PROVISIONAL SPECIFICATION left by the said James Thomas Chadwick
and Joseph Crossley at the Office of the Commissioners of Patents on the
5th September 1883.
JAMES THOMAS CHADWICK of Salford and JOSEPH CROSSLEY of Bury both in the
County of Lancaster "IMPROVEMENTS IN ROLLERS EMPLOYED. IN MACHINERY OR
APPARATUS FOR PREPARING DRAWING DOUBLING AND SPINNING COTTON OR OTHER
FIBROUS SUBSTANCES
"
This invention relates to the leather covered rollers employed in machinery or
apparatus for preparing spinning and doubling cotton or other fibrous substances,
the object being to dispense with the ordinary leather covering and to, substitute
therefor a composition which shall be more economical both as regards the cost and
durability thereof.
For this purpose we take the roller after being covered with the thick roller
cloth, and first give it a coating of a composition or mixture of the following
ingredients, namely Linseed oil, rock ultramarine blue, lamp black and prepared
albumen, and we then place it in an oven or stove to be dried; when dry it is
again coated with the same composition and again dried in the same manner;
Afterwards we give it a final coating of a second composition consisting of Linseed
oil, ivory black and Prussian blue: it is then again placed in the oven or stove, to
be dried and set, and is then ready for use.
By this means a smooth and yielding surface is given to the rollers which will be
found to be more economical and durable than leather and also gives better results
in the production of the yarn and hence a better cloth.

composition, consisting of linseed oil five parts, Ivory black one and a quarter parts
and Prussian blue one and a quarter parts; it is then again placed in the oven
or stove to be dried and set, and is then ready for use.
By this means a smooth and yielding surface is given to the rollers, which will
be found to be more economical and durable than leather and also gives better
results in the production of the yarn and hence a better cloth.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
we claim as our invention the substitution, in the manufacture of rollers, employed
in machinery or-apparatus for preparing, drawing, doubling and spinning cotton or
other fibrous, substances, of the above compositions in the place of leatlier
substantially in the manner and for the purposes hereinbefore set forth.
In witness whereof I the said James Thomas Chadwick (on behalf of myself
and the said Joseph Crossley have hereunto set my hand and seal this fourth.
