Solicitors, at Frankfort-on-the-Main, in the Empire of Germany, for an
Invention of "IMPROVEMENTS IN REELS, SPOOLS, OR BOBBINS, AND IN THE

Frankfort on the Main, in the Empire of Germany. *" IMPROVEMENTS IN REELS,
SPOOLS, OR BOBBINS, AND IN THE METHOD OF MANUFACTURING THE SAME."
[A communication from Peter Adt, III, Peter Adt, junior, Johann Baptist Adt,
and Eduard Adt, trading under the Firm of Adt, Brothers, of Forbach (Germany),
Ensheim (Germany), and Pont-à-Mousson (France)].
This Invention relates to further improvements in the Invention described in
Letters Patent, dated 30th September, A.D. 1878, No. 3857.
According to the present Invention I manufacture spools or reels as follows, that
is to say :-
I make a spool for doubled yarn for doubling machines in which the plugs are
attached in the same manner as in single warp spools, the tube being folded over
the ends and plug, and in order to make the grooves without having to turn them
in the one piece the lower head is made of two discs, to which is given the necessary
form. When placed together the groove is between them.
In a sewing thread spool intended to be used in place of the ordinary flat card
spools, which cannot be used for sewing machines, I provide a hole in the centre
which enables them to be placed on a spindle.
I also provide what is known as a "Rabeth" spool, which I construct in the
following manner:-Tubes are first wound with an outer diameter and an inner
D

page_text: diameter, and cut off in lengths, the plug being either of paper or wood; if made of
paper it is constructed by placing several discs one upon another with suitable
binding material and pressing the same together. The tube and plug being finished
are placed upon a centre which is constructed in two parts. The whole is placed
in the winding machine shewn by Figure 18 in the Drawings of the aforesaid
former Patent, and in this machine receives a paper casing; thus a cylindrical tube
is produced provided with the tube and plug; it then receives an extra paper
wound around at the thick end, after which it is pressed into a shape having
somewhat rounded ends, one end being of somewhat greater diameter than the
other.
I make tubes for use in cotton spinning and wool spinning as follows, these
being designed to replace the wooden spools heretofore employed, that is to
say, I take plugs and rings which are then pressed upon tubes; the plugs and
rings are wound, cut to length, and pressed into shape before being placed on
the tubes.
It is a novel feature of my Invention that the spools may be made entirely
without wood, which is liable to be acted upon by the weather, and can never be
firmly joined to paper. If however wood plugs are used at all they would be as
herein described with reference to spools for doubling machines.

A communication from Peter Adt, III, Peter Adt, junior, Johann Baptist Adt,
and Eduard Adt, trading under the Firm of Adt, Brothers, of Forbach (Germany),
Ensheim (Germany), and Pont-à-Mousson (France).
This Invention relates to further improvements in the spools and other parts
described in the Specification of former Letters Patent, dated 30th September A.D.
1878, No. 3857.
According to the present Invention I manufacture reels, spools, or bobbins as
follows, that is to say:-
In the accompanying Drawing,
Figure I. represents an elevation and an end view of a sewing thread spool
intended to be used in place of the ordinary flat card spools, which cannot be used
upon a sewing machine. This spool is provided with a hole a in its centre, which
enables the said spool to be placed upon a spindle.
Figure II. represents in exterior view and partly in section a spool for doubled
yarn for doubling machines; the plugs in this spool are attached in the same manner
as in single warp spools. In order to provide the groover without having to turn
the lower head of the said spool the said lower head is formed of two discs b, b',
which are suitably shaped so that when placed together the groove is between
them.
Figures III. and IV. represent in exterior view and central section what is known
as a "Rabeth" spool, which I construct in the following manner, that is to say :-
A tube b is first wound with an outer diameter d', and an inner diameter d, and
then cut off into lengths as at l. The plug h is formed either of paper or wood; if
made of paper it is constructed by placing several layers one upon another with
suitable binding or adhesive material between them and pressing the same
together to the required form or shape. The said tube b and plug h when
finished are placed upon a centre, as shewn in section in Figure 5. This centre
is constructed in two parts n and m. The whole is then placed in the winding
machine, shewn by Figure 18 in the Drawings referred to in the Specification of
the aforesaid former Letters Patent, and in this machine receives or is encircled by
a paper casing a, thus a cylindrical tube is produced provided with the tube b
and plug h. This tube is then furnished at the end a¹ with an extra paper
wrapper, after which it is pressed into the shape illustrated in Figure 4 of the
Drawing.
Figures VI, VII., and VIII., represent in end view and partly
to be used in cotton spinning, and
in section, tubes
Figure IX. represents in similar views a form of spool for wool
being designed to replace the wooden spools heretofore employed,
the plug h and rings i are pressed into contact with the tubes a.
rings are wound, cut to length, and pressed into shape before being

page_text: Having thus fully described the said Invention and the manner of performing
the same, I wish it understood that I claim,―
First. The spool provided with the hole a, substantially as shewn in Figure I. of
the Drawing, and for the purpose specified.
Second. The manufacture of spools similar to the well known "Rabeth" spools,
substantially as above set forth.
Third. The construction of the paper spinning tubes, shewn in Figures VI. to IX.
of the Drawing, substantially as above set forth.
In witness whereof, I, the said Frank Wirth, have hereunto set my hand
and seal, this First day of November, in the year of our Lord One
thousand eight hundred and eighty-one.
