PROVISIONAL SPECIFICATION.
Improvements in Detachable Buttons or Studs.
I, JOHANN HINRICH SOHNHOLTZ, of 9 Bachstrasse, Hamburg, in the Empire
of Germany, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My present invention relates to detachable buttons or studs in which the
fastening is effected by means of a folding wing pivoted to the shank of the button
and especially that class of such buttons, in which the length of the shank is a
variable one. The object of this improvement is to afford means for automatically
arresting the longitudinally movable parts of the shank in order to facilitate the
shifting of the folding wing.
The button plate is provided on its inner face with a shank forming the guide of
the stem being connected with the folding wing. The latter is held in position by
means of its Hat spring bearing either upon the front edge or upon the side of the
stem. The stem is provided with a second flat spring having two tappets the first
of them engaging with a perforation of the shank in case the stem projects from the
shank as much as possible but bears upon the inner edge of the shank respectively
upon the base-plate in case the stem is thrown inwards. In the latter case the
second shoulder is formed by the button proper into the cavity of which the stem
reaches and comes in contact with the bottom of the latter. The second tappet
bears upon the inner edge of the shank or the button-plate in case the stem is in its
utmost projecting position and so the latter is not allowed to be moved further.

COMPLETE SPECIFICATION.
Improvements in Detachable Buttons or Studs.
I, JOHANN HINRICH SOHNHOLTZ, of 9 Bachstrasse Hamburg, in the Empire
of Germany, 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 :-
My present invention relates to detachable buttons or studs in which the fastening
is effected by means of a folding wing pivoted to the shank of the button and
especially that class of such buttons, in which the length of the shank is a
variable one.
The object of the said invention is to afford means for automatically arresting the
longitudinally movable parts of the shank in order to facilitate the shifting of the
folding wing.
In the accompanying drawing,
Figure 1 is a sectional side elevation of my improved fastening device.
Figure 2 is a cross section of the same.
Figures 3 and 4 are two different views showing the folding wing in both its
extreme positions and the stem to which the folding wing is pivoted in its outermost
position.
Figure 5, is a sectional side elevation of the button showing the parts of the
fastening device in the closed position, and
Figure 6, is a cross section of Figure 5.

The latter is held in
The button plate a is provided on its inner face with a
guide of the stem being connected with the folding wing c.
position by means of its flat spring d bearing either upon the front edge, Figures 4
and 5 or upon the side of the stem, Figures 1 and 3. The stem is provided with
a second flat spring e having two tappets el 2 the first of them engaging with a
perforation or cavity a² of the shank in case the stem extends beyond the shank
as much as possible but bears upon the inner edge of the shank or upon the base-
plate in case the stem is thrown inwards. In the latter case the second shoulder is
formed by the button proper f into the cavity f of which the stem reaches and
comes in contact with the bottom of the latter. The second tappet e² bears upon
the inner edge of the shank or the bottom plate when the stem is in its outermost
position so as to prevent the latter from being moved further out.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The hereinbefore described fastening device for detachable buttons and studs
consisting of the shank a' forming the guide of the stem being connected with a
folding wing and provided with a spring operated tappet e' serving to engage with
a projection or cavity a' of the said shank, substantially as and for the purpose set
forth.
