IMPROVEMENTS IN STOVES OR FIRE-PLACES
Year: 1852

page_text: LETTERS PATENT to Henry McFarlane, of 8, Lawrence Lane, in
the City of London, for the Invention of "IMPROVEMENTS IN
STOVES OR FIRE-PLACES " A communication.
Sealed the 12th January 1853, and dated the 11th October 1852.
PROVISIONAL SPECIFICATION left by the said Henry McFarlane
at the Office of the Commissioners of Patents, with his Petition,
on the 11th October 1852.
I, HENRY MCFARLANE, of 8, Lawrence Lane, in the City of London,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN STOVES OR FIRE-PLACES" to be as follows:-:
This Invention consists of combining parts so as to obtain a more
advantageous stove or fire-place for heating rooms and other places,
and consists of combining an exterior and interior chamber, the fire
being in the interior chamber surrounded by sand or other absorbent
acting in like manner in the space between the interior and exterior
casings; at the lower part of such apparatus is a compartment for
receiving water; which can rise up thro' a perforated plate, and come
in contact with the lower part of the sand. Above the fire and sand
compartments is formed radiating apparatus, which may be varied, in
form; according to taste, but such apparatus consists of hollow-spaces com-

page_text: inunicating with the sand compartment, whereby when in use the heat
of the fire will cause the surrounding sand to be heated, which being
moistened with water from below, such water will be vapourized and
pass into the radiating apparatus above, and as the same condenses it
will fall to the lower part of the radiating apparatus and return to the 5
sand to be again vapourized; thus will the apparatus offer a large
extent of heating surface to the surrounding air.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry McFarlane in the Great Seal Patent
Office, on the 11th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
HENRY MCFARLANE, of No. 8, Lawrence Lane, in the City of London,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of October, in the year
of our Lord One thousand eight hundred and fifty-two, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry McFarlane, Her special licence
that I, the said Henry McFarlane, my executors, administrators, and
assigns, or such others as I, the said Henry McFarlane, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter 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 "IMPROVEMENTS IN
STOVES OR FIRE-PLACES," (upon the condition (amongst others) that I, the
said Henry McFarlane, by an instrument in writing under my hand
and seal, should particularly deseribe and ascertain the nature of the
said Invention, and in what manner the same was to be performed,
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 in compliance with the said proviso, I, the
said Henry McFarlane, do hereby declare that the nature of the

page_text: said Invention, and the manner in which the same is to be performed,
are fully described and ascertained in and by the following statement
thereof, reference being had to the Drawing hereunto annexed, and to
the figures and letters marked thereon, that is to say:
.
The Invention consists of combining parts so as to obtain a more
advantageous stove or fire-place for heating rooms and other places;
and consists of combining an exterior and interior chamber, the fire
being in the interior chamber surrounded by sand or other absorbent
acting in like manner in the space between the interior and exterior
casings; at the lower part of such apparatus is a compartment for
receiving water, which can rise up through a perforated plate, and
come in contact with the lower part of the sand. Above the fire and
sand compartments is formed radiating apparatus, which may be varied
in form according to taste, but such apparatus consists of hollow spaces
communicating with the sand compartment, whereby when in use the
beat of the fire will cause the surrounding sand to be heated, which
being moistened with water from below, such water will be vapourized
and pass into the radiating apparatus above, and as the same condenses
it will fall to the lower part of the radiating apparatus and return to
the sand to be again vapourized; thus will the apparatus offer a large
extent of heating surface to the surrounding air.
And in order that the Invention may be more fully understood, and
readily carried into effect, I will proceed to describe the Drawing here-
unto annexed, in the various Figures of which the same letters are
used to indicate the same parts.
DESCRIPTION OF THE DRAWING.
Figure 1, is a plan of a stove or fire-place constructed according to
the Invention; Figure 2, shows an elevation thereof; Figure 3, is a
vertical section; Figure 4, shows a horizontal section of the upper
part of the stove; and Figure 5, shows a horizontal section taken
below the fire. A, is the fire; B, are the fire bars or grate; C, is the
fire door; E, F, G, is the flue by which the products of combustion
passing from the fire first ascend, then descend, and then pass into a
chimney. The fire is surrounded by a chamber H, filled with sand or
other absorbent, below which there is a compartment K, containing

page_text: water, the partition d, which sustains the sand or other matter being
perforated, so that the water may rise just above the perforated bottom
or horizontal partition d, and a supply of water is from time to time
filled in at e. The upper part of the stove is composed of numerous
radial narrow chambers or compartments f, f, open to the centre,
closed at top and bottom, except at g, where the vapour rises from the
sand, and flows into the numerous radial compartments f, f. Any
water which may condense will return from the chambers f, f, back
into the sand by the opening at g, as will readily be understood on
examining the Drawing. By this arrangement a combination of parts,
when the fire is lighted, it will heat the surrounding sand, and conse-
quently evaporate the water, the vapour of which will ascend and flow
into the upper chambers or compartments f, of the stove, and thus
will a very extensive surface be heated with a moderate heat. I would
remark that although the upper compartments f, are generally used
simply as recipients of the vapour from the water, in some cases they
also may be filled with sand, or matters similarly absorbent of water;
and in place of these narrow compartments being arranged radially
they may be differently arranged, and their shape or form may be
varied as well as the form of the lower part of the stove.
Having thus described the nature of the Invention, I would have it
understood that what I claim is, the mode herein described of com-
bining parts into a stove or fire-place.
In witness whereof, I, the said Henry McFarlane, have here-
unto set my hand and seal, this Eighth day of February, in
the year of our Lord One thousand eight hundred and fifty-
three
