Year: 1875

page_text: LETTERS PATENT to Ernest Grether, of Blackfriars Street, Manchester,
in the County of Lancaster, for the Invention of "IMPROVEMENTS
IN CARD CLOTH OR FOUNDATION MATERIAL FOR USE IN THE MANUFACTURE OF
Sealed the 14th March 1876, and dated the 17th September 1875.
PROVISIONAL SPECIFICATION left by the said Ernest Grether at
the Office of the Commissioners of Patents, with his Petition, on
the 17th September 1875.
I, ERNEST GRETHER, of Blackfriars Street, Manchester, in the County
of Lancaster, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CARD CLOTH OR FOUNDATION MATERIAL FOR USE IN THE MANU-
FACTURE OF THE CARDS EMPLOYED IN THE CARDING OF TEXTILE MATERIALS AND
FABRICS," to be as follows:-
.My Invention relates to the foundation material used in the manu-
facture of cards employed in the carding of cotton, wool, silk, flax, and

page_text: other fibrous and textile materials, and in the finishing of woven fabrics
and for other purposes.
Previously to my Invention the materials ordinarily employed in the
said manufacture have been leather, fabrics of woolen, cotton, linen,
and jute, and caoutchouc, either_separately-or in combination. In lieu
-of such materials or in combination with some or with any of them I
employ a material composed wholly or principally of particles of cork
cemented together or caused to cohere, and formed into sheets of a
suitable thickness.
I do not consider it necessary to describe the method of manufacturing
the said material more minutely as the process is the same as or similar
to that employed in the manufacture of cork carpet and kamptųlicon,
and such materials may be taken as the basis of my foundation without
especially manufacturing them for the purpose. I take the material so
formed and I cement to one or to both sides of the same woolen, linen,
cotton, or other textile or felted fabrics, caoutchouc or other suitable
cement being employed. The-nature-and-the thickness of the material
so cemented to the cork fabric varies with the purposes for which the
cards are required.<.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in
the fortieth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Ernest Grether, Her special
licence, that I, the said Ernest Grether, my executors, administrators,
and assigns, or such others as I, the said Ernest Grether, my exe-
cutors, administrators, and assigns, should at any time agree with, and

page_text: 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 "IMPROVE-
5 MENTS IN CARD CLOTH OR FOUNDATION MATERIAL FOR USE IN THE MANUFACTURE
OF THE CARDS EMPLOYED IN THE CARDING OF TEXTILE MATERIALS AND FABRICS,"
upon the condition (amongst others) that I, the said Ernest Grether, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
O 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 I, the said Ernest Grether, do hereby declare
the nature of the said 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 :-
My Invention relates to the foundation material used in the manu-
facture of cards employed in the carding of cotton, wool, silk, flax, and
other fibrous and textile materials, and in the finishing of woven fabrics
and for other purposes.
Previously to my Invention the materials ordinarily employed in the
said manufacture have been leather, fabrics of woolen, cotton, linen,
and jute, and caoutchouc either separately or in combination. In lieu
of such materials or in combination with some or with any of them I
employ a material composed wholly or partially of particles of cork
cemented together or caused to cohere, and formed into sheets of a
suitable thickness.
I do not consider it necessary to describe the method of manufacturing
the said material more minutely as the process is the same as or similar
to that employed in the manufacture of cork carpet and kamptulicon,
and such materials may be taken as the basis of my foundation without
specially manufacturing them for the purpose. I take the material so
formed and I cement to one or to both sides of the same woolen, linen,
cotton, or other textile or felted fabrics, caoutchouc or other suitable
cement being employed. The nature and thickness of the material so

page_text: cemented to the cork fabric varies with the purposes for which the cards
are required.
For most purposes I prefer to apply the textile or felted fabrics only
to the sido which is to form the front of the foundation, but the said
material may form the back thereof, or be applied to both sides of the
In witness whereof, I, the said Ernest Grether, have hereunto set
my hand and seal, this Fifteenth day of March, in the year of
our Lord One thousand eight hundred and seventy-six.
