GASOLINE CAMP STOVE.

Application inea March s, 1927." sez-iai no. 172,302.

Automobile tourists, hunters, fishermen and others who do a considerable amount ot outdoor camping, iind it moreconvenient to employ for their cooking Va stove that burns hydrocarbon luel, such as gasoline, than to depend' on the wood camp tires. The great prevalence of automobile tourists has resulted in wood families along the highways, which makes it imperative that some other means ot producing heat than the old and well known wood lire must be provided.

It is the object of this invention to produce a camp stove of the type referred to which shall be oi' simple and substantial construction and in which the burner assembly and the 'uel tank shall be rigidly secured to the casing in suoli manner that they will be fully protected against injury during transporta tion and will be prevented from being accidentally. displaced with respect to each other.

lt is the further object ofthisinvention to produce a stove of this type in which the fuel tank shall be separated 'from the burner assembly by means o" a double partition wall whose interior is in tree communication with the air and whose upper portion is provided lwith a plurality oit opening-s so that when the burners are in operation, a` continuous stream ot air will circulate between the walls of the partition and thereby produce a heat insulating effect that prevents the tank 'from becoming unduly heated. i rllhe above and other objects which may become apparent as the description proceeds are obtained by means of a construction which briefly described, is as follows:

A rectangular metal casing having a bottom and a hinged top is provided for the pur- Y pose of enclosing` the burner assembly Vand the fuel tank. rThis casing is divided into two compartments by means of a hollov7 longitudinally extending partition. rllhis partition `is secured to t-he'bottom and the latter is provided with alarge number ot holes that communicate with the partition. A large number of holes is also provided near the top of the 0 partition so that air may iow upwardly between the walls of this partition whenever it becomes heated. The burner assembly is lo* cated in-one of thecompartments and the fuel tank is located in the other. The longitudi- ,5 nally extending partition serves as a heat insulating medium and protects the tank .from the heat generated by the burner while in operation. l

Having thus briefly described` the invention the same will now be described in detail, and reference for thispurpose will be. had to the accompanying' drawing in which the preferred embodiment has been'illustrated, and.

in which Fig. 1 is a plan view ol the stove with parts broken awayto better show theV construction; Fig. 2 is an elevation looking in the direc'-l tion of the arrow 2 in Figure 1; o Fig. 3 is a transverse section taken on line 3f-.3, Fig. 1 and shows the cover in closed posltion;

Fig. 4 is a section taken Online 4-4, Fig.y 1, and fshows the preferred construction of the hollow partition; and

Fig. 5 is a section taken on 5-5, Fig. 1, showing the manner ot connecting the generator tube to the burner.` 1 l Numeral 1 designates the. bottom of the casing. This casing has been shown as of rectangular shape and is provided with ends 2 and 3. These end members are connected at their respective` ends by sides 4 land 5. Side 4 is of the same height as the endmembers 'but side 5 is much lower.; The end members 2 and 3 have portions 6 and 7 which are bent at right angles andwhose lower edges are secured to the side 5 in the manner shown in Figure 2. A cover 8 is hingedly connected to the upper edge of sidel 4 and is provided with a. downwardly extending portion 9 which closes thel opening formed between the top of the `side 5 and the inclined edges of parts 6 and' 7. The casing is divided into two compartments A and B yby means of a `hollow partitionA which comprises two pan `allelmembers 10 and V11 of sheet metal which are integrallyconnected along their'upper edges and are provided along their lower edges with outwardly extending feet 12. This partition is secured to the bottom 1 by means of tongues 13 that are Jrormed integrally from the bottoni 1 and are bent over the feet 12 in the manner shown in Figure 4. A rabbet 14 is providedV along the upper edge of this partition wall sofas to form a support for the free edge or' the grate 15. The bottom memberl is provided with a large number of openings 16, which communicate with theinterior of the hollow partition, andthe partition member 10 is provided with a lplurality of openings 17 along its upper edge, so

that air may freely circulate in an upward direction through the interior of this Vhollow Y Loca-ted within the compartment 3A isV a' partition, The bottom of `cfoiiipartiiient Bis also provided with two rows ot openings 1,8,

which permit the tree circulation of air.

burner assembly, comprising two burners 19 and 2()` which are secured tofa-lternate ends of rllhis burner assembly is the manifold 21. supported on two Nl-shaped bracketssuch as shownrinFigure 3.

-k Having thus described the-inventioiiwhat s claimed as new isc 1. A campl stove.` comprising, .maconibiiiaf tion, acasing having avbottoin hinged cover, ahollow partition dividingfthemterior top forming' a of the casing into twoy compartments, a

burner assembly located within one of said compartments, a fuel tank located adjacent the partition within the other compartment, means for conducting fuel from the tank to the burner assembly and means for producing an upwardly flowing air current through the interior of and adjacent to said partition when the stove is in operation whereby the tank will be protected from the heat.

2. A camp stove comprising, in combination, a casing having a bottom and a hinged cover, a partition for dividing the casing into two compartments, said partition being formed from two parallel spaced members provided with a plurality of openings along the top, Vthe bottom being also provided with a plurality of openings communicating with the interior of said partition, whereby air may flow through the partition when the latter is heated, a burner assembly in one of said compartments, a fuel tank in the other compartment and means for conducting fuel from the tank to the burner assembly.

3. A camp stove comprising, in combination, a casing having side walls, end walls and a cover, a partition extending across the interior of the casing so as to divide it into two compartments of unequal size, a burner located in the larger compartment, a fueltank located in the smaller compartment, and a conduit extending from the fuel tank to the burner, the sides of the partition being in free communication with the air below the edges of the sides and ends of the casing whereby an unobstructed circulation of air may take place on both sides of the partition.

4. A camp stove comprising, in combination, a rectangular casing having spaced parallel side walls, spaced parallel end walls and a cover, a partition extending across the interior of the casing and dividing the interior thereof into two compartments of un equal size, said partition being formed from two spaced wall members, the space between the wall members being in communication with the atmosphere at the bottom and at the top of the partition whereby air may flow through the interior of the partition when the latter is heated, a burner in the larger com partment, a fuel tank in the smaller comparu ment adjacent the hollow partition and means for conducting fuel from the tank to the burner.

In testimony whereof we affix our signatures.
