Improvements in or relating to Devices for Attaching Shanks to
Buttons.
I, EMIL TELTSCHIK, of 37 Berggasse, Vienna, in the Empire of Austria-
Hungary, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a device for fixing buttons of all kinds, which
device can be cheaply and readily applied to the button and which enables the
button to be easily and firmly sewn on to the fabric and is moreover of great
durability.
The invention thus comprises a shank to be fixed in a particular manner to
the body of the button, by the aid of which shauk the button can be sewn on to
tbe fabric, and further a menus for attaching such shank to the body of the
button.
The fixing device consists of a special form of shank of wire or sheet metal
fixed to the button, this shank being made in such a manner that the arms, starting
from the centre piece of. a flat star of flexible metal, having three four or more
rays are turned up vertically while a short piece of their extremities is bent
outwards. Thereupon this shank with its bent up free extremities of the rays or
arms is inserted into a cavity provided at the bottom of the button, the exterior
edge of which is cut out downwardly, then a ring of U shaped cross section is slid
upon this shank, so that the hollow side of the ring is directed toward the button,
and subsequently the ring is driven in by means of a press, so that the exterior
edge of said ring grips underneath the exterior edge of the button which is cut
out below, whilst its interior edge rests upon the bent extremities. of the arms.
The shank is thus connected to the button in the most simple manner. Any
accidental compression, which might cause the shank to easily drop out, is
prevented in such a manner, that in the centre of the cavity of the button a small
projection is provided which enters between the extremities of the arms On
Bewing the button to the fabric the thread is drawn through the intervals between
the arms of the star which arms freely project from the button, and the bottom of
the star.
In another device for fastening the shank to the button, which is especially
suitable for fabric- or cloth buttons, the free extremities of the arms, which may,
if required, be bent outwards at their outer extremities, are pressed between the
sheet metal portion forming the back of the button and between the edge of a
sheet metal cap placed upon the rear of the button core or body, the said edge may
or may not be bent upward, and the aforesaid free extremities of the arms are held
fast in such a manner that the sheet metal cap entering between the arms prevents
these arms from being accidentally pressed together. Instead of the cap a flat disc
may also be used. In this case the shank is held fast in such a manner that the
inwardly bordered interior edge of the sheet metal back grips beneath the
extremities of the arms, which extremities are in this case bent outwards and
downwards.
In a further constructional form of this fastening device the only difference
between that just described is that inside the button core or body a groove is
provided, into which enter the bent extremities of the arms and are held fast by
the overlapping sheet metal cover, whilst the interior edge of the groove.prevents
the arms from being accidentally pressed together.

page_text: If, the star is made of sheet metal, the danger may occur of the thread being
cut off by contact with the sharp edges of the arms and the bottom of the star, and
in order to meet this disadvantage small tongues starting from the centre piece are
stamped out between the rays or arms of the star,' which tongues are bent upwards
and inwards. Sometimes these bent up tongues are covered up inside by a sinall
star which is placed above upon the bent extremities of the tongues, whereupon
the arms of this small star are turned down and inwards.
The shanks may also be suitably made of wire, such shank may be produced in
such a manner that an even or flat star is made of wire, the arms or rays of which
consist of wire pieces arranged parallel in pairs side by side which wire pieces are
connected at the outer extremities, whilst the adjacent wire pieces of adjacent rays
pass over into each other by a rounding, the centre of the star being empty. If
then the arms of this star are turned up vertically, so that the adjacent wires of
adjacent arms together with the roundings forming the transition between the said
arms will form the lateral surfaces of a prism, the a shank consisting of several
parts is obtained which only differs from the shauk first herein described by the
fact, that it has no bottom, so that the thread during the sewing operation is
drawn over the rounding.
The outer extremities of the arms are in this case likewise bent outwards.
These outer extremities may also be so formed that the outer extremities of the
wires forming one arm of the star are made to pass over into each other by a
semi-annular curve.
The shank, as is apparent, consists in every case of a number of arms, parallel to
each other and vertical to the button-surface, these arms being on the one hand
fixed inside the button and on the other hand connected to each other by the
bottom of the star shank or by stays; the said shank being in all cases sewn on
in such a manner that the thread is passed through the intermediate spaces between
the arms and the bottom or stays respectively.

Improvements in or relating to Devices for Attaching Shanks to
Buttons.
I, EMIL TELTSCHIK, of 37 Berggasse, Vienna, in the Empire of Austria-
Hungary, Manufacturer, 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 a device for fixing buttons of all kinds, which
device can be cheaply and readily applied to the button and which enables the
latter to be easily and firmly sewn on to the fabric and is moreover of great
durability.
The invention thus comprises a shank to be fixed in a particular manner to
the body of the button, by the aid of which shank the button can be sewn on
to the fabric, and further a means for attaching such shank to the body of the
button.
In the accompanying drawing;
Figure 1 is a plan view and a side view respectively of a blank for producing
the shank.
Figure 2 is a plan view and a side view respectively of a shank made from the
blank shown in Figure 1.

