Serial No. 205903.

This invention relates to a new and improved stove construction, and more particularly to a construction of liquid fuel types of stoves of forms which are collapsible, in

order to render them readily portable. Stoves of this character, in general, comprise a housing, one or more burners, a fuel tank and connecting piping between the fuel tank and burners. It is customary to have such a connection between the fuel tank and burner assembly as to permit the tank to be placed within the housing for purposes of transport and to be placed outside of thehousing when in use. This is desirable since it permits a wall of the housing to be between the tank of inflammable fuel and the flame from the burners. In usual types of construction this result is obtained by disconnecting the tank from the burner assembly when placing the tank in the housing. This is undesirable, since it makes the tank a disconnected element which may become displaced or lost and also because it involves a loose connection in the fuel piping which may leak or become disconnected during the use of the stove.

It is an object of the present invention to provide a stove construction in which the tank is permanently connected to the burner assembly, and in which the tank may be moved 30 into and out of the housing.

' It is a further object to provide a construction of this character, in which the burner assembly is permanently connected to the housing.

It isalso an object to provide a construction in which the connection between the burner assembly and housing is adapted to permit displacement of the assembly relative to the housing such as to enable the tank to be lifted over a wall of the housing in moving it from one position to another.

Itis an additional object to provide a construction of this character, which is composed of but few and simple parts and adapted for rapid commercial production.

'2-2 of Figure 1; v

Other and further objects will appear as the description proceeds;

I have illustrated certain preferred embodiments of my invention in the accompanying drawings, in which 7 V Figure 1 is an elevation of one form of construction, certain portions being broken away;

Figure 2is a plan view taken on the line Figure 3 is a view similar to Figure 1, but showing the parts in the traveling position;

Flgure 4 is a section taken on the line 4.4 of Figure 2;

Figure 5 is a fragmentary view showing the fuel valve construction, and

Figure 6 is a view similar to Figure 1, but showing a modified formof construction.

Referring first to'the form of construction shown'ln Figures 1 to 5, the burner assembly 11 is carried within the housing 12. This houslng 12 is providedwitha hinged lid 13, with wind breaks 14 hingedly connected to the lid and with the pivoted supporting legs .15; The housing is also provided with the grate 16 which is .pivotally connected to the housing and which rests on'the flange members 17 and 18. I p

The fuel pipe 19 is connected at one end to the needle valve 20, which latter is secured to the 'fuel tank 21. The pipe 19 is alsosecured to the burners 22 and 23 by means of the clips 24: and 25 and its end 26 islocated so as to discharge into the lower portion of the burner assembly 11. 'The burner assembly is provided with the connecting pin 27, to the ends of which are secured the links 28. The links 28 are pivotally connected to the links 29, the opposite ends of which are secured to the'member 80, which latter is secured to the bottom of the housing 12.

The tank 21 has secured thereto the hooks 31, the upper ends of which are adapted to engage an edge of the housing whenthe stove is in operating position. As shown in detail in Figure 5, the needle valve is provided with the handle 32 by which the flow of fuel from the tank 21 to the pipe 19 may be controlled. The intake pipe 33 of the valve extends down close to the bottom of the tank 21. As shown in Figures 2 and 6, the tank 21 is provided with a valve fitting 34 by means of which'fuel may be placed in the tank. Also, this fitting permits air under pressure to be forced into the tank above the fuel, so as to force the fuel to pass up through the pipe 33 and pass the valve 20 and through the pipe 19 to theburners. 7 t The form of construction shown in Figure 6 differs from that previously described only in the means of connection between the'burner assembly 11 and housing 12 and in the construction and the connection of the fuel pipe.

In this form of construction the burner assembly 11 has connected thereto a pair of links 35, the opposite ends of which are connected to-"the member 36, the latter member being secured to the bottom of the housing. The pipe 37 connects the tank and burner assembly'and is held upon the'top ofburners 22 and 23 by clips 38 and 39. These clips 38 and 39 somewhat loosely engagethe pipe 37 so that it may be moved longitudinally relative to the burners.

The position of the tank 21 when traveling is indicated in broken lines at 21". The position of the inner end of gipetl'i when traveling is indicated at 37 by roken lines. The

burner assembly and link are in the same p0 sition when traveling and when the stove is in use. They are moved from this posit on only when moving the tank and connectlng piping fr m working to traveling position and vice versa. 1

In moving the parts of the form of construction shown in Figures 1 to 5 from the traveling position shown in Figure 3 to the working position shown in igure '1, it is merely necessary to lift the burner and tank assembly until thetank clears the upper edge of the side of the housing. to move it laterally until the hook members 3l-are located approximately abovethe edge of the housing and to lower it until the hooks engage the housing edge. The bottom of the burner assembly'will then rest against the member 30 inside of the housing, as clearly shown in Figure 1. To restore the parts totraveling position, the burner and tank assembly is. lifted, moved to the right and lovered to the position shown in Figure 3 These movements are limited and guided by the links 28 and 29 which permanently secure the parts together. It will be understood that during these movements ofthe burner and tank assembly it will be necessary to swing thelid or cover 13, the wind breaks 14 and the grate 1611p; out of the way. of the movement.

In moving the parts ofthe form of con struction shown in Figure 6 from the traveling position shown in broken lines to the operating position showing full lines, the left or tank end of the assembly is s zvung upwardly, so that the tank may clear the edge of the housing 12 andrthe tank is moved to the left away from the burner assembly until it may be lowered to bring the hooks 31 into engagement with the upper edge of the housing wall. This lateral movement of the tank is permitted by the sliding connection between the pipe 37 and the clips 38 and 39. In restoring the parts to traveling position, the tank end is swung up .until the tank may be moved to the right and then lowered into the housing. During this movement, the pipe '37 slides to the right relative to the .clips 38 and 39 and the burners 22 and 23.

It will be understood that in the use of the stove the tank 21is filled with gasoline or similar fuel through the filling opening closed by cap 34;. Air under pressure is then forced into the tank above the fuel. To start up the stove the Valve 20is opened by means of handle 32, and the'air pressure forces the fuel past the valve and through the pipe 19. It drips into the heating pan 40, and, when a small amount has accumulated'thcrein, it is ignited and serves to heat part of the pipe 19 and the burner 23. The gas in the pipe is thus vaporized by heat and passes out of the pipe 19 into the burner assembly in the form of vapor and then up through the assembly to the burner 23 where it is ignited. During the use of the stove the heat from the burners vaporizes the fuel in the pipe passing over them and none of the fuel enters the pan 10. The burner- 22 is controlled by valve 41. t

'. The supply pipe 33 extends nearly to the bottom of the tank 21 and therefore prac:

tically all of the fuel in the tank can be forced out by the air above it. The fuel leads from the pipe 19 at a level below that of the normal fuel level in the tank and the siphon action assists the flow of the fuel. The fuel'enters the burner assembly from below and rises to the burners and its movement is assisted by the normal upward movement of the heated gases.

While I have illustrated certain preferred embodiments at my invention, it is to be understood that I contemplate such further changes and modifications as come within the spirit and scope of the accompanying claims. I claim: 1.
