CERTAIN IMPROVEMENTS IN CARDING ENGINES TO BE EMPLOYED FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1863

page_text: LETTERS PATENT to Richard Butterworth, of Failsworth, in the County
of Lancaster, Mechanic, for the Invention of "CERTAIN IMPROVEMENTS IN
CARDING ENGINES TO BE EMPLOYED FOR CARDING COTTON AND OTHER FIBROUS
SUBSTANCES."
Scaled the 2nd October 1863, and dated the 28th April 1868.
PROVISIONAL SPECIFICATION left by the said Richard Butterworth at
the Office of the Commissioners of Patents, with his Petition, on the
28th April 1863.
I, RICHARD BUTTERWORTH, of Failsworth, in the County of Lancaster,
Mechanic, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN CARDING ENGINES TO BE EMPLOYED FOR CARDING COTTON AND
OTHER FIBROUS SUBSTANCES," to be as follows:-
My Invention relates to that part of the carding engine known as the
"stripper," and is employed to strip the "fleece" or sheet of fibrous material
from the "doffing cylinder."
The Invention consists in the employment and use of an internal shaft
having a number of pins or points arranged in several spiral lines or otherwise
upon its periphery, and in enclosing such pins within a cylindrical casing
excepting at the point where they are required to protrude to strip the doffing
cylinder, such casing being perforated with holes corresponding to the pins,
through which they emerge and retire. The exterior casing is placed excen-
trically from the internal central shaft, its ends working on eccentrics, and it

page_text: is also provided with an internal ring of teeth taking into a pinion on the said
shaft, thus the casing being driven by a band and pulley causes the rotation of
the shaft, both revolving together, but excentrically to each other, which
causes the pins to emerge in succession from the perforations at a certain
point of the revolution to strip the fibrous material from the "doffer" and to
retire again within the cylinder, cleansing themselves against the sides of the
perforations.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Butterworth in the Great Seal Patent Office on the
28th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
BUTTERWORTHI, of Failsworth, in the County of Lancaster, Mechanic, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of April, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Richard Butterworth, Her special license that I, the said Richard
Butterworth, my executors, administrators, and assigns, or such others as
I, the said Richard Butterworth, 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 TO BE EMPLOYED FOR CARDING COTTON AND
OTHER FIBROUS SUBSTANCES," upon the condition (amongst others) that I, tho
said Richard Butterworth, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should parti-
cularly 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 Richard Butterworth, 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 and accompanying Drawings (that is to say):-

page_text: My Invention relates to that part of the carding engine known as the
"stripper," and is employed to strip the "fleece" or sheet of fibrous material
from the "doffing cylinder."
The Invention consists in the employment and use of an internal shaft
having a number of pins or points arranged in several spiral lines or otherwise
upon its periphery, and in enclosing such pins within a cylindrical casing
excepting at the point where they are required to protrude to strip the doffing
cylinder, such casing being perforated with holes corresponding to the pins,
through which they emerge and retire. This exterior casing is placed eccen-
trically from the internal central shaft, its ends working on eccentrics, and it
is also provided with an internal ring of teeth taking with a pinion on the said
shaft, thus the casing being driven by a band and pulley causes the rotation of
the shaft, both revolving together, but eccentrically to each other, which
causes the pins to emerge in succession from the perforations at a certain
point of the revolution to strip the fibrous material from the "doffer" and to
retiro again within the cylinder, cleansing themselves against the sides of the
perforations.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings, Fig. 1 being made upon
a scale of about three inches to the foot, and Figs. 2, 3, and 4, full size,
similar letters of reference being marked upon corresponding parts of the
apparatus.
Fig. 1 is an end view of that part of the carding engine containing the
"doffing cylinder," and to which the "stripper" is applied, which is shewn in
section; Fig. 2 is an end sectional view of the stripper and its covering
cylinder, to which a "guard" or "cleaner" is shewn applied, which is in
contact with the exterior surface of the cylinder, and prevents the fibrous
material from "lapping" thereupon; Fig. 3 is a view, shewn partly in section,
exhibiting the inner roller covered with points, and the external perforated
cylinder, the end of which turns upon the cam on the framing; this view,
together with Fig. 4, illustrates the method of driving the outer cylinder from
the inner roller.
In Fig. 1 a, a, represents a portion of the framing of a carding engine in
which the ordinary "doffing cylinder" 6 rotates; c is the bracket which
supports tho "stripping" apparatus, and which is secured the guide or cam d
(seen in Fig. 3), upon which the end of the perforated cylinder e revolves.
The shaft is driven by ordinary means and drives the roller g, in which the
stripping points are placed, and which, by means of the toothed wheel h,
secured to its end, gearing with an internal wheel i, effects the revolution of

page_text: the outer perforated case or cylinder c. The cam d is concentric with the
outer cylinder and eccentric to the internal roller, which causes the points to
protrude at one regular point in the revolution of the "stripper," as seen in
Fig. 2, and to retire again within the cylinder after having "stripped" the
fibrous material from the doffer. The perforated cylinder is partly encircled
by a "cleanerk, shewn in Fig. 2, which prevents that accumulation of fibrous
material thereupon termed "lapping." I would remark, that instead of points
or pins being inserted in the roller, it may be covered with fillets or bands of
points, like "cards," the points being properly arranged and set out for the
purpose.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim,-
First, the novel employment and use of a roller furnished with points to act
upon the fibrous material.
And, secondly, consists in an exterior perforated cylinder to rotate with it
eccentrically to the centre of such roller by the method shewn, so as to cause
the point to project at one given part of the revolution.
Thirdly, the method of driving the exterior cylinder from the roller.
And, lastly, I claim the general arrangement of apparatus as herein-before
described, set forth, and fully illustrated in the Drawings attached.
In witness whereof, I, tho said Richard Butterworth have hereunto set
my hand and seal, this Twenty-sixth day of October, in the year of our
Lord One thousand eight hundred and sixty-three.
