Year: 1852

page_text: LETTERS PATENT to James Dible, of Northam, in the County of
Hants, Shipwright, for the Invention of "IMPROVEMENTS IN VEN-
TILATING AND HEATING SHIPS, WHICH IMPROVEMENTS ARE ALSO APPLI-
CABLE TO EXTINGUISHING FIRE ON BOARD SHIP."
PROVISIONAL SPECIFICATION left by the said James Dible at
the Office of the Commissioners of Patents, with his Petition, on
the 2nd November 1852.
I, JAMES DIBLE, of Northam, in the County of Hants, Shipwright,
do hereby declare the nature of the said Invention for " IMPROVEMENTS
IN VENTILATING AND HEATING SHIPS, WHICH IMPROVEMENTS ARE ALSO APPLI-
CABLE TO EXTINGUISHING FIRE ON BOARD SHIP," to be as follows:-
My Invention consists in the application of pipes or chambers to any
part of either steam or sailing vessels for the supply of pure and fresh
air in combination with other pipes or chambers for carrying away the
impure and foul air. My Invention is also applicable for supplying warm
and heated air to the interior of vessels through such pipes or chambers,
and for extinguishing fires on board by admitting water through the
same pipes or chambers as are used for the supply of air..

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Dible in the Great Seal Patent Offico on
the 2nd May 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JAMES DIBLE, of Northam, in the County of Hants, Shipwright, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of November, in the year
of our Lord One thousand eight hundred and fifty-two, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Dible, Her special licence
that I, the said James Dible, my executors, administrators, and
assigns, or such others as I, the said James Dible, 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 "IMPROVEMENTS IN
VENTILATING AND HEATING SHIPS, WHICH IMPROVEMENTS ARE ALSO APPLI-
CABLE TO EXTINGUISHING FIRE ON BOARD SHIP," upon the condition
(amongst others) that I, the said James Dible, by an instrument in
writing under my hand and seal, should particularly describe and ascer-
tain 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 1, the said James Dible, 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 thereof, reference being had to the Drawings
hereunto annexed, that is to say:
My Invention consists in the application of pipes or chambers to any
part of either steam on sailing vessels for the supply of pure and fresh
air in combination with other pipes or chambers for carrying away the

page_text: mpure and foul air. My Invention is also applicable for supplying
warm and heated air to the interior of vessels through such pipes or
chambers, and for extinguishing fires on board by admitting water
through the same pipes or chambers as are used for the supply of air.
In the accompanying Drawing Figure 1, is a sectional elevation;
Figure 2, a plan; and Figure 3, a transverse section of a portion of a
vessel showing the application of my Invention for the purposes before
mentioned. I do not, however, limit myself to the particular arrange-
ments shewn of pipes and ventilators, as they must necessarily differ in
different vessels.
A, Figures 1, 2, 3, is a pipe terminating at top in a bell mouth for
conducting the pure air from above the deck to the interior of the
vessel. It may be placed in any convenient position. a, a, are handles
for the purpose of shifting its mouth to the wind; it communicates at
bottom with the branch pipes B, B, B, (which may be carried to any
part of the vessel), and which are represented in the Drawing open to
the cabin floor through the revolving ventilators or plates C, C, C, C,
shewn on an enlarged scale at Figure 4. By turning the lower of these
plates with the key K, the orifices in each plate are brought opposite to
each other, or the ribs of the under plate may be brought under the
orifices in the upper plate, and so close the draft.
D, D, D, Figure 1, are pipes which may be placed in any convenient
position for carrying away the impure and foul air; they are shown in
the Drawing as underneath the deck seats E, E, E, in which apertures
or perforations are made. The pipe A, is provided with a damper A',
for regulating the passage of air down the pipe, or for closing the
passage when required.
F, Figure 8, is a pipe provided with a cock, or valve, or any other
suitable contrivance, for the purpose of admitting water into the vessel
in case of fire. The pipe opens at bottom into the branch pipes B, B;
the top of the pipe is open to the water through the side of the vessel,
or is continued up level with the deck. Water may be distributed
through the branch pipes B, B, so as to flood every portion of the cabin
floors, magazine, store rooms, holds, or any other part of the vessel.
Should there be any difficulty in forming the communication between

page_text: the sea and the pipe F, water may be poured into it from the deck, as
also through the pipe A.
G, G, Figures 1, and 2, are branches from a pipe or pipes leading to
a stove boiler or other suitable apparatus for warming air, &c. When
heated air or steam are supplied, the damper or valve A', in the pipe A,
must be closed.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,-
Heating and ventilating ships and other vessels, and extinguishing
fire on board ships, by the means herein-before represented and 1
described.
In witness whereof, I, the said James Dible, have hereunto set my
hand and scal, this Twenty-eighth day of April, One thousand
eight hundred and fifty-three.
