Improvements in or applicable to Machines for Carding Woollen
and other similar Fibres.
We JOHN LEWIS BYROM and BENJAMIN FRANKLIN BYROM, trading under
the name of Robert Byrom, Woollen Manufacturers, and JOSEPH TINKER,
Carder, all of Slackcote Mills, Delph, in the County of York, do hereby
declare the nature of this invention to be as follows:-
دو
This invention relates to machines used for carding woollen and other similar
fibres and especially to apparatus to be used therein for applying "napps or
nopps" to the sliver of wool in the carding engine in order to impart an
additional color or mixed colors to the rovings and finally to the yarn, and our
improved apparatus is especially adapted for the manufacture of knicker yarns and
the like.
Hitherto "napps" or "nopps" have usually been spread carefully (after being
weighed) upon a travelling lattice arrauged above the condenser and carding engine
and delivering them to the cylinder at a convenient part thereof and consequently
the " napps or "nopps" became somewhat worked or carded by the cylinder before
being taken off by the doffer; some of the "napps or "nopps" also were not taken
off by the doffer if they were on that part of the sliver or fleecé corresponding
with the spaces between the rings of card teeth on the doffer. These were carried
back by the cylinder and practically wasted. Furthermore some of the "napps
or "nopps" at the edges of the card cylinder were unavoidably mixed with the waste
threads, and again wasted, and such waste is a consideration, the napps or nopps being
expensive in proportion to the wool of sliver.
"
According to our invention we apply the nopps or napps directly to the doffer so
that it never reaches the sliver or fleece upon the cylinder but is applied to each
separated sliver upon the doffer.
For this purpose we fix just above the doffer a hopper into which the napps or
nopps are placed consisting of an inclined plate at the bottom of which is a small
roller covered with emery or sand or otherwise roughened or fluted.
This
small roller revolves close to a larger card covered roller forming the second
side of the hopper, suitable end plates being fixed to the above named inclined
plate.
Another small roller with blades or their equivalent is arranged above the small
roughened roller and so close to the card covered roller as to clear off superfluous
napps or nopps.
The card covered roller is provided with rings of teeth corresponding with but
narrower than the rings of teeth, upon the doffer and at each end the said roller is
covered by a ring or strip of leather or is otherwise so enlarged. that no napps or
nopps will be carried beyond the clearing roller.
At the other side of the card covered roller is a stripping roller which takes the
napps or nopps froin the card covered roller and delivers them on to the doffer; by
these means the napps or nopps are only supplied exactly in the central part of
each sliver.
The apparatus is driven by suitable gearing which can be put into or out of motion
at any time as required.

page_text: It will be seen that by the use of this apparatus no waste can occur by
"napping" or "nopping" the waste threads, or by napping or nopping the sliver
upon the card cylinder, the napping or nopping of the threads will be more regular,
and the napps or nopps not having been carded will be rounder than before. Also
the apparatus employed is much lighter and less cumbrous than when a lattice is
used; and no weighing or spreading upon the lattice is necessary, and thus
labor is economised.

Improvements in or applicable to Machines for Carding Woollen
and other similar Fibres.
We JOHN LEWIS BYROM, and BENJAMIN FRANKLIN BYROM, trading under
the name of Robert Byrom, Woollen Manufacturers, and JOSEPH TINKER,
Carder, all of Slackcote Mills, Delph, in the County of York, do hereby
declare the nature of this invention and in what manner the same is to he
performed to be particularly described and ascertained in and by the following
statement :-

"
This invention relates to machines used for carding woollen and other similar
fibres and especially to apparatus to be used therein for applying "napps
"nopps
to the slivers of wool in the carding engine in order to impart an
additional color or mixed colors to the rovings and finally to the yarn, and our
improved apparatus is especially adapted for the manufacture of kuicker yarns
and the like.
Hitherto "napps" or "nopps" have usually been spread carefully (after being
weighed) upon a travelling lattice arranged above the condenser and carding
engine and delivering them to the cylinder at a convenient part thereof and
consequently the "napps" or "nopps" became somewhat worked or carded by the
cylinder before being taken off by the doffer; some of the "napps" or "nopps
also were not taken off by the doffer if they were on that part of the sliver or
fleece corresponding with the spaces between the rings of card teeth on the doffer.
These were carried back by the cylinder and practically wasted. Furthermore
some of the "napps" or "nopps" at the edges of the card cylinder were
. unavoidably mixed with the waste threads, and again wasted, and such waste is a
consideration, the napps or "nopps" being expensive in proportion to the wool
or sliver.
According to our invention we apply the napps or nopps directly to the doffer so
that it never reaches the sliver or fleece upon the cylinder but is applied to each
separated sliver upon the doffer.
Our invention will be readily understood from the following description on
reference to the accompanying drawings illustrative thereof.
Figs. 1 and 2 shew sectional elevations of two slightly different ways in which our
invention may be carried into practical effect, and Fig. 3 is a side elevation of the
mechanism shewn on Fig. 2, shewing also part of the condenser.
Fig. 4 is a front view of one end of the doffer and the roller 62 hereafter
described.
We fix just above the doffer a, a hopper into which the napps or nopps are
placed the said hopper consisting of an inclined plate b at the bottom of which is
a small roller b1 covered with enery or sand or otherwise roughened or fluted.

page_text: This small roller b1 revolves close to a larger card covered roller b 2 forming the
second side of the hopper, suitable end plates 63 being fixed to the above named
inclined plate b.
Another small roller b4 with blades, see Fig. 1 (or its equivalent) is arranged
above the small roughened roller b 1 and so close to the card covered roller b 2 as
to clear off superfluous napps or nopps; or instead of this roller 64 we prefer to
use a vibrating comb 6* to clear off superfluous napps, as seen on Figs. 2 and 3 this
comb being driven by a lever and connecting rod x 1, shewn at Fig. 3, connected
to a crank on the shaft of one of the clearer rollers..
The card covered roller 62 is provided with rings of teeth corresponding with
but narrower than the usual rings of teeth upon the doffer a see Fig. 4, and at
each end the said roller 62 is covered by a ring or strip of leather 6** or is other-
wise so enlarged or made that no napps or nopps will be carried beyond the
clearing roller b4, or its equivalent 6*. We prefer also to mount a roller b5
immediately beyond the roller b4 or the comb 6x to gently press the napps or nopps
upon the card teeth to keep them from accidentally falling therefrom say into the
spaces between the rings of teeth.
At the other side of the card covered roller 62 is a stripping roller c which takes
the napps or nopps from the card covered roller 62 and delivers them on to the
doffer a; by these means the napps or nopps are only supplied exactly in the central
part of each sliver.
The apparatus is driven by suitable gearing (say a chain d and wheel d 1) which
can be put into or out of action at any time as required.
It will be seen that by the use of this apparatus no waste can occur by
"napping" or "nopping" the waste threads, or by napping or nopping the sliver
upon the card cylinder; the napping or nopping of the threads will be more
regular, and the napps or nopps not having been carded will be rounder than
before. Also the apparatus employed is much lighter and less cumbrous than when
a lattice is used; and no weighing or spreading upon the lattice is necessary, and
thus labor is economized.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ::
Apparatus constructed and applied substantially as hereinbefore described
for supplying "napps" or "nopps "of yarn directly to the doffer of a condenser
engine.
