PROVISIONAL SPECIFICATION left by the said Henry Walker at the
Office of the Commissioners of Patents, with his Petition, on the

I, HENRY WALKER, of Mirfield, in the County of York, Manu-
facturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CARD CLOTHING OF CARDING ENGINES," to be as
follows:-
This Invention consists in the employment of a fabric composed of
linen warp and the weft made of the hair of cows, goats, horses, or
other animals whose hair is of like nature and in which fabric the oil,
grease, or other lubricating matters, and in the manufacture thereof
is retained or allowed to remain (or I may apply oil or other lubri-
cating matters to such fabrics) which will act as a preventative to
corrosion of the wire card teeth and the expansion. or contraction of
the fabric.

on the 21st July 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
WALKER, of Mirfield, in the County of York, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of January, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said. Henry Walker, Her special licence that
I, the said Henry Walker, my executors, administrators, and assigns,
or such others as I, the said 'Henry Walker, my executors, adminis-
trators, 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 CARD
CLOTHING OF CARDING ENGINES," upon the condition (amongst others)
that I, the said Henry Walker, 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 Henry Walker, 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:-
.
This Invention consists in the employment of a fabric for this
purpose composed of linen warp, and the weft made of the hair of
cows, goats, horses, or other animals, and in which fabric the oil;
grease, or other lubricating matters used in the manufacture thereof
is retained or allowed to. remain (or I may apply oil or other lubri
cating matters to such fabrics) which will act as a preventative to
.

page_text: corrosion of the wire card teeth and the expansion or contraction of
the fabric.
In carrying this Invention into practical operation or in the spinning
of the weft yarns I may combine a little of some other fibrous substances
with the linen for the warp, or I may also combine some kinds of hair
with the linen for the warp, and I do not confine myself to any particular
kind of animal hair, but may use any kind that is capable of being
spun either alone or in combination with fibrous substances. Nor
do I limit or restrict myself to the kind of oil or grease used in the
manufacture or to be applied to this fabric, my object being to obtain
or produce and employ a fabric or material for card clothing that will
be less costly and yet non-clastic or as much so as possible and durable,
also such that will not corrode the wire of the card teeth as is the case
with clothing heretofore in use. The manner of using this fabric for
card clothing is the same as with other kinds of material.
Having thus described the nature and particulars of the said Invention
I would have it understood that what I claim as of my Invention is,
the use of a fabric composed of linen and hair and with oil, grease,
or other matters of a lubricating nature therein for the card clothing.
of carding engines.
In witness whereof, I, the said Henry Walker, have hereunto set.
my hand and seal, this Nineteenth day of July, in the year of our
Lord One thousand cight hundred and seventy-one.
Signed, scaled, and delivered
by the within-named Henry
Walker, in the presence of

Clerk to W. Tasker,
