page_text: LETTERS PATENT to Arthur Barraclough, of Boys Mill, Halifax, in
the County of York, Woollen Manufacturer, for the Invention of
" AN IMPROVEMENT IN WOVEN FABRICS AND IN THE MEANS OF PRODUCING
THE SAME.
"
Sealed the 5th December 1874, and dated the 26th August 1874.
PROVISIONAL SPECIFICATION left by the said Arthur Barraclough at
the Office of the Commissioners of Patents, with his Petition, on
the 26th August 1874.
I, ARTHUR BARRACLOUGH, of Boys Mill, Halifax, in the County of
York, Woollen Manufacturer, do hereby declare the nature of the said
Invention for "AN IMPROVEMENT IN WOVEN FABRICS AND IN THE MEANS OF
PRODUCING THE SAME," to be as follows:-
-
The object of this Invention is to produce a woven fabric having the
lists either of different color or of different material from the body of
the fabric. To effect this I use separate spools of weft yarn for the two
lists, which may be either of the same colour or kind of material or may

page_text: differ in colour or material; and I use spools of yarn for the body of the
fabric which may be of a different colour or different kind of material
from either of those for the lists of the fabrics. The spools of weft yarn
to form the lists are placed on pikes in suitable position so that weft
may be drawn off as required, and the spools of weft yarn to form the
body are inserted in the shuttle so that weft may be picked or introduced
into the shed in the usual manner.
The wefts for the lists are operated by healds or harness in such
manner as either to be raised or lowered when a shoot of the body weft
yarn is made to allow it to pass under or over, and on the return shoot
of the body weft it is lowered or raised to allow the body weft to pass
on the other side of it and thus interlock the body weft with the list
weft and draw it in to the extent of the width of the list warp threads
which are operated suitably for the purpose.
The warp threads for the body of the fabric are operated at suitable
times by shafts or treddles as usual; and those of the lists are also
operated by separate shafts, healds, or heddles for each list.
SPECIFICATION in pursuance of the conditions of the Letters. Patent,
filed by the said Arthur Barraclough in the Great Seal Patent Office
on the 26th February 1875.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARTHUR
BARRACLOUGH, of Boys Mill, Halifax, in the County of York, Woollen
Manufacturer, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of August, in the year of 2
our Lord One thousand eight hundred and seventy-four; in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,..
give and grant unto me, the said Arthur Barraclough, Her special licence
that I, the said Arthur Barraclough, my executors, administrators, and
assigns; or such others as I, the said Arthur Barraclough, my executors,
administrators, and assigns, should at any time agree with, and. no.
others, from time to time and at all times thereafter. during the term
therein expressed, should and lawfully might make, use, exercise, and

page_text: vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVEMENT
IN WOVEN FABRICS AND IN THE MEANS OF PRODUCING THE SAME," upon the
condition (amongst others) that I, the said Arthur Barraclough, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Arthur Barraclough, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Shects of Drawings (that
is to say) :-
The object of this Invention is to produce woven fabrics having the lists
either of different colour or of different materials from the body of the
fabric. To effect this I use separate spools of weft yarn for the two lists,
which may be either of the same colour or kind of material or may
differ in colour or material. And I use spools of yarn for the body of the
fabric which may be of a different colour or different kind of material
from either of those for the lists of the fabric. The spools of weft yarn
to form the lists are placed on pikes in suitable position so that weft
may be drawn off as required, and the spools of weft yarn to form the
body aro inserted in the shuttle so that weft may be picked or introduced
into the shed in the usual manner.
The wefts for the lists are operated by healds or harness in such
manner as either to be raised or lowered when a shoot of the body weft
yarn is made to allow it to pass under or over, and on the return shoot
of the body weft it is lowered or raised to allow the body weft to pass
on the other side of it and thus interlock the body weft with the list
weft and draw it in to the extent of the width of the list warp threads,
which are operated suitably for the purpose.
:
The warp threads for the body of the fabric are operated at suitable
times by shafts or heddles as usual; and those of the lists are also
operated by separate shafts, healds, or leddles for each list.

