Appli-:ration led Octoberl, 1909. Serial No. 523,159.

To dll 'whom it may concer/n.:

Be it known that JOHN Bassinet, a

citi-zen ot' the United States, residing' at Frederick-'in the county ot Tillman and State or Cillahoma, have invented certain new and useful Improvements in Crude-@il Burners; and I do hereby declare the follow` orin a heating store and which may be re;

ing to be a full, clear, and enact description of the intention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to liquid fuel burners designed for burning crude oil. y

lt. has for its objects, among others, to simplify `the., construction of this class of burners,` to reduce the cost of manufacture thereof, and to product` such a burner which may be used with equal success in a cooking ily and quickly applied to either oi these types of stoves by the substitution of a pan ot' the burner for tl' grate and a special construction of lid pporting the feeding mechanism ofthe burner for the top lid ot the stove.

Another and very importantl object is to produee a burner which will have the maxi mum heating capacity at the sinallest possible cost for fuel and maintenance. In other words, is xny airn to place on the market a crudeoil burner which cannot become clogged up oi' get outof repair in any of the other 'various Ways which have been found so objectionable in .this type of burner. v

The invention contemplates the substitution for the grate of a stove of a pan in which there is placed a'- table having a crown.-

shaped or convex top and situated immediately below a vertically disposed tube supported from the top or cover plate ot' the stove. The stove should beentirely closed -or imperforate exceptv at the outlet leading to the chimney whereby the 4'only passage for -the ingress nf air is through said vertical tube.

right. tube is flared or tapered, being larger at the top than at the bottom. A draft of cold air down said tube is caused by its shape and tact that there are no open ings in 'the base or body of thevstoe.

rEhe invention also consists in the toutin'es of construction and oouibinz 'ions ot partsheineinafter described andl spec. red in. the

claims.

Fig'. 2 is a vertical sectional rie-W through the tire box oi a cooking stove or range illustrating; hou' my burner is applied thereto. an enlarged detailed view of the burner, and itin.

more particularly to the draw- For the ordinary top lid, I substitute. a lid 5 having a round opening G therein Etin/.nigh which is passed 'the tapered tube 7.- Said tube' is provided with a' projectinvflange 7 near its upper edge which rests upon the top of said lid and supports the tube in proper position. Below the lower end of said tube, 4there is placed a. crown-shaped table S raised from the bottom of the pan on legs t) to prevent the transmission ot' heat iti-oni one to the other. ln order to adapt. the tube to stoves of different heights, I provide a sleeve l0 fittedv to slide around the lower end ot said tube and haring snort legs or supports l1 which rest upon theto of the table leares the casing oit a well known l ing a space ofsuitable sizeV between the lower extremity of .sa-id sleeve and the table for the particles yof oil to pass into the pan.

Vithin the upper and larger end ot the tapered tube, I lforni a cross bar l2 arranged dianietrically thereof and provided with an opening in its center through which vthe end of the oil supply pipe 13 is passed. A ring let is screwed on to the extremity of said pipe 13 and froinsaid ring depend two converti-in flat stri )s of metal. One of these s g l l strips 15 extends some through vthe center of the distance down tube and is bent into spiral shape, as at 152i The other .strip l terminates near the upper end' r of the f rstrstrip leaving an opening between them below thecenter of said ring through'which the oil comin from thesupply pipe is fed.

The' oilthen ollowsthe coils laof the strip and finally drops from the lower extrem it of said strip upon the center `of Athe --ta le 8. I.

H I preferably A.place a sigxht gag-e 17 at some convenient point in t Said gage vis closed but provided with glass sides through which the dropping of the yoil may be'observed. The flow ofthe oil may be regulated by the valve I8 arranged justl 4 above the gagle. 'eater is applied to a cooking WhenI 'my stove or range, as illustrated in Fig:-v 2, the

pan .3 is made generally rectangular m shape; to fit the fire box 19. The top 20 of I ,the 4stove is formed with an. opening 21 to receive the tapered tubel 7", which Ain this case is somewhat reduced in length but still projects quite a distance above the top of the stove; `The projecting ring or flange 7b is located farther down the tube than in the previously -described application of the inventionvso as to 'support the ,lower 'end of said tube the proper distance above the the feeding strip are correspondingly shortened so that its/lower end is spaced the same' distance from the table as Lthe strip l5, pre- -gviously described.

- '..When the tapered tube is shortened, the spirals or. coils 15b of thattlie 'crown shapeof the table 8 greatly increases the lspreading 'of -the particles of oil thusv aiding combus- It will be noted tion and producing a better and hotterfire.

The use ofthe spiral or coiled feeding strip is designed to reduce'the friction of theair upon the drops of oil as they pass down said lower end of strip, so that when each dro leaves .the

eater force upbn the table with the result' N that it will be separated into very small 'and easily combustible particlesiwhereby a per- -fect'comb'ustion is obtained without the accumulation of soot. The diiiiculty in former crude oil burners has been to feedS-thefroil with suicient force to cause Ait to scatter. or

Aburner fit different forms and sizes ofjtoves, as suggested by the two applications of the invention which I have herein shown and tothe exact constructions illustrated herein,

therein as mayT fairly fall within ythe scope ofthe appen ed claims.

The following claims do not 'cover all of the patentable, eatures of my invention as hereinbefore described, yone branch of the 'invention being made the 'subject matter of a `divisional application 'which is to be filed before the presentv case goes to issue.

I claim zported with' its lower end above said pan,

end of said tube, and t'wo strips secured to tending downward. in converging lines, one of said'l strips formed into a spiral coil adapted'to feed the .oil from said pipe and' drop/it 'into the pan, the other strip terminating near to the first strip but spaced/away from it leaving an supply pipe. l .{In'rtestiinony whereof, I `affix my, signature;`"iii presence o f two witnesses.
