CERTAIN IMPROVEMENTS ON MACHINERY USED FOR CUTTING PAPER, WHICH I INTEND TO DENOMINATE BAISLER'S PATENT PAPER PLOUGH
Year: 1817

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCIS
BAISLER, of Oxford Street, in the County of Middlesex, Stationer, 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 Twenty-eighth
day of November, in the fifty-eighth year of His reign, give and grant unto
me, the said Francis Baisler, my exors, adñiors, and assigns, His especial
licence, full power, sole privilege and authority, that I, the said Francis
Baisler, my exors, adiñors, and assigns, should and lawfully might, during
the term of years therein expressed, make, use, exercise, and vend my said
Invention within that part of the United Kingdom of Great Britain
and Ireland called England, the Dominion of Wales, and Town of Ber-
wick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS ON MACHINERY
USED FOR CUTTING PAPER, WHICH I INTEND TO DENOMINATE BAISLER'S PATENT
PAPER PLOUGH;"" in which said Letters Patent there is contained a proviso
that if I, the said Francis Baisler, 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 six calendar months next and immediately after the date of the said
Letters Patent, that then the said Letters Patent, and all liberties and

page_text: 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 THEREFORE, that in compliance with the said
proviso, I, the said Francis Baisler, 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 following description
thereof (that is to say):-
The Invention consists in the more expeditiously cutting paper or other
substances, and for more certainly cutting parallel and true to any given size,
for the use of stationers and others, and is formed by an oblong frame of
wood, iron, or other material, with a middle or moveable piece which moves on
a slide at each end, parallel with the two other sides of the frame. For
the pressing power I make use of a screw or screws, a lever or levers,
hydraulic or other force. The screws work in the moveable piece, passing
thro' and bearing against one side of the frame. On the end of each screw I
fix a wheel or pulley, and one in the centre; and on the centre one is fixed a
second wheel or pulley, a handle lever, or other means of giving motion, which
moves the screws equally, and consequently gives the press a parallel move-
ment and even pressure, and renders the operation quicker than moving the
screws singly. On the opposite side of the frame is a slide that moves on a
cylinder or between two parallel guides by means of a screw, lever, rack and
pinion, or other force. On the slide is placed one or more cutters, which
may be set to any angle so as to extend the full thickness of the paper or other
substance intended to be cut. And by the movement of the screw or other
force above mentioned the cutter or cutters pass from one end to the other,
performing the operation at once and with more facility than the common
way, and perfectly parallel, which can seldom be obtained by the usual method.
The press may be made either perpendicular or horizontal. To either method
I attach a sliding board, which moves upon two parallel slides by means of
rack and pinion, screw, or other means of giving motion, and regulates the
paper or other substance to be cut to any size with the utmost precision.
This very useful part of my Invention I can apply advantageously to the
common press or plongh.
In witness whereof, I, the said Francis Baisler, have hereunto set my
hand and seal, this Twenty-fifth day of May, in the year of our Lord
One thousand eight hundred and eighteen.
FRANCIS (L.S.) BAISLER.
