PROVISIONAL SPECIFICATION.
Improvements in Spinning and Doubling Frames.
ROBERT WIGHTON MONCRIEFF, Eakley Grange, near Newport Pagnell, Bucks,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
In place of the ordinary stationary ring and revolving traveller I employ a
rotating ring held in proper vertical position centrically with the spinning or
doubling spindle by three or other suitable number of grooved horizontal
pullies or runners fixed on spindles revolving by preference vertically in dust
proof oil sockets similar to those in general use for high-speed spindles in the
cotton trade.
The said grooved pullies or runners are arranged around the periphery of
the rotating ring and in contact with it at such points as may be convenient,
but preferably at equal distances, and the spindle sockets of same are fixed into
the traverse rail or ring-plate, so that the rotating ring is caused by means of
the grooved pullies to ascend and descend along with said traverse rail.
The edge of the ring being shaped to correspond with and fit into the grooves
of the said pullies, or the ring may be grooved and the pullies shaped to fit into
it; in either case in such manner as to resist the upward pull on the ring caused
by the strain of the yarn that is being twisted.
The spindles of the grooved pullies must also be collared or otherwise con-
structed or arranged to resist the same upward pull.
The rotating ring and its surrounding pullies may have several grooves and
corresponding ridges, and may be constructed of hardened steel or other suitable
material.
An eye-hole or a series of eye-holes is bored thro' the rotating ring with a
suitable slit or passage for the introduction of the yarn or ends to be twisted,
or a separate hook or guide for the yarn may be inserted in or round the ring so
as to be detachable when expedient.
The above specified rotary ring is rotated by the yarn from the spindle bobbin
pulling it round.
The spindle bobbin being fixed on a revolving central spindle driven by a
band &c. in the ordinary manner.
The rotating ring in its turn causes the grooved pullies or runners to revolve
and the force required to do this provides the requisite drag on the yarn being
twisted and ensures its winding on to the spindle bobbin without ballooning.
The ring and its surrounding pullies are made of such suitable dimensions,
forms and weights as may be necessary for various counts, qualities and
descriptions of yarn: and for heavy counts the ring may be grooved on its
periphery for the reception of a weighted temper-band, or one of the surround-
ing pullies may be thus dragged, in which case the spindle socket of such pulley
would he placed in a slot in the traverse rail, so that its periphery would he

page_text: pulled against the rotating ring; or a spring may be used to effect the same
object.
To allow of different counts of yarn being twisted on the same frame the holes
for the sockets of the runner pullies may be slotted radially from the ring centre,
so that rings of different dimensions can be worked on the same ring-plate by
setting these runner pullies nearer or farther from their common centre.
When desired the ordinary knee-brake may be fitted so as to act on the rotating
ring and retard its motion simultaneously with that of the bobbin spindle,

Improvements in Spinning and Doubling Frames.
I, ROBERT WIGHTON MONCRIEFF, of Eakley Grange, near Newport Pagnell,
Bucks, Mechanical Engineer, 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:-
In place of the ordinary stationary ring and revolving traveller, I employ a
rotating ring held in proper vertical position centrically with the spinning or
doubling spindle by three or other suitable number of grooved horizontal
pullies or runners fixed on spindles revolving by preference vertically in dust-
proof oil sockets, similar to those in general use for high speed spindles in the
cotton trade.
The said grooved pullies or runners are arranged around the periphery of
the rotating ring and in contact with it at such points as may be convenient,
but preferably at equal distances, and the spindle-sockets of same are fixed into
the traverse rail or ring plate, so that the rotating ring is caused, by means of
the grooved pullies, to ascend along with said traverse rail.
The edge of the ring being shaped to correspond with and fit into the grooves
of the said pullies, or the ring may be grooved and the pullies shaped to fit into
it; in either case in such manner as to resist the upward pull on the ring caused
by the strain of the yarn that is being twisted.
The spindles of the grooved pullies must also be collared or otherwise con-
structed or arranged to resist the same upward pull.
The rotating ring and its surrounding pullies may have several grooves and
corresponding ridges and may be constructed of hardened steel or other suitable
material.
An eye-hole or a series of eye-holes is bored through the rotating ring with a
suitable slit or passage for the introduction of the yarn or ends to be twisted,
or a separate hook or guide for the yarn may be inserted in or around the ring so
as to be detachable when expedient.
The above specified rotary ring is rotated by the yarn from the spindle bobbin
or tube pulling it round; the spindle bobbin or tube being fixed on a revolving
central spindle driven by a band &c. in the ordinary manner.
The rotating ring in its turn causes the grooved pullies or runners to revolve
and the force required to do this provides the requisite drag on the yarn being
twisted, and ensures its winding on to the spindle bobbin without ballooning.
The ring and its surrounding pullies are made of such suitable dimensions,
forms, and weights as may be necessary for various counts, qualities and
descriptions of yarns; and for heavy counts the ring may be grooved on its
periphery for the reception of a weighted temper-band, or one of the surround-
ing pullies may be thus dragged, in which case the spindle-socket of such pulley

