This invention relates to oil stoves in which is a burner adapted to utilize hydrocarbon fuel for generating the heat, and the invention-consists in certain novel details of construction and arrangement of parts, all of which will be specifically referred to hereinafter, reference being had to the accompanying drawings, in which:

1 Fig. 1 is a perspective. view, partly broken away, of an oil st-O-Ve constructed in accordance with my invention. Y b

Fig. 2 is a horizontal Sectional view through the same, with the radiants removed.

Fig. 3 is a vertical, transverse, sectional view, partly in elevation, through the stove.

Fig. 4 is a detail perspective view, partly broken away, of an improved oil burner, and

Fig. 5 is a longitudinal, sectional view through the vapor generator.

In carrying out the invention I prefer to provide a substantially rectangular stove casing havin ends 1 and2 connected by a top 3 and a. Eack panel 4. The front panel 5 extends from the bottom ofsaid stove a short distance toward the top to provide a heat discharging space 6 above the same, which co-operates with the hood 7 to permit the heat to pass out intothe room, there being a heat reflector plate S infthe rear of the space 6, which carries a transverse heat deflecting baflie 9 at its upper end, provided with an opening 10, through which the productsof combustion may pass inorder to exhaust through the discharge flue 11, which maybe connected by a suitable pipe to the chimney. I

y The front panel 5 is provided with vent openings-formed by louvers 12, if desired.

Supported in the bottom of the stove cas} ing is a fuel tank 1 3,which may be provided with a filler tube 14 and the tank is also provided with an air inlet port shown as a tube 15, through which air may be forced to provide the necessary pressure on the fuel in the tank 13. I prefer to provide the tube 15 permanently with a pump 16 of appropriate construction so t at the pump will always be available to increase the pressure in the tank to the desired degree. Leading fromthe tank 13 is a discharge pipe 17, which is connected to a T-fitting 18, comprisin a valve casing in which is a valve operated om the valve stem 19, extending Application through the end 2 and provided with a wheel 20 whereby the valve can be turned to vary the port area of the valve in the casing 18, which discharges into the gen-' erator 21.

The generator (see Fig. 5) is shown as comprising a tube or pipe, in one end of which is a ported plug 22, having a threaded end 23to engage the end of thepipe and having a tapered, threaded nipple 24 to be screwed into one end of thefcasing 18. The p1pe rovid ed at its opposite end with a screw p ug 25, which has a threaded end 26 to engage corresponding threads in the end of the'pipeand the plug is provided with a.

constricted discharge orifice 27 which discharges into the mixing chamber of the burner to be referred to hereinafter. I

Within the pipe is a filter 28, shown as consisting of a tubular fibrous envelope surrounding a core 29 and having its ends closed over the core, as clearly shown in Fig. 5. The filter is adjacent the plug 22 and between it and a heat distributing or radiating member 31 is a. strainer 30. The heat radiating member is shown as comprising a twisted ribbon or blade of metal having ood heat conductivity so that the heat applied to the end of the tube surrounding the member 31 will be conducted to the fuel passing through the tube, it being understood that the filter is at one endof the tube, the heat radiating member at the other end, and the strainer between them..

By dividing the tube or generator21 into a filtering chamber on one side of the strainer 30 and into a vapor generating chamber on the other side of the strainer 30, I am'enabled to provide a novel, inexpensive form of generator having certain advantages over known types of generators.

For example, in the present construction, the

filter is to one side of the heat zone so that it will not be subjected to intense heat from the source of heat which vaporizes the oil. In other words, the filter, which is generally which the zone about the ribbon 31 is sub jected.

The plugs 22 and 25 may have polygonal of asbestos, will not be subjected to intense or hexagonal portions 32 and-33 intermediate their ends to receive a wrench so that they may be screwed into position. The'plughas-a projecting endy 34, in which the v orifice 27; is located so that said end of the generator tube can be supported by a bracket and discharge into the mixing chamber of the burner. p p

The burner is best showninFig. 4 as com-- prising an elongated, rectangular, hollow casting 35, from the front face of which project brackets 36 and 37jbetween which 15 provided a priming pan 38. The brackets 36and '37 are provided with orifices 39 and 40 in horizontal alignment so that the vaporizer21 may be supp'orted therei'n.

The vaporizer rests upon thebottom edge of the orifice 40 with, the end 34 in the orifice 39 so that the portion'to one side" of the screen which carries the ribbon 31 is over the priming pan 38, the filter being entirely outsidethe heat zone," as'heretofore explained, The mixing chamber has an air inlet opening 42,'adjace1 1t the opening 39 so that: v he[discharged vaporized fuelpassing fromthe' orifice 27 maycombine with the air and mix in-the chamber 41, preparatory :to passing into the hollow: casting 35. The top of the casting 35 is provided Withfuel discharge openings 43, inwhich may be located removable disks having fuel openings, and prefer to use the well known lava disks, as'indica-ted at 44, which may be removed to be cleaned or for substitution. In the. front side of the member 35. and between the, brackets 36 and 37 are jfcorrespending disks having fuel openings to direct a flame against the portion 46, of the vaporizer surrounding theribbon 31 so that .ifthe burner is operating, allfof the fuel passing through the tube 21 will befsubjected; ,to heatfrom the fuelpassing through the orifices in the disks 45 so that a continuous vaporization of the fuelwill be .pro-

Yided-before it. combines withft'he: air with- ,inthemixing chamber'4L, j

e In order that the: burner may be inex'pen sively made, I prefer to'cast, the member 35, the brackets 86 and 37, the pan 38 and the fuel mixer 41in a single piece or casting,

thereby minimizing the'cost of production,

I andiit is an importantfeature of my inven- V passes through the vaporizer 21 and afi'ordtion to arrange the burner in substantially the manner shown, as it is'quite a convenient construction to make, providing eflicient vaporization of the hydrocarbon fuel as it i-ng' efficient mixing; with the air entering through the orifice 42 before it is allowed to "enter the hollow. castingmember 35-, preparatory'to being ignited.

