IMPROVEMENTS IN VENTILATING BLINDS OR SCREENS, AND IN MEANS OF VENTILATING SHIPS AND VESSELS
Year: 1865

page_text: LETTERS PATENT to Charles Lungley, of Deptford, in the County of Kent,
Ship Builder, for the Invention of "IMPROVEMENTS IN VENTILATING BLINDS
OR SCREENS, AND IN MEANS OF VENTILATING SHIPS AND VESSELS."
Sealed the 11th August 1865, and dated the 15th February 1865.
PROVISIONAL SPECIFICATION left by the said Charles Lungley at the
Office of the Commissioners of Patents, with his Petition, on the 15th
February 1865.
I, CHARLES LUNGLEY, of Deptford, in the County of Kent, Ship Builder, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN VENTI-
LATING BLINDS OR SCREENS, AND IN MEANS OF VENTILATING SHIPS AND VESSELS," to
be as follows:
My Invention consists in constructing blinds or screens with alternate fixed
and movable laths or battens, or with part of the battens fixed and part
movable, as represented in Figures 1 to 5 of the accompanying Drawings, in
which a, a, are the fixed and b, b, the movable battens.
I construct the battens of such shapes that when entirely open the air shall
not have direct access through the screen, while the air admitted may be
regulated by causing the movable battens to move or slide, and more or less
close the apertures between the battens.
For ventilating ships I fit ventilators at the bottoms of cabins in the form of
a trunk or pipe, with openings therein fed by air, made in some cases to pass in
tubes through refrigerators or tanks made to communicate by pipes with the
sea or external water, so as to allow of circulation therein of water from the

page_text: sea, or in cases of paddle-wheel boats through a refrigerator placed in the
paddle box or a place near thereto. In some cases I employ a pump or fan
to drive the air through the refrigerating tubes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Lungley in the Great Seal Patent Office on the
15th August 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
LUNGLEY, of Deptford, in the County of Kent, Ship Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of February, 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 Charles Lungley, Her special licence that I, the said Charles
Lungley, my executors, administrators, and assigns, or such others as I, the
said Charles Lungley, 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 "IM-
PROVEMENTS IN VENTILATING BLINDS OR SCREENS, AND IN MEANS OF VENTILATING
SHIPS AND VESSELS," upon the condition (amongst others) that I, the said
Charles Lungley, 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 Charles Lungley, 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 thereof, reference being bad to the Drawings hereunto annexed, that
is to say:
My Invention consists in constructing blinds or screens with alternate fixed
and movable laths or battens, or with part of the battens fixed and part
movable, as represented in Figures 1 to 14 of the accompanying Drawings, in
which a, a, are the fixed and b, b, the movable battens.

page_text: I construct the battens of such shapes that when entirely open the air shall
not have direct access through the screen, while the air admitted may be.regu-
lated by causing the movable battens to move or slide and more or less close
the apertures between the battens.
Figure 15 is a perspective view of a blind constructed according to my
Invention, showing the manuer in which the battens b, b, may be moved.
The movable battens b, b, are held in a frame c, c, to which a cord is connected;
when the cord is pulled, the frame c and movable battens are raised, so that
each of the movable battens closes or partly closes the space between two of
the fixed battens a, a; when the cord is released the frame c, c, and the
battens 6 fall to their original position.
For ventilating ships, I fit ventilators at the bottom of cabins in the form of
a trunk or pipe with openings therein, and fed by air made in some cases to
pass in tubes through refrigerators or tanks made to communicate by pipes
with the sea or external water, so as to allow of circulation therein of water
from the sea, or in cases of paddle-wheel boats through a refrigerator placed
in the paddle box or a place near thereto. In some cases I employ a pump
or fan to drive the air through the refrigerating tubes.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, constructing ventilating blinds or screens, substantially as herein-
before described, with alternate fixed and movable laths or battens, or with
part of the laths or battens fixed and part movable, and of such shapes that
when entirely open the air shall not have direct access through the blind or
screen.
Second, ventilating ships and vessels, substantially by the means and in
manner herein-before described.
In witness whereof, I, the said Charles Lungley, have hereunto set my
hand and seal, this Fifteenth day of August, One thousand eight
hundred and sixty-five.
CHARLES LUNGLEY.
