PROVISIONAL SPECIFICATION.
Apparatus for Treating Card-slivers, Rovings, and the like with
Liquids.
1, Dr. KARL SCHNITER, of No. 4 Tonhallestrasse, Zurich, Switzerland, Chemist,
do hereby declare the nature of this invention to be as follows:→
The apparatus heretofore used for treating card-slivers and the like with liquids
have the disadvantage that they only permit of a single use of the liquid. The
liquid flowing upon the material to be treated must in these apparatus after having
passed once through the material, be raised up again.
The nature of the half-manufactured goods of spinning processes is such that
the treatment of large masses thereof with liquids in the ordinary way is not
permissible, as an entanglement of the separate slivers or bands of the material
would otherwise ensue, whereby the spinning of the same would be rendered much
more difficult. It is therefore necessary to subject only small quantities of the said
half-goods at a time to the treatment, and it has been impossible hitherto to treat
large quantities at one time.
My present invention relates to a construction of apparatus by means of which it
is rendered possible to treat large quantities of card-slivers, rovings, and the like,
with liquid with repeated utilisation of the liquid and without any liability of
entanglement of the separate slivers occurring.
This object is attained by arranging the trays or receptacles for carrying the
materials to be treated, systematically one above the other within a suitable tank
or vessel, whereby the largest possible quantity of goods can be treated at one time
in a vessel of the smallest possible capacity.
In carrying out my said invention I construct a tank or vessel of any suitable
form, into which are introduced in any suitable manner any desired number of
similar trays or receptacles. These trays are formed like drawers and have
recesses in their bottom, constituting receptacles for the material to be treated,
which is wound up in the form of balls. At the lowest point of the recesses
perforations are formed. Each tray is provided with an overflow pipe.
The dye or other liquor is introduced into the top tray through a pipe, and
saturates the goods lying in the same, while the excess flows off from the top tray
through the overflow pipe. In this way the dye liquor flows partly through the
overflow pipes and partly through the perforations in the bottom, from each tray
into the next one below, so as to consecutively saturate the goods contained in each
of the trays. The exhausted dye liquor eventually flows off from the tank through
a discharge pipe.
Each of the trays has at its longer sides a fillet which enables the goods contained
in one tray to be transferred to another.
Such transference is occasionally required, as with the different bleaching,
mordanting, and dyeing operations, different kinds of chemicals are used which may
act upon the trays in different ways. It is therefore sometimes necessary to
employ for the separate operations trays made of different materials in order that
they may resist the action of the chemicals employed.
With so loose a material as card-slivers the said transference is connected
with difficulties, and I have therefore devised the following appliance for effecting
this.
I provide a tray so formed as to fit in an inverted position with a projecting part

page_text: into the top of the other tray like a die in a matrix, the inward projecting part
having cavities that correspond exactly in size and position to those in the ordinary
tray, so that, on placing the auxiliary tray upon the ordinary tray and then
reversing their positions the sliver balls will be contained in the cavities of the
auxiliary tray. The ordinary tray can now be removed and replaced by one of a
different material, after which the position of the two trays is again reversed, so as
to deposit the balls in the ordinary tray, and the auxiliary tray is then removed.
For effecting these motions of the two trays I employ two vertical rotatable discs
placed opposite each other a distance apart about equal to the length of the trays.
On the faces of these discs are firstly two fixed lower rails and secondly two
moveable upper rails that can be made to approach the lower ones by means of
suitable gear such as a screw spindle.
The ordinary tray being placed on the lower rails, the auxiliary tray is placed in
an inverted position on the upper ones, which are then lowered so as to bring the
trays together; the discs are then rotated so as to reverse the positions of the trays,
and the rails are separated so as to allow the ordinary tray to be removed and
replaced by another one, after which the above described operation is repeated in
the reverse manner.
The tank for the trays can, if necessary be mounted on wheels, in order to be
able to readily transport them on rails from one place to another. The above
described apparatus can be made of any suitable neutral material, such as
wood, and consequently offers the advantage that the use of metal parts, which
frequently detrimentally affect the mordanting, as also the dyeing operations, is
entirely avoided.

