CERTAIN IMPROVEMENTS IN CARDING ENGINES
Year: 1857

page_text: LETTERS PATENT to John Milne, of Royton, in the County of Lancaster,
Cotton Spinner, for the Invention of "CERTAIN IMPROVEMENTS IN CARDING
ENGINES."
Sealed the 20th April 1858, and dated the 22nd October 1857.
PROVISIONAL SPECIFICATION left by the said John Milne at the
Office of the Commissioners of Patents, with his Petition, on the
22nd October 1857.
I, JOHN MILNE, of Royton, in the County of Lancaster, Cotton Spinner, do
hereby declare the nature of my said Invention for "CERTAIN IMPROVEMENTS
IN CARDING ENGINES," to be as follows:-
My improvements consist in the employment and use of an additional or
extra roller or rollers, covered with cards, and placed beneath the ordinary
"taker-in" roller of the carding engine; the points of the cards on the extra
roller project towards or against those of the "taker-in." The "taker-in"
roller revolves at a higer speed than the extra roller, and thus delivers the
cotton on to the main cylinder, and the extra cylinder revolving slowly causes
the cotton to be carded and cleared from dirt, which would otherwise be
taken on to the main cylinder; by this means also the fibre is worked much
finer, and less waste is caused than heretofore.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MILNE, of Royton, in the County of Lancaster, Cotton Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of October, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Milne, Her especial license that I, the said John
Milne, my executors, administrators, and assigns, or such others as I,
the said John Milne, 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 "CERTAIN IMPROVEMENTS IN CARDING ENGINES," upon the condition, amongst
others, that I, the said John Milne, by an instrument in writing under my
hand and seal, 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 John Milne, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-
My improvement consists in the employment and use of an additional or
extra roller or rollers covered with cards, and placed beneath the ordinary
"taker-in" roller of the carding engine; the points of the card on the extra
roller project towards or against those of the "taker-in." The "taker in"
roller revolves at a higher speed than the extra roller, and thus delivers the
cotton on to the main cylinder, and the extra cylinder revolving slowly causes
the cotton to be carded and cleared from dirt, which would otherwise be
taken on to the main cylinder; by this means also the fibre is worked much
finer, and less waste is caused than heretofore.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings, made upon a scale of

page_text: about
to a foot, and having similar letters of reference marked
upon corresponding parts.
Fig. 1 is a side elevation of that portion of the carding engine to which
the improvement is applied, and is shewn attached; and Fig. 2 is a sectional
view of the same, illustrative of another arrangement or extension of the
improvement. In Fig. 1, a, a, is the framing of the carding engine, and b
the main carding cylinder; c is the "taker in" roller; and d, d, d, d, are the
ordinary lap and carrier rollers; e is the extra roller before named for clearing
the cotton from dirt or extraneous matter, which would otherwise be carried
on to the main carding cylinder.
Fig. 2 illustrates the adaptation of two or more of these extra cylinders,
such arrangement effecting a more perfect cleaning of the cotton, and by such
means the fibre may be worked much finer, and in such cases the diameter
of the "taker-in" must be enlarged. The extra rollers e, e, may be made
adjustable to any distance or angle to or from the "taker-in," by means of the
levers f, f, in which it bears, which can be regulated by screws and nuts.
Having now described the nature of my said Invention, together with the
method of performing the same, I wish it to be distinctly understood that I
claim the novel employment, application, and use of one or more extra
cylinders or rollers placed beneath and in contact with the "taker-in roller,"
for the purpose of cleaning the cotton before passing on to the main carding
cylinder, and also effecting better carding with less waste of cotton than
hitherto, as herein-before described, set forth, and fully exhibited in the
Drawings attached.
In witness whereof, I, the said John Milne, have hereunto set my hand
and seal, this Twentieth day of April, in the year of our Lord One
thousand eight hundred and fifty-eight.
JOHN MILNE. (L.S.)
