Improvements in Spindle Apparatus for Spinning and Doubling
Frames.
I, ROBERT WIGHTON MONCRIEFF, of Eakley Grange, Newport Pagnell, Bucks,
Techanical Engineer, do hereby declare the nature of this invention and in
hat manner the same is to be performed to be particularly described and
scertained in and by the following statement:-
This invention relates to certain improvements in spinning and doubling
rames and refers particularly to such frames wherein in lieu of the ordinary
tationary ring and revolving traveller there is employed a rotating ring held
n position centrically with the spinning or doubling spindle by horizontal
bullies or runners fixed on revolving spindles, and has primarily for object to
provide a means whereby the amount of drag for different counts of yarn may
be regulated or varied as required, and to prevent over-running of the rings
which are pulled round by the yarn going onto the spindle bobbin.
To accomplish this I make use of a ring constructed with a drag flange in
addition to the holding down flange or flanges and I bring up or extend the
centre spindle of one or more of the runner pullies so as to allow of a sleeved
weight disc being placed loosely on it, and pressing on the drag flange of the
spinning or doubling ring.
The amount of pressure is then regulated by annular weights of different
thickness being placed on top of the weight disc, which weights are readily.
removed therefrom, or spiral springs of various strengths may be employed in-
stead of the annular weights or in conjunction with them.
"
And in order that this invention may be fully understood I will now proceed
to describe same with reference to the accompanying sheet of drawings upon
which similar letters of reference indicate like parts in each of the figures.
Fig. 1 is an elevational view of a spindle fitted with a rotating ring with one
of its supporting pullies or runners carrying the drag regulating device before
referred to. Fig. 2 is an elevational view of the ordinary supporting pulley or
runner; and Fig. 3 is a diagram plan view to a smaller scale shewing several
of the rotating rings and their supporting pullies or runners.
a is the rotating ring which, as aforesaid, is formed with a drag flange 6 (sec
Fig. 1) as well as with the holding down flange c (there may be of course one
or more of these latter upon the ring). d is the spinning or doubling spindle,
and e the bobbin around which the rotating ring a is mounted. f is one of the
supporting pullies aforesaid which carries, in accordance with this invention,
5 the drag regulating device, now to be particularly described, and which is
particularly illustrated in Eig. 1 of the drawings.
g is the centre spindle revolving in the socket h and which is extended up-
wardly sufficiently to allow of the sleeved weight disc i being carried upon it.
This disc i may, when preferred, be faced on its lower side with leather or other
The disc i presses, as shewn, upon the drag
10 similar or suitable material.
k is an annular weight (shewn in section)
flange 6 of the rotating ring a.
hich is placed upon and carried by the weight dise i, and in accordance with

page_text: the weight or weights so applied is the amount of pressure varied or regulated
to suit requirements. These weights are readily affixed and removed, but in
lieu of their employment it will be obvious that spiral springs of different
strengths may be used, or said springs may be employed in conjunction with the
weights.
The holding down flange c of the ring a comes up against the flange f¹ of
the hooded or flanged runner pulley f and as the spindles of the runner pullies
are collared at bottom in the sockets, the upward pull of the yarn is resisted
by them and there is consequently no upward pull on the weight disc i which
revolves with, and is rotated by, the ring a as it is revolved by the yarn 7 going
onto the spindle bobbin e. The guide or hook for the yarn upon the ring a is
indicated by the letter m, the ring plate by the letter n, and o indicates the
driving wharfe. p p (Figs. 2 and 3) are the ordinary hooded or flanged runner
pullies and which act as supports to the rotating rings a.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is―
1. In spinning and doubling frames, wherein a rotating ring and horizontal
revolving supporting pullies or runners are employed in lieu of a stationary
ring and a revolving traveller, the device for regulating or varying the drag,
and preventing over running of the rotating rings; substantially as herein
described and shewn.
2. In spinning and doubling frames, wherein a rotating ring and horizontal
revolving supporting pullies or runners are employed in lieu of a stationary
ring and a revolving traveller, the revolving ring a formed with a drag flange b
and the sleeved weight disc i carried upon the extended pulley or runner
spindle g, in combination with a regulating weight or weights k or equivalent
pressure applying media, constructed, arranged, and operating substantially as
and for the purpose specified.
