Improvement in Ring and Traveller Spinning and Doubling Frames.
I THOMAS WRIGLEY of Waterside House, Todmorden in the County of York,
Manager, 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 ring and traveller spinning and doubling frames and
consists in an improved arrangement of mechanism or combination of parts for
preventing "ballooning" in the yarn while the ring rail is in its lower position.
On the sheet of drawings appended hereunto,
Fig. 1 shows a sectional side view of the ring frame with the improved mechanism
applied thereto,
Fig. 2 a front view of the same near to one end of the frame,
Figs. 3, 4 and 5 details.
On the drawings A denotes the yarn delivery rollers, B the thread board, C the
roller beam, D the ring rail, D' the rings, E the spindle rail, F the spindle bolsters,
and G the bobbins.
In carrying out my invention I arrange on each side of the machine near to
each end of the frame a short shaft a carried in brackets bb bolted to the
roller beam C or any other convenient part of the frame. Upon the end of
each shaft next to the frame end I fix a lever d (Figs. 2, 3,) in which two
holes are bored for bolts e e' provided with nuts and lock nuts to which bolts wires
or rods are attached that can be tightened or stretched by screwing up the
nuts e e. For resisting the pull of the wires, the bracket b' is only partly
bored through and the end of the shaft a made conical or with a centre point,
which bears against the end of the bore in bracket b¹ su that the shaft can
turn with little friction. Upon each shaft I fix another lever or finger g drilled
with two holes for the wire to pass through and formed with a tail g' which projects
downwards over the ring rail D. Similar fingers are arranged at intervals all
along the frame for supporting the wires. These fingers are mounted loosely on
studs i Figs. 4 and 5, the studs being fixed on brackets h which may be arranged
similarly as shewn on the drawings for bolting to the spring pieces of the frame,
or may be similar to brackets 6 b¹ and bolted to the roller beam C. The studs are
fixed in slots of brackets h, or the feet of the brackets are provided with slots, so
that they can be set forwards or backwards and the wires thereby set closer to or
farther away from the bobbins G. On the brackets h laterally projecting pegs ¹²
are cast for holding up the levers 9 in the position in which the wires are about
vertically above each other, or equivalent means may be used for this purpose.
Upon each shaft a a lever is fixed with laterally projecting peg which coming
against the bracket b' holds the fingers g on the shaft in the same position of the
wires. The wires are placed so as to be about mid way between the thread guide m
and the ring rail D when the latter is in its lowest position.
The different parts are in the positions shewn on the drawing while the ring
rail D is in its lower position, the wires ff' checking the tendency of the thread n
to fly outwards in consequence of its centrifugal force or "balloon" and causing it to
revolve round the spindle in the form indicated on the drawings. As the ring rail
rises, it encounters the ends g' of the fingers 9 and lifts them, turning the wires
backwards away from the spindle, as no check against ballooning is required in the
upper part of the lift of the ring rail, the fingers assuming the position shewn in
dotted lines on Fig. 1 when the ring rail is at the top of the lift. As it descends
again, the wires are successively brought closer to the spindles, the lower one first

rest. More than two wires or rods may be used.
I am aware that fixed and moveable rods or wires have been used before to check
ballooning and I do not claim the use of moveable rods or wires for this purpose
generally, but
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner it is to be performed, I declare that what I claim is
In ring and traveller spinning and doubling frames the arrangement of a short
shaft (a) near to each end of the frame carrying a lever (d), between which levers
two or more wires (ff') or rods are stretched, and fingers (g) supporting said wires
operated by the movement of the ring rail substantially as herein before described
and indicated on and by the drawings.
