Itchen Ferry, Southampton, in the County of Southampton, Gentleman,
for the Invention of "THE USE OR ADAPTATION OF WATER PIPES OR SYPHONS
IN COMBINATION WITH TURBINE WHEELS OR OTHER HYDRAULIC ENGINES FOR
THE PRODUCTION OF MOTIVE POWER POR PROPELLING SHIPS."
Sealed the 16th July 1867, and dated the 18th January 1867.
PROVISIONAL SPECIFICATION left by the said Richard Robert Loane
Rosoman at the Office of the Commissioners of Patents, with his
Petition, on the 18th January 1867.
I, RICHARD ROBERT LOANE ROSOMAN, of Higblands, Itchen Ferry, South-
ampton, in the County of Southampton, Gentleman, do hereby declare the
nature of the said Invention for "THE USE OR ADAPTATION OF WATER PIPES OR
SYPHONS IN COMBINATION WITH TURBINE WHEELS OR OTHER HYDRAULIC ENGINES
FOR THE PRODUCTION OF MOTIVE POWER FOR PROPELLING SHIPS," to be as
follows:
By means of a water pipe or syphon through the bottom or side of a ship
I convey water to a turbine wheel or other effective hydraulic engine fixed in

page_text: the hold of the ship below the water line, thus taking advantage of the
difference of level of the water at the ship's water line outside and the turbine
wheel or other bydraulic engines within. I thus produce by the fall of the
water upon the turbine wheel or other hydraulic engine motive power. The
power so produced I utilize to set in motion machinery of any kind for the
propulsion of the ship, especially machinery for the propulsion of the ship by
means of the reactionary force gained by forcibly ejecting the water out of it
either above or below the water line. I use steam or other auxillary power
to assist in the ejection of the water, or otherwise as may be required. I
would add that my said Invention is applicable not only for the propulsion of
ships, but also for the production of motive power in all cases in which the
combined use of syphons with turbine wheels or other bydraulic engines can
be made applicable.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Robert Loane Rosoman in the Great Seal Patent
Office on the 18th July 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ROBERT LOANE ROSOMAN, of Highlands, Itchen Ferry, Southampton, in the
County of Southampton, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of May, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Richard Robert Loane Rosoman, Her special licence that I, the said
Richard Robert Loane Rosoman, my executors, administrators, and assigns,
or such others as I, the said Richard Robert Loane Rosoman, 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 "THE USE OR ADAPTATION OF WATER PIPES OR SYPHONS IN
COMBINATION WITH TURBINE WHEELS OR OTHER HYDRAULIC ENGINES FOR THE PRO-
DUCTION OF MOTIVE POWER FOR PROPELLING SHIPS," upon the condition (amongst
others) that I, the said Richard Robert Loane Rosoman, my executors or
administrators, by an instrument in writing under my, or their, or one of

page_text: 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 Richard Robert Loane Rosoman, 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:-
My Invention relates to ships and other vessels propelled by hydraulic power,
and consists in the use and adaptation of syphons or water pipes in combination
with turbines, water wheels, or other hydraulic motors for producing or
augmenting the propelling power.
The bydraulic motor for ejecting the water may be of any suitable
construction, but I propose to place such motor as much below the load
water line of the ship or vessel as circumstances will allow, in order to
obtain as great a column of water above the motor as possible, and in order
to increase this column I introduce a syphon-shaped induction pipe, up one
limb of which syphon the water passes from the outside of the ship and down
the other limb of the said syphon to a turbine wheel or other hydraulic motor
through which it passes, and is thereby forcibly ejected at the stern, sides, or
stem of the ship by suitable pipes and regulating stops or valves. At the
junction of the two limbs of the syphon a head pipe or cylinder may be
formed and fitted with a self-action rising and falling piston or flexible
diaphragm in order to allow the water to rise and fall therein. The object
of this head pipe or cylinder is to utilize the increased head or height of
the hydraulic column obtained by the motion of the ship, and thus augment
the weight of water upon the turbine, &c., and increase its propelling power.
The first mover or power by which the turbine or other hydraulic motor
is driven may be a steam or other engine. I propose to further increase the
propelling power of the water ejected by the bydraulic motor by fitting a
number of flanges of a helical form in the discharging pipe or cylinder through
which the water is forced into the surrounding fluid. Helical blades may be
mounted upon a horizontal shaft and caused to rotate in the axis of the said
pipe, in either case these flanges or blades acting upon the water passing
through the cylinder cause it to impinge as a rotating column against the water
in the wake of the ship. I propose to form the hydraulic motor with angular
delivering boxes at the periphery or near the circumference in the top of the
bottom covering plate.

EXPLANATION OF THE DRAWING.
Fig. 1 is intended to illustrate the principle upon which I obtain the increase
of propelling power by the introduction of syphons.
(Fig. 1,) A, A¹, is a cylinder or pipe open at both ends, the lower end A¹
being turned or bent to any angle; B, B, the surface of the sea or river, the
tide or current of which is supposed to be running in the direction of the
arrow B', the velocity of the water entering the cylinder or pipe C will
cause the column within it to rise above the surrounding surface, and this
height will vary according as the velocity of the tide or current is increased
or diminished. By inclining the cylinder or tube as shewn by the dotted
lines A the same result will be obtained. Now supposing the surrounding
fluid to be in a quiescent state, and the cylinder or pipe to be moved through
it with a velocity equal to that of the tide or current in the former case the
same result will also be obtained.
Fig. 2 is intended to illustrate the practical application of the foregoing
principle as applied to the propulsion of ships or other vessels.
(Fig. 2). Let A, B, C, D, represent the outline of a ship in longitudinal
section; E, E, the load water line; F, a turbine wheel or hydraulic motor; G,
a cylinder or tube through which the water for propelling the vessel is ejected
at C; this pipe may be a plain cylinder or be fitted internally as before
described; H, H, an induction syphon having a head pipe or cylinder; through
the limb of this syphon the water at K enters when the ship is under way
rising in the cylinder I more or less according as the ship is propelled with a
greater or less velocity. From this cylinder the water falls through the other
limb of the syphon upon the hydraulic moter F, and is thereby driven out
through the pipe G.
Fig. 3 shews a longitudinal section of a vessel as fitted with a hydraulic
motor and induction syphon A, the latter being formed without any head pipe;
the head or bend B of the syphon in this case is raised above the load water
line C, C, and when charged will maintain that condition by the motion of the
ship which will cause the water to ascend above the ordinary level as before
described.
I claim, first, the use and application of syphon-shaped water pipes for
conducting water to or from turbines or other hydraulic motors in ships or
other vessels.
Secondly, the syphou conduit formed with a head pipe or cylinder as herein
described.

page_text: Thirdly, the combination of the said syphon conduits with ordinary shaped
syphons or pipes for conducting water to or from turbines, wheels, or other
hydraulic motors in ships or for other purposes.
In witness whereof, I, the said Richard Robert Loane Rosoman, have
hereunto set my hand and seal, this Fifteenth day of July, in the year
of our Lord One thousand eight hundred and sixty-seven.
