AN IMPROVEMENT APPLICABLE TO OUTSIDE OUR DEADS
Year: 1860

page_text: LETTERS PATENT to Joseph Lewtas, of Manchester, in the County of
Lancaster, Manufacturer of Venetian and other Blinds, for the Invention
of "AN IMPROVEMENT APPLICABLE TO OUTSIDE OUR DEADS
Sealed the 17th October 1860, and dated the 21st April 1860.
PROVISIONAL SPECIFICATION left by the said Joseph Lewtas at the
Office of the Commissioners of Patents, with his Petition, on the
21st April 1860.
I, JOSEPH LEWTAS, of Manchester, in the County of Lancaster, Manu-
facturer of Venetian and other Blinds, do hereby declare the nature of the
said Invention for "AN IMPROVEMENT APPLICABLE TO OUTSIDE SUN BLINDS," to
be as follows:-
My Invention relates to that description of sun blinds which are used
outside windows, the lower end of which is attached at each side to hinged
rods furnished with a slide or "runner," and sliding up and down vertical rods
at each side of the window casement, such jointed rods or stretchers extending
in horizontal position when lowered.
My improvement consists in the novel application and use of two light rods
or bars secured together at their ends, the fabric of the blind passing between
these bars, so that their weight confines the loose blind to the lowest vertical
point or line, that is, at the elbow or joint of the hinged rods, where the rods
and blind are to be secured by connecting or attaching the said double rods to

page_text: the sliding ferrule or "runner" of the jointed rods, thus forming the "hood
or bonnet of the blind at about a right angle with the vertical portion of the
blind, or that which is flat against the window, whereby the extra corner
pieces usually are dispensed with, or the same effect may be obtained by the
use of one rod fixed in the position of the double rods to confine the blind at
the required place.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Lewtas in the Great Seal Patent Office on the
20th October 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
LEWTAS, of Manchester, in the County of Lancaster, Manufacturer of Venetian
and other Blinds, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of April, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Lewtas, Her special licenso that I, the said Joseph Lewtas,
my executors, administrators, and assigns, or such others as I, the said
Joseph Lewtas, my executors, administrators, and assigns, should at any time
ngree with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exer-
cise, and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVEMENT
APPLICABLE TO OUTSIDE SUN BLINDS," upon the condition, amongst others, that
I, the said Joseph Lewtas, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, 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 Joseph Lewtas, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-
My Invention relates to that description of sun blinds which are used out-
side windows, the lower end of which is attached at each side to hinged rods
furnished with a slide or "runner," and sliding up and down vertical rods at

page_text: each side of the window or casement, such jointed rods or stretchers extending
in a horizontal position when lowered.
My improvement consists in the novel application and use of two.light rods
or bars secured together at their ends, the fabric of the blind passing between
these bars, so that the weight confines the loose blind to the lowest vertical
point or line, that is, at the elbow or joint of the hinged rods, where the rods
and blind are to be secured by connecting or attaching the said double rods to
the sliding ferrule or "runner" of the jointed rods, thus forming the "hood"
or "bonnet" of the blind at about a right angle with the vertical portion of
the blind, or that which is flat against the window, whereby the extra corner
pieces usually employed are dispensed with; or the same effect may be
obtained by the use of one rod fixed in the position of the double rods to
confine the blind at the required place.
In order that the Invention may be more fully understood and explained in
detail, I have hereunto attached a Sheet of Drawings made upon a scale of
about two inches to the foot, and having similar letters of reference marked
upon corresponding parts in all Figures.
Fig. 1 represents a front view of an exterior sun blind; Fig. 2 is an end
view of the same, shewing the confining bars and stretcher in the position
assumed when the blind is down; Fig. 3 is also an end view of the same,
shewing the position of the stretchers and bars when the blind is raised;
Fig. 4 is a detached and enlarged view of the confining bars and "runner," to
which they are attached.
In Figs. 1, 2, 3, a, a, is the case of the blind b, or roller upon which the
fabric of the blind is wound by means of a cord; c, c, are the stretchers to
which the lower end of the fabric is attached, and which are hinged to the
"runners" d, d, sliding upon the vertical rods e, e. When the blind is first
unwound to the full extent the confining rods i, i, are loose upon the fabric,
and draw the fabric into a vertical position against the window, and the
stretchers c, c, fall outwards at right angles; the confining rods i, i, are now
to be attached to the "runner," which may be effected by any convenient
means, such as by a pin upon the connecting plates k, k, entering a hole in the
runner," or vice versa, the "hood" being thus formed without the use of the
customary and hitherto necessary corner pieces, and may be raised or lowered
by means of the cord as required.

Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim forming the "hood" or "bonnet" of sun blinds by
means of one or more confining rods, either separate and loose from the fabric

page_text: or remaining upon the fabric, as shewn, for the purpose of producing an
external "hooded" sun blind without corner pieces, as herein-before described,
set forth, and fully illustrated in the Drawings attached.
In witness whereof, I, the said Joseph Lewtas, have hereunto set my
hand and seal, this Nineteenth day of October, in the year of our Lord!
One thousand eight hundred and sixty.
JOSEPH LEWTAS. (L.S.)
