of Middlesex, Surveyor, for the Invention of "IMPROVEMENTS IN PRO-
TECTING THE SUBMERGED PORTIONS OF IRON SHIPS, AND IN VENTILATING THE
"
PROVISIONAL SPECIFICATION left by the said Joseph Robinson at the
Office of the Commissioners of Patents, with his Petition, on the 16th
1.October 1862.
I, JOSEPH ROBINSON, of East India Road, in the County of Middlesex,
Surveyor, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN PROTECTING THE SUBMERGED PORTIONS OF IRON SHIPS, AND IN VENTILATING THE
CABINS AND CABIN DECKS IN IRON SHIPS," to be as follows:-
My Invention in protecting the submerged portions of iron ships consists in
covering the outer skin, from the keel to a little above the load-water lino;
with teak or other hard wood, and in fixing upon the wood thin copper plates.
I bend the frames at the sides, at those parts where the wood covering ceases,
so as to form a recess to receive the wood, and I continue the outer skin of
the upper part of the hull some distance down to cover the wood to enable me
to make a tight seam to prevent water entering between the wood and iron
skin. At that part of the hull, and to a little below the level to which the
wood is carried on both sides, there are three thicknesses, viz., the outer
plating or skin carried down from the top sides of the ship, the wood, and the
skin or plating which continues down to the keel.
My Invention in ventilating the cabins and cabin decks in iron. ships
consists in carrying an air pipe down through the upper waterway. to a little
above the waterway on the cabin deck, in carrying a pipe into or in forming

page_text: an aperture or apertures in the under plate of the upper waterway, and in
carrying pipes from the upper waterway, communicating with a funnel or
shaft. The air pipe is fitted with a cowl with a bell or other shaped mouth,
which can be turned to regulate or entirely shut off the supply of air through
the pipe.
Fresh air enters to the lower part of the cabins or cabin deck
while the vitiated air rising into the upper waterway is drawn off into the
funnel or shaft.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Robinson in the Great Seal Patent Office on
the 16th April 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPHI
ROBINSON, of East India Road, in the County of Middlesex, Surveyor, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of October, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Robinson, Her special licence that I, the said Joseph
Robinson, my executors, administrators, and assigns, or such others as I, the
said Joseph Robinson, 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 PROTECTING THE SUBMERGED PORTIONS OF IRON SHIPS, AND
IN VENTILATING THE CABINS AND CABIN DECKS IN IRON SHIPS," upon the
condition (amongst others) that I, the said Joseph Robinson, my executors
or administrators, by an instrument in writing under my, 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 Joseph Robinson, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, 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:-

page_text: My Invention in protecting the submerged portions of iron ships consists in
covering the outer skin A, Figure 1, from the keel to a little above the load-
water line, with teak or other hard wood B, and in fixing upon the wood thin
copper plates C, C. I bend the frames at the sides, at those parts where the
wood covering ceases, so as to form a recess D to receive the wood, and I
continue the outer skin E of the upper part of the hull some distance down to
cover the wood to enable me to make a tight seam to prevent water entering
between the wood and iron skin. At that part of the hull, and to a little
below the level to which the wood is carried on both sides, there are three
thicknesses, viz., the outer plating or skin E carried down from the top sides
of the ship, the wood B, and the skin or plating A which continues down to
the keel.
My Invention in ventilating the cabins and cabin decks in iron ships
consists in carrying an air pipe F, see Figures 1 and 2, down through the
upper waterway G to a little above the waterway H on the cabin deck, in
carrying a pipe I into or in forming an aperture or apertures in the under
plate of the upper waterway, and in carrying pipes K, K, from the upper
waterway, communicating with a funnel or shaft. The air pipe F is fitted
with a cowl L with a bell or other shaped mouth, which can be turned to
regulate or entirely shut off the supply of air through the pipe. Fresh air
enters to the lower part of the cabins or cabin deck through the pipe F, while
the vitiated air rising into the upper waterway is drawn off into the funnel or
shaft through the pipes K, K.
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,-
First, protecting the submerged portions of iron ships by means of wood
and copper applied substantially in manner herein-before described.
And, second, ventilating the cabins and cabin decks in iron ships by means
of pipes conveying fresh and carrying off vitiated air in manner described.
In witness whereof, I, the said Joseph Robinson, have hereunto set my
hand and seal, this Sixteenth day of April, One thousand eight hundred
and sixty-three.

JOSEPH ROBINSON. (L.s.)
