Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, TноMAS
BURY, of Salford, in the County of Lancaster, Silk, Worsted, and Piece
Dyer and Finisher, and NATHAN RAMSDEN, of the same place, Callenderman
and Finisher, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Thirty-first day of January, in the thirteenth year of Her reign, and
in the year of our Lord One thousand eight hundred and fifty, did give. and
grant unto us, the said Thomas Bury and Nathan Ramsden, our exors,
adiñors, and assigns, Her especial licence, full power, sole privilege and
authority, that we, the said Thomas Bury and Nathan Ramsden, our exors,
admors, and assigns, and such others as we, the said Thomas Bury and
Nathan Ramsden, our exors, adñiors, and assigns, should at any time agree
with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise,
and vend, within that part of Great Britain and Ireland called England,
and Her Dominion of Wales, and the Town of Berwick-upon-Tweed, our
Invention of "CERTAIN IMPROVEMENTS IN MACHINES FOR GLAZING, EMBOSSING,
AND FINISHING WOVEN FABRICS AND PAPER;" in which said Letters Patent is
contained a proviso that we, the said Thomas Bury and Nathan Ramsden,

page_text: or one of us, shall cause a particular description of the nature of our said
Invention, and in what manner the same is to be performed, by an instru-
ment in writing under the hand and seal of one or both of us, to be
enrolled in Her Majesty's High Court of Chancery within two calendar
months next and immediately after the date of the said in part recited
Letters Patent, as, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Thomas Bury and Nathan Ramsden, do hereby declare that the nature of
our said Invention, and the manner in which the same is to be performed,
is particularly described and ascertained in and by this present instrument
in writing, reference being had to the Drawings hereto annexed (that is
to say)-
Our said Invention or improvements apply particularly to machines for
glazing, embossing, and finishing calicos, muslins, woven or printed fabrics, and
paper. The chief feature or novelty of our said Invention consists in the
arrangement and application of two or more friction bowls, rollers, or cylin-
ders, made of iron, or any metal or material suitable for the purpose, acting
in conjunction with one principal bowl or roller made of paper or any other
suitable material, instead of the arrangement of one friction bowl, roller, or
cylinder, as used in the ordinary machines now in use for the aforesaid or
similar purposes. This application or arrangement of two or more friction
bowls, rollers, or cylinders, in conjunction with one principal bowl or roller, to
machines for glazing, embossing, and finishing woven or printed and other
fabrics and paper, commonly called calender machines, is for the purpose of
economising the power and producing more work in the same space of time,
whereby a very considerable saving of labor, time, and expense is effected.
It will be seen that this machine is equally applicable to the aforesaid purposes
if inverted, as shewn in Figures 4 and 5 of the Drawings hereunto annexed,
a greater amount of pressure is thus gained by forcing the principal or paper
bowl on and between the two friction bowls, instead of the two friction bowls
being forced upon the principal or paper bowl; and this arrangement also
renders practicable the working of two pieces of cloth, fabric, or paper, with
the same facility as one.
Having described the nature of our said Invention, we will proceed to shew
the manner of carrying the same into practical effect, which will be fully
explained by reference to the Drawings hereunto annexed, and the following
description thereof :-
Fig. 1 represents an end elevation, shewing the principal or paper bowl or

page_text: roller in connection with the machine; Fig. 2, a longitudinal elevation of the
machine, with the gearing or driving motion attached; Fig. 3, elevation of
gearing or driving motion; Fig. 4, a cross section of the same machine
inverted, by which improvement two pieces of cloth, fabric, or paper, can be
glazed, embossed, or finished at the same time; Fig. 5, an end elevation of the
same machine inverted. In all these Figures similar letters of reference are
marked upon corresponding parts. a is the principal or paper bowl or roller;
b, b, are the two friction bowls, rollers, or cylinders, made of iron or any other
suitable metal or material heated in the usual manner; c, c, is the cloth,'
fabric, or paper, passing between the said bowls, rollers, or cylinders b, b,
and a, and represented by red lines; d is a bowl or roller made of iron or
any other suitable metal, called the drag bowl or roller, which by pressure
holds back the principal or paper bowl, whereby the bowls b, b, produce the
glaze or finish on the cloth, fabric, or paper, in consequence of the friction; '
or, to emboss or finish without the friction, e, e, are square threaded screws,
for the purpose of forcing the bowls against each other, whereby the pressure
is obtained; ff, are wheels by which the first motion or moving power is
obtained; 9; 9, are wheels which give motion to the two friction bowls or
rollers h, h, which drive the shaft i; this shaft has a spur pinion j working
in gear with the wheel k on the end of drag roller d, by which improvement
in the arrangement of the gearing or drag motion a greater glaze or finish can
be given to the fabric or paper.
Having described the nature of our Invention, and the mode or arrange-
ment for carrying out or effecting the same, we would have it understood that
we do not confine ourselves to the details herein described, so long as the
peculiar character or novelty of our Invention is retained; neither do we
make any claim as to the details and arrangements of the various parts of the
said machines herein referred to, save only those parts or portions as herein
described as of or belonging to our Invention. But what we claim is,
the application and arrangement of two or more friction bowls, rollers, or
cylinders, in conjunction with one principal or paper bowl, and the mode or
modes of arrangement for working one or two pieces of cloth, fabric, or paper
with two or more friction bowls or rollers at the same time.
In witness whereof, we, the said Thomas Bury and Nathan Ramsden,
have hereunto set our hands and seals, this Twenty-seventh day of
March, in the year of our Lord One thousand eight hundred and fifty.
THOMAS (L.S.) BUKI.
NATHAN (L.s.) RAMSDEN.

page_text: AND BE IT REMEMBERED, that on the Twenty-seventh day of March,
in the year of our Lord 1850, the. aforesaid Thomas Bury and Nathan
Ramsden came before our said Lady the Queen in Her Chancery, and
acknowledged the Specification aforesaid, and all and every thing therein
contained and specified, in form above written. And also the Specification 5
aforesaid was stamped according to the tenor of the Statute made for that
purpose.
