ROBERTS, of Brownlow. Street, Drury Eane, in the County of Middlesex, Blind
Maker; send greeting...
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal, of the United Kingdom of Great
Britain and Ireland, bearing date rat Westminster, the Seventh day of April,
in the fifty-fourth year. of His reign, give. and grant unto me, the said
Joseph Roberts, my exors; adñiors, and assigns, His especial licence, full power,
sole priviledge and authority, that I; the said Joseph Roberts, my exors, adiñors,
and assigns; should: and: lawfully might; during the term of years, therein
mentioned; make; use exercise,..and vend, within England,. Wales, and the
Town of Berwick-upon-Tweed, my: Invention of "AN APPARATUS INTENDED TO
'BE USED FOR MAP. ROLLERS AND CARRIAGE BLINDS, AND OTHER SIMILAR OBJECTS;"
in which said Letters Patent there is contained a proviso that if I, the said
Josepli Roberts, shall not particularly describe and ascertain the nature 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 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 whatso-

page_text: ever thereby granted, shall utterly, cease, determine, and become void, as
in and by the same (relation being thereunto had) may more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Roberts, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the Drawing hereunto annexed, and the following
description thereof, that is to say:
What I claim as my Invention is, drawing up the cloath for a roller blind
by a spring and other apparatus in a bracket intended to be fixed at one or
each end of the roller, instead of having a tin barrel and worm spring in it. I
here describe the plan by Fig. 1, 2, and 3. Fig. 1 shews an empty box or
.bracket. Fig. 2 is the apparatus in it. Fig. 3 the works covered with a
plate, Letter H, all except part of the pinion D, which is intended to go into
the end of the roller L. I next shew it disected. A a ketch; B a spring
which keeps the ketch down to rotchet wheel C (these are not my Invention,
but used for other blinds). Da pinion cog wheel; E a spring intended to go
in box F. and E in F shews the spring in the box before put into Fig. 1 (the
spring may be fixed in the outside box, but this is preferred); G, a cog wheel
which drives pinion D, and pinion D drives wheel G, when the blind is
drawn down, so they act alternately; K a bracket to support the other end of
the roller; L shews one end of the roller; D, in Fig. 3, is part of the pinion
that goes into the end of the roller; the hole a in spring E goes on hole a in
box F, and the hole 6 in spring E goes on hook bin wheel G.
are screw holes to receive screws to screw brackets on au angular box.
Fig. 4 shews a box for a coach blind. The boxes may be made various sizes
and shapes, but the work inside is the same, only varying in size, agreeable to
-suit the length and weight of cloath they have to draw up. Fig. 5 shews the
blind compleat. By drawing the cloath down it turns round the pinion D,
which turns round wheel G, and charges the spring E; the ketch A catches
in rotchet wheel G, and keeps the cloath to any part of the window as its drawn
down, and by releasing the ketch by line M in Fig. 5, the spring operates on
wheel G, and instantly turns round pinion D, which draws the blind up to any
part required. As soon as you cease to pull, the blind is prevented from going
up higher by ketch A.
