PROVISIONAL SPECIFICATION.
A New or Improved Machine for Dyeing One or More Warps.
I, EDWIN BROOK of Slaithwaite Dye Works, Slaithwaite near Huddersfield,
Yorkshire, Dyer do hereby declare the nature of this invention to be as follows :-
:-
This invention refers to a new or improved machine for dyeing warp or warps,
my object therein being to provide means whereby the whole length of a warp or
warps may be treated at one time, and a more even and level colour produced
throughout the fibre than is obtainable by the present method of treatment, and in
less time.
In order to carry out my invention 1 employ any suitable description of dye vat
or cistern within which are supported on a cross shaft, two or more wheels or discs
of equal diameters. At a given distance from the centre of the said wheels and
radially of their centres, are bars or rods secured at each end to the wheels, the
upper or outer surfaces of such bars being curved or rounded. One end of the
warp is made secure to one of the cross bars and a slow motion being given by
worm gearing, to the shaft and wheels, the warp is wound onto each cross bar
successively until it reaches the first named bar when it is guided to one side of
the warp already thereon and wound upon the other cross bars in like manner, this
being continued, every revolution, until the warp has been wound upon the whole
length of the cross bars bobbinwise. When this has been done the attendant
introduces a short distance above each fixed cross bar and in the same radial lines,
other cross bars having curved surfaces terminating at one side in feather or
rounded edges, such bars being provided at each end with shafts or studs which
pass through corresponding openings in the web of each wheel forming journals
for said shafts or studs. The unwound warp is now transferred to the second
series of cross bars upon which it is wound in the same manner as above set
forth, and when filled, another series of cross bars are introduced above those last
inserted, this being repeated until the whole length of warp is wound upon the
machine, any number of cross bars, within the limits of the diameters of the wheels
or discs, being used. The studs or shafts projecting from one end of the cross
bars engage with lever arms or suitably pivotted levers or rods on the outside of
the wheel, each radial series being coupled together and operated in such manner
as to cause the cross bars in each said series to simultaneously oscillate upon their
fulcrums or studs as and for the purposes hereafter explained.
The cross bars nearest the centre of the shaft carrying the wheels do not require
to be oscillated and are therefore preferably fixed in the machine.
The rotary motion of the machine is reversed for the purpose of dyeing the
warp, the whole of which is passed through the liquor in the dye vessel at every
revolution of the wheels, only the lower half or portion of the warp however being
in the liquor at one time.
At a suitable position in the machine are cams or cam surfaces or similar devices
or mechanism with which the couplings connecting each radial series of levers or
rods on the ends of the cross bars, engage, or by which they are forced endwise in
such manner as to tilt or oscillate the cross bars whose feather or round edges
are thereby brought against the warp on the cross bars immediately below, the
action being somewhat similar to the closing of louvres one upon the other. This
action is timed to take place just before the cross bars emerge from the dye liquor
and is for the purpose of gripping or holding the portion of warp between one
radial series of cross bars and another series, so that when the warp comes out of
the liquor it is prevented from becoming slack by reason of the weight of the
liquor which it carries, whereby felting and entangling of the warp is prevented

page_text: and a better result is obtained. At or about the same time as the series of bars
just emerging from the liquor are caused to grip the warp, the preceding series are
oscillated or moved back again to their normal positions so as to release the warp,
by means of springs or by similar mechanism to that which closes the bars upon the
warp, each radial series of bars being operated in both directions at every revolu-
tion of the wheels. Instead of lever arins, levers, or rods, and cams or cam
surfaces being employed to oscillate the cross bars, I may place pinions on the
ends of the cross bars gearing into each other, and partially rotate them at the
time and in the direction required by racks suitably attached to the machine, but
it is obvious that various mechanical devices could be employed which would give
the same results.
For the purpose of treating a much larger quantity of warp at one time and in
one machine, I may secure two, three or more sets of wheels or discs to frames
mounted upon a central shaft, which on being rotated would carry each set of
wheels or discs with their arrangement of cross bars, and the warp wound thereon,
successively through the liquor once every revolution. Each set of wheels with
cross bars would hold-say-one warp, and thus two, three or more warps would
be dyed at the same time. Each radial series of cross bars in each set of wheels
would be operated in like manner as if one set of wheels only were employed. The
sets of wheels may be slowly rotated by chain and chain wheels or by other system
of gearing, independently of the rotation of the frames carrying such wheels.

COMPLETE SPECIFICATION.
A New or Improved Machine for Dyeing One or More Warps.
I, EDWIN BROOK, of Slaithwaite Dye Works, Slaithwaite, near Huddersfield,
Yorkshire, Dyer, 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 :-
This invention refers to a new or improved machine for dyeing warp or warps,
my object therein being to provide means whereby the whole length of a warp or
warps may be treated at one time and a more even and level colour produced
throughout the fibre than is obtainable by the present method of treatment and in
'less time.
For the purpose of more fully explaining my invention reference is herein had
to the accompanying sheets of drawings wherein
Fig. 1 is longitudinal sectional elevation taken on line 1, 1, of Fig. 2 of my
improved machine, and
Fig. 2 is end elevation of same partly in section looking in the direction of
arrow 2.
.
Figs. 3, 4, and 5 are details of some of the parts hereinafter referred to.
A represents the vessel or cistern for containing the dyeing or scouring liquor
which is introduced at a and passes through the orifice into the vessel. B is the
main driving shaft which is supported in bearings B₁ and communicates rotary
motion by means of worm and wheel to the cross shaft C supported in pedestals at
each side of the vessel. Mounted on the shaft C are two wheels on discs D, D',
provided or east with radial arms E, E', secured at each end to corresponding
arms E, E', are plates or bars c having their longitudinal edges curved or rounded,
said plates being either removeable or fixed and the series forming a core or barrel
around which the warp is first wound, the end of the warp being tied or otherwise
made secure to a rod or device y near the centre of the machine, and the machine
rotated in the direction of arrow 3 for the purpose of winding-on. At the com-
mencement of the second and subsequent revolutions of the machine, the warp is

