for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF WIRE

Office of the Commissioners of Patents, with his Petition, on the
26th January 1872.
I, WILLIAM WALTON, of Haughton Vale Works, Denton, near the
City of Manchester, Wire Card Manufacturer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
WIRE CARDS," to be as follows :—

page_text: consists in rolling ordinary round wire into an angular section with
rounded ends, and then setting the card teeth made from such angular
wire into prepared india-rubber cloth or other material by means of the
usual machinery, in such wise that the finer end of the section of angular
wire teeth first strikes into the cotton or other fibre to be carded,
and the broader end of the said section abuts against the india-rubber
cloth or other material in which the teeth are set.
By the application of angular wire rolled into the section above described
I obtain the desired sharpness of front edge for penetrating, seperating,
and carding the fibres, and the required breadth in the back of the teeth
to avoid the elongating of the hole in the india-rubber cloth or other
material by the strain that is put on the card teeth when the cards are
at work
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Walton in the Great Seal Patent Office
on the 26th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WALTON, of Haughton Dale Works, Denton, near the City of Man-
chester, Wire Card Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of January, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said William Walton, Her special licence that I,
the said William Walton, my executors, administrators, and assigns, or
such others as I, the said William Walton, 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 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 THE MANUFACTURE OF WIRE
CARDS," upon the condition (amongst others) that I, the said William

page_text: Walton, 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 I, the said William Walton, 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):
It has heretofore been customary in manufacturing wire cards to use
drawn, round, or angle shaped wire, or rolled flat wire; now my Inven-
tion consists in rolling ordinary round or other wire into an angular
section, and then setting the card teeth made from such angular wire
into prepared india-rubber cloth or 'other material by means of the usual
machinery, in such wise that the finer end of the section of angular wire
teeth first strikes into the cotton or other fibre to be carded, and the
broader end of the said section abuts against the india-rubber cloth or
other material in which the teeth are set.
By the application of rolled angular wire I obtain the desired sharpness
of front edge for penetrating, separating, and carding the fibres, and the
required breadth in the back of the teeth to avoid the elongating of
the hole in the india-rubber cloth or other material by the strain that is
put on the card teeth when the cards are at work.
Another great advantage of my improved wire cards is that in con-
sequence of the wire being rolled instead of drawn, as heretofore, the
front edge of the wire becomes hardened under the pressure of the
rollers, and wire cards made of such wire are more durable, and do not
require to be ground or set so often as those heretofore employed.
Having thus stated the nature and particulars of my Invention, I wish
it to be understood that I am aware that drawn angle wire has been
used for making the coarser description of wire cards, but that such
drawn angle wire was considered unfit for making fine card fillets for
general use; I therefore make no claim to angle wire, except when it

page_text: is produced by rolling, and I declare that I claim as my improvements
in the manufacture of wire cards, the application and use of rolled
angular wire as described.
In witness whereof, I, the said William Walton, have hereto set
my hand and seal, this Twenty-third day of July One thousand i
eight hundred and seventy-two.
