Improvements in or applicable to Machines for Dyeing Yarn in the
Form of Cops, Bobbins, or the like.
I, WALTER COVENTRY, of The Elms, Macclesfield, Cheshire, Engineer, do
hereby declare the nature of this invention to be as follows:--
My said invention relates to improvements in machinery or apparatus for dyeing
yarn in the form of cops bobbins or the like shapes.
As applied for instance to the dyeing of cops they are carried by perforated
spindles or the like grooved or perforated devices for permitting the passage
or percolation of the dye liquor through the cop from the interior to the exterior
or vice versa. A suitable carrier box or cylinder is provided with sockets or the
like devices for receiving the ends of the spindles which are secured in their
sockets by a keeping or fastening plate or plates taking over collars or flanges
on the spindles or over the ends of the spindles. In one form the keeping plate
is provided with apertures or perforations of a key-hole like shape larger at one
part than at the other. When the large part of a perforation is opposite a socket
à spindle with its collar or shoulder may be pushed through the keeping plate
into the socket. A slight lateral movement of the keeping plate suffices to bring
the narrow part of the perforation over the shoulder or collar and thus locks the
spindle in the socket.
The carrier box or cylinder is attached to a sleeve (mounted on a central hollow
pillar) by means of suitable lugs or engaging parts which permit of its ready
attachment and detachment from the sleeve. The sleeve is provided with a
stuffing box or other liquid tight packings and is capable of being slid up and
down on the central hollow pillar.
When in use the above mentioned parts are submerged in the dye liquor in a
suitable surrounding receptacle or cistern which I may provide with heating
pipes for the purpose of heating the dye liquor.
The central hollow pillar is perforated and its interior communicates by means
of pipes and suitable connections with a suitable circulating pump or pumps
which are also in communication through other connections or conduits with
the dye liquor receptacle or cistern surrounding the carrier box or cylinder.
By the means above described a constant circulation of dye liquor may be
caused to take place from the cistern through the cops the carrier box the
central pillar and back again to the cistern or vice versa according to the position
of valves which I provide for directing or reversing the direction of the flow or
according to the direction in which the pump or pumps cause the liquor to
circulate.
When the cops have been subjected for the necessary length of time to the
action of the dye liquor the carrier box or receptacle is slid up the central
pillar and is thus lifted out of the dye liquor while any liquor remaining in
the carrier box runs through the perforated central pillar into the circulating
system.

page_text: In the interior of the central pillar I provide an air pipe communicating with
a suitable air pump.
While the dyeing operation is proceeding the air pipe in
the central pillar is closed by a plug or valve, which is withdrawn or opened
when the carrier box or cylinder is elevated so that the air pump is then in
communication with the interior of the carrier box or cylinder and air may be
sucked or forced through the cops.

Improvements in or applicable to Machines for Dyeing Yarn in the
Form of Cops, Bobbins, or the like.
I, WALTER COVENTRY, of The Elms, Macclesfield, Cheshire, Engineer, 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:-
My said invention relates to improvements in machinery or apparatus for dyeing
yarn in the form of cops bobbins or the like shapes by the percolation (produced
by pressure or vacuum) of dye liquor.
In order to more clearly set forth my said invention I will describe it with
reference to the accompanying drawings of which
Figure 1 is a sectional elevation.
Figure 2 is a plan. .
Figure 3 is an elevation of one form of keep plate.
In all the figures the same letters refer to the same parts.
Taking cop dyeing as an instance of the application of my said invention
the cops a (one only of which is shown) are carried by perforated spindles a¹ or
the like grooved or perforated devices for permitting the passage or percolation
of the dye liquor through the cop from the interior to the exterior or vice versa.
A suitable carrier box or cylinder bis provided with sockets or the like devices
for receiving the ends of the spindles which are secured in their sockets by a
cylindrical keep or fastening plate or plates taking over collars or flanges on
the spindles or over the ends of the spindles. When applied to the ends of the
spindles the keep plate c is conveniently made in halves (Fig. 2) which are
secured to each other against the ends of the spindles by bolts which are
hinged to lugs on one half and take into slots in lugs on the other half the
whole being tightened by nuts The two halves of the keep plate are carried
by arms e. When applied to the inner ends of the spindles the cylindrical keep
plate (indicated by dotted lines at in Fig. 1) is provided with apertures or
perforations of a key-hole like shape larger at one part than at the other
(Fig. 3). When the large part of a perforation is opposite a socket a spindle with
its collar or shoulder may be pushed through the perforation of the keep plate
into the socket. A slight rotation of the keep plate c³ suffices to bring the narrow
part of the perforation over the shoulder or collar and thus locks the spindle
in the socket.
The carrier box 6 or cylinder is attached to a sleeve d (mounted on a central
hollow pillar) by means of suitable lugs or engaging parts such as 62 which permit
of the ready attachment and detachment of the carrier box from the sleeve. The
conical upper flange of the sleeve is slotted in one or more places as at d¹ to

