Application filed November 14, 1923. Serial No. 674,730.

To all when?, 'it may concern:

Be it known that I, l'lnNJAMiN l?. Minne, a citizen of the United States, residing at Sioux City, in the county of lVoodbury and ccitate et Iowa, have invented new and useitul mprovenients in @il Burners, ot which the following is a specification.

This invention relates to liquid fuel burners, and has for its object the provision of a novel burner ior utilizing oil as a fuel, the burner being adapted for use in connection with heating er cooking stoves, heating plants7 steam generators and the like, there being no restriction whatever as to the field of utility or the size whch may naturally be varied to suit the requirements of the service desired.

An important object is the provision oi a burner which is provided with priming means for .initially heating the Yfuel to ei!- iiect vaporization thereof so that it will be easily combustible7 means being also provided lor supplying the proper adminture of air to insure thorough combustion.

An additional object is the provision of a device ott this character which will be sinrple and linexpensive to manufacture, easy to install, positive in action, etlicient and durable in service and a general improvement in the art.

llVith the above and other objects and advantages in view the invention consists in the details oi construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation ot the device showing it embedded within an ash pit,

Figure 2 is a longitudinal section through the device alone in slightly spaced relation thereto,

Figure 3 is a plan view of the burner with the top element thereof removed.

teterring more particularly to the draw-n ings the numeral designates a uel conducting pipe upon the upper end ot which is mounted my burner structure nwhich includes a disk 11 having a hub 12 surrounding a central threaded bore 13 which is screwed ontothe pipe 10. This disk has an upstanding peripheral ilange 14 so as to Told a small quantity of oil and to serve as a priming pan. Above the disk 11 is the burner proper which comprises a disk 15 having a hub 1G formed with a threaded recess 17 screwed onto the upper end of the pipe 10. At its center the disk is provided with a small hole 18 which coinn'iuuicates with the recess therein and which is for the outlet ot fuel. The top surface ot the disk 15 is formed with a plurality or concentric grooves 19 so as to increase the active surface to the inaximun'i. rthe burner further includes an upper disk 20 which nts upon thedisk 15 and which is held thereon by a plurality of lugs 21 formed upon the disk 20 and projecting over the edge ot the disk 15. This upper disk 2O is concaved on its underside so as to define a space 22 above the top surface ci the disk 15.

The device is intended to be mounted within the ash pit of a stove, furnace or the like or upon the grate but in any event l provide a cylindrical sleeve 28 which is disposed about the pipe below the disk 11 and which is embedded for the greater portion oit its height in a mass 2li or ashes or the like so as to prevent air from entering at any place other than through openings. at the upper edge or' the sleeve.

Assuming that the device has been 'constructed, assembled and installed as above indicated, it will be apparent that to eiiect starting, a certain amount of oil is poured into or allowed to flow onto the disk 11 which constitutes the priming pan and this oil is ignited so that it will burn and heat the entire device very thoroughly. l/Vhen the oil is then turned on it will issue from the hole 18 and tlow onto the disk 15 which has been heated` by the flame rising from the priming pan and this heat will operate to vaporize the oil so that it will 'issue from the slight space between the disks 15 and 2O and burn to produce a sheet like flame. The air entering through the openings 25 gives the proper amount ot oxygen to insure proper combustion.

From' the 'foregoing description and a study oi' the drawings it will be apparent that I have thus provided a simple, inexpensive and easily installed burner which will be highly eiiicient for the purpose specified and also for all kindred and analogous purposes and which on account of its simplicity and tewness oi' parts is not likely to get out et order.

While I have shown and described the preferred embodiment oi my invention it is of course to be understood that 1' reserve the right to make such changes in the form, construction and arrangement of lparts as will `not depart from the spirit/,0f the inythe top surface of said disk being `formed l0 ventionprf'the scope of the subjOinedclaim. with concentric lgrooves for increasing the Having thus described my invention I aree and providing oil retaining means, :L

claim: dished inverted disk mounted above the first 5 A burner comprising a pipe adapted to named disk, and a sleeve beneath the primhave fuel pass therethrough, a priming. ,pen ingpan having its upper edge formed with l5 screwed onto the pipe, a disk carried bythe openings for the inlet of air. pipe above the priming pall .and having ,a In testimony WhereoI affix my signature. central hole lcommunicating with the pipe, BENJAMIN F.
