7 Claims.

Myinvention relates to portable stoves of a variety adapted to burn liquid fuel, and has for its primary object the provision of a stove in which the burner assembly is enclosed within the housing during the operation of the stove, While the fuel tankis positioned outside of and under .neath .the housing, with means projecting out of said housing for controlling the flow of fuel to the burners in the stove assembly.

Another and further object of my invention is the provisionof a portable stove having a fuel burner assembly and fuel tank connected together in such manner that the burner assembly can be placed inside of the housing during the operation of the stove, and for convenient transporting of the unit both the burner assembly and fuel tank can be placed in the housing, thus providing an exceedingly compact stove which takes up very little room and can be conveniently packed or carried in an automobile or the like, for camping purposes.

Another and further object of my invention is the provision of a portable stove of the character described in which operating means for the burners are provided which extend through the housing to the outer sides thereof and are advjustable to varying positions to control the amount of fuel flowing to the burners, thereby controlling the flame producedrby the burners through the combustion of the fuel.

Another and further object of my invention is the provision of a camp stove of the portable variety which is exceedingly cheap to manufacture, which comprises few working parts, is simple in construction, and can be easily and quickly unpacked and placed in operable position for use with the burners, and also repacked in the housing for purposes of transportation. 7

These and other objects of my invention will be more fully and better understood by reference to the accompanying drawings, and in which Figure l is a side view, partially in elevation and partiallylin section, showing the stove in operating position; 7

Figure 2 is a top plan View of the stove shown in Figure 1;

Figure 3 is a transverse sectional View on line 3-3 of Figure 1;

Figure 4 is a plan sectional view showing the burner and tank assembly in packed relation in the housing; and

Figure 5 is an end elevational view of the stove as shown in Figure 4.

Referring now specifically to the drawings, and in which like reference characters refer to like parts throughout, a housing I is shown, preferably rectangular in shapeand having the usual bottom, sides and end portions, with an open top and a cover I I therefor which is hinged to the housing. In and which in the open position, particularly as shown in Figure 5, is held in practically vertical position, serving to protect the burners from the action of the wind when using the stove out of doors. An opening I2 is provided in the end wall of the housing l0 and a grid I3 is provided which is hinged at one of its sides to the rear wall of 'the housing II as shown particularly in Figure 2. This grid extends across the top of the housing Ill and is supported at its opposite side by the front side wall of the housing II]. A pair of U-shaped legs l4, i4 is provided which extend through slotted openings in the bottom of the housing l0 and have angularly disposed ends which are adapted to be received in openings formed in the front and rear walls of the housingl0 when the stove is set up in operative position as shown in Figure 1. Extending longitudinally of the housing I0 and secured to the bottom thereof is a track l generally U-shaped in cross section and having a stop 7 at the end thereof for purposes hereinafter described.

The burner assembly comprises a cooperating track member H which is U-shaped in cross section and slightly less in width than the track 15 located in the housing 19, and is adapted to fit into the track I5 when the stove is in assembled operative position. The track I? has a fuel tank l8 connected thereto by means of a member H], the ends of which extend around the sides of the fuel tank H3 at the end thereof, and are spot welded or otherwise secured to the fuel tank l8, this member also being spot welded or otherwise secured to the track member IT. The tank I8 has an opening in the end thereof within which a threaded nut is provided having a cylinder therein on the outer end of which a gland 2| is provided within which a piston 22 is mounted which provides means for pumping air into the fuel tank I8.

The fuel supply means comprises a manifold 23 having

burner tubes

24 and 25 projecting therefrom on the upper portions of which burners 26 and 26a are positioned in the usual manner.

The burner tube '24 has appropriate fastening I means, such as studs 2?, 21, by means of which the burner assembly proper is secured to the track IT. The manifold 23 has a generator tube 28 connected thereto with a valve body 29 on the outer end thereof, with suitable valves 30 and 3! being provided, this structure being substantially like that described and claimed in Patent No. 1,914,393 of June 20, 1933. A nipple 32 is provided which connects the valve body 29 with the pipe 33 connecting the valve with the fuel tank H8. The manifold 23 has openings in each side thereof between spaced trunnions, over which a cap 34 is secured and through which additional air passes into the manifold 23 for combustion purposes. a

The burner tube 25 extends upward, with a vertical passage therein within which a Valve stem 35 is positioned. On the upper end of the valve stem 35 a valve 36 is provided and on the lower end a link 3'! is secured having an opening therein through which the valve stem 35 extends,

with a channel 38 in the valve stem. The link 31 7 is secured to a plate 39 which is pivotally mounted on the side of the burner tube 25 by means of a screw 46, having a spring 4i mounted thereon and adapted to normally exert its pressure inwardly against the plate 39. The plate 39 has a pair of spaced

ears

42, 42 thereon through which a rod 43 is slidab-ly mounted and which is adapted to impart a. rocking movement to the plate 39 and through the link 31, thereby opening and ciosing the valve 36, admitting fuel to the burner 25a when it is desired to operate this burner.

In the operative position of the stove, the rod 43 extends through a slotted opening in the end of the housing ii) so that an up and down movement of the rod 43 imparts a rocking action to the plate 39 for purposes of opening and closing the valve as heretofore described. In the disassembled or packed position of the stove, this rod is moved inward, as shown particularly in Figure 4, so that the whole burner assembly can be packed inside of the housing I0.

In operation, the stove is normally in its packed position as shown in Figure 4, wherein the burner assembly and fuel tank are placed in side position on the bottom of the housing Hi, with the rod 43 pushed inward inside of the housing, the lid H being closed, in which condition the stove can be transported from place to place as desired. One of the grid members has a projecting rod 44 which projects down over the manifold 23 and serves to hold the stove assembly from movement when in its packed position in the housing Hi. When it is desired to assemble the stove for operation, the lid and grid are raised upward, the assembly is removed from the housing 19, the burner assembly pushed into the housing 10 through the opening l2, the track l1 being in engagement with the track 15 until a U-shaped stop member 45, mounted on the under side of the mixing tube 25, engages with the stop 16 and prevents further inward movement of the burner assembly and also prevents the burner assembly from tilting or rocking in the track l5. The legs M, in the meantime, have been withdrawn to support the housing if! a sufiicient distance from the ground to enable the fuel tank [8 to be placed under the housing if The rod 43 is moved outward so that the end thereof projects beyond the housing iii, the grid I3 is placed over the burners, in which position the stove is in condition for operation, the fuel being supplied through the valves as described in my Patent No. 1,914,393.

In case it is desired to use the burner 260, the rod 43 is lifted upwardly, opening the valve 35, thereby admitting the fuel mixture into the burner-25a which is lighted. By proper adjustment of the rod 43 the valve 36 can be opened the proper degree to control the height of the flame in the burner 2611, with the spring 4| exerting sufficient pressure against the side of the plate to hold this valve in its predetermined adjusted position.

It will be understood, of course, that a liquid fuel such as gasoline or the like, is supplied to the tank and by means of proper pump arrangement, as heretofore described, air under pressure is placed in the tank l8, which forces the fuel through the valve assembly, through the generator tube 28 into the manifold 23.

In disassembling the burner arrangement, it is only necessary to pull outward 0n the burner assembly, with the track I! sliding along the track l5 until the assembly is removed from the housing, when the rod 43 is pushed inward and the whole structure placed inside of the housing ii The legs are pushed inward and the lid and grid closed, making a compact package which can be easily transported and handled as desired.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as cirstances may suggest or render expedient without departing from the spirit or scope of my invention.

I claim:
