IMPROVEMENTS IN THE MEANS OF AND APPARATUS FOR CONSUMING SMOKE AND ECONOMIZING FUEL
Year: 1872

page_text: LETTERS PATENT to James Newton, of New Wortley, in the Borough
of Leeds, in the County of York, Flour Mill Manager, for the
Invention of "IMPROVEMENTS IN THE MEANS OF AND APPARATUS FOR
CONSUMING SMOKE AND ECONOMIZING FUEL."
Sealed the 10th June 1873, and dated the 14th December 1872.
PROVISIONAL SPECIFICATION left by the said James Newton at the
Office of the Commissioners of Patents, with his Petition, on the
14th December 1872.
I, JAMES NEWTON, of New Wortley, in the Borough of Leeds, in the
3 County of York, Flour Mill Manager, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE MEANS OF AND APPARATUS
FOR CONSUMING SMOKE AND ECONOMIZING FUEL," to be as follows:-
The object of this Invention is to effectually consume the gaseous
products of combustion arising from the burning fuel in the fire-place,

page_text: so that the heat evolved therefrom may be more completely utilized than
heretofore, and the fuel thereby economized. To this end the fire-place
(constructed partly of fire-brick and partly of iron) is placed at the front
end of the boiler, and partly projects into the fluc, which is constructed
of brickwork and of a serpentine form, so that the heat may be abstracted
from the gases as they travel forward. In order to keep the gasses in
motion along the flues they are drawn forward by means of an aspirating
fan actuated by a small engine fixed on the boiler, or by any other
convenient motive power. The gases as they are thus drawn forward
along the flues are supplied with a certain quantity of air, which will
assist in promoting their combustion, and that portion which is not
consumed will be forced by the fan or other motive power through the
incandescent fuel, and be thereby effectually consumed, so that none of
the combustible parts will be wasted. A chimney shaft to promote a
draft may be connected with the flues, so that in the event of the fan
getting out of order the action of the furnace and boiler need not be
stopped.
„SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Newton in the Great Seal Patent Office
on the 14th June 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
NEWTON, of New Wortley, in the Borough of Leeds, in the County of
York, Flour Mill Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Newton, Her special licence
that I, the said James Newton, my executors, administrators, and
assigns, or such others as I, the said James Newton, 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

page_text: Islands, and Isle of Man, an Invention for " IMPROVEMENTS IN THE MEANS
OF AND APPARATUS FOR CONSUMING SMOKE AND ECONOMIZING FUEL," upon the
condition (amongst others) that I, the said James Newton, 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 James Newton; 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 of " Improvements in the Means of and
Apparatus for Consuming Smoke and Economizing Fuel," is to effec-
tually consume the gaseous products of combustion arising from the
burning fuel in the fire-place, as that the heat evolved therefrom may
be more completely utilized than heretofore, and the fuel thereby
economized.
In the accompanying Drawing I have shewn the means whereby this
may be effected. Fig. 1 is a longitudinal vertical section, taken through
a boiler and furnace and part of the flues; Fig. 2 is an external end
elevation of the apparatus. The fire-place (constructed partly of fire-
brick and partly of iron) is placed at the front end of the boiler and
projects into the flue which runs through the boiler, and may be partly
constructed of brickwork. The flue is of a serpentine form, as shewn in
the sectional plan view, Fig. 3, of a modification of the boiler and fire-
place shewn at Fig. 1. By constructing the flues in this manner the
beat may be abstracted from the gases as they travel forward and
before they reach the exit flue or chimney or the blower hereafter
referred to.
The fire-place a is constructed with inclined fire-bars, and is fed from

page_text: fire-bars there is a chamber d to receive the clinkers as they are removed
by the stoker from the brass a. This chamber is provided with a door,
through which the clinkers may be withdrawn. Its bottom, which is
preferably made of metal, may be perforated to allow air to pass up
through the clinkers into the flue e to assist in consuming the combus-
tible gases thercin. A tubular chamber fis constructed of brickwork in
the flue, and air is admitted therefrom into the flues.
In order to keep the gases in motion along the flues e, e¹, in the
direction of the arrows in Fig. 3, they are drawn forward by means
of an aspirating fan g, Fig. 2, actuated by a small engine fixed on the
boiler, but not shewn in the Drawing, or by any other convenient motive
power. The gases as they are thus drawn forward along the flues are
supplied with a certain quantity of air, which will assist in promoting
their combustion, and those portions which are not consumed will be
forced by the fan g or other motive power into the box g¹, Figures 1 and
2, and from thence into the ash-pit, and through the incandescent fuel
on the fire-bars, so that they will be effectually consumed, and none of
the combustible parts will be wasted. A chimney shaft to promote a
draught may be connected with the flues, so that in the event of the
fan getting out of order the action of the furnace and boiler nced not be
stopped.
Fig. 4 is a longitudinal vertical section of another construction of
furnace, but on the same principle as Fig. 1; Fig. 3 is a sectional plan
view, shewing the serpontine arrangement of the flues; and Fig. 5 is an
external end elevation of Fig. 4.
The fan g may be made to suck in a certain quantity of air with the
combustible gases which pass along the flues, so that when the mixed
gases are forced into the fire-place they may be effectually consumed.
Having now described my Invention of " Improvements in the Means
of and Apparatus for Consuming Smoke and Economizing Fuel," and
having explained the manner of carrying the same into effect, I claim as
the Invention secured to me by Letters Patent as aforesaid, causing the
combustible gases evolved from the fuel to pass along a serpentine
arrangement of flues constructed partly of fire-brick, where their tem-
perature will be raised, and they will be consumed or partly consumed
by the admission of air thereto, and all unconsumed combustible gases

page_text: will be drawn forward by an exhausting apparatus, and forced through
the incandescent fuel, as and for the purpose herein set forth.
In witness whereof, I, the said James Newton, have hereunto set
my hand and seal, the Thirteenth day of June, in the year o
Our Lord One thousand eight hundred and seventy-three.
Signed and sealed by the said
James Newton in my presence,
BENJN. PULLAN,
Sol.,
JAMES NEWTON. (L.s.)
