Improvements in Machines for Dyeing, Bleaching, and otherwise
Treating Yarn in Cops or Bobbins.
We SAM MASON, junior, of St. Annes Place, Manchester, Engineer, and WILLIAM
THOMAS WHITEHEAD of 49 Spring Lane Radcliffe, Engineer, both in the County of
Lancashire, do hereby declare the nature of this invention to be as follows:—
Our invention relates to that class of machines or apparatus used in dyeing,
bleaching, scouring, and otherwise treating yarns of cotton, silk, wool, worsted, or
other animal or vegetable fibres, in the form of cops or bobbins, or in a similar
compact form, where they are mounted on perforated tubes, skewers or spindles, and
the dye or other liquid, is drawn or forced through the same by suitable means.
This invention has principally for its object to provide means whereby the capacity
of the class of machines or apparatus aforesaid, as regards quality and quantity of
cops or bobbins treated thereby, is increased, its construction simplified, and made
less liable to repairs, and more easy for operation, than heretofore has been the case.
The invention consists in the first place in the combination of a vertically sliding
hollow cop carrier or table, formed with a conduit or pipe, which cop carrier or table
is suitably suspended from the framework of the machine, with a liquid tank, arranged.
below the said cop carrier or table into and out of which tank the said cop carrier or
table can be raised or lowered, respectively.
Second, in the combination with the aforesaid cop carrier or table, of a cylinder
fixed to the said framowork, in which the aforesaid conduit or pipe is permitted to
slide vertically and made tight by means of a stuffing box.
Third, in the combination of the aforesaid cylinder, with a conduit or pipe, pro
on each side of its connection with the said cylinder, respectively, with a valve, one
end of the said conduit or pipe being in communication with a liquid circulating
pump and the other end with a vacuum chamber or source, each of which, by
means of a suitable pipe, is also brought in communication with the aforesaid liquid
tank.
Fourth, in the combination with the aforesaid cop carrier or table, of a removable
cover which can be lowered onto or raised from the said cop carrier or table, and is
furnished at its top with inlet valves, and a distributing plate below the same.
To this end we employ a table or cop carrier cast hollow, its face being formed
with perforations into which are fixed the perforated tubes, skewers or spindles,
carrying the cops to be treated, either directly, by providing the lower end of the
perforated tube, skewer, or spindle, underneath its flange, with an india-rubber ring,
to ensure a tight fit, or indirectly, by fitting hollow nipples into the perforations, on
which nipples the perforated tubes, skewers, or spindles, carrying the cops, are
placed.
The aforesaid cop carrier or table we forin or furnish with a conduit or pipe fitted
to and in communication with the hollow part of the cop carrier or table, sliding
through the stuffing box in the aforesaid cylinder, & depending from the framework
of the machine.
The cop carrier or table is arranged to be raised or lowered into the liquid tank
on the framework, preferably by means of the racks fixed thereto, suitably guided and
in gear with pinions keyed on a shaft, suitably mounted on the framework of the
machine.
Rotary and reversible motion is imparted to the aforesaid shaft preferably from
the driving shaft of the machine, by means of worm wheel gearing, pullies, and
crossed and open straps, the reversing or stoppage of the rotation of the said shaft

page_text: and descent or ascent of the cop carrier or table, being effected automatically by
means of an arm fixed adjustably on to one of the said racks or rods, which at the
desired time, and alternately, comes into contact with two levers connected together
by means of a rod, and actuating the strap fork in connection with the aforesaid
open and crossed straps.
To the aforesaid cylinder is connected a conduit or pipe which is furnished on
each side of its connection therewith, with a valve, leading respectively to a circulating
pump and vacuum chamber.
The latter may either be connected to a vacuum pump or the condenser of a
steam engine where such is convenient, or other vacuum source by means of a pipe
fitted to its top, the bottom thereof being furnished with a pipe and tap, in commu-
nication with the liquid tank, the vacuum chamber serving also to receive any liquid
drawn from the cops at intervals, and return the same to the liquid tank.
