Year: 1812

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LEGER
DIDOT, of Prospect Place, Edgware Road, in the County of Middlesex, Gen-
tleman, 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 at. Westminster, the Second day of June,
in the fifty-second year of His reign, give and grant unto me, the said
Leger Didot, my exors, adññiors, and assigns, His especial licence, full power,
sole privilege and authority, that I, the said Leger Didot, my exors, admors,
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, the Invention communicated to me by a
certain Foreigner residing abroad, of a "CERTAIN IMPROVEMENT IN MOULDS FOR
MAKING PAPER;" in which said Letters Patent there is contained a proviso
that if I, the said Leger Didot, shall not particulary describe and ascertain
the nature of the 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 six calen-
dar 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, 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
Leger Didot, do hereby declare that the nature of the said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained as follows, that is to say :-

page_text: The said improvement is made in the moulds for making the paper called
laid paper; and instead of fixing, attaching, sewing, or otherwise fashioning my
wires of and in the said moulds unto or upon the bars or immediate supports,
as is commonly done and practiced, whereby, or in consequence of which, the
paper is disposed to become heavy on the bar, or thicker near the bar than
elsewhere, I do.fix, attach, sew, or otherwise-fasten,-unto or- upon the said
bars or immediate supports, a set of wires farther asunder from each other, or
more open than would be required to make paper; and I do place, and duly
secure upon the said last-mentioned set of wires, two or more strait wires,
intermediate between, and parallel to each of the said bars or supports, and
serving as the direct supports to another upper set of wires, fabricated and put
together in the common way,-upon-which the paper is to be received, formed,
and made; and I do place the last-mentioned set of wires thereon, and care-
fully fasten the same by sewing to the more open wires beneath, in such
manner with regard to the chain or sewed lines or sewing, the said external or
upper wires, as shall be considered or found to be best adapted for the perfect
and equable supporting of the said upper wires, and the due and regular flow
or draining off of the water, and uniform disposal of the paper stuff or pulp
upon the said mould, instead of any impediment to the said effects being
suffered or allowed to take place from the interposition or immediate contact
of the said bars with regard to the said upper wires, or the chain sewed lines,
or sewing of the same.
In witness whereof, I, the said Leger Didot, have hereunto set my
'hand and seal, this Fourteenth day of October, in the year of our
Lord One thousand eight hundred and twelve.
L. DIDOT. (L.S.)
AND BE. IT REMEMBERED, that on the Fourteenth day of October. in
