page_text: LETTERS PATENT to John Tatham and David Cheetham, of Roch-
dale, in the County of Lancaster. Machine Makers, for the Inven-
tion of "IMPROVEMENTS IN ROLLERS OR BOSSES USED FOR DRAWING
OR CONVEYING TEXTILE MATERIALS AND D
Scaled the 1st April 1858, and dated the 7th October 185
PROVISIONAL SPECIFICATION left by the said John Tatham and
David Cheetham at the Office of the Commissioners of Patents,
with their Petition, on the 7th October 1852.
We, JOHN TATHAM and DAVID CHEETHAM, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN ROLLERS OR BOSSES
USED FOR DRAWING OR CONVEYING TEXTILE MATERIALS AND FABRICS". to le
as follows:-
Our improvements consist, firstly, in the adaptation of cork to the
rollers or bosses of machines used in the manufacture of textile sub-
stances, and also in various treatments of textile fabrics, as, for instance,
in the drawing frame." "throstle," "doubling frame," &c. &c., as
applied to unwoven materials; and in various machines for rolling or

page_text: squeezing woven fabrics. The rollers may be constructed by any of
the usual methods, and the cork then applied in one or more layers;
as a solid block, in segments, or in any other manner; after which
a covering of flannel or other cloth, gutta percha, leather, varnish.
Secondly,
or any other suitable substance, may be applied if desired.
our Invention consists in constructing rollers as aforesaid by the
application of gutta percha covered with cloth, leather, varnish, or
other suitable substance; the gutta percha may be applied in portions,
or in one thickness, and should be rendered more elastic than in its
ordinary state by any of the known methods.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Tatham and David Cheetham in the Great
Seal Patent Office, on the 7th April 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME. we,
JOHN TATHAM and DAVID CHEETHAM, of Rochdale, in the County of
Lancaster, Machine Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of October, in the year
of our Lord One thousand eight hundred and fifty-two, in the six-
teenth year of 1ler reign, did, for Herself, Tler heirs and successors,
give and grant unto us, the said John Tatham and David Cheetham,
Her especial license that we, the said John Tathan and David
Cheetham, our executors, administrators, and assigns, or such others
as we, the said John Tatham and David Cheetham, our executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man. an Invention for "IMPROVEMENTS
IN ROLLERS OR BOSSES USED FOR DRAWING OR CONVEYING TEXTILE
MATERIALS AND FABRICS," upon the condition (amongst others) that
we, the said John Tathan and David Cheetham. by an instrument in

page_text: writing under our hand and seal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Tathan and David
Cheethain, do hereby declare the nature of our Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement (that is to say):
Our improvements consist, firstly, in the adaptation of cork to the
rollers or bosses of machines used in the manufacture of textile sub-
stances, and also in various treatments of textile fabrics. The rollers
may be constructed by any of the usual methods, and the cork then
applied in one or more layers, in segments, or in any other manner.
after which a covering of flannel or other cloth, gutta percha, leather,
varnish, or any other suitable substance, may be applied, if desired.
Secondly, our Invention consists in constructing the rollers used in
preparing and spinning textile materials by the application of gutta
percha, covered with cloth, leather, varnish, or other suitable substance;
the gutta percha may be applied in portions, or in one thickness.
The method which we prefer in reference to the first part of our In-
vention, and as applied to preparing and spinning machinery is, to coat
the metal rollers with a thin film of fine sawdust. applied with some
adhesive substance, after which a layer of sheet cork is wound upon the
surface, and caused to adhere by shel-lac varnish; the leather or other
outward covering (if such be desired) is then applied by drawing on, or
other ordinary means. In reference to textile fabrics, this part of our
Invention may be applied to rollers used for calendering, to those
employed in printing machines, or to others where elasticity is required.
In such cases we prefer applying the cork in discs provided with central
orifices, which being strung side by side upon a spindle are compressed
together, and secured by nuts or other means.
The gutta percha to be applied according to the second part of our
Invention may be drawn on to the metal or other rollers as a tube, or
lapped thereon in a similar manner to that described in reference to

page_text: the cork, and subsequently covered by leather, cloth, varnish, or other
substance suitable to the nature of the material to be operated upon.
The degree of elasticity in the rollers may be varied, as required, by
thick or thinner applications of cork, or by rendering the gutta percha
more or less elastic by any of the known methods; and, if desired, our
two improvements may be combined by covering a roller or boss to
which gutta percha is applied with a layer or layers of cork.
Having thus described the nature of our said Invention, and the
nanner of carrying the same into effect, we desire it to be understood
that we claim as secured to us,-
Firstly, the adaptation of cork to rollers or bosses used for drawing
or conveying textile materials or fabrics.
Secondly, as applied to machinery for preparing and spinning textile
materials; the employment of gutta percha as a covering or partial
covering for rollers or bosses; such gutta percha being provided with
an outward coating of leather, cloth, varnish, or other suitable
substance.
In witness whereof, we. the said John Tatham and David Cheet-
ham, have hereunto set our hands and seals, this Sixth day of
April, in the year of our Lord One thousand eight hundred and
throo
JOHN TATHAM.
