IMPROVED MEANS OR APPARATUS FOR CONSUMING SMOKE IN THE FURNACES OF STEAM BOILERS
Year: 1866

page_text: LETTERS PATENT to Robert Newton, of Lower Providence Mill, near
Keighley, in the County of York, for the Invention of "IMPROVED MEANS
OR APPARATUS FOR CONSUMING SMOKE IN THE FURNACES OF STEAM BOILERS,
Sealed the 5th January 1867, and dated the 21st July 1866.
PROVISIONAL SPECIFICATION left by the said Robert Newton at the
Office of the Commissioners of Patents, with his Petition, on the 21st
July 1866.
I, ROBERT NEWTON, of Lower Providence Mill, near Keighley, in the County
of York, do hereby declare the nature of the said Invention for "IMPROVED
MEANS OR APPARATUS FOR CONSUMING SMOKE IN THE FURNACES OF STEAM BOILERS,
ALSO IN OTHER FURNACES WHERE APPLICABLE," to be as follows:-
The object of my Invention is to produce a thorough combustion of the
smoke in the furnaces of steam boilers and other furnaces. For this purpose
I place an arch of brickwork within the furnace immediately behind the fire-
door, and having perforated the arch with two or more holes I insert small
pipes within the same, causing them to extend a short distance into the
furnace. The outer ends of these pipes I connect by means of branch pipes
with an air tube, this latter being supplied with a current of air by an ordinary
fan placed in any convenient position; a valve is also placed between the
fan and the jets in any desired position to regulate the admission of the air.
The above-named apparatus may be used either by itself, for the purpose of

page_text: smoke consumption only or in conjunction with my "Improved Means or
Apparatus for Generating Steam in Steam Boilers," for which I obtained
Protection, March 24th, 1866, No. 878, with the double object of consuming
smoke and generating steam; in the latter case the same main or supply air
tube may be made available for both.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Newton in the Great Seal Patent Office on the 21st
January 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
NEWTON, of Lower Providence Mill, near Keighley, in the County of York,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of July, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Robert Newton, Her special licence that I, the said Robert Newton,
my executors, administrators, and assigns, or such others as I, the said
Robert 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 Islands, and Isle of Man, an Invention for "IMPROVED MEANS OR
APPARATUS FOR CONSUMING SMOKE IN THE FURNACES OF STEAM BOILERS, ALSO IN
OTHER FURNACES WHERE APPLICABLE," upon the condition (amongst others) that
I, the said Robert Newton, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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...
ان
NOW KNOW YE, that I, the said Robert Newton, 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
statement thereof, that is to say :-
The object of my Invention is to produce a thorough
smoke in the furnaces of steam boilers and other furnaces.
combustion of the
For this purpose

page_text: I place an arch of brickwork within the furnace immediately behind the fir-
door, and having perforated the arch with two or more holes I insert small
pipes within the same, causing them to extend a short distance into the
furnace. The outer ends of these pipes I connect by means of branch pipes
with an air tube, this latter being supplied with a current of air by an ordinary
fan placed in any convenient position; a valve is also placed between the
fan and the jets in any desired position to regulate the admission of the air.
The above-named apparatus may be used either by itself, for the purpose of
smoke consumption only, or in conjunction with my "Improved Steam Gene-
rator," for which I obtained Letters Patent bearing date March 24, 1866,
No. 878, with the double object of consuming smoke and generating steam,
in the latter case the same main or supply air tube may be made available
for both. I prefer, however, in some cases not to put tubes through the arch
above spoken of, but to put them behind the ordinary bridge; such tubes to
be made of clay (by preference), the largest diameters being, say, four inches,
and the remainder two inches, or such diameter as may be accommodated in
the flue. These tubes may be of the length of three feet, or two feet six
iuches, if desired.
The purpose of my Invention is either to use the apparatus named by itself
or in conjunction, as before stated, with my improved steam generator, for
which I obtained Letters Patent, bearing date March 24, 1866, and which
said Patent was sealed August 7, 1866.
In order, however, that my Invention may be the better understood, the
features of it may be seen by reference to the accompanying Sheet of Drawings.
It will be seen that the illustration shows the major portions of my previous
Patent before referred to, No. 878, A.D. 1866, that is to say:-
DESCRIPTION OF DRAWINGS.
Figure 1 shows a front elevation of the subject-matter of my previous Patent
in combination with my present one; Figure 2 shows a section in which my
improved apparatus, as described in my preferred arrangement, is illustrated;
Figure 3 shows the arrangement I prefer for the flues, the tubes being shewn
therein in section.
Letters A denote the pipes furnished with air from the pipe B by means of
the fan C. The air so supplied is passed through the small pipes d, as will
be seen on reference to Figure 2, into the furnace. The tubes before men-
tioned placed behind the bridge effect the result that I desire, viz., combustion
of smoke.
Ilaving now particularly described and declared the nature of my Invention,

page_text: I wish it to be understood that, without confining myself to the precise details
shewn in my Drawing, what I claim as and of my Invention is the improved
means or apparatus for the consumption of smoke in the furnaces of steam
boilers, or in other furnaces where applicable, by the use of the blast arrange-
ment shown conjointly with the tubular arrangement behind the bridge; or
separately, if desired, in the manner described and shown in this my Speci-
fication and my Drawings attached thereto, and therefore it will be seen that
my Invention consists mainly in the brick lining of the flue, the tubes behind
the bridge, and result, as named.
In witness whereof, I, the said Robert Newton, have hereunto set my
band and seal, this Nineteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-seven.
