Improvements in Apparatus for Dyeing, Scouring, Bleaching, and
otherwise Treating Yarn in Cop or other similar Compact Form.
We, AUGUST GRAEMIGER, Chemist, and JOSEPH GRAEMIGER, Dyer, both of
Glen Villa, Edenfield, near Bury, in the County of Lancaster, do hereby declare
the nature of this invention to be as follows :-
This invention relates to that class of apparatus for dyeing, scouring, bleaching
and otherwise treating yarn in cop or other similar compact form, in which it is
placed on hollow perforated injection tubes or spindles, by means of which latter
and the assistance of suitable pump or pumps the yarn is exhausted of air and
impregnated with dye or other suitable liquor, by drawing or forcing it through
and ultimately extracting the superfluous liquor from the same.
Heretofore the means employed for thus treating yarn in cop or other similar
compact form, rendered it, for various reasons, impossible to perform the treatment
in large batches so as to reduce the matching of the same, or with liquor at a high
temperature and thus increased the difficulty of obtaining an equal shade in the
yarn throughout, which is of the greatest importance, as well as necessitating a
separate apparatus for drying the yarn after being dyed or otherwise treated.
To remedy these defects our improvements consist in the use of one or more
interchangeable plates or carriers, serving for the reception of hollow perforated
injection tubes or spindles carrying the yarn to be treated, which plates or carriers
are adapted to be placed in a treating tank, capable of being hermetically closed,
in communication with a liquor and air pump or pumps and suitable supply pipes, in
such a manner, as to subject the yarn in cop or other similar compact form, to air
exhaustion on the plates carrying it being placed into, and on being removed out of
the treating tank, to liquor extraction, whilst when in the same it may be impreg-
nated with dye or other suitable liquor or suitable gases through the action of a
force or suction pump or pumps, either with or without preliminary air exhaustion
or on hermetically closing the treating tank through the combined action of com-
pressed air or steam and a suction pump and finally dryed in the same apparatus by
superheated air or steam.
Near the lower end we employ, in the said treating tank, a perforated bottom and
below the same a steam coil, to permit of heating the dye or other liquor in the
treating tank. The sides of the said treating tank, a suitable distance above-
the perforated bottom, we bring, by suitable pipes, into communication with a
circulating pump, the return pipe of which is in communication with the space of
the treating tank containing the said steam coil.
The plates carrying the yarn to be treated in cop or other similar compact form,
are arranged to slide in grooves formed at the ends and in the perforated bottom of
the treating tank at a short distance apart from the orifice of the pipes leading to
the circulating pump, the said orifices being furnished with deflector plates, so as
to divide the suction of the pump equally over the whole surface of the said plate
or carrier, the upper ends thereof being supported by a rim furnished with a
packing, thus forming a chamber between the said plates or carriers and the side of
the treating tank. Above the said rims two other similar rims are formed a
suitable distance apart from each other and pipes arranged between the same, com-
municating with an air pump.
The said plates or carriers when lowered into, or lifted out of the treating tank,
by suitable appliances, bear against the said rims and thus form each space between,
into a comparatively narrow chamber, so as on communication being established.
between the same and the said air pump, the yarn on the plates-or-carriers is

page_text: respectively subjected to air exhaustion and liquor extraction, which owing to the
plate or carrier being gradually passed over the said chambers and the compara-
tively small number of injection tubes or spindles thus brought in communication
therewith successively, requires only a small air pump, and effects a more uniform
exhaustion of air and extraction of liquor.
The upper end of the said treating tank we furnish with a readily removable
hermetically closing lid, by means of which the yarn in cop or other similar com-
pact form may be dyed or otherwise treated under vacuum by exhausting the
treating tank of air and afterwards admitting and circulating the dye or other
liquor through the same.
In cases where the dye or other liquor is used in a very hot state, air or steam
may be compressed onto the same whereby the action of the circulating pump is
assisted and a thorough impregnation of the yarn effected, or suitable gases may be
used only.
In connection with the said treating tank, we arrange a number of dye or other
liquor supply cisterns, so as to permit of readily changing the dye or other liquor
at will.
A number of the described apparatus may be arranged in connection with each
other, so as to perform the various operations simultaneously and thereby save a
great deal of time and labour, which otherwise would be incured in placing on or
removing the cops from the plates or carriers.

Improvements in Apparatus for Dyeing, Scouring, Bleaching, and
otherwise Treating Yarn in Cop or other similar Compact Form.
We, AUGUST GRAEMIGER, Chemist, and JOSEPH GRAEMIGER, Dyer, both of
Glen Villa, Edenfield, near Bury, 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 3
particularly described and ascertained in and by the following statement :-
This invention relates to that class of apparatus for dyeing, scouring, bleaching
and otherwise treating yarn in cop or other similar compact form, in which the yarn
is placed on hollow perforated injection tubes or spindles, by means of which latter
and the assistance of suitable pump or pumps the yarn is exhausted of air and 3
impregnated with dye or other suitable liquor or gases by drawing or forcing such
liquor or gases through and ultimately extracting the superfluous liquor from the
yarn.
Heretofore the means employed for thus treating yarn in cop or other similar
compact form, rendered it, for various reasons, impossible to perform the treatment
in large batches so as to reduce the matching of the same in shade, or with liquor
at a high temperature and thus increased the difficulty of obtaining an equal shade
in the yarn throughout, which is of the greatest importance as well as necessitating
a separate apparatus for drying the yarn after being dyed or otherwise treated.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section of our apparatus on line A-B of Fig. 2, which
latter is partly a side view and partly a vertical section, and Fig. 3 a plan in section
on line C-D of Fig. 1.
In carrying out our invention and to remedy the aforesaid defects our improve-
ments consist in the use of one or more, by preference four, interchangeable plates
or carriers a, serving for the reception of hollow perforated injection tubes or
spindles 6 carrying the yarn b¹ to be treated, which plates or carriers a are adapted

