of Middlesex, Patent Agent, for the Invention of "IMPROVED IRON
BLINDS." A communication from abroad by Marie Colombe Duclos, of

PROVISIONAL SPECIFICATION. left by the said Charles Stevens at the
Office of the Commissioners of Patents, with his Petition, on the 27th
February 1861.
I, CHARLES STEVENS, of 31, Charing Cross, in the County of Middlesex,
Patent Agent, do hereby declare the nature of the said Invention for "IMPROVED
IRON BLINDS," & that it has been communicated to me from abroad by Mdo.
Duclos, of No. 42, Rue Laffitte, Paris, in the Empire of France, to be as
follows:
The blinds are made of straight laminated iron blades, the sectional form of
which is that of an S; the hips or corners are rounded by action of the rolling
mill. The apparatuses used in the manufacture are a rolling mill, a swing
lever, a mould for piercing the holes of the uprights, a mould for piercing
the holes of the screen boards, and an elbowed punch for riveting. The im
proved iron blind besides being of a lower price than one of wood is much more
elegant and light in appearance; it is also more durable, and the small space
it occupies permits of it being placed in the thickness of the wall.

NOW KNOW YE, that I, the said Charles Stevens, 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 and accompanying Drawings, that is to say :-
My Invention consists of an improvement in blinds or shutters whereby
increased elegance of appearence, greater durability, lightness, and a consider-
able reduction in price, is obtained. These results are effected by substituting
laminated iron for the wood hitherto employed..
. The manufacture is extremely simple, the only machine or tools required
being a rolling mill, a swing lever, a mould for piercing holes in the uprights;
a mould for piercing holes in the screen boards, and a riveting punch.
The iron, without being heated, is subjected to the action of the rolling mill,

Fig. 2, C, represents the back uprights which form the sides of the frame.
Fig. 6, D, shows the piece serving either as top or bottom back part of the
frame.
Fig. 5, A, represents a piece of iron undulating from side to side in form,
and which is riveted to the upright C, Fig. 2.
Fig. 7, D, outside bottom or top piece having the form of the piece A,
Fig. 5; it is fixed by rivets to the piece D.
Fig. 1 shows a sectional view of the shutter.
Figs. 3 & 4 represent the shutters when finished. B are the screen boards,
also of iron, and either undulating in shape or not; the edges of the iron are
rounded in the rolling mill, so that all danger to the hands is avoided.
Having thus described my Invention, what I claim and desire to secure by
Letters Patent is, the substitution of iron, laminated while cold, for wood,
hitherto used in the manufacture of shutters or blinds, in the manner and for
the purposes above described and represented in the accompanying Drawings.
In witness whereof, I, the said Charles Stevens, have hereunto set my
hand and seal, this Twenty-seventh day of August, in the year of our
Lord One thousand eight hundred and sixty-one.
CHARLES STEVENS. (L.S.)
