page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of October, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Parker, Her special licence that I, the said Joseph
Parker, my executors, administrators, and assigns, or such others as I, the
said Joseph Parker, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "AN IMPROVED METHOD
OF FITTING AND WORKING VENETIAN AND OTHER SIMILAR BLINDS USED AS VENTI-
LATORS OR SCREENS, OR BOTH," upon the condition (amongst others) that I, the
said Joseph Parker, 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 Joseph Parker, 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 fol-
lowing statement thereof, reference being had to the Drawings hereunto
annexed, that is to say :-
My Invention consists in fitting the plates or louvres composing the blinds
in pairs or double sets in a frame, which is acted upon from the side or other
convenient part of the blind, and by the moving of which both sets of plates
or louvres are wholly or partially opened or closed to the extent desired.
In the Drawings hereunto annexed I have illustrated the best method with
which I am acquainted of carrying my Invention into effect.
Figure 1 is a front view of an improved blind constructed according to my
Invention, showing the plates or louvres closed, and Figure 2 is a horizontal
section of the same, taken through the middle; Figure 3 is a front view of
the blind, shewing the plates or louvres open, and Figure 4 is a horizontal
section of the same, taken similarly to Figure 2; Figure 5 is a horizontal
section through the line x, x, of Figure 1, shewing the parts by which the
blind is opened and closed. The plates or louvres A, A, are respectively con-
nected by spindles a, a, with the levers B, B, which again are connected by
pins to side levers C, C. These levers C, C, are jointed to rods D, D, to which

page_text: motion may be given by the sliding stud E. By moving the stud to the right
the whole of the louvres may be opened, either to a small extent to admit air
freely but prevent persons looking through them, or to a
through them, or to a larger extent to
permit them to do so.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I do not confine myself to
precisely the arrangement illustrated; but what I do claim is, fitting the plates
or louvres composing the blinds in pairs or double sets in a frame, which is
acted upon from the side or other convenient part of the blind, and by the
moving of which both sets of plates or louvres are wholly or partially opened
or closed, as herein-before described, and illustrated in the Drawings hereunto
annexed.
In witness whereof, I the said Joseph Parker, have hereunto set my
hand and seal, this Tenth day of April, One thousand eight hundred
and fifty-eight.
JOSEPH PARKER. (L.S.)