page_text: permit the passage of the lug 62 when the carrier box bis dropped down on the
sleeve d. A slight turn of the carrier box brings the projecting part of the lug b
under the plain part of the flange. An inclined surface on the lug 63 bearing
on the underside of the flange as it is turned aids in making a tight joint between
the two conical surfaces of the carrier box and the sleeve."
The sleeve d has a metallic or other liquid tight packing d² or a stuffing box
and is capable of being slid up and down on the central hollow pillar e by
hooks engaging with the lifting arms d³ and connected to an overhead crane or
other suitable lifting device.
When in use the above mentioned parts are submerged in the dye liquor in a
suitable surrounding receptacle or cistern f which I may provide with heating
pipes for the purpose of heating the dye liquor.
The central hollow pillar is perforated as at e¹ and its interior communicates by
means of pipes e² and suitable connections with a suitable circulating pump or
pumps which are also in communication through other connections or conduits e³
with the dye liquor receptacle or cistern surrounding the carrier box or cylinder.
By such means a constant circulation of dye liquor is caused to take place from
the cistern through the cops the carrier box the central pillar and back again
to the cistern or vice versa according to the position of valves which may be used
for directing or reversing the direction of the flow or according to the direction
in which the pump or pumps cause the liquor to circulate.
When the cops have been subjected for the necessary length of time to the
action of the dye liquor the sleeve d and with it the carrier box or receptacle
is slid up the central pillar e and is thus lifted out of the dye liquor while any
liquor remaining in the carrier box runs through the perforated central pillar "e
into the circulating system.
In the interior of the central pillar I provide an air pipe g communicating with
a suitable air pump. While the dyeing operation is proceeding the air pipe in
the central pillar is closed by a valve being pressed against the top of the
air pipe by a buffer spring and spindle g³ mounted in a socket depending from
the valve. On the carrier box lifting the pressure will be taken off the spindle g³.
Then when the sleeve d has nearly completed its upward stroke it meets one or
more projections g from the valve and lifting the latter establishes communica-
tion between the interior of the pipe and the interior of the carrier box b
Air may then be forced or sucked through the cops (while elevated clear of the dye
liquor) according to the direction in which the air pump may be worked.
An air valve is provided for controlling the admission and escape of air when
the carrier box is being raised or lowered.
I am aware that the system of dyeing yarn in a wound state by percolation is
already in use and also that various methods of producing the circulation of the
dye liquor by means of pumps and the like are well known and I wish it to be
clearly understood that I make no broad claim to such and that my said invention
is strictly limited to improved means for practising such systems and methods.
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. The improved apparatus for dyeing yarn by percolation substantially as
hereinbefore described and shown.
2. In apparatus for dyeing yarn in a wound state by percolation and circula-
tion the combination of a dye cistern f a central pillar e and a carrier box b
adapted to slide up and down on the central pillar e substantially as and for the
purpose set forth and shown.
3. In apparatus for dyeing yarn by percolation the combination in a dye cistern
of an air pipe g a perforated pillar e a sliding sleeve da carrier box 6 detachably
mounted thereon substantially as and for the purpose set forth and shown.
4. In apparatus for dyeing yarn by percolation the combination with an air

page_text: pipe and a rising and falling carrier box of an air valve to automatically open
when the carrier box rises substantially as and for the purpose set forth and
shown.
5. In apparatus for dyeing yarn by percolation the combination with sockets
or the like for holding the spindles of a cylindrical keep plate having perforations
for permitting the insertion and securing the spindles in their sockets substantially
as and for the purpose hereinbefore set forth and described with reference to
Fig. 3 of the accompanying drawings.
6. In apparatus for dyeing yarn by percolation the combination with sockets
or the like for holding the spindles of a cylindrical keep plate or jacket taking
over and bearing against the points of the spindles substantially as described
and set forth.
