FUEL-BURNER.

Application filed March 3, 1913.

To all whom it may concern 7 Be it known that I, CHARLES F. PETER- soN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain. new and useful Improvements in Fuel- Burners, of which the following is a specification.

This invention relates to improvements in liquid fuel burners and has for its object to provide a simple, efficient, and inexpensive burner adapted to provide a heater whereby heat may be diffused very effectively and evenly from a comparatively small combustion chamber.

A further object of my invention consists in providing, in a device of the kind described, improved means for stimulating the inflow of air to the combustion chamber, and also to provide suitable passages for conveying air heated during its transit through the heater. I

With the above and other objects in view my invention consists in the combination,

arrangement, and details of construction disclosed in the drawings and specification and then more particular pointed out in th appended claims.

In the drawings, wherein similar reference characters designate similar parts throughout the respective views, Figure 1 is a vertical elevation of my heater, partly in section and broken away, showing the combustion chamber from the side, Fig. 2 is a cross-sectional elevation of my invention with the surrounding open-ended hood removed, Fig. 8 is a top plan view of my heater with the hood removed, Fig. 4 is a fragmental detail view of one end of my wick-containing chamber, Fig.5 is a detail sectional view of a wick-controlling device, Fig. 6 is a transverse, fragmental sectional View of Fig. 4, Fig. 7 is a longitudinal sectional view of Fig. 5, Fig. 8 is a bottom plan view of my heater, and Fig. 9 is an end elevation of my heater. 1

Referring to the drawings which are merely illustrative of my invention, an oil reservoir is designated 1 which is provided with a handle 2. A plurality of substantially rectangular draft air tubes or conduits 3 are disposed within reservoir 1 and extend above the top of said reservoir. Two of these draft tubes are shown, although if desired, the number may be increased. Four wick-containing members 5, extend longi- Specification of Letters Patent.

tudinally in said reservoir projecting partly above and partly below the same. Two of these members 5, it will be noticed, are on opposite sides of each of the tubes 3, and are connected at each end and at their sides by the substantially channel-shaped member 20, as is shown in Fig. 4. Each member 5 is hollow throughout and is formed at its upper end with a reduced wick-guiding part 6. Arranged in member 5 in slidable relation is a wick-carrier 7 formed terminally with rightangular flanges 8, the upper portions 9 of which are reduced, and having racks 10 formedthereon. A rod 11 passes through the member 5, one of its extremities serving as a lug 12, which together with the opposite projecting portion carrying the handle disk 13 is arranged to take into one of the slots 14 formed in the members 20 at their opposite ends, serving thereby to hold the wick containing member 5 in position in member 20. Pinions 15 are formed upon rod 11, at suitable points, arranged to mesh with the racks 10, whereby carrier 7 may be raised and lowered; The wick carrier 7 is formed longitudinally, at spaced-apart points, with spring arms 16, portions of which lie flatly secured upon said carrier, while portions 17 curve outwardly and upwardly terminating in angular serrated portions 18 arranged to project into the wick 19 so as to hold the same supported relatively to the carrier, said wick 19 extending longitudinally of the member 5. It will be noticed that the air draft tubes 3 extend into the oil reservoir, as shown in Fig. 2. The usual closure cap 23 is screw-threaded into the oil reservoir.

A four-sided casing 24 having supporting legs 25 is arranged to rest upon the oil reservoir and it extends around the partitions and said wick container so as to form a combustion chamber. Extending all aroundthe top edge of casing 24 is an outwardly-extending rim 26 and said rim, at opposite sides is formed, laterally of said member 24 with a series of longitudinallyextending ports 27. Formed longitudinally of casing 24 are the spaced-apart strips 27 which are V-shaped in cross-section and having a series of ports 28 formed along the vertex line of each strip, each strip being disposed in alinement with the air conduits 3.

The member 24 is formed, substantially at each side of a median line with oppositelyarranged longitudinally-extending partition interspace between the walls 29.

-with the rightangular handles 42.

walls 29 which are arranged to project into the space 29" between the two innermost wick-containing members 5, and intermediate of the walls 29 is a similarly disposed plate 30 which extends some distance below said walls. A deflector member 31 extends centrally and longitudinally of casing 24 at its top and is arranged directly over the walls 29 and plate 30, said member 31 being formed with marginal flaring portions 32 to conduct and deflect air over the wick-containing members 5. The rim 26 of casing 24 is formed at its longitudinally-0pposite sides with the downwardly inclined portions 33 which are bodily disposed over the outer members 5. The openings 34 are formed upon the opposite end walls 35 and 36 of member 24, and when the latter is mounted in position upon the oil reservoir, said openings 34 will communicate with the It will also be noticed that the walls 29 are formed with upwardly and outwardly inclined portions 37. To prevent the displacement of the member 24 from the oil reservoir any suitable arrangement may be used, that shown embracing the rolled members 38 which are secured upon the members 20, holes being formed upon the corners of said members 24 as at 39, which register withthe rolled members 38 so that the removable rods 40 may pass through said holes and said rolled members and hold casing 24 against vertical displacement. It will be understood that wick 19 will project into the oil in the oil reservoir 1.

If desired the tubular member 41 may be caused to rest immediately above the easing 24, so that the device may be used for cooking purposes. The rods 40 are formed This member 41 will be supported upon the standard 45.

W hen the wicks are lighted, and properly regulated, combustion will be stimulated by currents of air. These currents of air will be drawn in through the channel 29' formed between the inner wick-containing members 5, or through the air conduits 3, which currents of air will be directed by the inclined portions 37 upon member 31 whose inclined portions 32 will deflect the air downwardly so as to mix with the products of combustion emanating from the wick-containing members 5. The walls 29, plate 30, and the sides of casing 24 form relatively-large heat-radiating surfaces, the air being heated while passing upwardly between the walls 29,

as said walls will radiate heat. The heated products of combustion will impinge upon the downwardly-extending portions 37 whereby they will be deflected against the sides of the casing 24, raising the temperature of the same. Unheated air may flow to the wick-containing members through the top open end of casing 24, down member 41. Circulation of air is very nicely had by way of the air conduits 3, and it will be understood that the oil reservoir will be supported upon any suitable standard 45 arranged to support the oil reservoir along its edges to cause air to pass upwardly through said conduits, this air dividing in opposite paths as it impinges against the V-shaped strips 27 so as to pass over the members 5, part of this air making exit through the ports 28 formed upon the strips 27. In this way the heater will not smoke and no annoyance will be caused from the use of hydrocarbons as fuel. When the tubular member 41 is in' use, air may pass through the ports 27 to promote combustion.

Numerous modifications may be resorted to in practice without departing in principle from the details of construction herein disclosed.
