County of Lancaster, Cotton Mill Manager, for the Invention of "IMPROVE-
MENTS IN CARDING ENGINES FOR CARDING COTTON AND OTHER FIBROUS
SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Abraham Holden at the Office
of the Commissioners of Patents on the 3rd April 1878.
ABRAHAM HOLDEN, of Little Hulton, near Bolton, in the County of Lancaster,
Cotton Mill Manager. "IMPROVEMENTS IN CARDING ENGINES FOR CARDING COTTON
AND OTHER FIBROUS SUBSTANCES."
My Invention consists of an improved combination of machinery for cleaning
fibrous substances from impurities.
In performing my Invention I make use of a main cylinder with rollers and
clearers of the ordinary construction.
My improvements consist in placing a clearer roller over the licker-in, which I set
to the licker-in and main cylinder. Above this clearer I place a working roller,
which is set to the main cylinder, and is cleared by the clearer. In front of the
clearer I place a roller for catching dirt, motes, and other impurities from the clearer.
This dirt roller is set to the licker-in and clearer. The clearer also cards with the
dirt roller and licker-in, as well as cleans the working roller above it. The clearer
is cleaned by the main cylinder. This dirt roller revolves very slowly, and is
stripped by a vibrating doffing comb or card on the top, and forms the strippings
into a roll or fleece.
I also place a card roller over the junction of the main cylinder and finishing
doffer cylinder. The card teeth of this roller card point to point, and meet the
main cylinder and doffer face to face. This roller takes a part of the fibres from the
main cylinder and puts them on the doffer; by this means the main cylinder is
acted upon twice, consequently the main cylinder gets two skimmings of clean
וע...

page_text: fibres, and is thereby comparatively free from fibres after passing the finishing
doffer. In front of this roller when facing the doffer I place another dirt roller,
covered with suitable card clothing; this roller is stripped by a vibrating comb or
card, and forms a roll of strippings on its upper surface. I also place a card roller
above the roller acting on the doffer, which cards point to point and face to face
with the main cylinder. It also cards point to point and face to face with the first
roller.
On one of the working rollers is an eccentric which moves a forked lever; this
lever imparts a to-and-fro motion to side rails, which impart a to-and-fro motion to
the doffing combs of the dirt rollers, which are turned round by ratchet wheels and
catch levers.
The dirt roller, with the doffing comb above described, may be applied to other
rollers of the carding engine.
The advantages of this Invention are a great carding surface and an abundance
of card wire at work, therefore great carding power; also running the machines
much slower than heretofore, therefore employing less steam power, oil, wear and
tear, labour, and less danger to the employer, consequently a cleaner machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Abraham Holden in the Great Seal Patent Office on the 1st October
1878.
ABRAHAM HOLDEN, of Little Hulton, near Bolton, in the County of Lancaster
Cotton Mill Manager. IMPROVEMENTS IN CARDING ENGINES FOR CARDING COTTON
"
AND OTHER FIBROUS SUBSTANCES."
My Invention consists of an improved combination of machinery for carding
and cleaning fibrous substances.
And in order that my Invention may be fully understood I will proceed to
describe the accompanying Drawing, which represents the principal parts of a
carding engine, to which my improvements are applied.
a is the lap roller for unrolling the fleece of fibres, which are carried over the
plate b, and delivered by the feed roller c to the licker-in d; e is the main cylinder ;
and g, the workers and clearers; and h, the doffer, all of which are made as
usual.
My improvements consist in placing the clearer roller i over the licker-in d, which
clearer roller is set to the licker-in d and to the main cylinder c. Above this clearer
I place the working roller j, which is set to the main cylinder, and is cleared by the
clearer i. In front of the clearer i is placed the roller k for catching dirt, motes,
and other impurities from the clearer i. This dirt roller
and clearer. The clearer i also cards with the dirt roller
as cleans the working roller j above it. The clearer
cylinder. The dirt roller revolves very slowly, being actuated by a worm on the
is set to the licker-in d
and licker-in d, as well
is cleaned by the main

page_text: axle of the feed roller c gearing into a pinion on the short diagonal shaft l, on which
is another worm gearing into a pinion on the axle of the dirt roller k, and it is
stripped on the top by the vibrating doffing comb m or card, and forms the strippings
into a roll or fleece.
The comb is worked by eccentrics on the axle of the roller ;, which eccentrics
give a to-and-fro motion to the brackets m³, to which the ends of the comb m are
fixed.
The card or skimming roller
is placed over the junction of the main cylinder e
and finishing doffer cylinder h. The card teeth of the roller n card point to point,
and meet the wires of the main cylinder face to face. This roller takes a part of
the fibres from the main cylinder and puts them on the doffer h; by this means the
main cylinder is acted upon twice, consequently the main cylinder gets two
skimmings of clean fibres, and is thereby comparatively free from fibres after
passing the finishing doffer. In front of this roller n, when facing the doffer h, is
placed another dirt roller o, covered with suitable card clothing; this roller is
stripped by the vibrating comb p, or by a card, and forms a roll of strippings on its
upper surface. The card roller q is placed above the roller n, and cards point to
peint and face to face with the main cylinder. It also cards point to point and face
to face with the roller n.
On the axle of the last working roller fare two eccentrics which actuate the
brackets pl, which impart a to-and-fro motion to the doffing comb p of the dirt
roller o, which is turned slowly round by a worm on the axle of the doffer h gearing
into a pinion on the upright shaft 8, and a worm on the upper end of the said shaft
gearing into a pinion on the axle of the dirt roller o.
Above the doffer and concentric to the skimming roller n is the trough t, the
object of which is to collect the motes and dirt thrown off by the roller n.
The rollers and are driven by a band from the main cylinder, as shewn.
The dirt rollers, with doffing combs above described, may be applied to other
rollers of the carding engine, and also to double carding engines.
The advantages of this Invention are a great carding surface and an abundance
of card wire at work, whereby great carding power is obtained; also the machine
may be worked much slower thau heretofore, therefore employing less steam power
and effecting a saving in oil and in the wear and tear.
Having thus stated the nature of my Invention, and described a convenient
mode of performing the same, I wish it to be understood that I do not intend
to limit myself to the details given, as the same can be considerably varied or
nodified. I claim,-
First. The rollers marked i, j, and , in combination with the licker-in d, when
applied to single or double carding engines, and acting in the manner described.
Secondly. The rollers marked n, q, and o, in combination with the duffer h, when
applied to single or double carding engines, and acting in the manner described.
In witness whereof, I, the said Abrahain Holden, bave hereunto set my hand
and seal, this Twenty-eighth day of September, One thousand eight hundred
and seventy-eight.
