PROVISIONAL SPECIFICATION left by the said Joseph Walker and
James Barnes at the Office of the Commissioners of Patents, with their
Petition, on the 8th April 1861.
We, JOSEPH WALKER, of Oakenshaw, in the County of Lancaster, and
JAMES BARNES, of the same Place, India-rubber Manufacturers, do hereby
declare the nature of the said Invention for "AN IMPROVEMENT IN THE MANU-
FACTURE OF CARD CLOTH' USED FOR CARDING COTTON, WOOL, AND OTHER FIBROUS
SUBSTANCES," to be as follows:-
The ordinary card cloth used as a foundation for wire cards is composed of
a textile fabric treated or prepared with india-rubber, and becomes rotten or
unsound by contact with oil or grease, either from the machinery or contained
in the substance to be carded, and is more especially acted upon in carding
wool. Our Invention consists in applying to, coating, covering, or otherwise
treating the said "card cloth" with a varnish or enamel, thereby rendering it
impervious to grease, or oil, or other deleterious matter.

months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Walker, do hereby declare the
nature of our said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
The ordinary card cloth used as a foundation for wire cards is composed of
a textile fabric treated or prepared with india-rubber, and becomes rotten or
unsound by contact with oil or grease, either from the machinery or contained
in the substance to be carded, and is more especially acted upon in carding
wool. Our Invention consists in applying to, coating, covering, or otherwise
treating the said "card cloth" with a varnish or enamel, thereby rendering it
impervious to grease or oil or other dileterious matter.
We wish it to be distinctly understood that we claim coating or covering or

page_text: otherwise treating the fabric known as the "card cloth" with a protecting
varnish or enamel, in order to render it impervious to matter of an unctuous
and deleterious nature.
In witness whereof, I, the said Joseph Walker, have hereunto set my
hand and seal, this Fifth day of October, in the year of our Lord
One thousand eight hundred and sixty-one.
