Improvements in Machines for Scouring and Dyeing Textile Warps
or Yarns.
FREDERICK BARRACLOUGH, Green Lane, Yeadon, near Leeds, in the County
of Yorkshire, Woollen Manufacturer, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to produce a machine for the purpose of dyeing
and scouring textile warps and yarns in a more efficient manner, than is the case
with machines now in general use.
In carrying out my improvements I make a rectangular shaped cistern, of any
required dimensions and material, into which I fit a moveable frame, made of any
suitable material, which said frame carries an arrangement of rollers and guides,
for the purpose of carrying the warp or yarn in the dyeing or scouring operation.
The frame I fix in such a manner that I can lift it out of one cistern into another,
when occasion requires, without having to remove the warp or yarn from the rollers.
The frame I make of any dimensions required..
I fix in the frame two horizontal series of rollers in any number required, one set
being fixed transversely near the bottom, and the other set fixed transversely on
the top, the latter being geared directly to each other by toothed wheels on their
ends, and they run in bushes set in the frame. The bottom rollers run loose in
bushes set in the frame. I give motion to the top rollers either by hand or by
power as required. I fix longitudinally, in the frame at right angles to the rollers,
a required number of guides for the purpose of dividing the space into an even
number of "drafts " or "divisions," and to guide the warp or yarn being operated
upon. In dyeing or scouring the warp or yarn, I prefer to do so in "rope" form,
and I run it on to the rollers as follows:-
Commencing at the front of the frame, I pass the warp or yarn under the first
bottom roller in the outermost "draft" or "division," I then pass it up over the
second top roller, and then down under the third bottom roller, then up over the
fourth top roller, and down under the fifth bottom roller, and so on; in this course
I miss every alternate roller, both top and bottom, until the warp or yarn reaches
the reverse end of the frame from whence it started. After passing under the last
bottom roller, the warp or yarn is caused by a guide to travel across into the second
"draft" or "division on its way up to the last top roller in the frame, it then
passes over the top roller towards the front and travels to the front of the frame,"
by passing under and over the alternate rollers, which it did not touch when
travelling from front to back of the frame. On reaching the front, the warp or
yarn is again made to traverse by means of a guide, and thus enters the third
"draft" or "division," passing again from front to back of the frame, over and
under the same alternate rollers, and in the same manner, as it did in the first
"division." The warp or yarn thus travels, under and over rollers in the bottom
and top of the frame respectively from front to back, and then from back to front,
continuing this, and traversing one "draft" or "division," each time, it arrives at
either end of the series of rollers, until, finally, it arrives on the top front roller, at
the reverse side of the frame from whence it entered the frame. Before running
the warp or yarn into the cistern, which cistern contains the dye liquor or scour
liquor, I remove the frame, and then put the warp or yarn on to the frame, and
then fasten the two ends of the warp or yarn together, thus forming an endless
band of it. I then place the frame into the cistern again.
I make a trough of wood or metal in a suitable position, by fixing it either to

page_text: "
the front part of the frame or to the corresponding part of the cistern. This I
make to slope downwards across the front of the frame, from the point at which the
warp or yarn finally leaves the top roller, to the point at which it first passes
under the bottom roller. The warp or yarn is delivered into the said trough from
the top roller, and then slides down to the bottom of the trough, whence it is again
drawn round the bottom roller, and then through the series of rollers. Any spare
length of warp or yarn lies in this trough. In order to remove any curling or
shrinking of the threads of the warp or yarn, which may occur when lying "slack
in the trough, I place a short loose roller, above the second "draft" or "division"
only, at any required height, the said roller being adjustable, and the warp or yarn
is drawn over this said short loose roller. As this short additional roller is not
geared to any other roller, but only revolves in bushes in the frame, by the action
of the warp or yarn being drawn over it, there is a gentle tension upon the warp or
yarn, from the time it leaves the trough, and passes over the additional roller, and
under the third bottom roller, and up to the fourth top roller. I regulate the
tension upon the warp or yarn, either by adjusting the additional roller to a
required height, or by suitable brake power applied to it. When the warp or yarn
in the operation of dyeing or scouring passes over the front top roller for the last
time before dropping into the trough, it is occasionally liable to slip back, and in
order to prevent this, I fix a squeezing roller in the frame of such dimensions, and
in such a position, that it gears into the front roller in this "division" only. This
said roller, which I make of wood or metal "nips" the warp or yarn, and thus
prevents it slipping back, or as an alternative I fix two additional rollers, in a
horizontal plane, a suitable distance apart, and these I gear to the front roller, and
I pass the warp or yarn under one and over the other roller, before allowing it to
fall into the trough. I fix one or more rollers, above one or more of the top
rollers, the said rollers I make of wood or metal and I either run them loose in
bushes in the frame, or gear them to the top rollers, as may be required. In
scouring operations, these said rollers act as squeezing rollers, as the warp or yarn
passes over the top rollers. I fix them in the frame, in such a manner, that they
can be adjusted by means of springs or by other suitable means, in order to adapt
them to varying thicknesses of warp or yarn.

