Improvements in the Dyeing of Cotton or Linen Warps or Warp Yarns, in connection with Sizing or like Treatment thereof for Weaving Purposes.
Year: 1895

Improvements in the Dyeing of Cotton or Linen Warps or Warp
Yarns, in connection with Sizing or like Treatment thereof for
Weaving Purposes.
I, TROMAS PICKLES, of Cairo Mills, Burnley, Lancashire, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The improvements relate to the dyeing of cotton or linen warps or warp yarns,
in connection with sizing or like treatment thereof, for weaving purposes, and have
for object to effect such dyeing after the yarns have been wound and prepared upon
the warp beam.
To accomplish this and to effect my improvements, I cause the yarns, after the
same have been cleansed, bleached or otherwise prepared upon the warp beam of
the character and in manner as described in the Specification of Letters Patent
granted to me and numbered 18,971, of 1893 to pass over or round a supplementary
drying cylinder or cylinders, such as are described in the Specification of Letters
Patent granted to me, and numbered 19,177 of 1893, by which means the residue of
moisture remaining in the yarn from the cleansing or other preparing processes is
driven off; and the present invention constitutes a further improvement upon such
aforesaid patented inventions.
After the warps have left the special drying cylinder or cylinders, they are
passed by preference through the sough box, and the size in such sough box is
impregnated with the requisite dye, by which means the yarns pass direct through the
mixture of dye and size in the sough box, and are dyed and sized at one operation,
when the further drying of the yarn is accomplished in the ordinary manner.
I am aware that size for sizing yarns has been employed having a slight tinge of
colour admixed therewith, but per se this has not been effectual as a distinct dye,
and such a process differs from this my present invention, which is for combining
the dyeing process with the various operations previously described.
As a variation, the warps may be passed, after leaving the drying cylinder
aforesaid, through a separate dye box, or dye boxes, after which they may be
carried round an extra drying cylinder or cylinders, or through a drying chamber,
and the whole or part of the dyeing processes may be repeated until the desired
colour is obtained, previous to finally passing to the sough box or other sizing
apparatus.
Variations in detail, such as the number of drying cylinders and their relationship
to the dye and size box or dye box, and the method of applying the dye and size to
the yarn, may be made without departing from the peculiar character of the
invention.
Dated this 7th day of February 1895.

I, THOMAS PICKLES, of Cairo Mills, Burnley, Lancashire, Manufacturer, 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 improvements relate to the dyeing of cotton or liner warps or warp yarns,
in connection with sizing or like treatment thereof, for weaving purposes, and have
for object to effect such dyeing after the yarns have been wound and prepared upon
the warp beam.
To accomplish this and to effect my improvements, I cause the yarns, after the

of moisture remaining in the yarn from the cleansing or other preparing processes
is driven off; and the present invention constitutes a further improvement upon
such aforesaid patented inventions.
After the warps have left the special drying cylinder or cylinders, they are passed
by preference through the sough box, and the size in such sough box is impregnated
with the requisite dye, by which means the yarns pass direct through the mixture
of dye and size in the sough box, and are dyed and sized at one operation, when

As a variation, the warps may be passed, after leaving the drying cylinder
aforesaid through a separate dye box or dye boxes, after which they may be carried
round an extra drying cylinder or cylinders, or through a drying chamber, and the
whole or part of the dyeing processes may be repeated until the desired colour is
obtained, previous to finally passing to the sough box or other sizing apparatus.
But that the improvements may be better understood, I will, with the aid of the
accompanying drawing, proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWING.
The figure shows a general or skeleton view in elevation of apparatus combined
and arranged according to my improvements.
The same letters indicate corresponding parts wherever they occur.
a is a warp beam preferably perforated or one allowing of the necessary previous
preparation, and from which the warp 6 is carried to the supplementary drying
cylinder c which drives off from such warp the residue of moisture remaining from
any previous drying operation, either upon the warp beam or otherwise.
The size in the sough box e of the sizing apparatus f is preferably impregnated
with the requisite dye, by which means the yarns may be dyed and sized at one
operation by passing from the drying cylinder c to such sough box e containing the
mixture of dye and size, in which case the warp yarns follow the course marked
by the full lines b. Or, if necessary, the whole or part of the dyeing and sizing

page_text: processes may be repeated until the desired colour is obtained; or the sough box e
containing the mixture of dye and size, or of size alone, may be used inconjunction
with a dye box e¹, or other dyeing apparatus, in which case the direction of travel
of the warp would follow a course through e indicated by the dotted lines.
Variations in detail, such as the number of drying cylinders and their
relationship to the dye and size box or dye box, and the method of applying
the dye and size to the yarn, may be made without departing from the peculiar
character of the invention.
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 :-
In the dyeing and sizing of cotton or linen warps, or warp yarns, the combination
of a warp beam or beams with drying cylinders and dyeing and sizing apparatus
of the character, and for the purpose, and in manner substantially as herein shown
and described.
Dated this 6th day of November 1895.
