Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed August 8, 1914. Serial No. 855,860:

To all whom it may concern.-

Be it known that I, LEE S. CHAnwIoK, a citizen of the United States, residing at East Cleveland,-in the county of Cuyahoga and State of .Ohio, have invented a certain new and useful Improvement in Oil-Stoves,

of which the following is a full, clear, and,

exact description, reference being had to the accompanying drawings.

This invention relates to oil burners, and more particularly to burners of this type which are adapted to produce a flame suitable for use, in a cooking stove. The various embodiments of the invention include a wick as the means whereby the oil is fed to the vaporizing point and whereby a vaporevolving surface is provided. The various forms of the invention shown herein also relate to burners of the type whereina blue flame is produced through the manner of supplying air to the vapors evolved from the upper and exposed end of the Wick and wherein, for this purpose, a centrally arranged air distributer of controller is pro vided within the upper end of the inner wick tube and a cooperating air distributer is provided outside of the outer wick tube and between the same and the surrounding an instance of such burners being drum, shown in the patent to Hoffman No. 1,092,262, issued April 7 1914:.

It is the general object of this invention .to improve the operation of burners of this type and particularly in the matter of safety, rendering the same practically immune from the dangerous conditions arising from thedischarge of vapors about the lower ends of the wick tubes. These. vapors, catching fire, will generate vapors from-the wick tubes in such quantity as to be incapable of proper combustion and control, While the heat produced by the combustion of the vapors about the bottoms of the wick tubes will break the connections in the oil supply to the wick tubes. whereby the. oil may be ignited at the points where such breaks occur and the compartment in which the stove is located and the life of the operator be endangered thereby. W'it-h the foregoing general object in view, the invention may be defined further as consisting of the combinations of elements embodied in the claims hereto annexed and illustrated in the drawings forming part hereof, wherein Figure 1 represents a vertical sectional view of a burner constructed in accordance with my invention, including the lower portion of the drum or chimney; Fig. 2 is a transverse sectional view, with parts broken away, corresponding to the line 22 of Fig. 1; Figs. 3, 4. 5, and 6 are vertical sectional views of modifications of the burner shown in Figs. 1 and 2.

Describing by reference characters the various parts illustrated herein and with partieular'reference to Figs. 1 and 2, 1 denotes the inner and 2 the outer wick tube of the burner, 3 a lateral supply connection projecting from the bottom of the outer wick tube and 4 a hook which. is secured to the inner wick tube, said connection and hook forming means whereby the burner may be connected to and the space between the wick tubes be placed in communication with the supply pipe (not shown) in the manner described in patent to'Jeavons 951,612 dated March 8, 1910. 5 denotes the wick which is mounted within the space between the wick tubes, said wick being provided with a carrier 6 which is adapted to be engaged and operated by a wick raising wheel 7. The upper end of the inner wick 'tube is preferably bent or deflected outwardly, as shown at 1, while the upper end of the outer wick tube is bent inwardly. as shown at 2. and then upwardly, as shown at 2", and the top of the inner wick tube the inner wick tube, this annular plate or ring forming a seat for the air distributer' which is within the top of the inner wick tube. This distributor comprises a body (preferably hollow) which is mounted with- "in' the upper portion of the inner wick tube,

said boi'ly'being preferably in the shape of two cone frustums placed base to base and supported on the ring, whereby the lower the last mentioned portion of the body forms'with. the top of the inner wick tube a passageway of diminishing cross sectional area from bottom to top, the upper portion of the distributer pro'ecting inwardly slig tly above the top of the inner tube. at 9, is provided witha bottom 10, an inverted frusto-conical wall-11, and a frusto conical wall 12 projecting upwardly from wall. The-wall 11 is provided with a suitable number of outwardly projecting supporting :devices, shown as plates 13 four being shown), the lower ends whereof are adapted to rest upon the ring 8, the plates being preferably of such extent as to be in substantial engagement with the inner wick tube, whereby the distributer wick - may be centered. .It will be observed that the passageway formed between the bottom portion of the distributer 9 and the inner minishing cross sectional area as far as the top portion 1' of 'thewick tube and that, from the bottom of this portion'l the diminution in cross sectional area of the passageway, while uniform, served also'that the'plane of greatest width ofthe distributer 9 is slightly below of the wick, when the wick is in position for normal operation.

