Improvements in Apparatus for Treating Cotton, Ramie, or other
Fibrous Materials with Mercerizing or other Liquors in Doubling
or like Machinery.
I, HENRY EDWARD AYKROYD, of Thornfield, Duckworth Lane, Manningham,
in the County of York, Dyer and Finisher, do hereby declare the nature of
this invention to be as follows;
This invention has for its object the treatment of threads or other fibrous
materials while they are on the doubling or like machine, in order that, whereas
formerly two processes were carried out consecutively, now the mechanical opera-
tion, such as doubling, etcetera, and the chemical operation of treating with the
desired liquors may be performed together upon the one machine.
To this end I place in any convenient position upon the doubling, or other
machine two or three or more as may be necessary troughs which run throughout
the length of the machine, into which troughs is run the mercerizing, or other
liquor by any convenient means. Thus in one trough might be placed mercerizing
liquor and in others water for rinsing the material under treatment.
Further in the troughs I mount small squeezing rollers between which the
threads or other material are passed on their way from one trough to another in
order to give a certain amount of squeeze to the material as well as to throw
back into the trough any superfluous liquor which would otherwise be carried
away and wasted. By this means a saving in the liquor is effected. The rollers
may be adjustably mounted in suitable bearings so that any required amount of
nip or pressure may be applied. Either the troughs or rollers or both may be
made all in one length throughout the machine or may be divided up for con-
venience into several sections.
It is obvious that the invention is not limited to the exact details of construction
as described, but that such may be varied as required without departing from the
spirit of the invention. Thus in some cases it may be advisable to have the
troughs in the form of a series of cups for each thread or pair of doubling threads,
each cup having its own supply of liquor and its own pair of nip rollers.

or like Machinery.
I, HENRY EDWARD AYKROYD, of Thornfield, Duckworth Lane, Manningham,
in the County of York, Dyer and Finisher, 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 has for its object the treatment of yarn or threads such as ramie.
jute, China grass, etc., while they are on the doubling machine, in order
that, whereas formerly two processes were carried out consecutively, now the
mechanical operation such as doubling and the chemical operation of treating
with the desired mercerizing liquors, may be performed together upon the one
machine. To this end I place in any convenient position upon the doubling
machine two or three or more as may be necessary troughs which run throughout
the length of the machine into which troughs is run the mercerising liquor by
any convenient means. Thus in one trough may be placed the mercerizing liquor
and in the others water for rinsing the material under treatment.
The invention will be understood from the following description, reference
being had to the accompanying drawing in which Figure 1 shows an end eleva-
tion (partly in section) of a doubling frame with my invention applied thereto,
Figure 2 a front view.
Referring to these figures, A are the pairs of bobbins of single yarn, B one of
the hobbins of double yarn, C hobbins creel, D drag rollers, E squeezing rollers,
hollow drag rollers to be heated either by steam or hot washing-off water and G
the frame of the machine. In a convenient position I place the troughs H which
run throughout the lengths of the machine, into which is run the mercerizing
liquor by any convenient means. Thus in the troughs H is placed the mercerizing
liquor, and in the troughs H¹ the water for rinsing the material under treatment.
In the troughs H. I mount the glass guide rods I under which the yarn is
passed, and above these I mount squeezing rollers E between which the yarn or
threads is passed on its way from one trough to another in order to give a certain
amount of squeeze to the material as well as to throw back into the trough any
superfluous liquor which would otherwise be carried away and wasted. By this
means a saving in liquor is effected. The rollers E may be adjustably mounted in
suitable bearings, so that any required amount of nip or pressure may be applied.
Either the troughs or rollers or both may be made all in one length throughout the
machine, or be divided up for convenience into several sections. The machine
isy preference single sided so as to have an easy access to broken ends and facili-
tate the manipulation of the machine generally.
The mode of action is as follows:
-
The yarn being withdrawn from the bobbins A by the drag rollers D is con-
ducted under the glass guide rollers I in the first mercerizing trough H. It is
then conducted through the first pair of squeezing rollers E, the same process
being continued in the next trough H and so on through the rinsing troughs H¹,
being finally carried round the glass guide rod i and through the hollow drag
rollers F, and conducted in the doubled and mercerized state onto the bobbins B.
The top drag rollers D and the drying rollers F may be fluted if necessary.
A system of circulating the water and the mercerizing liquor may be effected
by having a circulating pump (rotary or otherwise) fixed at a convenient point.
and large enough to meet the requirements of one machine or many, as the case
may be, with pipes connected to one end of trough for inflow and the other end for

page_text: outflow, the whole to be connected with a storage or receiving cistern from and to
which all liquor, caustic or otherwise, will be circulated from and to their various
troughs.
The drag rollers F are preferably slightly larger in diameter than the drag
rollers ) so as to ensure that there is no shrinkage in length.
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:
1. A doubling machine in which the mechanical operation of doubling or the
like and the chemical operation of treating with mercerizing liquor are performed
together upon the one machine instead of two processes being carried out consecu-
tively as hitherto, substantially as described.
2. In a doubling machine or the like, placing in any convenient position on the
machine, troughs in which are placed the mercerizing liquors for treating the
materials, and other troughs in which is placed the water for rinsing the material
under treatment, in combination with guide rollers located in the troughs and
squeezing rollers located above, under and between which the threads are respec-
tively passed and conveyed from one trough to another consecutively, substantially
as described.
3. The general combined arrangement and construction of parts forming the
improved doubling machine substantially as set forth.
