Year: 1803

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GAMBLE, of Leicester Square, in the County of Middlesex, Gentleman, send
greeting.
WHEREAS His most Excellent Majesty George the Third, of the United
Kingdom of Great Britain and Ireland King, Defender of the Faith, did, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, on or about the Twentieth day of April, 'in the forty-first
year of His reign, give and grant unto me, the said John Gamble, His
special licence, full-power, sole privilege and authority, that I, the said John
Gamble, my executors, administrators, and assigns, should and lawfully might,
during the term of years therein expressed, make, use, exércise, and vend
my Invention of a "Machine for Making Paper in single Sheets, without
Seam or Joinings, from one to twelve feet and upwards wide, and from one to
forty-five feet and upwards in length," within certain parts of the Dominions of
His said Majesty, and subject to certain provisoes, conditions, and limitations
therein expressed and contained: And whereas His said Majesty hath, by
His other Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, on or about the Seventh day of June, in the forty-third year
of His reign, granted unto me, the said John Gamble, his special licence, full
power, sole privilege, and authority, that I, the said John Gamble, my execu-
tors, administrators, and assigns, should and lawfully might, during the term' of
years therein expressed, make, use, exércise, and- vend my Invention of "CERTAIN

page_text: IMPROVEMENTS ON AND ADDITIONS TO A MACHINE FOR MAKING PAPER IN SINGLE
SHEETS, WITHOUT SEAM OR JOININGS, FROM ONE TO TWELVE FEET AND UPWARDS WIDE,
AND FROM ONE TO FORTY FEET AND UPWARDS IN LENGTH" (which said machine is
declared and expressed to be the same for which the said Letters Patent first
herein recited were obtained), within England, Wales, and the Town of
Berwick-upon-Tweed, and also in all His Majesty's Colonies and Plantations
abroad; in which said last recited Letters Patent there is contained a proviso
whereby it is declared that if I, the said John Gamble, should 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 the 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 advantages
whatsoever thereby granted, should utterly cease, determine, and become void.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Gamble, do hereby declare that my said Invention of certain improve-
ments on and additions to the said machine is described in manner following,
that is to say-
Instead of the fly marked p in the Drawing marked No. 3, belonging to
the Specification of the said machine for which the said first recited Letters
Patent were granted (to which Specification and the Drawings forming part
thereof I do here and in the subsequent part of this present Writing refer),
I do substitute two wheels or flys of the same kind, one revolving in the
material or pulp to bring it up, and the other (which is smaller) revolving
above the surface of the pulp, and serving to receive it from the first, and
deliver it through the cap, as represented in the said Drawing.
Secondly, instead of producing the shake or side agitation by the outside
action of a wheel I, No. 2, I produce the same by causing the pin to move in
a groove or cavity, cut waving in the face of a wheel, or between two surfaces
which shall confine the said pin both ways, and render it impossible that any
jerk should be produced by the pin being driven off during the quick motion
of the machine.
Thirdly, instead of limiting the breadth of the piece by the facing or edge of
eelskin attached to the edge of the circulating piece a No. 2, and suffering the
superfluous pulp to run over the sides of the said circulating piece, I do limit
the said breadth by two gauges, one on each side, consisting of pieces of
wood having their lower edges nearly in contact and proceeding from the
commencement of the said piece to the extent of about two feet more or less
longitudinally, and I make the space between each gange and the circulating

page_text: piece sufficiently tight or close by means of an endless strap or leather, or
other suitable material, which is moved round pullies at the end of the gauge
(by the well known methods of mechanical connection) so as to pass with a
velocity equal to that of the circulating piece itself. And I do fix, at the com-
mencement of and nearly in contact with the said circulating piece, in a cross
direction between gauge and gauge, a ruler of copper, of such a thickness as to
allow the superfluous pulp to run back into the vat over the said ruler and
the space beneath the same, and the circulating piece is made sufficiently
close by a small flap or appendage from the ruler made of oiled silk or other
flexible stuff.
Fourthly, instead of the hooks and rulers h, h, No. 2, for confining and
extending the circulating piece a, I affix a number of buttons to the edges of
the said piece, which pass along the outer surfaces of two copper rulers on
each side, extending from the first stretching roller e, No. 2, to the pressing
rollers at ff, while the shanks or tails of the said buttons are confined in the
groove or space between the said rulers. And I.fix on each side, beneath the
said circulating piece, near the said first stretching roller, two other short rulers
for receiving and directing the buttons fairly to the said roller, in order to the.
completion of which the extremities of the said last-mentioned rulers are
curved or bended inwards.
Fifthly, instead of the wooden knife 4, in Figure 5 of the Drawings before
referred to, I substitute a wire or string.
Sixthly and lastly, when the circulating piece is of considerable dimensions,
I support and prevent it from yielding downwards by one or more rollers
revolving along with it.
In witness whereof, I, the said John Gamble, have hereunto set my
hand and seal, the Fifth day of December, in the forty-fourth year of
the reign of our Sovereign Lord George the Third, by the grace of
God, of the United Kingdom of Great Britain and Ireland King,
Defender of the Faith, and in the year of our Lord One thousand
eight hundred and three.

page_text: AND. BE IT REMEMBERED, that on the same Fifth day of December,
in the year above mentioned, the aforesaid John Gamble came before, our,
Lord the King in His Chancery, and acknowledged the Specification aforesaid,
and all and every thing' therein contained, in form above written. And also
the Specification aforesaid was stamped according to the tenor of the Statute
in that case made and provided.