.The outer wick tube is shown as provided with an outwardly projecting ledge 14, which may conveniently be provided by doubling the metal thereof upon itself. On

the seat thus formed is supported the chimney or drum and the parts which cooperate to distribute air to the exterior of the wick andthe exterior of the flame. 15 denotes a'vertical ring or collar which surrounds the upper portion of the wicktube, The bottom of this collar is shown as supported by the ledge 14 and the collar is cylindrical I in contour as far as the top of the outer wick tube, where it is flared outwardly, as shown at 16. The bottom of the collar preferably fits the outer wick tube closely, the

- portion of the collar which is opposite the this channel or trough parts, 2 'and 2 of the outerwick tube formingtherewith a trough or channel 2. The part of the collar forming the outer wall for is provided with 'a limited number of perforations 15* through which air may enter the channel and, sweep ing upwardly, carry with itinto the flame above any vapors that may drop into the channel from the vapor of j the wick thereabove.

also provided with perforations The flange 16 is '16, which the space immediately surrounding the outer exposed surface of the wick. v I

tion, there will be a slight space (about g -g inch) between the top of the flange and the wick. In the of the second air distributing element, a suitable number of large openings 19* will be provided, two horizontal series of such openings being shown. In the lower portion of the cylindrical part 22 of this element a series of large perforations 22 will be provided, said perforations being located below the flange 16. It will be evident that the first and second elements form in effect a unitary structure, both of which are supported byvthe ledge 14, and that a chamber is provided thereby which extends about the up er end of the outer wicktube.

he third element of tributer. comprises .a cylindrical body 24 of sheet metal) which is of a diameter to enable it to be slipped over the cylindrical portioi 20 of the second distributing element an to enable the body to be supported in engagement with the ,frusto-. conical portion 19 of the second element. At its bottom, the third element is provided with an outwardly projecting flange 25.v The upper end of the third element is ex-v tendedupwardly and inwardly and is pref- .inn'eredge 27 preferably in vertical alinement with the inner edge 23 ofthe element therebeneath. The downwardly and inwardly projec t ing portion of this third element is provided with perforations, as shown at 26. The thirdelementprovides a passageway with the second element for conducting vapors and air into the space above the wick.

The chimney or lindricalandof the type shown in Jeavons' Patent No. 1,038,590 issued Sept. 17 1912,

frusto-conical portion 19? With the burner operating in normal condithe externalair disdrum 28 is preferably cy- I whereof may be formed into a wire, as

will be shown at 30, the inner diameter of the wired portion being such as to fit more or less closely about the cylindrical portion 24 of the third air distributing element, the drum being supported by the flange or ledge 25.

The inclined or inverted frusto-conical portion of the drum is provided with perforations 29.

With the parts constructed and arranged as described, the operation will be as follows: The wick being turned up to about the position shown in Fig. 1 and ignited, vapor will be generated from the exposed top portion of the wick. Owing to the manner of supplying and distributing air, the flame,

a blue flame extending upwardly in the space between the top of the air distributer 9 and the inner edges 23 and27 of the exteriorly arranged overhanging plates. When operating under ordinary conditions, there is liability that some vapor evolved from the outer -surface of the wick will not be carried upwardly and will, in fact, fall downwardly about the upper end of the wick tube. Such vapors will accumulate within the trough 2 and will be carried thence upwardly into the flame by air admitted through the openings 15 and 16.

