Year: 1865

page_text: LETTERS PATENT to Henry Edmonds, residing at Peel Lodge, Gosport,
County of Southampton, for the Invention of "IMPROVEMENTS IN APPARATUS
FOR LIGHTING AND VENTILATING SHIPS, PART OF WHICH IS ALSO APPLICABLE
POR PRODUCING FRESH WATER AT SEA."
Sealed the 3rd October 1865, and dated the 7th April 1865.
PROVISIONAL SPECIFICATION left by the said Henry Edmonds at the
Office of the Commissioners of Patents, with his Petition, on the
7th April 1865.
I, HENRY EDMONDS, residing at Peel Lodge, Gosport, County of South-
ampton, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR LIGHTING AND VENTILATING SHIPS, PART OF WHICH IS
ALSO APPLICABLE FOR PRODUCING FRESH WATER AT SEA," to be as follows:-
My improvements consist, 1st, in constructing a tubular apparatus to
extend around or partly around the ship between the decks, having a branch
pipe communicating with the chimney of each lamp required to carry off the
products of combustion and to assist in the ventilation of the ship. This
tubular apparatus is connected by means of a branch tube or tubes with an
updraft ventilator or ventilators.

page_text: 2nd. This may be any of the ordinary ventilators at present in use, such as
the funnel in steam vessels, iron mnasts, galley chimney, or tube and cowl
ventilators.
3. I prefer to create the necessary constant updraft, and at the same time
to produce fresh water, to insert in an ordinary ventilator either a steam
condensing vessel supplied with steam from a boiler, and, having tubular or
other air passages passing through it, or a coil of metal tubing through which
the steam may pass for the same purpose, and is condensed by the cold air
passing through the ventilator, which is also drawn through the air passages
in the condenser or between the coils of metal tubing into usable water.
4th. When I wish to increase the ventilation still further I use a number of
minute steam jets passing up the air passages in the condensing vessel,
between the coils of steam tubing or through a series of tubes subdividing the
area of the ventilator or independantly.
5. Ordinary lamps or other lighting media may be used in connexion with
my apparatus, but I prefer to use a hydrocarbon lamp, in which the fluid
for burning is kept always at the same level on the principle patented by
me (provisionally), No. 3178, in the year 1864, in which the reservoir for oil
has a separate inlet for air at the level of the outlet.
I claim as my Invention the general system for lighting and ventilation
combined, above described; also the apparatus connected with it, and its use
for condensing steam on board of ships; also the means for increasing
ventilating power in the 3rd and 4th paragraph.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Henry Edmonds in the Great Seal Patent Office on the
6th October 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
EDMONDS, residing at Peel Lodge, Gosport, County of Southampton, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of April, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Edmonds, Her special licence that I, the said Henry
Edmonds, my executors, administrators, and assigns, or such others as I, the

page_text: said Henry Edmonds, 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 "IMPROVE-
MENTS IN APPARATUS FOR LIGHTING AND VENTILATING SHIPS, PART OF WHICH IS
ALSO APPLICABLE FOR PRODUCING FRESH WATER AT SEA," upon the condition.
(amongst others) that I, the said Henry Edmonds, 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 Henry Edmonds, 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:-
My improvements consist, first, in constructing a tubular apparatus to
extend around or partly around the sides of the mess or cabin decks of a ship
at as high a level as it can conveniently be placed. The diameter of the tube
should be from 3 to 6 inches, according to the number of lights required,
about one square inch for each lamp. The lamps should be stationery
beneath this tubular apparatus, each fixed in its place and provided with a
chimney. I prefer to use a square lanthorn to fit over the lamp, having a
metal chimney, the Janthorn to be three sides glazed and one side reflecting.
Above each lamp a small branch tube about 1 inch in diameter should lead
downwards from the side tube already described to near the level of the top of
the chimney of the lamp, and it should be provided with a sliding continuation
to fall and fit closely over it, thus establishing a direct communication between.
the lamp or lighting medium and the side tube, into which all the heat and
vapours of the lamps must pass; to carry these off the side tube or tubes
must be communicated into one or more updraft ventilators; these may be
any
of the ordinary ventilators at present in use, as the funnel, hollow iron
masts, the galley funnel, or tube ventilators.
Second, where tube ventilators are used to create the necessary con-
stant updraft, and to increase their ventilating action on the between-decks,
I insert a steam condensing vessel supplied. by a pipe with steam from a
boiler into the lower part of the ventilator, having tubular or other air passage
passing through it occupying the greater part of its area. The steam sur-

page_text: rounds these air passages, and the air being thus heated and rarefied rises
rapidly, and a constant up-current is created, and a larger quantity of the
foul air of the decks will also be drawn through these air passages in the
condensor, this, together with the vapours of the lamps, will by abstracting
heat from the steam condense it into fresh water, which flows out through
a pipe at the bottom of the condensor.
:
Third, the motion of the air through the heated air passages for ventilation
and for the increased condensation of steam may be accelerated by the use of
a fan or other air forcing means, such as by directing a number of minute
steam jets up the ventilator, which I find the most effectual when acting
above the condensor.
Fourth, for lighting in connection with my apparatus any kind of lamp or
lighting medium may be used, but I prefer to use a hydrocarbon lamp,
such as Hinks' Patent.
In the accompanying Drawing Fig. 1 represents an elevation of a portion
of a ship's side internally, the deck space to be lighted extending between (p.
and p¹); the upper and lower deck plankings (9) and (q¹) shew sections of the
beams which support them. (a) the lamp secured to the shelf (i); (b) the
lanthorn fitting over it with its funnel connected with the tube (9) by the
sliding part (h); the tube (9) joins the main side tube (e) which leads into
the updraft ventilator (d) by the cross tube (a), and the heated air and
vapours pass up it and are discharged at the openings in (e); the mess tables,
as in troop ships, are marked (1).
Fig. 2 shews a section of the same deck, the letters corresponding with the
above; the cross shaft (a:) is shewn leading to the updraft ventilator; the
lamp (a) is here shewn enclosed in dotted lines to represent a casing which
might surround and isolate it so that all the air which the lamp consumes
shall be drawn through a tube (w) also shewn in dotted lines leading to an
enclosed list piece or passage over it such as my Patent side tube for venti-
lating ships (No. 585 in 1863); by this all the air required for combustion
in the lamps would pass through the ship's framework from the hold and the
upper part of the mess deck by means of the timber spaces; the course of the
current is shewn by the arrows.
Fig. 3 is an enlarged sketch of the updraft ventilator which I prefer to use;
(f) is the condensor for heating and rarefying the air which is placed in its
lower part, and is to be supplied with steam by the pipe (m), which must be
in communication with a boiler. The air passes up the tubular passages (t);
at (r) is a large sliding door to be opened for ventilating the decks.
Fig. 4 is an enlarged plan of the heating condensor.

page_text: Fig. 5 an enlarged sketch of the kind of lamp I prefer to use, the lettering
as above.
I claim as my Invention the general system of lighting combined with
ventilation described in this Specification, and delineated in the Drawing;
also the [apparatus for creating an updraft and for condensing steam into
usable water when used in connection with it for ventilating purposes on
board of ships.
In witness whereof I, the said Henry Edmonds, have hereunto set my
band and seal, this Sixth day of October, in the year of our Lord One
thousand eight hundred and sixty-five.
HENRY EDMONDS. (L.s.)
