I, CHARLES RHODES of Crown Works Alfred Street, Huddersfield, Yorkshire
Woollen Spinner, do hereby declare the nature of my invention for "IMPROVEMENTS
IN MACHINERY FOR CARDING AND SCRIBBLING WOOL, COTTON, AND OTHER FIBRES
to be as follows:-
"
In this description of machinery a certain roller is employed called a "fancy."
This roller revolves in contact with the swift or cylinder and is employed for the
purpose of lifting the fibre onto the surface of the cards, so that the said fibre can
be placed onto the doffer.
In practice it is found that as this "fancy" roller revolves, it creates a current of
air, which air gathers (same as the air generated by a fan) about the middle of the
cylinder, and in doing so, a portion of the loose fibres on the surface of the cards
are drawn or forced by the current of air to the middle of the said cylinder
consequently the fibre is unequally spread, and uneven yarn is produced.
"
My Invention is intended to counteract the action of the air generated by the
velocity of the said "fancy" roller, and this I accomplish by placing in the angle
of the swift and doffer, but underneath the "fancy one or more winged rotary
bars, or a bar of any other form may be employed which I find counteracts the air
generated by the "fancy" roller, and effectually prevents the fibres from gathering
in the middle of the swift.
I also find that by checking the wind caused by the "fancy" that the small
loose bits of fibre which are seen flying about every carding machine are not now
as much observed. In some cases it may be necessary to use in conjunction with
the said winged bar a shield or cover to direct the current of air.
Although I have described the application of this winged bar as being used in
connection with the "fancy," each winged bar may be used in connection with
other rollers in carding and scribbling machinery, for the purpose of preventing
unequal distribution of the fibre.

Cotton, and other Fibres.
I, CHARLES RHODES of Crown Works Alfred Street, Huddersfield, Yorkshire
Woollen Spinner do hereby declare the nature of my invention for "IMPROVEMENTS
IN MACHINERY FOR CARDING AND SCRIBBLING WOOL, COTTON, AND OTHER FIBRES,"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
In this description of machinery a certain roller is employed called a "fancy."
This roller revolves in contact with 'the swift or cylinder and 'is employed for the
purpose of lifting the fibre onto the surface of the cards so that the said fibre can
be placed onto the doffer.
In practice it is found that as this "fancy" roller revolves it creates a current of
air, which air gathers (same as the air generated by a fan) about the middle of the
cylinder, and in doing so a portion of the loose fibres on the surface of the cards
are drawn or forced by the current of air to the middle of the said cylinder,
consequently the fibre is unequally spread and uneven yarn is produced.
"
My invention is intended to counteract the action of the air generated by the
velocity of the "fancy" roller and this I accomplish by placing in the angle of the
swift and doffer and underneath the "fancy one or more winged rotary bars, or a
bar of any other form may be employed which I find counteracts the air generated
by the "fancy" roller and effectually prevents the fibres from gathering in the
middle of the swift.
In order that my invention may be more fully understood I herein give reference
to the accompanying sheet of drawings wherein Fig. 1 is sectional elevation of so
much of a carding engine as is necessary to shew the application of my improve-
ments thereto. A is the swift, B the doffer and C the "fancy" roller all arranged
and driven in the usual way. Underneath the "fancy" roller and in the angle
formed by the doffer and swift is a bar D mounted in suitable bearings at each side
of the machine, such bar being preferably provided with wings or plates a secured
thereto. (See Fig. 2 which is end view and Fig. 3 which is longitudinal view of the
said bar on an enlarged scale.
On one end of the bar D is mounted a pulley E which receives rotary motion
from the pulley F on the shaft of the " fancy" roller. As the "fancy" roller
revolves in the direction shewn by the arrow, its velocity generates a current of
air which if not counteracted has a tendency to draw or induce the loose fibres (on
the cards of the swift A) towards the middle of such swift, consequently the fibre
is unequally spread and uneven yarn produced thereby.
By employing the winged bar D in the manner shewn, and rotating such bar in
the same direction as the "fancy" the current of air generated and gathered
midway of the swift by the said "fancy" is checked or counteracted, thus preventing
the fibre from being unequally spread whereby an even yarn is produced.

I also find that by checking or counteracting the current of air caused by the
fancy" roller that the small loose bits of fibre which are seen flying about every
carding machine are not now as much observed.

page_text: In some cases it may be necessary to use in conjunction with the said winged bar
a shield or cover to direct the current of air.
Although I have described the application of this winged bar as being used in
connection with the "fancy" roller such winged bar may be used in connection
with other rollers in carding and scribbling machinery for the purpose of preventing
unequal distribution of the fibre.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
In carding or scribbling machines for preventing unequal distribution of the
fibre, the use and employment of the rotary bar D winged or otherwise for
counteracting the current of air generated by the "fancy" or other roller substan-
tially as set forth.
