for the Invention of "IMPROVEMENTS IN THE CONSTRUTION OF COOKING
STOVES."
Sealed the 19th December 1879, and dated the 17th July 1879.
PROVISIONAL SPECIFICATION left by the said William Warren at the Office.
of the Commissioners of Patents on the 17th July 1879.

THE CONSTRUCTION OF COOKING STOVES."
"IMPROVEMENTS IN:
'
This Invention relates to the construction of cooking stoves in such a way that
the whole arrangement of fire place, boiler, ovens, hot plates, hot closets, and flues
arc all self-contained, so that no particular setting in brickwork is requisite, and the
stove may be used in the open air if required.
The fire is contained in a grate or fire basket, with a hot air space or chamber all
round, on one side of which is a boiler, and on the other side an oven.
From the top of this hot air chamber lead three flues, one at the back and one at
each side. These three flues all communicate with each other, and the back flue is
provided with an opening fitted with a stove pipe, and leading to the chimney or
to the open air.
The flues pass round three sides of an oven placed above the fire and fitted with
several shelves, and outside the side flues I have two other ovens or hot closets (one
above the boiler and one above the first mentioned oven), which like the lower oven
are only heated from one side.
Shelves and stands are provided for the reception of pans, kettles, or other vessels
when removed from the ovens or from the fire, and a draw plate is also provided
for closing the front of the fire when first lighted or when a draught is required.
In some cases I modify the construction of this stove as follows:-The back fluc.
is made the whole width of the stove, and the side flues are placed at the outside, a
long hot plate being fitted above the fire place and boiler, with holes to receive the
cooking vessels. A smaller cooking stove and hot plate with vessel for boiling large
joints is substituted for the oven at one side of the fire grate.
The top ovens as well as being heated by the side flues and back flue, as before,
have also another flue passing over the top, and the stove pipe is connected with '
this latter instead of to the back flue, as in the preceding arrangement.

-THE-CONSTRUCTION OF COOKING STOVES."
"IMPROVEMENTS IN
This Invention relates to the construction of cooking stoves in such a way that-
the whole arrangement of fire place, boiler and ovens, hot plates, hot closets, and
flues are all self-contained, so that no particular setting in brickwork is requisite,
and the stove may be used in any convenient part of the room or in the open air if
required.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect; and in order that the same may be clearly understood
I have annexed hereunto two Sheets of Drawings illustrative thereof, and have
marked the same with figures and letters of reference corresponding with those in
the following explanation thereof:-
Fig. 1 on Sheet 1 of the Drawings annexed is a front elevation, Fig. 2 a vertical
section through about the line A-B, and Fig. 3 a horizontal section through about
the line C-D of one modification of my improved cooking stove.
The fire is contained in a grate or fire basket a, a, with a hot air space or
chamber b, b, all round, on one side of which is a boiler c, c, and on the other a hot
closet c¹, c¹.
'
From the top of the hot air space b, b, lead three flues d, d¹, d", one d at the back
and one at each side. These three flues all communicate with each other, and the
back flue d is provided with an opening fitted with a stove pipe e, e, and leading to
the chimney or to the open air.
The flues d, d, d", pass round the back and two sides of the oven f, f, placed
above the fire and fitted with several shelves; and I may here remark that this
oven placed above the fire and having flues all round is an important feature of my
Invention. Outside the side flues d', d¹¹, I have two other ovens or hot closets g, g¹,
one above the boiler c, c, and one above the hot closet c', c¹, first mentioned, all of
which ovens or hot closets are only heated from one side and have no back flue, like
that of the oven f, f. h, h, is the ash pan.
Shelves and stands i, i, are provided for the reception of pans, kettles, or other
vessels when removed from the ovens or from the fire, and a draw plate is also
provided for closing the front of the fire when first lighted or when an increased
draught is required.
Fig-4-is a front elevation, Fig. 5. a vertical section through about the line E-F,
and Fig. 6 a horizontal section through about the line G-H.-
In this modification the back flue d, d, is made the whole width of the stove and
over the top of the ovens f. f, (of which there are two), and the side flues d¹ and d
are placed at the outside, a long hot plate k, k, being fitted above the fire place a, a,
boiler c, c, and hot closet c¹, c¹, and fitted with holes to receive the cooking
vessels.
A. damper l, l, is also provided, which when the ovens f, f, are not required can
be drawn out so as to close the oven flues and open a communication direct from the
fire place to the chimney flue e, e.
The fire basket a, a, is made with a movable back m, m, which can be drawn
forwards by means of a screw n, n, when only a small fire is required.
I sometimes make a small cooking stove for use in a corner of a room in the form
shown in elevation at Fig. 7, and horizontal section through the line I-K at Fig. 8.
In this case there is no boiler, and the door of the oven f, f, is at the side.
Two other modifications of the stove are shown on Sheet 2 of the Drawings, in
which Fig. 9 is a front elevation, Fig. 10 a vertical section (through the line L-M),

page_text: and Fig. 11 a horizontal section (through the line N-O) of a modification of the
arrangement shown at Figs. 4, 5, and 6, in which the depth from front to back is
considerably reduced by placing the hot plate k, k, and boiler e, e, below the ovens.
In the arrangement shown in elevation at Fig. 12 a smaller cooking stove a³, a³,
with a hot plate and a copper or vessel o, o, for boiling large joints (or for other
purposes) is added at one side, the hot water boiler e, e, being in this case above the
fire at the side of the oven f,f. This modification is so arranged that either of the
stoves may be used without the other when desired.
All these stoves are so constructed that they can be taken to pieces for removal
or stowage, and can be put together very quickly without either bolts, screws, or
rivets.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I would remark in conclusion that I do not wish to confine my Invention to
the precise modifications shown in the Drawings and above described, as various
other modifications might be made without departing from the distinctive features
of my Invention, and I desire it to be understood that I claim as my Invention,-
The construction of cooking stoves so that the fire place, boiler, ovens, hot plates,
hot closets, and flues are self-contained, substantially in the manner hereinbefore
described, such stoves being so constructed that they can be taken to pieces and put
together again without the use of bolts, screws, or rivets.
In witness whereof, I, the said William Warren, have hereunto set my hand
and seal, this Sixteenth day of January, in the year of our Lord. One
thousand eight hundred and eighty.
W. WARREN. (L.B.)