page_text: In order that this invention may be any understood Inerem m
reference to three accompanying Sheets of Drawings of such parts of an
ordinary loom, say, for weaving woollen fabrics, and of such details as
are necessary to illustrate my Invention and the means of carrying out
the same.
Fig. 1 is a sectional end elevation; Fig. 2 is a plan view; and Figs. 3,
4, 5, 6, and 7 are details.
In Fig. 1 A is the body warp which passes through the eyes in the
healds A, A, in the usual manner, these healds being operated by the
treading tappets a, a¹. In Fig. 2 B and C are the warp threads for
forming the lists or selvages of the fabric; these threads pass respect-
ively through the eyes of the licalds B¹, B, and C, C, which arc
operated by the tappets b, b', and c, c¹, as shewn in Fig. 1. The arrange-
ment of these tappets is shown in Fig. 4. On comparing these tappets
with the tappets a, a', in Fig. 5 it will be seen that the "dwell" in the
tappets b, b, and c, c¹, is twice as great as the dwell in a, a; the effect
of which is that in every revolution of the tappet shaft the tappets a, a',
cach tread twice whilst the tappets b, b', and c, c', only tread once.

The weft for the body of the fabric is placed in a shuttle which is
thrown or picked in the usual manner, and the spools or cops of weft for
each of the lists are placed upon pikes D and D₁ (see Fig. 2), one at
each side of the loom. The weft from the pike D passes over the tension.
wire d and through one of the eyes in the healds A², then through tho
"reed" about two inches from the outer edge of the list. The weft from
the pike D¹ passes over the tension wire d', through one of the eyes in
the healds A', and through the reed, as described above, so that the two
wefts are raised and lowered alternately along with the body warp.
details of list, weft, pike, and tension wire sce Figs. 6 and 7.
For
The list warps B and C "shed" alternately with the body warp, when
the shuttle is in box E (Fig. 2), the body warp, and that of the list B
shed together, and when the shuttle is in the opposite box the body
warp and that of the list C shed together.
In Fig. 1 the list weft D is shown lowered and resting on the "slay
board," the last "shoot" of the body weft having passed under it, the

page_text: وق
shuttle being in the shuttle box E. It must now be supposed that since
the last "pick" the body warp and that of the list B have been changed
or shed, thus securing the body weft and the shoot of list weft which
was drawn from off the pike D'; the list warp C however has remained
open, and will be so until the next "pick," when the shuttle on leaving
box E will pass over the list weft D, the body weft drawing in and
interlocking the list weft and simultaneously withdrawing to the edge of
the body warp so much of the body weft as lay unsecured in the "shed'
formed by the list warp C, as will be seen on reference to the detail,
Fig. 3. As soon as the shuttle enters the opposite box the body warp
healds A', A³, and the list warp healds C₁, C, change or shed, and the
shoot of list weft D and body weft will thus be secured. The shuttle
after passing over the list weft D passes under the list weft D', over
which it passes on its return, thus drawing in and interlocking a "shoot"
after the manner already described in reference to the list weft D. With
cach shoot of body weft one shoot of list weft is drawn to the edge of
the body warp, but the list weft "shoot" being double, as shown in
detail (see Fig. 3), it follows that the same number of threads are
inserted in the lists as in the body of the fabric.
In weaving warps of tender yarn I protect those threads of the body
warp which are situated close to the selvage warp threads from the effects.
of the increase of tension or strain which it is necessary to put on the
body weft in order to draw in the list wefts by passing a strong cotton,
linen, or other thread G (see Fig. 1) through the heald eye belonging to
and along with the outermost body warp thread at cach side of the loom,
which cotton or other thread is woven into the fabric. The tension on
the body weft may be obtained by any of the ordinary mcans in uso for
that purpose.
Having thus described the nature of my Invention, and shewn by.
Drawings how the same may be practically carried out, I would have it
understood that I do not confine myself to the precise details of con
struction as herein shewn, but what I claim as my Invention is,--
Firstly. The production of woven fabrics having the lists either of
different colour or of different materials from the body of the fabric by
using list wefts, either of different colour or of different materials from
the weft used for forming the body of the fabric.

page_text: Secondly. The mode, herein-before described, of carrying out the same
r any mere mechanical modification of same.
In witness whereof, I, the said Arthur Barraclough, have hereunto
set my hand and seal, this Twenty-third day of February, in the
year of our Lord One thousand eight hundred and seventy-five.
