''o alt yw/'iom 'it may concern.'

lie it known that L EUGENE DERUNTZ, a citizen of the United States`r reaiding' at St. Louis, l`sii; s )u ri7 have invented a certain new and useful lmprovemei'it: in Oil-Buur ing Apparatus`r of which the followingV is a tnll, clear, and exact. deacription. anch aS will enable others skilled in the art to vvhich it appertains to make and use the Same.

This invention relate-.5` to apparatuses for burning oil.

The main obj-ect ot thc invention is to provide an eiicient. oihiiurninf; apparatuS which is so designed that thc oil will dow freely to a Steam nozzle from which a jet of perfectly dry Steam escaping. which jet ot steam atolnizes the eil and converts it Vinto a las that is suppiied to the coinhution chamber.

Another object of my invention is to pro vide an oiifonrning apparatna in which hoth the water heater and the `ineinliier in which the Steam is generated and raised to a high degree. of tennl/eraiiure vare exposed to the another object is to provide an oil-runningy apparatu which ia so designed that only a small quantity of hot Water iS Supplied to a Steaii1-genei,ati1ig meniher. thereby eualdinpr the apparatun to-hc started quickly and also very high degree.

Tinl figure ot' the drawing' is a vertical Sectional view ot an oildun'ning apparatua conatructed in accordance with my invention.

Re't'erringf te the terminen which iilustrate thc preferred form of my invention. A designates a Suitable Source of water Supply such, for example-r as a tank provided with an inlet pipe l and a ttoat valve Q for maintaining a constant level in the tank.

A supply tank communicates with a water boiler, conaiatino; ot a drum i and a tuhularrhaped member 6. which are ar ranged in the comlimation chamber l ot the aonaratu.y and a #team saper-heating nicmwhich may he in the torni ot a which in aim arranged in the coinhua aber, So that hoth ot #aid elements, nai'nel". the Water hoiler and the stemaV .itnfr mciiihers. are expo.

manner herein shown, a supply pipe 3 leading from the tank A to the drum 4. and the latter beingr provided at its top with a steam outlet pipe 5, leading `to the tubular shaped member 6, from which a pipe 7 leads hack to a riser 8,'eonnected Ato the `upper end of the water supply tank A. Thesteam super heating member may also be constructed in various ways, hut lf prefer the construction herein shown, on account ot' yitis; simplicity and eiicicncy, the pipe or' coil 9 being arranged in the combustion chamber and provided at one end with an outlet pipe l() that leads to a steam nozzle 11. 12 which communicates with the coposite end of the Steain-Superlieating member 9. is arranged inside of the tuhular-sliapeift niemher 6, and a needle valve 13 or other suitable device is provided for permitting a small quantity of steam to enter the coil t). view ot' the fact that the member f) ia comparativelyflai'ige and is supplied with a very small quantity of steam, the latter will he I quickly heated after it enters said i'neinher, tire in the combustion cliaml'ier. nd still and in passing through said meinher it wili he rained to a high degree of temperature so that it will loe dry when it emerges trom the upper'end ot saidmemher.

The oil is contained in a reservoir or tank il from which a Supplv pipe i5 leads to a causingr the steam to he heated quickly to a filtering devic(` consisting of a cylindricah Qhapcd casing iti having a tubular-Shaped Screen 17 arranged therein and provided adjacent its upper end with a laver of tiltcrine' material 19 the Supply pipe i5 having a vertically dispoaed branch i5 that pir-ciente dovi'mvardly through the top of the caaingr 1G and through the layer ci' filtering material 1S into the tubular-shaped Screen 17. An outlet pipe 19 leads from the upper cnd of the casingr i6 of the filtering device to a vertically dinposed pipe Q whose lower end tcrn'iinatea adjacent the steam nozzie il no as to cause the oil to drop downwardly in Front ot' Said steam nozzle and thun he :itemized and converted into gas by the jet of Q:team which constantly emerge@y from nliicli preferably consists ot a, large said steam nozzle. I prefer to provide the filtering; device with a removable bottoni wall Q1 so as to enable the sediment which collects: in said device to he removed, and also prefer to provide the oil-supply pipe if' Y ,d directly and the outlet pipe 19 from the filtering c in the commotion chamber. Said l device ivith valve?, l" and 19a, respectivelv.,

izoncif An inlet pipe i I v q I E iior controilinzirl the supply of oil to the nur' l pretcr to construct it in the i i@team nozzle 11 which is also provided with a controlling valve 11. To insure a steady and free flow of oil from the oil-supply tank 14 I have provided the apparatus with means for heating the oil in the tank 14, the means herein shown consisting of an extension 8 from the riser 8, through which steam passes upwardly through the tank 14 and fiows back through a return pipe 22 to the water tank A, said return pipe being preferably provided with a gage 23, and the riser 8 with a safety valve 24.'

The operation of the apparatus is as follows: A small quantity of oil is poured into the pan 25 that is arranged in the combustion chamber under the boiler and Within a few minutes steam is generated and flows into the member 9, where it is raised to a very high degree of temperature so that a jet of dry steam will emerge from the nozzle. The valve 19a is regulated so as to cause the oil to drop from the lower end of the'pipe 20, and, when said drops of oil come in Contact, with the jetof highly heated dry steam that emerges from the nozzle 11, the oil will be atomized and converted into a highly combustible gas which produces a very hot flame in the combustion chamber, the-Steam which circulates up through the riser 8a causing the oil in the tank 14 to become heated, and the filtering device that is arranged between said oil-supply tank and the oil'discharge pipe 20 causing ali of the dirt and foreign matter to be separated from the oil before it is mixed with the steam. In view of the fact that both the boiler 4 and the steam-superheating member 9 are exposed directly to the ame n the combustion chamber, the apparatus can be started quickly and the steam which is supplied to the steam nozzlell will be perfectly dry.

I do not wish it to be understood that my invention is limited to an apparatusof the exact construction herein shown, nor to an apparatus that comprises means for tilten ing and heating the oil before it is mixed with the jet of steam. It is desirable, however, to first heat the oil and filter it in the manner herein shown as this insures a oonstant and steady supply of fuel to the steam nozzle.

Having thus described my invention,what I claim as new and desire to secure by Letters Patent is:

In an oil-burning furnace, the combination with the combustion chamber and a burner therein comprising' steam and oil nozzles, of a drum connected to a sourcey of water supply and arranged in said chamber directly opposite to said burner, a boiler consistingr of a tubular menioer located above and connected to said drum, a pipe running longitudinally through said member and opening into the latter at one end. a valve to control the opening at the end of said pipe, and' a superheater connected to the other end of said pipe and to Said steam nozzle. l

VIn testimony whereof I hereunto affix my signature in the presence of two witnesses, this ninth day of March 1911.
