FIG. 14 is a top plan View thereof; and
FIG. 15 is a bottom plan view thereof.
Referring to the drawings the portable stove accord
ing to the invention comprises a base part 10, shown in
its separated relation in FIGS. 11 and 12, preferably
containing grate may be in the form of an iron casting,
the various components being so related that the alumi
formed of cast ahuninurn and consisting of a circular
num components are etlectually protected from direct
ash receiving well 11 provided at its upper edge with an
contact with the fuel. Another object is to provide a 20 annular ledge 12 and a vertical annular wall 13 surround
stove in which the fuel containing grate has minimum
ing the ledge. The wall 13 is provided along its front
points of contact with the external body of the stove
and rear portions with a series of air inlet openings 14
and is surrounded by an air space, to the end that there is
and at its respective end portions with a pair of slots 15

remains comparatively cool while the grate effectually
retains its heat.
A further object is to provide a fuel
container having a primer receptacle for receiving a
suitable priming ?uid for quickly initiating the ignition
of the charcoal, briquets or the like.
Another object is to provide improved damper means
whereby the supply of air to the fuel containing grate
may be effectually controlled and evenly disnibuted.
A further object is to provide a stove having improved
means for adjusting the height of the food supporting
grill, pan or the like. Another object is to provide a
stove in which one of the food containing components
constitutes in one position of adjustment a substantially
air-tight closure which in cooperation with the damper
means in the closed relation of the latter will elfect the
plurality of suit-ably positioned supporting legs 17 ex
tend downwardly from the ledge 12 below the lower
surface of the ash receiving well 11, and a pair of handle~
extensions 18—18 extend outwardly from the opposite
ends of the base part and ‘are respectively provided with
hand grips 19-19 for the convenient lifting and carry
ing of the stove.
Centrally of the ash receiving well 11 there is pro
vided a raised boss ‘20 having a center hole 21 for receiv
ing an assembly screw, and which opens to a pocket 22
at the lower side of the boss for receiving an assembly
nut upon the screw, as will hereinafter more fully appear.

Other objects and advantages will become apparent
from a consideration of the following detailed descrip
tion taken in connection with the accompanying draw
ings wherein a satisfactory embodiment of the invention
is shown. However, it will be understood that the in
vention is not limited to the details disclosed but includes
all such variations and modi?cations as fall Within the
spirit of the invention and the scope of the appended
claims.
In the drawings:
FIG. 1 is a front elevation of the portable cook stove
with a series of openings 25 which in one position of
' adjustment register with the openings 14 of the wall 13
of the base member to provide a series of air passages,
and in the other position of adjustment are disposed be
tween the openings 14 so that the wall 24 of the damper
closes the openings 14. In intermediate positions of ad
justment the degree of opening of the air passages may
be varied. At the upper edge of the wall 24 there is
provided an inwardly and downwardly inclined annular
?ange 2-6 which constitutes a ba?le to direct incoming air
from the air passages downwardly mid inwardly toward
