Improvements in Twine.
A communication from abroad by WILLIAM DEERING & Co., of Chicago, Illinois,
United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn, in the County of Middlesex, Civil
Engineer, 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 aim of this invention is to produce a cheap and strong twine of suitable
character to be used for binding grain and for other uses, and it consists essentially in
the combination of a sliver, yarn or twine of cotton, jute, hemp, or like fibrous
material combined with a paper twine or strand, the two wound together, or one upou
the other, as hereinafter explained.
One mode of carrying this invention into effect is to coil, roll or otherwise convert
a long paper strip into tubular form, then wind the sliver. yarn or twine of fibrous
material around the paper tube, and finally twist or spin the whole into twine.
Another mode is to twist or spin paper into twine in any suitable manner, and
then wind the sliver, yarn or twine of fibrous material tightly around the paper
twine.
Another mode is to twist or spin the fibres into yarn or twine, twist or spin the
paper separately into twine, and then spin or twist the two together after the manner
commonly practised in uniting strands in the manufacture of twine and cordage.
Still another mode is to fold or twist the paper into tubular form around the sliver
or twine of fibrous material and then twist the whole into twine.
Composite twine made in accordance with either of the modes described above may
be coated with wax or other suitable material of like nature and finished by sub-.
jecting it to compression. Or, either the wax or the compression may be separately
employed. It is to be understood, however, that these are not necessary steps, and
that both may be omitted, if desired.
The steps above described may be carried into effect by mechanism of any
appropriate character. As this mechanism forms no part of the invention, it is
deemed unnecessary to describe it in detail herein.
The accompanying drawings illustrate several equivalent methods of carrying the
invention into effect.
In Figure 1. A represents the paper strip which is usually, but not necessarily,
treated with waterproofing material, such, for example, as a mixture of tallow,
beeswax, linseed oil, pine tar, and an acid solution. The paper strip is first coiled
into tubular form as shown at a. This paper tube is then enveloped by the sliver
or twine of fibrous material B, wound thereon, as shown at a².
After the paper
and fibrous material are thus united, they are twisted by an ordinary throstle
or spinning-head, or other suitable device into twine, a², the effect of the twisting
operation being to reduce the diameter and to inseparably unite paper and fibre in a
hard smooth twine possessing both strength and flexibility in a marked degree.
In Figure 2, A represents the paper strip which is first coiled into tubular form,
as shown at . and then collapsed and twisted into twine, as shown at 3, B is
the fibrous sliver or twine wound tightly and permanently around the outside of
the paper twine.
Referring to Figure 3, A represents the paper strip which is coiled and twisted
into a twine, a³, and B is the fibrous twine. The two twines are laid and twisted
firmly together, producing a composite twine, as shown.

page_text: In Figure 4, B represents the fibrous sliver or twine, A the paper strip which is
first folded in tubular form around the outside of the sliver, after which the two are
twisted tightly together into the finished twine, as shown.
Twine produced as shown in either of the above figures may be waxed, com-
pressed or burnished, if desired.
It has been proposed to spin a strip of paper not waterproofed upon a thread or
yarn, the paper being presented in a flat strip to and wound spirally around the
twine in the act of uniting the two. A composite twine produced in this manner
is objectionable in that the raw edges of the paper are exposed and the paper
unequally strained, so that it is liable to rupture transversely, and also because the
paper cannot be made to remain snugly in place upon the filling.
This invention is believed to be the first to combine with a fibrous core or wrapper,
a paper strand independently twisted, and also twisted thereto.
It is also believed to be the first to combine a waterproofed paper with a fibrous
twine or sliver, and the first to convert the paper to tubular form previous to its being
twisted and united with the fibrous strand.
While only twines which are composed of a single strand of fibrous material and a
single strand of paper have been described and illustrated, it is to be understood that
there may be any desired number of strands of each material.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is:--
1. A composite twine substantially such as herein described.
2. A twine composed of a tubular paper strand and a fibrous strand or slive
twisted together.
3. A twine having a fibrous strand and a paper strand independently twisted, and
twisted together.
4. A twine consisting of paper and fibres united substantially as described, and
coated with wax.
5. A twine consisting of paper and fibres united substantially as described, and
compressed.
6. A twine composed of paper and fibres united substantially as described, coated
with wax and compressed.
7. A twine consisting of a fibrous strand and a strand of waterproofed paper
united substantially as described.
