page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BAYLEY, of Birmingham, in the County of Warwick, Brassfounder, send
greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fifteenth day of
January, in the fiftieth year of His reign, did give and grant unto me, the
said Thomas Bayley, my exors, admors, and assigns, His especial licence, full
power, sole priviledge and authority, that I, tho said Thomas Bayley, my exors,
adñiors, and assigns, during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within that part of the United
Kingdom of Great Britain and Ireland called England, Wales, and the Town
of Berwick-upon-Tweed, my." NEW INVENTED SLIDING PULLIES FOR WINDOW
BLINDS AND OTHER PURPOSES," and that I, the said Thomas Bayley, my exors,
adñiors, and assigns, should and lawfully might have and enjoy the whole
profit, benefit, commodity, and advantage from time to time coming, growing,
accruing, and arising by reason of the said Invention, for and during the term
of years
therein mentioned, to have, hold, exercise, and enjoy the said licence,
powers, privileges, and advantages therein-before granted, or mentioned to be
granted, unto me, the said Thomas Bayley, my exors, adiñors, and assigns,
for and during and unto the full end and term of fourteen years from
the date of the said Presents next and immediately ensuing, and full to
be complete and ended according to the Statute in such case made and
provided; in which said Letters Patent is contained a proviso that if I, the

page_text: said Thomas Bayley, should not particularly describe and ascertain the naturo
of my said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, and cause the same to be
inrolled in His said Majesty's High Court of Chancery within two calendar
months next and immediately after the date of the said Letters Patent, that!
then the said Letters Patent, and all liberties and advantages whatsoever
thereby granted, should utterly cease, determine, and become void, anything
therein-before contained to the contrary thereof in anywise notwithstanding,
as in and by the said Letters Patent, relation being thereunto had, may more
fully and at large appear.
NOW KNOW YE, that I, the said Thomas Bayley, in compliance with the
said proviso, do hereby describe and ascertain the nature of my said Invention,
and that my first and principal improvement is the application of a screw
(instead of a rack and spring) to the moveable part or slide in my sliding
pullies for window blinds, and all other purposes for which they may be used,
by the action or revolving of which the slide may be moved up or down or be
kept firmly fixed at any height within the frame or caso; and I hereby declare
that the plan or description thereof drawn in the margin of these Presents is
composed of the following particulars, that is to say:-
No. 1, a frame or case, made hollow to receive slide No. 2, and which
frame or case is to be affixed to the window frame or other situation where it
may be applied.
No. 2, a slide, to fall into the hollow part of No. 1, and pierced at each end
for the points of escutcheon or collar No. 6 to pass through, and also pierced
in the center for screw No. 3 to pass through, and which slide with a small
cog is meant to run from A to A.
No. 3, a screw, with or without a nut, brazal or soldered firmly on or near
its center, to pass through the hole drilled in the center of slide No. 2, and
which screw I make either to act at one of the extreme points B, B, or at
or near the center, where the action is concealed by the escutcheon or collar,
and I make the screws to act either by a regular or inverted motion, and to
repel or attract the slide or escutcheon, as I wish it.
No. 4, a nut, soldered on the end of No. 3 at C, with a small cog on one
part of it to prevent the screw, on releasing the slide, escutcheon, or collar,
from revolving too far back.
.
No. 5, a nut, to fix at or near the center of screw No. 3, and upon which
center nut I sometimes turn a screw, which acts within another screw, which
I term the female, and which female screw is concealed within the escutcheon,
as referred to in Drawing No. 6, Figure 4.

page_text: No. 6, Figure 1, 2, 3, & 4, an escutcheon or collar, with or without a
shoulder, to fasten by its joints on No. 2, and to bear or rest on frame or
case No. 1.
No. 7, a pulley or bowl, round which a cord or line is to run to draw up
the blind or curtain, and through the center of which a hole is drilled to make
it to perform its revolutions round the spindle part of screw No. 3.
No. 8, a knob, nut, or thumb-piece, which fixes on the end of screw No. 8
at D, and which, by turning, presses the nut brazed on No. 3 against the
escutcheon, slide, or frame, and by that means prevents the slide from moving
up and down the frame or case; and I sometimes make my sliding pullies
without an escutcheon, in which case the nut brazed on the centre of No. 3
presses against the frame or case; and I make the several parts of my said
Invention of brass, iron, tin, copper, or any other metal or any composition of
metals.
In witness whereof, I, the said Thomas Bayley, have hereunto set my
band and seal, the Fifth day of March, in the year of our Lord One
thousand eight hundred and ten.
