Machine for Mercerising and otherwise Treating Hanks or Skeins
under Tension.
I, LUDWIG SCHREINER, of 75/77, Berlinerstrasse, Barmen-Rittershausen, Germany
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This machine for mercerising and otherwise treating hanks or skeins under
tension is intended to obviate the inconvenience attending the motion of the
vessel containing the liquid, or of the stretching apparatus, and of the banks or
skeins for the purpose of wetting the latter with the different liquids.
For this purpose the successive dampings or wettings of the hanks or skeins
with the different liquids, are regulated by automatic filling and emptying of the
damping trough or vessel by means of slides or valves which are operated by means
of the shaft which actuates the hanks or skeins.
In order that the liquid in the damping trough may be kept at a constant level,
an intermediate vessel with a float valve may be arranged or provided, the opening
of which is effected by means of discharge valves.
The accompanying drawing furnishes an example of the form in which the
invention is applied for the mercerising of hanks or skeins under tension.
Figure 1 thereof, is a front view partly in section.
Figure 2 is a similar side view.
Figure 3 is a plan.
The hank or skein running over the tension rollers ab is treated successively
in the damping or steeping vessel or trough c with lye, cold and hot water, diluted
acid and water, each of these liquids passing through the admission pipes d e f g
into the several valve-boxes and thence through the intermediate vessel h and the
connecting-pipe i into the damping or steeping vessel c. The discharge of the
liquid after being used is effected by means of the connecting-pipe i, the inter-
mediate vessel h, the valve-boxes and the discharge pipes k l m n.
In order that the admission and discharge of the various liquids may be effected
automatically, the admission and discharge pipes are furnished with valves opgr
or stuv, which are opened automatically at the proper moment by means of a
driving-shaft through the medium of cam-discs; and after the operation of filling
or emptying has been effected, are lowered again by the valve springs w and r.
For the purpose of preserving a constant level in the intermediate vessel h a float
valve is provided, which prevents any further admission of liquid, as soon as
the latter reaches a certain height.
The opening of the float valve when the emptying operation is effected, is
brought about automatically by means of the discharge valves s t u v, which, in
moving upwards, come into contact with the pivoted lever z connected with the
float valve.

emptying of several steeping vessels or troughs.

ace for mercerising and otherwise Treating Hanks or Skeins
under Tension.
I, LUDWIG SCHREINER, of 75/77, Berlinerstrasse, Barmen-Rittershausen, Germany,
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:-
This machine for mercerising and otherwise treating hanks or skeins of yarn
under tension, is intended to obviate the inconvenience attending the motion of the
vessel containing the liquid, or of the stretching apparatus and of the banks or
skeins for the purpose of wetting the latter with the different liquids.
In this apparatus for mercerising and similarly treating yarn in hanks, the
successive treatment of the yarn with the different liquids is automatically effected
during the requisite space of time by charging and emptying the vessel employed
in the treatment by means of a number of supply and discharge valves, or the
like, operated by the same shaft. If the yarn cylinders and the valves are set in
motion by means of the same driving shaft, such direct connection
of the two driving mechanisms will ensure uniform treatment, and in
consequence, uniformity in the goods so treated, more particularly in the case of
mercerised goods.
In order that the liquid in the steeping vessels may be kept constantly at the
same level, an intermediate receptacle or hopper with a float-valve may be intro-
duced between the liquid supply pipes and such vessels, the valves being arranged
to be opened automatically by the opening of the discharge valves or the like.
The drawings filed with my Provisional Specification illustrate by way of
example, one form of the invention as applied to the mercerising of yarn in hanks
under tension. On those drawings, Figure 1 is a front view, partly in section.
Figure 2 is a similar side view. Figure 3 is a plan.
The yarn running on tension rollers a b is treated successively in the steeping
vessel or trough c during the requisite space of time with lye, water, diluted acid,
and again with water, each of these liquids being conducted to the vessel c through
the supply pipes d e f or g, the several valve boxes, the intermediate receptacle or
hopper and the connection pipe i.
The discharge of the several liquids after use is effected by means of the con-
nection pipe, the intermediate receptacle or hopper h, the valve boxes and the
discharge pipes k l m n. For the purpose of automatically regulating the supply
and discharge of the different liquids, the supply and discharge pipes are furnished
with valves o p q r or s t u v, which can be automatically raised up at any time
as described by means of cam-discs, and lowered again by means of the valve
spring wo or after the filling or emptying has been effected. The motion of the
yarn roller a and of the cam-discs is obtained from the same driving shaft, the
motion of which is transmitted by belts or other suitable means to the yarn

page_text: w and to the controlling shaft for the supply valves o p q r and thence to the
controlling shaft for the discharge valves stu v.
In order that the liquid in the vessel o may be kept constantly at the same
level, a float valve y is provided in the intermediate receptacle or hopper h, which
5 stops the supply or entrance of the liquid as soon as the latter has reached a
definite height. The opening of the float-valve when the emptying takes place,
is effected automatically by means of the discharge valves s t u v which when
moving upwards come into contact with the pivoted lever z, the short end of which
is connected with the float-valve.
The apparatus may also be employed for supplying and emptying a number of
steeping vessels simultaneously. The discharge valves may be opened by lower-
ing instead of raising the same; the alterations necessary for such modification
will be apparent.
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. An apparatus for mercerising and otherwise treating hanks or skeins under
tension, comprising means for the successive treatment of the yarn with the
different liquids during the requisite space of time by automatically supplying
and emptying the steeping vessels employed in the treatment of the yarn, by
means of a number of supply and discharge valves (corresponding with the different
liquids) actuated by the same shaft, substantially as described.
2. An apparatus for mercerising and otherwise treating hanks or skeins under
tension, wherein the motion of the yarn roller and of the valves is obtained by
means of the same driving shaft, for the purpose of ensuring uniform products,
substantially as set forth.
3. An apparatus for mercerising and otherwise treating hanks or skeins under
tension, in which an intermediate receptacle or hopper is introduced between the
liquid supply pipes and the vessel used for treating the yarn, this receptacle being
furnished with a float-valve which is automatically opened by the opening of the
lischarge valves, or the like, for the purpose of keeping the liquid in the steeping
essel for treating the yarn at a constant level, substantially as described.
