"IMPROVEMENTS IN CARDING ENGINES."
My invention consists of an improved combination of machinery for cleaning
cotton and other fibre.
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 main cylinder, above this clearer I place a working roller, which is set to
the main cylinder, and is cleaned by the clearer, in front of this clearer I place a
roller for catching motes, dirt and leaf and other impurities from the clearer, this
dirt roller is set to the clearer which cards with the dirt roller and also cleans the
working roller above it; the clearer is cleaned by the main cylinder, the dirt roller
revolves slowly and is stripped by the ordinary doffing comb and the fibre is formed
into a roll or fleece which is removed by hand;-over the spaces between the
ordinary clearer rollers and the preceding working rollers I place plates or doctors
the edges of which are close to the front of the clearers and extend backward to
the preceding working rollers, these plates project a little over the working rollers;
they are adjustable to the clearer rollers; I use four or other number of these
plates for throwing off the small leaf and dirt on to the next preceding roller and
returning them to the first working roller. after having passed the said working
roller and by the clearer above the licker-in the small leaf and dirt are deposited
upon the dirt roller over the licker-in, after which they are stripped off as usual
and removed by hand; also by these plates the larger motes are returned and are
deposited amongst the licker-in flyings after the motes have been cleaned of the
fibres which usually adhere to them, more motes are fixed in the teeth of the
clearers by the use of these plates.

page_text: I place a card roller or clearer over the junction of the main cylinder and doffer,
this card roller cleans another roller placed above it which I call a skimmer; the
clearer is set to the main cylinder and is cleaned by it; the skimmer is set to the
clearer and main cylinder and is cleaned by the clearer; the skimmer runs surface
to surface and point to point of the teeth of the wire with the main cylinder; in
front of this skimmer I place also another dirt roller which is set to the skimmer
from which it receives some small dirt which has escaped the preceding rollers,
this dirt roller is above the doffer and is stripped by a doffing comb connected to a
doffing comb which strips the other dirt roller which I place higher than the
skimmer upon the main cylinder and set to the main cylinder in order to catch
small motes or other impurities which have escaped the operation of the preceding
plates and rollers, this dirt roller receives its strippings from the main cylinder;
the strippings from each of these dirt rollers are formed into a roll or fleece and
removed by hand.
I place on one of the working rollers near the doffer an eccentric which moves a
forked lever, this lever imparts a to and fro motion to my improved combination
of doffing combs for the two last named dirt rollers the doffing comb for the dirt
roller above the skimmer is fixed on hinged arms adjusted by set screws: the
dirt rollers are turned round by worms and worm wheels and other gearing.
I place a dividing plate between these two dirt rollers to keep the strippings
separate.
"I connect the two doffing combs near the doffer so as to be actuated simultaneously.
I also connect the dirt rollers near the doffer by suitable gearing. These two dirt
rollers near the doffer are of a different kind, one from the other, one takes its
strippings from the main cylinder, the other takes its strippings, which are more
free from dirt, from the skimmer; this last dirt roller is the final place of operation
for cleaning, after which the clearer takes the good fibre off the skimmer and
places the same upon the main cylinder, after which the doffer receives the finished
fibre from the main cylinder.
In front of the skimmer and below the last dirt roller, there is a receptacle
or trough for catching any light leaf, or light dirt that flies off from them.