page_text: to be placed in a treating tank c, two of them being used in the treating tank_c,
whilst the other two serve as reserve plates or carriers, to permit of exchanging the
treated yarn for untreated yarn. In order to render the treating tank e capable of
being hermetically closed a lid d is employed, having on its underside a rim d
adapted to fit onto a packing c¹ placed into a groove formed in the flange of the
treating tank c and secured thereto by means of hinged bolts c
Near the lower end we employ, in the treating tank c, a perforated bottom and
below the same a steam coil, to permit of heating the dye or other liquor in the
treating tank c. The sides of the treating tank c, a suitable distance above the
perforated bottom, we bring, by suitable pipes g, g' respectively into communication
with a circulating pump (not shown), the return pipe h of which is in com-
munication with the space of the treating tank c, which is also furnished with an
inlet and outlet pipe h, h³ having suitable valves (not shown).
The plates a carrying the yarn 6' to be treated in cop or other similar compact
form, are arranged to slide in grooves a¹ furnished with a packing a' and suitably
formed at each end and near the perforated bottom e at a short distance apart from
the pipe orifice g, the latter being furnished in front with deflector plates i, so as to
divide the suction of the circulating pump (not shown) equally over the whole
surface of the plates or carriers a. The upper ends of the latter are supported by
a rim k furnished also with a packing a thus forming chambers 9 between the
plates or carriers a and the sides of the treating tank c. Above the rims / two
other similar rims & m are formed a suitable distance apart from each other and
pipes n & o arranged between the same, communicating with a suction or air pump
(not shown).
The plates or carriers a when lowered into, or lifted out of the treating tank c,
by suitable appliances, bear against the packing a² of the rims k, l, & m, and thus
form each space between, into a comparatively narrow hermetically closed
chamber n', o so as on communication being established between the same,
pipes n, n³ & o, o and the suction or air pump (not shown) respectively, the yarn b²,
is subjected to air exhaustion, and liquor extraction, which owing to the plates or
carriers a being gradually passed over the chambers n', o¹ and the comparatively.
small number of injection tubes or spindles 6 thus brought in communication there-
with successively, requires only a small suction or air pump (not shown), and effects
a more uniform exhaustion of air and extraction of liquor.
The yarn 61 to be treated is subjected to air-exhaustion on the plates or carriers a
being placed into, and on being removed out of the treating tank c to liquor
extraction, whilst when the plates or carriers a are in their lowest position the
yarn 6 can be impregnated with dye or other suitable liquor or gases through the
action of a force or suction pump or pumps (not shown), either with or without
preliminary air exhaustion, or on hermetically closing the treating tank c, through
the combined action of compressed air or steam introduced into the treating tank c
through pipe o o connected with a compressor and a suction pump (not shown) and
finally dryed in the same apparatus by superheated air or steam or other hot gases
if desired, introduced into the treating tank c through pipe o' and permitted to
escape through pipes 9, 9¹.
On hermetically closing the treating tank by means of the lid d the yarn b¹ in
cop or other similar compact form may be dyed or otherwise treated under vacuum
by exhausting the treating tank e of air and afterwards admitting and circulating
the dye or liquor through the same.
In cases where the dye or other liquor is used in a very hot state, air or steam
may be compressed onto the same whereby the action of the circulating pump (not
shown) is assisted and a thorough impregnation of the yarn 6' effected, or suitable
gases may be used only.
In connection with an inlet h¹ and outlet 2 of the treating trank c, we arrange a
number of dye or other liquor supply cisterns (not shown) so as to permit of
readily changing the dye or other liquor at will.
A number of the described apparatus may be arranged in connection with each
-
ปี

page_text: other, so as to perform the various operations simultaneously and thereby save a
great deal of time and labour, which otherwise would be incured in placing on or
removing the cops from the plates or carriers a.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
-claim, is-
An apparatus for dyeing, scouring, bleaching and otherwise treating yarn in
cop or other similar compact form, consisting of a treating tank c, d, having
chambers g³, n', o, and communicating with a suction or air pump and a force pump
and compressor in combination with a suitable number of plates a, carrying on
hollow perforated spindles b the yarn b¹ to be treated, which plates or carriers a
when in position in the tank c, d and liquor, close the said chambers hermetically,
the chamber o¹, by open tank c, during the introduction of the plates or carriers a,
serving to subject the yarn 6' to air exhaustion and the chamber when the plates
or carriers a are in their lowest position to impregnation, by drawing or forcing
liquor or gases through the same, or on the tank e being closed, by the combined
action of a suction pump and air compressor, or by forcing compressed air, gas or
steam through the same, whilst when raising the plates or carriers a the chamber n¹
serves to subject the yarn 6' to liquor extraction, substantially as and for the
purpose set forth.
