page_text: LETTERS PATENT to Montagu Archdeacon, of 144, York Road, Lambeth,
. in the County of Surrey, for the Invention of "A NEW OR IMPROVED
KIND OF EXPANDING WINDOW BLINDS, CORNICE POLES, BLIND ROLLERS, AND
PROVISIONAL SPECIFICATION left by the said Montagu. Archdeacon
at the Office of the Commissioners of Patents, with his Petition, on.
the 22nd March 1866.
MONTAGU ARCHDEACON, of 144, York Road, Lambeth, in the County of.
Surrey, do hereby declare the nature of the said Invention for "A NEW
OR IMPROVED KIND OF EXPANDING WINDOW BLINDS, CORNICE POLES, BLIND
ROLLERS, AND OTHER WINDOW FITTINGS, ALSO PICTURE RODS AND STAIR Rons," :
to be as follows:-
I claim an expanding window blind suitable for either the bottoms or
tops of windows in houses, carriages, shops, factories, or any building or
vehicle suitable to such blinds.
I also claim the adaptation of the same expansive' principle to cornice
poles, blind rollers, or other window fittings, also picture rods and stair rods.
My Invention consists of two or more frames made of wood, iron, brass, or
other suitable material, and covered with wire gauze, perforated zinc, glass,
or other suitable material. I place the frames one over the other and brace.

page_text: them together, so that one slides over the other and expands to fit any
window or aperture.
I also claim the same expansion by means of one tube sliding into
another.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Montagu Archdeacon in the Great Seal Patent Office on
the 22nd September. 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MONTAGU

One thousand eight hundred and sixty-six, in the twenty-ninth year of Her

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
"A NEW OR IMPROVED KIND OF EXPANDING WINDOW BLINDS, CORNICE POLES, BLIND
ROLLERS, AND OTHER WINDOW FITTINGS, ALSO PICTURE RODS AND STAIR RODS,"
upon the condition (amongst others) that I, the said Montagu Archdeacon,
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 Montagu Archdeacon, do hereby
declare the nature of the said Invention, and in what. manner the same is to
be performed, to be particularly described and ascertained in and by the.
following statement. thereof, that is to say :-
This Invention has for its object the construction of window blinds suitable
for the lower or upper parts of windows, in such manner as to be. capable of

page_text: and other window fittings, also to picture rods and stair rods, each of two or
more parts arranged to slide onc on the other, and used in their contracted
or expanded state according to the particular requirement for the time
being.
DESCRIPTION OF THE DRAWING.
i
Figure 1 shows a window blind constructed of wire gauze framed together
in two parts, and in this Figure the blind is shown in its contracted state;
Figure 2, shows the same blind. in its expanded state
this blind may be
applied to any window of a width not exceeding that shewn at Figure 2, and
not less than that shewn in Figure 1, but to a window of any intermediate
width.. The window blind shown at Figures 1 and 2 is composed of two parts
only, but window blinds may be similiarly made of three parts, as shewn in
Figures 3 and 4, or of more parts. The upper rail of the blind may be
straight or it may be made to a curve, when the parts a, a, of a window blind
consist of wire gauze or perforated metal, or of stained, painted, or other
glass, or of canvass or other like material it is preferred that the framing b, b,
should be of brass or other metal, and it is further preferred that the two
uprights c, c, by which a blind is fixed in a window should be of wood. The
wire or other gauze or material may be plain and of one color, or the same
may be ornamented by painting or otherwise. In the constructions shewn in
the Drawing, the metal framing at b, b, is tubular with projecting lips b¹, b¹,
between which the edges of the gauze or material a, a, is to be fixed securely,
so as to retain it in a flat extended state, and the top and bottom rails of the
framing b, b, are arranged to slide one in the other, as is shown in transverse
section, Figure 5. When a window blind is more or less contracted in width
the parts a, a, will overlap to a greater or less extent, and this overlapping in
the window blind, Figures 1 and 2, will be in the centre of the window, but
where a window blind is composed of three or more parts the overlapping will
be at two or more places, and, therefore, it is desirable in making window
blinds of three or more parts or frames, according to my Invention, that the
parts overlapping should be similar to each other at the different points where
such overlappings come, in order that a uniformity of character may be
obtained, and not a comparatively large overlapping in one part and a
comparatively less overlapping in another part.

page_text: In constructing cornice poles, blind rollers, and other window fittings, also
picture rods and stair rods, each it is preferred should be made of three parts
to slide one into another,in order that the two ends should be of like diameter,
but this is not essential as each may be made of only two parts, one sliding
within the other, the two ends of each such blind roller are to be closed and
to be formed with or arranged to turn on suitable necks or axes.
The two
ends of each such pole or rod are to be formed with such ornamental forms as
may be desired to give them a finished character, and stops may be formed
on the different parts of which such poles or rods are formed, in order to prevent
their being extended beyond what is intended to be their greatest length.
Having thus described the nature of my Invention, and the manner of
performing the same,I would have it understood that I claim the construction
of expanding and contracting window blinds herein described, and I also claim
the construction of expanding and contracting cornice poles, blind rollers,
and other window fittings, also picture and stair rods as-herein described.
In witness whereof, I, the said Montagu Archdeacon, have hereunto
set my hand and seal, this Twenty-second day of September, in the
year of our Lord One thousand eight hundred and sixty-six.
MONTAGU ARCHDEACON. (L.s.)
