Year: 1868

page_text: LETTERS PATENT to John Worth, of Rochdale, in the County of
Lancaster, Card Maker, and Abraham Barker, of the same Place,
Plumber, for the Invention of "IMPROVEMENTS IN COVERING ROLLERS
AND CLEARERS USED IN MACHINERY FOR PREPARING AND SPINNING FIBROUS
MATERIALS."
PROVISIONAL SPECIFICATION left by the said John Worth and
Abraham Barker at the Office of the Commissioners of Patents, with
their Petition, on the 4th June 1868.
We, JOHN WORTH, of Rochdale, in the County of Lancaster, Card
Maker, and ABRAHAM BARKER, of the same Place, Plumber, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN COVERING

page_text: ROLLERS AND CLEARERS USED IN MACHINERY FOR PREPARING AND SPINNING
FIBROUS MATERIALS," to be as follows:-
Our Invention consists, firstly, in the use of woollen cloth combined
with linen or cotton cloth as a substratum to which the usual leather
covering is subsequently applied. The woollen fabric may be felted
or woven, but we prefer the former, and it may to a certain extent be
mixed with other fibrous materials, as is now practised; upon this we
cement linen or cotton cloth, and the roller or clearer having been
covered therewith the leather is applied in the usual manner.
Secondly. We dispense with the above-mentioned linen or cotton 1
cloth, and use the felted cloth only.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Worth and Abraham Barker in the Great
Seal Patent Office on the 4th December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, Jonn
WORTH, of Rochdale, in the County of Lancaster, Card Maker, and
ABRAHAM BARKER, of the same Place, Plumber, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of June, in the year of
our Lord One thousand cight hundred and sixty-eight, in the thirty-

Her special licence that we, the said John Worth and Abraham Barker,
our executors, administrators, and assigns, or such others as we, the
said John Worth and Abraham Barker, 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 COVERING ROLLERS
AND CLEARERS USED IN MACHINERY FOR PREPARING AND SPINNING FIBROUS
MATERIALS," upon the condition (amongst others) that we, the said John

page_text: Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Scal 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 Worth and Abraham
Barker, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our Invention relates to certain improvements applicable to the
rollers or clearers used in machines for preparing and spinning wool,
flax, and other fibrous or textile materials, and consists in applying
between the usual leather covering and the body of the roller a sub-
stratum or foundation of woollen cloth or fabric combined with linen
or cotton cloth.
The woollen fabric may be felted or woven, but we prefer the felted
fabric, and this may to a certain extent be mixed with other fibrous
materials, as is now practised. We then cement upon such fabric
linen or cotton cloth, and cover the body of the roller with the com-
bined fabrics, after which the ordinary external covering of leather is
to be applied in the usual manner. In some cases we dispense with
the covering of linen or cotton cloth on the woollen cloth, felt, or
mixed fabric, and apply the leather covering to the woollen or mixed
fabric.
Having now described the. nature of our said Invention, and the
manner in which the same is to be performed, we would remark in
conclusion that we do not limit ourselves to the precise details we have
expressed, as the same may be slightly modified or varied without
departing from the object of the Invention; but what we claim and
desire to be secured to us by the herein in part recited Letters Patent is,
the improved method of covering the rollers or clearers of machines for
preparing and spinning fibrous materials by the application between the
body of the roller and the external leather covering of a felted or woven
fabric, either mixed or not with other fibrous materials, and covered or

page_text: not with linen or cotton cloth by means of an adhesive cement or
solution, substantially as herein specified..
In witness whereof, we, the said John Worth and Abraham Barker,
have hereunto set our hands and seals, this Twenty-fifth day of
November, in the year of our Lord One thousand eight hundred
and sixty-eight.
Witness,
HENRY DEAN BUTTERWORTH,
