PROVISIONAL SPECIFICATION left by the said John Hays Wilson at the
Office of the Commissioners of Patents, with his Petition, on the
21st April 1866.
I, JOHN HAYS WILSON, of the Firm of John Hays Wilson and Company,
of Liverpool, in the County of Lancaster, Brass Founders and Ship's Iron-
mongers, do hereby declare the nature of the said Invention for "AN IMPROVED
APPARATUS FOR THE DISTILLATION OF SEA-WATER ON BOARD SHIPS, AND FOR HEATING
THE FEED-WATER THEREPOB, PARTS OF WHICH ARE ALSO APPLICABLE TO THE HEATING
OF ANY PORTION OF THE VESSEL OR FOR HEATING CONSERVATORIES AND OTHER
BUILDINGS," to be as follows, that is to say:-
This Invention has for its object certain improvements in the apparatus for
distilling sea-water, and for heating the feed-water for supplying the still,
Price 8d.1

page_text: when it is required to distil a larger quantity of water than can be conveniently
done by the galley fire, parts of which apparatus are peculiarly applicable to
the ship's galley stove registered by the firm of the Applicant and known as
"Wilson's registered ship's galley stove."
This Invention consists, first, in forming each side of the fire-place of the
stove with narrow vertical water chambers, extending from a point at or about
in line with the horizontal bars of the fire-place to near the under side of the
top of the hot plate of the cooking range. These vertical water spaces also
form the sides of the ovens nearest the fire and open out at their rear end
into an enclosed water space or vertical boiler up through the centre of which
is carried the flue of the stove, a lateral opening being formed through the
side of the vertical boiler at the back of the stove fire, which opens into the
vertical portion of the flue in the centre of the vertical boiler, and through
which the products of combustion pass when it is not required to heat
one or both of the ovens. The flue opening at the back is fitted with a
damper, by closing which the draught is turned over the ovens, and
carries the products of combustion round them when they escape into the
flue through an opening constructed at a point below the fire-bars.
The
top of the vertical boiler or evaporating vessel is connected to a condensing
worm by a suitable pipe, and the water heated by the condensing worm
may be used as feed-water for the boiler by being connected therewith
and conveyed thereto by a pipe, which may be fitted with a cock or other stop
valve, and the bottom of the condensing worm vessel is also provided with a
draw-off cock or valve for the purpose of conveniently obtaining the partially
heated water for any use that it may be required, or to allow the same to escape
to be replaced by cold water. The condenser may be supplied with its cold
water from a cistern placed in any convenient situation above the apparatus
or by pumps, or in any other convenient manner. When a large quantity of
water is required to be distilled it is preferred to have a continuous stream of
cold water passing through the vessel enclosing the condensing worm, in which
case the galley-fire in itself would be insufficient in its evaporating power, and
to obviate which the second part of this Invention relates, and consists in the
use of and certain improvements in the water boiler known as the saddle
boiler (which nearly resembles a horse-shoe in transverse vertical section), for
heating the water previous to the introduction of the same into the evaporating
vessel to which it is connected by suitable pipes or passages.
The part of this Invention which relates to the improvements in and applic-
able to the saddle boiler consists, first, in constructing the shell and flues
passing therethrough in two or more parts, and connecting them together by

page_text: bolts and nuts, or rivets passing through flanches formed on the edges of the
several sections, the shell and flues being divided in a vertical direction. The
object of this arrangement being a convenient and ready means whereby the
boiler may be enlarged or reduced within certain limits by adding or removing
a central section, as the case may be, and in constructing the boiler with two
horizontal parallel flues running longitudinally through the boiler in a line a
little above the crown of the furnace, also in the construction and use of a
supplementary boiler or chamber for enclosing the rear end of the saddle boiler,
and which supplementary chamber is formed with a hollow foot, the front of
which is turned up at a right angle and constructed with a rectangular water
space which forms the bridge of the furnace and the front or inner surface of
the supplementary chamber is recessed so as to form a flue, into which opens the
rear ends of the two parallel horizontal flues which extend through the saddle
boiler. It is preferred to construct the improved saddle boiler with hollow
fire-grate bars to contain water in communication with the interior of the
boiler, as is well understood. The interior of the saddle boiler, and the interior
of the supplementary chamber on the rear end thereof, are connected together
by means of suitable pipes or passages; the saddle boiler with its supple-
mentary chamber is set in suitable brickwork, and is fired on top of the hollow
bars, the heat passing over the hollow bridge on the front of the supplementary
chamber into the cavity formed on the front or inner face of the chamber and
thence through the horizontal parallel flues of the saddle boiler, and returned
through flues formed in the brickwork on the sides of the boiler into the
take-up of the flue, where it escapes. It will be readily observed that where
only a comparatively small quantity of distilled water is required that this
may be obtained by the aid of the galley stove fire alone, without the use of
the improved saddle boiler and its appendages herein-before described, but
where a large quantity of distilled water is required it will be necessary to use
the second part of the Invention in combination with the first; as by means
of the saddle boiler and its appendages the feed water for the evaporation may
be heated at any desired temperature. And it will be readily seen that the
improved saddle boiler with its supplementary chamber may be used with
advantage to heat water in connexion with a system of pipes for heating the
cabins or any portion of the vessel on board which it may be fitted, and also
that the said improved saddle boiler with its supplementary chamber may be
used with great advantage for heating conservatories or other buildings, as
will be well understood.

