page_text: We, PLATT BROTHERS AND COMPANY, LIMITED, of Hartford Works, Oldham,
in the County of Lancaster, Machinists, do hereby declare the nature of this
invention to be as follows:-
Carding-engines as heretofore made with one doffing-cylinder, possess the
disadvantage that the main cylinder or drum is more or less rapidly filled up,
according to the nature of the material to be carded, with dirt and fibrous
material. This is due to the fact that a part of the fibrous material fed to the
carding-engine becomes lodged at the root of the card-teeth and cannot be com-
pletely transferred by the fancy roller or flyer to the points of the card-teeth.
This portion therefore remains for the most part in the main cylinder or drum,
and a frequent cleaning or stripping of the card-clothing is rendered necessary
in order to maintain the carding-engine in operation. If the fancy roller or
flyer is not capable of removing large quantities of fibrous material from the
main cylinder or drum, the output of the machine is kept low both as regards
quantity and quality, for, as soon as more fibrous material is supplied to the
carding-engine than it can efficiently deal with, a part of the said material
becomes lodged in the card-clothing, which part is again led back by the main
cylinder or drum so that the now soiled and overfilled cylinder or drum works
worse both as regards quantity and quality and finally a moment may arrive
when the machine entirely breaks down.
The object of this invention is to increase the quantitative and qualitative
output of carding-engines with one doffing-cylinder by employing two or more
fancy rollers or flyers which, in their action, assist both with respect to the
drawing out of the deep-seated fibres, as well as with respect to the arrangement
of the fibres parallel to each other.
In a carding-engine having the said invention applied thereto, the operation
preferably takes place as follows:-
From the spreading or feeding table, the fleece or fibrous material is fed by
the feed-rollers and the usual licker-in to the main cylinder or drum, on which
the fibrous material is worked by the interaction of several pairs of worker and
clearer rollers. The fibrous material heretofore has been raised by only one
fancy roller or flyer, seized by the doffing cylinder, and removed by the stripper.
For raising the fibrous material lodging in the card-clothing, on to the points
of the card-teeth and also for laying the fibres in the same direction, according

page_text: to this invention, two or more fancy rollers or flyers are employed, which, as is
known, are provided with longer teeth than those of the main cylinder or drum
and rotate more rapidly than the latter. These two fancy rollers or flyers assist
each other in their action in such a manner that the second roller raises the
material which is not raised by the first or if this is only partly effected by the
first roller, it assists or completes the work thereof.
In employing these fancy rollers or flyers on existing card-engines, either a
pair of worker and clearer rollers are dispensed with or the said rollers are
moved nearer to each other and to the spreading or feeding table; in making
new carding-engines, either the worker and clearer rollers are arranged near
together, or the sizes of the main cylinder or drum, doffing-cylinder and worker
rollers are made of suitable dimensions to enable a suitable number of pairs of
worker rollers to be employed.

An Improved Carding-engine.
We, PLATT BROTHERS AND COMPANY, LIMITED, of Hartford Works, Oldham,
in the County of Lancaster, Machinists, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Carding-engines as heretofore made with one doffing-cylinder, possess the
disadvantage that the main cylinder or drum is more or less rapidly filled up,
according to the nature of the material to be carded, with dirt and fibrous
material. This is due to the fact that a part of the fibrous material fed to the
carding-engine becomes lodged at the root of the card-teeth of the main cylinder,
and cannot be completely transferred by the fancy roller or flyer to the points
of the said card teeth. This portion therefore remains for the most part in the
card-clothing of the main-cylinder or drum, and a frequent cleaning or stripping
of such card-clothing is rendered necessary in order to maintain the carding-
engine in proper operation. If the fancy-roller or flyer is not capable of raising
to the points or surface of the card-surface of the main-cylinder or drum
large quantities of fibrous material, the output of the machine is kept low
both as regards quantity and quality, for, as soon as more fibrous material is
supplied to the carding-engine than it can efficiently deal with, a part of the
said material becomes lodged in the card-clothing, which part is again led back
by the main-cylinder or drum so that the now soiled and overfilled cylinder or
drum works worse both as regards quantity and quality and finally a moment
may arrive when the machine entirely fails to work.
The object of this invention is to increase the quantitative and qualitative
out-put of carding-engines with one doffing cylinder by employing two or
more fancy-rollers or flyers, which, in their action assist both with respect
to the drawing out of the deep seated fibres, as well as with respect to the
arrangement of the fibres parallel to each other.
In a carding-engine having the said invention applied thereto, the operation
preferably takes place as follows;
From the spreading or feeding table, the fleece or fibrous material is fed by
the feed-rollers and the usual licker-in to the main-cylinder or drum, on which

