IMPROVEMENTS IN WEAVING PILE FABRICS
Year: 1884

page_text: I, ABRAHAM ROTHWELL of Heywood Street Bury in the County of Lancaster
Mill Manager do hereby declare the nature of my invention for IMPROVEMENTS IN
WEAVING PILE FABRICS to be as follows :—
These Improvements relate to pile fabrics and have for their object the production
of a curled or cockled appearance on the cut face of the fabric.
The accompanying sheet of Diagrams will illustrate the manner in which I carry
out my Invention.
Figs 1 to 7 inclusive illustrate how the curled or cockled appearance may be
produced. This appearance has hitherto been obtained from the back threads only;
by my Improvements I am enabled to obtain such a face by placing the float
threads which are to form the face in an irregular manner and to use any back or
binder threads in breaking up the regularity of the back in order to assist in
breaking up the regularity of the face if desired.
In all cords hitherto made the floating has been regular either in twos or threes
but I use an irregular floating varying from one to six or more floats between each
binder or back thread. I may also use two or more different counts of weft as
hereinafter set forth.
In Fig 1, Nos 1, 5, 9, 12 14 and 16 are binders or back threads and Nos 2, 3, 4
6, 7, 8, 10, 11 13 and 15 are floats:
In fig 3 Nos 1, 6, 9 and 11 are binders and Nos 2, 3, 4 5, 7, 8 10 and 12 are
floats.
In fig 5 Nos 1, 6, 8 and 10 are binders and Nos 2, 3, 4 5 7, 9, 11 and 12 are
floats.
- In fig 7, Nos 1, 3, 6 11 18 23 and 26, are binders and Nos 2, 4, 5 7, 8, 9, 10,
12, 13 14, 15, 16 17, 19, 20 21, 22, 24, 25, and 27 are floats.
Fig 2 is the same as Fig 1 but condensed, Fig 4 is the same as Fig 3 condensed
and Fig 6 is the same as Fig: 5 condensed.
Two or more shuttles may be employed in weaving piled fabrics under my
Improvements, the shuttles having wefts of same or of different counts one or more
being used for the binders and one or more for the face or float. When two counts
of weft are used for the face a certain number of picks of fine weft may be
alternated with a certain number of picks of coarse weft for the purpose of
producing an irregular or diamond face. The two different counts of weft may
be used for the back for the same purpose.
Dated this tenth day of January 1884.

I ABRAHAM ROTHWELL of Heywood Street Bury in the County of Lancaster
Mill Manager do hereby declare the nature of my invention for IMPROVEMENTS IN
WEAVING PILE FABRICS, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:―
These Improvements relate to pile fabrics and have for their object the production
of a curled or cocked appearance on the cut face of the fabric.
Hitherto a curled or cocked appearance has been obtained from the back threads
only and my Improvements consist in the production of that appearance by placing
the float threads which are to form the face of the cloth in an irregular manner
and in using any back or binder threads in breaking up the regularity of the back
in order to assist in breaking up the regularity of the face if desired. Instead of
floating in twos or threes in the usual manner I use an irregular floating varying
from one to six or more floats between each binder or back thread. I may also use
two or more counts of weft as hereinafter set forth.
And in order that my Invention may be more readily understood I have
hereunto appended a sheet of diagrams reference being hereinafter had thereto.
•
In Fig 1 of the accompanying diagrams No 1, 5, 9, 12 14 and 16 are binders or
back threads and N° 2, 3, 4, 6, 7, 8, 10, 11, 13, and 15 are floats.
Fig 2 is the same as Fig 1 but condensed.
Fig 3, No 1, 6, 9, and 11 are binders and Nos 2, 3 4, 5, 7 8, 10 and 12 are 'floats.
Fig 4 is the same as Fig 3 but condensed.
Fig 5 N° 1, 6, 8 and 10 are binders and N° 2, 3, 4, 5, 7, 9 11 and 12 are floats.
Fig 6 is the same as Fig 5 but condensed.
Fig 7 N° 1, 3, 6, 11, 18, 23 and 26 are binders and N° 2, 4, 5, 7 8, 9, 10 12 13,
14, 15 16 17 19, 20, 21, 22, 24, 25, and 27 are floats.
The examples given are typical of the various combinations which I may
employ.
Piled fabrics made according to my Improvements may be woven in the ordinary
manner with one shuttle or they may be woven with two or more shuttles having
wefts of the same or of different counts one or more of the shuttles being used for
the back threads or binders and one or more for the face or float. When two counts
of weft are used for the face or float any desired number of picks of fine weft may
be alternated with any desired number of picks of coarse weft for the purpose of
producing an irregular or diamond face. The two different counts of weft may be
used for the back for the same purpose.
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
(1) The production of a curled or cocked appearance upon the face of pile fabrics.
by an irregular arrangement of the float threads.
(2) The use of back or binder threads in an irregular manner to break up tho
regularity of the back and to assist in breaking up the regularity of the face of pile
fabrics.
(3) Weaving pile fabrics with two or more shuttles and two or more counts of
weft substantially as and for the purposes herein before set forth.