page_text: guided to one side of that already wound on until the plates are covered from end
to end, whereupon the attendant introduces in the same radial lines a second series
of plates or bars d also provided longitudinally with curved or rounded edges onto
which the warp is now transferred and wound around the series in the same manner
as before explained until the plates are covered from end to end when a third
series d is introduced and so on until the whole length of the warp is wound onto
the machine.
The plates or bars d are provided at one end with studs e which enter corre-
sponding openings el in the radial arms or web of the wheel D' and engage with flat
springs covering said openings, such springs allowing the studs to be pushed
through the openings a sufficient distance to allow the flattened or angular projec-
tions g at the opposite ends of the plates to enter corresponding recesses formed in
the heads of the studs which latter pass through openings in the web or
arms E of the wheel D forming bearings therefor, as shewn clearly in Fig. 3, the
pressure of the springs against the studs e holding the plates in position and
preventing accidental displacement. This method of attaching or supporting the
cross plates enables thein to be oscillated so as to close one upon the other after
the manner of louvres by the oscillation of the studs i and to effect this movement
of the plates I secure short lever arms m on the ends of the studs i and couple
each radial series of levers together by links n connected at their inner ends by
pins o to rods p carrying small pulleys at their extremities which said pulleys engage
with a cam F bolted to the side of the cistern or vessel. The rods p are adapted
to slide in ways formed on the outer face of the wheel D and when winding on
the warp I preferably disconnect the said rods from the links n by removing the
pins o which are inserted through openings t in the inner lever arms and radial
arms or web of the wheel D so that the parts are held rigid and cannot be
oscillated during the time occupied in winding on the warp.
When the warp has been wound around the several series of cross plates or
bars c, d, as indicated by the dotted lines G in Fig. 1 the pins o are withdrawn
from the openings t and re-inserted so as to couple together the links n and rods p,
and the machine is then set in motion and rotated in the direction of arrow 4
or in a reverse direction to that for winding on the warp and preferably at a
slower rate of speed, any suitable speed gearing being employed to give the two
speeds.
As the wheels or discs D, D', rotate, the cross bars or plates in each radial
series are oscillated so as to close one upon the other and to open out again once in
every revolution by means of the cam F which causes the rods p and links n to
be forced from the centre outwards just before their corresponding radial series of
cross plates d emerge from the liquor and close said plates one upon the other as
shewu at H in Fig. 1, and to be brought back again to their normal positions to open
out the plates d at or about the same time as the next succeeding radial series of
cross bars d are caused to close upon each other.
C
In closing the plates upon each other as described, the warp is nipped or held
between the rounded longitudinal edges of the plates d and plates of the radial
series so that as it emerges from the liquor in the vessel it is not dragged down
and unduly slackened by the added weight of the liquor in the fibre, whereby
felting or entangling of the ends of warp is obviated.
The rotation of the machine causes the warp to be carried through the liquor
and exposed to the atmosphere at every revolution.
I find during the process of dyeing that the warp slightly shifts its position on
the edges of the plates or bars and thus exposes each portion of the warp to the
action of the liquor.
w are guards for preventing the warp from slipping off the ends of the cross
plates c, d.
Instead of the cam F being placed centrally of the machine, cam surfaces may
be attached to the side of the cistern so as to act on the outer ends of the links n;
or I may oscillate the cross plates d by means of pinions operated by engagement

page_text: with racks or teeth attached to or formed on the sides of the cistern, it being
obvious that various mechanical contrivances can be applied to oscillate the cross
plates d in the manner set forth in this Specification.
Fig. 4 illustrates clearly the form of cross plate d I employ in the machine, and
shews each end of same.
Fig. 5 shews the head on the end of stud i and recess therein for receiving the
flattened projection on the right hand end of plate d.
For larger quantities of warp I may combine two or more sets of wheels or
discs D, Di, in one machine, and the number of cross plates d in each radial series
may be increased or reduced to suit the size of machine required.
A semicircular cover or top may be provided so as to enclose the machine and
doors or suitable openings made therein to give access to the parts.
a are steam pipes for heating the liquor in the vessel A.
The machine hereinbefore described can be used both for dyeing and scouring
warps which processes are accomplished with less labour and in less time in said
machine than in the present method.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be carried into effect, I declare that
what I claim is -
1
Firstly. The machine, consisting of a central shaft, with discs or wheels D, D',
mounted thereon and capable of rotating partly in and partly out of the liquor in
a vessel A, and cross bars or plates c; d, arranged in radial series, for treating
one or more warps in the manner substantially as herein described and shewn.
Secondly. In a machine for dyeing or scouring warp or warps, the combination
with discs or wheels D, D', and a central shaft, of cross bars or plates for sup-
porting the warp, provided longitudinally with curved or rounded edges and
arranged in radial series together with means for oscillating same for the purpose
of gripping or holding the warp as it emerges from the liquor substantially as
described.
Thirdly. The general arrangement and construction of apparatus for dyeing and
scouring warp or warps in manner substantially as shewn and described.
