To all whom it may concern.

Be it known that I, JOSEPH HEINZEL, citi-' zen of the United States, and residentof White Plains, in the countyof Westchester and State of New York, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification. j i g This invention relates to oil heaters, the particular object being to design a heater which uses oil or other liquid as a fuel and .is adapted to take the place of a coal -fire.

in the ordinary furnace, thereby eliminating coal as a fuel, and has numerous advantages such as no stoking, no cleaning of ashes and carting of the same, and no other duties'consequent to the use 6f coal, are required.

" Another object is to provide a heater in which the oil flame is drawn up by and combines with a steam vapor which is generated by the flame, and is adapted to hasten atomization of-the oil and increase the temperature of the flame.

Still another object is to provide in conjunction with the heater, float valve means similar to that of a carburetor, which at all times retains the fuel oil at a desired level, and, when failing to-operate, automatically closes the fuel supply hne.

These and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawings. v

' Referring briefly to the drawings, Figure 1 is a sectional elevational view of the heater and oil level control valve in operative position.

Figure 2 is a top plan view of the same,

Figure 3 is a sectional elevational view of a modified type of hood.

Describing the drawing in detail, the numeral 1 indicates a spherical bottomed pan which is mounted'on legs 2. A number of uprights are formed on the periphery of the pan, and have horizontal arms l projecting outwardly intermediate of their length. Said arms are adapted tosupport an annular shell 5 upon which an inverted hood 6 is formed, the latter having an opening 7 at its upper end. Said shell is mounted above the pan, the space 8 between both the members being provided for air circulation into the a over the an. A funnel -9 having a concavel form a 'walllO is mounted concentrically 1n the pan 1.

A water jacket 11 is supported above the opening .7 of the hood and has a liat horizontal surface 12 which forms a heating iron for the water content of said jacket The latter is supplied with water thru the pipe 13, and, as said contents are heated,

the vapor rises to the head and is carried ofl thru the steam pipe 14. This steam lead 7 courses downwardly to a position beneath the pan where it communicates with a condenser chamber 15. Saidchamber has an upper pipe 16 and lower pipe 17 connected thereto which extend horizontally there from. The upper pipe has a nozzle or jet mounted on a valve 18 which is directly below said funnel. The nozzle of the valve extends upwardly and partly into the funnel. A relatively long stem 19 having-a small hand wheel 20 at its end opens or closesv said nozzle valve as desired. The lower pipe 17 a as stated communicates "with the lower end of the condenser chamber 15 and leads any of the condensed vapor out of the-line thru the valve 21.

'A fuel control valve which may be installed at any desired distance from the heater comprises an oblong casingfl22 and has a sleeve 23 which projects downwardly within the chamber forming a' guard for a stem 24 which has a hand wheel 25 at .its

upper end. A similar sleeve aligned with the aforesaid member 23 projects upwardly from the bottom of the casing, and has a tapered surface at its upper -end which is adapted to seat the valve head 27, the lat ter being fixed to the lowerend' of the stem 24. A fuel ,delivery pipe 28 is connected to the lower end of the sleeve 26 and passes to the pan 1 at a level slightly belowthe upper edge of the latter. l

An annular float 29 encircles the upper sleeve 23, and has a fulcrumed lever bar 30' 37. at its lower end, said bucket being guarded within a housing 38. An overflow tube 39 connects the casin 22 with housing 38 and leads the excess oi from the casinginto the bucket 37.

Figure 3 shows a modified type of water heater in which the water jacket'comprises an elongated tank 40 which encircles the interior upper surface of the hood 6, the water being fed in thru the pipe 41 and out thru the pipe 42. This type of heater may be preferably used within a furnace .and as stated does away with coal and its resultant attention. By removing'the furnace grate the pan may be slipped into place thereim and allowed to stand on the floor, the legs 2 keeping the an approximately on a level willheat the water jacket 11.

with the fire oor.

The hood is then placed in position and .the water jacket 11 is filled. By opening .the valve 34 the liquid will pass into the casing 22, and thru the pipe 28 to the pan 1, the level of the oil always being kept at the level shown, by the float 29. The surface of the oil in the pan is then ignited and the flamesand heat emanating therefrom The steam which is released from the heated water passes thru the pipe 14 into the chamber 15. As the pipe 14 is cold when the first volume of. steam passes therethru, the latter will be condensed and may be led out of the line thru the lead 17. The steam which does not condense will pass into the'pipe 16 and will blow out thru the nozzle valve 18." As the steam rises thru the funnel in a strong draft it drail vs up and readily atomizes the burnin 01 he greater volume of vapor will be dif-j fused over the surface of the oil in the region about the funnel 9 because the draft is there at its maximum. Obviously, the intensity of the draft caused by the steam jet, will diminish in all radial directions toward the periphery of the an, and will be a minimum at said perip ery. Consequently, .the rate of vaporizatlon of the oil will-be highest about the funnel 9 and will be proportionately less at. a distance from the funnel. This is compensated for by the substantially spherical shape of the pan 1, the central portion having the greatest depth of liquid and the depth of oil at the edge of the pan being relatively shallow, thus permit= ting the oil in the latter region to be more readily and rapidly heatedl. A heater using oil as a fuel and comprising an annular dished pan adapted to be flooded with oil,;a concavely walled funnel passing concentrically thru said pan, a

conical hood mounted over said pan, a water acket above said hood, the watercontent being, heated and changed to vapor outlet pipe connected to said jacket having a nozzle valve at its opposite end, said valve when opened being adapted to pass said steam thru the funnel and over the pan, said steam being mixed with the oil flame to aid atomization of the oil, and means for leading oil into said pan.

2. A heater using oil as a fuel and comprising an annular dished pan adapted to be flooded with oil, an upright funnel passing concentrically thru said pan and having its upper and lower openings of equal diameter and tapering inward to a reduced central throat, a hood mounted over said pan, :1 water jacket above said hood, a steam outlet pipe connected'to said jacket and having a nozzle valve at its opposite end, said valve when opened being adapted to pass said steam thru .the funnel and over the pan, said steam being mixed with the oil flame to aid -with oil, horizontal arms extending radially outward from the periphery of said pan, a conical hood, the latter being adapted to be supported by said arms above the pan and outside the periphery of the pan, a water jacket above said hood, a funnel in said pan, a steam outlet pipe connected to said jacket and having a nozzle valve at its opposite end, said valve when opened being adapted to pass said steam thru the funnel and over the pan, said steam being mixed with the oil flame to aid atomization of the oil, the heat from said burning oil being adapted to pass upwardly thru the hood and heat the contents of the jacket.

4. A heater using oil as a fuel and comprising an annular spherical surfaced pan, an upright funnel passing concentrically thru said pan, said an adapted to receive fuel oil, the depth of said oil being greater in the region of the funnel, a hood mounted over said pan, a water jacket above said hood, a steam outlet pipe connected to the posite end, said nozzle valve communicating with the funnel opening, said steam in assing upwardly from said nozzle bein a apted to be difi'used over the surface. 0 the oil in the pan and aid in atomization of the oil, the oil at the pan being more rapidly heated due to its lesser de th in that region.
