page_text: LETTERS PATENT to George Storey Moore, of Monkwearmouth, Sunder-
land, for the Invention of "AN IMPROVEMENT IN COMBINING STEAM ENGINES
AND BOILERS WHEN USED WITH SCREW OR STERN PROPELLORS OF SHIPS OR
VESSELS.'
"
Sealed the 23rd June 1857, and dated the 16th January 1857.
PROVISIONAL SPECIFICATION left by the said George Storey Moore at
the Office of the Commissioners of Patents, with his Petition, on the
16th January 1857.
I, GEORGE STOREY-MOORE, of Monkwearmouth, Sunderland, do hereby
declare the nature of the Invention for "AN IMPROVEMENT IN COMBINING STEAM
ENGINES AND BOILERS WHEN USED WITH SCREW OR STERN PROPELLORS OF SHIPS OR
VESSELS," to be as follows:-
This Invention has for its object an improvement in combining steam
engines and boilers when used with screw or stern propellors of ships or
vessels. Heretofore in applying steam engines to screw or stern propellors
it has been usual to place the engines and boilers below decks, which neces-
sarily occupies much of the most valuable space in ships or vessels.
Now my improvement consists in placing the engines below decks, and the
boilers on the decks, and in arranging suitable gearing to work the valves of

page_text: the engines from the deck. For this purpose it is preferred in each case to
employ two oscillating high-pressure steam cylinders inclined at right angles
to each other, and in a transverse direction to the keel of the ship or vessel,
the two piston rods being both connected to the crank of the propellor
shaft, and as near as may be to the propellor, in order to have as short a
propellor shaft as conveniently can be. The boilers and furnaces are placed
un deck, and by preference near the midships of the ship or vessel.
pipe descends from the boiler below decks and to the engines, and a return
steam pipe is conveyed from the engines to the boiler, furnace, or chimney.
By these means the weight will be better distributed, and valuable space
below decks obtained, whilst the whole working of the boiler and engine may
be from the deck,
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Storey Moore in the Great Seal Patent Office on
the 15th July 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
STOREY MOORE, of Monkwearmouth, Sunderland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth 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 George Storey Moore, Her special licence that I, the said George
Storey Moore, my executors, administrators, and assigns, or such others as
I, the said George Storey Moore, 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 thercin expressed, should and lawfully
night make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"AN IMPROVEMENT IN COMBINING STEAM ENGINES AND BOILERS WHEN USED WITH
SCREW OR STERN PROPELLORS OF SHIPS OR VESSELS," upon the condition (amongst
others) that I, the said George Storey Moore, 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.

page_text: NOW KNOW YE, that I, the said George Storey Moore, do hereby declare
the nature of the 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, that is to say:-
This Invention has for its object an improvement in combining steam
engines and boilers when used with screw or stern propellors of ships or
vessels. Heretofore in applying steam engines to screw or stern propellors it
has been usual to place the engines and boilers below decks, which necessarily
occupies much of the most valuable space in ships or vessels.
Now my improvement consists in placing the engines below decks and the
boilers on the decks, and in arranging suitable gearing to work the valves of
the engines from the deck. For this purpose it is preferred in each case to
employ two oscillating high-pressure steam cylinders inclined at right angles
to each other, and in a transverse direction to the keel of the ship or vessel,
the two piston rods being both connected to the crank of the propellor shaft,
and as near as may be to the propellor, in order to have as short a propellor
shaft as conveniently can be. The boilers and furnaces are placed on deck,
and by preference near the midships of the ship or vessel. A steam pipe
descends from the boiler below decks and to the engines, and a return steam
pipe is conveyed from the engines to the boiler, furnace, or chimney. By
these means the weight will be better distributed, and valuable space below
decks obtained, whilst the whole working of the boiler and engine may be
from the deck.
The Drawing shows a side view of a ship or vessel having the boiler and
engine applied thereto according to my Invention. The boiler is fixed on
deck at A, as shown by dotted lines. The engine is fixed near the stern of the
vessel, as shown. The construction of the boiler and of the engine may be
varied; they separately form no part of my Invention.
In witness whereof, I, the said George Storey Moore, have hereunto set
my hand and seal, this Eleventh day of July, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
ROBERT LAX.
GEORGE STOREY MOORE. (L.S.)
