Improvements in or connected with the Dyeing or Colouring and
Sizing of Yarn, and in Apparatus therefor.
I, JOHN TATTERSALL of Globe Works and Stores 338 Oldenzaalsch Straat Enschede
in the Kingdom of The Netherlands, Merchant 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:-
For certain shades of colours, it has been the rule up to the present time, to mix
the dyeing materials along with the size. This operation caused very much
trouble to the sizer in having to thoroughly clean out the size or sow box and in
taking off the flannels or cloths from the squeezing rollers, in order to prevent the
grey or white yarn, which would have to be sized next or in the succeeding opera-
tions from becoming stained or spotted by the coloured size, remaining on the
rollers or in the size box. My invention has for its object to remove this drawback
and also to prevent the loss of coloured size, which had hitherto mostly to be
thrown away, as it cannot be kept long enough in good condition until the same
shade of colour is again required.
The invention will be described with reference to the accompanying drawings,
in which:
Figure 1 is a side elevation of a sizing machine to which my invention has been
applied.
Figure 2 is a detail view in vertical section of the colouring rollers.
Figure 2 is a transverse section of the rollers showing the course taken by the
fabric through the rollers.
Figure 3 is a side elevation to a larger scale of part of Figure 1.
Figure 4 is a transverse section of Figure 1 showing the colouring rollers and
pump for circulating the colouring material in the trough.
To overcome all the aforesaid difficulties I place a trough or box E which can
be made of any suitable material, between the size or sow box A and the drying
part D of the sizing machine. In this trough EI place one or more rollers F G
(Fig. 2) in some cases an adjustable extra roller H (Fig. 2) for immersing the
yarn in the liquid before it passes through the squeezing rollers, but this will not
be generally required. On the top of the roller F I place a squeezing roller G,
covered with flannel or cloth or other like material. The bottom roller I drive
directly by means of its shaft R or let it be rotated by the drawing off of the yarıs
as I may prefer according to circumstances.
The bottom roller F may also be covered with cloth or other suitable pliable
substances or material.
When yarn has only to be sized and not coloured, I simply lift up the top
squeezing roller G onto a rest, so that it ceases to rotate with the roller F. The
sized yarn is then left free to pass between the bottom roller and the top roller,
without colouring the yarn as shown in dotted lines in Figure 1. The colouring
material is constantly conveyed from one side of the trough E to the other by means
of a suitable pump such as K as shown in Figures 3 and 4. It is immaterial

page_text: whether the yarn be sized and dried in one or two operations, or whether sized in
the tape or slasher, or dressing or ball warp sizing machine.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improvement in the dyeing or colouring and sizing of yarn, which
consists in dyeing the yarn after it has been sized, and before it is dried.
substantially as hereinbefore set forth whether the yarn be sized and dried in one
or in two operations, and whether it be sized in the tape, slasher, or dressing or
all warp sizing machine.
2. The improvement in or connected with machines or apparatus for dyeing or
colouring and sizing yarn, which consists in providing such machines with a
separate colouring trough between the size or sow box and the arier and in so
arranging within said trough a pair cf colouring rollers that the sized yarn passing
through said rollers is dyed, whilst when no dyeing is required the upper roller
may be lifted sufficiently to allow the yarn to pass without touching the rollers
substantially as set forth.
3. The improved dyeing or colouring device for yarn dyeing and sizing
machines substantially as described and illustrated.
