HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 7 37,999, dated September 1, 1903.

Application filed February 9, 1903 Serial No. 142,597. (No model.)

To whom it may concern:

Beit known that LGHAELEs CANNOM, a citizen of the Dominion of Canada, residing at London, in the Province of Ontario, Canada, have invented new and usefullmprovements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates generally to hydrocarbon-burners and specifically to that class employed in connection with domestic implements, such as steam-cookers or the like.

The object of the invention is in a ready, simple, thoroughlyfeasible, and practical manner to overcome danger of fires or explosions in the use of gasolene as a heating medium, to conserve its use, to obviate waste when the burner is not in use, to secure the maximum of heat units from the minimum of fuel consumed, and generally to improve, simplify, and render more efficient burners of this character.

The objects above stated are secured by dispensing with the employment of elevated tanks for containing the gasolene, the supplying of liquid gasolene to the burner-head, and the complete elimination of leakage and waste, with attendant danger of fire, as frequently results from improperly-fitting cock joints and valves. The results attained are secured in part by conveying liquid gasolene by capillary feed to a point adjacent to the burner-head and thence in vaporized form to the head, where it escapes in gaseous form and is ignited. Further advantageous results are secured by having the areas of the gas-supply openings communicating with the burner-head of so much greater area than the combined areas of the gas-escape openings as to create always a pressure within the burner-head, whichoperates to cause the gas to be expelled with considerable force, thereby producing a plurality of long-pointed flames, which by impinging the utensil containing the material to be heated will cause it rapidly to be brought to the desired degree of tempera- Furthermore, the relatively high pressure of the vapor or gas within the burner-head will operate to cause the gas-escape openings to remain free from any material that would operate to clog them, so that careful attention to the burner-head is rendered practically unnecessary.

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a burner for hydrocarbon, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a view in elevation, partly in section, of a stove having a burner or lamp constructed in accordance with the present invention disposed thereon, the burner-head of which is in section. Fig. 2 is a view in plan of a burner-head with the cap'removed.

Referring to the drawings, A designates a stove-casing, which may be of the usual or any preferred construction, in which is removably disposed the burner or lamp of this invention, comprising a body or reservoir 1, which may be constructed of any suitable material, preferably of sheet metal, a wick-tube 2, detachably connected therewith, and the burner 3. The burner comprises a head 4, preferably circular in plan and provided with a tubular extension or neck 5, into which the upper end of the wick-tube is adapted to fit. The upper side or face of the head is approximately cone-shaped and is reduced in thickness adjacent to its periphery to present a shoulder 6, against which is adapted to bear the inner face of the marginal wall or flange 7 of the cap, the periphery of the cap, as also that of the head, being projected laterally some distance beyond said flange to present flame-deflectors 8 and 9, as clearly shown in Fig. 1. The top of the cap is flat, and adjacent thereto is a series of gas-escape orifices 10, of which there may be any desired number, these orifices being of small diameter in order to present resistance to the escape of gas, and thus prevent waste, and at the same time to enhance the projecting properties of the flames or jets to cause them to be driven the opening 13 is a series of circularly-disposed orifices 14, through which the gas escapes into the vaporizing-chamber, which is composed of the head of the cap thereof, and

thence escapes through the openings 10, as.

has already been described.

In order that the discharge of the gas from the openings 10 shall be intensified, for the reasons before stated, the combined areas of the orifices 14 are greatly in excess of the combined areas of the openings 10, so that there will always be a volume of gas seeking exit which will be held back through its inability to escape through the openings 10 in a volume greater than desired, and this backing up or accumulation of gas within the vaporizing-chamber will cause a sufficient pressure to be generated to effect rather violent escape of the gas. By reason of the coneshaped top of the head the incoming gas will be caused to impinge the under side of the cap, owing to the fact that the apex of the head is adjacent thereto, and is thence deflected laterally, and this arrangement constitutes, in fact, an equalizing-chamber to effect equal distribution of the gas to all of the escape-openings 10. The wick 15 terminates a short distance below the top of the wicktubesay one-eighth of an inch-so that there is space provided to permit the vaporized fluid to spread and escape equally through each of the feed-orifices 14.

In the use of the burner a torch containing gasolene is ignited and is held beneath or close to the head 4:, whereupon the contained air will be driven therefrom and a vacuum will be set up, which will operate to draw the vapors from the upper end of the wick into the head, and as the head becomes heated from the torch these will be vaporized and will escape in the form of a gas. After the gas is once ignited the head will become heated and will operate in a manner that will be well understood to effect proper vaporization of the fluid. It will be noted that capillary feed is relied upon to conduct the fluid to a point adjacent to the head, and its conduction thence into the burner-head and without the same is secured by vaporization. By thus utilizing the gasolene, danger of waste from dripping or explosion is positively obviated,

and all of the gas generated will be conserved to accomplish effective work.

If at any time the gas-escape openings 10 should become clogged, as from an accumulation of carbon, this may readily be removed by employing a stiff brush or a fine wire; but

it this fails to dislodge such accumulated matter the cap may be detached from the head and placed in a coal fire until red-hot, when any such obstructing material will disappear.

Having thus described the invention, what I claim is 1. In a device of the class described, a burner comprising a head provided with a plurality of gas-inlet openings and with a cone-shaped upper face, and a cap provided with a plurality of gas-escape openings, the combined areas of the gas-inlet openings being in excess of the combined areas of the gas-outlet openings, thereby to maintain a pressure within the head.

2. A device of the class described comprising a head provided with a plurality of concentrically-disposed gas-inlet openings, the

periphery of the head being reduced to present a circumferential shoulder, a cap having its inner face in engagement with the shoulder and provided with a plurality of gas-escape openings, and a removable assembling device disposed centrally of the cap and of the head.

3. A device of the class described comprising a head provided with a plurality of gas-inlet openings and having its upper face coneshaped and its lower face provided with a tubular neck, a cap detachably connected with the head and provided with gas-escape openings, and a wick-tube detachably connected with the neck, and disposed some distance below the gas-inlet opening.

4. The combination with a wick-tube, of a wick having its upper end terminating below the like end of the tube, and a burner comprising a head having a tubular neck to engage the tube and provided with a plurality of inletopenings and with a cone-shaped upper face, and a cap detachably connected with the head and provided with gas-escape openings.

In testimony whereof I have hereunto set I re my hand in presence of two subscribing witnesses.

CHARLES OANNOM. Witnesses:
