Improvements in or relating to Apparatus for Spinning and Doubling
Cotton and other Fibrous Substances.
We, THOMAS ASHWORTH, of Lynwood, Urmston, in the County of Lancaster,
Machinist, JOSEPH SHAW GAUNT, of Cromford Court, Yarn Merchant, and GEORGE
ANDREW ROBINSON, of 10, St. James Square, Accountant, both of Manchester, in
the County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
The invention relates to apparatus for the formation of cops of yarn upon bare
spindles (or on tubes fitted thereon) by mechanism similar to that for which Letters
Patent No. 20496 were granted to the said Thomas Ashworth, dated October 26th
1894, and the object of this invention is to improve the drag or brake applied to
the spindle and to simplify the doffing of the cops.
For this purpose, near to the fixed rail which carries the tubular flyers we
mount an excentric or oval shaft, or a series of cams on a shaft, carried by suitable
bearings and rotated at the required speed hereafter described, and on either side
of each bolster we fix a pin or peg diametrically opposite each other and parallel
with the shaft above described.
These pins or pegs serve as pivots, and upon each pair we hang a light frame
upon which we stretch a suitable piece of band of canvas or webbing, or other
suitable material which bears against the spindle passing through the bolster. If
desired a small quantity of oil or lubricant may be applied to this material on the
frame.
The frame may be arranged to cause the canvas or other material to bear on
either side of the spindle and may be made with an arm or arms weighted so as
to put a strong drag on one side of the spindle.
This arm extends over the shaft above named, the rotation of which is so timed
and speeded that the strong drag is applied as the yarn is wound on the larger
diameter of the cops, and the light drag as the yarn is wound on the spindle, and
the smallest diameter of the cop.
The weighted arm may be detached from the drag and bear upon a projection
therefrom, and in this case the light drag will be obtained from the weight of the
frame hanging with the canvas or other material against one side only of the
spindle; or instead of revolving the shaft may be made to oscillate to and fro,
and, in this case a weight may be fixed to a cord or band the other end of which
is fixed to this rocking shaft, this weighted end being passed round the spindle
and hanging over the shaft again.
When spinning on the bare spindle, the upper end of the said spindle is bored
down for a short distance, and the extremity of the tube so formed (which is very
thin) is notched or vandyked so as to leave a point, or two points, gradually
widening to about half the circumference of the tube, into which we then drive,
or fix tightly, a peg the end of which extends from the tube for a short distance
and forms the end of the spindle.
To attach the yarn the end is turned once or twice round the spindle, and drawn

page_text: down between one of the two points on the tube at the end thereof, and the
inserted peg, until it reaches or nearly reaches the root of the point, where it will
be held curved around about half the circumference of the spindle and will thus
be prevented from being drawn out lengthways.
The point of the tube will spring outwards sufficiently to allow of the insertion
of any ordinary count of yarn, which can also be readily removed by upward motion
in doffing.
When spinning on paper or other tubes the upper end of each tube is vandy ked
or made with a point and will act exactly like the point on the spindle itself,
which in this case may be plain as usual. In this case also the dofting of the yarn
will be quite easy, as the points will be removed with the cop.

Machinist, JOSEPII SHAW GAUNT, of Cromford Court, Yarn Merchant, and GEORGE
ANDREW ROBINSON, of 10, St. James' Square, Accountant, both of Manchester, in
the County of Lancaster, do hereby declare the nature of this invention and in

tained in and by the following statement:-

2.1
Ր
This invention relates to apparatus for the formation, of cops of yarn upon bare
spindles (or on tubes fitted thereon) by mechanism similar to that for which Letters
Patent No. 20,496 were granted to the said Thomas Ashworth, dated October 26th,
1894, and the objects of this invention are to improve the "drag" or brake applied
to the spindle and to simplify the doffing of the cops.
The invention will be readily understood on reference to the sheet of drawings
hereunto annexed and the following explanation thereof.
Fig. 1 is a partial side elevation of the spindle and flyer showing the application
of my present invention thereto. Fig. 2 is a partial back view thereof, and the
remaining figs. are detached views of slight modifications thereof hereinafter more
particularly referred to.
a is the spindle,
the cup-shaped tubular flyer, and c the wharve for driving
the same, d is the bolster carried in the fixed rail e of the frame.
For the purposes of our invention we mount near to the fixed rail e, a shaft f
which may be made excentric, or may be provided with a series of cams or excen-
trics (as shown at Figs. 1 and 1^) and this shaft f is rotated or caused to oscillate
to-and-fro at the required speed as hereafter described, and on either side of each
bolster d we fix a pin, peg or screw h diametrically opposite to each other, and
parallel to the shaft f above mentioned.
These pins or screws h serve as pivots on which we hang a light wire frame i
on which we stretch a small piece or band of canvas or webbing (as shown by the
dotted lines on Fig. 2) or a roll of felt (as shown at Fig. 2) or a tuft of cotton wool
or other suitable material (as shown at Figs. 1, 1, and 1") which material bears
against the spindle a passing through the bolster d the said material being satu-
rated with, or furnished with a suitable quantity or oil or other lubricant.
The upper part of the wire which forms the hanging frame, after curling round
the pins or screws h may be continued so as to form a light lever ¹ (as shown at
Figs. 1 and 1) the said lever being weighted if necessary so as to cause the canvas

page_text: or other material to press against, and thus put a "drag" upon the spindle a, or
the hanging frame i may be made with a short projecting arm (as shown at
Fig. 1) and the light lever k¹ may be made of a separate piece of wire curled
round the pin or screw h and resting on the short arm of the hanging frame.
The arms k¹ in either case extend over the shaft f, above named and rest upon
the cams or excentrics g thereon, and the rotation or oscillation of the shaft is so
timed and speeded that the support of the excentrics gradually withdrawn and
the weighted levers lowered so as to apply the strongest drag upon the yarn as
it is wound on the larger diameter of the cops and the lighter drag is applied as
the yarn is wound on the spindle, or on the smallest diameter of the cops.
"
In some cases when the shaft f is made to oscillate to-and-fro the above described
hanging frames i and light levers k¹ may be dispensed with and the varying "drag'
imparted to the spindles by the means represented by dotted lines at Fig. 1. In-
stead of the cams g a series of bosses are fixed on the shaft f and one end of a
cord m being attached thereto, by a screw or otherwise, the cord is carried partly
round the boss then brought forward in a loop round the spindle a (as shown)
then back again over the boss and to its other end the weight n is attached.
It will be evident that the oscillation to-and-fro of the shaft f will tend to raise
and lower the weight n and consequently to give the differential “drag” on the
spindle a.
When spinning upon the bare spindle the upper end of the said spindle is
bored down for a short distance as shown by the dotted lines on Fig. 1, and the
extremity of the tube so formed (which is very thin) is notched or vandyked, as
shown at o, so as to leave a point, or two points, gradually widening to about
half the circumference of the tube into which we then drive or fix tightly a pin
or peg the end of which extends for a short distance from the end of the spindle a.
To attach the yarn the end is turned once or twice round the spindle and drawn
down between one of the points of the tube and the inserted peg p until it reaches, or
nearly reaches the root of the point where it will be held curved round about half
the diameter of the spindle and will thus be prevented from being drawn out length-
ways. The points of the tube will spring outwards sufficiently to allow of the inser-
tion of any ordinary counts of yarn which can also be readily removed by an upward
motion in doffing.
Sometimes instead of boring down the top end of the spindle we reduce the
diameter thereof outside (as shown at Fig. 1) and we fix on this reduced end a
short tube or shell 9 which we notch or vandyke at the top in a similar manner.
When spinning cops on long paper or other tubes placed on the bare spindles
we notch or vandyke the upper ends of the tubes so as to form a point or points
thereon which will act in exactly the same manner. In this case also the doffing
of the yarn will be quite easy as the points will be removed with the cop.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what we
claim is:
First: The arrangements of mechanism substantially as herein before described
and illustrated for giving a differential " drag" to the spindle increasing as the
yarn is wound on to the larger diameter of the cop and decreasing in proportion
as the yarn is wound onto the smaller diameter of the same or on the spindle, and
Secondly, we claim the means herein before described and illustrated for enabling
the yarn to be attached to the spindle when commencing a fresh set of cops, and
detached therefrom when doffing the same.
