Improvements in Apparatus for Treating Yarns with Mercerising or
other Liquors.
We, FREDERICK STUART HOLLAND, of Nether Hey, Birch Vale, in the County
of Derby, Technical Chemist, and JOIN JAMES JACKSON, of Peverill House, New
Mills, in the said County, Bleachworks Manager, do hereby declare the nature
of this invention to be as follows:-
This invention relates to apparatus for holding or stretching yarns in the hank
whilst being treated with liquor more particularly a caustic lye (or other
mercerizing solution) for the purpose of giving a glossy lustrous or silk like
appearance to the yarn. And it is designed to provide a machine which is
simple in construction and can be easily handled and manipulated and to and
from which the yarn can be rapidly applied.
In constructing the machine we provide a suitable frame work comprising
two end uprights or checks suitably connected together top and bottom or
otherwise stayed by bolts or rods to give the desired rigidity thereto.
Between the end uprights or cheeks we place two beams or rails capable of
sliding or being raised and lowered in slides or guides formed in the framing.
Each of the rails provided with a number of transversely projecting arms
or spindles, at one or both sides to receive the hanks of yarn the yarns on the
top rail or beam corresponding in number and position with those in the bottom
rail or beam.
These arms are supported at one end by the beam and at the outer end by
a bracket of suitable shape or structure firmly attached by bolts or otherwise
to the beam or rail. And each is provided with a roller or equivalent which
can be rotated to give the desired movement to the yarn.
The spindles or rollers are driven by chain or toothed gearing being prefer-
ably all geared together with spur wheels and the outer one driven by a chain
from a suitable revolving shaft or spindle or other source of motion.
The top rail or beam is supported by a screw in each cheek or upright of
he framing and is raised and lowered thereby. The bottom one is connected
o the upper one by hanks extending from one to the other and is raised thereby
and falls of its own weight when the top one is lowered. A catch may be pro-
ided in one or both frames to hold it at any desired position. The screws
re operated by bevel wheels and fast and loose pulleys.
The bottom beam may be connected to and raised by an independent screw
f desired by which any desired tension may be applied to draw the two beams
r rails apart but we at present prefer to obtain the desired tension by the
Din Q11

page_text: weight of the bottom rail or beam. Additional weights may be added and
removed as required. The lower rail or beam may also be provided with
counter weights or levers to assist in raising it which can be removed or lifted
when the tension is to be applied.
Below the machine are placed rails upon troughs or vats containing the
alkaline lye or mercerizing or other liquor.
In operation the hanks of yarn are placed over the arms on the top and
bottom rails and the bottom rail suspended by means of the hanks. The vat
or trough of liquor is run under the machine and the top rail lowered by its
screws, the lower rail at the same time descends until the rollers are immersed
in the liquor. The rollers are then set in motion and the hanks are caused
to pass through the liquor in the trough. When sufficiently treated the rails
are raised by the screws the trough removed and another trough containing
water or other liquor run under the machine when the rails are again lowered
and the yarn immersed as before. This treatment can continue with two three
or more troughs or vats of different liquors the yarn being maintained
stretched all the time at a uniform tension by the weight of the lower rail.
The rails are subsequently raised together and the hanks of treated yarn
removed.

Improvements in Apparatus for Treating Yarns with Mercerising or
other Liquors.
We, FREDERICK STUART HOLLAND, of Nether Hey, Birch Vale, in the County
of Derby, Technical Chemist, and JOHN JAMES JACKSON, of Peverill House, New
Mills, in the said County, Bleachworks Manager, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement;―
This invention relates to apparatus for holding or stretching yarns in the
hank whilst being treated with liquor more particularly a caustic lye (or other
mercerizing solution) for the purpose of giving a glossy lustrous or silk like
appearance to the yarn. And it is designed to provide a machine which is
simple in construction and can be easily handled and manipulated and to and
from which the yarn can be rapidly applied and removed.
It consists essentially in constructing the machine with two beams or rails
with lateral arms to receive the yarn the upper beam being supported by a
screw and the lower one suspended from the upper one by the hanks of yarn
thereby obtaining desired tension on the yarn by the weight of the beam or
rail upon it.
It will be fully described with reference to the accompanying drawings.
Fig. 1 front elevation (partly in section
Fig. 2 end elevation.
Fig. 3 transverse sectional elevation.
Fig. 4 plan.
The machine is constructed with a frame of any suitable design comprising
two end frames or cheeks A A¹ stayed together by bolts or rods B top and bottom
or other suitable position to give the desired rigidity.
The frame ends A A' are provided with slides a and between them are placed