In a'burner constructed as shown herein, the particular arrangement of the inner and outer distributers will secure an efiiciency which is greater than that of any other burner of the particular type illustrated herein with which I am familiar. In operation, however, the wick. may be turned so high as to impinge against the lower edge 23 of the inwardly extending distributer flange t-hereabove, or it may be brought into undue proximity thereto. The flow of vap'ors from the major generating portion of the wick will then be entirely cut oil or materially checked, as the case may. be. In either event, vapors evolved from the outer portion of the wick will fall by gravity. In all other burners of the particular type shown herein with which I am familiar, these vapors will drop into close proximity to the outer wick tube and, being ignited there, will evolve vapors from the wick tubes in such quantity as will produce a flame which will not only be intensely smoky'but will be incapable of control. Furthermore, the continued burning ofvapors at this point will loosen or break the connections between the supply pipe and the burner,

/ with attendant. danger of conflagration. By the construction illustrated herein, should the operator happen to turn' the wick too high, the vapors evolved from the outer exposed surface of the wick will fall into the surrounding chamber and then be caught into the "flame.

when the wick is at normal height,

ring 8, and

lower portion 31 which may have a by the air flowing through the openings 19 and swept through the openings 22 into the passageway between the second and third elements of the external distributer and be discharg d above the top of the wick and As a further precaution against any inconsiderable quantity of va- I pors which might pass out through the openings 1 9 (the bottom wall 17 being imperforate) these vapors will be caught by the air flowing upwardly through the openings 29 and above the flame therein. Finally, should any vapors thus liberated from the external surface of the wick fail to be taken care of through the two passageways provided therefor, the flange 11 will discharge these vapors at a point sufliciently remote from the wick tubes to prevent the undesirable consequences referred to hereinbefore, even if the vapors should be discharged in a sufficient quantity to.v produce a flame of any material extent-a remote contingency.

In Fig. '3 there is shown a modification of the invention illustrated in the preceding figures wherein the parts which are identical or substantially identical with those in the preceding figures are given like reference numerals. The inner and outer tubes, the; the bottom part ofthe inner air distributer are identical in construction with the like numbered parts in the preceding views, The upper part of the inner distributer, instead of being frusto-conical, is shown as outwardly concaved, as shown at The collar or ring 15 is omitted in this. modification, and an outwardly and downwardly directed annular plate 17 ismounted upon the outer wick tube and extends therearound in about the samemanne-r as the plate 17 shown in Fig. 1. The outer portion of the plate 17 is provided with a vertical flange 17 and with a horizontal flange 17 therebeneath, the flanges forming a. seat for the lower wired end of an external distributer element which is similar to the element comprising the parts 19 to 23 in the preceding view. In this case, the external distributing element comprises a cylindrical single series of large openings 32. The metal of this distributer element is shown as bent horizontally inwardly, at 33, and then upwardly in cylindrical form, at 34, the upper end being convex, as shown at 35, the extreme inner edge 36 of this convex portion being in the same positionwith reference'to the wick therebeneath as the edge 23 of the corresponding element in the preceding modification. The cylindrical portion 34 is, shown as provided with a series of large openings 3%, corresponding to the openings 22 in the preceding views. Outside oft-he distributingelement just described is located another element corresponding to the eleand will be carried into the drum ment 24-27 in the preceding figures. This element is shown as having a cylindrical portion 37, which is of a diameter to fit more or less closely upon the cylindrical portion 31 of the distributer element just described and to which it may be permanently secured,

' as by peening the overlapping portions of the metal together, as indicated at 38. The bottom of the cylindrical portion 37 is shown as formed into an outwardly proj eoting flange 39 and the top of the element isbent into convex form, as shown at 40, whereby it overhangs the corresponding part of the element therebeneath and forms therewith a passageway which diminishes in cross sectional area to the discharge outlet formed between the alined inner edges 41 and 36.

distributing downwardly inclined portion.48, and a .cyk

lindri cal portion 49. The parts 45 to 49 may conveniently be "made 0 of metal and the cylindrical part 49 of this a single sheet element is adapted to be fitted to'the topof the outer wick tube in the same manner as is the cylindrical portion 43 of the element 42-44 in Fig. 3. It will be evident that the upwardly and outwardly extending .por-

The distributer plate may then be bent downwardly, as shown at 60, to fit within the top of the sleeve 50, to which it may be secured, as by peening the metal together (see 61). The plate is then bent inwardly and downwardly above the part 55' of the distributing element therebeneath, forming therewith a passageway which diminishes in cross sectional area toward the inner or discharge end. This inwardly projecting portion is shown at 62, and the extreme inner edge 63 thereof is located above the inner edge 56 of the element therebeneath. The inwardly projecting portion of the last described element is provided with perforations, indicated at 62.

