OIL-BURNER.

To all whom it: may concern:

Be it known that L-WILLIAM R. JEAVONS, a citizen of the United States, residing at Cleveland in the county of Cuyahoga and St-ate of (dhio, have invented a certain new and useful Improvement in Oil-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to burners for oil stoves, and more particularly to burners of the type wherein a bluefiame is produced from a wick without the provision of perforated oommingling tubes.

The general object of the invention is to promote the safety and efliciency of burners of the above type in particulars to be described hereinafter.

Generally speaking, the invention maybe defined as consistin of the combinations of elements embodied in the claims hereto annexed and illustrated, in one exemplification, in the drawings forming part hereof, wherein- Figure 1 represents a vertical sectional view taken through a burner constructed in accordance with my invention, certain parts being shown in elevation; and Fig. 2 represents detail. of the upper end of the burner showing the conditions which exist when the wick is in its most elevated position.

Describing the parts by reference numerals, 1 represents the'outer and 2 the inner wick tube of an oil burner 3 denotes the wickavithin said tubes, said wick being pro Jii'ledwith a carrier 4 adapted to be engaged by the star wheel 5 on an inclined shaft '6. Within the inner wick tube there is located a .centeringdevice for the spreader comprising an outer ring 7, an inner ring 8, and spider arms 9 connecting said rings.

10 denotes an upwardly projecting ring which is secured at its lower end to a por tion of the air deflector and forms within the inner wick tube an annular chamber 11. At its upper end, ring 10is provided with an inwardly-bent portion 12, forming an air barrier which extends above the inner wick tube, and said ring maybe provided with perforations 13 in the body portion thereof as well as in the flared portion lfi,

A spindle 14 is provided to which the upper ends of the spreader and airdeflector are secured, saidspindlo extending through the inner rin 8 'of the centerim device.

15 denotes a freely-perforated plate which extends across the bottom of the air deflector and carries the automatic locking device 16 which is adapted to engage the arms 8 in the manner shown and described in my lgzg pnt No. 875,913, issued November 19, 1

17 denotes the burner suppiy pipe to which the burner is connected by means of a hook l8 and an outwardly projecting connection 19 to which there. is applied a strap 20, in the manner shown, described and claimed in my application No. 462,775 filed i November 10, 1908. At its ends, the burner supply pipe is provided with a plug 21 which forms with the pipe a tight joint in the manner described and claimed in my aforesaid application. 7

22 denotes a drum which is carried by the lower end portion of a collar 23, which collar surrounds the upper end of the outer wick tube and is conveniently supported therefrom by means of projections 24 carried b the collar and engaging a ledge 25,

forms on the outer wick tube. It Wlll be observed that the collar 23 is contracted between the ends thereof, as shown at 20, and that it flares outwardly above and below such contracted port-ion, for the purpose of supplying air to the flame in an cfiicicut manner and particularly to prevent such vibrations of the flame as will cause a disagreeable humming, as set forth in my application No. 430,432 filed May 2nd, 1908. It

will be observed also that the upper end of the outer wick tube terminates at short dis tance below the most contracted portion of collar 26 and that the upper end of the'inner wick tube is considerably lower than the upper end of the outer wick tube-i It will also be observed from Fig. 1,,wheroiu the parts are shown in the positions which they occupy during the normal operation of my burner, with a full, bhiefiame, that the u per end of the wick normally projects to a out the height of the most contracted portion of the collar 23.

It frequently happens that persons operating stoves of the character shown herein 116 with the arms 5 lVhcu the wit-l; i-z

lighted rior to bringingthe same in contact .wit the spreader there is a' tendency for the .fiame ascending from the outer top edge of the wick to curl over on top of the spreader and heat the same, and this heat, being conducted downwardly to the wick tubes, i creases the vaporization from the airdistributer dis .-comprises a perforated support connected at its lower end to-the .rin 10 and servlng wick. e provision of apertures within the outer peripheryof the spreader tends to prevent this action, but-is not always adequate for the purposeg-especiallyg as vaporiza; tion is occurr ng on the inner exposed surface of the wickte supply the flame below the spreader and within the inner wick tube.

This interior flame also increases the vapoas a sup ort for two sprea ers. The lower end of t e su port is provided with a vertical flange 2 which is connected to the said rin 10 by fastenings 28. .Above the vertical ange, the support is provided with a frustd=con1calport1on 29 rovided with perforations 3Q for the free a mission: of air to the interior of thering 10 and the interior of the '11 per portion of the inner wick tube. vbove't e portion 29, the support is pro vided'with a vertical extension 31 and above such vertical extension 31 ,it is provided with another frusto-conical portion 32 provided with perforations 33. In the ring 10 and the top of the inner wick tube there is located an air deflector. The upper portion of this deflector comprises a spreader 34, havin its outer edge-or peripheryextending a ove theto -ofthe wick 3. The lower portion of t is deflector projects downwardly below the air barrier formed at shown in the drawings.

the top of the ring 10 and is connected with the vertical portion 31 of the support, as The outer edge of spreader 34 is preferably between the inner and the outer periphery of the wick'3.

, c 35 denotes an upper spreader which is secured to the top of the .air distributor by means of hollow rivets or eyelets 36 and is provided within its outer eriphery with erforations 35., The sprea er 35 is spaced mm 's reader 34 and preferably projects outwar ly ashort distance beyondthe edge .of the spreader 34, forming therewith a chamber 37 communicating at its inner end with the interior of the burner through the perforations 33 and adapted to dlscharge which endangers, the house or air from the interior of the burner into the flame produced at the wick. This chamber is of greater width at the inner or inlet end thereof than at the outer end.

' Under normal conditions, the burner will.

operate with the 'parts in the positions shown in Fig. 1. The up er edge of the wick will be located below t e outer edge of spreader 34 "and air will be directed into the flame below thespreader 34. The flame 38 will extend from the top and from the inner side of the wick, there being no flame at the outer surface of the wick, and a large proportion of the flame will pass belo'wthe spreader-34 and between the same and the wick. The-combustion at the inner surface of the wick is maintained by the supply of I air throu h perforations 30 into the space formed within the upper portion of the inner WiCK tube and below the spreader 34, the

air barrier preventing the flame from being swept away from'the inner surface of the wick.

When the wick is turned up to full height, as shown in; Fig. 2, the upper andinner edge of the wick engages the outer edge ofthe spreader 34. The'circulation of air into the chamber formed on the inside of, the

upper end of the wick is stopped, as the de- 'flector including that portion of the spreader 34 which projects inwardly from the top way isprovided or the upward escape of air from said chamber. It 1s, therefore, im-

possible for combustion of the vapors at the upper inner-end of the wick to existfor any appreciable length of time. Furthermore, as all the air from the interior of the burner now flows through the contracted passageway formed between the spreaders 34 and 35, this air impinges against the flame which extends from the outer top edge of the wick, and, if it does not blow out the flame, kee s it down to an extremely low height, as indicated at 3-9, in Fig. 2, the air flowing between the restricted portion of the collar 23 and the outer surface of the wick preventing the formation of flame at theouter surface of the wick at this time as well as during normal conditions. The height of the flame now is not only insufii cient to produce any harmful result but, on the'other hand, serves asa sort of pilot flame to light the burner when the operator turns the. wick down to normal position.

With the construction and arrangement of parts as illustrated and described herein, it will be impossible for an operator, in at tempting to' extinguish the burner by turning the wick up instead of down, to endanger the stove or the apartment within which the same may be lccated. This result is. secured in 'a-constructionwhich is exceedingly simple and which has proven to be of marked efficiency.
