Improvements in the Method of and Apparatus for Colour Classing
and Designing for the Manufacture of Textile Goods.
We, WALKER LITTLEWOOD of 16 Bingley Street, Leeds, Warp Dresser and
ISAAC INGHAM of 22 Castle Street, Leeds, Engineer, both in the County of York,
do hereby declare the nature of this invention, to be as follows:-
We employ a series of endless warps containing short lengths of all the shades
required, the warps are carried by dividing rollers at each end of the frame, and
pass through healds and reeds towards each end of the frame, by moving the
healds the bottom colours and the top colours on the warp are mixed or brought
together, and by moving the rollers one way or the other the whole of the colours
or sections of colours are again changed.
Also by moving by hand the position of alternate warps upon their rollers or by
altering the position of any series of warps, different colours and designs are again
obtained, so that at each change, if there are forty-eight colours or sections, forty-
eight different effects are simultaneously obtained.
To regulate the fineness of the sets the reeds can be turned to an angle to
produce the fineness required, by drawing the threads or yarn of the warp closer to
each other.
The colours may be numbered and similar numbers be placed on the frame of the
machine opposite where each section of colour should be when classed.
The warps may be also of two or more twisted colours or of any different material
required, such as cotton, silk, mohair and the like.

Improvements in the Method of and Apparatus for Colour Classing
and Designing for the Manufacture of Textile Goods.
We, WALKER LITTLEWOOD, of 16 Bingley Street, Leeds, Warp Dresser, and
ISAAC INGHAM, of 22 Castle Street, Leeds, Engineer, both in the County of York,
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 consists of improvements in the method of and apparatus for
colour classing and designing for the manufacture of textile fabrics.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a side elevation of apparatus according to our invention.
Fig. 2, is a plan of the lower part of such apparatus, through the line A, B.
Fig. 3, is a plan of the top part of such apparatus.
Fig. 4, is a view showing the manipulation or moving of the threads to produce
variation in pattern or design.

page_text: Fig. 6, is a detail view of fluted dividing rollers with locking device.
Fig. 7, is a end elevation of same.
Fig. 8, is a side view showing modification of our invention.
In carrying out our invention we employ an endless warp made up of threads or
cords C containing lengths of the shades required, so forming the said warp into
sections of any required number.
Each section of the said warp represents one particular or "solid" colour. The
said threads or cords C are carried by or pass over dividing rollers D, E, F, and G,
and through reeds or raddles J, K, L, and M made of bars carrying a series of
pins between which the said threads or cords C are passed.
The frame comprises a lower H and top portion H', the top portion being
supported by pillars N, and carries two sets of rollers Ni and N³, and O and O.
The said rollers N', N2, O and O' are journaled in pedestals R upon the frame H¹,
and the lower rollers N2 and O' are adjustable relatively to the top ones by means
of sliding bearinge S, springs T, screws T', hand wheels U, and frames V, by which
the said rollers are caused to move the threads or cords C when the top rollers are
rotated by means of the hand wheel W. The first set of rollers N¹ and N' are for
moving along or winding round the whole of the threads or cords at once, and the
latter set O and O' for changing certain of the threads or cords so as to vary the
classifying of the colours by moving the threads or cords in an end to end manner,
as hereinafter explained.
Upon the frame H' is a clamp composed of a fixed bar X and adjustable bar X¹,
the adjustment of which is effected by means of bolts X' and thumb screw X³.
The said threads or cords are divided by bars P into two series, both of which
pass between the rollers N' and N³, but only one series passes between the rollers O
and O', the other series passing under the lower roller O'. To regulate the
fineness of the "sets" pivotted reeds or raddles Y are fixed on the frame H and
are so centred that they can be turned to an angle to produce the fineness required
by drawing the threads or cords closer to each other. The said reeds or raddles
are carried in clamps Z' bolted to an adjustable screw Z³.
The colours may be numbered and similar numbers placed on the frame of the
machine opposite where each section of colour should be when classed.
The warp threads may also be of two or more twisted colours, or of any different
material required, such as cotton, silk, mohair, and the like.
The dividing rollers D, E, F, and G are carried in bearings Z³ and can be
locked at one side of the machine by means of pins Z passing through the
flanges Z³.
The said dividing rollers may be either plain or fluted. The object of the
flutings is to prevent lateral or sideways motion of the threads during their motion
while under manipulation; when plain rollers are used a raddle Z' is fixed on the
movable bar Z which is adjustable in the slot Z so that it can be moved relatively
to the dividing roller D which is carried on a sliding piece Z, which is made so as
to be slid, for taking up any slackness in the endless warp threads, by means of
slot Z10 and bolt and thumb-screw Z"
Fig. 8. In this modification the threads are divided by two sets of dividing
rollers, so that they do not catch one another during the travelling of the threads.
Fig. 4 shows how the threads or cords are manipulated.
The action is as follows:-
―:
The winding rollers N¹ and N³, and O and O' are open or out of contact with
the threads or cords C and the dividing rollers D, E, F, and G are unlocked so
that the threads or cords C are free to be moved at will. The operator slides such
threads or cords into one section as he requires to produce the design in that
section, (the sections or lengths of the threads or cords are interchangeable) and
by this action all the other sections are changed, the threads or cords producing
simultaneous designs throughout the machine, which may be either mixed or what
is known as a "solid" colour.

page_text: The said designs can be examined by screwing up the lower roller N2 so that
the rollers N' and N2 pinch or bite on the said warp, the hand wheel W is then
turned and the said warp travels or is wound round the machine by which means
all the designs produced are brought alternately under examination.
In order to vary the designs from solid colours or to bring the threads or cords
into what is known as "end and end" or to blend them, the lower roller N* is put
out of contact with the said warp and the lower roller O¹ is screwed up.
The clamp upon the frame H is then applied by moving up the bar X', so that
every other thread or cord is held from travelling, the said rollers O and O¹ move
the remaining or alternate threads and bring them round so as to blend them or
bring them into end and end, so producing a varied design, and by moving the said
endless warp threads one more section another complete class or series of designs
is produced throughout the machine. In these cases the dividing rollers D, E, F,
and G are locked.
By moving the sections only half way double the number of designs may be
produced.
Y' Y Y Y and Y are guide bars or ribs for the threads.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A method of colour classing and designing, for producing patterns for the
manufacture of textile goods, by manipulating endless warps composed of threads
or cords of various colours or sections of colours, so that a series of designs or
colour effects are simultaneously produced, substantially as set forth.
2. A machine or apparatus for colour classing and designing, for producing
patterns for the manufacture of textile goods, by manipulating endless warps com-
posed of threads or cords of various colours, so that a series of designs or colour
effects are simultaneously produced, substantially as set forth.
3. The combination of an endless warp composed of a series of threads or
cords C, dividing rollers D, E, F, and G, frames H and H', rollers N' and N³, O
and O¹, arranged and operating, substantially as and for the purposes shown and
described.