It: will be apparent that the generator can be applied to the burner in a completely assembled position by introducing theen'd 34 into the orifice 39, allowing the generat ing tube 21 to he upon as bottom 11 01? the that all of the partswill be assembled.

When the tank is filled and there is suflicint air pressure onthe body of liquid, the priming pan 38 may receive a priming fluid such as alcohol, gasoline or the like, which may be ignited to heat the barrel of the generator or tube 21. When the valve stem 19 can be operated e through the medium ofthe handle 20 to unseat the valve slightly toallow the fuel to pass through the generator and when it reaches the portion 46, it Will'be vaporized. or gasified so that; it will'combine readily with the air entering' the inlet 42. The mixture may their be ignited as it passes. through the openings in the burner disks 44 and 45L When the fluid in the priming pan 38. has been consumed,

the burner will supply its'o'wn heat energy throughthe openings in the disks 45 to the v generator 21 so that the incoming fuel will be continuously vaporized or gasified as long as the burner is bein nsed. I

v I find it' articulai iyfadvantageous'to'. use radiant units in connection with the burner. These may consist of upstanding strips or grids 47 havin Y on their front aces and directed toward the spaced grids 49' on said units: The grids 49 are preferably in front of the burner orifices while the, grids '47 are preferably in rear so that the ignited fuel; passes between them points or protuberances 48 in, a; thin sheet-,, heatingthe projections 48 to. incandesence, and'raisin'gthe. tempera.- ture'ofthe fuel so vt hat a very hot flame is provided, the, radiant; sect-ions being assisted by the reflector 8 in radiating the heat through the opening 6..

' It is an: important feature of my" in en tion. that the protuberances 48will be heated to an intense heat, practically to: incandescenee. so' that the gases discharging from the burner ti'ps will have th irtempe r raised sufliciently to cause them to be 1c 1 combustible... Therefore, the gasesw havenot' been consumed 'na-rfthe base of the burner. will. be consumed within them-- di'ant' sections, on account" of the high tem. perature tov which they are raisechfso that practically erfect combustion takeslplap'e and the li'aility offunconsum'edtgases' escapinginto the. room will be reduced tot a minimum, if'not wholly eliminated, v.

The radiant sections combined with the burner provide a structure, of considerable importance in. oil burning: stoves; because some of the less volatile constituents offt'he vaporizedpil; must be, heated to a; very high temperature v before they can consumed. So. far] as I am aware, the application of meansfor superheating the heavier h carbons after they have passedthrough the burner tips so as to render them combustible is new as applied to oil burning stoves.

For the sake of the esthetic value of the device as well as to act as a guard or protector, I hinge at the edge ofthe front panel a guard 50, Which has an upwardly inclined portion 51 and a lateral ledge or shelf 52, the latter carrying a fender 53, which may consist of wire: or other suitable material. The entire guard comprising the member 50 and the fender 53 may be swung outwardly, as shown in Fig. 3, so that access can; be had to the priming pan when desired. Ordinarily, however, the priming pan will be hidden from view because the inner edge of the shelf 52 will coincide with the outer longitudinal edge of the member 35 and will overlap the brackets 36 and 37, there being vent openings 54 in the central portion of the shelf 52 to permit the products of combustion to pass upwardly through them.

I have found in actual practise that the arrangement of stove apparatus constructed in accordance with mv invention practically consumes all of the fuel so that there is no perceptible odor resulting therefrom. Therefore, under certain conditions I can eliminate the flue 11 or if it is present, I will not in all instances connect it to the chimney. Thus, the device is rendered portable and can be moved from place to place through the medium of handles 55 on the ends 1 and 2 of the stove casing.

It will also be apparent that the filler tube 14: can be eliminated and the tank filled through the tube 15 although the more convenient way will be to utilize the tube .14.

From the foregoing it will be apparent that a stove constructed in accordance with my invention may be rendered portable, that front of the casing at the lower edge of theopening and having an inwardly projecting fender-supporting v shelf forming a part thereof.

2. An oil stove comprising a casing having an opening across the front thereof, a burner across the casing at the lower edge of the opening and having fuel openings in its upper face, a guard hinged to the front of the casing at the lower edge of the opening and having an inwardly projecting fendersupporting shelf forming a part thereof, and

a hood projecting from the upper portion of the casing.

3. An oil stove comprising a casing having a front plate terminating short of the top thereof to provide an open front, the front plate having air vents therein, an oil burner in the casing, the upper portion of which is substantially in line with the top of the plate, a tank in the casing for supplying fluid '7 to the burner, and av valve for controlling the effective port area between the burner and the tank.

In testimony whereof I affix my signature.
