IMPROVEMENTS IN MACHINERY OR APPARATUS USED IN RING SPINNING."
These improvements relate to the ring and traveller used in ring spinning and
their object is to facilitate the spinning of various counts on a spindle without the
necessity of changing the traveller for each count. This Invention consists in
making the ring loose upon a foundation ring fastened in the rail instead of fast
in the rail as heretofore and so holding it to the foundation ring that it can follow
the traveller and give the necessary drag. I find by this arrangement I can spin
a considerable range of counts without the necessity of changing the traveller as
heretofore. I connect the loose ring to the foundation ring by a spring clip or clips
or other suitable contrivance so that such loose ring can be easily removed at any
time for cleaning or other purposes.

" IMPROVEMENTS IN MACHINERY OR APPARATUS USED IN RING SPINNING."
These improvements relate to the ring and traveller used in ring spinning and
their object is to facilitate the spinning of various counts on a spindle without the
necessity of changing the traveller for each count. This Invention consists in
making the ring loose upon a foundation ring fastened in the rail instead of fast
in the rail as heretofore and so holding it to the foundation ring that it can follow
the traveller and give the necessary drag I find by this arrangement I can spin
a considerable range of counts without the necessity of changing the traveller as
heretofore I connect the loose ring to the foundation ring by a spring clip or clips
or other suitable contrivance, so that such loose ring can be easily removed at any
time for cleaning or other purposes..
And in order that this my said Invention may be the more readily understood
and carried into practical effect I have hereunto annexed a Drawing illustrative of
my improvements and will now proceed to describe the same with the assistance
of the various figures and letters of reference marked thereon.
Figure 1 is a front view balf in section and Figure 2 a plan of my improved ring
and foundation ring-shewing how the one supports the other and the mode of
securing together, and Figures 3 and 4 are front views respectively (half in section)
of the ring and foundation ring shewn separate from each other.
a; is the foundation ring which is fixed securely in the ring rail b. This
foundation ring is constructed with an annular shoulder a¹ projecting a short
distance upwards inside the loose ring c and so effectually guides the latter which
is free to revolve upon it. The upper flange d of this loose ring c, supports the
traveller in the ordinary manner.
e. e. e are spring clips attached to the foundation ring and which yield sufficiently
to allow of the insertion and withdrawal of the lower flange of the loose ring c
and yet do not press sufficiently to interfere with the free revolution of
such ring.
It will thus be observed that in accordance with my Invention the ring c is free
to revolve upon the foundation ring and thus to follow the traveller rendering it
possible to spin a large variety of counts on a spindle without the loss of time and
expence involved in changing the traveller for each count as heretofore. It is also
found in practice that by the ring c being able to revolve and follow the traveller
considerably less strain is put upon the yarn and hence less waste of material is
produced. In addition to this I find it possible to get more yarn wound upon
a bobbin than has hitherto been practicable.
In figure 5 I represent a front view and in figure 6 a plan of the same description
of ring and foundation ring but instead of securing them together by spring clips
as in figures 1 to 4 a half groove f is formed in the shoulder of the foundation ring
and a corresponding half groove in the inside of the loose ring c, into which is
inserted a wire i the ends of which do not come close together (as illustrated
separately in figure 7) and thus such wire acts as a spring to keep the loose ring c
in position upon the foundation ring a, but does not interfere with the free
revolution of the one upon the other-whilst such spring i yields sufficiently to
allow of the ready removal and replacement of the loose ring c.
In figure 8 I illustrate a front view and in figure 9 a plan (partly in section) of a

page_text: modification which may be used instead of those previously described and illus-
trated. In this modification the lower flange of the rings jare free to revolve in
corresponding recesses k formed in the ring rail such rings being retained
in position by the screw plates m. It will be observed that these plates m extend
over and partially embrace the lower flanges n but do not interfere with the free
revolution of the rings j.
In figure 10 I illustrate a front view and in figure 11 a plan (partly in section)
of a further modification which may be used and which is similar in construction
to the arrangements described in the Specifications of Letters-Patent granted to.
Thomas Coulthard on the 12th and 23rd July A.D. 1881 and numbered respectively
3046 and 3233 but instead of having the lips o to press firmly upon the upper
side of the lower flange p of the ring q and thus to fasten the same to the
ring-rail, in accordance with this Invention, these lips are slightly raised and
arranged to simply hold the lower flange p in position and to permit the ring o̟ to
revolve as and for the purposes hereinbefore described.
Having thus particularly described and ascertained the nature of this my said
Invention together with the best methods with which I am acquainted for
carrying the same into practical effect I wish it to be distinctly understood that
I do not confine myself to the precise details, relative proportions or dimensions
of the various parts of my improved machinery or apparatus used in ring spinning
as the same may be considerably varied without departing from the Invention but
what I claim in such machinery or apparatus is :-
1st So mounting the ring which carries the traveller that the same is capable
of revolving and following the traveller in contra-distinction to being fastened
to the ring-rail, as heretofore, substantially as and for the purposes hereinbefore
described.
2nd The arrangements whereby the loose ring is mounted and secured in
position upon the ring-rail and yet capable of revolving substantially as and
for the purposes hereinbefore described and illustrated on the accompanying
Drawing.
In witness whereof I the said Edward Clarke have hereunto set my hand
and seal this 14th day of July in the year of our Lord, One thousand,
eight hundred and eighty two.
