T at whom it may concern.-

Be it known that I, ABNER B. HUTGHINS, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification.

My invention relates to oil-stoves, and more particularly to oil-stoves of the blue-flame IO type, and the invention isdirected more particularly to the burners in such stoves.

The invention will be fully described hereinafter, and the features'ofnovelty pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a transverse Vertical sectional viewof one form of oil-stove embodying my invention. Fig. 2 is a fragmentary transverse sectional view of the wick, the wick-trough, the oil-pipe, and adjacent parts of the structure. Fig. 3 is a front view, partly in section, of the stove represented in Fig. 1. Fig. 4 is a detail plan view, with parts broken away, of a modified form of cylinder construction. Fig. 5 is a central vertical sectional view of a modified form of burner construction. Fig. 6 is a detail top view of one of the rings. Fig. 7 is a bottom view of the same. Fig. 8 is a transverse sectional View of a series of the rings represented in Figs. 6 and 7. Fig. 9 is a fragmentary bottom view of the top ring of the outside cylinder represented in Fig. 5. Fig. 10 is a traus verse sectional View of the same, together with some of the cooperating rings.

The burner may be made by constructing what I term the inner cylinder A of a plurality of superposed rings B or segments a, Fig. 4., which are spaced apart by suitable meanssuch, for instance, as lugs bpro- 4o Vided on each of the rings or segments and adapted to maintain them spaced apart, so as to form narrow slots or openings 0 between each pair of superposed rings or segments. These slots are intended to take the place of 4; the openings in the ordinary sheet-metal cylinder heretofore used and. permit the air .to pass from the interior of the cylinder A, formed by these rings or segments, to the outer portion thereof, where the ignition of oil takes place. Suitable means are provided to maintain the superposed rings, sections, or segments in the operative position. Thus,

for instance, one such means consists in providing grooves or depressions e in the face of each ring, into which the lugs 12 on the opposite face of the ring below is adapted to pass inorder to secure the rings against lateral displacement with relation to one another and so as at the same time to provide the proper space or openings between the various rings for the passage of air from the interior of the cylinder A to the outside thereof, as shown in Figs- 6, 7, and 8. Where segments are employed to make up thecylinder, each segment a is preferably provided with a plurality of lugs 19, and the superposed segments are preferably arranged so as to break joint, as represented in Fig. 4 of the drawings, thus uniting all of the segments one to another to form the cylinder. A defiector plate f is preferably provided at the lower portion of the inner cylinderAto prevent a too-rapid admission of air to the interior thereof. In certain instances I prefer to employ an interior foraminous sheet-metal air-distributing cylinder 0 within the so called"inner cylinder A. This sheet-metal cylinder 0 assures the proper distribution of air to the cylinder A and may be made of sheet metal without injurious effects, by reason of the fact that ignition or flame is outside of the cylinder A and does not attack this air-distributing cylinder 0. Air passes between the deflector-plate f and the centrally-apertured plate g to the interior of the cylinder 0 and passes out through the perforations h.

The plate'g prevents air from passing into the cylinder A except by way of the perforations in the cylinder O.

The various segments or rings making up the inner cylinder A are secured together and to other portions of the burner by any suitable means, preferably by a plate D, whichv cure the parts in placeand by'which neans the parts may be readily disconnected for the purpose of repair;

The plateD is preferably provided with an upturned flange it, which is perforatedor apertured, as indicated at Z. These perforations permit the flame to be deflectcd toward the center of the burner, as indicated by the arrows, and thus provide a burner of greater efficiency than would be the case where a mere ring of flame is produced.

At the lowermost portion of the inner cylinder A and at the outside thereof I provide an annular trough E, which preferably supports a loose ring-like asbestos wick F in place. This wick extends into the trough, to which oil may be conveyed by a suitable pipe on, and any desired means, such as are indicated at G, are provided for regulating the amount of oil which flows to the trough from a suitable reservoir H connected to the stove.

Surrounding the so-called innercylinder A and the wick and concentric therewith is a second cylinder 1, which may be made of foraminous sheet metal, as shown in Figs. 1 and 3, because of the fact that this second cylinder is not attacked by heat to such a degree as is the inner cylinder A. However, in certain circumstances it may be considered advisable to make up this second cylinder in the same manner or substantially the same manner as the inner cylinder A, except for the fact that there will be no top plate upon the uppermost ring.

In Fig. 5 Ihave illustrated the second or outer cylinder J, which is made up of a plurality of rings or segments. In this construction the separate rings or segments a may be secured together by forming ears or lugs 0 upon the uppermost and lowermost rings and passing rods or boltsp through these ears and through lugs formed on the flange q of the outer imperforate drum K, so as to maintain the entire series of segments or rings fixed with relation to one another and with relation to the drum. The space between the inner and outer so-called cylinders A and K or A and J, as the case may be, is Where the ignition takes place, and the outer cylinder is surrounded by the drum K, so as to form an air-space 00, whereby air may enter at the bottom and escape at the tap. The drum K is connected to the outer cylinder, and the two are adapted to be raised together, so as to give access to the trough to enable the operator to ignite the burner. For this purpose I have shown a yoke L, the free ends of which are adapted to be seated in sockets r in the drum K and which moves in avertical direction in guideways s. A lever M is pivoted to the frame of the stove, as indicated at i, and the free end of this lever extends through a slotted plate a, in which a notch o is provided to support the lever M, yoke L, drum K, and the cooperating outer cylinder in the elevated position to give access to the wick to ignite and extinguish the flame.

It is obvious that the burner construction may be employed in an oil-stoveof anysuitable or desired construction and that the essential features of my invention are directed to the burner construction itself without relation to the character of the stove in which it is employed.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In an oil-stove, the combination of an inner cylinder made up of a plurality of superposed cast-iron rings of uniform size and shape having air-passages between them, imperforate means for closing the top of said cylinder, means for admitting air to the interior of said cylinder at the lower end thereof, an outer cylinder having openings therein, which outer cylinder surrounds and is concentric with the inner cylinder and an imperforate drum surrounding the outer cylinder and so spaced with relation thereto as to provide an air-space between said drum and outer cylinder.

2. A stove comprising a perforated outer cylinder and a perforated inner cylinder one of which is formed of a plurality of superposed rings of uniform size and shape suitably spaced apart and forming a combustion or flame chamber between them, a wicktrough located at the bottom of said chamher, a perforated air-distributing cylinder located within the inner cylinder, an imperforate top plate for closing the upper end of the annular space between the air-distribut- -ing cylinder and the inner cylinder, and an imperforate bottom plate extending from the lower end of the air-distributing cylinder to the wick-trough.

3. A stove comprising a perforated outer cylinder, a perforated inner cylinder spaced therefrom, one of said cylinders being formed of a plurality of superposed rings of uniform size and shape and suitably spaced apart, means for forming a flame between the said cylinders, an air-distributing cylinder located within the inner cylinder, a base or frame for supporting said cylinders, a top plate engaging the inner cylinder and the air-distributing cylinder, and a bolt extending from said plate to the base through the central space surrounded by the air-distributing cylinder.

4. A stove comprising a perforated cylindrical structure composed of a plurality of superposed rings suitably spaced apart,1neans located at one end of the structure for form ing an annular flame around said structure, and an imperforate plate for closing the end of the central space surrounded by said structure, at the other end of the structure.

5. A perforated cylinder for stoves consisting of a series of superposed rings each of which has an annular groove on its lower surface and is provided on its upper surface with lugs arranged to project into the groove of the next ring above and to space adjacent rings so as to leave an air-passage between them.
