the latter. The air space 46 between the shield 42 and the stove body A serves to edualizeand regulate the heating of the ;reservoir containing the wick and gasoline, thereby promoting-and controlling the vaporization of the gasoline and making the stove burn more steadily, especially when used in a drafty or windy location. Since vaporization of the fuel depends on the heat.

transmitted thereto from the burner, it is important that the reservoir be insulatedso that vaporization of all the fuel may take place evenly. A carrying handle 41 may be provided for the entire unit which should preferably-be secured to the outside wall of the body A by means or ears 'A preferred-embodiment of the invention con sists of a stove body A substantiall -six inches-in diameter and 4 inches highs The inner cyl' inder I3 should be approximatel 2 /2 inches in diameter and three-inches high and the base should be approximately 1 /2 inches high. The base perforations l1 should'b'e approximately inch in diameter and spaced /2 inch from the bottom edge ofthe base 'and'may be twelve in number. The inner opening of the grate B should'be 2% inches in dia'meter'and the central cylinder 39 of the cap C shouldbe approximately 2% inches in diameter'and inch high, leaving aflame opening 49 about% inch the two members B and C. a

The apertures 3| in the inner flange 24 of the grate'a're spaced approximately midway betweenthe top and bottom of the flange. In order to secure a properly balanced supply of air and fuel vapor for the burner there maybe providedtw'en ty-two inch apertures 3i, fifty-three apertures 36" in theplate 32 andfifty-three 1 6 apertures3'l in the flange 33.

In operation the" grate B'is lifted froin 'the body of the stove and three to four ounces of gasoline are evenly distributed overtheasbes-i tos or sand. The grate is replaced and the stove is lighted by applying a fiame to the annular opening 49 above the burner'formed' between the grate B and the burner cap C. Air enters thestove through the perforations I! in the base and flows upwardly through the small inner cylinder l3 of thebody. Inside the burner cap-C the air mixes with the vaporized fuel entering through the openings 3'! and this mixture es caping through the openingsfifi is ignited at the outside of 'the cap. Additional fuel vapor from the annular opening between the burner cap and the grate is entrained inthe current flowing up-' wardly through the openings 36, and additional air for completing the combustion of the fuel vapor enters the flame passage through the open-'- ings 3! inthe grate and through the perforated draw fuel vapor in through the openings31, Therate of fuel consumption is about three ounces of gasoline per hour. -Canned food, utensils or wide between tions being located in a plane broken, lost, or out of adjustment. At the same time it furnishes a regulated supply of heat with maximum fuel utilization and efiiciency in combustion because of the relation between the grate and the burner cap and the design of the air admitting apertures.

The invention accordingly consists in the features and arrangements exemplified in the structure heretofore described, the scope and application of which are indicated in the following claims.

We claimf 1. A pressureless gasoline stove comprising an annular-fuel reservoir having'spaced outer and inner walls and adapted to receive fuel absorbent material, said reservoir having its outer wall higher than its inner wall, a removable grate and flame restricting member mounted on said outer wall and extending inwardly toward said inner wall to cover the reservoir andform a restricted passage with said inner wall, and a removable burner cap supported'on said inner Wall in spaced relation to said grate and receiving air frombelow to the space within the inner wall, said cap'having perforations for the admission of fuel vapor and perforations for the'escape of mixed vapor and air, said last-named perforaabove said firstnamed perforations. I

2.- A pressureless gasoline stove comprising an annular fuel chamber having an inner wall form-' ing a central air-admitting passage and an outer wall spaced from said inner wall, said 'inner wall having at its top a perforated extension, and a removable grate supported on said outer wall and extending inwardly to cover said fuelchamber wall and said perforated extension, said grate comprising an upwardly'opening annular channel member and a series of grate bars supported across said annular channel on the outer and inner rims of said channel, whereby said annular channel and said grate bars may be'unitarily removed from or inserted into said stove. V

3. A pressureless gasoline stove comprising an' annular absorbent filled fuel reservoir, a central air admitting passage being provided'within said reservoir, means forming-a burner spaceat the end of said passage and communicating with said passage and with said reservoir, said fuel being vaporizable in the reservoir b the heat of cornbustion in' said space, said last-namedmeans having perforations 'for the admission of fuel vapor-and perforations for the escape of mixed vapor and air,.said last-named perforations being located in a plane above said first-named per-' forations, an' apertured base for said reservoir through which air is supplied to said central passage, and a wind screen having means friction-' all securing it to-said stove'body and forming an insulating chamber around said reservoir, said wind screen extending upwardly across the planeof said first-named perforations in said burner cap, and said wind screen securing means projecting below said wind screen to support it in spaced relation to the bottom edge of said aper tured base. I

4. A portable gasoline stovercomprising an annular open-topped fuel chamber having an inner cylindrical wall forming a central air passage and a higher outer Wall, a removable grate having a channel-shaped annulus telescoped within said fuel chamber and grate bars extended transversely across said annulus, said annulus having an external flange resting on the top of said outer wall, and a removable burner cap having a portion telescoped within said lower inner cylindrical wall and a flat-topped portion projecting above said wall, said last mentioned portion having series of perforations on its side and around its top and an upwardly projecting perforated cylinder secured to said top and extending within and spaced from said annulus to form a flame passage.

5. A portable gasoline stove comprising an annular fuel reservoir having a central air admitting passage, a burner cap mounted over said central passage, means providing an annular burner passage adjacent said cap, said cap having a portion enlarged to extend over the reservoir and having a perforated zone at the side to draw in fuel vapor from the reservoir and having perforations in a plane above said zone for the escape of mixed air and vapor, and means within said cap to direct the incoming air toward said last-named perforations.

6. A stove as defined in claim 5, wherein said first-named means comprise a cylindrical extension on said cap and an annular grate carried by said reservoir, said grate and said burner cap extension being perforated for the admission of air to the flame.

7. A portable gasoline stove comprising an annular fuel reservoir having a center air-admitting passage, a burner cap mounted over said center passage, means providing an annular burner passage adjacent said cap, said cap having a portion enlarged to extend over the reservoir and having a perforated zone at the side to draw in fuel vapor from the reservoir and having perforations in a plane above said zone for the escape of mixed air and vapor, and annular bafile means within the cap to direct the incoming air towards said last-named perforations.
