page_text: LETTERS PATENT to William Henry Graveley, of Upper East Smithfield,
in the County of Middlesex, Manufacturer, for the Invention of
**IMPROVEMENTS' IN' STEAM MACHINERY' AND SEA WATER DISTILLING APPA-
""RATUS, ALL FOR USE ON BOARD SHIP:"
PROVISIONAL. SPECIFICATION left by the said William Henry Graveley
at the Office of the Commissioners of. Patents, with his Petition, on ther
30th September 1864.
I; WILLIAM HENRY: GRAVELEY, of Upper East Smithfield, in the County.
of. Middlesex, Manufacturer; do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN STEAM MACHINERY AND SEA WATER DISTILLING. APPARATUS;
ALL, FOR: USE. ON. BOARD: SHIP," to be as follows:-
My. Invention consists in combining steam machinery and sea water' dis-
tilling apparatus in manner hereafter.described:
I place upon a.condenser for condensing steam. from a boiler supplied with.
sea or other water one or a pair of steam cylinders; and connect: the plunger
of a pump with the piston cross head. The pump. is made to draw and force.
water into and through. the. condenser:. I apply an air dome, and when
required the pump may be used as a fire engine, or for pumping water: to
cleanse:decks and. closets. and for wetting the sails as may be required On
the crank shaft I key two wheels with broad tyres or hoops, and carry belts

page_text: from them, or one of them, to drive a fan for ventilating the ship; I also key
on the crank shaft a toothed pinion which gears into a toothed wheel on a
shaft over the main hatch; this shaft is used for hoisting cargo into and out
of the ship. On both sides of the machine this shaft carries a barrel and a
chain wheel; one chain wheel communicates motion through a chain to the
ship's pumps and "the other to the windlass, while the barrels serve for
hoisting sails, warping the ship, and other similar purposes.
The engines may be worked as condensing or high-pressure, when as con-
densing, the waste steam from the cylinders enters the condenser, and the
condensed water is aërated and passed through a filter, as in the Specification
of Letters Patent, No. 1320, granted to me 28th May, 1859. .
I generally use a steam cooking apparatus in conjunction with the com-
bined machinery herein-before described, and lead the steam employed to
heat the cooking apparatus into the condenser.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Graveley in the Great. Seal Patent Office
on the 30th March 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY GRAVELEY, of Upper East Smithfield, in the County of Middlesex,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of September, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of 'Her
reign, did, for Herself, Her heirs and successors, give, and grant unto me, the
said William Henry Graveley, Her, special licence that I, the said William
Henry Graveley, my executors, administrators, and assigns, or such others as]
I, the said William Henry Graveley, 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 "IMPROVE-
MENTS IN STEAM MACHINERY AND SEA WATER DISTILLING APPARATUS, ALL FOR USE
ON BOARD SHIP," upon the condition (amongst others) that I, the said
William. Henry Graveley, my executors or administrators, by an instru-
ment 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..

page_text: 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.imme-
diately after the date of the said Letters Patent
NOW KNOW YE, that I,. the said William Henry Graveley, 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 fol-
lowing statement thereof, reference being had to the Drawings, hereunto
annexed, that is to say:-
My Invention. consists in, combining steam machinery and sea water dis-
tilling apparatus in manner hereafter described and represented in the
accompanying Drawings.
Figure 1 is a plan, and Figure:2 an elevation of the combined machinery
and apparatus; Figure 3 is a section through the line a, b Figure 4, a
section through the line j, h; and Figure 5, a section through the line c, d,
of Figure 1.
I place upon a condenser A for condensing steam from a boiler supplied
with sea or other water, one or a pair of steam cylinders B, and connect the
plunger C of a pump with the piston cross head D (Figure 1). The pump
is made to draw and force water into and through the condenser A. I apply
an air dome E, and when required the pump may be used as a fire engine or
for pumping water to cleanse decks and closets and for wetting the sails as
may be required, and for these purposes a nozzle may be fitted, as shewn
at P. On the crank shaft I I key two wheels G, G, with broad tyres or hoops,
and carry belts from them or one of them to drive a fan H for ventilating the
ship; I also key on the crank shaft I a toothed pinion J, which gears into a
toothed wheel K on a shaft L over the main hatch; this shaft is used for
hoisting cargo into and out of the ship. On both sides of the machine this
shaft carries a barrel M and a chain wheel O' and 02. The chain wheel O.
communicates motion through a chain to the ship's pumps, and the other
wheel O to the windlass, while the barrels M serve for hoisting sails,
warping the ship, and other similar purposes.
;
The engines may be worked as condensing or high-pressure by means of
the cock P; when as condensing, the waste steam from the cylinders enters
the condenser A, and the condensed water is aërated and passed through a
filter Q, Figure 5, as in the Specification of Letters Patent, No. 1320, granted
to me 28th May, 1859.
I generally use a steam cooking apparatus in conjunction with the com-
bined machinery, herein-before described, and lead the steam employed to heat
the cooking apparatus into the condenser A.

page_text: And having now described: the, 'nature of my said- Invention, and in what
manner: the same is to be performed, Iideclare that I claim combining steam
machinery and sea water distilling apparatus for use on board ship, in
manner herein-before described and illustrated in the accompanying
Drawings.
In witness whereof, I, the said William Henry Graveley, bave hereunto
set my hand and seal, this Thirtieth day of March; One thousand
eight handund and siste fue