The operation of the machine is conducted as follows:-
The cop carrier or table when out of the liquid tank is supplied with cops and
then lowered into the liquid necessary for the intended treatment, contained in the
tank.
The valve leading to the circulating pump is opened and the latter set in motion,
the liquid is then drawn through the cops, into the hollow part of the cop carrier or
table, up its conduit or pipe, through the cylinder in communication therewith and
its conduit or pipe leading to the circulating pump and returned by the latter, and
pipe connected therewith, to the liquid tank.
The operation is now finished, the aforesaid valve is closed, the cop carrier or table
raised by means of the said racks and pinions out of the liquid tank, and the valve
leading to the vacuum chamber is now opened, and the vacuum pump set in motion
to extract the liquid from the cops, after which the machine is ready for another
charge of cops to be treated.
If desired to treat cops under vacuum, a cover is used in connection with the cop
carrier or table:
This cover consists of a hollow body, made in shape to correspond with the con-
figuration of the cop carrier or table, the edges being formed V shaped to drop and
fit into grooves formed in the face of the cop carrier or table and fitted with rubber
rings.
By these means and the employment of wing nuts and bolts the said cover can be
fixed hermetically to the cop carrier or table, the cover inside being furnished with
a perforated disc, which serves to distribute the liquid over the cops, which liquid is
permitted to enter the cover when the cop carrier or table, and cover hermetically
fixed thereto, are in the liquid tank, by opening valves arranged on the top of the
cover.
The latter is arranged to be raised from and lowered onto the said cop carrier or
table preferably by means of a chain running over pullies and fitted with balance
weights.
When working under vacuum the operation is conducted as follows:
-
The cop carrier or table is charged with cops and the aforesaid cover lowered and
secured thereto as described.
The valve in communication with the vacuum chamber is then opened, and the
vacuum pump set in motion.
After obtaining a vacuum, the said valve is closed and the covered cop carrier or
table lowered into the liquid in the tank.
The valves of the said cover are then opened and the liquid is immediately permitted
to flow into the same, onto the aforesaid plate which distributes the liquid onto the
cops, and so saturates the same.
Simultaneously with this operation the valve leading to the circulating pump
is opened, the latter set in motion and the treatment continued as before
described.
In treating wool cops the cop carrier or table may be raised and lowered as often
as required until the desired shade is obtained.

page_text: Instead of employing only one of the described machines two may be connected
together and worked alternately by suitably arranging the valves and pipes in connec-
tion with the circulating pump and liquid tank.

Improvements in Machines for Dyeing, Bleaching, and otherwise
Treating Yarn in Cops or Bobbins.
We SAM MASON, junior, of St. Anne's Place, Manchester, Engineer, and WILLIAM
THOMAS WHITEHEAD of 49 Spring Lane, Radcliffe, Engineer, both in the County.of
Lancashire, 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 :-
Our invention relates to that class of machines or apparatus used in dyeing, bleaching,
scouring, and otherwise treating yarns of cotton, silk, wool, worsted, or other animal
or vegetable fibres, in the form of cops or bobbins, or in a similar compact form,
where they are mounted on perforated tubes, skewers or spindles, and the dye or
other liquid is drawn or forced through the same by suitable means.
This invention has principally for its object to provide means whereby the capacity
of the class of machines or apparatus aforesaid, as regards quality and quantity of
cops or bobbins treated thereby, is increased, its construction simplified and made less
liable to repairs, and more easy for operation, than heretofore has been the case.
And in order that our invention may be more fully understood we have caused to
be appended hereunto two sheets of drawings marked with letters of reference indi-
cating like parts in the various figures.
Fig. 1 Sheet I is a side elevation of the apparatus showing the cop table and cover
partly in section. Fig. 2 Sheet II is a side elevation of a modification of the same.
