7 Claims. (01. 126-38)
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 ?ow 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 to
gether in such manner that the burner assembly
can be placed inside of the housing during the
operation of the stove, and for convenient trans
porting of the unit both the burner assembly and
fuel tank can bev placed in the housing, thus
providing an exceedingly compact stove which
takes up very little room and can be conveniently
120 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 ad
vjustable to varying positions to control the
amount of fuel ?owing to the burners, thereby
controlling the ?ame producedrby the burners
30 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 manufac
ture, which comprises few working parts, is sim
ple in construction, and can be easily and quick
ly 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
40 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 op
erating position;

>
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
50 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 speci?cally to the drawings, and
55
in which like reference characters refer to like
parts throughout, a housing I0 is shown, pref
erably rectangular in shape‘and 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, par 5
ticularly as shown in Figure 5, is held in practi
cally vertical position, serving to protect the
burners from the action of the wind when using
the stove out of doors. An opening I2 is pro
vided 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 ex
tends across the top of the housing Ill and is
supported at its opposite side by the front side » 5
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 housing~ l0 when the stove is set up
in operative position as shown in Figure 1. Ex
tending longitudinally of the housing I0 and se
cured to the bottom thereof is a track l5 general
ly U-shaped in cross section and having a stop ,' 7
15 at the end thereof for purposes hereinafter de
scribed.
The burner assembly comprises a cooperating
track member H which is U-shaped in cross sec
tion and slightly less in width than the track 15
located in the housing 19, and is adapted to ?t
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 _ 35
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 40
a threaded nut 20 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 LiI D
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 05
1
2,105,340
2
and 3! being provided, this structure being sub
stantially 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,
proper degree to control the height of the ?ame
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 po
sition.
It will be understood, of course, that, a liquid
over which a cap 34 is secured and through which
additional air passes into the manifold 23 for
fuel such as gasoline or the like, is supplied to
the tank and by means of proper pump arrange
ment, as heretofore described, air under pressure
is placed in the tank l8, which forces the fuel
through the valve assembly, through the gen
erator 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
with a channel 38 in the valve stem. The link 31 7
is secured to a plate 39 which is pivotally mounted the whole structure placed inside of the housing
ii}. The legs are pushed inward and the lid and
on the side of the burner tube 25 by means of a
grid closed, making a compact package which
screw
46,
having
a
spring
4i
mounted
thereon
20'
can be easily transported and handled as desired.
and adapted to normally exert its pressure in
1O 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
15 lower end a link 3'! is secured having an opening
therein through which the valve stem 35 extends,
wardly against the‘ plate 39. The plate 39
as
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.
30
_ 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 move
ment of the rod 43 imparts a rocking action to
the plate 39 for purposes of opening and closing
‘as
the valve as heretofore described.
In the dis
assembled 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
40
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,
45 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 project
ing rod 44 which projects down over the mani
fold 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 up
ward, the assembly is removed from the housing
19, the burner assembly pushed into the housing
55 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
60 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 su?icient distance from
the ground to enable the fuel tank [8 to be placed
65 under the housing if}. The rod 43 is moved out
ward 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 condi
tion for operation, the fuel being supplied through
70 the valves as described in my Patent No. 1,914,393.
In case it is desired to use the burner 260, the
41
rod 43 is lifted upwardly, opening the valve 35,
thereby admitting the fuel mixture into the
burner-25a which is lighted. By proper adjust
ment of the rod 43 the valve 36 can be opened the
While I have described more or less precisely
the details of construction, I do not wish to be
