Improvements in Bobbins for Sewing Machines and for other uses,
and in the Method of Winding the same.
I ALFRED BRYANT MORSE, of South Easton, in the State of Massachusetts, one
of the United States of America, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
__;
My invention is an improved method of winding bobbins, whereby a perfectly
wound bobbin is insured, and whereby also a bobbin of any degree of thinness
relatively to its depth may be produced.
Heretofore, bobbins (and by that. term I mean a wound body of thread whether
the same be called by the name of cop, bobbin or any other name) have invariably
been wound singly, usually one machine having six spindles so that at one wind-
ing six individual and entirely distinct bobbins might be wound; but this individual
winding has many disadvantages, particularly so in the case of thread wound for
the shuttles of sewing machines.
It is desirable to use machine-wound bobbins for sewing machines, the bobbin
being placed between the separable sides of the shuttle, because much more thread
can be carried by the shuttle in this way than if the thread were wound directly
on the shuttle, and also it saves a great amount of time, labor, and expense.
In order to produce perfect bobbins, it has usually been the custom to wind
the thread between discs or heads placed on the spindle of the machine to hold
the thread from irregular winding at the ends of the bobbin, and in order to produce
smooth, regular end surfaces.
My invention enables me to wind any number of bobbins with absolutely perfect
and unvarying winding from the beginning to the finish, and it enables me to
do this winding with a great saving of time, expense, labor, and waste; it also
cuables me to introduce a range of novel effects and combinations of grades and
colors of threads, which have not been heretofore possible; and it thereby enables
me to produce a novel and useful product which also I include in my invention,
as hereinafter more particularly set forth.
My invention prevents the ends of the bobbins from having flaws, and enables
me to wind the bobbin with unusual solidity, and makes it practical to wind
extremely thin or narrow bobbins with the absolute certainty that they will be
perfect, and as dense and accurate as though they were large and wide and wound
in the usual way.
My method consists, in general terms, in winding on one spindle simultaneously
and immediately contiguous one to another the desired plurality of bobbins,
whereby there is built up a plurality of homogeneous discs, each of which con-
stitutes a hobbin, the whole, however, being built up in one solid thread mass,
so that as a result each disc or bobbin acts as a guide for the one next to it and the
several bobbins act as supports for each other, enabling the winding to progress
evenly and rapidly and permitting the bobbins or discs to be as thin or narrow as
may be without the slightest danger of any uncertainty or irregularity in the wind-
ing, it being thus possible to make thin bobbins as readily as thick ones, inasmuch

page_text: as the throw of the thread guide makes no difference whatever with the per-
manency or integrity of the bobbin, for the reason that all the bobbins support
one another with the same effect as if they were actually one bobbin and not several.
Preferably each bobbin will have its own spool or annular foundation, the
several spools or foundations together constituting one extended cylinder, thimble,
or spool, extending from end to end of the thread mass, and this cylinder may be
made up of a plurality of rings of paper placed on the spindle of the machine
before the winding and clamped snugly against each other so as to form one un-
interrupted tubular foundation to receive the several threads, or it may be a single
integral tube of the required length, scored circumferentially at the points of
breakage or cleavage, where the individual bobbins leave off, i.e., it may be
circumferentially grooved or cut nearly through so that it may readily separato
whenever the several bobbins are pried off from the thread mass; preferably this
foundation or spool will be made of paper, although I do not limit myself in respect
to material.
The bobbins may be packed and sold in masses as wound, that is, in coherent
packages of sixteen or of whatever number is preferred, and when it is desired
to use a bobbin, a paper knife or other thin wedge is forced down between the inner
edge of the bobbin and the adjacent thread mass, thereby prying off the complete
bobbin and disrupting or separating its foundation ring from the rest of the
tube.
The result is that a dense, and unusually perfect and accurate bobbin is pro-
duced; moreover, the several bobbins being compacted, as described, into one
solid mass, which is not easily separated into its constituent bobbins, materially
aids in packing and shipping the bobbins, also enabling the latter to be kept com-
pactly and without liability of becoming soiled or injured.
I have thus far described the bobbin and my improved method of winding in
their general features; a further novelty and exceedingly advantageous feature
thereof resides in the capability thereby afforded of winding the successive bobbins
in varying colors or shades of threads, for use in sewing or stitching, or it may be
for twisting, braiding, or weaving in different colors.

