Inrsovsmsnrln 'LAMPsuRNsns `B e it vkno wn that I, L. MAncY, of Newport,Newport county; State ofltbcde Island, have inventada new and useful Improvomentin Lamp-Burners und I do hereby declare that thelollowing is a full, clear, und

exact description thereof, which will enable others skilledriirltbe nrt tomukeondluse the'same, reference being had to the accompanying drwings, forming part o'f this specification, in' whichl' Figure 1 repi'eseuts a central vertical section through the"burner.

Figure 2 represents a. similei: section atright angles to that of iig'. v1. Similar letters of rfer'errcefindicato lilgepaits I Y The object of this invention is to obtain increased illuminative power from double wicks, and is intended for burning kerosene-oil. I l

' It consists in the formaiiionaud arrangement of the parts, as set-forth in th'elfollowing. The part E, holding the 'wick-tubes a a, is divided into anupper and-lower chtmber, A und B respectively,

which aro formed by the diaphragm e e, tl xrongh which tho.atwiek tubes a a pnss=.\ The nir enters through the laternl vperfor-ations of4 both chambers, and fthe nir from the lower chamber passes upward between the wick-l wtnbes; thrcugh tbe opehings'fl, audsupplies the inner sides of the ilsme.

coed between the wick-tubes 'und nbove `the opetiing, us show'nyand serves to bre-ck` the upward current c By my invention, thefemployment of a. tube, passing 'dmv -is obvinted. v

"are the spur-wheels for elevating the wicks, and nre of ,the usual construction.

Y The part E E is uixed to thepart D D, which latter may be formed with 'a s`orew-thread or other suitable device fortting the lumps now in use.

"'lhe bottom ofthelower chamber is showunt c. l

The plate b extends'ncross the chamber A, and is lbent, asfshown, for the purpose of giving a greater perfornted surface. I, 4 l i Y l s The csp,'-C, isremo'vcblo, it merely'resting within theanged ri't of the part E E, as shown.

This oo p or cone contains an important feature of improvement, and one which ,is the result of much experimental trial, for the, purpose of obtaining thepcrfoct combustion of tiro flat wickswitbin the some oo ne. The invention consists in forming the cone with two obruptshoulders, gg, obtained by swngingthe 'conc at the ends of the vopening in the sume, so u s to form a horizontal surface at ouch ond of the opening, as is more distinctly shown st iig. 2.

The function of' these shoulders is to.del1ect tbe upward current of air'ct these points,` therebyactuating it in two currents between the proximate snrfacesof the iinme's-- A The currents thus thrown in between the dames meet encb'hther, and again react outward, thus spreading -ench dame in a fan-shaped blaze, and'obtsining an increasedsurface of the sume, whereby their proximate surfaces are completely oxidized bythe d eected luternl currents, sind also by tho central current from below, and 'au increased brilliancy is the result.

I um owure that s nu'mber of doublewickburners hnve been-mudo, some of which remotely resemble the* one described, but the points ot' dili`erence' above shown Anrc the result of repeated experimental trials 'to produce a perfctly-operctingdouble-wickedburncr for hydrocarbons, as such n one was not found by n ie in my .experiments with those previously, patented.

' Having thus described my invention, I claim ss new. anddesire to secure by Letters Patent- 1. The arched perforated plateb, arranged "between the wick-tubes, whereby the upwardcurrent of air from tho chamber B ,is broken, to prevent the formation oteddios when it encounters tho lateral current which enters -through theperforntions inthe upper chamber A, 'as herein shown und described.

2. The csp o r cone C, when formed witb'two abrupt lateral shoulders, g g, substantially as described, and for the purpose set forth. Y. The v:beve specification of my invention signed by me, this 10th day of Mcrob,1868.
