Year: 1853

page_text: LETTERS PATENT to John Getty, of Liverpool, in the County of
Lancaster, Merchant, for the Invention of "CERTAIN
MENTS IN SHIP BUILDING."
OVE-
Sealed the 25th November 1853, and dated the 1st July 1853.
PROVISIONAL SPECIFICATION left by the said John Getty at the
Office of the Commissioners of Patents, with his Petition, on the
1st July 1853.
I, JOHN GETTY, of Liverpool, in the County of Lancaster, Merchant,
do hereby declare the nature of the said Invention for " CERTAIN IM-
PROVEMENTS IN SHIP BUILDING" to be as follows:-
Firstly, in the construction of keels of ships and other vessels used
for navigation, which is effected by making the keel of a series of
thicknesses of rolled plate iron, placed side by side of each other, and
bolted or fastened together; the several plates are made to break joints,
which gives the whole when bolted together stiffness.
Secondly, for leaving a space below the iron plate forming the lower
part of the ribs and the floor of the lower deck, so as to allow a free
passage to the pumps for any water that may get into the hold or bilge
of the vessel.
Thirdly, for constructing masts of vessels used for navigation with a
combination of timber and iron, by forming the centre of the mast

page_text: with plates of iron placed at right angles to each other, and filling the
spaces forming the quadrants with timber, and connecting the whole
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Getty in the Great Seal Patent Office,
on the 31st December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN GETTY, of Liverpool, in the County of Lancaster, Merchant, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of July, in the year
of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Ierself, er heirs and suc-
cessors, give and grant unto me, the said John Getty, Her special
licence that I, the said John Getty, my executors, administrators, and
assigns, or such others as I, the said John Getty, 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 "CERTAIN IMPROVEMENTS IN
SHIP BUILDING," upon the condition (amongst others) that I, the said
John Getty, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said In-
vention, 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 John Getty, 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, that is to say:
My improvements in ship building have reference to the construc-
tion of the lower-parts of iron vessels, and consist in so arranging and
shaping the frames or ribs and the garboard. strakes of the vessel as

page_text: will ensure an uninterrupted passage to the pumps, from stem to stern
of the vessel, for any water that may collect in its hold or bilge.
The annexed Drawing represents a cross section of part of the hull
of an iron vessel built in accordance with my improvements. a, a, are
the frames or ribs, which are bent or curved at their lower portions in
the manner shewn, in order that they may not touch the keel in any
part. b, b, are the garboard strakes which, for the purpose of strength-
ening this part of the vessel, are formed of two plates of iron on cach
side of the keel, bolted or rivetted together. The two inner plates
forming the strakes are carried up sufficiently high above the kecl c,
to catch or touch the frames or ribs at the points d, d, and together
with the keel form a watercourse or open channel e, running the
entire length of the vessel; at the same time the frames or ribs being
bent across or bridging over the keel offer no impediment to the free
passage any water that may be contained in the channel e. Or,
instead of the frames or ribs being curved or bent as above described,
they may be brought to a point at their lowermost portions, the
garboard stakes being made sufficiently deep to prevent the frames
from touching the keel, and thereby destroying the continuity of the
channel.
of
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that what I claim
is, the formation of an uninterrupted channel or watercourse from end
to end of iron vessels in the manner above described.
In witness whereof, I, the said John Getty, have hereunto set my
hand and seal, this Twenty-eighth day of December, in the
year of our Lord One thousand eight hundred and fifty-
three.
