in the County of Leicester. "AN IMPROVED METHOD OR PROCESS OF
APPARATUS FOR DRAWING AND TWISTING WOOL, COTTON, SILK, AND OTHER FIBROUS
MATERIALS,"
AND
My Invention relates to a novel method or process of drawing and twisting the
sliver of wool, cotton, silk, and other fibrous materials preparatory to the spinning
of the same.
The said Invention consists chiefly in imparting to the sliver as it passes from
the rollers of a carding or other machine to the balling head temporary or false
twists in opposite directions, that is to say, the sliver is twisted first in one and
then in the other direction during the drawing and slubbing of the same, and is
untwisted or untwists itself when taken from the ball for roving and spinning.
By this temporary or false twisting of the sliver the fibres of the same will be kept
from dividing or separating, and will be compactly and closely held together and
laid on the spool, thus obviating the difficulty ordinarily arising from adhesion
of the fibres to the ball, whereby the drawing or slubbing becomes torn and ragged.
and imperfections and irregularities are produced in the yarn,

page_text: For the purpose of this Invention I give to the tweedler conductor or guide
through which the sliver passes from the carding, combing, drawing, or other
machine, a rotary motion continued for the desired number of revolutions alter-
nately in opposite directions. This alternate rotary motion may be produced by a
belt and pulleys or gear wheels or other apparatus provided with suitable reversing
mechanism, preferably attached to and operated by the carding or other machine.
The balling apparatus is so arranged that each portion of the sliver as it is
twisted in one direction is wound on the spool or ball, so that it is held thereon
and kept from untwisting when the motion is reversed to twist in the opposite
direction. But as above specified the temporary twist thus imparted to the sliver
is removed, that is to say, it works out or is taken out of the sliver as the same
leaves the ball, and the sliver will be in the ordinary open condition as it passes
forward to the next operation.

the said William Thomas Thompson in the Great Seal Patent Office on the
27th November 1878.

My Invention relates to a novel method or process of drawing and twisting the
sliver of wool, cotton, silk, and other fibrous materials preparatory to the spinning
of the same.
The said Invention consists chiefly in imparting to the sliver as it passes from
the rollers of a carding or other machine to the balling head a temporary or false
twist produced by twisting the sliver alternately in opposite directions, that is to
say, the sliver is twisted first in one and then in the other direction during the
drawing of the same, and is untwisted or untwists itself when taken from the ball
previous to roving and spinning. By this temporary or false twisting of the
sliver the fibres of the same will be kept from separating, and will be compactly.
and closely held together and laid on the spools, thus obviating the difficulty
experienced in the ordinary method of working from the adhesion of the fibres to
the ball, whereby the drawing or sliver becomes torn and ragged, and imperfections
and irregularities are produced in the yarn.
For the purpose of this Invention I give to the tweedler conductor or guide.
through which the sliver passes from the carding, combing, drawing, or other.

page_text: machine a rotary motion continued for the desired number of revolutions alternately
in opposite directions. This alternate rotary motion may be produced by a belt
and pulleys or gear wheels or other apparatus provided with suitable reversing
mechanism preferably attached to and operated by the carding or other machine.
The balling apparatus is so arranged that each portion of the sliver as it is
twisted in one direction is wound on the spool or ball, so that it is held thereon
and kept from untwisting when the motion is reversed to twist in the opposite
direction. But as above specified this temporary twist thus imparted to the sliver
is removed, that is to say, it works out or is taken out of the sliver as the same
leaves the ball, and the sliver will be in the ordinary open condition as it passes
forward to the next operation.
In the accompanying Drawings I have shewn apparatus which has been especially
devised for carrying the said Invention into practice.
Figure 1 is a plan shewing the said apparatus arranged in combination with the
balling head and drawing rollers; Figure 2 is a front elevation, and Figure 3 is an
end elevation of the same; Figure is a front elevation, and Figure 5 a side
elevation of a portion of the said apparatus detached, and drawn to an enlarged
scale.
Like letters indicate the same parts throughout the Drawings.
A is part of the frame of the machine, to which the said apparatus is applied.
a is the tweedler conductor or trumpet, through which the sliver passes, and which
is alternately rotated in opposite directions, as above set forth. This tweedler or
trumpet has a guide or mouth-piece b with an elongated hole 6¹ for the passage of
the sliver, as clearly shewn in Figure 4.
The mechanism for imparting this alternate rotary motion to the said tweedler
or conductor a, as shewn, consists of a crank disc c, to whose pin or stud c¹ is con-
nected one end of a strap or band d, which passes under the guide pulley e, over
the guide pulley e¹, and over the pulley f on the shaft g, and over the guide
pulley h to the weight i, which is suspended on the said strap or band, and tends
always to keep the same taut on the said pulleys.
The aforesaid shaft g, which carries the pulley f, also carries a toothed wheel j,
which gears with the wheel k on the said tweedler or trumpet a
The crank disc c is fixed on the end of one of the shafts of the machine, and
thereby has a rotary motion around the axis of the said shaft.
It will be obvious that the rotation of this crank or crank disc c on its axis will
produce an alternate or to-and-fro motion of the said strap or band, which will be
pulled in one direction by the said crank, and in the opposite direction by the
weight. This alternate or to-and-fro motion of the band will impart a similar
motion to the pulley f, and through this pulley and the shaft g to the toothed
wheel on the said shaft. This wheel ; will impart a like movement to the wheel k
on the tweedler, but the said wheel k being considerably smaller in diameter than
the wheel will turn a greater number of times than the latter alternately in both
directions, thus giving the false or temporary twist to the sliver, as above
specified.
The weight is for convenience enclosed in a case or cover i¹, which may be
arranged in any convenient position.
The construction and arrangement of the various parts of the above-described
apparatus may be as shewn in the Drawings, or may be modified or varied to suit
the circumstances of each particular case in which my Invention is employed.
Having thus fully described the said Invention, and the manner of performing
the same, I wish it understood that I claim,
First. The improved method or process of manufacture, wherein the sliver of
wool, cotton, silk, or other fibrous material has imparted to it a false or temporary
twist before balling, and is untwisted as it is taken from the ball for roving and
spinning, as and for the purposes specified.
Second. The apparatus for giving the false or temporary twist to the sliver,

page_text: consisting of the parts shewn in the accompanying Drawing, or substantially
similar parts combined and operating as above set forth.
In witness whereof, I, the said William Thomas Thompson, have hereunto set
my hand and seal, this Twenty-fifth day of November, in the year of our
Lord One thousand eight hundred and seventy-eight.
WILLIAM THOMAS THOMPSON. (LS.)
