Complete Specification Left, 13th May, 1889-Accepted, 29th June, 1839
PROVISIONAL SPECIFICATION.
A Novel Construction of Marine Boiler.
I, GEORGE KINGDON, of Dartmouth, County of Devon, Engineer do hereby declare
the nature of this invention to be as follows:-
This invention has for object, the construction of Marine Boilers to obtain rapid
generation of steam, a large steam reserve chamber, ready means of getting at tubes
for renewal, or repairs, the boiler being self contained with furnace complete.
For the purpose of my invention, I make the outer and the inner lower shell of
cylindrical shape, and forming the furnace portion. To the upper end of the inner
shell, I secure an inwardly curved or conical roofing and to the outer lower shell, I
secure an outwardly curved or conical shell, which may be in a piece with the lower
shell if desired, and with the upper end or edge slightly above the level of internal
coned roofing or crown of furnace.
On to this top edge, is rivetted the flange of a second inwardly curved or conical
shell and above this, a large steam space is formed by a dome fastened thereto.
Around the top edge of the outside lower cone, a skin is attached and to lower
part of the dome, forming a flue way and having on the top plate a couple of uptakes
or chimnies arranged diametrically opposite to each other.
The two inwardly curved or conical shells, carry flue or smoke tubes arranged
radially within them and all of them preferably at an angle of 45° so that they i.e.
the tubes, are surrounded by water, the level of which is within the upper flanged
portion of the upper inwardly curved or conical shell, where a large surface of water
is exposed to the steam dome for giving free escape of steam from the water.
The crown of the furnace and the dome are stayed by a tie rod and from the shape of
the lower outward spreading cone with that of the upper inward shaped cone, I obtain
not only room for fixing a large number of fire tubes but I preserve a large smoke
chamber, in which a workman can move freely for resetting a tube, or for repairs but.
by placing a shield on the outside and lagging the space between, I conserve the heat
of the products of combustion and gases for their utilization in transforming the .
water into steam.

COMPLETE SPECIFICATION.
A Novel Construction of Marine Boiler.
I, GEORGE KINGDON, of Dartmouth, County of Devon, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention has for object, the construction of Marine Boilers to obtain rapid
generation of steam, a large steam reserve chamber, ready means of getting at tubes
for renewal or repairs, the boiler being self contained with furnace complete.
For the purpose of my invention, which I show in the annexed drawings,
Figures 1, 2 and 3, I make the outer shell A and the inner lower shell B of
cylindrical shape. To the upper end of the inner shell B, I secure an inwardly
curved, or conical roofing C and to the outer lower shell A, I secure an outwardly
curved or conical shell D, which may be in a piece with the lower shell, if desired, as
shown. To this top edge is rivetted the flange of a second inwardly curved or conical
shell E and above this a large steam space is formed by a dome F fastened thereto.

page_text: Around the top edge of the outside lower cone D, and to the lower part of the
dome F a skin Ġ is attached to form a flue way H said skin having on it a couple of
uptakes or chimnies I arranged diametrically opposite to each other, or there may be
one chimney only as indicated at Figure 3.
The two inwardly curved or conical shells C, E, carry flue or smoke tubes J
arranged radially between, and all of them preferably at an angle of 45°, so that
they .e. the tubes J, are surrounded by water, the level of which is within the upper
flanged portion of the upper inwardly curved or conical shell E, where a large
surface of water is exposed to the steain dome for giving free escape of steam from
the water.
The crown C of the furnace and the dome F are stayed by a tie rod K and from
the shape of the lower outward spreading cone D with that of the upper inward
shaped cone E, I obtain, not only room for fixing a large number of fire tubes J but
I preserve a large smoke chamber, in which a workman can move freely for resetting
a tube or for repairs; but by placing a shield L on the outside and lagging the space
between, I conserve the heat of the products of combustion and gases for their
utilization in transforming the water into steam.
The lower part of the boiler forms the furnace M having the bars N and fire
door P.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
The novel construction of Marine Boiler having smoke tubes, J, arranged radially
between and affixed to a conical internal roofing C and an upper corresponding
conical shell E, as and for the purposes described and as shown on the annexed
drawings.
