Improvements in Camp Cooking Outfits.
I, JOHN WILLIAM MACKENZIE of the Firm of Wheatley & Mackenzie,
Engineers and Patent Agents, of 40 Chancery Lane, in the County of London
do hereby declare the nature of this invention to be as follows:-
This invention relates to portable cooking kits for military use and general
camping purposes, designed to supply a boiler and oven and a metallic fire-jack for
supporting said boiler or oven and other cooking utensils above the fire, and which
fire-jack is adapted to form an enclosing and protecting crate within which the
boiler and oven and various utensils may be packed for transportation.
In carrying out the invention a pan-section is provided which is or may be of
about the full height of the kit when packed, except for the enclosing frame or
casing, or fire-jack, and this section is fitted to sit or nest into a second section of
any suitable height, which latter section is adapted to be inverted and shut into
or upon the first section to form a closed oven. Either of these pan-sections may
serve as a boiler or kettle when in use in camp, and when packed for transportation
the inner section, or it may be the only section, forms a receptacle within which
may be packed various pots, dishes, and other utensils, as may be desired. A cover
serves to close such receptacle and protect its contents.
To provide an open stove or fire-jack for the support of the pans or oven when
in use, and for a surrounding crate or casing to enclose the pans and contents
during transportation, a skeleton metallic frame is employed which may be
conveniently formed with end bars that are placed at a distance apart corre-
sponding to the length of the pan and are united by lateral bars which extend
along the upper lateral edges of the pan, or pan-sections. Said end bars are
turned down to extend along the sides of the pan, or pan-sections, and form
supporting legs, and at the bottom of said pan or pans are turned inwardly
beneath the exposed pan-section to enclose and support the same. These bottom
inturned reaches may be carried from side to side continuously, so that each end
bar forms a single unbroken loop enclosing the end of the pan-section or sections,
and thereby increase the rigidity of the structure by preventing the upright
reaches or legs from springing. In some cases, however, said inturned ends or
reaches may be cut off so as to separately extend beneath the pans only such
distance as may be necessary to properly enclose the same and to afford feet of
sufficient bearing surface to prevent the jack from sinking into the ground under
the weight of the utensils and cooking materials placed upon it when in use. The
lateral bars which unite the end bars, or certain of them, are turned over or down,
at one end of the frame, a sufficient distance to form stops practically closing that
end of the frame against the passage of the pau-sections. The other end of the
frame is left open for the introduction and withdrawal of said section or sections,
and the length of the frame is made such that when said sections are inserted and
pushed home until they abut against the stops at the closed end their opposite end
will be practically flush with the end of the frame.
The top portions of the end bars and the lateral bars are stayed by metallic
cross-straps, thus forming a grated or latticed top to the fire-jack, while the

page_text: depending legs are tied together by one or more lateral straps which may be
supported at suitable intervals by hangers fornied as continuations of the cross-
straps of the top. Obviously these hangers may be continued downwardly and
turned beneath the bottom of the pan to form additional supports for the sections,
if so desired.
That end of the pan or pan-sections which abuts against the closed end or stops
of the fire-jack, when packed together, is provided with a handle, which may be
hinged, so that the whole kit may be carried by said handle, the frame or fire-jack
then enclosing and holding the pans together and being retained thereon by the
stops, which come uppermost in this position owing to the location of the handle
with relation thereto. The opposite end of the pan, or pan-sections, is provided
with a staple and the corresponding open end of the fire-jack with a hinged hasp
which, when open, leaves said end of the frame free for the introduction of the
pans but, when closed, shuts down over the staple and is retained by a padlock or
any suitable fastening device.

