Improvements in Machines for Scouring and Dyeing Textile Warp
or other 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 :-
My invention has for its object the scouring and dyeing of yarns in a more
economical and effective manner than is generally the case, and it relates particularly
to the invention, a Patent for which was granted to me in A.D. 1892, and
numbered 22893. It can also be applied to other scouring and dyeing machines of
a similar construction, in which the yarns require to be brought across from one
side of the machine to the other, in order to re-enter the principal part of the
inachine.
In carrying out my invention I use the same style of framework, and also
the various wheels, rollers, and other parts of my invention numbered 22893,
A.D. 1892, with the exception of the trough, and in place of the trough I substitute
mechanism, by means of which the yarn is passed from one end of the top front.
roller to the opposite end of the bottom front roller, in order to complete its
circuit.
This substituted nechanism consists of two series of short horizontal rollers,
which are upon horizontal axes, set across the front of the machine-frame, at right
angles to the principal rollers of the machine, and placed at heights on the frame
corresponding to the positions of the principal top and bottom rollers.
The short rollers of the top series are put in motion by means of gearing, driven
from or by the wheel which gives motion to the principal rollers of the machine.
The short rollers of the bottom series run loose in bushes, and one or more of them
are made adjustable, by being made to slide in a framework having perpendicular
slots, so that by raising or lowering the said rollers, they may be adjusted to various
lengths of yarns.
As an alternative; instead of making the bottom series of short rollers adjustable,
I keep them fixed and place one or more removable adjustable rollers, above the
bottom series of rollers, and use them when required, or I omit the adjustable
rollers entirely. All the said rollers are flanged and are provided with guides, in
order to prevent the yarns from spreading over the ends of the rollers.
The positions of the rollers are as follows:-The first bottom short roller is
placed in front of the last draft or division of the machine of my invention
numbered 22893, A.D. 1892; the first top short roller is placed in front of the last
draft but one: the second bottom short roller is placed in front of the last draft
but two; and so on, until finally the last top short roller is placed in front of the
first draft or division.
The course of the yarn among the short rollers is as follows :—
When it leaves the top front roller of the machine in the last draft, or division,
it passes down under the first bottom short roller, then up over the first top short
roller, then down under the second bottom short roller, and so on until it passes up
over the last top short roller, whence it passes down under the front bottom roller
of the machine in the first draft or division of the same.
Instead of beginning at the first bottoin short roller, and ending at the last top
short roller, the yarn may, when shorter than the full capacity of the machine,
enter the series at any short roller, and leave it at any other short roller, provided

page_text: that it always enters and leaves the series by rollers which are respectively opposite
to the last and first drafts or divisions occupied by the yarn in question at the
time.
When desirable owing to its shortness, the yarn may miss one or more of the
intermediate short rollers at either top or bottom. The direction in which the yarn
travels, also its position on the short rollers, may be reversed when required, to
suit corresponding changes in the machine referred to
*numbered 22893 A.D. 1892.

Improvements in Machines for Scouring and Dyeing Textile Warp
or other Yarns.
FREDERICK BARRACLOUGH, of Yeadon near Leeds, in the County of York,
Woollen Manufacturer do hereby declare the nature of this invention and in what
manuer the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to machines for dyeing textile yarns in warp form, such as
that described in my Patent Specification No. 22893 of A.D: 1892.
In the accompanying drawings :
1
Fig. 1 is a front view of a machine such as that described in my Patent
Specification No. 22893 of A.D. 1892, the trough E therein described. having been
removed.
Fig. 2 is a front view of one form of my present invention, which I fix in front
of the part shown in Fig. 1.
Fig. 3 is a front view of another form of the same, showing the bottom rollers
made adjustable instead of fixed.
Fig. 4 is a front view of another form of the same, which is a combination of the
forms shown in Figs. 2 and 3.
Fig. 5 is a top view of an adjustable roller and fittings attached thereto.
Fig. 6 is a front view of the same.
This invention consists in placing certain mechanism on the front of the machine
frame, in the corresponding place to that occupied by the trough E described in
the above-mentioned Specification; the trough E being now entirely omitted.
This mechanism consists of two horizontal series of short rollers (marked d¹ d
ee upon the drawings filed herewith), which are upon horizontal axes, set across
the front part of the machine-frame A at right angles to the front principal
rollers a and a' of the original machine, and placed at heights on the frame
corresponding to the heights of the principal rollers a and a respectively.
The frame A and the rollers a and a' are shown in Fig. 1 of the accompanying
drawings, and also in the drawings filed with my Patent Specification No. 22893
of A.D. 1892.
The length of each of the short rollers in my new mechanism is sufficient for the
warp to pass round it once only, and will generally be equal to one or two times its
diameter. The diameter of the short rollers is the same as that of the other rollers
in the machine.
The distance of the short rollers d' d² e¹ e² in front of the principal rollers a® a¹ is
made as small as circumstances will permit.
The short rollers of the top series (d' d) are put in motion by means of bevel
gearing driven from a toothed wheel on the end of the front principal top roller of
the machine. The short rollers of the bottom series (e¹²) are not geared, but run
loose and revolve freely as the yarn (in warp form) is drawn round them. These

