Year: 1855

page_text: LETTERS PATENT to James Heginbottom, of Ovenden, in the Parish of
Halifax, in the West Riding of the County. of York, Cotton Spinner,
for the Invention of "IMPROVEMENTS IN, FURNACES AND APPARATUS FOR
GENERATING STEAM, WHEREBY THE SMOKE WILL BE CONSUMED AND THE FUEL:
ECONOMIZED."
Sealed the 2nd May 1856, and dated the 3rd November 1855.
PROVISIONAL SPECIFICATION. left by the said James Heginbottom at
the Office of the Commissioners of Patents, with his Petition, 'on the
3rd November 1855.
I, JAMES HEGINBOTTOM, of Ovenden, in the Parish of Halifax, in' the West
Riding of the County of York, Cotton Spinner, do hereby declare the "nature"
of the said Invention for "IMPROVEMENTS IN FURNACES AND APPARATUS FOR
GENERATING STEAM, WHEREBY THE SMOKE WILL BE CONSUMED AND THE FUEL
ECONOMIZED," to be as follows:-
..
My Invention consists, firstly, in forming or making the sides and back part
or bridge of the ordinary boiler furnace or fire-place of a water space or
auxiliary boiler in connection with the main boiler, and so arranged that the
feed water on being supplied to the auxiliary boiler passes forward to the main
boiler, as also the steam which is generated therein.
Secondly, in having fires under the said auxiliary boiler, one on each side of

page_text: the main fire; the flames, &c. from the said auxiliary boiler fires meet the
flames from the main fire at the end of the grate bars.
Thirdly, in having a space betwixt the end of the grate bars and the back
part of the furnace, or bridge, or auxiliary boiler, for allowing the ashes, &c.
to be pushed forward from the grate bars into a box, or recess, or carriage, at
the back part of the ash-pits and under the back part of the auxiliary boiler,
where they remain for a time to be more thoroughly consumed, giving off heat
at the junction of the flames, whereby they greatly assist in generating
steam, consuming smoke, diminishing the quantity of ashes, and economizing
the fuel.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Heginbottom in the Great Seal Patent Office on the
3rd May 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HEGINBOTTOM, of Ovenden, in the Parish of Halifax, in the West Riding of
the County of York, Cotton Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Third day of November, in the year of our
Lord One thousand eight hundred and fifty-five, in the nineteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said James Heginbottom, Her special licence that I, the said James
Heginbottom, my executors, administrators, and assigns, or such others as I,
the said James Heginbottom, 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 "IM-
PROVEMENTS IN FURNACES AND APPARATUS FOR GENERATING STEAM, WHEREBY THE
SMOKE WILL BE CONSUMED AND THE FUEL ECONOMISED," upon the condition
(amongst others) that I, the said James Heginbottom, by an instrument in
writing under my hand and seal, 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
Royal Letters Patent.

page_text: NOW KNOW YE, that I, the said James Heginbottom, 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 (that is to say):
My Invention consists, firstly, in forming or making the sides and back
part or bridge of the ordinary boiler furnace or fire-place of a water space or
auxiliary boiler in connection with the main boiler, and so arranged that the
feed water on being supplied to the auxiliary boiler passes forward to the main
boiler, as also the steam which is generated therein.

Secondly, in having fires under the said auxiliary boiler, one on each side of
the main fire; the flames from the said auxiliary, boiler fires meet the flames
from the main fire at the end of the grate bars..
.
Thirdly, in having a space betwixt the end; of the grate bars and the back
part of the furnace, or bridge, or auxiliary boiler, for allowing the ashes, &c.:
to be pushed forward from the grate bars into a box, recess, or carriage, at the.
back part of the ash-pits and under the back part of the auxiliary boiler, where.
they remain for a time to be more thoroughly consumed, giving off heat at the
junction of the flames, whereby they greatly assist in generating steam, con-
suming smoke, diminishing the quantity of ashes, and economizing the fuel. :
And in order that my improvements may be clearly understood, I have
given the accompanying Sheet of Drawings, which represent furnaces and
apparatus in accordance with my Invention, the same letters referring to the
same parts in each Figure.
:
Fig. 1 is a front elevation of a steam boiler and furnace, with my auxiliary
boiler and furnaces attached, with brickwork, &c.; Fig. 2 is a vertical and;
longitudinal section of the same, taken through the line A, B, the back part
being broken away behind the bridge; Fig. 3 is also a similar section through
the line C, D; Fig. 4 is a cross section through the line E, F; and Fig. 5, a
horizontal section taken through the line G, H, (the whole length of boiler),
having parts broken away to shew the grate bars of the furnaces. a is an
ordinary boiler, with a horse-shoe flue; b, the auxiliary boiler, forming the two
sides and back part or bridge of the furnace to the ordinary boiler; c, the
grate bars of the ordinary or main furnace; and d, a space (for the ashes and
clinkers to fall through) betwixt the same and the bridge or auxiliary boiler;
e, the grate bars of the auxiliary furnaces; and f, spaces at the ends, as in the
main furnace; g, boxes or carriages to receive the ashes and clinkers when
pushed from the grates; and h are flues from the auxiliary furnaces, whereby
the flames encircle the side portions of the auxiliary boilers and meet the

page_text: flames of the main fire at the bridge thereof; i are pipes, connecting the
auxiliary with the main boiler; and j, the feed pipe.
It will be readily perceived that by these arrangements and construction of
apparatus I obtain a great additional heating surface, and by pushing the
clinkers and ashes off at the bäck, and allowing them to remain in receptacles
or carriages under the bridge or back part of the auxiliary boiler until cold (or
nearly so), ready for removal, they assist in generating steam, and also in con-
suming the smoke from the fires, which has to pass immediately over on its
way to the flue of the main boiler; also by firing or coaling the fires alter-
nately, the smoke from the fire newly coaled meeting with the hot flames from
the other two bright fires at the bridge becomes thereby consumed, whereby
fuel will be greatly economized.
Having thus fully described and ascertained the nature and particulars of
this my Invention, and the manner of carrying the same into practical effect, I
desire it to be distinctly understood that I do not claim the several parts of
this apparatus separately; but what I claim is,-
Firstly, the general arrangement and combination thereof.
And, secondly, the use and application of an auxiliary boiler and furnaces,
as herein described, and illustrated in the accompanying Sheet of Drawings,
or any modification thereof.
In witness whereof, I, the said James Heginbottom, have hereunto set my
hand and seal, this Second day of May, One thousand eight hundred
and fifty-six.
JAMES HEGINBOTTOM. (L.S.)
Signed, sealed, and delivered by the within-named
James Heginbottom, in the presence of
WM. TASKER, Halifax.
