Improvements in Crochet Cottons and in the Manufacture thereof.
I, EDMUND WILLIAM BARLOW of Harland near St. Pölten in the Empire of
Austria, Doubling Manager, 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 :-
This invention relates to an improved crochet cotton and an improved method of
and means for manufacturing the same, and the invention has for its object to obtain
the aforesaid crochet cottons in a much better quality and at a considerably cheaper
price than heretofore. Referring to the drawings.
Until now twist cops, that is to say, yarn which is twisted in the direction of the
arrow figure 1, have been used for the manufacture of crochet cottons in the
following manner :
Two or more single threads or ends of the aforesaid twist cops have been combined
and twisted together in the direction of arrow figure 2 to a double or morefold
thread, which is termed prepared ends; finally, two or more of the prepared ends
have been combined and twisted together in the direction of arrow figure 3 in order
to obtain the desired finished crochet cottons.
It is evident, that the aforesaid method of manufacturing crochet cottons has a
great disadvantage, viz. in the twisting of the prepared ends or threads, as they
are twisted the reverse way to the yarn or twist cops which is at present used, there-
fore they require much more twist than if they were twisted in the same direction,
consequently it makes the twisting of the prepared ends expensive.
After careful and long experiments I have found means to obviate the aforesaid
disadvantage and obtain a much cheaper and better looking crochet cotton by using
a yarn that is twisted the reverse way to twist cops, viz. weft way, or reverse twisted
yarn, or yarn that is twisted in the direction of arrow figure 4. Two or more single
ends of the aforesaid reverse twisted yarn are combined and twisted together in the
direction of arrow figure 5 and finally two or more of the aforesaid combined ends
are twisted together in the direction of arrow figure 6.
It can easily be seen that the direction of arrows figs. 4 & 5 is the same, and
that the second twisting in the direction of arrow fig. 5 constitutes merely a con-
tinuation of twisting in the direction of arrow fig. 4.
Reverse twisted yarns, (: a yarn that is twisted in the direction of arrow figure 4)
have never been used until now for the manufacture of crochet cottons.
The advantages of my improved method, are:
1st. As a reverse twisted yarn soft spun is used, it can be bought cheaper than
twist cop yarn.
2nd. Over 30 per cent. is saved in the first time doubling and twisting.
3rd. The finished crochet cottons have a fine cabled appearance.
4th. The cotton does not curl during crocheting, which saves time and labour
in working.
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 I
claim is :-
I.) In the manufacture of crochet cottons, the use of reverse twisted yarns, that
is to say, of a yarn which has been twisted in the direction of arrow figure 4,
whereby the single reverse twisted yarn as well as the two or more are twisted in
one and the same direction, whilst the twisting in finishing the crochet cotton is
carried out in a direction opposite to the above turnings, substantially as described.

page_text: II.) As a new article of industry crochet cottons manufactured from reverse
twisted yarns in the manner substantially as described.
Dated this 5th day of July 1889.