page_text: the fibrous material is worked by the interaction of several pairs of worker
and clearer-rollers. The fibrous material heretofore has been raised by only
one fancy-roller or flyer, seized by the doffing cylinder and removed by the
stripper or doffing comb. For raising the fibrous material lodging in the card-
clothing on to the points of the card-teeth and also for laying the fibres in the
same direction, according to this invention, two or more fancy-rollers or flyers are
employed, which, like the single fancy-rollers or flyers hitherto employed are pro-
vided with longer teeth than those of the main-cylinder or drum and rotate more
rapidly than the latter. These two fancy-rollers or flyers assist each other in
their action in such a manner that the second roller raises the material which is
not raised by the first or if the raising is only partly effected by the first fancy-
roller or flyer it assists or completes the work thereof.
In employing these fancy-rollers or flyers on existing carding-engines, either
a pair of worker and clearer-rollers is dispensed with or the said rollers are
moved nearer to each other and nearer to the spreading or feeding table; in
making new carding-engines, either the worker and clearer-rollers are arranged
nearer together, or the sizes of the main-cylinder or drum, doffing cylinder
and worker-rollers are made of suitable dimensions to enable a suitable number
of pairs of worker and clearer-rollers to be employed.
In the accompanying drawing, a carding-engine provided with two fancy-
rollers or flyers in accordance with this invention is shown diagrammatically
but sufficiently for the illustration of the invention. Although only one side
of the carding-engine is shown in the accompanying drawing it will be obvious
that there is at each side of the carding-engine a side-frame, a fixed bend and a
pedestal or bracket or other support for each of the working parts which extends
across the carding-engine.
In the said drawing ab are the two fancy-rollers or flyers which are employed
according to this invention and are placed between the doffer c and the worker-
roller nearest thereto. The fancy-roller or flyer b is mounted in pedestals e
secured upon the fixed bends f of the carding-engine and the other fancy-roller
or flyer a is mounted in brackets g secured to the said fixed bends f. The fancy-
rollers or flyers ab are respectively provided with pulleys hi around which is passed
the usual belt j ordinarily employed to drive the clearer-rollers k used with
the worker-rollers d of the carding-engine.
The said belt j is passed around a pulley m indicated only by dotted lines and
fast upon the axle of the main-cylinder or drum n and is passed therefrom
around the pulley h and over the several pulleys o of the clearer-rollers k, then
around a guide-pulley » similar to that ordinarily employed and around the
pulley and so back to the pulley m upon the axle of the main-cylinder or
drum n.
The directions in which the main-cylinder or drum n, the worker-
rollers d, the clearer rollers k, the fancy-rollers or flyers a b and the doffer-
cylinder revolve are clearly indicated by the arrows marked upon the drawing.
Like the fancy-roller ordinarily employed in a "roller and clearer" carding-
engine each of the fancy-rollers or flyers a b is provided with a card-wire-
covering having longer wires or teeth than those of the card-wire-covering of
the main-cylinder n and made to revolve with a surface-speed somewhat greater
than the surface-speed of the main-cylinder or drum n and preferably as is shown
in the accompanying drawing the fancy-roller or flyer b is made to revolve with
a surface-speed somewhat greater than that of the fancy-roller or flyer a. In
the working of the carding-engine the two fancy-rollers or flyers a beach take
part in raising the material operated upon to the surface of the card-clothing
upon the main-cylinder » and also aid in laving the fibres of such material
straight upon the surface of the main-cylinder n and facilitate the transfer of
the said material to the doffer c. In conjunction with the fancy-rollers or
flyers a bindicated in the accompanying drawing there are employed stripping
rollers q r s similar to the stripping rollers employed in some cases with the
single fancy-rollers or flyers hitherto employed in "roller and clearer" carding-

