Year: 1873

page_text: LETTERS PATENT to Henry Mitchell Kelshaw, of Elland, in the County
of York, Card Manufacturer, for the Invention of "IMPROVEMENTS
IN WIRE CARD COVERING FOR CARDING WOOL, COTTON, SILK, FLAX, Tow, and
OTHER FIBROUS SUBSTANCES."
Sealed the 20th October 1873, and dated the 2nd May 1873.
PROVISIONAL SPECIFICATION left by the said Henry Mitchell Kel-
shaw at the Office of the Commissioners of Patents, with his
Petition, on the 2nd May 1873.
I, HENRY MITCHELL KELSHAW, of Elland, in the County of York,
Card Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN WIRE CARD COVERING FOR CARDING WOOL, COTTON, SILK,
FLAX, TOW, AND OTHER FIBROUS SUBSTANCES," to be as follows:-
Heretofore in the manufacture of "cards" employed in carding
engines and other machinery for manufacturing wool, cotton, silk, flax,
tow, and other fibrous substances, the foundation or substance in which
the teeth are fixed has been made of leather, cloth, and india-rubber,
which is not only expensive in the first cost, but will not withstand the

page_text: damaged.
Now my improvements consist in making the foundation or material
in which to fix the teeth of such "cards" of Mackintosh cloth, felting
paper, or a cloth composed of woollen and cotton, and covering the same 5
with a thin layer of lead, zinc, tin, copper, or other suitable metal or
material. By this means I am enabled to make card covering at a much
cheaper cost, and of a far more durable character.
'
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Henry Mitchell Kelshaw in the Great Seal 1
Patent Office on the 31st October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
MITCHELL KELSHAW, of Elland, in the County of York, Card Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 1
Letters Patent, bearing date the Second day of May, in the year of '
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Henry Mitchell Kelshaw, Her special
license that I, the said Henry Mitchell Kelshaw, my executors, a
administrators, and assigns, or such others as I, the said Henry
Mitchell Kelshaw, 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 WIRE CARD COVERING FOR CARDING WOOL, COTTON,
SILK; FLAX, Tow, AND OTHER FIBROUS SUBSTANCES," upon the conditions
(amongst others) that I, the said Henry Mitchell Kelshaw, 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

page_text: NOW KNOW YE, that I, the said Henry Mitchell Kelshaw, 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 :-
Heretofore in the manufacture of "cards" employed in carding engines
and other machinery for manufacturing wool, cotton, silk, flax, tow, and
other fibrous substances, the foundation or substance in which the teeth
are fixed has been made of leather, cloth, and india-rubber, which is not
only expensive in the first cost, but will not withstand the action of oil
to which it is liable to come into contact and be damaged.
Now my improvements consist in making the foundation or material
in which to fix the teeth of such "cards" of Macintosh cloth, felting,
paper, or a cloth composed of woollen and cotton, and covering the
same with a thin layer of lead, zinc, tin, copper, or other suitable metal
or material. By this means I am enabled to make card covering at a
much cheaper cost, and of a far more durable character.
Having thus described the nature of this my said Invention, and shewn
in what manner the same is or may be performed, I would have it
understood that I do not confine myself to the particular use of any
metal or material, but what I do claim and believe to be new within the
realm is, the application of lead or other metal in the manufacture of
card covering, substantially as explained and described.
In witness whereof, I, the said Henry Mitchell Kelshaw, have
hereunto set my hand and seal, this Twenty-ninth day of
October, One thousand eight hundred and seventy-three.
HENRY MITCHELL KELSHAW. (L.S.) ·

within-named Henry Mitchell
Kelshaw, in the presence of
