PROVISIONAL SPECIFICATION.
Improvements in Weaving Crape-like Fabrics.
I. JAMES EDELSTON, of Manchester Mill, Proston, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
The improvements relate to weaving, and have for object the production of
cotton fabrics which shall have a peculiar crape effect, or unevenness of surface, as
an immediate result of weaving, giving an imitation of certain hand made foreign
silk goods.
To accomplish this, and to effect my improvements, I employ two divergent
kinds of yarn, which may be used as weft, or as warp or both. That is to say, the
one kind of yarn is twisted in the ordinary manner in one direction, and the other
kind of yarn is twisted reversely or in the contrary direction. When employing
these two kinds of yarn for weft in weaving in the loom, I use two or more shuttles,
by means of drop shuttle boxes, or revolving or other shuttle boxes, and one shuttle
is charged with a cop of right twisted weft, and another with reverse twisted weft.
These shuttles are picked alternately, each passing through the warp sheds one
two or more picks at a time, necording to the particular form of crape or irregular
surface of the fabric desired.
In similar manner when I employ these two opposite twisted yarns in the warp,
I intersperse the same in alternate threads, or groups of threads, as the case may
require, which may be wound for the purpose on one or more beans.
Variations in detail and arrangement may be made, to a great extent, as regards
the number and combinations of the warps or the picks of weft or both, and the
method may be adopted in one or the other or in both warp and weft, without
departing from the peculiar character of the invention; which mainly consists in the
combination during weaving, of yarns, in warp or weft or both, which are twisted
in opposite directions, for the purpose of producing special crape or elastic effects
in weaving cotton goods.

COMPLETE SPECIFICATION.
Improvements in Weaving Crape-like Fabrics.
1, JAMES EDELSTON, of Manchester Mill, Preston, 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 improvements relate to weaving, and have for object the production of
cotton fabrics which shall have a peculiar crape effect, or unevenness of surface, as
an immediate result of weaving, giving an imitation of certain hand made foreign
silk goods.
To accomplish this and to effect my improvements, employ two divergent
kinds of yarn, which may be used as weft, or as warp or both. That is to say, the
one kind of yarn is twisted in the ordinary manner in one direction, and the other
kil of yarn is twistel reversely or in the entrary direction. When employing
these two kinds of yarn for weff in weaving in the loom, I use two or more shuttles,
by means of drop shuttle boxes, or revolving or other shuttle boxes, and one shuttle
is charged with a cop of right twisted weft, and another with reverse twisted

page_text: weft. These shuttles are picked alternately, each passing through the warp sheds
one, two, or more picks at a time, according to the particular form of crape or
irregular surface of the fabric desired.
In similar manner when I employ these two opposite twisted yarns in the warp, I
intersperse the same in alternate threads, or groups of threads, as the case may
require, which may be wound for the purpose on one or more beams.
Varintions in detail and arrangement, inay be made, to a great extent, as regards
the number and combinations of the warps or the picks of weft or both, and the
method may be adopted in one or the other or in both warp and weft, without
departing from the peculiar character of the invention; which mainly consists in
the combination during weaving, of yarns, in warp or weft or both, which are
twisted in opposite directions, for the purpose of producing special crape or elastic
eflects in weaving cotton goods.
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 1
claim is
1. In weaving cotton goods, the combination of alternate picks or alternate
numbers of picks of weft twisted or spun in reverse directions for the purpose of
producing crape effects, and in the manner substantially as herein described.
2. In weaving cotton goods, the combination of alternate warp threads or
alternate groups of warp threads of yarn twisted or spun in reverse directions, for
the purpose of producing crape effects, and in the manner substantially as herein
described.
3. In weaving cotton goods, the combination of alternate picks or alternate
numbers of picks of weft, and also of alternate warp threads or alternate
groups of warp threads of yarn spun in reverse directions, for the purpose of
producing crape effects, and in the manner substantially as herein described.
4. Cotton goods woven with alternate picks or numbers of picks, or with
alternate warp threads or alternate groups of warp threads, or with both, of yarns
twisted or spun in reverse directions, for the purpose of producing crape effects,
and in the manner substantially as described.
