PROVISIONAL SPECIFICATION.
Improvements in the Production of Yarn and in Machinery
therefor.
I JAMES SCHOFIELD of Crofthead, Littleborough in the County of Lancaster,
Cotton Manufacturer, do hereby declare the nature of this Invention to be as
follows:
My Invention relates principally to the production of cotton yarn having a more
wool like appearance than ordinary cotton yarns Cotton yarn has been produced
from mixtures of dyed and undyed cotton and previously to my present invention I
have been dividing the fleece of such carded mixture into narrow strips or slivers and
winding these strips on to bobbins which have been transferred to the spinning
frames.
According to my present invention I provide a condenser carding engine with ring
spinning spindles so that the strips of divided fleece are led directly to the spindles
and are twisted in a suitable degree and wound in the condition of yarn upon the
bobbins tubes or spindles as the case may be. Between the condenser rubbers and the
speed suitable to pass
spindles interpose nipping rollers which are driven at a
forward the ends from the condenser the said rollers also checking the passing back-
ward of the twist. By thus combining together the carding and spinning operations
1 dispense with the operation of winding the divided fleece upon bobbins and with the
intricate apparatus for effecting such winding and I obtain a yarn similar in appear-
ance to yarn produced from wool or mixtures of wool and cotton.
I do not confine myself to the use of the hereinbefore mentioned mixtures of cotton
nor to the application of my Invention to the production of cotton yarns as it may
he found to be applicable with advantage in the production of yarns from other
textile materials.

COMPLETE SPECIFICATION.
Improvements in the Production of Yarn and in Machinery
therefor.
I JAMES SCHOFIELD of Crofthead, Littleborough in the County of Lancaster
Cotton Manufacturer, 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 drawings:
My Invention relates principally to the production of cotton yarn having a more
wool like appearance than ordinary cotton yarns. Cotton yarn has been heretofore
produced from mixtures of dyed and undyed cotton and previously to my present
invention I have been dividing the fleece of such carded mixture into narrow slips or
slivers and winding these strips on to bobbins which have been transferred to the
spinning frames.
According to my present invention I provide a condenser carding engine with ring
spinning spindles so that the strips of divided fleece are led directly to the spindles
and are twisted to a suitable extent and wound in the condition of yarn upon the
bobbins, tubes or spindles as the case may be. Between the condenser rubbers and
the spindles I interpose nipping rollers which are driven at a speed suitable to pass
forward the ends from the condenser, the said rollers also checking the passing back-
ward of the twist. By thus combining together the carding and spinning operations
I dispense with the operation of winding the divided fleece upon bobbins and with the
intricate apparatus for effecting such winding and I obtain a yarn similar in appear-
ance to yarn produced from wool or mixtures of wool and cotton.

To render the aforesaid arrangement of mechanism more easily understood I will
now describe the same more particularly with reference to the annexed drawing.
The said drawing shows the delivery end of a carding engine fitted with spindles
and nipping rollers for the purpose of carrying my invention into effect. Only the
parts which are requisite for the purpose of explanation are shown in the drawing.
The broken portion of a cylinder marked a is a portion of the carding engine main
cylinder. The doffing cylinder is marked b and the doffing comb c. The fleece is
indicated by the dotted line marked a. When the fleece is removed from the
doffing cylinder by the comb c it is led between a series of discs d which are
-threaded upon a common centre e. These discs or it might be any other dividing
means split the fleece up into a corresponding number of strips of sliver each strip
being thereafter twisted into a yarn. The sliver strips now enter between the endless
travelling aprons ff carried on rollers g y and constituting the condenser rubber.
This condenser rubber is at present in common use and therefore in itself forms no
part of my invention. One of the rubber aprons, or it might be each apron, receives
a reciprocatory motion at right angles to the direction of traverse. The consequence
is that in their progress through the rubber the strips of sliver æ are rubbed and rolled
between the aprons an operation which assists to equalise, consolidate and distribute
inequalities preparatory to the fibres being twisted together. I may apply more than
one of these rubbing aprons arranged so that the strips of sliver pass from one to the
other in which case I may drive one rubber faster than the preceding one. Upon
leaving the rubber ff the sliver strips a pass forward to the nipping rollers 7.
These nipping rollers are driven at a speed suitable to pass forward the strips and
also prevent the twist given by the spindles i from passing backward to the rubber.
After passing between the nipping rollers, the ends are led through guides; to the
travellers whereby the twisting and winding is effected upon the revolving spindles i
as is well understood. The building rail is marked and the bottom rail m.
spindles are driven by hands n and a drum which receives motion from the axis of
the main cylinder a or from any other suitable moving part of the carding engine.
The fibres in each sliver strip & are twisted together like so many ends, and form
yarns which possess the appearance of wool yarns and are applicable in the manu-
facture of many fabrics and articles in making which the employment of wool yarns
has hitherto been considered an essential.
The
I do not confine myself to the use of the herein before mentioned mixtures of cotton
nor to the application of my Invention to the production of cotton yarns as it inay, be
found to be applicable with advantage in the production of yarns from other textile
.materials.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The use in the manufacture of cotton yarns of the apparatus substantially a
described and illustrated whereby yarn having a wool like appearance is produced.
2. The manufacture of yarns from cotton or other fibres by dividing the fleece as it
leaves the carding cylinder into a series of strips and twisting the fibres of each of
the said strips upon themselves by means of spindles forming a part of or directly
connected with the carding machine the carding and twisting forming a continuous
operation substantially as described and shown.
3. An apparatus for manufacturing yarns of the indicated nature consisting of the
combination of the carding engine, fleece divider, condenser rubber and nipping
rollers with spindles for twisting and winding the yarns substantially as described and
as illustrated.
