FRANCIS RABBETH, of the City of Providence, County of Providence, State of
Rhode Island, United States of America. ." IMPROVEMENTS IN AND RELATING TO
SPINNING AND TWISTING RINGS." Partly a communication from John Booth, of
Lincoln, State of Rhode Island, aforesaid.
This Invention has reference to improvements in spinning rings, such as are used
on that class of spinning machinery known in the art as ring spinning machines,
and consists in the peculiar form of the ring and the means by which the same is
secured to the ring rail, so that, when desired, the ring can be readily reversed.
In the Drawing,
Figure 1 represents three modifications of my improved spinning or twisting ring
secured to a portion of a ring rail, forming part of a ring spinning or twisting
machine in perspective and partly in section.
Figure 2 represents another modification in section, and Figures 3, 4, 5, and 6,
represent different modifications of the ring and the means for securing the same to
the rail in section.
Similar letters of reference indicate corresponding parts in all the Figures.
a represents the ring rail; b, a plain cylindrical or tubular ring practically of
uniform thickness, except at or near the centre of its width where it is provided
with a projecting rim or a groove for the purpose of securing it to the ring rail;
c represents the traveller which in the narrow modification is of the usual form,
but instead of being in a horizontal or inclined position is in a vertical position,
the closed portion being in the ring and the open portion extending over the edges
on the outside of the ring, the thread can therefore be easily passed under the
traveller in piecing.

page_text: In the wider modification of the ring the traveller is modified,, and whilst the
upper portion preserves the curved loop the lower portion is made nearly straight,
so that the traveller will not extend too much from the inside of the ring and
interfere with the bobbin, as is shewn in the right hand ring in Figure 1.
Figure 5 represents a ring, provided with a shoulder d', projecting from the
outside of the tubular ring at the middle of its width and arranged to fit into a
recess in the ring rail, so that the ring can be easily reversed, and when one end is
worn the other presented to the wear; the ring is secured in the ring rail by the
screw e in the usual manner; d, d, d, are split ring holders made to secure the ring
to the ring rail; the portion of the holder fitting in the ring rail may be concentric
with the ring, or if an adjustable ring is desired excentric with the same so that
by turning the holder the centre of the ring may be adjusted to the spindle.
Figure 3 represents the ring, provided on the outside with a groove in the centre
of its width, into which the holder enters. The holders are all constructed so as
to leave the lower edge of the tubular ring free, and allow the traveller to freely
slide on the same as also the bent end to pass behind the ring.
Figure represents a narrow tubular ring, provided with a narrow groove,
preferably V shaped, into which the edge of the curved split ring holder d.enters,
and by which the same is secured to the ring rail so that the ring 6 can be readily
reversed; on this narrow tubular ring b, Figure 4, the usual traveller can be used
as shown in the central ring in Figure 1, the traveller being placed vertical instead
of horizontal, the centrifugal force tends to drive the traveller outward, and it thus
bears against the two rounded edges of the ring and slides on the same without
the chattering incidental to a horizontal race and horizontal traveller.
Figure 6 represents another modification of the tubular ring b, provided with a
groove at the centre of its width, the same as the ring in Figure 3, in which a split
ring & about half the width of the groove forms a shoulder similar to the shoulder
shown in Figure 5, so that the ring may rest firmly on the surface of the ring rail,
as shown in Figure 5, in a recess, and when reversed the ring will occupy the same
position on the same plane and be secured by the screw e.
This improved tubular ring secures many advantages over rings as heretofore
made,―
First. The traveller being on the inside of the spinning ring slides freely and
evenly on the same and does not chatter, thus producing more even uniform yarn.
Second. The tension on the yarn counteracts the centrifugal force, and therefore
the traveller moves with less friction.
Third. The ring proper being small and containing little metal can be made of
the best quality of material at less cost than other rings made of inferior material.
Fourth. The ring being reversible will wear twice as long as other rings.
By means of the holders, four modifications of which are shown, and others can
be readily devised to suit peculiar conditions, the ring is firmly secured in the ring
rail on a true plane and can be easily reversed; the holders being permanent
structures, on which there is no wear, can be used with successive rings so that the
expense of renewal is confined to the small tubular ring. This ring can be cheaply
made of sheet steel by various means, and being of tubular form and uniform
section short lengths of drawn steel tubes can be cut to form these rings, and
readily finished they can thus be cheaply produced without waste of material.
This spinning ring made after either of the modifications shown can be used on
machines for twisting yarn as well as on machines for spinning, and in either when
the seat of the ring and the seat in the ring rails are made excentric can be
accurately adjusted to the spindle.
Having thus described my Invention, I claim as new and desire to secure by
Letters Patent,-
First. A tubular spinning ring of uniform thickness whose edges are rounded,
and which is provided with a groove or similar device for securing the same on the
ring rail as a new article of manufacture.

page_text: Second. A tubular ring, arranged to be reversible and secured to the ring rail
by means substantially as and for the purpose set forth.
Third. The combination with the tubular ring b of the traveller c, arranged so
that the two ends of the tubular ring form the races on which the traveller slides,
the latter revolving on the inside of the ring, substantially as and for the purpose
specified.
•
Fourth. A tubular spinning ring, whose edges are rounded, and which is provided
with a groove or similar device midway its width for securing the ring to the ring
rail, so that either end of the ring can be turned upward and the ring reversed,
occupying the same position vertically, as and for the purpose set forth.
In witness whereof, I, the said Francis Rabbeth, have hereunto set my
hand and seal, this Twentieth day of June, in the year of our Lord One
thousand eight hundred and seventy-seven.
