PROVISIONAL SPECIFICATION.
Improvements connected with Bobbins used in Machines for
Preparing Cotton and other Fibrous Materials.
We, JAMES ANDERTON SUTCLIFFE, of Globe Works, Blackburo, in the
County of Lancaster, Sheet Metal Engineer, and GEORGE PALEY, of Bank Top
Mills, Preston, in the same county, Cotton Spinner and Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements connected with bobbins used in machines
for preparing cotton and other fibrous materials of the class described in the
Specification of Letters Patent No. 18,561 of 1892 namely bobbins having their
tubular body part composed of corrugated sheet metal the corrugations running
either lengthwise of the said tubular body part or round it and a plain or
uncorrugated part being left at each end of the tube into which were fitted and
secured metal or wood plugs or end pieces forming the top and bottom of the
bobbin. Now according to this invention we form the corrugations spirally of the
tube and continue the spirals to the very top of the tube which receives and tightly
embraces a wooden or other suitable plug or end piece. By this arrangement not
only is greater strength and resistance to injury imparted to a sheet metal bobbin
but the spiral- or quick screw-threaded-form of the corrugations greatly facilitates
the operation of "sloughing-off"-that is to say removing the sliver remaining on
the nearly empty bobbin when removed from the creel to be replaced by a
full one.

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 improvements connected with bobbins used in machines

continue the spirals to the very top of the tube which receives and tightly embraces
a wooden or other suitable plug or end piece. By this arrangement not only is
greater strength and resistance to injury imparted to a sheet metal bobbin but the
spiral or quick screw-threaded-form of the corrugations greatly facilitates the
operation of "sloughing-off"-that is to say removing the sliver remaining on
the nearly empty bobbin when removed from the creel to be replaced by a full one.
In the accompanying drawings Fig. 1 illustrates a "long collar" bobbin having
its tubular body part a spirally corrugated. are the top and bottom wooden
end pieces which may be constructed and secured in position according to our
former Patents Nos. 22,020 A.D. 1893 and 6412 A.D. 1894 or in any other
convenient manner. We prefer however to form an internal collar against which
the lower edge of the wooden end piece rests by means of intermittent inward
projections d d (see diagrammatic plan view at Fig. 2 the outer line e corresponding
with the external diameter of the corrugated bobbin). By this arrangement of
indentations the operation of sloughing-off or untwisting the remaining cotton
from off the bobbin is facilitated. But when preferred we may (see Fig. 3) readily
form near the upper end of the bobbin a bead or collar to prevent the cotton
sloughing-off.
Fig. 4 shews our invention applied to an ordinary form of "short collar
bobbin.
"
The spiral corrugations are formed in the first instance in a flat plate of sheet
metal between a pair of suitably grooved compressing rollers the corrugated sheet
metal being afterwards bent round to a tubular form the adjoining edges being then
secured together by an internal "groove sean" (i.e. the ordinary form of folded or
overlapped joint) or other convenient form of joint.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
Making the tubular body part of bobbins used in machines for preparing cotton
and other fibrous materials of spirally corrugated sheet metal substantially as
herein described and shewn in the drawings.
