IMPROVEMENTS IN BOILERS FOR HEATING WATER FOR WARMING BUILDINGS
Year: 1874

page_text: LETTERS PATENT to John Hartley and Zaccheus Sugden, Welded
Boiler Makers, of Halifax, in the County of York, for the Inven-
tion of "IMPROVEMENTS IN BOILERS FOR HEATING WATER FOR WARMING
BUILDINGS."
Sealed the 4th September 1874, and dated the 10th March 1874.
PROVISIONAL SPECIFICATION left by the said John Hartley and
Zaccheus Sugden at the Office of the Commissioners of Patents,
with their Petition, on the 10th March 1874.
We, JOHN HARTLEY and ZAOCHEUS SUGDEN, Welded Boiler Makers,
of Halifax, in the County of York, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN BOILERS FOR HEATING WATER FOR
WARMING BUILDINGS," to be as follows, that is to say :-
Our Invention relates to constructing saddle boilers for heating.
purposes with horizontal fire-places combined with vertical feed places,
and having also side flues to increase the heating surface. For this.
purpose our boiler is of the saddle shape, made of welded or rivetted.

iron, or made of cast iron; the sides and top are made hollow, forming
water spaces; the bottom part is made in the shape of a saddle, and
forms the fire chamber, in which are fitted the horizontal fire-bars. In
the water space at the top is left an opening, which is fitted with a
movable cover. This opening is for the purpose of putting in the fucl
which falls on the horizontal fire-bars, giving an easy access for feeding,
and doing away with the system heretofore employed of feeding through
the front and fire-place, but we may use the ordinary plan of feeding
through the front, in that case the cover is kept on the top fuel opening.
Near the top of the side water spaces are made side flues, through which
the fire, heat, and gases pass, giving an additional heating surface. The
fire produced by the fuel on the fire-bars passes to the back of the boiler,
then through the side flues in the water spaces, and through flues formed
by the brickwork setting; in these flues are midfeathers fitted to the
boiler sides for the purpose of allowing the flames, heat, and gases
travelling through the boiler sides to act round or partly round the side
surface of the outside side plates before escaping through the chimney.
By these means we are enabled to produce saddle boilers having large
heating surfaces, and allowing an easy access for feeding, giving a steady
fire, burning for a longer period than hitherto.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Hartley and Zaccheus Sugden in the Great
Seal Patent Office on the 10th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
HARTLEY and ZACCHEUS SUGDEN, Welded Boiler Makers, of Halifax, 2
in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of March, in the year of.
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said John Hartley and Zaccheus Sugden, Her
special licence that we, the said John Hartley and Zaccheus Sugden, our
executors, administrators, and assigns, or such others as we, the said John
Hartley and Zaccheus Sugden, our executors, administrators, and assigns,

page_text: 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 BOILERS FOR HEATING WATER FOR WARMING
BUILDINGS," upon the condition (amongst others) that we, the said John
Hartley and Zaccheus Sugden, our executors or administrators, by an
instrument in writing under our, 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 Zaccheus Sugden, on behalf of
myself and the said John Hartley, do hereby declare the nature of our.
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 hereto annexed and to the figures.
and letters marked thereon, that is to say :—
The said Invention relates to constructing saddle boilers for heating
purposes, with horizontal fire-places combined with vertical feed places,
and having also side flues to increase the heating surface. For this
purpose our improved boiler is of the saddle shape, made of welded or
rivetted iron, or made of cast iron; the sides and top are made hollow,
forming water spaces; the bottom part is made in the shape of a saddle,
and forms the fire chamber, in which are fitted the horizontal fire-bars.
In the water space at the top is left an opening, which is fitted with a
moveable cover. This opening is for the purpose of putting in the fuel:
which falls on the horizontal fire-bars, giving an easy access for feeding,
and doing away with the system heretofore employed of feeding through
the front and fire-place, but we may use the ordinary plan of feeding.
through the front, in that case the cover is kept on the top fuel opening.
Near the top of the side water spaces are made side flues, through which
the fire, heat, and gases pass, giving an additional heating surface. The
fire produced by the fuel on the fire-bars passes to the back of the boiler,
then through the side flues in the water spaces and through flues formed
by the brickwork setting; in these flues are midfeathers fitted to the
boiler sides for the purpose of allowing the flame, heat, and gases.

page_text: thus increasing the circulation, the flame and heated gases acting round
and partly round the side surfaces of the outside plates before escaping
through the chimney R.
In Figures 4, 5, 6, and 7 the flame and heated gases pass through an
opening M made in the back waterway B into a flue N at the back of
of the boiler, then through return flues J, into flues K, in a similar
manner to that herein-before described; O, ash-pit; P, fire-brick lining;
S, flow pipe. By these means we produce saddle or other boilers having
large heating surfaces, and allowing an easy access for feeding, giving a
steady fire to burn for a lengthened period without attention.
Having thus described our improvements and the best means we are
acquainted with for carrying the same into effect, we would have it
understood that we do not confine ourselves to the precise details shewn
and described, as these may be varied without departing from the
peculiar character of the Invention, but what we do claim is, the
general arrangement, combination, and construction of saddle and other
boilers for heating water for warming buildings, giving large heating
surfaces, and having top feeders, side flucs, and midfeathers fitted to
them, substantially as herein-before described and represented in the
accompanying Drawing.
In witness whereof, I, the said Zaccheus Sugden, have hereto set
my hand and seal, this Ninth day of September, in the year of
our Lord One thousand eight hundred and seventy-four.
