IMPROVEMENTS IN CARDING ENGINES
Year: 1871

page_text: LETTERS PATENT to Charles Parkinson, of Bolton, in the County of
Lancaster, Manager, and Robert Henry Lord, of the same Place,
Cotton Spinner, for the Invention of "IMPROVEMENTS IN CARDING
ENGINES."
Scaled the 11th August 1871, and dated the 8th March 1871.
PROVISIONAL SPECIFICATION left by the said Charles Parkinson and
Robert Henry Lord at the Office of the Commissioners of Patents,
with their Petition, on the 8th March 1871.
We, CHARLES PARKINSON, of Bolton, in the County of Lancaster,
Manager, and ROBERT HENRY LORD, of the same Place, Cotton Spinner,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN CARDING ENGINES," to be as follows:-
Our Invention consists in applying under the licker in, or cylinder
which delivers the cotton or other fibres to the main cylinder, a roller
covered with needle point or other card teeth. The cotton or other
fibre is combed by the licker in combined with the toothed roller, and

page_text: the surface of this roller is stripped by means of a doffing comb actuated
by a crank or eccentric.
In some cases two combs may be applied, that is to say, one to the
oothed roller and one to the main cylinder.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Parkinson and Robert Henry Lord in the
Great Seal Patent Office on the 7th September 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
PARKINSON, of Bolton, in the County of Lancaster, Manager, and
ROBERT HENRY LORD, of the same Place, Cotton Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of March, 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 us, the said Charles Parkinson and Robert Henry
Lord, Her special licence, that we, the said Charles Parkinson and
Robert Henry Lord, our executors, administrators, and assigns, or
such others as we, the said Charles Parkinson and Robert Henry Lord,
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, excrcise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN CARDING ENGINES," upon the condition (amongst others)
that we, the said Charles Parkinson and Robert Henry Lord, our exc-
cutors or administrators, by an instrument in writing under our, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Charles Parkinson and Robert
Henry Lord, do hereby declare the nature of our said Invention, and in

page_text: what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement (that is to say):
Our Invention consists in applying under the licker in, or cylinder
which delivers the cotton or other fibres to the main cylinder, a roller
covered with needle point or other card teeth. The cotton or other
fibre is combed by the licker in combined with the toothed roller, and
the surface of this roller is stripped by means of a doffing comb actuated
by a crank or eccentric. In some cases two combs may be applied,
that is to say, one to the toothed roller and one to the main cylinder.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying
Drawing, which represents in section the principal parts of a carding
engine of the ordinary construction to which our improvements are
applied.
a is the lap of cotton or other fibres, which is supported on and
unwound by the rollers b, b. The lap is carried to the feed rollers c, c,
and delivered by them to the licker in d, from which it is carried forward
by the main cylinder e, and delivered to the doffer ƒ in the usual
manner.
is
Our improvements consist in applying the roller g to the under side
of the licker in d; this roller g is covered with necdle point or other card
teeth, and is turned slowly round by means of the pinion c¹ on the lower
feed roller c gearing into the wheel h, to which is fixed the pinion h³,
gearing into the wheel g¹ on the axle of the roller g, as shewn by the
dotted circles, or by any other suitable gearing; and the roller
stripped by the comb i, which is fixed to a cross bar supported by the
arms, keyed to the axle 2, and this axle is made to oscillate by
the wheel c fixed to the lower feed roller c gearing into the pinion j,
to which is connected a disc j³, from the face of which projects a crank
pin taking into a slot in the lever, keyed to the axle. The cotton
or other fibre is combed by the licker in d and the toothed roller g;
and the short fibres with the pieces of broken seed and other impurities
caught by the teeth of the roller 9 are stripped by the comb i, and aro
collected in a box placed under the feeding apparatus.
By this improved machinery a great part of the impuritics is removed
from the fibres before they arrive at the main cylinder, thereby producing
| better carding than heretofore.

page_text: In some cases we propose to apply a comb similar to that marked i,
to act on the surface of the main cylinder, to strip the impurities from
the card clothing before it arrives at the licker in.
Having thus stated the nature of our Invention, and described a
convenient mode of performing the same, we wish to remark that we 5
do not intend to limit ourselves to the details given, as the same may
be considerably varied or modified, and we claim,―
First. The application of the roller g to the licker in, in the manner
and for the purposes described.
And, secondly. The application of the doffing comb i to the roller g, 1
and to the main cylinder as described.
In witness wheroof, we, the said Charles Parkinson and Robert
Henry Lord, have hereto set our hands and scals, this Fifth
day of September One thousand eight hundred and seventy-one.
