CERTAIN, IMPROVEMENTS IN THE FITTINGS AND ACTION OF ROLLER BLINDS."
Year: 1875

page_text: LETTERS PATENT to Everard Blencowe, of Cheltenham, in the County
of Gloucester, for the Invention of "CERTAIN, IMPROVEMENTS IN THE
FITTINGS AND ACTION OF ROLLER BLINDS."
PROVISIONAL SPECIFICATION left by the said Everard Blencowe at
the Office of the Commissioners of Patents, with his Petition, on
the 22nd July 1875.
I, EVERARD BLENCOWE, of Cheltenham, in the County of Gloucester,
do hereby declare the nature of the said Invention for "CERTAIN IM-
PROVEMENTS IN THE FITTINGS AND ACTION OF ROLLER BLINDS," to be as
follows
The Invention is designed for the purpose of enabling roller blinds to
be raised or lowered with facility without the nse of the ordinary rack
and endless cord.

page_text: The improvements consist in forming a pulley on one end of the
blind, around which a cord or string is wound corresponding in length
to the length of blind. To one end of this string or cord a weight is
secured for the purpose of keeping the cord well wound round the pulley
without slackness, the said pulley being prevented turning too readily
by reason of a spring, which is caused to press against its flanges. This
spring prevents any movement of the blind so long as it is not being
pulled up by the pulley cord or down by the blind cord. The blind
when being pulled down winds the cord upon the pulley, the reverse
action or undwinding of which pulls up the blind.
"
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Everard
Blencowe in the Great Seal Patent Office on the 2nd February 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EVERARD
BLENCOWE, of Cheltenham, in the County of Gloucester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of July, in the
year of our, Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Ier heirs and suc-
cessors, give and grant unto me, the said Everard Blencowe, Ilcr
special licence, that I, the said Everard Blencowe, my executors, admı-
nistrators, and assigns, or such others as I, the said Everard Blencowe,
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,
usc, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"CERTAIN IMPROVEMENTS IN THE FITTINGS AND ACTION OF ROLLER BLINDS," upon
the condition (amongst others) that I, the said Everard Blencowe, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and scals, should particularly describe and
ascertain the nature of the said Invention, and in what manner tho
sanie was to be performed, and cause the same to be filed in the Great

page_text: eight hundred and seventy-six.
NOW KNOW YE, that I, the said Everard Blencowe, 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, reference being had to the annexed
Drawings, and to the figures and letters marked thereon, that is to
say
-
My said Invention relates to the construction and arrangement of
certain mechanism by means of which roller blinds for windows can be
raised or lowered with great facility without employing the ordinary
rack and endless cord
A pulley is placed on one end of the blind roller, around which pulley
a cord is wound, the length of the same corresponding to that of the
blind A weight is secured to one end of the cord for the purpose of
keeping the same well wound round the pulley without slackness, thic
said pulley being prevented from rotating too readily by means of a
spring, which is caused to press against its flanges, and which prevents
any movement of the blind so long as it is not being pulled up by the
pulley cord or down by the blind cord. Upon the blind being pulled
down the cord is wound upon the pulley, the reverse action or unwinding
of the cord causing the blind to 11se.
I will now proceed to refer to the annexed Drawings, from which the
nature of my said Invention will be more clearly understood.
Figure 1 represents the end of the blind roller with the mechanism
herein-before mentioned attached thereto B is the pulley at the end of
the rolle, and A. the spring which presses thereon in order to prevent
its rotating too readily; C is a pin, through a loop at the end of which
the weighted cord passes
Figure 2 shews the opposite end of the roller.
Having thus declared and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I would observe in
conclusion that what I consider novel and original, and therefore claim
as constituting the Invention secured to me by the said herein-before
in part recited Letters Patent are, the construction and arrangement of

page_text: fittings to be used in connection with roller blinds, substantially as
herein-before described and set forth.
In witness whereof, I, tho said Everard Blencowe, have hereunto
•
set my hand and scal, thus Twenty-seventh day of January, in
the year of our Lord One thousand eight hundred and seventy- &