Improvements in Camp Cooking Outfits.
I JOHN WILLIAM MACKENZIE of the Firm of Wheatley & Mackenzie,
Engineers and Patent Agents, of 40 Chancery Lane, in the County of London
do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to portable cooking kits for military use and general
camping purposes, designed to supply a boiler and oven, and a metallic fire-jack
for supporting said boiler or oven, and other cooking utensils, above the fire, and
which fire-jack is adapted to form an enclosing and protecting crate within which
the boiler and oven, and various utensils, may be packed for transportation; and
it has for its object to provide an improved construction in devices of the character
referred to.
In the accompanying drawings:
Figure 1 is a perspective view of a cooking outfit constructed in accordance
with said invention, showing the same as packed and ready for transportation.
Figure 2 is a similar view of the opposite end thereof.
Figure 3 is a transverse sectional view of the device.
Figures 4, 5 and 6 are perspective details of the pan sections and cover, and
Figure 7 is a perspective view of the fire-jack detached and alone.
A designates a pan-section which is or may be of about the full height of the
kit when packed, except for the enclosing frame or casing, and A¹ is a second pan-
section of any suitable height, into which the first sits or rests, and which is
adapted to be inverted and shut into or upon the first section to form a closed
oven. Either of these pan-sectious may serve as a boiler or kettle when in use in
camp, and when conjoined for transportation the inner section, or it may be the
only section, forms a receptacle within which may be packed various pots, dishes,
and other utensils, as desired. A cover B serves to close such receptacle and
protect its contents.
To provide an open stove or fire-jack for the support of the pans or oven when
in use, and for a surrounding crate or casing to enclose the pans and contents
during transportation, a skeleton metallic frame, C, is employed which may be

page_text: In
conveniently formed with end bars C¹, that are placed at a distance apart corre
sponding to the length of the pan, and are united by lateral bars C which extend
along the upper lateral edges of the pan or pan-sections. Said end bars Care
turned down, as at c, to extend down the sides of the pan or pan-sections and form
supporting legs, and at the bottom of said pan or pans are turned inwardly, as at c¹,
beneath the exposed pan-section or sections, to enclose and support the same.
the construction shown in Figures 1, 3 and 7 said inwardly bent ends of opposite
depending legs e are carried from side to side and joined continuously to each
other, and thereby increase the rigidity of the structure by preventing the legs
from springing. In some cases, however, said inturned ends e may be cut off, as
shown in Figure 2, so as to separately extend beneath the pans only such distance
as may be necessary to properly enclose the same, and to afford feet of sufficient
bearing surface to prevent the jack from sinking into the ground under the weight
of the utensils and cooking materials placed upon it when in use.
The lateral bars C2, which unite the end bars, are turned over or down at one
end a sufficient distance to form stops 2 and to practically close that end of the
frame against the passage of the pan-sections. The other end of the frame is left
open for their introduction, and the length of the frame is such that when said
sections are inserted and pushed home until they abut against the stop or stops c
at one end, their opposite end will be practically flush with the end of the frame.
The top portions of the end bars C and the lateral bars C are stayed by cross-
straps c, thus forming a grated or latticed top to the fire-jack, while the depending
legs c are tied together by one or more lateral straps e, which may be supported
at suitable points by hangers e formed by continuations of the cross-straps c³ of
the top, or otherwise. Obviously, moreover, these hangers may be continued
downwardly and around beneath the bottom of the pans to form additional supports
if so desired.
That end of the pan or pan-sections which abuts against the closed end or stops
of the fire-jack, when packed together, is provided with a handle D, so that the
entire kit may be carried by said handle, the frame or fire-jack then enclosing and
holding the pans together and being retained thereon by the stops which come
uppermost in this position owing to the location of the handle with relation
thereto. The opposite end of the pan or pan-sections is provided with a staple a,
and the corresponding open end of the fire-jack is provided with a hinged hasp C³,
which, when open, leaves said end of the frame free for the introduction of the
pans but, when closed, shuts down over the staple and is retained by a padlock, or
any suitable fastening device which will render the outfit secure against inter-
meddling. With this construction it is evident that either one or both pan-
sections may be carried, that the loss of the outer pan-section does not detract
from the efficiency of the device as a portable package, and that even if the inner
pan section is lost while the outer is retained, the latter may form the bottom of a
package which is effectively tied together and retained by the enclosing frame or
fire-jack.
The invention is not limited to the exact form or proportions of the parts
herein described, nor to the precise construction of the fire-jack, but,
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination with one or more pan-sections, of an independent skeleton
metallic enclosing frame or fire-jack having a grated top, sides which depend to and
are turned beneath the bottom of the exposed pan-section to embrace and support
it, stops on said frame or jack at one end to bar the passage of the pan-section,
and a free opposite end.
2. The combination with one or more pan-sections, one of which has a handle
upon one end and a staple at the other, of an independent skeleton metallic
enclosing frame having a grated top, depending sides turned in at their lower ends

page_text: to embrace and support the exposed pan-section, stops on said frame or jack at
one end against which the handle end of the pan-section abuts, and a hasp at the
other open end arranged to take over the staple on the pan-section.
