PROVISIONAL SPECIFICATION.
Improvements in Spinning Certain Cotton Yarns.
We, JAMES HENRY LEES-MILNE, of Crompton Hall, Shaw near Oldham, in
the County of Lancaster, Cotton Spinner, and MAX BAERLEIN, of 12 Blackfriars
Street, Salford, Manchester in the said county, Merchant, do hereby declare the
nature of this invention to be as follows:-
.
This invention relates to what is generally called "mixed or mottled yarn."
The methods hitherto employed are to dye and mix the loose cotton previously
to passing it through the opener scutcher or card, or to dye carded cotton in the
sliver and mix different slivers on a finishing card or on drawing or alubbing
frames. All these methods require a mill or machinery to be more or less specially set
apart or arranged for coloured work. They require special treatment and con-
siderable care in different processes of spinning and are only applicable for
treating to advantage large quantities of one colour or shade as otherwise the
manipulations would be very expensive and cause many remnants difficult to use
again and also much waste.
Our improved system consists in running on the drawing frame along with the
sliver of cotton one or more ends of dyed roving produced on slubbing inter-
mediate or roving frames. We dye this roving either in bobbins or in the hank
and make suitable provision on the drawing frame so as to allow the roving to run
off along with the slivers. If dyed on the bobbin we slip a perforated tube over
the usual wood bobbin or we substitute this latter by a perforated metal bobbin
and spin the roving on the perforated tubes or bobbins, dyeing them subsequently
by any of the systems employed for dyeing cops or bobbins.
If dyed in the bank.we reel the roving and subsequently dye and treat it exactly
as though it were finished yarn.
This blending of dyed roving and cotton slivers ensures a thoroughly even
distribution of the coloured thread or threads of roving with the slivers in proportion
to their relative counts.
The subsequent processes are exactly the same as for the ordinary spinning of
grey yarn..
By preference we mix the slivers and the roving on the first head of the drawing
frame so that they pass through the rollers together and we then pass the blended
elivers through another head or more than one head as customary in ordinary
spinning. The doubling processes obtained in the drawing frame and in subsequent
machines produce a thoroughly even mixture whilst the twist of the roving,
which is slight to commence with, practically disappears through the repeated
drawing out.
The dyeing of bobbins or hanks can be effected outside the mill by any ordinary
cap or bobbin or bundle dyer so that any spinner of grey yarn can at once adopt
this system only very trifling preparations being required for it.

We, JAMES HENRY LEES-MILNE, of Crompton Hall, Shaw near Oldham, in
the County of Lancaster, Cotton Spinner, and MAX BAERLEIN, of 12 Blackfriars
Street, Salford, Manchester, in the said county, 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 :-
This invention relates to what is generally called "mixed or mottled yarn."
The methods hitherto employed are to dye and mix the loose cotton previously
to passing it through the opener, scutcher or card, or to dye carded cotton in the
sliver and mix different slivers on a finishing card or on drawing or slubbing
frames. All these methods require a mill or machinery to be more or less
specially set apart or arranged for coloured work. They require special treatment
and considerable care in the different processes of dyeing and spinning and are
only applicable for treating to advantage large quantities of one colour or shade
as otherwise the manipulations would be very expensive and cause many remnants
difficult to use again and also much waste.
Our improved system consists in running on the drawing frame along with the
sliver of cotton one or more ends of dyed roving produced on slubbing intermediate
or roving frames. We dye this roving either in bobbins or in the hank and make
suitable provision on the drawing frame so as to allow the roving to run off along
with the slivers. If dyed on the bobbin we slip a perforated tube over the usual
wood bobbin or we substitute this latter by a perforated metal bobbin and spin the
roving on the perforated tubes or bobbins, dyeing them subsequently by any of the
systems employed for dyeing cops or bobbins.
If dyed in the hank we reel the roving and subsequently dye and treat it
exactly as though it were finished yarn.
This blending of dyed roving and cotton slivers ensures a thoroughly even
distribution of the coloured thread or threads of roving with the slivers in
proportion to their relative counts.
The subsequent processes are exactly the same as for the ordinary spinning of
grey yarn.
By preference we mix the slivers and the roving on the first head of the drawing
frame so that they pass through the rollers together and we then pass the blended
slivers through another head or more than one head as customary in ordinary
spinning. The doubling processes obtained in the drawing frame and in subse-
quent machines produce a thoroughly even mixture whilst the twist in the roving,
which is slight to cominence with, practically disappears through the repeated
drawing out.
The dyeing of bobbins or banks can be effected outside the mill by any ordinary
cop or bobbin or bundle dyer so that any spinner of grey yarn can at once adopt
this system, only very trifling preparations being required for it.
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. Passing through the drawing frame along with cotton slivers any number of
threads of dyed roving produced on slubbing, intermediate or roving frames and
subsequently finishing by the ordinary processes of cotton spinning so as to produce
a mixed or mottled yarn.

along with the cotton slivers any number of threads of dyed roving and subse-
quently finishing by the ordinary processes of cotton spinning.
