An Improved Method of Preparing Cotton and other Fibrous
Materials for Spinning.
We, BENJAMIN ALFRED DOBSON, Engineer, of Kay Street Machine Works,
Bolton, in the County of Lancaster, and JAMES THORNTON, Mill Manager, of
117 Rishton Lane, Great Lever, Bolton aforesaid, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to an improved method of preparing in slubbing,
intermediate, roving and jack frames, cotton and other fibrous materials for
spinning.
It is now customary to take full bobbins of slubbing from the first preparing
machine on which the yarn is wound upon bobbins and place these bobbins in a
creel upon the next preparing machine on which the ends of two bobbins are
passed together through the drawing rollers and wound together or doubled upon
a single bobbin.
According to our invention instead of passing the two ends together through
the drawing rollers of the preparing machine we pass the two ends separately
through the drawing rollers and then wind together or double such ends upon a
single bobbin.
By this method a better and more perfect drawing of the material in the rollers.
is ensured.
Other advantages are that the fly frames only require one line of spindles and
the lift and size of bobbins can be considerably increased to spin the same
numbers. Thus for example, in taking a bobbin from a roving frame to a mule or
spinning frame instead of having say two bobbins of twelve hank roving seven
inch lift to be doubled behind the rollers it would be quite possible to work with a
six hank roving and nine inch lift.

An Improved Method of Preparing Cotton and other Fibrous
Materials for Spinning.
We, BENJAMIN ALFRED DOBSON, Engineer, of Kay Street Machine Works,
Bolton, in the County of Lancaster, and JAMES THORNTON, Mill Manager, of
117 Rishton Lane, Great Lever, Bolton aforesaid, 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 relates to an improved method of preparing in slubbing,

page_text: intermediate, roving and jack frames, cotton and other fibrous materials for
spinning.
It is now customary to take full bobbins of slubbing, from the first preparing
machine on which the yarn is wound upon bobbins and place these bobbins in a
creel upon the next preparing machine on which the ends of two bobbins are
passed together through the drawing rollers and wound together or doubled upon
a single bobbin.
This method is illustrated by the arrangement shown in Figure 1 of the
accompanying sheet of drawings in which a designates the bobbins, 6 the ends of
slubbing, c the drawing rollers and d the flyer bobbins upon which each pair of
ends bare wound.
According to our invention as illustrated by the arrangement shown in Figure 2
instead of passing the two ends 6 together through the drawing rollers c of the
preparing machine we pass the two ends b separately through the drawing rollers c
and then wind together or double such ends upon a single bobbin d.
By this method a better and more perfect drawing of the material in the rollers
is ensured.
Other advantages are that the fly frames only require one line of spindles and
the lift and size of bobbins can be considerably increased to spin the same
numbers. Thus for example, in taking a bobbin from a roving frame to a mule
or spinning frame instead of having say two bobbins of twelve hank roving seven
inch lift to be doubled behind the rollers it would be quite possible to work with
a six hank roving and nine inch lift. Again, the machine can be run at twice the
speed as under the old method illustrated by Fig. 1 and consequently the
same production can be obtained with half the number of spindles and flyer
bobbins.
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 :-
The improved method of preparing cotton and other fibrous materials for
spinning, said method consisting in passing the ends from the bobbins on the creel
of a preparing machine separately through the drawing rollers and then winding
two such ends together or doubling them upon a single flyer bobbin substantially
in the manner and for the purposes herein set forth.
