page_text: LETTERS PATENT to John Moore Hyde, of Cumberland Iron Works, in
the City of Bristol, Iron Ship Builder, for the Invention of." IMPROVE-
MENTS IN IRON AND WOODEN SHIPS OR VESSELS, AND IN THE ADAPTATION OF
THE MACHINERY FOR PROPELLING THE SAME.
PROVISIONAL SPECIFICATION left by the said John Moore Hyde at
the Office of the Commissioners of Patents, with his Petition, on the
5th January 1857.
I, JOHN MOORE HYDE, of Cumberland Iron Works, in the City of Bristol,
Iron Ship Builder, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN IRON AND WOODEN SHIPS OR VESSELS, AND. IN THE ADAPTATION
OF THE MACHINERY FOR PROPELLING THE SAME," to be as follows:-
I construct the after part of iron or of wooden ships in a somewhat similar
manner to that adopted in my Invention patented the 29th Nov 1854,
No. 2513), but in this case adapt the ship for the reception of a propeller of
more than one blade; the great difference between the present and my former
Invention being that I increase the width of what is commonly called the
screw post," so as to admit of the propeller being enclosed, when needful, by
suitable shutters or sliding plates within the lines of the ship, arrangements
being made for the free deliverance of the water to the action of the screw.
Also I can adapt this arrangement to wooden ships so as not to materially
weaken or injure the structure of the same, which I purpose to effect by

page_text: cutting away the dead wood and then framing the said arrangement with the
shutters, &c. into the dead wood; or by adding to the after end of the
ordinary stern post and keel of wooden ships a frame of iron containing the
said arrangement with shutters, &c. Also I adapt the "run," or narrow part
of the after ends of an iron ship, in such manner as to use the same for a con-
denser; this I effect by partitioning off in the interior of the said parts so as
to strengthen the said ship, and at the same time admit of the condensing
chamber thus formed being provided with a man-hole to allow of its being
entered for the purposes of cleaning, repairs, &c., the efficiency of which con-
densing chamber may be increased by tho introduction of pipes to allow the
cold water from the outside the vessel to pass through the chamber.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Moore Hyde in the Great Seal Patent Office on
the 3rd July 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MOORE HYDE, of Gumberland Iron Works, in the City of Bristol, Iron Ship
Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the 5th day of January, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Moore Hyde, Her special licence that I, the said John
Moore Hyde, my executors, administrators, and assigns, or such others as I.,
the said John Moore Hyde, 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 "IM-
PROVEMENTS IN IRON AND WOODEN SHIPS OR VESSELS, AND IN THE ADAPTATION OF
THE MACHINERY FOR PROPELLING THE SAME," upon the condition (amongst
others) that I, the said John Moore Lyde, 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 Inven-
tion, 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.

page_text: NOW KNOW YE, that I, the said John Moore Hyde, 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:-
The nature of the said Invention, which has been already set forth in the
Provisional Specification accompanying the application for the said Letters
Patent, consists in this:-I construct the after part of iron or of wooden
ships in a somewhat similar manner to that adopted in my Invention patented
the 29th Nov 1854, (No. 2513), but in this case I adapt the ship for the
reception of a propeller with two blades, the great difference between the
present and my former Invention being that I increase the width of that part
of the ship adjacent to the "screw post" throughout its entire length, so as to
admit of the propeller being enclosed (when needful) by suitable shutters or
sliding plates within the lines of the ship, and for a distance of, say, two or
three fect immediately forward of the screw post, the said lines will be more
curved or "sudden" than the after body otherwise would be, as shewn in the
horizontal sectional Drawing, Fig. 2. Also I can adapt this arrangement to
wooden ships so as not to materially weaken or injure the structure of the
same, which I purpose to effect by cutting away the dead wood and then
framing the said arrangement with the shutters, &c. into the dead wood, or
by adding to the after end of the ordinary "stern post" and keel of wooden
ships a frame of iron containing the said arrangements with sliding shutters,
propeller, rudder post, and screw post in one wrought-iron frame, adapted to
be bolted on to the keel, the stern post and the dead wood thus forming an
external frame to the present frame of wooden ships, rendering it unnecessary
to cut out the dead wood. Also I adapt the run, or narrow part of the after
end of an iron ship, in such manner as to use the same for a condenser; this
I effect by partitioning off in the interior of the said part a portion of the run of
the ship sufficiently large for the purpose of condensing, which partitioning
strengthens the said ship where it is most required, and at the same time
admits of the condensing chamber thus formed being provided with a man-
hole to allow of its being entered for the purposes of cleaning and repairs,
the efficiency of which condensing chamber may be increased by the intro-
duction of pipes to allow the cold water outside the vessel to pass through the
chamber. The said pipes may be constructed of any convenient form to serve
the purpose of stays to strengthen the chamber, as well as to form additional
surface to the condenser, the condensed water from the steam being pumped
back into the boiler in the usual way.
Having thus described the nature of the said Invention, I now proceed to

page_text: describe in what manner the same is to be performed, by reference to the
Drawings accompanying this Specification, as follows:-
DESCRIPTION OF THE DRAWINGS.
Fig. 1, a longitudinal part section of a ship or vessel with my present im-
provements applied thereto; Fig. 2, plan view or horizontal part section of
the same; Fig. 3, transverse part section through the propeller. In these
Figures the following letters will refer to the parts hereafter mentioned. A,
rudder post; B, annular tube through which the shaft (D) passes, the annular
part being filled with cold water; C, condensing chamber, being the run
of the ship, strengthened as required with tubes or angle iron; D, screw shaft
or shaft from engine; d, air pump communicating pipe (Fig. 1); c, exhaust
pipe (Fig 1); F, screw post; I, propeller; P, sliding plates or shutters, raised
by means of a purchase on deck, and fitted into grooves in the rudder post (A)
and in the ship's sides s (Fig. 2); thus when let down the propeller I as well as
the screw post F is entirely enclosed within the run of the ship. R, rudder;
W, winch or purchase to raise the sliding plates; 0, 0, bulkheads of con-
densing chamber; m, man-hole in condenser; s, s, s, sides of ship (Fig. 2).
This description of the Drawing with what is stated in the outset of this
Specification, together with due inspection of the said Drawing, I deem suf-
ficient to enable the practical man to put my Invention into efficient operation,
and therefore I will now proceed, in order to ascertain the nature of this my
Invention, to state what I claim in respect thereof, viz. :-
I claim the constructing the after part of a ship or vessel as stated, so as to
.enable me to use a propeller of more than one blade, and enclose the same
(when needful) by means of shutters or sliding plates, as before explained.
Also I claim the adaptation of this system of enclosed shutters or sliding
plates to wooden ships, either let into the dead wood of the said ships, or
attached externally in a wrought-iron frame abaft the present stern post.
And also I claim adapting the run or after part of iron ships for the purpose
of condensing, by partitioning off a portion of the said run, as herein-before set
forth.
In witness whereof, I, the said John Moore Hyde, have hereunto set
my hand and seal, this First day of July, in the year of our Lord One
thousand eight hundred and fifty-seven.
JOHN MOORE HYDE. (L.S.)