In carrying out our invention and referring to Fig. 1, the improvements consist in
the first place in the combination of a vertically sliding hollow cop carrier or table a,
formed with a conduit or pipe b, which cop carrier or table a is suitably suspended
from the framework c of the machine, with a liquid tank d, arranged below the said
cop carrier or table a, into and out of which tank, the said cop carrier or table a can
be raised or lowered, respectively.
Second in the combination with the aforesaid cop carrier or table a, of a cylinder e
fixed to the said framework c, in which the aforesaid conduit or pipe b is permitted to
slide vertically, and made tight by means of a stuffing box el.
Third, in the combination of the aforesaid cylinder e, with a conduit or pipe f,
provided on each side of its connection with the said cylinder e, with a valve g, hone
end of the said conduit or pipe f being in communication with a liquid circulating
pumpi, and the other end with a vacuum chamber or source k, each of which by
means of a suitable pipe 1, 1, is also brought in communication with the aforesaid
liquid tank d.
Fourth, in the combination with the aforesaid cop carrier or table a, of a removable
cover m which can be lowered onto or raised from the said cop carrier or table a and
furnished at its top with inlet valves n & n' and a distributing plate to¹ below the
same.
To this end we preferably employ a table or cop carrier a cast hollow, its face
being formed with perforations a' into which are fixed the perforated tubes, skewers;
or spindles o carrying the cops o¹ to be treated, either directly, by providing the
lower end of the perforated tube, skewer, or spindle o, underneath its flange, with an
india-rubber ring, to ensure a tight fit, or indirectly, by fitting hollow nipples into
the perforations, on which nipples the perforated tubes, skewers, or spindles o carrying
the cops o' are placed.
The aforesaid cop carrier or table a we form or furnish with a conduit or pipe b

page_text: fitted to and in communication with the hollow part a² of the cop carrier or table a,
sliding through the stuffing box e¹ in the aforesaid cylinder e, and depending from the
framework c of the machine. The cop carrier or table a is arranged to be raised or
lowered into the liquid tank d preferably by means of the racks p fixed to the cop
carrier or table a, suitably guided and sliding in the framework c and in gear with
pinions 9 keyed on a shaft r, mounted in bearings on the framework c of the
machine.
Rotary and reversible motion is imparted to the aforesaid shaft preferably from
the driving shaft s mounted in bearings s' fixed to the framework c of the machine, by
means of a worm wheel t fixed on the shaft r, to which is. geared the worm t¹ fixed.
on the shaft s.
Motion is imparted to the lattor reversibly by means of pullies s¹ fixed thereon, and
pullies u fixed on the second motion shaft u¹ of the pump i, and crossed and open
straps &. The reversing or stoppage of the rotation of the shaft and descent
or ascent of the cop carrier or table a is effected automatically by means of an arm v
fixed adjustably onto one of the said racks or rods p, which at the desired time and
alternately comes into contact with two levers p', fixed onto studs p² mounted on the
framework c.
These levers are connected together by means of a rod p³, the stud p² of the upper
one having attached a strap fork p₁ which actuates the aforesaid open and closed
straps,
To the cylinder e is connected a conduit or pipe f which is furnished on each side
of its connection therewith, with a valve g & leading respectively to a circulating
pump and vacuum chamber k.
The latter. may either be connected to a vacuum pump or the condenser of a steam
engine where such is convenient, or other vacuum source by means of a pipe ¹ fitted
to its top, the bottom thereof being furnished with a pipe and tap k², in com-
munication with the liquid tank d, the vacuum chamber serving also to
receive any liquid drawn from the cops at intervals, and return the same to the
liquid tank d.
The operation of the machine is conducted as follows:-
The cop carrier or table a when out of the liquid tank d' is supplied with cops
and then lowered into the liquid necessary for the intended treatment contained in
the tank d.