Improvements in Bobbins for Sewing Machines and for other uses,
and in the Method of Winding the same.
I ALFRED BRYANT MORSE, of South Easton, in the State of Massachusetts one
of the United States of America, Manufacturer 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 is an improved method of winding bobbins, whereby a perfectly
wound bobbin is insured, and whereby also a bobbin of any degree of thinness
relatively to its depth may be produced.
Heretofore, bobbins (and by that. term I mean a wound body of thread whether
the same be called by the name of cop, bobbin or any other name) have invariably
been wound singly, usually one machine having six spindles so that at one wind-
ing six individual and entirely distinct bobbins might be wound; but this individual

the shuttles of sewing machines.
t
It is desirable to use machine-wound bobbins for sewing machines, the bobbin
being placed between the separable sides of the shuttle, because much more thread
can be carried by the shuttle in this way than if the thread were wound directly
on the shuttle, and also it saves a great amount of time, labor, and expense.
In order to produce perfect bobbins, it has usually been the custom to wind
the thread between discs or heads placed on the spindle of the machine to hold
the thread from irregular winding at the ends of the bobbin, and in order to produce
smooth, regular end surfaces.
My invention enables me to wind any number of bobbins with absolutely perfect
and unvarying winding from the beginning to the finish, and it enables me to
do this winding with a great saving of time, expense, labor, and waste; it also
enables me to introduce a range of novel effects and combinations of guades and
colors of threads, which have not been heretofore possible; and it thereby enables
me to produce a novel and useful product which also I include in my invention,
as hereinafter more particularly set forth.
The details of my invention both as to the method, and the new and improved
article resulting therefrom, will be fully described in the following specification
and more particularly defined in the appended claims forming a part of the speci-
fication, reference being had to the accompanying drawings illustrative of my
invention.
In the drawings Fig 1 in perspective shows a plurality of bobbins, wound
according to my improved method, illustrating the manner of winding.
Fig 2 is a front elevation thereof, one of the bobbins being removed from the
rest in order to more clearly indicate the results of my method.
Fig 3 is a central, vertical, longitudinal section.
In the usual winding of bobbins it is customary to start one thread for a single
bobbin on each spindle of the machine, this thread being built up in varying ways
according to the different machines in use, the bobbin, however, in every case being
single and distinct by itself and one only being produced at a time on a spindle,
this one bobbin having its ends liable to frequent flaws in the winding and,
moreover, while this single winding is practical and reasonably accurate for winding
large bobbins or hobbins of considerable relative width, it is not practical for
extremely thin or narrow bobbins, such as those herein shown, see particularly
Fig 2.
By my invention I can produce a hobbin as thin as desired, with the absolute
certainty that its winding will be perfect and that it will be as dense and accurate
as though it were a large and wide bobbin, the drawings herein showing in full size
bobbins wound by my method, and it is feasible to produce perfect bobbins much
thinner and of larger diameter than those herein shown, if desired.
My method consists, in general terms, in winding on one spindle simultaneously
and immediately contiguous one to another the desired plurality of bobbins,
whereby there is built up a plurality of homogeneous discs, each of which con-
stitutes a bobbin, the whole, however, being built up in one solid thread mass,
as shown in Fig 1, so that as a result each disc or bobbin acts as a guide for the
one next to it and the several bobbins act as supports for each other, enabling
the winding to progress evenly and rapidly, and permitting the bobbins or discs to
be as thin or narrow as may be, without the slightest danger of any uncertainty
or irregularity in the winding, it being thus possible to make thin bobbins as
readily as thick ones, inasmuch as the throw of the thread guide makes no difference
whatever with the permanency, or integrity of the bobbin, for the reason that all
the bobbins support one another with the same effect as if they were actually one
bobbin and not several.
In the drawings I have shown a thread mass A, comprising sixteen bobbins a
which have been wound together on one spindle, the thread ends a¹ being shown
in Fig 2 for clearness of understanding. Preferably each bobbin will have its

