Improvements in and connected with the Drying, Conditioning, and
like Treatment of Yarn in Cops and the like after Dyeing,
Bleaching, Washing, or like Operations.
I, LAWRENCE WILSON, Director of The Manchester Dyeing Co., Limited,
Lumb Dye Works, Edenfield in the County of Lancaster, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in and connected with the drying and
conditioning of yarn which has been dyed bleached washed or otherwise subjected
to a wet treatment in the form of cops and the like, upon hollow perforated
injection tubes or spindles.
Hitherto, the drying and conditioning of the cops has been somewhat expensive
and tedious and often unsatisfactory, but by the adoption of my invention the
whole operation is rendered more uniform in its results, takes less room and less
time, and involves less labour.
My improvements consist in drying conditioning and similarly treating the cops
and the like, whilst they are still upon the perforated injection tubes or spindles
upon which they have been previously treated. For this purpose the cop filled
spindles, if they are not already so arranged, are arranged upon perforated plates,
preferably of a portable size and these plates are placed upon a suction box chamber
or chest in such a manner that any air withdrawn from the box chamber or chest
can be replaced only by air passing through the cops and injection spindles.
The drying of the cops is effected by exhausting air from the suction chamber,
or alternatively, by forcing air through the chamber tubes and cops, or the two
processes may be alternated. The drying is facilitated by arranging the cops,
whilst air is being drawn or forced through them, in a room or closed space heated
by steam pipes or otherwise.
When desired, the air after it has been passed through the cops may be led to a
condensing apparatus by means of which the moisture may be removed therefrom,
in which case the same volume of air is used over and over again for drying.
In conditioning, moist air is similarly passed through the cops.

1, LAWRENCE WILSON, Director of The Manchester Dyeing Co. Limited,
Lumb Dye Works, Edenfield, in the County of Lancaster, 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 :-
This invention relates to improvements in and connected with the drying and

page_text: conditioning of yarn which has been dyed, bleached, washed, or otherwise subjected
to a wet treatment in the form of cops and the like, upon hollow perforated
injection tubes or spindles.
Hitherto, the drying and conditioning of the cops has been somewhat expensive
and tedious and often unsatisfactory, but by the adoption of my invention, the
whole operation is rendered more uniform in its results, takes less room and less
time, and involves less labour.
My improvements consist in drying, conditioning and similarly treating the cops
and the like as hereinafter described, whilst they are still upon the perforated
injection tubes or spindles upon which they have been previously subjected to the
preliminary treatment. For this purpose, the cop filled spindles, if they are not
already so arranged, are arranged upon perforated plates, preferably of a portable
size, and these plates with the cops upon them, are placed upon a suitable suction
chamber box or chest, in such a manner that when a vacuum or partial vacuum is
created in the suction chamber, the external air steam gas or the like with which
the cops are to be dried or conditioned, is drawn into the suction chamber through
the cops and injection spindles.
It is desirable that the drying or conditioning should in general cases, be effected
as soon as practicable after the preliminary process of dyeing, bleaching, or
the like.
It will be obvious that precautions should be taken to secure that the injection
tubes fit the perforations of the plate on which they are carried, that any unoccupied
perforations should be closed, and that the plate itself should fit upon and close the
opening in the suction chamber prepared for its reception, so that no air gas or
fluid can afterwards enter the suction chamber except through the cops and the
injection tubes.
In the ordinary processes of drying and conditioning the yarn on the cops, it is
desirable that the suction chamber, with the cops thereon, should be arranged in a
chamber or stove. When so arranged the chamber or stove can be supplied with
the cold, heated, or moistened air, steam, gas, or other fluid of a similar nature
required to be drawn through the cops for the particular purpose in view. Or,
alternatively. the cops and injection tubes upon the suction chamber may be covered
or enclosed with an air-tight box-like casing, to the interior of which the air or
other gaseous fluid may be admitted. The heating, when desired, of the enclosed
space around the cops may be effected by steam pipes or otherwise.
It is sometimes advantageous, when the cops have only to be dried, to arrange a
closed circulating system. In such a case, the air is arranged to pass from the
suction chamber to a condenser and thence to the exhaust fan or air pump, whence
it returns to the enclosed space around the cops. A similar device may be
employed when the cops have to be treated by a fixed gas.
It will also generally be found advantageous to arrange an air-tight receiver
between the suction chamber and the exhaust fan or air-pump, or the suction
chamber itself may be made sufficiently capacious to act as a receiver.
In order that my invention may be more readily understood I have appended a
sheet of drawings reference to which is made hereinafter.
AA indicate the cop filled spindles, placed upon the perforated plate B arranged
to fit upon and close a suction chamber C. This chamber communicates through a
pipe D with a pump or other similar exhausting device E, by means of which the
air or other gaseous fluid contained in the stove F within which the chamber C is
placed is drawn through the cops. The air or the like may be returned to the
stove by the pipe G. H is a vessel which acts both as an airtight receiver and a
condenser, and is interposed in the path of the pipe D between the stove F and the
pump E. I is a trough surrounding the bottom of the vessel and containing water.
The water of condensation may be withdrawn by means of a valve controlled
pipe K. Within the stove F is a number of steam or other pipes J by means of
which the temperature may be varied.

page_text: 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 :-
The herein before described method of drying or conditioning yarn in cops after
a preliminary wet treatment, by drawing air steam gas or other desired similar
fluid through them, substantially as and by the means set forth.
Dated this 15th day of June A.D. 1895.
