Improvements in Twine and Methods of Making the same.
A communication from abroad by WILLIAM DEERING and 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 object of the invention is to provide a cheap, strong, and pliable twine or cord
adapted for use in grain-binding harvesters, and for other uses: and to this end it
consists, first, in the method of manufacturing twine, consisting in waterproofing a
paper strip and twisting the same into twine, and, if desired, compressing the twine,
with or without the application of wax thereto.
The invention also consists in the improved twine resulting from the procedure
such as above described.
In carrying the invention into effect in the preferred manner, strong paper made
from any suitable stock is taken, and treated with any suitable waterproofing
material, such for example, as a mixture of beeswax, tallow, pine tar, linseed oil, and
acid solution.
The paper is prepared in long strips. It may be made in sheet form and cut into
strips, or the strips otherwise formed, and it may be waterproofed when in sheet
or strip form, as preferred.
It is preferable to pass the strips through a vat containing the waterproofing material
in such manner as to thoroughly saturate the paper therewith.
After the paper has been treated with the waterproofing material, either before
or after it has become dry, it is twisted by any suitable means into a cord or
twine.
In order to render the full strength of the paper available, and to prevent the
danger of breakage which exists when flat paper is twisted directly into twine, the
paper is coiled spirally or rolled or folded fransversely into tubular form and
thereafter twisted tightly into twine. The reduction of the tubular body to twine
may be effected simply by the twisting operation, or the tube may be indented,
crushed, or otherwise reduced to facilitate the twisting operation.
The twine formed by twisting the waterproofed paper strip may be used without
further treatment, but it is preferable to thoroughly coat it with wax such as
bees-wax, or any appropriate compound of wax, or other materials having similar
qualities.
The waxed twine is finally subjected to compression by passing it through a
conical die, between rollers, or subjecting it to the action of other devices which
will have the effect of condensing and hardening the body and smoothing the
surface.
By waterproofing the paper before it is twisted, a better saturation of the fibre is
ecured than is otherwise possible.
The wax coating fills the irregularities or inequalities in the twine, gives a greater
olidity, and produces a smooth surface so that it may be run freely through the
inding mechanism.
While it is preferred to both wax and compress the paper, good results may be
btained when either or both of these steps are omitted, and it is understood that
he invention includes a paper twine which has been twisted and waxed without
ompression, or twisted and compressed without the intermediate treatment with
ux.
'

page_text: A twine of fair quality for some purposes may be produced by twisting a paper
which has not been waterproofed, provided the twine is subsequently waxed and
compressed as herein described.
Small, weak twines have been produced by twisting tissue paper, but this is
believed to be the first invention for producing a paper twine adapted for use in the
binding of grain, the first for manufacturing twine from waterproofed paper, the
first for twisting and compressing a paper twine, and the first for treating the paper
twine with wax.
In the accompanying drawings:
Figure 1 illustrates, in a general way. the mode of forming this paper.
A represents the paper strip, B a vat containing the waterproofing solution through
which the strip is passed, C a rotary throstle of twister through which the strip is
passed and by which it is twisted into twine, D is a second vat containing was
through which the twine is passed, and E a conical die through which the twine is
passed and by which it is compressed.
Figure 2 shows the manner of winding the strip A spirally into iubular form, as
shown at . after which it is twisted down into a hard compact twine a'.
Figure 3 shows the manner of rolling the strip transversely into tubular form,
the tube being collapsed or broken down, as shown at b. and thereafter twisted into
the twine a¹.
Tu Figure 4 the strip A. has its edges folded or turned inward one upon another,
thus producing a hollow strip or tape which is subsequently twisted into twine.
Having now particularly described and ascertained the nature of the said
invention 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 paper twine, substantially as herein described.
2. A twine composed of waterproofed paper, substantially as described.
8. A twine composed of waterproofed paper twisted and coated with wax.
4. A twine composed of waterproofed paper twisted. coated with
compressed.
5. A twine composed of twisted paper and compressed.
6. A paper twine coated with wax.
7. A tubular paper twine.
wax. and
S. The method of making twine which consists in waterproofing a strip of paper
twisting the same into twine, and coating the twine with was.
9. The method of making twine which consists in waterproofing a strip of paper
twisting the strip into twine, coating the twine with wax, and finally compressing the
twine.
10. The method of producing paper twine consisting of first folding or coiling
strip and thereafter twisting the same into twine.