page_text: of the button.
Figures 34, 38, 30, 3D and 3 show modified devices for fixing the shank to the
body of the button, likewise in vertical section.
Figure 4 shows a plan of a sheet metal covering piece.
Figure 5 illustrates in vertical section the method of applying the same to the
shank.
Figure 6 shows a plan and side view respectively of a blank made of wire and
serving to produce a somewhat modified shank.
Figure 7 represents in plan and side view respectively, the shank as produced
from the blank shown in Figure 6.
Figure 8 shows a plan and side view respectively of a blank likewise made of
wire and serving to produce another slightly modified shank and
Figure 9 shows a side view and plan of a shank made out of a blank as
represented in Figure 8.
The fixing device consists of a special form of shank of wire or sheet metal fixed
to the button, this shank being made in such a manner that the arms A, starting
from the centre piece D of a flat star of flexible metal, having three, four or more
arms (Figure 1), are turned up vertically while a short piece of their extremities
is bent outwards (Figure. 2). Thereupon this shank with its bent up free
extremities a of the arms A is inserted into a cavity B provided at the bottom of
the button (Figure 3), the exterior edge 6 of which is cut out downwardly, then a
ring C of U shaped cross section is slid upon this shank, so that the hollow side of
the ring is directed toward the button, as is illustrated in dotted lines in Figure 3,
and subsequently the ring C is driven in by means of a press, so that the exterior
edge of said ring grips underneath the edge b which is cut out below, whilst its
interior edge rests upon the bent extremities a of the arms A. The shank is thus
connected to the button in the most simple manner. Any accidental compression,
which might cause the shank to easily drop out, is prevented in such a manner,
that in the centre of the cavity B of the button a projection is provided which
enters between the extremities of the arms A, as shown in Figure 3. On sewing
the button to the fabric the thread is drawn through the intervals between the.
arms A of the star which arms freely project from the button, and the bottom D
of the star.
Figure 3 shows another device for fastening the shank to the button, which is
especially suitable for fabric- or cloth buttons. The free extremities of the
arms A, which may, if required, be bent outwards at their outer extremities (at a),
are in this device pressed between the sheet metal portion B forming the back of
the button and between the edge of a sheet metal cap placed upon the rear
of the button core or body E, the said edge & may or may not be bent upward, and
the aforesaid free extremities of the arms A are held fast in such a manner that the
sheet metal cap entering between the arms A prevents these arms from being
accidentally pressed together. Instead of the cap a flat disc 6x, (Figure 3) may
also be used. In this case the shank A is held fast in such a manner that the
inwardly bordered interior edge of the sheet metal back B₁ grips beneath the
extremities a of the arms A, which extremities are in this case bent outwards and
downwards.
Figure 3B shows another constructional form of this fastening device which only
differs from that illustrated in Figures 34 and 3 by the fact that inside the button
core or body E a groove e is provided, into which enter the bent extremities a of
the arms A and are held fast by the overlapping sheet metal cover B', whilst the
interior edge of the groove e prevents the arms A from being accidentally pressed
together.
The mode of fastening the shank shown in Figure 3 may also be applied to
fabric or cloth buttons as shown in Figure 3D.
A sheet metal back B1 is secured
to the button core E this sheet metal back B' having a central recess with an
undercut edge b and a projection bin its centre which enters between the arms of

page_text: the shank. The shank is inserted into this recess and is held in place by a ring C
pressed down upon the button back so that ite inner edge bears upon the outwardly
bent extremities of the arms of the shank while its outer edge enters under the
undercut edge b of the recess in the sheet metal back.
Another modification of the mode of fastening the shank to the button illustrated
by Figure 34 which is also applicable to fabric or cloth buttons is shown in
Figure 3. The cap placed on the button ere E is held in position by the
inner face of an inwardly projecting rib in the sheet metal back B' while the
inwardly bent inner edge of the central hole of the sheet metal back clamps
the outwardly bent extremities of the shank arms A between itself and the
cap
In the modification shown in Figure 3 a sheet metal back B' having a hole in
its centre and an inwardly projecting annular rib & concentric with such hole is
secured to the button body; a sheet metal cap is placed between the button
body and the metal back B and is held in position by its outer edge abutting
against the inwardly projecting rib of the back B' while the raised central portion
of the cap projects through the central hole in the back B'. The outwardly hent
ends a of the shank are beld between the inwardly bent edge of the central hole in
the back B and the cap 6 the projecting central portion of the latter entering
between the arms of the shank as described with reference to Figure 3^.
If, as shown in Figures 1 and 2, the star is made of sheet metal, the danger may
occur of the thread being cut off by contact with the sharp edges of the arms A
and the bottom D, and in order to meet this disadvantage small tongues a starting
from the centre piece D are stamped out between the rays or arms A of the star,
as is illustrated at the left hand side of Figures 1 and 2, which tongnes are bent
upwards and inwards as is shown upon the right hand side of Figures 1 and 2.
Sometimes these bent up tongues a are covered up inside by a small star a
Figure 4, which is placed above upon the bent extremities of the tongues a',
whereupon the arms of this small star a are turned down and inwards, as shown in
Figure 5.
The shanks may also be suitably made of wire, such shank may be produced in
such a manner, that an even or flat star is made of wire (Figure 6), the arms or
rays A of which consist of wire pieces arranged parallel in pairs side by side, which
wire pieces are connected-arine outer extremities, whilst the adjacent wire pieces
of adjacent rays pass over into each other by a rounding a*, the centre of the star
being empty. If then the arms of this star are turned up vertically, as shown
in Figure 7, so that the adjacent wires of adjacent arms together with the
roundings a forming the transition between the said arms will forn the lateral
surfaces of a prism, then a shank consisting of several parts is obtained which only
differs from that shank, illustrated in Figures 2 and 3, by the fact, that it has
no bottom, so that the thread during the sewing operation is drawn over the
rounding a*.
The outer extremities of the arms A¹ are in this case likewise bent outwards as
shown at a in Figure 7. These outer extremities may as shown in Figures 8.
and 9, also be so formed that the outer extremities of the wires forming one
arm of the star are made to pass over into each other by a semi-annular curve a.
The shank, as is apparent, consists in every case of a number of arms A or A',
parallel to each other and vertical to the button-surface, these arms being on the
one hand fixed inside the button and on the other hand connected to each other by
the bottom D or by stays a*; the said shank being in all cases sewn on in such a
manner that the thread is passed through the intermediate spaces between the
arms A and the bottom D or stays a* respectively.
