Year: 1869

page_text: LETTERS PATENT to Albert Thornton, of the Firm of John Thornton
and Sons, of Cleckheaton, in the County of York, Machine Makers,
and Ben Senior, of Heckmondwike, in the said County, Overlooker,
for the Invention of "IMPROVEMENTS IN CARDING ENGINES, OR MACHINERY
FOR CARDING WOOL OR OTHER FIBROUS SUBSTANCES.”
Sealed the 29th April 1870, and dated the 1st November 1869.
PROVISIONAL SPECIFICATION left by the said Albert Thornton and
Ben Senior at the Office of the Commissioners of Patents, with
their Petition, on the 1st November 1869.
We, ALBERT THORNTON, of the Firm of John Thornton and Sons, of
Cleckheaton, in the County of York, Machine Makers, and BEN SENIOR, (
of Heckmondwike, in the said County, Overlooker, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN CARDING ENGINES, OR
MACHINERY FOR CARDING WOOL OR OTHER FIBROUS SUBSTANCES," to be as
follows:-
This Invention relates to the scribber carding engine, and to the
means of doffing or stripping the carded fibre from the doffer cylinder.

page_text: Heretofore this has been effected by "doffing plates or oscillatory
comb plates, which in the working or doffing some kind of fibrous
substance, such as dirty or greasy wool, soon become choked, or the
teeth filled with dirt and grease, rendering them inoperative until
cleansed.
Now our improvements consist in dispensing with these combs, and
instead we apply a card stripper or roller clothed or covered with cards
to rotate in contact with the doffer cylinder at a suitable surface speed,
which thereby doffs or strips the carded fibre from the teeth of the doffer,
and a plain roller rotating in contact with this said card roller removes
the fibre therefrom and lays it upon the creeper or endless apron, which
carries it away in the usual manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Albert Thornton and Ben Senior in the Great
Seal Patent Office on the 30th April 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ALBERT
THORNTON, of the Firm of John Thornton and Sons, of Cleckheaton, in
the County of York, Machine Makers, and BEN SENIOR, of Heckmond-
wike, in the said County, Overlooker, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of November, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Albert Thornton and Ben Senior, Her special
licence that we, the said Albert Thornton and Ben Senior, our executors, 2
administrators, and assigns, or such others as we, the said Albert
Thornton and Ben Senior, our 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 3
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN CARDING ENGINES, OR MACHINERY
FOR CARDING WOOL OR OTHER FIBROUS SUBSTANCES," upon the condition
(amongst others) that we, the said Albert Thornton and Ben Senior,
our executors or administrators, by an instrument in writing under our, 3

page_text: or their, or one of our or 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 we, the said Albert Thornton and Ben Senior,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying Sheet of Drawings
(that is to say):-
This Invention relates to the scribber carding engine, and to the
means of doffing or stripping the carded fibre from the doffer cylinder.
Heretofore this has been effected by "doffing plates" or oscillatory
comb plates, which in the working or doffing some kinds of fibrous
substance, such as dirty or greasy wool, soon become choked, or the
teeth filled with dirt and grease, rendering them inoperative until
cleansed.
Now our improvements consist in dispensing with these combs, and
instead we apply a card stripper or roller clothed or covered with cards
to rotate in contact with the doffer cylinder at a suitable surface speed,
which thereby doffs or strips the carded fibre from the teeth of the doffer,
and a plain roller rotating in contact with this said card roller removes
the fibre therefrom, and with the aid of another plain roller lays it
upon the creeper or endless apron, which carries it away in the usual.
manner.
The Invention will be readily understood by reference to the accom

page_text: indicated by the arrow, which roller D removes the fibre from the card
roller; and E is another plain roller constructed (of tin or other suitable
material) with or without axis, but resting upon the creeper, and rotating
by contact therewith in the direction of the arrow; and in order that
this roller E may always remain in contact with the roller D to prevent
the fibre following it the upper part of the creeper is lifted and supported
by a roller G which is carried in suitable bearings, and thus forming an
inclino on that part of the said creeper where the roller rests, whereby
the carded fibre is laid upon the creeper, which carries it away in the
usual manner.
Having thus fully described the nature of our said Invention, and
shewn by Drawings how the same is performed or carried into practical
operation, we would have it understood that what we claim as our
Invention is, the application to and use in connection with carding
engines of a card stripper or card roller in combination with plain
rollers applied and operated in manner and for purposes substantially
as herein described and shewn by the accompanying Sheet of Drawings.
In witness whereof, I, the said Ben Senior, for and on behalf of
myself and the said Albert Thornton, have hereunto set my hand
and scal, this Twenty-eighth day of April, in the year of our
Lord One thousand eight hundred and seventy.
Signed, sealed, and delivered by the
within-named Ben Senior, in the
presence of
