I GEORGE JOHNSON of No. 1 George Street Oldham in the County of Lancaster
Machinist do hereby declare the nature of my invention for "AN IMPROVED
PORTABLE STOVE FOR COOKING CHIP-POTATOES AND OTHER ARTICLES OF FOOD
be as follows:-
:-
" to
The improved portable stove is constructed with an open frame of cast iron with
panels of sheet iron or sheet steel, the side panels holding the front and back
frames together by means of bolts or screws.
The furnace or fire door in place of being hinged is made to move up and down
in vertical slides, two springs being attached thereto to hold the door in any
position.

)
The top plate is provided beneath with a hanging casing or frame to support the
body of the fire box which is formed of a cylindrical block of fire clay with 'an
opening at one side corresponding with the fire door. The grating at the bottom
of the fire box is supported on the frame. The fire box is thus entirely detached
from the outside casing or frame work, there being a cylindrical cavity between
the two which prevents the excessive heating of the latter.
The cooking vessel or pan is removable and fits in a corresponding opening in
the top plate being provided with a flange all round to support it. And I would
here remark that for baking purposes a portable oven made of sheet iron or steel
may be substituted for the cooking pan, and for some purposes a flat stone may be
employed.

Above the cooking vessel is fixed a cover or hood open at the front and closed at
the back and sides.
:
This top cover is made with a sliding door and contains a hot water box or
plate to keep the cooked potatoes or other articles hot: the hot water plate
being provided with a supply cistern above and connected by a pipe with a
heating cistern or boiler which partly surrounds the flue or chimney at or near its

In the back plate of the cover is a long narrow slit or opening in connection
with the flue behind, extending from a little higher than the top of the cooking
pan and the under side of the cover, which carries away all steam and disagreeable
smell from the cooking.
The top cover and the flue are all fastened together and bolted down to the top
plate.

The improved portable stove for cooking chip-potatoes and other articles of
food is constructed with an open frame a of cast iron, and panels a¹, a³, of sheet
iron or sheet steel, the side panel a holding the front and back frame a together
by means of bolts or screws, or instead of holding the front and back frame a
together as described, tie bars aª suitably fastened to the latter may be employed.

page_text: The furnace or fire-door b in place of being hinged, may be made to move
up or down in vertical slides, two springs being attached thereto to hold the door
in any position, or preferably to slide sideways on a bar c in which latter case no
springs for holding the door in position are required:
The top plate d is provided beneath with a hanging casing or frame e to support
the body of the fire-box, which is formed of a cylindrical block of fire-clay f,
surrounded by a casing f¹, with an opening at one side corresponding with the
sheet iron spout 61, fixed to the frame a in front of the fire door b.
The grating g at the bottom of the fire-box, is carried by the top plate d by
means of the hang bars g¹.
The fire-box is thus entirely detached from the outside casing or frame-work'e,
there being a cylindrical cavity h between the two, which prevents the excessive
heating of the casing or frame 6.
The cooking vessel or pan i is removable and fits in a corresponding opening in
the top plate d, being provided with a flange i¹ all round to support it.
I would here remark that for baking purposes, a portable oven made of steel,
iron, or sheet iron may be substituted for the cooking pan i and for some purposes
a flat stone may be employed.
Above the cooking vessel is fixed a cover or hood k open at the front and closed
at the back and sides.
This cover or hood is made with a sliding door k¹ and contains a hot water-box
or plate to keep the cooked potatoes or other articles hot, the hot water box or
plate being provided with a supply cistern / above and connected by a pipe 11
with a heating cistern, boiler or coil which may partly surround, or be fixed
inside the flue or chimney m at or near its connection with the fire-place.
The coil is also connected, by means of another pipe 3, to the hot water box or
plate, and the latter by means of blow off pipe, to the supply cistern l.
The circulation of the water taking place in the ordinary way of the hot water
apparatus.
The cover or hood k above the supply cistern is formed with a hole and lid n,
to facilitate the filling of the supply cistern 1, with water, and to indicate the level
of water in supply cistern 1; a float n¹ is employed therein..
The spindle n of the latter passes through the cover or hood k, and is protected
if found necessary by suitable means.
In the back plate of the cover is a long narrow slit or opening p in connection
with the flue m behind, extending from a little higher than the top of the cooking
pan i, and the underside of the cover or hood kc, which carries away all steam and
disagreable smell from cooking.
The top cover or hood k and the flue m are all fastened together and bolted
down to the top plate d.
The front of the cooking pan i is partially surrounded by means of a dripper q,
serving to receive the necessary usual cooking utensils & protect the top plate d
from grease.
The dripper q rests on the top-plate d and is formed with a bent lip q', to hook
onto the cooking pan i, and be prevented from slipping off the top plate d.
Having now particularly described and ascertained the nature of this inven-
tion & in what manner the same is to be performed I declare that what
I claim, is ;-
First. The general arrangement and combination of parts constituting my.
improvements for the purposes and substantially in the manner hereinbefore
described and shown.
Second. The top plate d carrying a hanging casing or frame e in combination
with the fire-box f, f¹, in such a manner as to form a cylindrical cavity between
the hanging casing or frame e and fire box f, f¹, substantially as and for the purpose
set forth.

page_text: Third. Keeping the cooked food or articles hot by means of a hot water box or
plate k, through which circulates water heated by the flue, or hot gases passing
from the fire-box f, through the flue or chimney m substantially as set forth.
Fourth. The manner of carrying or drawing into the flue or chimney m, the
steam & disagreeable smell from cooking, away, substantially as and for the
purpose specified.
Fifth. The dripper q, in combination with the top plate d, and cooking pan i,
substantially as and for the purpose specified.
