strength of yarn twisted by this system
Is from nine to 15 per cent stronger than
that twisted by the present system.
What is true OF spinning IL true OF
twisting. the same parts being done away
with and the even twist Is great ad-
vantage where yarn is 10 be dyed because
even twisted yarn takes the dye liquor
all alike and gives an even color. where In
the present system some parts or the yarn
have a harder twist than others, and the
hard places will not take the dye liquor
as well as the soft twisted places. and
the consequences are uneven color. This
has caused a great many mills 10 dye the
cotton before using, but this they do not
like TO do as colored cotton Is hard TO
handle.
In the present system they are obliged
on account OF the drag OF the travellers
lin wet twisting) to keep them covered
with tallow, which has to be cleaned on
and replaced at least once a week, and be-
sides being an expense for labor IL causes
large amount OF waste as every time
the yarn breaks it comes In contact with
the tallow which stains and destroys IL.
The new system does not require tallow
and will not oilstain the yarn.
There is large field for this system,
for twisting such fbres fax and jute
that cannot be twisted on rings with
travellers, but have to be twisted on what
are known as iy-frames, and the limit of
per minute. while we have a ring 3%
inches In diameter which size Is equal TO
f1ier that can not be run over 100 revo-
lutions per minute, and the company has
run this ring 300 revolutions per minute,
without the slightest trouble.
This system can be applied to present
frames now In use, with slight changes
OF the frame and new frames can be fitted
with IL at the same price as the present
system.
In the old system. the yarn is twisted
by what Is called a traveller. which Is a
small wire that is carried around by the
thread, and the least resistance from any
cause will retard II and give imperfect
yarn. while In this system, the yarn is
twisted by fixed guides on the top OF the
ring and as this ring Is driven by power,
II carries the yarn around and gives II a
perfect twist.
BY an Increase OF 25 per cent I'm produc-
tion new mill can be started with $1,000
spindles OF this new system. and have
the same capacity as mill OF 10000
spindles of the present system, thereby
saving s42,500 on the first cost OF the
plant. and $S525 per year thereafter.
The company has a sample frame run
ming. spinning number so yarn. The front
roll. running 40 revolutions per minute.
where the highest speed called for by the
present system Is 80 revolutions per min
ute, and all the experts that have seen Il,
say that although IL Is giving an in
crease I'm production of about 30 per cent,
| II Is running better than any other spin
| ming, on the same number of yarn. BY
this new system the means OF fabrication
is so perfect, that II runs as easily as the
present system now In use. and after once
oling will run for months. There is a ring
on the frame mentioned above that has
run continually the past 10 months, and
| Is In as good shape now as when started,
| showing there is no wear.
Increased strength OF the yarn is assur-
ed and every test made of the breaking
strength shows II TO have been more than
10. per cent above the standard