COMPLETE SPECIFICATION.
Improvements in Machines for Scouring and Dyeing Textile Warps
or Yarns.
FREDERICK BARRACLOUGH, Green Lane, Yeadon, near Leeds in the County
of Yorkshire, Woollen Manufacturer, 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:-
The object of my invention is to produce a machine for the purpose of dyeing
and scouring textile warps or yarns in a more efficient manner than is now the
case in general use, and at the same time construct the machine in such a manner
that it can be moved from one cistern to another, or can be used as a drying
frame, without the yarn having to be removed from the frame, until the said yarn
is dried.
Figure 1. shews a four-sided frame A. A. with the top and bottom rollers of
my machine, and the arrangement of the yarn D. in the first "draft"
"division" c¹ and also a cistern F. F.
"
or
Figure 2. shews frame A. A. with top and bottom rollers and the arrangement
of the yarn D. in the second "draft" or "division" c².
Figure 3. is a view of the back of the frame A. A. with the arrangement of

page_text: guides 66 67
аци
Figure 4. is a view of the front of the frame A. A. shewing trough E.
Figure 5. shews the arrangement of the guides 16 6 4 6 forming the
drafts'
or "divisions" cc cc as seen when looking into the interior of the
frame A. A. from the top of the latter.
In the frame A. A. I run a series of top and bottom rollers in any required
number. As an example I shew in my drawings a set of five rollers a a² as a as
which run loosely in bushes in the frame, and a second set of five rollers aº a
a8a alo which run in bushes in the frame, the latter set being geared directly to
each other by toothed wheels on their ends. I give motion to the rollers a a
as a al by hand or by power as required. In cases where motion is given by
hand, I fix a cranked handle to one end of the roller a this handle being turned
by hand; and in cases where motion is given by power, I put a driving pulley on
the end of the roller a and motion is then transmitted to it from a driving shaft
by a belt, or by any other suitable means.
I fix longitudinally in the frame A. A. at required positions, a number of
guides for the purpose of dividing the space inside the frame A. A.
into "drafts" or "divisions" c¹ c2 c3 c which keep the warp or yarn D. from
getting out of position on the rollers.
In dyeing and scouring the warp or yarn D. I prefer to do so in "rope" form,
and I put it upon the two sets of rollers as follows:-I pass the yarn D. under
the front bottom roller a¹ in the first "draft" or "division" c'. I then pass it up
oyer the top roller a and then down under the roller a³ then up over the roller a
and down under the roller a then by means of an additional guide which is
fixed on the back of the frame A. A. I carry the warp or yarn D. obliquely
upward to the top roller a over which I pass it into the second "draft"
"
or
"division" c². In this second "draft" or ❝ division I pass the yarn D. down
"
23
under the roller a¹ and up over the roller as then down under the roller a² and
up over the roller-a; it is then caused by an additional guide on the front of the
frame A. A. to pass obliquely down under the roller a', and then it passes up into
the third "draft
or ❝ division in a similar manner to that in which it passed
from the first into the second "draft" or "division" I then pass the yarn D.
under and over the same alternate rollers, that I did in the first "draft or
(division," and then pass it by an additional guide 67 fixed on the back of the
frame A. A. into the fourth "draft" or "division". I then pass the yarn D.
under and over the same alternate rollers that I did in the second "draft or
❝ division."
66
"
"
The warp or yarn is thus carried under and over the bottom and top rollers
alternately, from front to back, and then from back to front of the frame A. A.
traversing into the next "draft" or "division," each time it arrives at either end
of the series of rollers, until it finally arrives at the top front roller, at the reverse
side of the frame A. A. from whence it started. When the warp or yarn D. is
shorter than the capacity of the frame A. A. 1 cause it to pass over and under
a smaller number of the rollers in one or more of the "drafts"
or "divisions "
or not to enter all the "drafts or "divisions."
66
"
"
In my drawings I only shew two sets of five rollers each, and four "drafts"
or divisions," but I do not confine myself to any specified number of rollers,
"drafts" or "divisions," or of any specified dimensions, as I can increase them
according to requirements, but the "drafts or divisions" I so regulate, that,
after the warp or yarn D. has been passed through the whole of the rollers, the
two ends of the yarn D. can be brought together across the front of the frame A. A.
and fastened together, thus forming an endless "rope" of yarn D.
I make a trough E. and fix it to the front part of the frame A. A. from the
point at which the yarn D. finally leaves the top roller a to the point at which it
first passes under the bottom roller a¹. The yarn D. is delivered into the
trough E. and slides down to the bottom, whence it is again drawn under the

page_text: bottom roller a and thence through the two series of rollers, when the said rollers
are in motion, but I do not confine myself to the trough E. as a means of carrying
the yarn D. across the front of the frame A. A. After I have put the yarn D.
on to the two series of rollers as described, I fasten the two ends together I then
put the frame A. A. into a rectangular shaped cistern F. F. in which is the dye
or scour liquor, I then give motion to the rollers, in either direction, by hand or
by power, and as long as the motion is continued the yarn D. is being carried
either forward or backward through the various "drafts" or "divisions in the
frame A. A. and the dycing or scouring operation is also being continued.
.
After the dyeing or scouring operation has been carried out, I can remove the
frame A. A. out of the cistern F into another cistern, without taking the yarn off
the rollers, or I can utilise the frame A. A. with the yarn D. upon it, as a drying
frame, by removing it into a drying house, or by drying the yarn D. upon the
frame A. A. in the open air.
In my Provisional Specification, I described a roller for preventing curling
and shrinking of the warp or yarn, and also rollers for squeezing the warp or
yarn, but as these are not essential to my invention, and as I make no claim in
respect to these, I do not include them in my drawings.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
In machines for scouring and dyeing textile warps and yarns, the use of the
removeable frame, in combination with the bottom rollers, top rollers, and the
guides as described, for the purpose of carrying the warp or yarn from front to
back and from back to front of the frame, during the operation of scouring and
dyeing the warps and yarns.
