I, ROBERT GRIERSON LAIDLAW of Hawick in the County of Roxburgh, North
Britain, Woollen Manufacturer do hereby declare the nature of the said invention
for IMPROVEMENTS IN THE MANUFACTURE OF CERTAIN KINDS OF YARNS to be as
follows:--
This Invention, which relates to improvements in the manufacture of certain
kinds of yarns used in weaving, has for its object to produce on or in such yarns,
one or more colours at any desired intervals and proportions of the said yarns.
The Invention consists in subjecting yarns of the classes known as loop yarns,
knot yarns, chenille yarns, spot yarns as well as spiral yarns to the operation of
print dyeing," the effect of which operation is to produce the necessary variations
of colour at the desired intervals or spaces on the said yarns.

I, ROBERT GRIERSON LAIDLAW of Hawick, in the County of Roxburgh, North
Britain, Woollen Manufacturer do hereby declare the nature of my invention for
IMPROVEMENTS IN THE MANUFACTURE OF CERTAIN KINDS OF YARNS and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My Invention, which relates to improvements in the manufacture of certain
kinds of yarns used in weaving, has for its object to produce on or in such yarns,
one or more colours at any desired intervals and proportions of the said yarns.
The Invention consists in subjecting yarns of the classes known as loop yarns,
knot yarns, chenille yarns; spot yarns as well as spiral yarns to the operation of
"print dyeing," the effect of which operation is to produce the necessary variations
of colour at the desired intervals or spaces on the said yarns.
In order that my said Invention may be properly understood and readily carried
into effect, I will now proceed to describe the drawings hereunto annexed.
Figure 1 is a view of a portion of loop yarn.
Figure 2, is a view of a portion of knot yarn.
Figure 3 is a view of a portion of chenille yarn.
Figure 4, is a view of a portion of spot yarn and
Figure 5, is a view of a portion of spiral yarn, to all of which said kinds of yarns
my improvements are applicable.
My Invention consists in subjecting any or all of the yarns which are represented
upon the annexed drawings or any of the yarns known by or under the before-
mentioned distinctive titles, excepting those yarns known as cut chenille yarns, to
the operation of "print dyeing the effect of which is to produce variations of
colour at intervals or spaces on the said yarns.
As an example of such variations of colour it may be supposed that the part of
the yarn between a. and b, Figure 1 graduates from a green bronze to a yellow,
and from b, to c, the said yarn graduates from a yellow to an emerald green and
from c, to d, from an emerald green to green bice and from d, to e, from green bice
to green bronze, and from e, to f, from green bronze back to yellow.
It is to be understood that any colours may be employed in the process of "print
dyeing" the before mentioned yarns and that the said colours may be arranged in
any order and further, that the said yarns may have a distinct print of each or
any colour between the parts indicated at a, b, c, d, e, and f. I also desire it to be
understood that the intervals or spaces at which the said yarns are coloured may
be of extent greater or less than those represented upon the annexed sheet of
drawings.
Under any one of the herein before mentioned distinctive titles it is well known
that the kind of yarn referred to may be varied in many ways for example, the
loops and knots shewn upon the annexed drawings may be nearer to or farther
from each other and the spot yarn represented at Figure 4, may be formed with
or without the loops g, there shewn, yet all such yarns and various forms of such

page_text: yarns whether they be formed of wool, mohair, or cotton or of thickness greater or
less than that represented upon the annexed drawings are well understood among
spinners as classified under the aforesaid distinctive titles.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
First. The improvements in the manufacture of certain kinds of yarns, known
as loop yarns, knot yarns chenille yarns, spot yarns and spiral yarns by subjecting
them to the operation of "print dyeing" all substantially as herein before set forth
with reference to the annexed drawings.
Second. Yarns known as loop yarns, knot yarns, chenille yarns, spot yarns and
spiral yarns subjected to the operation of "print dyeing" substantially in the
manner hereinbefore set forth with reference to the annexed drawings.
