PROVISIONAL SPECIFICATION.
Improvements in or connected with Kitchen Ranges.
I, SAMUEL WILSON, of Riversley, Rothsay Road, Bedford, in the County of
Bedford, Gentleman, do hereby declare the nature of this invention to be as
follows:-
―
My invention relates to kitchen ranges and has for its object to lessen the fire
space, to economizè fuel and to arrange for flues at or below the level of the ordinary
fire-grate and to prevent such Blues from becoming choked with ashes or cinders
and at the same time to utilize the heat more effectively for the purposes required
than heretofore.
In carrying out my invention I employ a fire-grate which is made considerably
higher than the usual grates, the height being adjusted according to the size of the
fire without any reference to the height of the flues and preferably extending to
the level of the bottom of the fire-door.
In order to allow the heat to pass into the flues which, when my improved grate
is employed, are below the level of the latter, I form on or arrange in conjunction
with that side of the grate adjacent to the flue a plate having flanges at its sides,
which plate and flanges form with the back or side of the fire space of the range
a passage down and through which the heat can pass to the flues. In order that
the flues may be readily cleaned without disturbing either the grate or the fire I
form in the plate having flanges an opening normally covered by a door which
when removed affords free access to the flues.
I also in some cases provide my, grate with a sliding plate having openings
corresponding with those in the grate, the said sliding plate, when moved in one or
the other direction, serving to limit the quantity of air passing through the
grate.
When my improved grate is applied to a range having flues extending under
the hot plate I advantageously arrange in conjunction with the grate a pipe or
pipes which is or are heated by the fire and through which fresh air can pass from
beneath the grate and mix with the products of combustion as they pass into the
flue thus rendering the combustion more perfect than would otherwise be the case.
An important advantage of my invention is that no cold air is admitted into the
Hlues as is frequently the case with ranges having grates of ordinary construction
and consequently less fuel is required as no heat is wasted.

COMPLETE SPECIFICATION.
Improvements in or connected with Kitchen Ranges.
I, SAMUEL WILSON, of Riversley, Rothsay Road, Bedford, in the County of
Bedford, Gentleman, 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 :-
My invention relates to closed kitchen ranges and has for its objects to
economize fuel, to arrange for flues at or below the level of the ordinary fire-grate
and to prevent such, flues from becoming choked with ashes or cinders and at the

page_text: same time to utilize the heat more effectively for the purposes required than
heretofore.
In the accompanying drawing,
Figure 1 is a perspective view of so much of a kitchen range as is necessary to
illustrate my invention; and,
Figure 2 is a section on the line 2-2, Figure 1:
Figure 3 is a section on the line 3-3, Figure 2:
Figures 4 and 5 are respectively a perspective view and a sectional view
illustrating a modification of my invention.
According to my invention I arrange the fire-grate a considerably higher than
has heretofore been the case, for instance so that the depth of the fire shall at no
time exceed, say, six and a half inches, as I have found in practice that with a fire
of greater depth the combustion is not so perfect as with a shallow fire. The fire-
door b.is also so arranged that when closed against the front bars c, c it shall
completely exclude any air from entering through the said bars.
In order to allow the heat to pass into the flues which, when my improved grate
is employed, are frequently below the level of the latter as, for instance, is the
flue d of the boiler e, arrange in connection with that side of the grate adjacent
to such flue a plate having flanges 9, 9 at its sides, which plate and flanges form
a passage h down and through which the heat can pass as indicated by the arrows
Figures 2 and 5, the latter figure shewing the arrangement of the downward
passage when arranged for heating a side boiler.
In order that the flue d may be readily cleaned without disturbing either the
grate or the fire, I form in the plate f an opening normally closed by a door i
which, when removed, affords free access to the flues, as shewn most clearly; in
Figures 2 and 3; or, in the case of a side passage as. shewn in Figure 5, the
bottom of such passage may be closed by a door. As shewn in the drawing the
plate with the flanges 9, 9 is cast in one piece with the grate a but it will be
understood that such parts may be made separate if desired.
In order that the air which enters between the bars of the grate shall be heated
as much as possible before it comes into contact with the fuel I advantageously
make the grate with deep tapering bars as shewn in Figures 3 and 5 which afford
a large area against which the air can come into contact before passing into
the fire:
When my invention is applied to ranges having side flues extending over ovens
or boilers, I preferably provide the fire-place with cheeks; which are made hollow
or have openings through them through which air can pass from the under side of
the grate, such cheeks extending above the level of the grate a distance of, say
four inches; and in the upper part of this cheek I form openings into which I
insert pipes k, k forming bars between which the gases from the fire pass. These
pipes k, kare perforated on the side away from the fire' so that as the gases pass
between the said pipes fresh air will mingle therewith, whereby the combustion is
rendered more perfect than would otherwise be the case.
On the underside of my grate a sliding-plate is sometimes arranged having
openings corresponding to those of the grate so that when the said sliding-plate is
moved in one or the other direction it serves to increase or diminish the quantity
of air entering the fire.
One of the chief advantages of my invention is the exclusion of all cold air from
the flues thus ensuring that practically the whole heat of the fire is utilized whereby
the dampers can be kept more closed than was heretofore possible and consequently
effecting a great economy in the consumption of fuel.
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 a closed kitchen range or kitchener the combination with a grate arranged
at such a distance from the hot plate as to permit of only a shallow fire being used,

page_text: of a door for preventing the entrance of cold air through the front bars into the
fire and of a passage or passages such as extending downwards from the surface
of the grate to a flue or flues and provided with a door or doors for enabling the
said flue or flues to be cleaned without disturbing the fire, substantially as
described.
2. In a closed kitchen range or kitchener having a grate so arranged as to
permit of only a shallow fire being used and having a door for preventing the
admission of air through the front bars, the use of a hollow cheek for permitting
warm fresh air to mix with the products of combustion as the latter are passing
from the fire to the flue, substantially as, and for the purpose, described.
3. The improvements in kitchen ranges hereinbefore described and illustrated in
the accompanying drawing.
