IMPROVEMENTS IN WINDOW SHUTTERS.
Year: 1869

page_text: LETTERS PATENT to Samuel Jackson, of Bradford, in the County
of York, Architect, for the Invention of "IMPROVEMENTS IN WINDOW
SHUTTERS.'
Sealed the 19th November 1869, and dated the 21st May 1869.
PROVISIONAL SPECIFICATION left by the said Samuel Jackson at
the Office of the Commissioners of Patents, with his Petition, on
the 21st May 1869.
I, SAMUEL JACKSON, of Bradford, in the County of York, Architect,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN WINDOW SHUTTERS," to be as follows:-
This Invention consists in constructing window shutters of laths or
narrow strips of wood, or other suitable material arranged horizontally
and binged together, the joints being on alternate sides so as to allow
them to fold in a zig-zag manner one upon another. A box or receptacle
is also formed or provided under the window bottom hetwixt the masonry
and the lining of suitable dimensions to receive and contain the said
shutters when folded. A cord or chain is fixed to each end of the top

page_text: lath, which cords are thence passed respectively over pullies fixed in the
top of the window casing or frame, and are attached to balance weights
behind in a similar manner to the usual mode of hanging window sashes,
and grooves are formed in the casing on each side of the window to
guido and retain the said shutters in position. When the shutters are
lowered into the box a lid is closed upon them in the same manner as
with ordinary slide shutters.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Jackson in the Great Seal Patent Office
on the 20th November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
JACKSON, of Bradford, in the County of York, Architect, send
greeting.
WHEREAS ITer most Excellent Majesty Queen Victoria, by Her
Letters Patent, hearing date the Twenty-first day of May, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, er heirs and successors,
give and grant unto me, the said Samuel Jackson, Her special licenco
that I, the said Samuel Jackson, my executors, administrators, and
assigns, or such others as I, the said Samuel Jackson, 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
WINDOW SHUTTERS," upon the condition (amongst others) that I, the
said Samuel Jackson, any executors or administrators, by an instrument
in writing under my, or thoir, 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 Samuel Jackson, do hereby declare
the nature of my said Invention, and in what manner the same is

page_text: to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Sheet of Drawings (that
is to say):
This Invention consists in constructing window shutters of laths or
narrow strips of wood, or other suitable material arranged horizontally
and hinged together, the joints being on alternate sides so as to allow
them to fold in a zig-zag manner one upon another. A box or receptacle
is also formed or provided under the window bottom betwixt the
masonry and the lining of suitable dimensions to receive and contain
the said shutters when folded. A cord or chain is fixed to each end of
the top lath, which cords are thence passed respectively over pullies fixed
in the top of the window casing or frame, and are attached to balance
weights behind in a similar manner to the usual mode of hanging
window sashes, and grooves are formed in the casing on each side of the
window to guide and retain the said shutters in position. When the
shutters are lowered into the box a lid is closed upon them in the same
manner as with ordinary slide shutters.
This Invention will be readily understood by reference to the accom-
panying Sheet of Drawings, wherein Figure 1 is an elevation or interior
view of a window and the framework thereof with my improved
shutters applied, and in the raised position; Figure 2 is a vertical
section, and Figure 3 is a horizontal section of the same. A is the
shutter, which is composed of a series of laths or narrow boards
hinged together so as to fold one upon another, as will be clearly seen
in the detail Drawing, Figure 4, which is drawn full size. In Figure 2
the shutter is shewn in its folded state in the box B formed between the
masonry and the ordinary lining below the window bottom, and also is
shewn one of the grooves C to guide and retain the shutter when raised;
an ordinary sash cord or chain being attached to each end of the top
lath passing over pullies D fixed in the casing and connected to balance
weights E, seen in Figure 3, in a similar manner to the usual mode of
hanging window sashes. As however these weights can only be made
to balance the shutter when it is in the raised position (the weight of
the shutter being variable according to its being more or less folded,
which will be obvious), consequently these shutters will rise by the
pressure or force of the weights; but to lower them into the box they
require to be forced down, and to retain them therein a lid F is hinged
to the lining, which can be closed upon them and secured by any

page_text: ordinary kind of latch or fastener. To ensure the proper folding of
the laths composing this shutter in the box I fix two or more antifriction
rollers in the bottom edge of the bottom lath, as shown at G, Figure 4,
so that it will move easily into the horizontal position when pressed
against the bottom of the box.
Having thus described the nature of the said Invention, and shewn
by Drawings how the same is or may be performed or put into practice,
I would have it understood that I do not confine myself to the precise
details of construction and application shewn and described, as various
modifications therein will necessarily have to be made according to
circumstances; but what I claim as my Invention is the constructing
and applying window shutters so as to fold horizontally, in manner sub-
stantially as shewn and described.
In witness whereof, I the said Samuel Jackson, have hereunto
set my hand and seal, this Eighteenth day of November, in the
vear of our Lord One thousand eight hundred and sixty-nine.
Signed, sealed, and delivered by
the within-named Samuel
Jackson, in the presence of
W. TASKER,
Patent Agent,
Halifax & Bradford.