The valve leading to the circulating pump i is opened and the latter set in motion,
the liquid is then drawn through the cops, into the hollow part a² of the
cop carrier or table a, up its conduit or pipe b, through the cylinder e in
communication therewith, and its conduit or pipe f leading to the circulating
pump i, and returned by the latter, and pipe 1 connected therewith, to the liquid
tank d.
The operation is now finished, the aforesaid valve g is closed, the cop-carrier or
table a raised by means of the said racks p and pinions q out of the liquid tank d,
and the valve leading to the vacuum chamber k is now opened and the vacuum
pump.set in motion to extract the liquid from the cops, after which the machine is
ready for another charge of cops to be treated.
:
If desired to treat.cops under vacuum, a. cover m is used in connection with the cop*
carrier or table a..
This cover consists of a hollow body, made in shape to correspond with the
configuration of the cop carrier or table a, the edges being formed V shaped to drop
and fit.into grooves w formed in the face of the cop carrier or table a and fitted with
rubber rings.
By these means and the employment of wing nuts and bolts the said cover can be
fixed hermetically to the cop carrier or table a, and is inside furnished with a
perforated disc w³, which serves to distribute the liquid over the cops, which liquid
is permitted to enter the cover m. when the cop carrier or table a and cover m
hermetically fixed thereto, are in the liquid tank d, by opening valves n, n' arranged:
on the top of the cover m.
•

page_text: The latter is arranged to be raised from and lowered onto the said cop carrier or
table a preferably by means of a chain running over pullies fitted to the frame-
work c and provided with balance weights.
When working under vaccum the operation is conducted as follows:-
The cop carrier or table a is charged with cops and the aforesaid cover m lowered
and secured thereto as described.
The valve in communication with the vacuum chamber k is then opened and the
vacum pump set in motion.
After obtaining a vacuum, the said valve is closed and the covered cop carrier or
table a lowered into the liquid in the tank d.
The valves n of the said cover m are then opened and the liquid is immediately
permitted to flow into the same, onto the aforesaid disc w' which distributes the liquid
onto the cops, and so saturates the same.
Simultaneously with this operation the valve leading to the circulating
pump is opened, the latter set in motion and the treatment continued as before
described.
In treating wool cops, the cop carrier or table may be raised and lowered as often
as required, until the desired shade is obtained.
Instead of employing only one of the said machines two may be connected
together and worked alternately by suitably arranging the valves and pipes in
connection with the circulating pump i and liquid tank d.
In order to prevent the liquid in the tank d from being agitated by the returned
liquid, we furnish the tank d inside with a division d' see Fig. 1.
Referring to Sheet II, Fig. 3 represents a modification of our invention and
consists in admitting the liquid to the cop carrier or table a from below instead of
from above thereof. To this end the conduit or pipe b is connected to the bottom of the
cop carrier or table a and the cylinder e in which it slides and to which the pipe fis
connected is fitted through the bottom of the liquid tank d, Fig. 3, Sheet II also
illustrates the use of the machine for dyeing or otherwise treating wool tops e³ which
are placed on perforated tubes es provided with a perforated bottom e and fixed
into the cop carrier or table a and used with or without the cover m shown in
Fig. 1.
The lifting and lowering of the cop carrier or table a and action of the
liquid pump & vacuum chamber k remains the same as herein before described.
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 :-
In machines for dyeing, bleaching and otherwise treating yarn in cops or other
compact form :—
1st. The general combination, contruction and adaption of parts with reference to
the annexed drawings operated substantially as and for the purposes specified.
2nd. The vertically sliding hollow cop carrier or table a capable of being lowered
into and raised out of a liquid tank d by suitable means and of being brought into
communication with a liquid pump i and vacuum chamber or source k substantially as
and for the purpose specified.
3rd. The combination with the hollow cop carrier or table a of a removable cover m
furnished with valves n aud n¹ and capable of being secured hemetrically unto the cop
carrier or table a and raised therefrom by suitable means substantially as set forth
and for the purpose specified.
