COMPLETE SPECIFICATION.
Improvements in Spool Attachments for Sewing Machines.
I, HELEN LOUISA WEBSTER, residing at Church Street, in the City of
Wellesley, in the County of Norfolk, and State of Massachusetts, United States
of America, Educator, 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 :-
This invention relates to spool supports for sewing machines, and the object
thereof is to provide an improved device of this class which is designed to prevent
the thread from wrapping around the support of the spool and being broken.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which ;-
Fig. 1, is a side view of my improved spool support;
Fig. 2, a central vertical section thereof;
Fig. 3, a central vertical section of a modified form of construction; and,
Fig. 4, a similar view of another modification.
In the drawing forming part of this specification, reference being made to
Figs. 1, and 2, I have shown at 5 the usual pin which is connectel with the arm
of all sewing machines, by means of a screw threaded shank 6, or other suitable.
device, and said pin is provided with a circular disk or plate 7, on which the spool
ordinarily rests; and in the practice of my invention, I provide a supplemental
support which consists of a conical tubular portion 8, which is mounted on the pin 5,
and which is provided with a circular base 9, the diameter of which is equal to or
greater than the diameter of the end of the spool.
I have also shown in Figs. 1, and 2, a spool 10, which is mounted on the
supplemental support 8, and in practice, 1 provide an auxiliary holder 11, which
is also conical in form and provided with a circular head 12, and the auxiliary
holder 11, is provided with a central bore 13, and is inserted into the upper end
of the spool, the pin 5, passing therethrough.
It will thus be seen that the spool when in position does not come in contact
with the pin, but rests upon the conical support 8, and is centered on said pin 5,
by the auxiliary holder 11. The holder 11, and the support 8, revolve on the
pin 5, with the spool, and if at any time the thread should become unwound, so as
to slip off the spool below or above it, it will be wound either on the conical
support between the lower end of the spool and the base 9, of said support, or
on the auxiliary holder 11, between the upper end of the spool and the circular
head 12, both of which revolve as herein before described, and there will therefore
be no danger of breaking the thread.
In spool holders or supports for sewing machines as usually constructed, the
thread when it becomes detached from the spool, will be wound on the pin 5, and
since this is stationary, the thread is sometimes broken, as is well known by all
those familiar with this class of devices, and the object of my improvement is to
prevent this breaking of the thread, and my improved support is perfectly adapted
to accomplish this result.
The diameter of the conical support 8, or the lower portion thereof, is greater
than that of the bore of the spool, the difference between the diameters of the top
and bottom of the cone being from one-eighth to one-quarter of an inch, and thus

page_text: the device accommodates itself to spools of different sizes, and this is also true of
the auxiliary holder 11.
In Fig. 3, I have shown a modified form of construction, in which I employ a
central tube 14, on the lower end of which is secured a spool shaped support or
holder 15, which is rigidly secured thereto, and in practice, the pin 5, is inserted
through the tube. 14, and the spool is mounted on the upper end of said tube, and
revolves therewith.
The spool in this case rests on the upper circular head 16, of the spool shaped
support 15, and the lower circular head 17, of said support rests on the circular
disk or plate 7, secured to the pin 5. Au auxiliary holder exactly corresponding
to this is placed upon the upper end of the spool.
In Fig. 1, I have shown another modification in which I employ a central tube 14,
the base of which is provided with a conical, tubular support 18, having a circular
base 19, which rests in practice, on the disk or plate 7, shown in Figs. 1, and 2,
and the spool in practice, is mounted on the tube 14, and rests on the circular
portion; in this form of construction, the tube 14, projects upwardly through the
spool and is provided with the auxiliary bolder 11, which is the same as the
bolder 11, shown in Figs. 1, and 2, and which is fastened to the upper end of
the tube and this form of support operates in the same manner as those represented
iu said Figs. 1, and 2..
In practice, I prefer the construction shown in Figs. 1, and 2, but the
construction shown in Figs. 3 and 4, may be employed whenever necessary
or desirable, and that shown in Fig. 4, is particularly applicable to certain
classes of machines.
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;
1. In a spool support for sewing machines, the combination with a pin as 5,
which is adapted to be secured to the machine, of a conical tubular support as 8,
provided with a circular base as 9, and an auxiliary conical tubular holder as 11,
provided with a circular head as 12, said parts being adapted to operate, substan-
tially as shown and described.
2. A spool support for sewing machines, consisting of a pin rigidly secured to
the machine, and a conical support mounted thereon, and adapted to revolve
thereon; said support being provided at its lower end with a circular base which
is equal to or greater in diameter than the end of the spool, substantially as shown
and described.
3. A spool support for sewing machines, consisting of a pin rigidly secured to
the machine, and a conical support mounted thereon, and adapted to revolve
thereon, said support being provided at its lower eud with a circular base which
is equal to or greater in diameter than the end of the spool, and an auxiliary
holder which is adapted to be mounted on said pin at the upper end thereof,
and adapted to revolve thereon, said auxiliary holder being conical in form, and
adapted to be inserted into the upper end of the spool, and having a circular
head equal to or greater in diameter than the end of the spool, substantially as
shown and described.
4. A spool support for sewing machines which is adapted to be mounted on
the usual pin connected therewith, said support consisting of a conical tubular
portion, which is provided with a circular base, the diameter of which is equal
to or greater than that of the end of the spool, substantially as shown and
described.
5. The herein described device for supporting spool of thread on sewing
machines, which consists of a tubular device adapted to be mounted on the pin
with which the machines are provided, said device being adapted to revolve on
said pin, and being also adapted to support a spool, and being provided with a

page_text: conical tubular portion having a circular base, the diameter of which is
equal to or greater than that of the end of the spool, substantially as shown.
and described.
