Improvements in the Means for Holding and Regulating Bobbins,
Reels, or other similar Articles used for Holding Threads, Yarns,
or other such like Substances for Warping, Winding, and other
Purposes.
I EDWARD WARD COOPER of King Street Coventry in the County of Warwick
Machinist at Messrs. Dalton Barton & Co. Ltd. do hereby declare the nature of
my said invention to be as follows:-
My invention has for its object improvements in the means for holding and
regulating bobbins reels, or other similar articles used for holding threads yarns, or
other such like substances for warping winding and other purposes so that the
bobbins or reels are held in the racks or creels or other positions quite steadily or
firmly and with sufficient friction or tension while at the same time there is flexibility
of the parts and the bobbins or reels may be removed very quickly without difficulty
and as quickly replaced. The present method of holding bobbins by placing them
upon a wire rod either vertical or horizontal thus allowing them to revolve loosely
thereon as the thread or yarn is unwound is subject to variations and irregularities
which increases the amount of labour necessary and makes the work less reliable in
quality. For instance-The bobbin is free to run upon the spindle or rod loosely
and the tension is loose if the thread is taken direct and the bobbin overruns the
thread by its weight and there are loose & tight parts thereby caused in the winding.
Then the bobbin moves end wise and the flanges rub against the sides of the racks
ог " creels
thus causing the irregular tension and a jerking action especially if
the flanges of the bobbin are injured by notches and other defects which is often the
case. Further the holes in the bobbins wear irregularly and become oval or other
shape and thus they revolve with a jerking action. Now my invention remedies these
defects in a simple manner as follows.
"
I mount the bobbins or reels between two cone bearings which enter the hole at
each end and squeeze the bobbin or reel sufficiently endwise either by spring or
weight action to produce the desired tension and this may be (if necessary) regulated
by either an adjustable screw against a spring or by variation in weight. The simplest
form is to mount two bent springs by screws or other means to the racks or
"creels"
having internal cones at their inner ends and having a tendency to spring or press
inwards but which are sufficiently flexible to allow of being bent considerably or even
being reset without breaking to various lengths and conditions. By this means the
bobbins may be sprung in and out as quickly as possible and the tension increased
or decreased by a touch or bend of the springs and these may be placed either
horizontally or vertically or diagonally. The same effect may be produced by placing
the bobbin on rods or spindles having a fast cone at one end and a loose adjustable
cone at the other which may be regulated by either a spring or weight. By these
cones I avoid the rubbing of bobbin flanges against the racks or creels." By this
means any number of bobbins may be unwound at a time and passed on to a drum
bearer or any other appliance used to hold them in a uniformly compact manner.
The cones always have the tendency to wear the holes in the bobbins round and true.
The cones may be made of any metal such as cast iron wrought iron steel, brass, &c.
or of earthenware glass or other substance or material. By this means we often save
a process or processes in winding by being able to wind direct from the bobbins to
the beam.

I, EDWARD WARD COOPER of King Street Coventry in the County of Warwick
Machinist at Messrs. Dalton, Barton & Co. Ltd. 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 :—
My invention has for its object "Improvements in the means for holding and
regulating bobbins reels, or other similar articles used for holding threads, yarns or
other such like substances for warping, winding and other purposes so that the
bobbins or reels are held in the racks or creels or other positions quite steadily

were irregularly and become oval or other shape and thus they revolve with a jerking

each end and squeeze the bobbin or reel sufficiently endwise either by spring or
weight action to produced the desired tension and this may be (if necessary) be
regulated by either an adjustable screw against a spring or by variation in weight.

tension increased or decreased by a touch or bend of the springs, and these may be

produced by placing the bobbin on rods or spindles having a fast one at one end and
a loose adjustable cone at the other which may be regulated by either a spring or

manner.
In order that my invention may be clearly understood and more easily carried into
practice I have appended hereunto a double sized sheet of drawings upon which I
have illustrated the nature of my said improvements.
Figure 1 is an elevation of the reel or bobbin mounted in the rack B in accordance
with my said improvements.
Figure 2 is an end elevation of the same.

page_text: • Figure 3 is a longitudinal section through same.
Figure 4 is a longitudinal section through the reel A shewing a modification in the
mode of mounting it upon the spindle.
Figure 5 is an end elevation of same.
Figure 6 is a part elevation & part section of the spindle without the reel.
In carrying my invention into effect I mount the bobbins or reels A between the
two cone bearings D and D' which enter the hole a' at each end and squeeze the
bobbin or reel A sufficiently end wise by means of the two bent springs d² and d³ which
are secured to the rack or creel B. The springs d2 and d³ are sufficiently flexible
to allow of being bent considerably by which means the bobbins A may be readily
sprung in and out as quickly as possible and the tension increased or decreased by a
touch or bent of the springs d² & d³ in the direction shewn by dotted line in Figure 1.
The same effect may be produced by placing the bobbin A on the spindle E having
at one end the fast cone e¹ and the loose adjustable cone e which slides upon the
spindle at the other end and is regulated by the spring e³ which is in turn operated
upon more or less as may be required by the nut e by which means the spring is
made to bear more or less against the cone e² and thereby regulate the revolving of
the bobbin. The fast cone el is made to slide into a slot formed in the rack or creel B
the other end e of the spindle being placed in a hole or groove made to receive
it. The pressure upon the cones may be effected by weights instead of springs.
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 :-
1st. The improvements in the means for holding & regulating bobbin reels or
other similar articles used for holding threads yarns or other such like substances
for warping winding and other purposes substantially as and for the purpose herein
set forth and shewn.
2nd. The two bent springs d³ and d³ with their tits or cones D and D' substantially
as and for the purpose herein set forth.
3rd. The spindle E with its cones or tits e¹ and e² and adjustable springs e³
substantially as and for the purpose herein set forth.
