while another tube is connected to one side of the casing for injecting steam thereinto so as to allow the oil and steam to mix which will produce a combustible gas and supported by the injection of air into the inner end of the casing.

With these and other objects in view this invention consists in general of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings:

Figure 1 is a top plan view of burner.

Fig. 2 is a side elevation of the oil burner.

Fig. 3 is a longitudinal section through the oil burner.

Fig. 4c is an enlarged section taken on the line a l, of Fig. 2.

Fig. 5 is a transverse section through the oil burner taken on the line 5-5, of Fig. 2, looking in the direction of the arrows.

Fig. 6 is a detail perspective view of the oil tube.

Referring to the accompanying drawings by numerals, it will be seen that the casing 1 is elongated and is preferably cylindrical in cross section as shown in Fig. 5, although of course it is obvious that the same may be of any desired shape without departing from the spirit of the invention. This casing 1 is internally'threaded at its forward to receive the exthe oil ternally-threaded collar 3 of the bell 4. This bell 4 is flared and is carried at the forward end of the casing 1 so as to constitute a flame spreader for the oil burner when the same is in use.

The cap 5 is threaded upon the inner end of the casing 1, as shown at 6, and this cap 5 is provided with an integral, elongated collar 7 as shown clearly in Figs. 3 and 4c. This collar 7 is internally threaded as indicated at 8 and projects for distances beyond the inner and outer surfaces of the cap 5. It will, therefore, be seen that by positioning the cap 5 upon the inner end of the casing 1, this inner end will be closed although the forward end of the casing will be open.

The inner oil tube 9 has its threaded end 10 screwed into engagement with the collar 7 and this oil tube 9 projects for a considerable distance within the casing 1 as shown in Fig. 3. It will be noted, however, that this inner oil tube 9 is comparatively small so as topermit free passage space along the side thereof, while the free end of this inner oil tube 9 terminates at a distance from the bell l of the oil burner. The short pipe 11 is threaded into engagement with the outer end of the collar 7 and this short pipe 11 is adapted to receive oil from any suitable source of supply for conveying this oil to, the tube 9, and thence permitting the oil to be discharged into the easing 1 adjacent the forward end thereof.

The casing 1 is provided with an annular flange 12 formed upon one side thereof and communicating with the interior of the easing, as shown in Fig. 4. This flange 12 is internally threaded as shown at 13 so as to permit the" supply pipe 14 to be threaded into engagement therewith. This supply pipe 14: is adapted to be connected to any suitable source of supply for conveying steam into the casing at a point adjacent the inner end thereof and in alinement with'the oil tube 9 adjacent its inner end. It will also be noted that the casing 1 is provided with a thimble 15 having an opening v16 formed therein. and communicating with the interior of the casing. This thimble 15 is formed upon the casing at a point adjacent its inner end and contiguous to'the cap 5 when the cap is mounted upon the inner end of the casing 1.

When this oil burner is in use it is first assembled by screwing the bell 4 upon the forward end of the casing 1 and the cap upon the inner end thereof. At the time the cap is screwed upon the inner end of the casing it is carrying the oil tube-9 as hereinbefore specified, and then the short pipe 11 is screwed into engagement with the cap, after which the supply pipe 14 is screwed into engagement with the flange 12. The oil injected into the casing through the pipe 11 and tube 9 will be discharged at the forward end of the pipe into the casing at its forward end. The steam injected into the casing by being admitted through the supply pipe 14 will strike upon the tube 9 adj acent its inner end and will aid in the heating of this tube for the vaporizing of the oil as the same passes from the forward end thereof. It will also be noted that the force of the steam and oil within the casing by being discharged at the forward end thereof will constitute a suction at the inner end of the casing, thereby causing air to be drawn through the opening 16 into the casing, thus causing the mixture of the vaporized oil, steam and air to produce a highly combustible substance which is ignited at the forward end of the casing. As the flame issues from the forward end of the casing, it will be directed by the flared bell 4 over an enlarged area which is to be heated, while the air openings 17 formed in the bell are arranged adjacent the sleeve 3 of this bell thereby causing the suction produced by the direction of the flame to be relieved by the passing of air in behind the flame adjacent the outer end of the casing.

It is, of course, obvious that this oil burner may be used in quite a-number of ways, such, for instance, as in connection with a boiler by placing the burner in a fire box, or when drilling wells, or for various other purpose, for under all conditions it will produce an enlarged flame having intensified heat which because of the arrangement of the intake portions will cause the perfect combustion of the different elements injected into the casing. I

It is not intended to limit the construction of this'device to the specific form herein shown, for it is intended to modify the structure in accordancewith the scope of the invention as claimed.

What is claimed is V 1. In an oil burner of the class described, the combination of a casing having an internally-threaded forward end, means for in- Gopies of this patent may be obtained for five cents each, by addressing the Commissioner jecting a combustible substance into said casing, a comparatively large flared bell having a reduced externally-threaded sleeve formed thereon, said sleeve screwed into said casing at its forward end, and said bell extending beyond the outer face of said casing and having a formed adjacent to but beyond said sleeve and beyond said casing, whereby the flame passing from said casing will be spread by said bell, while said openings will relieve the vacuum within the bell adjacent said sleeve.

2. In an oil burner of the class described, the combination of a casing, a cap threaded upon the inner end of said casing, said cap having an internally-threaded collar projecting forwardly and rearwardly its side faces, an inner oil tube threaded at its inner end into the forwardly extending end of said collar, a supply pipe screwed into the said rearwardly extending portion of said collar, means for injecting air and steam into said casing, and means on the outer end of the casing for spreading the flame.

3. In'an oil burner of the class described, the combination of a casing of the same diameter throughout its length, a cap on the inner end of said casing and provided with a rearwardly extending and a forwardly extending internally-threaded collar, an oil plurality of air openings pipe threaded into said forwardly extending portion of the collar, a pipe threaded into the rearwardly extending portion of the collar, a steam pipe connected to the casing in alinement with and opening at its inner end directly upon the side of said oil pipe whereby steam issuing from said steam pipe will be discharged directly upon said oil pipe, a thimble formed upon one side of said casing and opening directly upon the side of said oil pipe, and an enlarged bell having a reduced threaded sleeve, the sleeve threaded into the outer end of said casing and the bell of greater diameter than the casing and extending a considerable distance beyond the outer face of the same, said bell having a plurality of air openings formed outside of the collar and beyond the outer end of the casing, whereby the flame passing from said casing will be spread by said bell, while said openings will relieve the vacuum within the bell by allowing air to enter directly the bell from the outer atmosphere.

In testimony whereof I hereunto aflix my signature.
