PROVISIONAL SPECIFICATION.
Improvements in or relating to Spool or Bobbin Supporting Devices
for use with Sewing Machines.
We, JOHN BUTCHER of Hollywood, Springfield Road, Leicester, Boot
Manufacturer and JOHN CLARKE of 72 Clarendon Park Road, Leicester
Machinist, do hereby declare the nature of this invention to be as follows:-
This invention has reference to an improved construction of spool or bobbin
supporting device for use with sewing machines and is designed with a view of
permitting the thread to feed freely and uninterruptedly to the needle of machine.
The present method of supporting the spools or bobbins in sewing machines
consists of a vertical spindle fixed at its lower end to the arm of the sewing machine
and over which the bobbin is placed in the well known manner.
This method of supporting the spools or bobbins is attended with considerable
disadvantages, as the thread in leaving the bobbins frequently gets underneath and
becomes wrapped round the lower part of the spindle causing an irregularity in
the tension of the thread for the time being & suddenly breaking the thread and
necessitating stoppage of the machine and loss of time.
The object of the present invention is to construct a spool or bobbin holding
device which will obviate these disadvantages. This invention consists of a frame
or bracket which may be fixed to a convenient part of a sewing machine or be
provided with a tube to fit over the present bobbin spindle.
The bobbin may be attached to the frame by a removable spindle which passes
through the upper end of the frame or bracket and partly through the barrel of
the bobbin while the latter rests on the lower part of the said frame or bracket
in such a manner that when the thread gets underneath it can get away to
the needle there being no spindle or projection underneath the said bobbin to
prevent it so doing.

COMPLETE SPECIFICATION.
Improvements in or relating to Spool or Bobbin Supporting Devices
for use with Sewing Machines.
We, JOHN BUTCHER of Hollywood, Springfield Road, Leicester, Boot
Manufacturer, and JOHN CLARKE of 72 Clarendon Park Road, Leicester,
Machinist, 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 has reference to an improved construction of spool or bobbin
supporting device for use with sewing machines, designed with a view of permitting
the thread to feed freely and uninterruptedly to the needle of the machine.
The general method of supporting the spools or bobbius in sewing machines
consists of a vertical spindle fixed at its lower end to the arm of the sewing machine
and over this spindle the bobbin is placed in the well known manner.
This method of supporting the spools or bobbins is attended with considerable
disadvantages, as the thread in leaving the bobbins frequently gets underneath the
latter and becomes wrapped or coiled round the lower part of the spindle thereby
causing an irregularity in the tension of the thread for the time being and

page_text: suddenly breaking the thread and necessitating stoppage of the machine and
loss of time.
The object of the present invention is to construct a spool or bobbin holding
device which will obviate these disadvantages. This invention consists of a frame
or bracket which may be fixed to a convenient part of a sewing machine or the
said bracket may be provided with a tube to fit over the bobbin spindle belonging
to the machine.
A removable spindle passes through or into the upper end of the frame or bracket
and partly through the barrel of the bobbin while the latter rests on the lower
part of the said frame or bracket in such a manner that when the thread gets
underneath, it can get away to the needle there being no spindle or projection
underneath the said bobbin to prevent it so doing.
Referring to the accompanying drawing,
Figure is a perspective view of a spool or bobbin supporting device
constructed according to this invention.
Figure 2 is a similar view of a modification thereof.
A is the framework which may be formed integrally with the arm or other
convenient portion of a sewing machine, or connected to the usual bobbin spindle
of the latter by a tube or sleeve A¹ passed thereover and fastened in position by a
screw A.
In the upper horizontal arm C of the bracket there may be a tube A³ or
equivalent through which passes a vertical spindle B the latter being of such a
length as not to reach the base-plate A of the bracket but constructed so as to
leave a space of say of an inch or thereabouts between the same.
To place the spool or bobbin in working position the spindle is raised and the
former placed upon the base-plate of the bracket.
The said spindle is then lowered into the barrel of the bobbin so as to keep the
latter resting on the base-plate.
By arranging the length of the spindle so that it does not reach the base-plate
upon which the bobbin rests any coils of thread leaving the latter and getting
underneath the same are free to pass to the needle as there is no spindle or upward
projection on the base-plate for the said thread to coil round.
In the modification shown in Figure 2 the spindle B is bent at its upper end and
is passed into a tubular socket C₁ so as to be movable laterally in one direction to
admit of the bobbin being placed thereon and removed therefrom.
A projecting portion C³ of the horizontal arm C prevents the spindle moving in
the opposite direction.
It is obvious that the spindle might be fixed and non-removable, in which case
the base-plate would be provided with a hinge so as to permit of moving up and
down in relation thereto and thus allow of the bobbin or spool being placed in
position.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a spool holder for sewing machines the combination of a vertically depending
spindle that does not reach to the spool supporting plate substantially as and for
the purpose described.
2. The improved construction of spool or bobbin holder substantially as described
and illustrated in the accompanying drawing.
