WHEREAS er present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Fifteenth day of August, in the seventh year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Archi-
bald Horn, Her especial licence, full power, sole privilege and authority, that
1, the said Archibald Horn, my exors, adñiors, and assigns, or such others as
I, the said Archibald Horn, my exors, adiñors, or assigns, should at any
time agree with, and no others, from time to time and at all times, during the
term of years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTERS FOR WIN-
DOWS AND FOR OTHER PURPOSES;" in which said Letters Patent is contained a
proviso that I, the said Archibald Horn, shall cause a particular description
of the nature of my said Invention, and in what manner the same is to
be performed, to be inrolled in Her said Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said
in part recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Archibald Horn, do hereby declare that the nature of my Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say-

page_text: My Invention consists of improvements in sliding shutters, whereby they
are caused to succeed each other into position in the same groove at either
end, by which much less space is occupied when the shutters are covering a
window or other opening than similar shutters heretofore used (where each
moved in its own separate grooves) have required.
And in order that my Invention may be fully understood and readily carried
into effect, I will proceed to explain the Drawings hereunto annexed, in the
various Figures of which the same letters are used to indicate similar parts.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews the front view of a shop window having my improvements
applied thereto; Figure 2 is a longitudinal section; Figure 3 is a vertical
section; Figure 4 shows a back view of the shutters, with suitable apparatus
for moving the same, shown separately, for a window or other opening;
Figures 5, 6, 7, show some of the parts separately on a larger scale, in order
that the construction of the parts may be more clearly shewn. a, b, b, are the
sliding shutters, the lower one a is that by which the others are moved up and
down, and it differs at its lower edge from the others b, b, by its having the
bar c affixed thereto, as is shown; at the ends of which bar are applied female
screws d, which embrace the screws e, e; consequently, when the screws e, e,
are turned, the lower shutter a will be moved up or down, according to the
direction in which those screws e, e; are turned. The shutters b, b, are similar
to each other, and more or less of them are used according to the size of the
window or other opening to which the shutters are applied, and according to
the width of shutters which can conveniently be used. f, f, are two grooves,
one on each side of the window or opening; and at the upper part thereof
is formed the chamber g, into which the shutters b, b, are successively raised
by the shutter a, and from which they are successively drawn into the same
groove f, on either side of the window, and in such manner that when
all the shutters are down, they will, with the exception of the joints, offer one
plane or level surface, the shutters being one above the other, as shown in
the Drawing. The shutters are of sheet metal, strengthened at their ends (or
they may be made of other suitable material), as shown in the Drawings;
and they are so formed as to take hold of each other as they descend out of
the chamber 9: and they form covered joints which cannot be separated or
opened. The forms of these joints and connections which are shewn are those
which I prefer, but they may be varied, the workman taking care that the
parts are so formed that in going up towards the chamber g they will be
forced successively into the chamber g, and be in such a position that they
may successively be caused to descend by each shutter drawing the next one

page_text: above after it into the same groove f, f. Motion is communicated to the
screws e, e, (which are suitably formed and applied for causing the two ends
of the shutter to move up or down at the same speed, as is well understood,
and separately form no part of my Invention; and other means may be
resorted to for moving shutters arranged and constructed according to my
Invention,) by means of the handle h, the axis of which is carried by a
suitable bearing, and on its axis is affixed a bevil toothed wheel i, which takes
into and drives the bevilled toothed wheel j on one of the screws e. The
wheel takes into and drives the bevilled toothed wheel affixed on the
axis 1, which turns in suitable bearings, as shown. m is a bevilled toothed
wheel affixed on the axis l, which takes into and drives the toothed wheel n
affixed on the other screw e.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would remark, that I make no claim to
any of the parts separately; and it will be evident, that by a slight modifica-
tion of the parts, the shutters may be caused to move in other directions than
that shown. Nor do I confine myself to the precise details, so long as the
peculiar character of my Invention is retained. But what I claim is, the
mode herein described of constructing and combining shutters, whereby they
are caused successively to move into and out of the same grooves, and when
closing a window or other opening, they are in the same grooves and in the
same plane or nearly so, as above described.
In witness whereof, I, the said Archibald Horn, have hereunto set my
hand and seal, this Fifteenth day of February, in the year of our Lord
Oue thousand eight hundred and forty-four.
