I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN RING AND TRAVELLER SPINNING FRAMES' a communication to me from abroad
by Jean Jacques Bourcart of Zurich, Switzerland, to be as follows :—

•
This Invention relates to improvements in ring and traveller spinning frames,
and it has for its object to prevent the breakage of the yarns and the marrying or
running double of the broken ends with the adjoining yarns.
The improvements, which are applicable to any description of spindle, relate to
a fixed yarn guide; a bolster of polygonal form externally, a hook for removing
the broken 'end fixed near the tip of the spindle and a split ring holder adjustable
horizontally.
The improvements are illustrated in the accompanying drawings as applied to a
spindle with a ring and traveller on the Bourcart system which form however no
part of the Invention except as regards their combination with tho now parts
constituting its essential foatures.
Figure 1 is a longitudinal section of a spindle with the improvements applied.
Figure 2 is a cross section of the polygonal bolster. Figure 3 is a plan of the ring
holder.
The bolster A is made of square or polygonal form at the part where it is fitted
in or upon the bolster carrier B, which is made of corresponding form to receive it
loosely and prevent it from turning. The foot C of the spindle X revolves upon a
pivot C movable in a suitable footstep D. The ring and traveller may be of any
suitable kind, the arrangement shown being that described in a former patent.
The ring holder E is fixed by a screw F or its equivalent to a rail G carried by the
lifting rod M and is horizontally adjustable thereon in any direction. This
adjustable holder E may either consist of a closed or split ring or be formed simply
of wire bent to a circular form. A single or double hook H (figure 1) separates
the yarns of adjacent bobbins, and is placed immediately above the point of the
spindle and between it and the movable yarn guide L, its function being to catch
broken ends and prevent their running double with the adjoining yarns. Above

page_text: the movable yarn guido is placed a fixed yarn guido I either formed of a piece of
sheet iron having a slit in it, a wire fork or their equivalent; it guides the yarn
laterally and also serves to prevent the broken ends coming from the front rollers N
running double with the adjacent yurns the ends instead of floating as usual
remaining above and accumulating upon said guide. The lifting rods M figuro 1
are supported in one or more guides as usual and they are coupled together two
and two or in greater number at bottom by a rail K by which the copping motion
is imparted in the usual manner such as by a series of levers &°. The yarn y passes
from the rollers N between the limbs of the fork I, over the thread board L down
beside the hook H without touching it and then through the traveller T to the
spindle X upon which it is wound. If a yarn breaks, tho untwisted portion
coming from the front rollers, accumulates above the fixed guide I until it becomes
wound upon the cleaning roller O or its equivalent; while the twisted portion
which forms a tuft upon the tip of the spindle X becomes caught and broken off
by the hook H thereby preventing its entanglement with the adjacent yarns.
The ringholder E can be readily adjusted so as to make the ring truly concentric
with the spindle but if the latter should be liable notwithstanding the care taken
in its construction to vibrate, there would be a quantity of broken yarn at the
termination of the lift, and to remedy this tho bolster is made square or polygonal
and fits loosely into a cavity of corresponding form in the bolster holder. Or the
bolster may be only partly polygonal, or a partly polygonal socket may be used
with an ordinary bolster, or the bolster may be free to move in every direction
except that of rotation, all these arrangements being equivalents which may be
substituted for one another.
The spindle X in its rotation tends to carry with it the bolster A which finds a
bearing against the holder B or its equivalent and having play in this holder it
takes up a skew position, while still remaining central. If under these conditions
the spindle should vibrate from any cause, the bolster will move to one side for an
instant, but owing to its tendency to rotation it immediately centres itself and
thus prevents vibration of the spindle and the consequent breakage of the yarn.
It is evident that the same arrangement may be adapted to the footstep and bo
modified in many ways, only in this case if the bolster be united with the footstep,
thero would only be the bolster free in its holder. -

