Improvements in Certain Machinery for Spinning and Doubling
Cotton and other Fibrous Materials.
I WILLIAM ROBY SIDEBOTTOM of Heaton Norris near Stockport in the county
of Lancaster, Cotton Spinner, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a method of imparting rotary motion to the bobbins or tubos
used in certain machinery used for spinning and doubling cotton and other fibrous
materials.
According to my invention I provide the bobbin or tube with a parallel or cylindrical
or slightly conical surface or surfaces and I also provide the spindle with a cup or
other part formed with a parallel or cylindrical or slightly conical surface or parallel
or cylindrical or slightly conical surfaces upon or in which cup or upon or in which
parallel or cylindrical or slightly conical surface or surfaces the bobbin or tube may be
placed or rest, the parallel or cylindrical or slightly conical surfaces of the bobbin or
tube and of the spindle being so formed that the bobbin or tube will pass freely on to
the spindle.
The bobbin or tube is maintained in vertical position upon the spindle by resting
upon the cup or surface or surfaces above mentioned or by means of a collar or
equivalent therefor upon the spindle upon which collar or equivalent therefor the
bobbin or tube may rest.
The rotation of the spindle causes the bobbin or tube to be forced into contact
with the surface or surfaces with which the spindle is provided so that rotary motion
will be imparted to the bobbin or tube.
By my invention I am particularly enabled to employ in ring-spinning and ring-
doubling machinery bobbins or tubes provided with "heads" the cups or surfaces
or collars or equivalents therefor upon the spindles ensuring that the bobbins or tubes
shall be placed upon the spindles of the ring-spinning or ring-doubling machine at
an uniform height or in an uniform vertical position upon the spindles.

Improvements in Certain Machinery for Spinning and Doubling
Cotton and other Fibrous Materials.
I WILLIAM ROBY SIDEBOTTOM of Heaton Norris near Stockport in the county of
Lancaster, Cotton Spinner, 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:—
My invention relates to a method of imparting rotary motion to the bobbins or
tubes used in certain machinery used for spinning and doubling cotton and other
fibrous materials.
According to my invention I provide the bobbin or tube with a parallel or cylindrical
foot, surface or surfaces and I also provide the spindle with a cup or other part formed
with a parallel or cylindrical surface or parallel or cylindrical surfaces upon or in
which cup or upon or in which parallel or cylindrical surface or surfaces, the bobbin or
tube may be placed or rest, the parallel or cylindrical surfaces of the bobbin or tube
and of the spindle being so formed that the bobbin or tube will pass freely on

