IMPROVEMENTS IN FURNACES, FIRE-PLACES, AND STOVES
Year: 1856

page_text: LETTERS PATENT to William Young, of Queen Street, Cheapside, in the
City of London, Lamp Manufacturer, for the Invention of "IMPROVEMENTS
IN FURNACES, FIRE-PLACES, AND STOVES,"
Sealed the 6th March 1857, and dated the 19th September 1856.
PROVISIONAL SPECIFICATION left by the said William Young at the
Office of the Commissioners of Patents, with his Petition, on the 19th
September 1856.
I, WILLIAM YOUNG, of Queen Street, Cheapside, in the City of London
Lamp Manufacturer, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN FURNACES, FIRE-PLACES, AND STOVE," to be as follows:-
This Invention consists in a method of arranging furnaces, fire-places, and
stoves to facilitate the supply of air to the fuel, so that the combustion may be
more complete. For this purpose a tube is used, which passes up through
the centre of the grate, and supplies air to the fuel through a series of
longitudinal slits or openings. The tube is closed at the centre of the fire by a
disc or plate, so that the air to supply the lower part of the fire is drawn from
below, and the air to supply the upper part of the fire is drawn from above,
and is to a great extent heated by the fire acting on the exterior of the tube.
Price R

page_text: Underneath the fire is a cylindrical box for containing fuel, and the fuel is raised
as it is required by a screw or incline which nearly fits the cylinder, and as
the fuel is raised to the grate fresh fuel is supplied to the lower part of the
box by a suitable shoot.
The Invention also consists in a method of improving the draft for
obtaining a more complete combustion in the stove, already patented by me
on the Twenty-third of March 1855, and in other stoves and fire-places.
For this purpose a passage is arranged, which conducts the flame and a part
of the hot air back into the passage, by which air is supplied to the fuel,
so as to cause it to pass a second time through or over the fire. And another
method of arranging furnaces, fire plates, or stoves, so as to consume the
smoke, consists in mounting the fire basket or grate on a vertical axis, and in
dividing it at the top into two, three, or more divisions. Over the fire basket
or grate a plate projects, which covers one or more of the divisions. When
the fire requires feeding, fuel is placed on the uncovered part of the fire, and
then by rotating the grate the fresh fuel is carried under the covering plate,
and the smoke is obliged to descend and pass under the divisions, and rise
up through the bright part of the fire, and is thus consumed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Young in the Great Seal Patent Office on the
19th March 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
YOUNG, of Queen Street, Cheapside, in the City of London, Lamp Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of September, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Young, Her special licence that I, the said William Young, my
executors, administrators, and assigns, or such others as I, the said William
Young, 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 FURNACES, FIRE-
PLACES AND STOVES," upon the condition (amongst others) that I, the said

page_text: William Young, 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 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 I, the said William Young, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment thereof, that is to say :-
This Invention consists in a method of arranging furnaces, fire-plates, and
stoves to facilitate the supply of air to the fuel, so that the combustion may be
more complete. For this purpose a tube is used, which passes up through
the centre of the grate, and supplies air to the fuel through a series of
longitudinal slits or openings. The tube is closed at the centre of the fire by
a disc or plate, so that the the air to supply the lower part of the fire is drawn
from below, and the air to supply the upper part of the fire is drawn from
above, and is to a great extent heated by the fire acting on the exterior of the
tube. Underneath the fire is a cylindrical box for containing fuel, and the
fuel is raised as it is required by a screw or incline which nearly fits the
cylinder, and as the fuel is raised to the grate fresh fuel is supplied to the
lower part of the box by a suitable shoot.
Another method of arranging furnaces, fire-places, or stoves so as to consume
the smoke, consists in mounting the fire basket or grate on a vertical axis,
and in dividing it at the top into two, three, or more divisions. Over the fire
basket or grate a plate projects, which covers one or more of the divisions.
When the fire requires feeding, fuel is placed on the uncovered part of the fire,
and then by rotating the grate the fresh fuel is carried under the covering
plate, and the smoke is obliged to descend and to pass under the divisions
and rise up through the bright part of the fire, and is thus consumed.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawings hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section of a fire-place or stove arranged according to
my Invention, and in this Figure some of the parts cut off by the section are
indicated in red lines. a, a, is the fire basket; and b, 61, is a tube made in two

page_text: parts, and the parts are separated in the centre of the fire by the disc or
perforated cover c, which closes the upper end of the portion 6 of the tube;
d is a cylindrical box placed underneath the fire, and containing the screw or
incline e for raising the fuel supplied by the shoot f to the fire. For this
purpose motion is given to the screw by the lever g, see Figs. 3 and 4, which
when worked up and down causes the flanged wheel / to revolve; it so turns the
bevelled pinion h; this takes into the teeth of the bevilled wheel i on the axis
of the screw e. The portion b of the tube is continued downwards through the
screw e, of which it forms the axis, and this axis is capable of turning freely
in the upper part of the portion b, which is fixed and carried by the bar 62.
The portion b¹ of the tube passes up in or by the side of the chimney to the
upper part of the room, from which it draws the air to supply the upper part
of the fire. A similar arrangement of apparatus may be used for supplying
fuel to furnaces, and then the screw and cylindrical box is placed in front
of the bars next the fire door.
Figure 2 is a vertical section of another similar fire-place or stove, which
differs from that already described in that a conical or taper screw is used in
place of a parallel screw, and in consequence of the screw being so formed
I am able to place it in a vertical in place of an inclined position.
Figure 3 is a transversal section, and Figure 4 is a plan, of another form
of fire-place or stove in which the cylindrical box d and the screw e for
raising the fuel to the fire is placed in a horizontal instead of in a vertical
position. The shoot is placed at the back instead of at the side of the
fire, and the flanged wheel is fixed directly on the axis of the screw.
this fire-place or stove also the air pipe b, b', is dispensed with.
In
Figure 5 is a vertical, and Figure 6 is a horizontal, section of a fire-place or
stove arranged according to another part of my Invention. a is the fire basket,
mounted on centres b, b, which are carried by brackets c, c, at the top and
bottom, and these brackets are firmly fixed in the brickwork. a' is a plate
which divides the fire basket into two parts, but this plate does not pass to the
bottom of the fire basket; d is a plate projecting over the fire basket from
the back. When this fire is fed with fuel the basket a is turned half round,
so as to bring the fresh fuel under the covering plate, and then the smoke
formed by the fuel is obliged to pass down under the partition, and to rise
up through the bright fuel, and in this way it is consumed.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I do not confine
myself to the exact details described; but what I claim is,-

page_text: First, the arrangement of the air tube for supplying air to the centre of
the fire, as herein described.
Second, the use of a screw for raising the fuel to the fire in furnaces,
fire-places, or stoves, as herein described.
Third, the use of a revolving fire basket with a division and covering
plate, as herein described.
In witness whereof I, the said William Young, have hereunto set my
hand and seal, this Nineteenth day of March, in the year of our Lord
One thousand eight hundred and fifty-seven.
Witness,
FRED HARRIS.