I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN RING AND TRAVELLER SPINNING FRAMES" (a communication to me from abroad
by Jean Jacques Bourcart of Zurich, Switzerland) and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:-
This Invention relates to improvements in ring and traveller spinning frames,
and it has for its object to prevent the breakage of the yarns and the marrying or
running double of the broken ends with the adjoining yarns.
The improvements, which are applicable to any description of spindle, relate to
a fixed yarn guide; a non elastic bolster of polygonal forin externally fitting in an
adjustable part, a hook for removing the broken end, independent of the yarn
guides and fixed near the tip of the spindle and a split ring holder adjustablo
horizontally.
The improvements are illustrated in the accompanying drawings as applied to a
spindle with a ring and traveller on the Bourcart system which form however no
part of the Invention except as regards their combination with the new parts
constituting its essential features.
Figure 1 is a longitudinal section of a spindle with the improvements applied.
Figure 2 is a cross section of the polygonal bolster. Figure 3 is a plan of the ring
holder.
The bolster A figures 1 and 2 is made of polygonal form externally at the part
where it is fitted in or upon the bolster carrier B which is made of corresponding
form to receive it and prevent it from turning and is adjustably mounted upon one
of the spindle rails it being shown in the drawing as mounted upon the footstep
rail. The foot of the spindle ✗ revolves upon a pivot C movable or not in a
suitable footstep D. The ring R and traveller T may be of any suitable kind the
arrangement shown being that described in a former patent and the spindle wharve
may overhang the footstep if desired. The ringholder E which is not concentric
with the ring is fixed by a screw F or its equivalent to a rail G carried by the
lifting rod M and is horizontally adjustable thereon in any direction. This
adjustable holder E may either consist of a split ring or be formed simply of wire
bent to a circular form and clamped by means of a nut and washer or otherwise.
A single or double hook H (figure 1) or a strip of card clothing extending the
length of the machine is placed immediately above the point of the spindle and
between it and the movable yarn guide L that is to say independent of any yarn
guide, its function being to catch broken ends and prevent their running double
with the adjoining yarns. Above the movable yarn guide is placed a fixed yarn
guide. I either formed of a piece of sheet iron having a slit in it, a wire fork or

page_text: their equivalent; it guides the yarn laterally and also serves to prevent the broken
ends coming from the front rollers N running double with the adjacent yarns, the
ends instead of floating as usual remaining above and accumulating upon said
guide. The lifting rods M figure 1 are supported in one or more guides as usual
and they are coupled together two and two or in greater number at bottom by a
rail K by which the copping motion is imparted in the usual manner such as by a
series of levers &c. The yarn y passes from the rollers. N. between the limbs of
the fork I, over the thread board L-down beside the hook H without touching it
and then through the traveller T to the spindle X upon which it is wound. If a
yarn breaks, the untwisted portion coming from the front rollers accumulates
above the fixed guide I until it becomes wound upon the cleaning roller O or its
equivalent; while the twisted portion which forms a tuft upon the tip of the
spindle X becomes caught and broken off by the hook H thereby preventing its
entanglement with the adjacent yarns.
In order that the spindle E may revolve exactly in the centre of tho ring, as
otherwise the yarn would be continually breaking, the ringholder E can be readily
adjusted after loosening screw F and the ring made truly concentric to the spindle
and tightened again but if the latter should be liable, notwithstanding the care
taken in its construction to vibrate, there would be a quantity of broken yarn at
the termination of the lift, and it is to remedy this the bolster is made polygonal
and fitted loosely in a mortise or cavity of approximately corresponding form in
the bolster holder. Or this adjustable bolster may be only partly polygonal, or a
partly polygonal socket may be used with an ordinary adjustable bolster, all theso
arrangements being equivalents which may be substituted one for the other.
The spindle X in its rotation tends to carry with it the bolster A which finds a
bearing against the holder B or its equivalent and having play in this holder it
takes up a skew position, while still remaining central. If under these conditions
the spindle should vibrate from any cause, the bolster will move to one side for an
instant, but owing to its tendency to rotate it immediately centres itself and thus
prevents vibration of the spindle and the consequent breakage of the yarn. It is
evident that the same arrangement may be adapted to the footstep even when the
wharve is opposite the bolster and be modified in many ways, but in this case if
the bolster be united with the footstep, there would only be tho bolster free in its
holder.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, I would observe
that I make no claim to the bolster, hook or adjustable ring, as such were invented
the first by Vimont in 1850, the second by Tweedale in 1861, and the third by
Wright in 1836 and have since been improved on by other inventors, but what
I claim as the improvements in ring and traveller spiuning frames hereinbefore
described, having for object to prevent or render less frequent the breaking of the
yarn in consequence of the vibration of the spindle and its defective centering in
the ring; also to prevent the broken ends whether on the spindle or coming from
the front rollers from marrying with the adjacent yarns is
1st A bolster made of polygonal form externally and fitting without any clastic
intermediary in or upon a bolster holder of corresponding form adjustably fitted
to the spindle rail or their equivalents, in combination with a ring and traveller as
and for the purpose specified.
2nd The fixed yarn guides below the front rollers having the form either of a
fork or slitted plate in the bottom of which the yarn does not rub or their
equivalents, in combination with rings and travellers and a yarn guide which is
movable with or remains at an invariable distanco from the ring for the purpose
specified.
3rd The fixed yarn breaker independent of the yarn guides placed near the top
of the spindle as described and represented or its equivalent in combination with a

page_text: ring and traveller and movable yarn guide or its equivalent for the purpose
specified.
4th The split ring holder adjustable horizontally as shown and described for the
purpose specified.
5th The general combination of parts or their equivalents as shown and
described.
