Improvements in Tensioning or Holding Devices and Cutters for use
with Spools or Coils of Thread, Rope, or the like.
I, CHARLES FREDERICK FOGG, of 108, Fulton Street, New York City, New York,
United States of America, Mechanic, 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 especially to devices employed for maintaining a proper
tension upon a spool or coil of thread, rope, or any equivalent material when coiled
upon a base, and has for its object the provision of a simple, cheap, and effective
device which is easy to apply, and effective in operation.
To attain the desired end, my invention consists essentially in strap of spring
metal, bent into circular form, one extremity of said strap being perforated for
the passage of the confined material there-through, and the other extremity pro-
vided with a slit or cut for convenience in severing the material from the body,
all of which will be hereinafter first fully described and then pointed out in the
claims.
In the accompanying drawing, forming a part hereof, Fig. 1 is a plan view of
my tension and cutter, before it is bent into circular shape. Fig. 2 shows the same
as bent to shape, and in place upon a spool of thread. Fig. 3 is a cross sectional
view at linear of Fig. 2.
Like numerals of reference, wherever they occur, indicate corresponding parts
in all the figures.
At 2 it is perforated
The strap or strip
1 is a strap of spring metal, hard brass or steel, as preferred.
and at 3 it is notched or cut from the edge toward the centre.
of metal is bent to a circular shape, when it is ready for use.
In applying my improved tension and cutter to a spool of thread, the end, 4
of the thread is passed through the perforation 2, and the device sprung over the
body of the thread. When it is desired to remove a length of thread, it is drawn
off in the usual manner, the band of metal remaining stationary while the spool
revolves, and when a sufficient quantity of the thread has been removed, by passing
the end 4 into the notch 3, the band is locked against revolving, and a slight
pull will sever the thread at that point leaving an end 4 still projecting from the
perforation 2, effectually preventing the unwinding of the thread. As the thread
is drawn off the spool, the band travels longitudinally thereon, the spool revolving
therein, and the band is always automatically located in the proper position,
without the exercise of any care or attention.
The device may be used as a tension only, without employing the cutting notch,
and when so used on a sewing machine, keeps the thread at all times in place
upon the spool. It is obvious that the tension device may be applied to any coil
of material it is desired to keep from unwinding from the body more rapidly than
required.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. A tension device consisting of a strap of spring material, bent in the form
of a circle, and having one of its extremities perforated, substantially as and
for the uses and purposes shown and described.
2. A tension device consisting of a strap of spring material, bent in the form of
a circle, and having one of its extremities perforated, and the other notched,
substantially as and for the uses and purposes shown and described.
3. The combination with a spool of thread, of a spring material, circular strap,
passing around the thread one extremity of the strap being perforated, and the
other cut or notched substantially as shown and described.