page_text: bottom short rollers (e² e³) may all be fixed immovably at the same height on the
frame as the bottom principal roller a', as shown in Fig. 2 of the drawings; but 1
find it more advantageous to make one or more of them adjustable by making them
to slide in a framework having perpendicular slots F' F' (Fig. 3); so that by
raising or lowering the rollers, they may be adjusted to various lengths of the
warp D, to prevent it being undesirably slack or tight. The adjustable rollers are
held at various heights in the slots as required from time to time, by means of
thumb-screws (f. Fig. 5) on the ends of the spindles on which the rollers revolve.
It is evident that instead of making the bottom rollers el adjustable, the same
object may be attained by keeping them fixed and adding an adjustable roller above
one or more of them. I show such an arrangement in Fig. 4 of the drawings. In
this case I cause the yarn (always in warp form) to pass round either the fixed or
the adjustable roller, according as it is found more suitable in dealing with each
individual length of warp. But prefer to make the bottom rollers themselves
adjustable as already described and shown in Fig. 3.
Each of the short rollers, whether top or bottom, fixed or adjustable, is preferably
Hanged to prevent the warp spreading over its ends.
These.
Just below the top short rollers dd, and just within the flanges of the same,,
are placed two guides, one of which is shown at G' in Figs. 2, 3, and 4.
guides assist to prevent the warp spreading over the ends of the rollers.
When the bottom rollers are not adjustable in height, two similar guides (one of
which is shown at G2 in Figs. 2 and 4) are placed just above them in corresponding
positions and for a similar purpose.
Close above each of the bottom rollers e¹ e² is placed a guard H H (Figs. 2
and 4) parallel with the axis of the roller, and of a breadth not quite equal to the
diameter of the roller. The object of this guard is to keep separate the two parts
of the warp which are at opposite sides of the roller, and also to prevent any slack
threads catching and wrapping round the roller. Each adjustable roller is provided
with its own independent guides and a guard, as shown in Figs. 5 and 6, and to be
hereinafter more fully explained.
The positions of the short rollers relatively to the drafts or divisions of the machine
described in my Patent Specification No. 22893 of A.D. 1892 (or to the corre-
sponding parts of a similar machine) are as follows:-The first bottom roller e¹ is
placed in front of the last draft c; the first top roller d' is placed in front of the
last draft but one, c³; the second bottom roller e' is placed in front of the last draft
but two, c; and the second top roller is placed in front of the last draft but
three (that is, in this case, the first draft.), c.
In the case of a machine with a larger number of drafts or divisions, the number
of rollers is increased in proportion, and their arrangement is a continuation of that
described above.
The course of the yarn, among the short rollers is as follows:-
When it leaves the top front roller a of the original machine, in the last draft or
division of the same, it passes obliquely forward and downward under the first
bottom short roller e', then up over the first top roller d', then down under the
second bottom roller e, then up over the second top roller d², whence it passes
obliquely backward (that is, toward the back of the machine) and downward under
the front bottom roller a' of the original machine, in the first draft or division c¹ of
It then passes through the original part of the machine in the manner
described in my Specification No. 22893 of A.D. 1892, already referred to.
When a larger number of rollers is used, the arrangement of the warp upon them
is continued alternately under and over the bottom and top rollers respectively in
the same manner as upon the rollers e¹ d¹e³ ³.
the same.
(The foregoing description of the course of the warp assumes the arrangement of
rollers shown in Fig. 2; and it sufficiently indicates its course in the arrangements
shown in Figs. 3 and 4.)
-Instead of beginning at the first bottom short roller and ending at the last top
short roller, the warp may-when shorter than the full capacity of the machine-

page_text: enter the series at any bottom roller and leave it at any top roller; provided that it
always enters and leaves the series by rollers which are respectively opposite
to the last and first drafts or divisions occupied by the warp in question at the
time.
When desirable on account of its shortness, the warp of yarn may miss one or
more of the intermediate short rollers at either top or bottom.
It is desirable that the first bottom roller round which the warp passes, should
(when adjustable) be adjusted as low in its slot as possible, in order to avoid
too sharp an angle in the course of the warp to it from the front top main
roller a
The length of the warp is limited by the size of the machine, as no part of the
warp is allowed to lie on the bottom of the dyeing cistern or to hang loosely below
any of the bottom rollers.
The following is an additional explanation of the drawings filed herewith:-
In all cases corresponding parts are distinguished by corresponding letters.
Fig. 1 shows the front part of the original machine, with the trough removed in
accordance with my present invention. A is the frame, is the front top roller,
a is the front bottom roller, are the guides placed to form the
"drafts" cc cc, and the double oblique line (without a distinguishing letter)
represents the "additional guide" on the front of the machine; all these being
shown or described in my Patent Specification No. 22893 of A.D. 1892.
The toothed wheel, shown on the end of the spindle of the top roller, transmits
motion by means of carrier-wheels to the corresponding wheel shown in Figs. 2, 3,
and 4, which causes the top short rollers to revolve at an equal speed by means of
a shaft and bevel wheels as shown in the said figures.
But I do not confine myself to this particular method of driving the top short
rollers ; nor do I make any claim for it.
Fig. 2 shows my present invention in its simplest form. The dotted line D shows
the course of the yarn (in the form of a warp) among the top and bottom rollers e¹ d¹
ed, as already described.
Figs. 3 and 4 require no further explanation than they have already received.
Figs. 5 and 6 show one of the adjustable rollers with its fittings, as seen from
above and from the front respectively. D (Fig. 6) shows the course of the warp
round the flanged roller g; and H is the guard above the roller to prevent entangle-
ment between the opposite sides of the warp. 11 and are the guides which

But I do not confine myself to this particular form of adjustable roller shown in
Figs. 5 and 6; neither do I make any claim for the form shown in the said
figures.
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 combination with such a machine as that described and shown in my Patent
Specification No. 22893 of A.D. 1892 :-
