Improvements in and relating to Kitchen Ranges and other Cooking
Ranges and Fire Places.
I, Charles WARD, of Helliwells Buildings, Ecclesfield, in the County of
York, Fitter, 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 improvements in the construction of kitchen ranges and
other cooking ranges and like fire places, having for its object the better con-
sumption of fuel and consequently the diminution of smoke.
The invention is clearly illustrated in the accompanying sheets of drawings, in
which similar letters of reference indicate similar parts in any of the several
figures.
Fig. 1, is an elevation of a kitchen range made according to my invention.
Fig. 2, is an elevation and section of fire door.
Fig. 3, sectional elevation of side cheeks, and other adjacent parts.
Fig. 4, plan of same with top plates removed.
In carrying out my invention in the construction of a kitchen range, such as shown
in the annexed drawings for example and which may be used either as an open or a
closed fire, it will be seen that the general outward appearance will not differ very
much from that of ordinary ranges, there being the centrally placed fire, with an
oven O, and a boiler B, on either side, but other forms or arrangements may be
used.
1 construct the fire preferably with the bars placed vertically and so arranged
that a burnt or damaged bar may be readily taken out and be replaced with a new
one, and I leave a space S, underneath them for clearing out the ashes from the
bottom bars, I also use a fall bar F. B, as shown.
A cover plate C, closes the top of the fire when required, and an ashes pan or
tidy T, provided with oblique plates to prevent a direct supply of air, covers the
opening under the fire.
The front bars and the opening S, may be closed by a door D, shown open.
When an open fire is required the coverplate C, is removed and the door D, is
opened as shown, a canopy or hood H, hitherto closed is drawn out and reveals an
opening.
This canopy or hood H, hangs upon side pivots and is supported when drawn
out and raised by two side plates S. P, having inclined top edges which turn on
pivots at the top and bottom, and when not in use are folded up in the entablature E,
forming the back.
The hood is raised by drawing out the first side plate, for which purpose a loop
or eye L, is provided.
When the canopy or hood and the side plates are drawn out, an opening A, is
exposed bebind a low front-plate C', passing downwards and opening into an air-
chamber F, behind the fire back plate G, which plate is provided with apertures J,
opening into the fire, and there are other openings communicating with the air
chambers K, at the back of the side plates M.
The side plates or cheeks M, and the walls N, of the chambers K, do not reach
the floor of the fire, but leave a space for flame and hot gases from the fuel to pass
under to the passage P, or to similar passages or flues of ovens, hot closets, hot
plates, boilers, and the like.
The cheeks M, of which a section is shown in Fig. 3, are made with apertures M',
protected with upwardly inclining gills M², which prevent the passage of fuel to

page_text: the back, and form an extended heating surface to aid in the combustion of any
unburnt gases and smoke passing over them from the fire to the flues.
The air ports which connect the back chamber F, with side chambers K, are
seen in Fig. 3, and are marked Q.
The door D, which is to close the front of the fire, see Figs. 1 & 2, is made
hollow, having several openings D', for the admission of air in front, and similar
outlets D2, for the air to pass to the different parts of the fire; room is left between
the top part of the door and the face of the fall bar, to allow air to pass down to
the opening R.
The bottom bars B B, I make separate instead of being in the form of a grate,
so that they can be readily renewed, and I make them of great proportionate depth
to heat the air as it passes between them to the fuel.
If a back boiler is used, I cut out a portion of the back plate G, so that the
boiler shall come in contact with the fire.
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-In kitchen ranges and other like cooking ranges and fire places, constructing
the side cheeks of the fire place with apertures for the passage of smoke and gases
into a chamber at the back thereof, the said cheeks having internal gills, substantially
as herein before described and shown for the purpose specified.
2 In kitchen ranges and other like fire places, the combination with perforated
cheeks as claimed in Claim 1, of a back plate having apertures communicating
with a chamber which is continued upwards, and opens under a hood, and which
also has ports opening into the side chambers substantially as herein before described
and shown.
3-In kitchen ranges and like fire places, a hollow door to shut against the front
bars, having inlet and outlet apertures arranged to cause the air to take an indirect
course for the purpose of heating same before it reaches the fuel, as hereinbefore
described and illustrated.
4-In kitchen ranges and other like fire places the combination and arrangement
of a closing hood H, a smoke entrance A, opening into chamber F, perforated back
plate G, perforated side plates M, hollow door with air inlets and outlets D2, for the
purpose specified, and substantially as described and shown.
