Year: 1811

page_text: TO ALL, TO WHOM THESE PRESENTS SHALL COME, I, JAMES'
PARSONS, of Wellington, in the County of Somerset, Builder, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
Ilis Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at. Westminster, the Twenty-first day of May,.
in the fifty-first year of His reign, give and grant unto me, the said James
Parsons, my exors, adñiors, and assigns, His especial licence, full power, sole
privilege and authority, that I, the said James Parsons, my exors, adiñiors, and
assigns, during the term of years therein mentioned, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "HINGES AND PULLIES FOR DOORS AND
WINDOWS;" in which said Letters Patent there is contained a proviso, that
if I, the said James Parsons, 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 enrolled in His Majesty's High Court of Chancery within two calendar
months next and immediately after the date of the said recited Letters Patent,
that then the said Letters Patent, and all liberties, advantages whatsoever
thereby granted, shall utterly cease, determine, and become void, as in and by
the said Letters Patent, relation being thereunto had, may more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Parsons, do hereby declare that my said Invention of binges and

page_text: pullies for doors and windows are particularly described and ascertained in
and by the Drawings and references thereto, and further description thereof
hereunto annexed:-
A, A, represents the hinge in two parts; B, the barrel of the hinge which
contains the spring; C, the collar, an inch from the bottom, for the spring to
bear on; D represents the spring c, 2 collars, as it stands in the barrel, with
the pin through and caps at the ends; E, E, roller and pin at the bottom of
the hinge to draw down the door, instead of a roller on the top, when the door
is fastening; F is a projection to form a rising hinge; G is the hinge put
together for use; H, the roler for the top of the door to press it down; I, the
plate for the roler to work against..
My method for constructing pullies for doors and windows upon a new
principle is as follows:-I take in general a spring, according to the strength
I want, and confine it in a box, in the same way that the spring in a table
clock is confined; by this I gain the power requisite to rise the sash or draw
the door; or else I construct my spring so that I need not the box, my Invention
being yo applying the power of a spring for the rising of a sash, or drawing
of a door, instead of a weight, as is the present mode. I do not specify for
any new spring, or new way of giving action to the spring; but my Invention is
simply, and which I consider new, the application of a spring or springs to raise
the sash or draw a door, instead of weights..
In witness whereof, I, the said James Parsons, have hereunto set my hand
and seal, this Sixteenth day of July, in the year of our Lord One
thousand sight hundred and loven