page_text: engines and the directions in which the said stripping rollers revolve are in-
dicated by arrows. The stripping rollers q r s are mounted in brackets secured
upon the fixed bends f of the carding-engine and the stripping roller r which
receives motion by means of a belt t from a pulley fast upon the axle of the
main-cylinder n acts upon both of the fancy-rollers or flyers a b while the
stripping rollers qs which receive motion by belts u v respectively from pulleys
mounted fast upon the axle of the stripping roller r, act upon the fancy-rollers
or flyers b respectively but the said stripping rollers may be supported and
arranged to receive motion in any other suitable manner, and instead of one
stripping roller being arranged to act upon two fancy-rollers or flyers there may
be two stripping rollers for each fancy-roller or flyer or one or more or all of
such stripping rollers may be dispensed with as may be considered preferable.
It is obvious that the two or more fancy-rollers or flyers employed according
to this invention may be supported and made to receive motion in any other
suitable manner instead of in the manner illustrated in the accompanying draw-
ing. In the application of three or more fancy-rollers or flyers in a carding-
engine according to this invention either fewer worker-rollers and clearer-rollers
may be employed or the pairs of worker-rollers and clearer-rollers
which are employed may be placed as close together as may be requisite in
order to enable the desired number of fancy-rollers or flyers to be placed between
the doffer and the worker-roller nearest thereto and to enable the requisite
number of clearer-rollers and worker-rollers to be employed or the fancy-rollers
or flyers may be themselves made of suitable size to enable the desired number to
be placed in the space available between the doffer and the worker-roller nearest
thereto in the carding-engine in which they are to be employed. In the appli-
cation of two or more fancy-rollers or flyers according to this invention to a
carding-engine the relative sizes of the fancy-rollers or flyers and the kinds of
card-wire-clothing upon the fancy-rollers or Hyers employed may be arranged as
may be considered preferable. Thus, for instance, one fancy-roller or flyer may
be furnished with card-wire of a stiffer character so as to act more like a
comb than the other or another and the other or another of the fancy-rollers
or flyers may be furnished with a more flexible wire-covering so as to act more
like a brush than the other or others.
This invention is applicable to any carding-engine in which in conjunction
with a main-cylinder from which the material operated upon is transferred to
a single doffer-cylinder, there are employed worker-rollers and clearer-rollers
whether there be one main cylinder or drum in such carding-engine or two or
more cylinders arranged to act successively upon the material which is to be
carded.
The application of this invention to a carding-engine enables a higher speed of
working and better and cleaner carding to be obtained than is possible with the
use of a single fancy-roller or flyer as hitherto employed, and also enables a
carding-engine to work longer without the main-cylinder needing to be stripped
than a carding-engine working under similar conditions but with only one
fancy-roller or flyer.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. A carding-engine with the or each cylinder of which there are employed,
besides worker-rollers and clearer-rollers and a stripper or doffer, two or more
fancy-rollers or flyers placed between the said stripper or doffer and the worker-
roller nearest thereto and operating for the purposes and substantially in the
manner herein before described.
2. In a carding-engine the combination with a cylinder or each of two or
more cylinders and worker-rollers and clearer-rollers and a stripper or doffer

page_text: used therewith of two or more fancy-rollers or flyers placed between the said
stripper or doffer and the worker-roller nearest thereto and operating for the
purposes and substantially in the manner herein before described.
Dated this Fourteenth day of September 1900.
