PROVISIONAL SPECIFICATION.
Improvements relating to Spinning and Doubling Frames.
I, JOSEPH HARGREAVES of 303 Halliwell Road, Bolton in the County of
Lancaster, Manager, do hereby declare the nature of my said invention to be as
follows:-
This invention refers to improvements relating to spinning and doubling frames
of the description set forth in my Patent Specification No. 15273 of 1891, and
consists in providing means for spinning and forming cops on the bare spindles.
In this arrangement each cop spindle is mounted loosely in its bearings and is
allowed to be pulled round or rotated by the action of the yarn as it is delivered
thereon by the flyer leg and.curl. If desired or necessary to have cops spun on
paper or other tubes, the latter may be placed on the spindle to rotate with the
same by the action of the yarn.

COMPLETE SPECIFICATION.
Improvements relating to Spinning and Doubling Frames.
I, JOSEPH HARGREAVES of 303 Halliwell Road, Bolton in the County of
Lancaster, Manager, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention refers to improvements relating to spinning and doubling frames
of the description set forth in any Patent Specification No. 15273 of 1891, and
consists in providing means for spinning and forming cops on the bare spindles.
In this arrangement each cop spindle is mounted loosely in its bearings and
is allowed to be pulled round or rotated by the action of the yarn as it is
delivered thereon by the flyer leg and curl. If desired or necessary to have
cops spun on paper or other tubes, the latter may be placed on the spindle to
rotate with the same by the action of the yarn.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side sectional elevation of my invention.
Fig. 2 is a front outside view of same, and
Fig. 3 is a plan of top guide.
A is the stationary or fixed bolster rail; B the lifting or traverse rail; C the
top guide rail; D the footstep; E the spindle tube; F the bolster; G the wharve,
and H the spindle.
In the lifting or traverse rail B is fixed the footstep D provided internally with
the groove I and the spring split ring K. The lifting or traverse rail B may be
operated by any of the well known or other copping motions. In the footstep D
is secured the spindle tube E by means of the spring split ring K, the latter
fitting in the annular groove or recess J in the spindle tube E and the groove I in
the said footstep. The spindle tube E may be secured in the footstep D by a set
screw in lieu of the spring split ring K. By means of the split spring ring K the
tube E may be readily removed therefrom or placed therein. The spindle tube E
slides up and down through the bolster F fixed in the bolster rail A. The bolster F
is secured to the stationary or fixed rail A by the nut O. On the tube F forming

page_text: part of the bolster F is mounted the tube M attached to the wharve G and the
disc N. Between the outside of the tube M and the inside of the outer portion
of the bolster F is provided the chamber or cavity L to receive oil or lubricant.
To the disc N are attached the standards or pillars P, secured at their upper end to the
ring Q. The latter is supported by the top guide R hinged to the rail C; the guide R
may be lifted for "doffing" and other purposes. The cop spindle H is mounted in the
tube E, being held in the upper end of the latter by the metallic or other bush S;
the lower end of the spindle H resting and rotating on the ball T composed of
either hardened steel or other metallic materials, glass or other suitable substances.
The ball T rests or sits on the spring U in the metallic or other tube V located
in the bottom end of the spindle tube E. The metallic or other tube V is fitted
at its lower end with cork or other pliable material to allow of an increased yielding
inotion as the cop W increases in size and weight, thereby minimising vibration.
The chamber or cavity between the outside of spindle H and the inside of tube E
is charged with oil to lubricate the spindle so as to allow of its being easily rotated
or pulled round by the action of the yarn as it is delivered thereon by the flyer
leg X and curl Y mounted on the ring Q. The ring Q is fitted with duplicate
flyer legs X and curls Y for the purpose of balancing the same.
The cop W may
be spun on the paper or other tube Z as shown in the drawings. The metallic or
other washer bis attached to the spindle H and is provided underneath with the
cork or other washer a, under which is disposed the spiral or cushion spring c in
the disc d mounted on the upper end of the tube E, by which an automatic "drag"
is effected as the weight of the cop W increases, thereby causing the yarn to be
wound on the cop at an uniform tension throughout the entire building of the same.
The disc N carrying the standards or pillars P and the ring Q are rotated by the
wharve G driven by a band from the ordinary tin or other driving cylinder.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
The general arrangement, construction, and combination of parts composing my
improvements in spinning and doubling frames, as hereinbefore described and as
illustrated in the annexed drawings.
