Application filed Decembor`v27,`1920. Serial No. 433,338.

To all lwhom t muy concern:

Be itknown that l, lVILLL-iai MCARTHUR, a. citizen of t-he United States, residing'at T enino, in the county ot Thurston and State of llvashington. have invented a new and useful Burner, ot' which the Vfollowing is a speciiication.

This invention signed to use, as a fuel, a mixture of pulverized coal, peat or other fuel dust With alcohol or any other light oil.

One of the objects of the invention is to provide simple and efficient means for et-` tecting a proper mixture ot' the 'fuel ingredients before they are directed to the point or consumption, the mixing of the parts being controllable readily.

A further object is to provide apparatus of this character which can be made in various sizes and shapes so as to adapt the same for use with large or small boilers, with stoves, etc.

lith the foregoing and other objects in vienwhich will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that, within the scope ot what is claimed, changes in the precise embodiment of the invention shown can be made Without departing from the spirit of the invention.

In the accompanying drawings the preferred' forni ot' the .invent-ion has been shown.

In said drawings- Figure 1 is a view partly in front elevation and partly in section o'f the burner and the fuel mixing apparatus combined therewith. i

Figure 2 is a plan view.

Figure 3 is an enlarged section on line 3 3. Figure 1.

Referring to the figures by characters of reference 1 designates an oil container which can be of any desired configuration. As shown in Figure 2 this container is semicyliiulrical but it will be obvious that the same can be made in the forni ot three quarters oi a cylinder or can be otherwise shaped so as to properly fit upon or against av supporting structure. i.\,rranged within this container is a substantially conical holder 2 for finely connninuted fuel. this holder pretura-bly extending Jfrom the top relates to burners cle-- to the bottoni of the container 1v and have f ing its-small lovverend opening into an outlet tube 3- extendingbelow the bottom of the container 1. The top of -the holder, 2 can be provided with a removable cover 4: and a suit-able baile orspreader' can be supported in thelower'portion of the holder andv spacedl 'from the outlet tube by supporting legs 6.

'f Extending Afrom the outlet tube 3 yisl a the bottom ofthe containerl into the topL of the nozzle 2 andvis provided with a valve 11 whereby the flow ot oil from the container to the nozzle cany be controlled. @peiling into the closedl end of the tube 8 is a blast pipe 12 which terminates between said end and the nipple 7 and communicates with a tank 13 or the like for supplying air under pressure. used as shown a pressure gage 14 may be mounted thereon. A valve 15 is provided for controlling the flow of air through the pipe 12.

A valve 16 is mounted in the tube 3 and by means thereof the discharge of the comininuted material from the holder 2 can be controlled. An oil gage for indicating pressure can be connected to the lower portion of the container 1 as shown at 17. An oil supply pipe 18 opens into the upper portion of the container and has a controlling valve 19. A pressure gage 20 is oarried'by this pipe 18 for indicating air pressure.

In using the apparatus alcohol or other light oil is admitted under air pressure to the container 1 through the pipe 18. The pulverized coal or other combustible material is placed in the holder 2. The 'valve 15 is opened so that a jet of air will bedischarged longitudinally Within the receiving tube 8 and across the lower end of the nipple 7 `into the nozzle 9. Valves 16 and 11 are then opened Vdesired distances so as to secure the proper mixture of fuel. The dust discharged into the tube 8 will thus be blown into and through the nozzle Where it will be It a tank isl mixed with the oil discharged into the nozzle, it being,T understood that the air blast will break up the oil into a ne sprayv which ivill be inixed thoroughly With the fuel. Thus a highl)v Combustible fuel inixture will be delivered from the nozzle.

The baille serves to prevent the powdered fuel 'from choking the outlet tube lt will be seen that the apparatus is very simple. inexpensive and efficientand ean be .applied readily to stoves and the like.

lVhat is claimed is:

l. In an apparatus of the class described, a liquid fuel tank, an inverted cone-shaped powdered fuel compartment located in said tank with an aperture in its apex openingT through the bottom of the tank, said tank being in longitudinal alineinent and sup ported beloiv the bottom of the tank.

ln an apparatus of the class described, a liquid fuel tank having an inverted cone- .shaped holder arranged therein and extendinn' freni the top to the bottoni of the Itank with its apex provided With an opening extending' through said tank bottoni, an outlet tube leading' from said opening below the bottoni et tric tank, a removable cover at the upper end of said holder, a nipple leadinn` from said tube, a reeeivinfitube arranged in a plane at right angles to said nipple and through one side Wall of Whieh said nipple extends,y said receiving tube being open `at one end and closed at the other, a tapered nozzle extending from the open end of said tube beyond the Wall of the tank`4 a pipe eenneeting the tank with said nozzle in advance of the conneetion of said receiving tube7 and a, blast pipe openinginto the closed end of the receiving; tube and terminatinff between said end and said nipple,

In testimonyv that I claim the foregoing as inv oivn', l have hereto aiiixed iny signature in the presence of a. Witness.

lllituess P. C. lxnsn.
