IMPROVEMENTS IN THE CONSTRUCTION OF BLIND ROLLERS
Year: 1875

page_text: LETTERS PATENT to William Henry Parker, Mechanical Draughts-
man, and John Elliott, Railway Inspector, both of Bedford, in the
County of Bedford, for the Invention of “IMPROVEMENTS IN THE
CONSTRUCTION OF BLIND ROLLERS."
Sealed the 4th January 1876, and dated the 10th July 1875.
PROVISIONAL SPECIFICATION left by the said William Henry Parker
and John Elliott at the Office the Commissioners of Patents, with
their Petition, on the 10th July 1875.
We, WILLIAM HENRY PARKER, Mechanical Draughtsman, and JOHN
ELLIOTT, Railway Inspector, both of Bedford, in the County of Bedford,
do hereby declare the nature of the said Invention for “IMPROVEMENTS
IN THE CONSTRUCTION OF BLIND ROLLERS," to be as follows:-
The object of the present Invention is to construct rollers for window
blinds in such a manner that the blind may be more effectually secured
thereto than is the case in blind rollers of the usual construction, and at
the same time to admit of their being readily removed for the purpose of
being washed,

page_text: To effect this object we form the roller with a bore or perforation
running from one end of the roller to the other, and into this bore or
perforation we cut a narrow slit extending from the outside of the roller,
and running from end to end.
The top of the blind is hemmed, and into the hem we insert a rod of i
wood or metal; the rod with the blind attached is then passed into the
bore or tube in the roller, and the blind depending through the slit will
thus be firmly and effectually secured.
In order to remove the blind for the purpose of washing or for
attaching a new one it will only be necessary to draw out the rod and 1
blind from the bore in the roller, when the blind may be readily slipped
off the rod.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Henry Parker and John Elliott in the
Great Seal Patent Office on the 10th January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY PARKER, Mechanical Draughtsman, and JOHN ELLIOTT, Railway
Inspector, both of Bedford, in the County of Bedford, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth 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, Her heirs and successors,
give and grant unto us, the said William Henry Parker and John
Elliott, Her special licence that we, the said William Henry Parker,
and John Elliott, our executors, administrators, and assigns, or such
others as we, the said William Henry Parker and John Elliott, our
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, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IN-
PROVEMENTS IN THE CONSTRUCTION OF BLIND ROLLERS," upon the condition
(amongst others) that we, the said William Henry Parker and John
Elliott, our executors or administrators, by an instrument in writing

page_text: ticularly 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 we, the said William Henry Parker and
John Elliott, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of the present Invention is to construct rollers for window
blinds in such a manner that the blind may be more effectually secured
thereto than is the case with blind rollers of the usual construction, and
at the same time to admit of their being more readily removed for the
purpose of being washed or renewed.
In the accompanying Drawing we have shown various views of a
blind roller constructed according to our Invention, Fig. 1 being a front
view of a roller with the blind attached thereto; Fig. 2, a transverse
vertical section of the same; and Fig. 3, a longitudinal vertical section
of the same through the line 1, 2, of Fig. 2, the blind being
removed.
a, a, is the blind roller, which is formed with a bore or perforation b, b,
running from end to end, and with a longitudinal slit c, c, extending
from the outside at the roller into the bore or perforation b, b. This
perforation b, b, and slit c, c, may best be formed by making the roller
in two halves, the bore and slit being made half in one section and half
in the other. The two sections are then secured together, as indicated by
the line 1, 2, in Fig. 2, but it may be formed in any other convenient
manner. The top of the blind fis bemmed, and into the hem is inserted
a rod g, g, of wood or metal, and the rod with the blind attached is
then passed into the bore or perforation b, b, the blind depending through
the slit c, c, will thus be firmly secured to the roller. The boro band
slit o may either be continued through the flange / of the roller, or the
flange or pulley i may be made to screw off and on, as shewn at i,
Fig. 1. The flange or the pulley may thus be removed for the purposes
of withdrawing or inserting the rod g, and then replaced.

page_text: The foregoing description applics: moro particularly to rollers formed
of wood, but it is obvious that they may be formed of metal or of any
other suitable material. They may be, for instance, formed of a simple
tubo of metal with an open joint, such as that shewn in the sectional
view, Fig. 4, or they may be made of a double tube, as shewn at
Fig. 5.
In order to remove the blind from the roller for the purpose of washing
or renewal it will only be necessary to draw out the rod g with the blind
attached; the latter may then be slipped off the rod, and be replaced by
a fresh onc.
Having now set forth my Invention of improvements in the con-
struction of blind rollers, and having explained the manner of carrying
the same into effect, I wish it to be understood that under the above in
part recited Letters Patent we claim, the construction of blind rollers,
in the manner and for the purpose herein set forth.
In witness whereof, we, the said William Henry Parker and
John Elliott, have hereunto set our hands and seals, this Eighth
day of January, in the year of our Lord One thousand eight
hundred and seventy-six.
