Improvements in Buttons.
I, EUGEN TURCK, Manufacturer, of Liebigstrasse, No. 11, Lüdenscheid, in the
German Empire, do hereby declare the nature of my invention to be as follows:-
This invention relates to clothes buttons composed of several parts, as represented
by the accompanying drawings Figs. 1 to 10.
The lower part or base plate is made of a specially shaped sheet metal disc,
represented by Fig. 1. The circumference of this disc, instead of forming a com-
plete circle, has a suitable number of equi-distant projections e fb, e¹, f......³, f
each of which is bounded by a short curve, and the said curves are of such a size
and shape, that they form together a complete circle, having approximately the
diameter of the shank or pin D of the button. In the example shown by Fig. 1
there are six radial projections; consequently each of the said short curves, ef³,
ef.... forms one sixth of a circle, and its length is approximately D.
thus
until
The metal disc shaped as described, is now provided with cuts extending from the
base of the said projections towards the centre at a slight angle to the radius, as
indicated in Fig. 1 by dotted lines, and the segments e¹ƒ c² d, e² f1 c² (!,
produced are turned inward around their respective bases c¹ d, c² d', c³ d²
their curved ends meet and form a circular opening of the diameter D. This
operation produces at the same time 6 intermediate segments a bed, a² b' c² d',
which may likewise be bent or turned on their respective bases cd, c' d', c² d².
When the strips ef³, f...
.... are bent up, the base plate assumes the shape
represented by Fig. 8. If now the intermediate segments a b c d, a' b₁ c'd',.
are bent down in the direction of the arrows in Fig. 8, the diameter of the base
plate (which is equal to that of the mouth of the upper disc or plate) is enlarged,
and becomes equal to the diameter of the circular groove formed in the upper
plate (Fig. 2). In this manner the base plate may be united with the upper or
cover plate, in case the latter consists of rigid material, such as vegetable ivory,
horn, mother-of-pearl. If the upper disc is flexible, its edge may be turned down
over the edge of the base plate, as represented by Fig. 5.
As shown by Figs. 1 and 8, the base plate has a central opening, to receive the
shank D of the button, and to form a guide or bearing for the same.

The bearing, instead of being simply stamped out of the plate, may be a
cylindrical flange bent up from the centre, as shown by Fig. 5, and serving as a
support to the extremities elf, e² ƒ³, e³ fa. of the radial strips shown in Fig. 1.
In this case, the said strips e¹f c¹ d, e³ f¹ c² d¹ can only be bent up until their
extremities rest on the edge of the said bearing and find a support on the same.
Instead of making the said supporting ring S cylindrical, as in Fig. 5, it may be
nade conoidal, as represented by Figs. 6, 7, 9 and 10, but in this case it serves no
longer as a lateral guide to the shank or central pin. To provide such a guide,
I employ a second base plate, from which a hole is stamped out in the centre; this
supplemental base plate may be secured to the first base plate, as shown by B',
Fig. 7, or it may be connected with the upper plate, so as to form a cavity con-
taining the first plate, in the manner represented by Figs. 6, 9 and 10.
Fig. 4 shows such a supplemental base plate B provided at its circumference with
recesses or cuts, which enable the edge of the said base plate to be introduced into
the circular groove of an upper disc A made of vegetable ivory or other rigid
material. The said cuts or recesses produce segments, which are bent up around
D

introduced into the groove of the upper plate.

Improvements in Buttons.
I, EUGEN TURCK, Manufacturer, of Liebigstrasse, No. 11, Lüdenscheid, in the
German Empire, 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 clothes buttons composed of several parts, as represented
by the accompanying drawings Figs. 1 to 12.
The lower part or base plate is made of a specially shaped sheet metal disc,
represented by Fig. 1. The circumference of this disc, instead of forming a
complete circle, has a suitable number of equidistant projections e¹ƒ—² ƒ—³ ƒ^
each of which is bounded by a short curve, and the said curves arc of such a size
and shape, that they form together a complete or almost complete circle having
approximately the diameter 8 of the shank or pin of the button. In the example
shown by Fig. 1, there are six radial projections, consequently each of the said
short curves forms one sixth of a circle, and its length is approximately
δπ
The metal-disc shaped as described, is now provided with cuts extending from
the base of the said projections towards the centre, as indicated in Fig. I by dotted
lines, and the segments e fel de²ƒ³ c² d²-e³ 12 c³ ³... thus produced are turned
inward around their respective bases c¹ d, c² d', e³ d² etc. as indicated in Fig. 3 by
dotted arcs, until their curved ends meet, or are close together and form a circular
opening of the diameter §.
The connection with the shank and counter plate of the button, represented by
Fig. 12, may now be made by pushing the head of the shank through the central
opening Fig. 3, thereby pressing apart the segments e¹f, e³, .... When the
head of the shank has passed through the opening, the segments will snap back
again, owing to their elasticity.
The head of the shank may be pointed, as in Fig. 12, in order to pierce the
cloth, on which the button is to be fastened.
In the centre of the base plate a supporting ring, of cylindrical or conoidal shape
(Fig. 3) is formed by bending up the inner edge of the same, in such a manner,
that it supports the segments close to their curved extremities e¹ f, ef¹, e³ f2.
Consequently, when the shank is being drawn up or tightened, the segments efcd,
2 f¹ c² d¹, e³f c³ d², cannot continue to turn on their bases c¹ d, c² d', c³ d², ..
because they rest on the edge of the supporting ring.
The six intermediate segments a b c d, a' b c d', etc. remain at disposal, and may
be utilized in various ways.
The bases of each pair of segments depend upon each other as regards their
length, so that by widening the base of one segment, that of the adjoining segment
will be narrowed by the same amount.
For instance, in Fig. 3 the bases of the segments e¹ fc² d, e² f¹ c² d', eª³ƒª c³ d² etc.
are narrow, while the bases of the segments a b c d, a' b c d¹
are wide.
In Fig. 5 the segments a b c d, a¹ b¹ c¹ d-have shorter bases, and the
segments efc¹ d, e² ƒ¹ c² d' . . . have wider bases.
Figs. 10, 9, 7, 11, 8 and 6 show various methods or means of connecting the
segments a bed, a¹ b¹ c¹ d¹. . . with the upper plate or button top, or with a second
base plate.

