PROVISIONAL SPECIFICATION.
Improvements in the Treatment of Cotton or Linen Warps or Warp
Yarns Prior to Weaving.
I, THOMAS PICKLES, of Cairo Mills, Burnley, Lancashire, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The improvements relate to the treatment or preparation of cotton or linen
warps or warp yarns, intended to be employed in the weaving of cotton, linen, or
union fabrics, and which treatment or preparation is effected prior to the same
being woven into cloth, and is applicable both to grey and other yarns.
The object of the improvements is to cleanse, bleach, semi-bleach, dye, or
otherwise prepare and partially, expel the consequent moisture from such yarns
when the same have been wound on to the warp beams or back beams, or during
the winding or unwinding of the same, or both, either in connection with or apart
from the ordinary tapeing or other sizing or dressing machinery.
To accomplish this, and to effect my improvements, I employ a warp beam
formed of a hollow tube or other equivalent, such as a tubular grating, around
which the yarn is wound, and by means of suitable pipes and connections, the
cleansing, bleaching, dyeing or other liquids may be forced through the yarn on
the beam by way of the perforations in such beam, in manner as is now well
understood.
I also attach to such perforated beam, or to the pipes leading thereto, a connection
with a pump or fan blast, by means of which I am enabled to force through
the yarn a blast of hot or cold air, as may be found most desirable, so as to
enable the bulk of the moisture to be rapidly driven off from the yarn on the
beam after it has been subjected to the bleaching, dyeing or other liquid processes
aforesaid.
Variations in detail may be made, such as the arrangement of the pumps,
pipes, valves, and the like, without departing from the peculiar character of the
invention.

COMPLETE SPECIFICATION.
Improvements in the Treatment of Cotton or Linen Warps or Warp
Yarns Prior to Weaving.
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 treatment or preparation of cotton or linen
warps or warp yarns, intended to be employed in the weaving of cotton, linen or
union fabrics, and which treatment or preparation is effected prior to the same
being woven into cloth, and is applicable both to grey and other yarns.
The object of the improvements is to cleanse, bleach, semi-bleach, dye, or
otherwise prepare, and also to partially expel the consequent moisture from such
yarns when the same have been wound on to the warp beams or back beams, or

page_text: during the winding or unwinding of the same, or both, either in connection with or
apart from the ordinary tapeing or other sizing or dressing machinery.
To accomplish this, and to effect my improvements, I employ a warp beam
formed of a hollow tube or other equivalent, such as a tubular grating, around
which the yarn is wound, and by means of suitable pipes and connections, the
cleansing, bleaching, dyeing or other liquids may be forced by the ordinary
pumping apparatus through the yarn on the beam by way of the perforations in
such beam, in manner as is now well understood.
I also attach to such perforated beam, or to the pipes leading thereto, a connection
with another pump or a fan blast, by means of which I am enabled to force through
the yarn a blast of hot or cold air, as may be found most desirable, so as to enable
the bulk of the moisture to be rapidly driven off from the yarn on the beam after
it has been subjected to the bleaching, dyeing, or other liquid processes aforesaid.
The pipes or connections, both to the liquor supply, and to the fan blast or
equivalent, are each provided with a suitable valve or tap, whereby communication
with the warp beam may be opened or shut off, or a compound valve may be
employed at the junction of the pipes.
Thus, when it is desired to force the liquor through the yarn on the warp beam,
the liquor passages are opened, and the air passages closed, and the pump or
equivalent is put in communication, the liquor passing continuously through the
pipes to the warp beam, whether the same is stationary, or whether the yarn is
wound or is winding thereon, until such yarn has been sufficiently treated, when
the liquor supply is shut off, and the fan-blast or pump connection for supplying
the blast of hot or cold air, is opened.
In case any of these operations are accomplished during the winding or
unwinding of the warp beam, such beam is provided with joints or connections
to the pipes or supply passages, which joints are air and water-tight, thus enabling
the beam to freely turn without permitting escape of the liquor or air.
I am aware that perforated warp beams have been employed in connection with
a liquor supply for cleansing, bleaching, or dyeing yarn wound thereon, and Letters
Patent Number 15,136, of 1886, have been granted to me for an invention which
involves the employment of beams of this character for such purpose, but the
apparatus per se does not constitute my present invention, wherein I employ, in
combination, a controllable supply of hot or cold air for expelling the bulk of the
moisture from the yarn on the beam, after it has been treated with liquor.
Variations in detail may be made, such as the design and arrangement of
the pumps, pipes, valves, fans, and the like, 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 apparatus for the treatment of cotton or linen warps or warp yarns, prior
to weaving, the combination of a hollow perforated or equivalent warp-beam, and
apparatus for a forced supply of cleansing, dyeing, or other liquor, with apparatus
for a forced supply of hot or cold air, for the purpose and in manner substantially
as herein set forth.
