PROVISIONAL SPECIFICATION.
Improvements in the Construction of Rings and Travellers employed
in Ring-spinning and Ring-doubling Frames for Spinning and
Doubling Cotton and other Fibrous Substances.
We, BENJAMIN ALFRED DOBSON of Kay Street Works, Engineer, JOHN
HARGREAVES of 151 Deane Church Lane, Rumworth, Spinning Overlooker, and
EDWARD GILLOW of 325 Blackburn Road, Foreman Mechanic, all of Bolton in
the County of Lancaster, do hereby declare the nature of our said invention to be
as follows:-
This invention relates to improvements in the construction of rings and
travellers employed in ring-spinning and ring-doubling frames for spinning and
doubling cotton and other fibrous substances and is designed to produce rings
and travellers better adapted for spinning cops on the bare spindle than those
employed hitherto. Our improved ring is so constructed that the upper or lower
exterior diameter of the flange on which the traveller operates is larger than
elsewhere, and the upper or lower interior diameter of the said flange is smaller
than the diameter elsewhere, mounted on or attached to a central or other base
plate provided with a flange for fixing in the ring rail. Our improved traveller
is so constructed that the yarn is only once threaded or passed through the same
and wherein there is a guiding or winding bar so placed relatively to the positions
assumed by the traveller when the spindle is rotating or running in either direction
that the guiding or winding bar will in either case always be on the leading or
winding side of the centre of the spindle. This improved traveller is provided at
one end with prongs and a fork at the other end, these parts resting and travelling
on the flange of the ring. The prongs and the forked end are connected by means
of a bar or bars. By means of this traveller "twist" and "weft" may be spun on
the bare spindle without reversing the traveller. This invention is applicable for
spinning and doubling on tubes and the like.

COMPLETE SPECIFICATION.
Improvements in the Construction of Rings and Travellers employed
in Ring-spinning and Ring-doubling Frames for Spinning and
Doubling Cotton and other Fibrous Substances.
We, BENJAMIN ALFRED DOBSON, of Kay Street Works, Engineer, JOHN
HARGREAVES, of 151 Deane Church Lane, Rumworth, Spinning Overlooker, and
EDWARD GILLOW, of 325 Blackburn Road, Foreman Mechanic, all of Bolton,
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 improvements in rings and travellers employed in ring
frames for spinning and doubling cotton and other fibrous materials and the chief
object of our improvements is to produce rings and travellers better adapted for
spinning cops on the bare spindle than those employed hitherto.

page_text: We effect this object by constructing and arranging our improved rings and
travellers as illustrated on the accompanying sheet of drawings in which―
Figures 1 to 4 are four elevations of rings and travellers made according to our
improvements and applied to spindles of which Figs. 1 and 2 are running twist way
and Figs. 3 and 4 weft way as indicated by the arrows.
Fig. 5 is a sectional view showing the traveller in position on the ring and Fig. 6
is a view of the traveller detached.
In these views, A designates the spindle, B the yarn or thread, C the cop, D the
ring and E the traveller.
The traveller E is preferably stamped out of thin sheet steel but it may be
otherwise formed out of any other suitable metal. It has two straight prongs el
at one end connected by a bar e to two curved prongs e at the other end and both
sets of prongs e¹ e² take over and upon a flange d' on the ring D. The flange d
is preferably slightly undercut on the exterior so as to offer the minimum frictional
resistance to the curved prongs of the traveller E as the latter is carried round
either twist way or weft way by the drag of the yarn or thread B whilst the
spindle A is rotated. The yarn or thread B is brought from the delivery rollers
(not shown) and threaded once through the pair of open straight prongs e¹ and
thence on to the bare spindle A as shown or it may be on to a tube or bobbin
fixed on the spindle. The base or connecting bare of the prongs el forms the
yarn guiding or winding bar which, whether the spindle A is running either twist
way or weft way as indicated by the arrows, will always be on the leading side,
that is to say, the yarn guiding bar e will always be slightly in advance of the
axis of the spindle in the direction in which the spindle is running, this is clearly
shown in each of the views Figs. 1 to 5. The yarn guiding bar e assumes this
position automatically whether the spindle A is running twist way or weft way by:
reason of the drag of the yarn on it, and the play or freedom of movement
permitted by leaving sufficient space in the curved prongs e so that in one
direction the extremities of the curved ends of the prongs e² bear against the
exterior of the flange d' and in the other direction the interior portion of the
curved prongs e² at the point where they join the connecting bar bear against
the interior of the flange d'.
The chief advantages and features of novelty_in our improved ring and
traveller are that the yarn only requires once threading through the traveller, the
guiding bar e is always on the leading side of the axis of the spindle and lastly
the guiding bar assumes this position automatically, consequently the same
threading and either position of the traveller will answer equally well whether the
spindle is, running twist way or weft way.
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 :-
1. The combination with a flanged ring, of a traveller consisting of two sets of
prongs one straight and the other curved, the curved prongs engaging the flange on
the ring and having sufficient space within them to permit the yarn guiding bar
on the traveller to automatically assume a position on the leading side of the axis
of the spindle irrespective of the direction in which the spindle is running
substantially as specified.
2. The combination with the ring D having a flange d', of the traveller E
consisting of the pair of straight prongs el and curved prongs e² connecting bar e
and yarn guiding bar et all constructed, arranged and operating substantially as and
for the purposes herein set forth.
