LAMP HEATER.

l.Application led ctober 9, 1924.. Serial No. 742,679.

To all whom t may concern:

Be it known that I, JOHN M.

a citizen of the United States, residing at Elmira, in the county of Ghemung and State of New York, have invented certain new and useful Improvements in Lamp Heaters, of

which the following is a specication, reference being had to the accompanying drawmers.

a'.lhis invention relates to lamp burners, and more particularly to a lamp burner especially adapted for use in conjunction with brooder heaters such as shown 1n m co-pending applications, Serial Nos. 691,- 232 and 707,712, filed February 7, 1924 and April 19, 1924, respectively, of which later application this application is a continuation in part. v

An important object of the invention is to provide in a round wick burner a llame spreader steadying the flame from the wick and spreading the same so that a flame similar to that produced by a lflat wick is" provided and smoke from this ame, when the wick is turned up, is eliminated unless, of course, it is turned up to an unreasonable extent.

A still further obj ect of the invention is to provide a lamp burner, the parts of which are readily assembled and disassembled, thus permitting the burner to be frequently cleansed, as is necessary when the burner is employed in conjunction with a brooder, incubator or the like. Y

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, and wherein Figure 1 is a perspective of the lower end of the chimney of a lamp burner constructed in accordance with my invention;

Figure 2 is a Aperspective of the flame spreader; l

Figure 3. is a perspective of theburner dome;

Figure 4 is a perspective of the burner dome support;

Figure 5 is a. vertical sectional view through the assemblage;

Figure 6 is a vertical sectional view to that shown in Figure 5 and taken through SARGEANT,

' extends a horizontal the burner dome and upper end of the wick tube and iiame spreader.

Referring now more particularly to the drawings, the numeral 10 indicates a burner neck threaded at its lower end, as at 11, for engagement in the filling opening of the fuel reservoir and having extending upwardly therefrom centrally thereof a circular wick tube 12. This neck is provided with the usual adjusting element 13, by means of which the wick 14 contained within the tube may be raised and lowered. 'This means being old and well known, it is not herein illustrated other than by showing the operating shaft thereof. I f i 1 Extending upwardly from the sides of the burner neck and secured thereto is aA circular burner dome support 15 having straight side walls provided with, circumferentially spaced openings 16, by means `of which air may lbe admitted to the interior of the support about the wick tube 12 whichV the support surrounds. The upper edge of this wall is provided with circumferentially spaced, segmental, horizontally and outwardly directed flanges 17, the purpose of which will present-V ly appear.

The burner dome proper 18 is of the usual construction, with the exceptionof the fact that the slot 19 thereof is 'widened at its lower end and extends downwardly into the side wallsof the dome, this widening of the slot being indicated at of the widened portions of the slot are provided in alignment with the slot 19 with V- shaped notches' 21, the purpose of which will hereinafter appear.

From the lower edge of the burner dome flange 22 provided with circumferentia-lly spaced openings 23 to permit the passage of air. The edge of this flange is provided with a plurality of downward extensions 24 corresponding in number and arrangement to the flanges 17 of the burner dome support 15. The lower ends of the extensions -are provided with inwardly directed portions 25 having their inner edges arranged upon a circumference equal to the outer diameter of the burner dome support and the extensions themselves being of a width slightly less than the distance between adjacent edges Of the flanges 17.

20. The lower walls By applying the burner dome to the upper surface of the support so that these extensions engage between the flanges'17 and then giving the same a partial rotation, the inwardly directed .portions 25 ,j underlie 1 the flanges 17, upon the upper surface of which the flange 22 is at rest, thus preventing displacement of the burner dome, etween the downward extensions V221 the edges of the flange 22 are provided with upward extensions 26, the upper edges of which are formed with inwardly extending portions 27 adapted to receive segmental flanges 28 formed 4upon 'the lower end of 'a chimney 30 and corresponding in structure to the flanges 1"?` of `the"bur'ner' don'ie support 15. Thus the burner dome provides 'means not only for attaching the burner dome to the burner dome support but also means for vatt'aching the 'chimney to the burner do'm'e,

Mounted 'ulpon 'the upper jend of 'the wick tube is a short 'sleeve 432 having extending outwardlypand upwardly therefrom at opposite sides thereof a pair of wings 33 which rest in the lower ends 'of `the slot. These wings, in addition 'to inclining upwardly and outwardly, are V-'shaped 'incrosssection.'` Extending outwardly at rig-ht 'angles :to the wings `33 are a pair of flanges 34which extend into proximity with the walls of "the dome and direct lair passing upwardly through the donne against the inner wall of the dome by which it is directed in leaving 'the overhanging lips 35 of the Vdome substantially horizontally against the flame arising from the wick 20. The structure 32, 33, 34; combines a. flame spreader in combination with a `circular wickand will form a flat narrow band ofvflame such as is ora flat wick. that a burner of this character mayy be very -cheaply and readily produced and is readily disassembled for cleansing, 'thus rendering less likely neglect of the burner, which often results in fire or sinokingburners which have disastrous effects on the Acontents of vthe broeder or incubator.

It will be obvious that the device as above described is capable of a considerable range of' change and mpdilication without materially departing fromvthe spirit of my invention andy I accordingly 'd oA not limit myself to such specific struct-'ure except 'as hereinafter claimed.

I claim v 1. In combination with a burner domey having.l a slot-in its upper end vand extending transversely thereof, 'the ufp'pe'r wall of they dome forming-at 'the sidesof the 'slot 'inwardly directed barile walls, aI 'tubular wick holder projecting axiallyinto the low'e'i` Eend of the burner dome, and a flame :spreader removably engaged with the upper 'end of the wick holder, comprising a sleeve endinarily provided by It will be obvious.

, wick holder projecting ay gaging the wick holder having diametrically opposed, upwardly and outwardly inclining wings V-shaped in cross section, said sleeve being provided at right angles to said wings with outwardly extending horizontal flanges directed toward the adjacent walls of the dome and directing air against such walls i in passagev upwardly thereagainst whereby said air engages against the flame 'abovethe horizontal ballles of the burner dome to spread the flame from a wick contained wit-hin said wick tube.

2. The combination with a burner dome having a slot in its upper end extending transversely thereof, the upper wall of the dome forming at the 4sides of the slot inwardly directed baflle walls constricting the slot at its upper end, the lower walls of the slot having V-'shaped notches therein, a tubular i ia'll'y inte the lower end of the burner dome, 'and 'a flame spreader removably engaged Ywith the upper end of the wick holder comprising a sleeve engaging the wick holder having diametricallyopposed, upwardly and outwardly inclining wings V-'shapre'ldvin cross section, the ends of said wings extendinginto and having their lower surfaces fitting against .the walls of the notches at 'the lower ends of the slot.
