IMPROVEMENTS IN THE CONSTRUCTION OF COOKING STOVES AND RANGES
Year: 1865

page_text: LETTERS PATENT to William Barton, of Boston, in the County of Lincoln,
Ironmonger, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF
COOKING STOVES AND RANGES."
Sealed the 20th October 1865, and dated the 26th July 1865.
PROVISIONAL SPECIFICATION left by the said William Barton at the
Office of the Commissioners of Patents, with his Petition, on the
26th July 1865.
I, WILLIAM BARTON, of Boston, in the County of Lincoln, Ironmonger, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF COOKING STOVES AND RANGES," to be as follows:-
The object of this Invention is to increase the heating surface in the boilers
and ovens of cooking stoves and ranges by so arranging the flues that the
flame and heated gases will pass down through them as well as playing over,
under, or around them, as is now commonly the case. The boiler will in
general be situate at one side of a closed fire-box and the oven at the opposite
side; these I make of any usual or approved external form, and I fit in
them a broad vertical tube, or it may be a set of tubes, forming thereby a flue
or flues through the boiler and oven of sufficient capacity to carry off tho
flame and gases of combustion from the closed fire-box. To permit of this I
connect the flues with the upper part of the fire-box, and conduct down them
the flame and heated gases, which after playing under and around the boiler

page_text: and oven will find an exit by flues at the back thereof to a common chimney.
For regulating the heat in these vertical flues I may use fly dampers operated
by lever rods, or equivalent mechanism.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Barton in the Great Seal Patent Office on the 26th
January 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BARTON, of Boston, in the County of Lincoln, Ironmonger, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of July, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Barton, Her special licence that I, the said William
Barton, my executors, administrators, and assigns, or such others as I, the
said William Barton, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE
MENTS IN THE CONSTRUCTION OF COOKING STOVES AND RANGES," upon the con-
dition (amongst others) that I, the said William Barton, my executors
or administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Barton, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement,
reference being had to the Drawing hereunto annexed, and to the letters and
figures marked thereon (that is to say):-
The object of this Invention is to increase the heating surface in the boilers
and ovens of cooking stoves and ranges by so arranging the flues that the
flame and heated gases will pass down through them, and will also play over,
under, or around them, as is now commonly the case. The fire-box is con-

page_text: structed of an angular shape, so that a small body of fuel, shallow in depth
from back to front, may be made to present a large. heating surface, which is
capable of being increased or diminished by raising or lowering the grate bars.
The front fire-bars are round in form, and moveable, as they are capable of
being raised by means of a rack bar placed below the ash grating, so as to
increase or diminish the depth of the.fire.
:.
In the accompanying Drawing, Fig. 1 is a sectional front elevation of my
improved cooking stove, the section being taken in the line 1, 2, of Fig. 2,
which is a plan view of the stove with the top plate removed.
The boiler a, which is provided with a man-hole, will in general be situated
at one side of a closed fire-box b, which is made of a form approximating to a
triangle, the widest part being in front. The oven c is placed at the opposite
side of the fire-place. These parts are made of any usual or approved
external form, and in and through the boiler a is fitted a broad, vertical
tube al, or a set of tubes, may, if preferred, be employed, in either case
forming a descending flue or flues through the boiler. The same arrange-
ment may be adapted to the oven, but the flues must be of sufficient capacity
to carry off the flame and gases of combustion from the fire-box 6. By this
arrangement all the heat when at its greatest intensity will be conducted into
the interior of the boiler and oven instead of being allowed to play merely
upon the outer surface of the same, whereby half the heat is wasted. To
permit of this the flue a² is connected with the upper part of the fire-box, as
shown at a³, and the flame and heated gases are thereby conducted into and
down through the descending flue space a¹ in the boiler, and after playing
under and around the boiler and oven they will find an exit by the flues a³ at
the back and sides thereof to a common chimney a'. For regulating the heat
in these vertical flues fly dampers operated by lever rods or equivalent mecha-
nism may be used, as is well known. The front bars of the fire-place are, by
preference, made round, and are attached to vertical racks placed at each side
of the fire-box. The construction of this part of the stove will be best under-
stood by referring to the detached sectional view, Fig. 3, in which it will be
seen that the grate or fire-bars d, d, which support the fuel, and also the ash-
pit grating e and curtain f are also attached to the vertical rack boxes 9, 9,
so that by raising these latter all the other parts will be raised as well, and
the capacity of the fire-box will be increased or diminished according as the
grate bars d, d,,are raised nearer to or lowered farther from the top plate h
of the stove. This raising and lowering of the vertical rack boxes, and the
other parts connected therewith, is effected by means of link-shaped holders on
the ends of the cross spindle or bar i, on one end of which is mounted a

page_text: handle j, whereby it may be actuated, so as to cause the bars or sides of the
link to take into the teeth of the racks, It will be seen that this spindle or
.bar is placed below the level of the ash-pit fire-bars, which is important in
the construction of the stove. In Figure 1 the racks and fire-bars are shewn as
raised to their highest point, so as to form as small a fire as possible; in the
detached sectional view, Fig. 3, they are, however, shewn as if partly lowered,
as when a more capacious fire-box is required.
Having now described my Invention of "Improvements in the Construction
of Cooking Stoves and Ranges," and having explained the manner of carrying
the same into effect, I claim as my Invention the construction and arrange-
ment of parts herein shewn and described, whereby the flame and heat from
the combustion of tho fuel in the fire-box may be made to heat the several
parts of the apparatus more effectually than heretofore..
In witness whereof, I, the said William Barton, have hereunto set my
hand and seal, the Twenty-second day of January, in the year of our
Lord One thousand eight hundred and sixty-six.
