To all whom it may concern: '1

Be'it known that we, (1) Winner! R. JEAVONS, (2) Anwonn R. Wnrrrannn', citi* zens of the United States, residing at Cleveland, in the countyof Cuyahoga and State of Ohio, have invented a certain new and its preferred form, is especially applicable to burners which are used in stoves known to the trade as smokeless heaters. Afamiliar illustration of a burner of this type is shown in the patent to Wm. R. Jeavons No. 906,887 issued December 15, 1908, where in the air distributor is provided with an outwardly projecting flange which is adapted to rest upon the top of the wick, whereby the said distributer may be carried by the wick. In burners of the type shown in the aforesaid patent, the portion of the wick from which effective vaporization occurs is the exposed outer surface of the wick-the portion included between the flange and the top of the outer wick tube. While burners of this type have gone into extensive use and have proven to be generally satisfactory, it has been found desirable to improve the construction of such burners further and particularly in such manner as to insure a uniform area of vaporizing surface from the wick under all ordinary conditions of operation. For instance, it has been found that, in the operation of burners of the type shown in the aforesaid patent, the top of the wick is or becomes more or less irregular, and this irregularity causes the outer portion of the wick to project beyond the coiiperating flange of the distributor. This results in increasing the effective vaporizing area of the wick and tends to produce an unduly high as well as an irregular and smoky flame. It is the purpose of this invention to overcome these objectionable features and to provide a burner wherein the vaporizing area of the wick will be maintained at a desired constant maximum and one wherein the spreading of the top of the wick will be positively limited. I

We realize the foregoin objects in and through the construction ilustrated in the drawings forming part hereof, wherein Specification of Letters Patent.

Application and June 1s,1e14. BerialNo. 545,992.

Figure 1 represents a vertical sectional view through a heater of the type referred to and "enlarged sectional detail of the distributer and wick tubes.

Describing by reference characters the various parts illustrated herein, 1 denotes the drum base, 2 the collar, 3 the gallery, 1 the cone plate and 5 the drum of a stove of the aforesaid smokeless heater i type. 6 denotes the inner and 7 the outer :wick tube, said tubes projecting upwardly from the usual font (not shown). 8 denotes a ring carried by the inner wick tube and provided with a plurality of inwardly projecting splder arms 9 which are adapted to engage shoulders 10 projecting from inclines 11 at thelower end of a sleeve depending from the distributer assembly. The shoulders 10 are adapted to engage the spider arms 9 and limit the elevation of the distributer (designated generally at 12) by the wick. The parts heretofore described are substantially identical with the corresponding parts in the Jeavons patent referred to hereinbefore.

The air distributer 12 comprises a cylindr1cal perforated sleeve having outwardly pro ect1ng portions 13 and 14 at the upper end thereof and a flange 15 which may be conveniently pressed outwardly from the metal of the sleeve. The flange 15 is can ried by the cylindrical sleeve 15 of the distributer and the lower end of this cylindrical sleeve is soldered or otherwise connected Patented M21125, 1918. r

to the anchoring portions 9, 10 and 11 of i the distributer through an intermediate connectingring 16, said ring being provided with a series of apertures 17 and with an upwardly and outwardly flaring portion 18,

the outwardly flaring portion 18 merging with an upwardly and outwardly inclined flange 19 the outer or peripheral portion 20 whereof is bent downwardly to form a retaining shoulder. As is the ease in the Jeavons patent hereinbefore referred to, the outwardly flaring portion 18 is provided with perforations 18*, whereby any vapor that may happen to be liberated from the inner surface of the wick may drift into the chamber 21 and be carried upwardly and outwardly between the flanges 15 and 19 into the flame, produced by the combustion of the vapor which is being generated from the upper and outer end of the wick 22,

til

It will be observed that the shoulder 20 is located beyond and overhangsthe upper end of the wick tube 7. As we now prefer to construct these parts, the shoulder 20 will overhang or project beyond the upper end of the wick tube 7 a distance equal to the gage of the metal, whereby the diameter of the interior oi the flange 20 is substantially equal to the outer diameter of the wick tube 7. i

With the parts constructed as illustrated and described, when the wick 22 is turned up the air distributor 12 will be carried upwardly on top ol the wick until such time as the shoulders 10 engage the spider arms 9. The inclined or wick engaging portion 19 of the flange tends to spread the top of the wick outwardly, as shown clearly in Fig. 2, but the spreading oi? the outer edge of the wick beyond said flange is prevented by means of the downwardly directed shoulder 20. Any irregularities, such as fuzz, on top of the wick will be compressed by the engagement oi' the wick against the flange 19 and will not be permitted to spread beyond said flange by reason of the shoulder 20. As a result, the exposed vapor-generating area of the wick will be constant,whereby it is possible to maintain constant the desired maximum flame, assuring uniform-- ity and reliability of operation. Furthermore, this result is accomplished in a par ticularly simple and inexpensive construction.

Having thus described our invention, what we claim is 1. in an oil burner, the combination of an inner and an outer wick tube, a wick therebetween, an air distributor comprising a sleeve projecting upwardly from about the upper end of the inner wick tube, a ring having a perforated portion projecting outwardly and upwardly from said sleeve to form therewith a space or chamber, such projecting portion having at its upper end a substantially flat or plane upwardly and outwardly projecting flange extending into a the path of the wick, and a second flange carried by said sleeve above the first men tioned flange and spaced therefrom, the sleeve being perforated between said flanges to permit the flow of air from the interlor of the burner to said space or chamber and throu h the passageway formed between said anges.

2. In an oil burner, the combination of an inner and an outer wick tube, a wick therebetween, and an air distributer commeant her, such projecting portion having at its upper end an upwardly and outwardly projecting flange extending into j the path of the such, and a second flange carried by said sleeve above the first mentioned flange and spaced therefrom, the sleeve being perforated between said flanges to permit the flow of air from the interior of the burner to said space or chamber and through the passageway formed between said flanges, the upwardly. and outwardly projecting flange being provided with a downwardly directed shoulder adapted to engage and confine the outer edge of the top of the wick therewithin.

3. ln'an oil burner, the combination of an inner and an outer wick tube, a wick therebetwecn, an air distributer comprising a sleeve pro ecting upwardly from about the upper end of the inner wick tube, a ring having a portion projecting outwardly and upwardly from said sleeve to form there with a space, or chamber, the projecting portion of the ring being provided with an upwardly and outwardly projecting flange extending into the path of the wick and said flange being provided with a downwardly directed shoulder, said shoulder projecting beyond the top of the outer wick tube.

t. In an oil burner, the combination of an inner and an outer wick tube, a wick therebetween, and an air distributor comprising a sleeve projecting upwardly from about the upper end of theinner wick tube, said distributor being provided with an out wardly projecting flange adapted to engage, and support the distributor on the top of, the wick, said flange being provided with a downwardly projecting shoulder adapted to confine the upper outer edge or the wick therewithin, the said shoulder being of greater diameter than the outer wick tube, whereby it overhangs the upper end of said wick tubeand limits the outward spreading of the top of the wick.

In testimony whereof, we hereunto aifix our signatures in the presence. of two witltltl lilo
