Improvements in Buttons with Fastening Mechanism.
1, KARL DIETERICH, of Dachauerstrasse No. 82, Munich, in the Empire of Germany,
Mechanician, 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 an improved button with fastening mechanism and has for
its purpose to facilitate the attachment of such buttons to and removal from the cloth
and at the same time to increase their durability.
Referring to the accompanying drawing
Fig, 8 illustrates the improved button when closed.
Figs. 1 to 6, represent details thereof on an enlarged scale respectively in top
view and cross section.
Fig. 7 is a vertical section of the button on an enlarged scale.
Figs. 9 and 9 illustrate the tool for fastening and unfastening the improved button and
Fig. 10 shows on an enlarged scale the manner of opening or closing the same.
Into a mould a with small rim, Figs. 1, 1 is introduced a disc b, Figs. 2,
2b in
order to strengthen the former. A centrally perforated concave spring c, Figs. 3ª, 3b,
is placed with its inner side on said disc, which is subsequently covered by a concave
closing plated Figs. 4 4b, having two apertures and a slit connecting the same.
done, the rim of the mould is bent round so as to lock said parts firmly together,
except that the spring is allowed some little play, Figs. 5* 5..
This
The upper part of the improved button consists of the neck e rigidly connected with
the top plate Fig. 6 and having at the bottom two lateral recesses.
The improved button is fastened to the cloth as follows:
After piercing the cloth with the pointed side f of the tool or key Figs. 9* 9b, the
neck is passed through and placed into one of the apertures of the plate d, which is
then pressed and shifted on a little. The two parts of the button are thus firmly
connected with each other, Fig. 7, the extremity of the neck e pressing the spring c
slightly down, being brought to the centre by shifting, and causing the recessed part
of the neck to lay itself into the slit of the plate d and to catch into the hole of the
spring c. The latter therefore prevents the extremity of the neck from lateral
displacement and a vertical disconnection of the two parts of the button is rendered
impossible by the rims of the slit of the plated having entered into the recesses of the neck e.
Το open
the button, the spring e is depressed by means of the pivot g of the tool, as
shown by Fig. 10, and caused to release the extremity of the neck. Subsequently the
latter is shifted to the side opposite to the tool and thereby leaves with its recesses the
rims of the slit of the plate d. On releasing the tool and the neck e, the two parts of
the button are disconnected by the spring pressing the neck out through the aperture
of the plate d.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is
A button with fastening mechanism consisting of a mould a with or without
stiffening plate b, a spring c with aperture, a closing plate d with two apertures and a
slit, and a recessed neck e, the button being closed by pressing the neck e into the
plate d and displacing it so as to cause it to be held fast by the slit rims of the plate d
and by the spring, while the opening is effected by depressing the spring c by means
of a tool Figs. 9 9, substantially as set forth.
