"IMPROVEMENTS IN REELS FOR THREAD AND IN THE METHOD OF MANUFACTURING
THE SAME A communication from abroad by Anatole Descamps, of Lille in
the Republic of France.
This invention relates to an improved reel for carrying thread or the like such
as used for sewing, embroidery and so forth and to a method of manufacturing
the same.
The reels heretofore used for this purpose are generally made of wood and,
comparatively speaking, heavy, but means have been wanting to produce the same
in a cheap and expeditious manner from cardboard thin sheet metal and the like,
which on account of their lightness would be preferable
By means of ordinary stamping machines aud a suitable die, a disc of any of
the materials above indicated is made. This disc is circular in outline and its
centre is depressed or dished so as to form the whole into a more or less shallow
cylinder with a flange on one side the shape being very similar to that of a hat;
in the depressed part (and preferably simultaneously with the dishing) one or
more small holes are made. Care is taken to have the bottom of the depression as

page_text: nearly flat and the sides of the cylinder as nearly parallel to each other and the
angles rectangles and as sharp as practicable.
The reel is formed by attaching the small end of one of these "hats" to the
small end of another and this is easily effected by passing eyelets through the
holes in the depressed parts and stamping the eyelets up as is done for labels
boots and numerous other articles by means of an ordinary eyeletting machine.
The block of the eyeletting machine may however with advantage be made of
such shape and size as to closely fit within the dished discs as this will facilitate
the work and and keeps the cylindrical parts in line. The reel is thus formed the
two rims of the "hats forming the flanges or ends of the reel. The size and
strength of these reels can of course be varied.

"IMPROVEMENTS
IN REELS FOR THREAD AND THE LIKE, AND IN THE METHOD OF MANUFACTURING
THE SAME." A communication from abroad by Anatole Descamps, of Lille in
the republic of France.
Bobbins or reels for supporting thread have hitherto been chiefly made of wood,
cardboard which by reason of its small weight is more advantageous, not being
applied to the manufacture of reels because of the difficulties met with in joining
the various parts; the same holds good as regards thin sheet metal.
This difficulty is solved by the following process. By one of the cardboard or
metal stamping machines commonly used in the trades and by means of a matrix
of suitable shape a circular disc of cardboard or metal is made in the shape of
a hat that is to say it has a dished centre with a flat bottom and edges, the
angles being as nearly rectangles as the flexibility of the cardboard or or of the
metal allows.
Fig G shows in elevation the shape which may be given to the stamp. At the
centre is a punch G' which whilst the stamp imparts the required shape to the
material pierces the bottom of the hat with a hole. This hole is of the same
diameter as a small metal eyelet B hereinafter mentioned
Fig A shows the section of a "hat "
Fig C shows the same "hat" in plan.
When this work has been done two hats are placed together back to back with
the holes in the centre in one line and an ordinary eyelet B such as is used in
the trades for eyeletting corsets and boots is introduced into the centre holes;
this part of the work is done by hand.
The eyelet is then crushed by the machine commonly used for this purpose care
being taken to make the bolster or support which takes the pressure represented
in Fig H of the same shape and size as the interior of the hat above described;
this will cause the reel naturally to be in the proper centre line of the closing
machine and the centre of the eyelet will exactly correspond with the cone which
serves to depress its edges.
The two hats shown in section in Fig D are thus closely united and form a
nearly cylindrical central body which carries the thread, and two edges which
prevent the layers of thread from slipping off.
Fig E shows the completed reel in perspective.
Fig F shows in perspective the reel with thread wound upon it in this case
diagonally The reel may be made of any size that may be required for this
purpose it will be sufficient to make the rigidity of the cardboard or metal pro-
portionate to the size of the object and to increase the number of points where
the jointing is effected by providing a greater number of holes and eyelets.
Other kinds of rivets can of course be substituted for the eyelets if desired
but the eyelets are preferable for many reasons.
The width between the edges, and consequently the thickness of the bobbin are
likewise variable, and may be increased or diminished as required.
Having now described this invention as communicated to me by my foreign

page_text: correspondent I wish it to be understood that what claim and desire to protect
under the herein before in part recited Letters Patent is ;
First The manufacture and use of reels or bobbins consisting of two hats or
dishes (A) of cardboard or metal united at their central parts by means of
one or more eyelets or their equivalent substantially in the manner described
and illustrated.
Second As a portion of a reel, or bobbin, the hat or dish A substantially as
described and illustrated.

and seal this tenth day of November in the year of Our Lord One
