RESERVE
Wo, ELY SUTCLIFFE, and GEORGE EDWARD SUTCLIFFE, of Mirfield, Yorkshire,
Cotton Spinner, do hereby declare the nature of this invention to be as follows:-
Our Invention consists in a new means or method of bleaching, damping, and
dyeing, loose fibre, yarns, threads or other fibrous materials.
In carrying out our Invention we place the material to be dyed into a bag or net
through the centre of which is a perforated pipe:-The bag or net is then taken and
placed into a cage, capable of rotating within a suitably shaped vessel. A supply
pipe is now placed in connection with the central perforated pipe and the cage and
outer vessel closed. After the cage is set in motion, water is supplied to the
perforated pipe, the centrifugal action thereof forcing the said water through the
fibre until it is saturated and ready to take in the dye liquor which is now supplied
to the perforated pipe and forced through the fibre by centrifugal action and dyed
thereby: When the fibre or fabric has been thus dyed, the dye liquor is turned off
and the speed of the cage increased so as to dry the dyed material, the operations of.
saturating, dyeing, and drying may be performed without removing the bag from the
cage.
This method of dyeing is very effective as the centrifugal action of the cage opens
and loosens the fibre, making it into a fit condition to receive the dye liquor.
The water or liquor forced through the fibre, passes out of the cage and lodges in
the bottom of the outer vessel, and may be reused again.
This method of dyeing can be advantageously used for dyeing slivers of fibre, as
the bag may be placed into the coiler of a carding or other machine and the sliver
ги

manner already described, and this can be done without disturbing the position of the
coiled sliver, which may be taken back to a drawing frame or other machine following
that which it left where the operations of preparing and spinning are completed, so
as to produce colored yarn, instead of dyeing in the bank as at present.
Instead of the loose fibre being placed into a bag it may be placed direct into the
rotary cage.
To bleach the fibre or fabrics, they are placed into the bag or cage, and soda,
chlorine, or other suitable bleaching solutions, forced through to the fibre in the same
manner as water, or dye liquor.

Improvements in the Method of and Apparatus for Bleaching,
Damping, and Dyeing Loose Fibre, Yarns, Threads, or other
Fibrous Materials.
We, ELY SUTCLIFFE and GEORGE EDWARD SUTCLIFFE, of Mirfield, Yorkshire,
Cotton Spinners, 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 and accompanying drawing :—
Our Invention relates to the bleaching, damping, and dyeing of loose fibre, sliver,
yarns, threads, and other fibrous materials. In carrying our invention into effect we
place the material to be treated within a cage provided with a central perforated tube
and capable of being rotated within a suitably shaped vessel or we enclose the
materials within a bag or envelope which is provided with a perforated tube and
place the bag with its contents in the said cage. A supply pipe is placed in
connection with the central perforated pipe and water or liquor is supplied to the
perforated pipe whilst the cage is revolving. When the materials have been
sufficiently treated the supply of liquid is stopped and the speed of the cage is
increased so as to dry the material or to discharge the excess of liquid therefrom.
Our Invention can be advantageously used in the dyeing of slivers of fibre, as a bag
may be placed in the coiler of a carding ongine or other machine and the sliver be
coiled into such bag, which can be placed with its contents in the rotary cage and the
sliver whilst in its coiled condition be dyed.
The accompanying drawing represents a vertical section of a machine suitable to be
used in the carrying into effect of our invention. In the said drawing a is the said
cage and b is the inner or central perforated tube. The said cage is mounted to
revolve within a chamber c which may be cylindrical in cross section or be rectangular
or of any suitable form and in some cases may be sufficiently large to contain two
or more of the cages. The shell of the said cage is perforated for the passage of
liquid or is made of wire gauze or is otherwise made of a suitably pervious material.
The bottom a¹ of the cage is fixed or formed upon a hollow shaft which passes
through a chamber d into which water dye liquor or other liquid used in the treatment
of the materials is admitted or can be forced through a supply pipe e.
Such liquid
passes through holes in the said hollow shaft and rises into the perforated tube b.
The shaft is extended in a solid form through a packed gland at and is provided
with a bevel wheel 9 which gears with a wheel which is upon a cross shaft which
can be caused to revolve by means of a driving helt acting upon a pulley i. The
materials to be treated are placed within the cage and packed around the tube 6 or a
bag or envelope containing the materials is placed within the cage. When operating
according to the latter method the perforated tube 6 is placed or fixed in position
within the said bag or the bag is provided with a perforated tube and when the bag
is filled the contents are packed or arranged around the said tube and the bag is
introduced into the cage in such a manner as that the perforated tube shall communi-

page_text: cate with the passage through the hollow shaft which passes through the chamber d.
In the example the cago is provided with a cover which is placed in position after
the cage is charged and is held down by means of a screw / which works in a nut in
a hinged cross bar m which can be brought over the mouth of the cage and be
secured by means of a clamp n. The end of the said screw also acts to steady the
upper end of the cage during its revolution. For this purpose the end of the screw
may enter a recess or bearing at o. The method of closing the upper end of the cage
may be varied and if preferred a close fitting cover may take the place of the cross
bar m. In using the apparatus-say for example in the dyeing of textile material-
the cage having been charged and set in motion water is admitted by the pipe e or is
forced through the said pipe and thereby into the tube b from which it passes through
the perforations into and through the mass of materials being finally discharged
through an outlet pipe p. The pipes e and p are supposed to be suitably connected
with the vats or cisterns containing the dye fiquor and with a water supply pipe cocks
or valves regulating the supply and enabling either water or dye liquor to be admitted
as required but it has not been considered necessary to show the arrangements for
such supply as they would vary according to circumstances. When the materials
have been wetted the water is shut off and dye liquor is admitted in its place.
Previously to the inlet of the dye liquor the cage may be rapidly revolved to discharge
the excess of water suitable driving arrangements for varying the speed of the cage
being provided. The dye liquor is passed through the materials in the same manner
as the water until it is considered that the operation is completed. The cage is again
revolved rapidly to discharge the excess of dye liquor. This rapid revolution may be
continued as long as is considered to be desirable so that the materials may be dried
or freed from excess of moisture to a greater or lesser extent by the centrifugal force.
This centrifugal force also aids in passing the water or liquor through the mass of
materials and tends to the obtainment of greater uniformity in the result. As has
been hereinbefore mentioned when operating upon sliver we may coil the sliver in a
bag but we prefer to form the sliver into a package in accordance with improvements
in our present invention for which improvements we have made application for
Letters Patent such application bearing the number 14971 of the year 1886. We
have also improved the method of mounting the revolving cage whereby we obtain
increased steadiness during revolution and also a better distribution of the water or
liquor. We do not confine ourselves to the vertical arrangement of the axis of the
cage.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim is:
(1) The combination of parts constituting the machine substantially as and for the
purpose set forth and indicated hereinbefore and by the accompanying drawings.
(2) The perforated cage mounted to be revolved and provided with an inner
perforated tube through which liquids can be passed into and through fibrous
materials with which the cage is charged substantially as and for the purpose set
forth and indicated.
(3) The method of dyeing sliver or other fibrous material wherein such material
is placed coiled or packed around a perforated tube within a cage which is revolved
whilst the dyeing liquor is passed through the said perforated tube and thereby
through the mass of material and which can be revolved to discharge the excess of
such liquor or to partially dry the said material.
