Year: 1859

page_text: LETTERS PATENT to David Moseley, of the Chapel Field Works, Ardwick,
in the City of Manchester, Manufacturer of India-rubber and Gutta
Percha, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
CARRO DAD CARNING COTTON AND OTHER FIBROUS MATERIALS."
Sealed the 29th September 1859, and dated the 7th April 1859.
PROVISIONAL SPECIFICATION left by the said David Moseley at
the Office of the Commissioners of Patents, with his Petition, on the
7th April 1859.
I, DAVID MOSELEY, of the Chapel Field Works, Ardwick, in the City of
Manchester, Manufacturer of India-rubber and Gutta Percha, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MANU-
PACTURE OF CARDS FOR CARDING COTTON AND OTHER FIBROUS MATERIALS," to be as
follows:-
The nature of my Invention consists in manufacturing the backs of cards of
cloth composed of woollen weft and cotton or linen warp, covered with a sheet.
of india-rubber in its native state, cut from a cylindrical block. In performing.
my Invention the sheet of native india-rubber is attached to the fabric by.
cement, and it may be used in its natural state, or it may be subjected to the.
influence of chloride of sulphur, for the purpose of imparting to it greater.
elasticity, durability, and strength.
My Invention also consists in combining native sheet india-rubber acted
upon by chloride of sulphur with cotton or other fabrics. The card teeth aro
set in the backs thus prepared in the ordinary manner.

by the said David Moseley in the Great Seal Patent Office on the
7th October 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
MOSELEY, of the Chapel Field Works, Ardwick, in the City of Manchester,
Manufacturer of India-rubber and Gutta Percha, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of April, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said David Moseley, Her special licence that I, the said David
Moseley, my executors, administrators, and assigns, or such others as
I, the said David Moseley, my 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
night 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 THE MANUFACTURE OF CARDS FOR CARDING COTTON AND
OTHER FIBROUS MATERIALS," upon the condition (amongst others) that I, the
said David Moseley, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, 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 1, the said David Moseley, do hereby declare
the nature of my 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) :-
:-
The nature of my Invention consists in manufacturing the backs of cards of
cloth composed of woollen weft and cotton or linen warp, covered with a sheet
of india-rubber in its native state, cut from a cylindrical block.
The sheet of native india-rubber is attached to the fabric by cement, and it
may be used in its natural state, or subjected to the influence of chloride of
sulphur, for the purpose of imparting to it greater elasticity, durability, and
strength. My Invention also consists in combining native sheet india-rubber,
acted upon by chloride of sulphur, with cotton or other fabrics. The card
teeth are set in the backs thus prepared in the ordinary manner.

page_text: In performing my Invention, the cloth composed of cotton or linen warp
threads, and woollen weft threads, is woven in a loom of the ordinary con-
struction, and a sheet of native india-rubber cut from a cylindrical block, in
the manner described in the Specification of Letters Patent, granted to me on
the Twenty-second of January, One thousand eight hundred and fifty-nine,
Number 201, or by any other suitable means, are united together by cement,
thereby forming a strong clastic and durable back for cards, into which back
the card teeth are set in the ordinary manner. When it is requisite to
increase the strength, clasticity, and durability of the card backs, I subject the
sheet of native india-rubber, after it is cemented to the cloth or otherwise, to
the influence of chloride of sulphur; after this process has been performed,
the india-rubber is washed with a weak solution of quicklime, or with a
solution of caustic alkali, and then it is exposed to the atmosphere in order to
neutralize the acid in the chloride of sulphur; the india-rubber is then washed
in clean water. If found requisite, French chalk may be applied to the
surface of the india-rubber to prevent any adhesion of the card back, in passing
through the rollers of the card setting machine.
Another part of my Invention consists in manufacturing card backs of
cotton or other fabrics united to native sheet india-rubber acted upon by
chloride of sulphur.
Having thus described the nature of my Invention, and the means of per-
forming the same, I wish it to be understood that I am aware card backs
have been made of various descriptions of woven fabrics, combined with or
united to preparations of india-rubber; I therefore restrict my claims to manu-
facturing card backs of a fabric composed of cotton or linen warp threads,
and woollen weft threads, united to a sheet of native india-rubber, either in its
natural state, or subjected to the influence of chloride of sulphur, as described;
and I also claim the manufacturing of card backs of cotton or other woven
fabrics united to native sheet india-rubber acted upon by chloride of sulphur.
In witness whereof, I, the said David Moseley, have hereunto set my
hand and seal, this Sixth day of October in the year of our Lord
One thousand eight hundred and fifty-nine.
Witness,
II. B. BARLOW,
DAVID MOSELEY. (L.S.)
Manchester.
