I, WILLIAM SUGDEN CLAPHAM, of Keighley, in the county of York, Spinner,
do hereby declare the nature of the said invention for "IMPROVEMENTS IN EFFECTING
THE DRAG AND SMOOTHING THE FIBRES OF YARN IN ROVING, SPINNING AND
TWISTING to be as follows:-
"
"
My invention relates to improvements in producing the necessary drag" or
tension upon yarns, during the operation of roving, spinning and twisting and at
the same time, and by means of the same apparatus, smoothing or turning in the
loose fibres of the yarn thereby giving it a better finish.
To carry out my improvements I support either within the mouth or lower part
of the inside of the cap or at the lower part of and surrounding (or encircling) the.
outside of such cap, a smooth ring of metal which is perfectly plain, and has no
projections upon its upper surface.
This ring is formed of wire or other suitable material having a circular transverse
section, and is supported by a light bracket or brackets attached by screws or
bolts to a rail placed across the spinning frame for that purpose. The yarn passes
down the outside of the spinning cap and under the bottom edge of such cap and
thence over the upper surface of the above named smooth ring to the revolving
spool or bobbin or where the ring is supported outside the cap the yarn passes
between the ring and the cap. During the period that the yarn is passing under
the bottom edge of the cap and over the upper portion of the smooth ring the
loose hairs or fibres are turned in by contact with these two smooth surfaces and
a smoother and better finished yarn is produced..

of Yarn in Roving, Spinning, and Twisting.
I WILLIAM SUGDEN CLAPHAM, of Keighley, in the county of York, Spinner,
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:-
"
My invention relates to improvements in producing the necessary "drag ΟΙ
tension upon yarns during the operation of roving, spinning and twisting and at
the same time and by means of the same apparatus smoothing or turning in the
loose fibres of the yarn, thereby giving it a better finish.
To carry out my invention I support either within the mouth or lower part of
the inside of the cap, or at the lower part of and surrounding the outside of such
cap, a smooth ring of metal which is perfectly plain and has no projections upon
its upper surface. This ring is formed of wire or other suitable material having
a circular or semi-circular transverse section and is supported by a light bracket or
brackets, attached by screws or bolts to a rail placed across the spinning frame
for that purpose.
The yarn passes down the outside of the spinning cap and
under the bottom edge of such cap, and thence over the upper surface of the above
named smooth ring to the revolving spool or bobbin or where the ring is supported
outside the cap, the yarn passes between the ring and the cap.
During the period that the yarn is passing under the bottom edge of the cap
and over the upper portion of the smooth ring, the loose hairs or fibres are turned
in by contact with these two smooth surfaces and a smoother and better finished
yarn is produced.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing, in which figure 1, represents
an elevation of an ordinary cap and spindle, for cap spinning, with my improved
apparatus applied thereto. Figure 2 represents a sectional elevation of the same.
Figure 3 represents a plan of my improved yarn smoothing ring and figure 4
a sectional elevation of the same. Similar letters refer to similar parts in all the
figures of the drawing.
An ordinary spinning cap is represented at A, with the spindle B, the wharle C,
and the tube E, upon which is placed the bobbin D, upon which bobbin the yarn
is wound as it is spun. My improved ring for giving the required tension and
twist to the yarn, and at the same time for turning in the loose and starcy fibres
thereof, is represented at F, and is supported by a tongue G, in which is formed a
slot H, through which a bolt I, is passed for the purpose of holding the tongue,
which supports the ring F, to the rail J, which is fixed across the spinning frame
for that purpose. The upper surface of the ring F, over which the yarn passes on
its way to the bobbin, is perfectly smooth, and nearly semi-circular in transverse
section and has no projection or flange of any kind. This ring is fixed in close
proximity to the bottom of the cap and projects slightly into the interior thereof,
so as to ensure the yarn having to pass over the smooth upper surface of the ring,
at whatever level the bobbin may be working inside the ring.

page_text: The yarn in passing through the narrow regulated space between the two smooth
surfaces presented by the bottom of the cap A, and the upper surface of the ring F,
is slightly nipped between these two surfaces and the required amount of tension
and twist is thereby obtained, in addition to which, as the yarn is passing through
the narrow space herein before mentioned, and is at the same time twisting, the
loose starey fibres are turned in by the smooth surfaces with which they come in
contact and thereby a smoother and better finished yarn is produced.
Where it is found preferable to fix the smoothing ring outside the cap, the
tension is obtained, and the loose fibres are turned in as the yarn passes between
the outer surface of the cap and the ring.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is
The use of a ring, of the form and construction herein described, in combination
with an ordinary spinning cap for smoothing and giving the required tension to
yarns, in the processes of roving, spinning and twisting in the manner substantially
as herein set forth.