page_text: own spool or annular foundation b, the several spools or foundations together con-
stituting one extended cylinder, thimble, or spool B, as clearly shown in Fig 3,
extending from end to end of the thread mass, and this cylinder may be made up of
a plurality of rings of paper placed on the spindle of the machine before the winding
and clamped snugly against each other so as to, form one uninterrupted tubular
foundation to receive the several threads, (sixteen in the instance supposed and illus-
trated), or it may be a single integral tube of the required length, scored circum-
ferentially at the points of breakage or cleavage, where the individual bobbins
leave off, .e., it may be circumferentially grooved or cut nearly through so that
it may readily separate whenever the several bobbins are pried off from the thread
mass; preferably this foundation or spool B will be made of paper, although I
do not limit myself in respect to material.
In winding the bobbins the threads a are accurately spaced apart distances
corresponding to the desired thickness of the bobbins to be wound, the thread guide
being given a corresponding throw, and, the threads having been started on their
respective rings or annular foundations of the tube B, the several bobbins
simultaneously build up contiguous to each other and with a resulting firmness
and solidity that renders the entire mass perfectly homogeneous and coherent.
In fact, the threads mat and weld together, as it were, at the sides or ends of the
bobbins as the latter build up, so that the mass formed by the plurality of bobbins
has a
resulting firmness and solidity which offers considerable resistance to the
separation of the completed bobbins, one from another.
The bobbins may be packed and sold in masses as wound, that is, in coherent
packages of sixteen or of whatever number is preferred, and when it is desired
to use a bobbin, a paper knife or other thin wedge is forced down between the inner
edge of the bobbin and the adjacent thread mass, thereby prying off the complete
bobbin and disrupting or separating its foundation ring from the rest of the
tube B.
The result is that a dense, and unusually perfect. and accurate bobbin is produced,
as shown at the right hand in Fig 2; moreover, the several bobbins being com-
pacted, as described, into one solid mass, which is not easily separated into its
constituent hobbins, materially aids in packing and shipping the bobbins, also
enabling the latter to be kept compactly and without liability of becoming soiled or
injured.
I have thus far described the bobbin and my improved method of winding in
their general features; a further novelty and exceedingly advantageous feature
thereof resides in the capability thereby afforded of winding the successive bobbins
in varying colours or shades of thread, as indicated in Fig 1, by the different
circumferential stripes. This feature produces surprisingly beautiful effects in
the composite product; and if desired, two or more threads and colors may be
wound in each hobbin.
This is of practical advantage in enabling several threads to be fed from one
bebin in sewing, for instance in different colors, and enabling stitching to be
done, if desired, with a plurality of needles fed from one bobbin, or enables the
several colors all to be fed under equal resistance or tension from the one bobbin
or thread mass to one needle or point of delivery (it may be for twisting, braiding,
or weaving).
It is obvious that not only are superior bobbins produced by my method of wind-
ing, this being especially the care where thin and large diameter bobbins are
wound, but also an immense saving of labor und expense is effected; the further
practical advantage is secured that a greatly increased output may be had from the
same number of winding machines; whereas, heretofore it has been possible
merely to wind one bobbin on a spindle, by my method sixteen bobbins, as herein
shown, or any other number desired may be wound simultaneously on the one
spindle.
Various changes and modifications may be resorted to without departing from
the spirit and scope of my invention; I regard the simultaneous winding of a

page_text: plurality of bobbins on one spindle as new and broadly my invention, and also the
product resulting therefrom.
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. The method of winding bobbins, consisting in delivering to a winding spindle
a plurality of threads to be wound, and simultaneously winding said threads side
by side, building up successive contiguous bobbins thereby to constitute one threadi
mass, substantially as described.
2. The method of winding bobbins, consisting in spacing apart a plurality of
threads to constitute a plurality of bobbins, the successive thread or threads
for the respective bobbins being spaced apart distances corresponding to
the thicknesses of the resulting bobbins, and simultaneously winding said
threads to evenly build up the said plurality of bobbins progressively
side by side, whereby the contiguous ends sides thereof sustain
and guide each other, the whole being wound together in one thread mass,
substantially as described.
or
3. The herein described composite mass, comprising a plurality of complete
and distinct bobbins wound concentrically side by side and compacted together in
one coherent thread mass, substantially as described.
4. A composite thread package, comprising a central tubular foundation divided
into a plurality of ring-like portions throughout its length, and a corresponding
plurality of threads wound on said foundation and constituting a plurality of
distinct bobbins one for each of said ring-like portions, said plurality of bobbins
being compacted together concentrically with, said tubular foundation to form one
homogeneous thread mass, substantially as described.
5. A composite thread package, comprising a plurality of bobbins wound side
by side and integrally compacted together thereby, whereby they cling to each
other as one mass, said bobbins Being wound with different colors or kinds of
threads, substantially as described.
