IMPROVEMENTS IN SUPPLYING WATER TO SURFACE CONDENSERS OF MARINE ENGINES
Year: 1863

page_text: LETTERS PATENT to Edward Hayes, of Stoney Stratford, in the County
of Bucks, for the Invention of "IMPROVEMENTS IN SUPPLYING WATER TO
SURFACE CONDENSERS OF MARINE ENGINES."
Sealed the 21st August 1863, and dated the 28th February 1863.
PROVISIONAL SPECIFICATION left by the said Edward Hayes at the
Office of the Commissioners of Patents, with his Petition, on the
28th February 1863.
I, EDWARD HAYES, of Stoney Stratford, in the County of Bucks, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN SUPPLYING WATER
TO SURFACE CONDENSERS OF MARINE ENGINES," to be as follows:-
This Invention has for its object improvements in supplying water to
surface condensers of marine engines. For these purposes in constructing and
arranging surface condensers on board ships or vessels propelled by screw or
submerged propellers, the outer ends of the outlet pipes of the surface
condensers are placed near the screw or submerged propellers. The supply of
water to the surface condensers is by pipes passing through the ships or
vessels, so as to admit of a free flow of water to the surface condensers. By
thus constructing and arranging the surface condensers of marine steam engines,
the action of the submerged or screw propeller will cause the condensing
water to be constantly removed from the outlet ends of the outlet pipes of the

page_text: surface condensers, and the pumps heretofore employed to facilitate the
passage of condensing water through the surface condensers may be dispensed
with.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Hayes in the Great Seal Patent Office on the
28th August 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
HAYES, of Stoney Stratford, in the County of Bucks, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of February, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Edward Hayes, Her special licence that I, the said Edward Hayes, my
executors, administrators, and assigns, or such others as I, the said Edward
Hayes, 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 SUPPLYING
WATER TO SURFACE CONDENSERS OF MARINE ENGINES," upon the condition
(amongst others) that I, the said Edward Hayes, my executors or adminis-
trators, 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 Edward Hayes, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say:-
This Invention has for its object improvements in supplying water to
surface condensers of marine engines. For these purposes in constructing and
arranging surface condensers on board ships or vessels propelled by screw or
submerged propellers, the outer ends of the outlet pipes of the surface
condensers are placed near the screw or submerged propellers. The

page_text: supply of water to the surface condensers is by pipes passing through the
ships or vessels, so as to admit of a free flow of water to the surface
condensers. By thus constructing and arranging the surface condensers of
marine steam engines, the action of the submerged or screw propellers will
cause the condensing water to be constantly removed from the outlet ends of
the outlet pipes of the surface condensers, and the pumps heretofore employed
to facilitate the passage of condensing water through the surface condensers
may be dispensed with.
In carrying out this Invention any description of surface condenser may be
employed which requires a constant current of condensing water flowing to
and from it; the condenser is placed below the water line of the ship or
vessel, so that a current of water may flow readily to it, the inlet pipe
passing out of the vessel below the water line. When a screw propeller
is used the outlet pipe is led to the stern of the ship or vessel, so that its end
comes in front of the screw propeller, and is by preference brought to a point
below that at which the screw shaft passes from the vessel. The partial
vacuum caused by the action of the screw propeller will constantly draw a
current of water through the outlet pipe from the condenser, and thus allow a
constant stream of water to flow into the condenser through the inlet pipe.
In witness whereof, I, the said Edward Hayes, have hereunto set my
hand and seal, this Twenty-fifth day of August, in the year of our Lord
One thousand eight hundred and sixty-three.
EDWARD HATES.
