IMPROVEMENTS IN THE MANUFACTURE OF RIBBED PILE FABRICS
Year: 1882

page_text: LETTERS PATENT to John Richard Hutchinson of Bury, in the County of
Lancaster, for an Invention of IMPROVEMENTS IN THE MANUFACTURE OF
RIBBED PILE FABRICS.
PROVISIONAL SPECIFICATION left by the said John Richard Hutchinson
at the Office of the Commissioners of Patents on the 23rd November 1882.
JOHN RICHARD HUTCHINSON of Bury in the County of Lancaster "IMPROVE-
MENTS IN THE MANUFACTURE OF RIBBED PILE FABRICS
"
"
My invention relates to the manufacture of ribbed pile fabrics known as Cotton
Cords" or fustians and consists in a new system or method of weaving the same
whereby I am enabled to produce a stronger back with a more woolly feel, and a
better appearance on the face or "cockle" (as it is termed in the trade) through
using more extended patterns which also include a greater variety of foundation or
back picks to the round than hitherto employed.
The first part of my invention consists in weaving a cotton cord with 5. 6. 7. 8
or more foundation or back picks to the round with a proportionate number of face
picks intervening, instead of the plan of weaving such cords with not more than 3
or 4 foundation or back picks to the round with the ordinary arrangement of face
picks.
By this method I am enabled to make a stronger and better cord than hitherto
and to obtain a much greater variety of changes in the order of succession of the
picks
I annex hereto two diagrams of analysis of my improved cloth. No 1. is woven
with 5 foundation picks, viz:-1. 4. 7. 10. 13 and N° 2 is woven with 8 foundation
picks viz:-1. 4. 7. 10. 13. 16. 19. 22. The crosses show the back picks and the
dashes are the face picks. These two patterns are merely illustrations of my new
method which may be extended to any number of back picks to the round which a
loom can be made to weave, all of them being, as I consider embraced by my new
system of weaving cords which I claim as my invention.

page_text: The second part of my invention consists in weaving two back picks in succession
between each two groups of face picks one being by preference a binding or
foundation pick and the other a raising pick being more or less floated at the back
as shown in diagram N° 3. This part of my invention is also capable of considerable
extension and variation and I claim all such as included in my invention as by this
means I am enabled to produce a soft woolly back and a full handling cloth with
an excellent appearance.
The diagrams here given show the face picks woven in pairs but this may be
varied and they may be woven singly or in groups of three or four to suit the cloth
as is now the custom. So also the warp threads which are here shown as six to
the cord may be woven any number according to fancy and I therefore reserve to
myself the right to use any variations in the face picks or warp threads in
combination with my new system.

by the said John Richard Hutchinson in the Great Seal Patent Office on the
22nd May 1883.
JOHN RICHARD HUTCHINSON of Bury in the County of Lancaster "IMPROVE-
MENTS IN THE MANUFACTURE OF RIBBED PILE FABRICS
"
My invention relates to the manufacture of ribbed pile fabrics known as "Cotton
Cords" or fustians such as are woven with a "broken twill" back and consists in
a new system or method of weaving the same whereby I am enabled to produce a
stronger back with a more woolley feel and a better appearance on the face or
"cockle" (as it is termed in the trade) through using more extended patterns which
also include a greater variety of foundation or back picks to the round than
hitherto employed.
The first part of my invention consists in weaving a cotton cord with a broken
twill back with 5. 6. 7. 8. or more foundation or back picks to the round with a
proportionate number of face picks intervening instead of the plan of weaving such
cords with not more than three or four foundation or back picks to the round with
the ordinary arrangement of face picks.
By this method I am enabled to make a stronger and better cord than hitherto
and to obtain a much greater variety of changes in the order of succession of the
picks.
I annex hereto several diagrams of analyses of my improved cloth.
The crosses show the back picks and the dashes are the face picks
No 1. is woven with five foundation picks viz 1. 4. 7. 10. 13:
N° 2. is woven with eight foundation picks vis: 1. 4. 7. 10. 13. 16. 19. 22.
N° 3. shows the pattern of a cord woven with five foundation or back picks to
the round. N° 4. 5. 6. are patterns woven with six foundation picks.
By this method of increasing the number of back or foundation picks to the
round or pattern I improve considerably on the cloth woven according to my former
Specification of February 17th 1880. N° 686 in which I give patterns of cords woven
with not more than four foundation picks to the round; as it enables me more
effectually to break the twill back with which it was formerly the custom to weave
cotton cords and thus produce produce a more showy cloth.
To illustrate the second part of my invention which consists of weaving cotton
cords of this class (baving more than four foundation picks to the round) with two
back picks in succession followed by a face pick or a group of face picks, one of the
said back picks being by preference a binding or foundation pick and the other a
raising pick being more or less floated on the back.
No 7. shows a pattern with six back picks
No 8. shows a pattern with seven back picks.
No 9. shows a pattern of this class with eight foundation or back picks
N** 1. 2. 3. 4. 5. 6. 7. 8. 9. show the foundation picks of the different diagrams
separate from the face picks
By weaving cords and more particularly heavy cords after my second manner I
am able to produce a stronger and fuller handling cloth, than under the old plan
of separating each foundation pick from its successor by one or more face picks.
Having now given the diagrams and explanations by which any practical weaver
can produce my new cloth I wish it to be understood that I claim as my invention
First the improved method of weaving what are commonly known as Patent Cotton
Cords or fustians with broken twill backs, and all extensions of the same for
weaving cords or fustians of this class with more than four foundation or back

page_text: picks to the round; and as regards the second part of my invention I claim the
weaving of two back picks in succcession in any of the ways illustrated or any
extension thereof for the purpose of manufacturing ribbed pile fabrics commonly
known as "Patent Cords' or fustians with broken twill backs; all substantially
as herein before described and illustrated by the diagrams annexed.
