OIL-BURNER.

Specification of Letters Patent.

Application filed August 20, 1914. Serial No. 857,733.

To all whom it may concern:

Be it known that I, CAR E. BROWN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Oil-Burner, of which the following isa specification.

' The present invention appertains to liquid fuel or hydro-carbon burners, and aims to provide a novel and improved burner adapted to be utilized in a convenient and effective manner within the fire box of a cook stove, although it is to be understood, at the outset, that the present burner may be employed in various capacities for heating purposes. v

It is the object of the invention to provide a hydro-carbon burner applicable to the fire boxes of cook stoves, and embodying a swing'ably mounted retort or generator adapted to be heated by the flames, and whereby the flames may be directed in various manners, as desired, without interfering with the heating of the retort or generator, so'that when the burner is applied to the fire box of a cook stove, the flames may be either directed upwardly through the lid openings or against the lids of the top of the stove, or may be directed rearwardly over the oven to heat the oven effectively and with a minimum amount. of fuel.

Another object of the present inventionis to provide a burner having a priming device or means, to and from which the generator or'retort is movable, in order that the burner may be readily primed when the retort or generator is swung immediately over the priming device.

It is also within the scope of the present invention, to provide a unique assemblage of component parts, whereby the utility of the burner will be enhanced, and the burner rendered thoroughly practical and efficient.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in i the details of construction hereinafter depreferred embodiment in the accompanying drawing, wherein Figure l is a plan view ofthe improved 'Patented Dec. 1, 1914.

burner. Fig. 2 is a rear view thereof. I Fig. i

an air chamber therein, the shell 2 being seatable upon the grate within the fire box of a cook stove, and serving to direct the air upwardly from the grate to the flames, as will hereinafter appear.

The plate'I is provided with a pair of openings 3 and with integral domes 4 disposed over the openings,3. The plate 1 may be provided with any number of the openings 3 and domes 4, according to the length of the burner, the use of two or more openings 3 and domes 4 being a mere duplication or multiplication. The plate 1 is also provided with a depressed channel or gutter 5 extending longitudinally thereof along its rear edge and in rear of the openings 3 and domes 4, the gutter or channel 5 serving as an elongated priming cup which may hold asbestos, ashes, or other absorbent material for the liquid fuel.

There is provided a U-shaped pipe 6 having its arms disposed horizontally, the lower arm 7 of the pipe 6 being journaled throughthe sides of the domes -1, longitudinally of the burner bodj constituting the plate 1 and shell 2. The arm or limb 7 of the pipe 6 serves as a vapor tube, while the other arm or limb 8 of the pipe 6 which is disposed above the domes 4, serves as the retort or generator. The arm or vapor tube 7 being journaled through the sides of the domes 1, enables the retort or generator'8 to be swung above the domes toand from the priming cup or gutter 5. In order to supply oilor other suitable liquid fuel to the'retort or generator8, a

pipe 9 is attached to the free end of there tort or generator 8. and extends to the'axis of the arm or vapor tube 7, and apipe 10 which is in alinement or coaxial with the arm or tube 7, is attached to the pipe 9, and has attached thereto, a suitable controlling" valve 11. The pipe 10 is adapted to be journaled through one end or sideof the fire box, whereby the valve 11 will be disposed exteriorly of the stove to be readily controlled and to be swung for oscillating the retort o'r generator 8. The valve 11 may be connected by'a flexible supply pipe or conductor 11 to a liquid fuel tank or other source offuel.

A cap or closure 12 is engaged over the free end of the arm or tube 7, and the said arm or tube 7 is preferably supported by ears or seats 13 upstanding from the ends of the plate 1. p p

The vapor tube 7 is provided with lateral outlet apertures it within the domes st, and

directed toward the retort 8, and the domes v.

4 areprovided with uppei; openings and rear openings or slots 16 tnrough which the vapor or gas may pass from the apertures 1 1 of the vapor tube 7. The vapor outletapertures 14 therefore cooperate with the openings 15 and 16 of the domes 1, to enable the jets or streams of gas issuing from the apertures 14 to pass through the respective openings 15 and 16 according to the position oft-he retort. I

Spreaders 17 are carried by the retort or vaporizing tube 8, the spreader-s 17 having the collarsl8 embracing the retort 8, and the spreaders 17 being so arranged with respect tothe apertures 14;, that the flames will impinge against the spreaders 17 to be spread thereby over a considerable area.

In order to enable a small quantity of the liquid fuel to be discharged into the prime ing cup 5, from the vapor tube 7, inclined troughs 19 of. sheet metal. or other suitablematerial, have their lower ends secured in any suitable manner to the outer side of the S priming cup 5 at the lower ends of the openings or slots 16, and project below the vapor'tube 7 above the openings 8, whereby the upper ends of the troughs 19 lie below the apertures 14. Thus, any oil or liquid fuel which is permitted to spurt or flow through the apertures 14:,will be caught by the troughs 19 and conducted into the priming cup or channel 5.

A bracket 20 is terminally secured to the forward and rear edge portions of the plate 1 between the-two domes 1, and is provided with an upper notch 21 over which the retort 8 is engageable when the retort is swung upwardly, and the rearward portion of the notched bracket 20 is provided with a seat or shoulder 22 against which the retort 8 is seatable when the retort is swung to its lower or rearward position.

In use, the burner may be readily applied, Within the fire box 23 of a cook stove, as suggested in- Fig. 3, with the priming cup 5 disposed adjacent the back of the fire box,

and with the pipe 10 journaled through the corresponding end or side of the fire box. The valvell is flexibly connected to the fuel and downwardly, as desired. l

sane

tort 8 above the priming cup 5, as indicated by dotted lines in Fig. 3, and then, by opening'the valve 11., the oil or other liquid fuel may be admitted into the pipe 6. The oil or fuel will then spurt or flow through the apertures 14. and will be conducted into the.

priming cup bythe conveyors 19. The fuel within the priming cup 5 may then be ignited, which will cause the retort 8 to be heated for starting the vaporization of the liquid fuel. The vapor generated within the retort, 8 will then pass into-- the vapor tube 7 and out through the apertures 14 to support the flames, the flames impinging againstthe spre'aders 17 to be spread thereby, and to continue the heating of the retort during the. operation of the burner. As the vapor is emitted from the apertures let and consumed, air will be drawn u ).t hrough the shell :2 and through the openings'3 to the domes 4, wherein the air will be admixed with the vapor to providea thoroughly combustible mixture. After the burner has been started, the retort Scan be swung u wardly retort 8 is swung upwardly, it will lie below the stove lids 24' or the lid openings, for effectively heating the vessel or vessels placed upon the stove, and when the retort 8 is swung downwardly, as seen in dotted lines in Fig. 3, the flames will shoot over theoven 25 for thoroughly and quickly heating the oven for baking or kindred purposes. When the retort S is swung upwardly, the flameswill pass through thcopen'ings 15 of the hen the .domes 4:, while when the retort 8 is swung downwardly, the flamesi will pass through the openings or slots 16. 111 this manner,

the flames may be either directed upwardly or in an inclined manner overthe oven 25, which will enable the burner to bereadily. used for either cooking or baking purposes, with the least amount of fuel. Furthermore, the movement of the retort enables the burner to be conveniently primed, asabove intimated.

The present burner is comparatively simple and inexpensive in construction, and is thoroughly practical and efficient in operation, the other advantages and capabilities of the device being obvious to those versed in the art, it is thought, without further comment being deemed necessary. 7