page_text: would be placed in a slot in the traverse-rail, so that its periphery would be
pulled against the rotating ring, or a spring may be used to effect the same
object.
To allow of different counts of yarn being twisted on the same frame, the holes
for the sockets of the runner pullies may be slotted radially from the ring centre,
so that rings of different dimensions can be worked on the same ring-plate, by
setting these runner pullies nearer or further from their common centre.
And in order that this invention may be fully understood and readily carried
into effect I will now describe same with reference to the accompanying drawings
upon which Fig. 1 represents in elevational view a spindle fitted with the
rotating ring and its supporting pullies or runners, (one of the latter being shewn
in section to more clearly illustrate the preferred manner of fixing same upon its
spindle which revolves in an oil socket). Fig. 2 is a plan of same; Figs. 3 and 4
are diagrammatic plan views of a series of rotating rings and their supporting
pullies, and Figs. 5, 6, 7, 8, 9 and 10 are detail views of various constructions
of the rotating ring. Figs. 5, 6, & 7 being side views of said rotating ring
shaped so as to fit into the groove upon each supporting pulley. Figs. 8 & 9
are side views of the rotating ring shaped so that the supporting pullies take into
the groove formed upon the periphery of the rotating ring. Fig. 10 is a side
view of the ring formed with a groove and a projecting shoulder. Similar letters
of reference indicate like parts in each of the figures wherever occurring.
a is a rotating ring which as aforesaid I employ with its supporting pullies
in place of the ordinary stationary ring and revolving traveller. 6 is the spinning
or doubling spindle around which and the bobbin or tube the ring a is mounted.
Fig. 1 representing the spindle bobbin.
e are the horizontal pullies or runners which hold the rotating ring a in its
proper vertical position centrically with the spindle b. These pullies or runners c
are fixed on spindles d which revolve by preference vertically in dust-proof oil
sockets e (see Fig. 1) and are as above mentioned similar to those in general use
for high speed spindles in the cotton trade. f Fig. 1 is the traverse rail into
which the spindle sockets e are fixed so that the rotating ring a is caused by means
of the pullies e to ascend or descend along with said traverse rail. The pullies c
are arranged as shown around the periphery of the rotating ring a (see particu-
larly Figs. 2, 3 and 4) and in contact with it at such points as may be convenient,
but preferably at equal distances, and either the pullies may be grooved as shewn
at e (Fig. 1) and the edge of the rotating ring a shaped to correspond with, or
fit into, the grooves of the pullies, or the ring a may be grooved and the pullies
shaped to fit into it; in either case in such manner as to resist the upward pull
on the ring caused by the strain of the yarn 9 (Figs. 1 and 2).
is a hook or guide for the yarn arranged or placed in or round the ring a so
as to be detachable when desired, (see Figs. 1, 2, 3, 5, and 7,) and i (Fig. 7)
shews the arrangement of the alternative eye-holes (or there may be a series of
same) bored through the rotating ring a with a suitable slit or passage (see
also Fig. 8) for the introduction of the yarn or ends to be twisted. The spindle
bobbin is fixed upon the revolving central spindle b which is driven by a
band Fig. 1 and pulley in the ordinary manner.
The rotating ring a is pulled round by the yarn and in its turn causes the
pullies or runners to revolve, and the force required to do this provides the
requisite drag on the yarn being twisted and ensures its winding on to the spindle
bobbin without ballooning. Several hooks h or guides may be placed at
different points round the rotating ring a so that the end may be taken
through or round more than one when advisable.

Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is
1. In spinning and doubling frames, the rotating ring a and horizontal

page_text: pullies ce arranged, constructed and operating substantially as and for the pur-
poses described herein and shewn in the accompanying drawings.
2. In spinning and doubling frames, the rotating ring a with hook or hooks h,
eyeholes and slit or passage k, spindle bobbin 61, spinning or doubling spindle b,
horizontal pullies e, pulley spindles d, spindle sockets e and traverse rail f, all
constructed combined, arranged and operating substantially as shewn and
described.