Apparatus for Treating Card-slivers, Rovings, and the like with
Liquids.
I, Dr. KARL SCHNITER of 4 Tonhallestrasse, Zurich, Switzerland, Chemist,
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 apparatus heretofore used for treating card-slivers and the like with liquids
have the disadvantage that they only permit of a single use of the liquid. The
liquid flowing upon the material to be treated must in these apparatus after having
passed once through the material, be raised up again.
The nature of the half-manufactured goods of spinning processes is such that the
treatment of large masses thereof with liquids in the ordinary way is not permissible,
as an entanglement of the separate slivers or bands of the material would otherwise
ensue, whereby the spinning of the same would be rendered much more difficult.
It is therefore necessary to subject only small quantities of the said half-
manufactured goods at a time to the treatment, and it has been impossible hitherto
to treat large quantities at one time.
My present invention relates to a construction of apparatus by means of which it
is rendered possible to treat large quantities of card slivers, rovings, and the like
with liquid with repeated utilisation of the liquid and without any liability of
entanglement of the separate slivers occurring.
This object is attained by arranging the trays or receptacles for carrying the
materials to be treated, systematically one above the other within a suitable tank
or vessel, whereby the largest possible quantity of goods can be treated at one time
in a vessel of the smallest possible capacity.

page_text: The said apparatus in which the treatment of the card-slivers and the like is to be
effected is shewn diagrammatically on the accompanying drawings.
Fig. 1 shews a longitudinal section through the apparatus, Fig. 2 a plan,
Fig. 3 a cross section.
Fig. 4 shews a perspective view of one of the trays for carrying the materials to
be presently described.
A is a tank or vessel of any suitable form, into which are introduced in any
suitable manner any desired number of similar trays or receptacles B', B', B³, B¹.
These trays are formed like drawers and have recesses in their bottom,
constituting receptacles for the material to be treated, which is wound up in the
form of balls k. At the lowest point of the recesses perforations are formed.
Each tray is provided with an overflow pipe C¹ C' C³ C as shewn more clearly
at Fig. 4.
The dye or other liquor is introduced into the top tray through a pipe E, and
saturates the goods lying in the same, while the excess flows off from the top tray
through the overflow pipe C'. In this way the dye liquor flows partly through the
overflow pipes and partly through the perforations in the bottom, from each tray
into the next one below, so as to consecutively saturate the goods contained in each
of the trays. The exhausted dye liquor eventually flows off from the tank A
through a discharge pipe D.
Each of the trays has at its narrow sides a fillet s by means of which the
introduction of the trays into the tank A is facilitated, enabling them to slide along
guides for transference from one tank to another, and affording a hold for placing
them in position.
The trays rest one upon the other by means of studs not shewn on the drawing.
Such before mentioned transference is occasionally required, as with the different
bleaching, mordanting, and dyeing operations, different kinds of chemicals are used
which may act upon the trays in different ways. It is therefore sometimes
necessary to employ for the separate operatious trays made of different materials
in order that they may resist the action of the chemicals employed, and consequently
it is necessary to transfer the goods from one such tray to another.
The tank A for the trays can, if necessary be mounted on wheels, in order to be
able to readily transport them on rails from one place to another. The above
described apparatus can be made of any suitable neutral material, such as wood,
and cousequently offers the advantage that the use of metal parts, which frequently
detrimentally affect the mordanting, as also the dyeing operations, is entirely
avoided.
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 :-
Apparatus for treating card slivers rovings, and the like by means of liquids,
whereby a more perfect utilisation of the said liquids is effected, and also, the
simultaneous treatment of larger quantities of goods is rendered possible, which
apparatus consists of the arrangement of a series of trays or drawer-like
receptacles B one above the other in a tank or vessel A, which trays have at
bottom perforated recesses or pockets for containing the goods to be treated, the
perforations of which recesses serve to allow the liquid, after saturating the goods
in one tray, to descend into the next tray below, substantially as described.