page_text: to the spindle and pass freely into the cup or over the hiss or collar as the case
may be.
The bobbins ortubes are maintained at an uniform vertical position upon the spindles
by resting upon tho cups or surfaces above mentionel or by means of collars or
equivalents therefor upon the spindles upon which collar- or equivalents therefor tho
bobbins or tubes may rest.
The rotation of the spindles causes the bobbius or tubes to be forced into contact
with the surfaces with which the spindles are provided, so that rotary motion will be
imparted to the bobbins or tubes.
By any invention I am particularly enabled to employ in ring-spinning and ring-
doubling machinery, bobbins or tubes provided with "heads or flanges" the cups or
surfaces or collars or equivalents therefor upon the spindles ensuring that the bobbins
or tubes shall be placed upon the spindles of the ring-spinning or ring-doubling
machine at an uniform height or in an uniform vertical prisition upon the spindles.
One arrangement of my invention is shown in Figs. 1 and 2. of the accompanying
drawing, Fig. 2. being a section taken on the plane indicated by the lino A.A of Fig. 1.
The tube I provide with a parallel or cylindrical foot or surface b. Fast upon the
spindle e 1 mount a cap d. The cup d I form with a part e, the internal surface of
which is formed parallel or cylindrical. [uto the cap the foot or surface b of the
tube a may be freely passed. The upper part of the tube az it so formed that sneh
part a' may be freely passed on to the top of the spindle c. The cup if I form with a
portion which forms a collar upon which the tube a rests.
The rotation of the spindle e causes the foot or surface 6 of the bobbiu a to be forced
into contact with the surface e of the cup of so that rotary motion will be imparted to
the bobbin a.
In Fig. 3. of the accompanying drawing my invention is shown as employed in
conjunction with bobbins formel with heads or flanges. To parts shown in Fig.3.which
correspond with parts shown in Figs. 1 and 2, I shall apply the same letters or
reference as are applied to the corresponding parts in Figs. 1 and 2. Upon the
spindle I mount a bobbin a provided with heads or flanges. The bobbin is also
provided with a foot or surface b which passes freely into the cup d. The bobbin is
supported by the edge of the cup (l. The rotation of the spindle cas in the arrange-
ment shown in Figs. 1 and 2 causes the foot or surface b of the bobbin a to be forced
into contact with the surface of the cup d so that rotary motion will be imparted to
the bobbin. By my invention I am enabled to ensure that the bobbins shall be placed
upon the spindles upon which they are to be employed at an uniform height and I am
thus enabled to " traverse" the yarn upon the entire length of the bobbin between the
heads or flanges a³, a thus avoiding the constant and great fluctuations in the speed
of the "traveller" which the "copping motion" involves, and without incurring anny
risk of the yarn being wound so as to leave a space at one end of the bobbin and
being wound upon the head or flange at the other end of the bobbin, as is the case
when the bobbins are not placed at an uniform height upon the spindles.
By being enabled to employ in ring-spinuing machines and ring-doubling machines
bobbins provided with heads or flanges I am enabled to wind or build a greater
quantity of yarn or thread upon a bobbin than cau be wound on a bobbin, 8001 or
tube without beads or flanges. In those cases in which the yarn or thread has to be
unwound from the bobbins by means of a winding machine, the unwinding can be
much more rapidly and economically accomplished whon the yarn or thread is wound
проц bobbins provided with heads or flangos than when the yaru or thread is wound
upon a spool or tubo without heads or flanges in the form of n cop.
The rotation of the spindle c by causing the foot or surface b of the hobbin to be
forced into contact with the surface e of the cup d not only causes the bobbin a to
be rotated but also causes such bobbin a to be held in position upon the spindle <
while such spindle c is rovolving.
Fig. 4 of the accompanying drawing shows an arrangement in which the bobbin a
instead of being provided with a foot or surface b capable of being passed freely into

page_text: a cup. d upon the spindle cas in the arrangements illustrated by Figs. 1. 2 and 3 is
provided with a foot b¹ passing freely outside a boss or collar fupon the spindle c which
boss or collar fis provided with a parallel or cylindrical part to act in conjunction
with a parallel or cylindrical part as formed in the bobbin a. As in the arrangements
above described the rotation of the spindle c will cause the part a' of the bobbin a to
be forced against the parallel or cylindrical part of the boss or collar / and rotated
and to be held in position upon the spindle c. The bobbin a shown in Fig. 4. of the
accompanying drawing is maintained in vertical position upon the spindle c by resting
upon a flange or collar y formed upon a part g¹ secured to the boss or collar fupon
the spindle c.
By the use of a loose tube or hobbin all risk of the spindles being strained in
'doffing" from the tubes or bobbins binding too tightly is avoided.
By adopting a parallel or cylindrical foot to the bobbin or tube and a parallel or
cylindrical cup or boss attached to the spindle, a loose bobbin or tube can be kept in
position and effectively driven in spinning and doubling cotton and other fibrous
materials on "ring frames" with the following advantages, viz. :-That the spindles
are not liable to be strained in "doffing" owing to bobbins or tubes binding too
tightly, that flanged bobbins can be used holding a much greater length of yarn,
reducing the frequency of "doffing" and reducing the cost of winding and that by
substituting the uniform "lift," of the full length between the flanges of the bobbin,
instead of the "copping motion lift," the rapid variation or fluctuation in the speed
of the "traveller is avoided.
"
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 herein before described method of maintaining loose bobbins or tubes in position
upon and imparting rotary motion to them by means of the spindles of machines for
spinning and doubling cotton and other fibrous materials which method consists in
so forming the bobbins orftubes and the spindles that when such a bobbin or tube is
placed in position upon such a spindle and such spindle is rotated the bobbin or
tube will be forced into contact with a part upon the spindle and have rotary motion
imparted to it and be kept in position upon the spindle by the rotation of such
spindle substantially as hereinbefore described.
