Lancaster, do hereby declare the nature of this invention to be as follows:-
Our invention relates to certain improvements in the cup or spindle on rabbeth
and other spindles used in connection with ring spinning frames, and consists of a
metallic spring cup or spring to hold the bobbin firmly in the cup and upon the
spindle during spinning, and also a grooved metallic bobbin hoop to be used in
connection with the above.

COMPLETE SPECIFICATION.
An Improvement in connection with the Cup or Spindle used in
connection with Ring Spinning Frames and Bobbins adapted for
the same.
We, SHADLOCK WILKINSON, Overlooker of 38, Hirst Street, Burnley, JAMES
CLARKSON, Grocer, of 67 Waterloo Road, Burnley, and FREDERICK HEAP, Book-
keeper, of 64 Todmorden Road, Burnley, in the County of Lancaster, 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 the cups or spindles of rabbeth and other ring frames
and our improvement consists in metallic spring cups or springs to hold the bobbin
firmly in the cup or on the spindle during spinning or doubling and bobbins adapted
for use in connection with the same, the object of our invention being to secure the
bobbin on the spindle and prevent its lifting or rising under high speed.
On the two sheets of drawings appended hereunto, Fig. 1 shows an elevation of
the lower part of a spindle with one form of cup and bobbin in section and fig. 2
an outside view of the cup; Figs. 3 and 4 show similar views of a modification of
the cup and bobbin.
Fig. 5.shows an elevation partly in section of a third modification and fig. 6 a
plan of the same.
Fig. 7 shows a further modification of spring consisting of a tubular spring fixed
upon the outside of the sleeve. Fig. 8 shows the same spring partly in section
secured upon loss by which it is attached to the spindle.
Figs. 9 and 10 show arrangements of a similar tubular spring reversed in position
from that shown on figs. 7 and 8.
Fig: 11 shows another modification of spring consisting of a barrelled split ring.
forced into a recess made on the sleeve of the spindle and fig. 12 a plan of
the ring.
On, the different figures a is the spindle, the wharve, and c the sleeve on the
same over which the Lobbins & fits.
The cup e fig. 1 made of brass, iron, or steel is pressed upon the sleeve cas
usual. The cupped part is, made ilin and slotted with vertical slits leaving the
intermediate parts e connected to the loss of the. cup at the bottom only. so that
they can be readily sprung outwards. Near to the top edge the sides of the cup

page_text: are pressed inwards so as to form projections e on the inside. The bobbin may
he hooped at the bottom with a hoop which is even formed with a circular
groove corresponding to the projections or the bobbin itself is similarly
grooved. When the bobbin is pressed downwards on the sleeve, the lower part of
the bobbin pushes the projections and sides of the cup outwards till said ♬
The
projections drop into the groove f¹ and into the position shewn by fig. 1.
bobbin is then held firmly in its position and prevented from lifting during the
spinning and securely driven by the cup.
In the modified arrangement shewn by fig. 3 and 4, the sides of the cup g are
turned inwards at the top and the bobbin made with a bead of an outer shape
corresponding to the internal shape of the cup, so that when the bobbin is pushed
down into the cup, the elastic sides of the cup fit over the top edge of the bead h on
the bobbin as shewn by fig. 3 and hold it securely in its position.
The sides of the cup i are left

solid and a circular groove is turned in the inside of the cup. A spring blade k
bent into an eleptical or similar shape as shewn by fig. 6 in plan is let into the
groove The bottom of the bobbin is indented with a circular groove ¹,
and may be strengthened by means of a hoop of corresponding shape.
hobbin on being pushed down presses the flattened parts of the spring outwards
till the groove comes opposite to the spring k when the latter will spring into the
groove and hold the bobbin securely.
The
Instead of using a spring cup, we in some cases use a tubular spring fitted upon
the sleeve of the spindle or if more convenient, as in the case of short sleeves or
where no sleeve exists, the spring is fitted upon the spindle itself or upon a
small bush or boss made to. fit the spindle. With this arrangement the force of the
spring is made to press against the internal bore of the bobbin assisting the driving
and preventing the rise of the bobbin.
In the arrangement shewn hy fig. 7, the tubular spring m has for the greater
part of its length slits m¹ and is bulged out at the lower end m². This tubular
spring is made to fit tight both upon the spindle and the top of the sleeve. Fig. 8
shows the same kind of tubular spring m fitted upon a metal boss m³ which is driven
tight upon the spindle.
Fig. 9 shows the same kind of spring m but with the open ends of the slits
turned upwards. In this case the spring is bulged out more at its middle part and
bent over at the top end towards the spindle and forced upon the sleeve e reduced
in thickness where the spring fits in. Fig. 9 shows the same kind of spring placed
drectly upon the spindle. The spring may also be secured upon a separate boss
driven on to the spindle.
The pressure of either form of tubular spring against the bore of the bobbin holds
the latter and drives it and prevents its lifting.
Figs. 11 and 12 show a modified arrangement of internal spring. A groove or
recess n is turned in the sleeve and a barrelled split hoop o sprung into the groove.
The internal diameter of the hoop is made larger than the diameter of the recessed
part of the sleeve, and the ends of the split hoop have clearance between them as
shewn at o' on figs. 11 and 12. The bobbin when pushed down compresses the hoop
and by the outward pressure of the hoop is held firin and prevented from rising.
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.
In combination with spindles for ring frames,
Firstly. Elastic spring cups or springs fixed upon said spindles for holding the
hobbins and preventing them from rising, substantially as herein before described and
illustrated.
Secondly. The arrangement or construction of elastic spring cup and bobbin with
grooved bottom substantially as hereinbefore described with reference to figures
Fas

page_text: Thirdly. The arrangement or construction of clastic spring cup and bobbin
adapted for the same substantially as hereinbefore described with reference to
figures 3 and 4 of the drawings.
Fourthly. The arrangement or construction of grooved cup and spring and
grooved bobbin substantially as herein before described with reference to figures 5
and 6 of the drawings.
Fifthly. The arrangement or construction of a tubular spring substantially as
hereinbefore described with reference to figures 7, 8, 9 and 10, of the drawings.
Sixthly. The arrangement or construction of grooved sleeve and elastic hoop
substantially as herein before described with reference to figures 11 and 12 of the
drawings.