page_text: two beams or rails an upper one C and a lower one D capable of sliding or
of being raised and lowered in the slides or guides a formed in the frame A A¹.
To the rails C and D are fitted a number of lateral arms or spindles E
and F projecting transversely at one or both sides of the rails which receive
the hanks of yarn. The arms E on the top rail C correspond in number and
position with the arms F on the bottom rail D and the yarn is stretched from
one of the arms E to one of the arms F.
The arms E and F are fitted into the beams in such a way as to give rigidity
thereto being preferably journalled so as to be capable of rotation. Or they
may be fitted rigidly to the beam with a rotating sleeve or roller G thereon
to give the desired movement to the yarn. The arms or rollers thereon are
driven or rotated by spur wheels H preferably all geared together as shown and
the outer one driven by a chain K from a shaft or spindle or other source of
motion. Or they may be driven by chain gearing.
The top rail or beam C is supported at both ends by the screws L placed in
the frame ends A and it is raised and lowered thereby.
The bottom rail or beam D is connected to or suspended from the upper
one by the hanks of yarn placed over the arms E and F. When the top rail
is raised by the screws L the bottom one is raised with it by the movement
of the yarn hanks and when the top one is lowered the bottom one falls or is
lowered by its own weight. By this arrangement no undue weight is placed
upon the yarn as the tension on the yarn cannot exceed at any time the weight
of the lower rail or beam.
A catch may be provided in one or both of the frames A A¹ to retain the
bottom rail at any desired position after it has been raised to permit of the
putting on or taking off of the yarn. The screws L are operated by bevel
wheels and fast and loose pulleys M.
The bottom rail or beam may be connected to and raised by an independent
screw if desired by which any desired tension may be applied to draw the two
beams or rails apart but we at present prefer to obtain the desired tension by
the weight of the bottom rail or beam. Additional weights may be added and
removed as required. The lower rail or beam may also be provided with counter
weights or levers to assist in raising it which can be removed or lifted when
the tension is to be applied.
Below the machine are placed rails N upon which troughs or vats 0 contain-
ing the alkaline lye or mercerizing or other liquor are brought into position
to receive the yarn. Two such troughs or vats are used one for the liquor and
the other for water.
In operation the hanks of yarn are placed over the arms E and on the
bottom and top rails and the bottom rail is suspended by means of the hanks.
The vat or trough of liquor is run under the machine and the top rail C
lowered by its screws and lower rail D) at the same time descends until the
rollers F are immersed in the liquor. The rollers are then set in motion and
the hanks are caused to pass through the liquor in the trough. When suffi-
ciently treated the beams are raised by the screws the trough O removed and
another trough containing water or other liquor run under the machine when
the beams C and D are again lowered and the yarn immersed as before. This
treatment can continue with two three or more troughs or vats of different
liquors the yarn being maintained stretched all the time at a uniform tension
by the weight of the lower rail D. The rails C and D) are subsequently raised
together and the hanks of treated yarn removed.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:-
1. Apparatus for treating yarns with mercerizing or other liquors constructed
with two booms old..

page_text: arms to receive the yarn the upper rail or beam being raised or lowered by a
screw and the other one supported by the hanks and raised thereby when the
upper one is raised and lowered by its own weight when the upper one is lowered
substantially as and for the purpose described.
2. In apparatus for treating yarns with mercerizing or other liquors con-
structing and arranging the lower stretching beam to weight or stretch the yarn
by its own weight suspended thereon so that the yarn is raised and lowered
whilst under tension substantially as described.
3. Apparatus for treating yarn with mercerizing or other liquor constructed
with two beams to hold or receive the yarn upon which the yarn is raised and
lowered whilst the stretching or tension is maintained and two or more remov-
able and interchangeable troughs which can be brought into position beneath
the yarn beams substantially as described and shown.
4. Apparatus for treating yarns with mercerizing and other liquors con-
structed and arranged in combination substantially as and for the purpose
described and shown.