"IMPROVEMENTS IN CARDING ENGINES."
The object of my invention is to provide improved appliances to remove leaf and
other impurities from the back or feed end of a carding engine, to clean the fibre
more efficiently at the front or delivery end of the machine, to reduce the number
of times of stripping and grinding the main cylinder and to card a larger quantity
of fibre in a given time than can be done by machines of the ordinary construction.
In performing my invention I make use of a carding engine having a main
cylinder with rollers and clearers of the ordinary construction.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying drawing which shows in section part of a
carding engine to which my improvements are applied.
My invention consists in placing a clearer roller i over the licker-in d which I
set to the main cylinder e: above this clearer i I place a working roller which is
set to the main cylinder and is cleaned by the clearer i: in front of this clearer I
place a roller k (driven by worms and worm wheels from the feed roller) for
catching motes, dirt, leaf, and other impurities from the clearer i: this dirt roller k
is set to the clearer which cards with the dirt roller and also cleans the working
roller above it: the clearer is cleaned by the main cylinder e: the dirt roller
revolves slowly and is stripped by an ordinary doffing comb m worked by
eccentrics m³ on the roller; and the strippings are formed into a roll or fleece
which is removed by hand :-over the spaces between the ordinary clearer rollers g
and the preceding working rollers fand j I place plates or doctors r the edges of
which are close to the front of the clearers and they extend backward to the.
preceding working rollers, these plates project a little over the working rollers and
they are adjustable to the clearer rollers. I use four or other number of these
plates (one or more) for throwing off the small leaf and dirt on to the next
preceding roller and returning the leaf and dirt to the first working roller j after
having passed the said working roller and by the clearer i above the licker-in d
the small leaf and dirt are deposited upon the dirt roller k over the licker-in after
which they are stripped off by the comb m and removed by hand. By these
plates the larger motes are returned and are deposited amongst the licker-in
flyings after they have been cleaned of the fibres which usually adhere to them and
a great quantity of motes are also fixed in the teeth of the clearers g and i.
The plates have slots at the ends for adjustment and they are secured to the
frame sides.
I place a card roller or clearer g³ over the junction of the main cylinder e and
doffer h this card roller cleans another roller n placed above it which I call a
skimmer, the clearer g² is set to the main cylinder and is cleaned by it: the
skimmer n is set to the clearer g₁ and main cylinder and is cleaned by the
clearer g: the skimmer n runs surface to surface and point to point of the teeth of
the wire with the main cylinder: in front of this skimmer I place a dirt roller o
which is set to the skimmer from which it receives some small dirt which has
escaped the preceding rollers: this dirt roller o is stripped by the ordinary doffing
comb p to which I connect a doffing comb på which strips another dirt roller q
which I place bigher than the skimmer upon the main cylinder and set to the
main cylinder in order to catch small motes or other impurities which have escaped

page_text: :
the operation of the preceding plates and rollers, this dirt roller q receives its
strippings from the main cylinder the strippings from each of these dirt rollers
are formed into a roll or fleece and removed by hand. A slow motion is transmitted
to the roller o from the doffer by worms and worm wheels as usual and on the
roller o is a wheel y which communicates motion to a wheel y on the shaft of the
roller q through a carrier y¹. The carrier wheel y¹. turns on an adjustable stud
held by two brackets one on each side of the wheel 3 on the shaft of which they
are suspended.
I place on one of the working rollers f near the doffer eccentrics m³. which move
side rails or forked levers p¹ that slide in brackets connected to the frame as usual,
these levers impart a to and fro' motion to my improved combination of doffing
combs for the two last named dirt rollers: the doffing comb for the dirt roller q is
fixed on binged arms p adjusted by set screws p³ fitted in brackets fixed to the
side rails p. I place a dividing plate p' between these two dirt rollers to keep
the strippings separate.
The doffing combs p and p² are connected so as to act simultaneously. The two
dirt rollers o and q are of a different kind one from the other, the roller q takes
its strippings from the main cylinder, the roller o takes its strippings, which are
more free from dirt, from the skimmer n: this last dirt roller o is the final place of
operation for cleaning after which the clearer g2 takes the good fibre off the skimmer
and places the same upon the main cylinder after which the doffer h receives the
finished fibre from the main cylinder.
In front of the skimmer and below the last dirt roller, there is a receptacle or
trought for catching any light leaf or light dirt that flies off from them.
Having stated the nature of my invention and described the manner of
performing the same
I declare that I claim
1. The combination and arrangement of the parts forming an improved carding
engine substantially as herein described and shown.
2. The plate or plates r in combination with the rollers and clearers substantially
as and for the purpose herein described and as shown.
3. The clearer g³, dirt roller q and comb p³ acting in combination with the main
cylinder e, skimunern, dirt roller o, and comb p substantially as and for the purpose
herein set forth.
In witness whereof I the said Abraham Holden have hereunto set my hand
and seal this fourth day of September One thousand eight hundred and