upon the condition (amongst others) that I, the said John Hays Wilson
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.
NOW KNOW YE, that I, the said John Hays Wilson, 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 (that is to say):-
This my said Invention has for its object certain improvements in the
apparatus for distilling sea water, and for heating the feed water for supplying
the still when it is required to distil a larger quantity of water than can be
conveniently done by the galley fire, parts of which apparatus are peculiarly

spaces also form the sides of the ovens nearest the fire, and open out at their
rear end into an enclosed water space or vertical boiler, up through the centre
of which is carried the flue of the stove, a lateral opening being formed

the vertical boiler or evaporating vessel is connected to a condensing worm
by a suitable pipe, and the water heated by the condensing worm may be
used as feed-water for the boiler by being connected therewith and conveyed

applicable to the saddle boiler consists, first, in constructing the shell and
flues passing therethrough in two or more parts, and connecting them
together by bolts and nuts or rivets passing through flanches formed on the
edges of the several sections, the shell and flues being divided in a vertical
direction. The object of this arrangement being a convenient and ready
means whereby the boiler may be enlarged or reduced within certain limits

page_text: by adding or removing a centre section, as the case may be, and in con-
structing the boiler with two horizontal parallel flues running longitudinally
through the boiler in a line a little above the crown of the furnace, also in
the construction and use of a supplementary boiler or chamber for enclosing
the rear end of the saddle boiler, and which supplementary chamber is formed
with a hollow foot, the front of which is turned up at a right angle, and con-
structed with a rectangular water space, which forms the bridge of the
furnace, and the front or inner surface of the supplementary chamber is
recessed, so as to form a flue, into which opens the rear ends of the two

mentary chamber on the rear end thereof, are connected together by means of

the flue, where it escapes. It will be readily observed that where only a com-
paratively small quantity of distilled water is required, that this may be
obtained by the aid of the galley stove fire alone without the use of the
improved saddle boiler and its appendages herein-before described; but where
a large quantity of distilled water is required, it will be necessary to use the
second part of this Invention in combination with the first, as by means of the
saddle boiler and its appendages the feed water for the evaporation may be
heated to any desired temperature. And it will be readily seen that the
improved saddle boiler with its supplementary chamber may be used with

cabins, or any portion of the vessel on board which it may be fitted, and also
that the said improved saddle boiler with its supplementary. chamber may be
used with great advantage for heating conservatories or other buildings, as
will be well understood.
That this my said Invention may be the more readily seen and understood,
I have hereunto annexed Drawings illustrating so much of my Invention as is
necessary to show the practical application of the same. like letters and
Figures marked thereon being used to denote similar parts:
Figure 1 is a vertical sectional elevation of the galley stove with my

Z and Z', outlet and inlet pipes. The supply pipe Z' (Figure 5) is shown
broken off, but in practice is connected to a cistern or other source of supply.
and when used in combination with the improved apparatus connected to the
galley stove, the outlet pipe Z (Figures 4 and 5) are connected with the
upright boiler of the galley stove; or when used for heating cabins, con-
servatories, or other buildings, is connected with a system of pipes, as is well
understood.
Having now fully described and ascertained the nature of this my said
Invention, and the best means I am acquainted with for carrying the same
into practical effect, I wish it to be understood that I do not confine myself
to the relative proportions or dimensions of the several parts herein-before
described and set forth, as it will be readily seen that the same may be con-

page_text: siderably varied without departing from the Invention; but what I claim as
new and my Invention is,-
First, the peculiar form of the upright boiler with the lateral water
chambers forming the sides of the furnace grate, and passing the products
of combustion through the uptake or flue formed in through the centre of
the upright boiler, as applied to galley stoves for the distillation of sea water,
substantially in the manner and for the purposes herein-before described and
set forth.
Secondly, forming or casting the upright boiler with the lateral water
chambers forming the sides of the oven and furnace grate with the vertical
flue and flue openings in one piece, substantially in the manner and for the
purposes herein-before described and set forth.
Thirdly, forming a horse-shoe boiler by castings in sections, substantially
in the manner and for the purposes herein-before described and set forth.
Fourthly, the peculiar form and use of the back water space V with its
water chamber, foot and toe-piece forming the bridge of the furnace.
Fifthly, the use of the double parallel longitudinal flues extending through
the boiler over the crown of the furnace.
Sixthly, casting the parallel flues and front plates of saddle boilers in one.
piece with the parallel flues, substantially in the manner and for the purposes
herein-before described and set forth.
And, lastly, the peculiar arrangement and form and mode of connecting the
several parts forming an improved saddle boiler, substantially in the manner
and for the purposes berein-before described and set forth.
In witness whereof, I, the said John Hays Wilson, have hereunto set
my hand and affixed my seal, this Nineteenth day of October, in the
year of our Lord One thousand eight hundred and sixty-six.