page_text: In Fig. 10, a solid connection is produced by bending the edge of the upper
plate around the extremities of the segments, or by holding the latter in a groove
of the flanged upper plate. In Fig. 9 a second bottom plate is used, which has in
the centre a perforation serving to guide the shank of the button. The edge of
the second bottom plate is bent over the edges of the segments.
In Fig. 7 the edge of the top plate is bent down over the edges of the segments
and of a second bottom plate.
In Fig. 11, the edge of a second bottom plate is bent over the edges of the
segment and also over the edge of a cover plate, in a manner similar to Fig. 9.
Fig. 8 represents a clothes button composed of a first bottom plate, as shown by
Fig. 3, a cover plate, as shown by Fig. 2, and a second bottom plate of the kind
shown by Fig. 4. This second bottom plate has radial cuts at the circumference,
which divide it into 12 (or any other suitable number of) segments, a¹ b¹ c¹d',
a²² d², etc. which are turned on their bases c d, eď, «²ď².
turning these segments in the manner indicated in Fig. 4 by dotted lines, the
diameter of the disc is increased from / to the diameter of the circular groove of
the upper plate or disc shown in Fig. 2.
By thus
In this case the segments abc d, a' b¹ c¹ d'... of the first bottom plate are
placed between the top plate and the first bottom plate.
Fig. 6 represents a clothes button composed of an upper plate, as in Fig. 2 and a
lower plate as in Fig. 3. In this case the segments a bed, a b c d' of Fig. 3
are bent on their respective base lines cd, c'd¹.... sufficiently, for introducing
them into the groove of the upper plate Fig. 2, as has been described with reference
to Fig. 4 for the case of a second bottom plate. The supporting ring is cylindrical
and serves as a guide or bearing for the button shank.
With the exception of the variety shown by Fig. 9, care must be taken, to leave
sufficient clearance, that the head of the button shank requires but slight pressure
to pass through the opening formed between the ends of the segments efe¹ d,
ed, when the latter have been turned on their respective base lines until
their ends touch the top plate.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
--
1. A clothes button having a bottom plate divided into pairs of segments by
cuts extending from the circumference, one set of segments being then turned
inward on their respective base lines, so as to form a circular opening for the
shank, while the other segments are either held in the turned down flange of
an upper plate, as represented by Fig. 10, or introduced into a circular groove
turned into the upper plate, as represented by Fig. 6, and the centre or uncut,
portion of the bottom plate being raised, so as to form a cylindrical ring adapted
to support the segments immediately behind their curved ends c¹ƒ, c² ƒ'
to serve as a guide and bearing for the shank of the button.
and
2. A clothes button having two bottom plates, one of which is formed in the
manner described above but provided with a conoidal supporting ring, and with
segments a b c d, a¹ b¹ c¹ d¹... held in the bent down edge or flange of the second
bottom plate, which has in the centre a perforation adapted to serve as a bearing
for the button shank, as represented by Fig. 9.
3. A clothes button comprising two bottom plates of the kind specified above,
and a top plate the edges of which are bent down over those of the bottom
plates, as represented by Fig. 7.
4. A clothes button comprising two bottom plates of the kind specified above,
and a top plate, which together with the first bottom plate is held in the bent
down edge or flange of the second bottom plate. as represented by Fig. 11.
5. A clothes button comprising a top plate with turned groove and two bottom
plates, the first bottom plate having segments a b c d , a¹ b' c² d'….
which are
introduced into the grooved top plate through the clear opening 1, Fig. 2, while

page_text: the second bottom plate is divided by cuts from the circumference into segments,
which are turned on their respective bases so as to increase the diameter of the
said second, bottom plate and to effect the introduction into the groove of the
top plate, as represented by Fig. 8.
6. A clothes button comprising a top plate provided with a turned-groove, and a
bottom. plate of the kind' represented by Fig. 3, the segments a bed, a¹¢¹d.
of the latter being turned on their respective base lines c d; c' d¹. . . . and thereby
introduced into the groove of the top plate, as represented by Fig. 6.