The operation of the burner disclosed in Fig. 4 will be substantially the same as that of the burner shown in the preceding views, except that no perforations are provided enter the trough or chamber formed about the outer exposed portion of the wick. Should the wick be turned unduly high, any

vapor evolved from the outer surface of the Wick will be directed outwardly by the inclined wall 47 and will practically carried through the openings 54 into the passagewaybetween the

plates

55 and 62 and be discharged mainly through the slot between the edges 56 and- 63 into the flame. Some of' the vapors will bedischarged through the openings 62. It will be observed that, in this modification as well as vapor that may overflow through the openings, will be practically entirely caught by thedraft passing upwardly through the openings 59", and any thatmay not-be carried through either of the separate paths thus provided, will be discharged at a sufficient distance from. the burner to avoid danger, eve-n should they be present in a quantity suflicient otherwise to cause such danger. 4

The outer horizontal flange 45 of this member is engaged by the outer edge of an upwardly inclined plate 17, the'lower end ofwhich is secured to the. approved manner. The outwardlyv projecting flange 45 and the cylindrical portion 46 coiiperate to center and support thereupon a sleeve which is substantially identical with the sleeve 50 in the preceding figure, which sleeve and its component parts. will be-numb'ered in like manner as in the preceding figure. At its upper end, the sleeve is secured to a cylindrical portion of an air distributer member which is similar to the member 5863 in Fig. 4. This distributer member is preferably made from a. sheet metal plate and has its outer edge provided with an upwardly projecting cylindr igal e plate is then shown as bent inwardly, at 65, to form a horizontal ring having pe-rfora Thence it is shown as bent downwardly to form a cylindrical flange 66 to which the sleeve 50 may be secured, as by peening (see 66) From the bottom of the cylindrical part, the distributer plate is shown as projected inwardly and downwardly, at 67, being of substantially the same shape as the part 62 in the preceding modification.

as to avoid danger.

In Fig. 6 there is modification of my invention inner and outer tubes, the inner air shown a still further wherein the distribparts 4549, the members, 17, the cylindrical sleeve'fiO, the drum 28" and the air distributing member comprising the parts 64-68 are identical with the like numbered parts in the preceding figure, the only difference in construction being that the intermediate external air distributing element, instead of being carried by the element 6468, is carried by the sleeve 50. This intermediate member is preferably formed of-a plate of sheet metal and is shown as having its outer end formed into a cylindrical flange 74 by which it may be secured to the sleeve 50, as by means of peening (see 74;). The body of the plate then projects inwardly, as shown at 7 5, and has its inner portion upwardly the extreme inner edge 77 occupying the same relation, with reference to the top of the wick and the inner edge 68 of the distributer member thereabove as is the case with the corresponding part in the preced- Thesleeve 50 is provided with a series of perforations o0 'communicating with the space between the upper and the intermediate air distributing elements.

The operation of the burner shown in the last described figure will be identical with the'operation of that shown in the preceding figure except that any vapor which may flow down the inclined wall 47 of the chamber surrounding the upper end of the outer wick tube will accumulate above the openings 51 until it can flow therethrough, when it will be caught by the upward draft of air and be carried through the openings 50 into the passageway between the

plates

67 and 55 and be'discharged into through the openings into the drum;

Should any considerable quantity of vapors wick tube, a wick therebetween,

fail to be thus disposed of, they will be conducted away from parts which might be endangered through their combustion.
