OIL BURNER Filed DGO. 18, 1926 /C-I'G, 4.

Patented .l an. 1G, 1933 .ares are JAMES C. LYLE AND RICHMOND W. MESSMORE, OF DAYTONA BEACH, FLORIDA OIL BURNER Application filed December 18, 1926.

The invention relates to oil burners f or furnaces and the like, and has for its principal objects to provide a burner the parts of which are simple and economical to construct, assemble and install; and which will quickly and thoroughly volatilize the -oil so that the vapor is practically dry and m the best state for combustion when it reaches the place of burning. Also the parts are prefer- 0 ably readily separable for cleaning and the removal of any possible obstruction to the desired movement of the oil, vapor and air to enter into the combustion.

lith such objects in view, as well as other advantages which may be incident to the use of the improvements, the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the understanding that the several necessary elements constituting the same may be varied in proportions and arrangement without departing from the nature and scope of the invention.

In order to make the invention more clearly understood there are shown in the accompanying dra-wing means for carrying the same into practical eifect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose of explanation, have been made the subject of illustration.

In the said drawing Fig. 1 is a vertical sectional view of a n burner embodying my invention, installed on the lower part of a furnace.

Fig. 2 is a horizontal section of the same on line 2 2 of Fig. 1.

Fig. 3 is a front view, partly in section, of the support and air intake of the burner.

Fig. Ll is a similar view of the generator.

Fig. 5 is a similar view of the baflle and vapor conductor.

Fig. 6 is a similar view of the removable top of the generator.

ln said drawing, 1 indicates a port-ion of the base of a furnace, which may be of brickwork, and which is formed with a vertical air supply passage Q. Above this passage is :n mounted the support and air intake 8 of the burner, formed with a base Llc which rests on Serial No. 155,684.

the brickwork and with an outwardly flaring upper part 5 which is arranged to deliver the mixture in an upward and slightly outward direction so as to cause the products of Vcombustion to impinge on or pass nearby the out r wall of the generator. rl`he support is further formed with lugs 6 on which removably rest legs 7 which carry the burner spaced above the top edge of the support.

The generator 8 is formed at its bottom part with an oil-receiving receptacle 9 of annular form, bounded on its inner side by an upstanding flange 10. The ange part 10 is continued down below the bottom of the burner and curved upwardly to form a lighting cup 11 in which a small charge of oil may be contained and lighted by hand for starting the burner. The legs 7 support vthe bottom of the cup 11, to which they may be attached. "0

The generator is covered by a removable cap 12.

.Inserted down into the ilange 10 and resting on lugs 10 is a baille 18 the top of which extends outward to near the outer wall of the generator so as to force the moist vapors .arising from the oil into contact with the heated wall of the generator so as to further vaporize and thoroughly dry the fuel constituent. Said vapor passes thence down '80 through the tubular middle portion 14 of the battle.

Oil is supplied to the generator by a pipe 15 which extends upward and sidewise through apertures in the tube 14 and flange 10, so as o to gradually deliver oil in the necessary quantity to the generator.

The plane of combustion or grate line is indicated at a?, fc, and at this plane the descending vapor meets the rising air supplied through the intake 3. Here the constituents of combustion are thoroughly mingled and, havin been ignited, burn in an upwardly directed flame which envelopes the generator.

16 is .a non-backfire screen mounted within the tubular part 14 of the baille to prevent any passing of fire up into the generator.

The oil pipe is removable from its engagement with the battle. and generator, by removal of the top, and then the battle may be sec removed from the generator and the generator may be removed from the intake, and all parts cleaned as may be required. rlhe parts can be reassembled with equal readiness.

The cup ll and the air intake 3 form the upper and lower lips of the combustion aperture extending around the burner in a hori- Zontal circular direction.

The proper level of the oil in the receptacle 9 can be maintained by a float in a known manner.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

lVhat is claimed is l. An oil burner for furnaces and the like having a tubular air intake, and above the saine a generator having an annular oil receptacle, and forming with said intake the upper and lower lips of an annular combustion aperture which extends around the burner, and means for causing the vaporized oil to pass outward against the wall of the generator and thence down against the rising air, the mixture thence passing through said combustion aperture.

2. In an oil burner the combination of a support and air intake, a vapor generator spaced above the same to form an annular combustion aperture, an oil pipe delivering into said generator, a vapor baffle in sai-d generator extending` outward towards the wall of the generator to cause the vapor to pass against the heated wall of the generator and having a tubular vapor-conducting neck extending downward relative to the generator to deliver vapor against the air rising through said intake, at a mixing point near said combustion aperture.

3. In an oil burner the combination of asupport and air intake, a vapor generator spaced above the same to form an annular combustion aperture and having an annular oil receptacle, an oil pipe delivering into said receptacle, a vapor battle in said generator extending outward towards the wall of the generator to cause the vapor to pass against the heated wall of the generator and having a tubular vapor-conducting neck extending downward relative to the generator to deliver vapor against the air rising through said intake, at a mixing point near said coinbustion aperture.

Il. ln an oil burner the combination of a support and air intake, a vapor generator spaced above the saine to form an annular combustion aperture, an oil pipe delivering into said generator, a vapor baffle in said generator extending outward towards the wall of the generator to cause the vapor to pass against the heated wall of the generator and having a tubular vapor-conducting neck extending downward relative to the generar tor to deliver vapor against the air rising through said intake, at a mixing point near said combustion aperture, and having a cup the upper lip of the combustion aperture.

5. ln an oil burner the combination of a support and air intake, a vapor generator removably resting on and spaced above the same to forni an annular combustion aperture, an oil pipe delivering into -said generator, a vapor baffle in said generator extending outward towards the wall of the generator to cause the vapor to pass against trie heated wall of the generator and having a tubular vapor-conducting neck extending downward relative to the generator to deliver vapor against the air rising through said intake, at a mixing point near said com bnstion aperture.

6. ln an oil burner the combination of a support and air intake, a vapor generator spaced above the saine to forni an annular combustion aperture, an oil pipe delivering into said generator, a vapor baffle in said generator extending outward towards the wall of the generator to cause the vapor to pass against the heated wall of the generator and having a tubular vapor-conducting neck extending downward relative to and removably resting on the generator to deliver va por against the air rising through said intake, at a mixing point near said combustion aperture.

7. The combination of the generator having an upstanding tubular flange the bottom part of which forms a cup under the generator, and a baille in the generator having a tubular part for conducting vapor down from the generator and iitting within said flange of the generator.

In testimony whereof we affix our signatures.
