Improvements in Fastenings for Clothes and the like.
CARL ROBERT VIEHOFER 150 Friedrich Strasse, Berlin Germany Engineer, 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:-
The same is a covered, automatically opening, fastinings for clothes, flexible and
rigid articles and illustrated in
In fig. 1 in section along line a b; fig. 2 in section on line ed; fig. 3 is a plan,
the cover having been removed fig. 4 is a view seen from underneath, fig. 5 shows
the underpart and fig. 6 is the cover A in elevation and section.
As may be seen from figs. 1 and 2 the fastening consists of two parts, first, the
oval cover A serving instead of a button hole and having a hole in the middle and
secondly the piece B, taking the place of the button. United with this, or rather,
formed of the same piece is the strip D, having projection H. Further, connected
to B is the covering plate or protecting plate E having stud G and strip F and
moveable in an upward direction, and carrying pin G ending under projection H.
On plate B is also a hollow cone I having a cylindrical foot lying over the hole in
plate B and provided with a side slit so that projection H may pass through out of the
cylindrical foot.
The fastening operates in the following manner. When plate A is passed over
the cone I, the projection H moves back in the hollow space far enough to allow
of A resting on B whilst pin G, is pressed back in a downward direction. There-
upon H advances again and holds plates A and B together by its elasticity, also keeping
pin G in a strained position. Should it be desired to open the fastening, the pro-
jection H must be drawn so far back-by means of the cord etc. K attached thereto-
until it is even with the edge of the cone and pin G owing to its elasticity-the
restraint beeing removed-snaps plate A upward.
Stud I on plate E has the purpose of preventing the elastic parts from being
pressed too sharply on B whereby their elasticity would soon become weakened.
The manufacture of the fastening is carried out by first stamping a plate of the
form shown in fig. 5. The projection H is then bent round at an angle of 90° and
then the elastic strip D at an angle of 180°, i.e. until projection H projects into the
cone I through the opening in D. Plate E is there upon bent round in the same
manner whereby the use of a lock of corresponding size provides a fastening for all
sorts of articles.
The combination of several separte locks on fastenings in a row forms a method
of fastening clothes. The closing of the separate fastenings is effected by pressure
whilst all may be opened by pulling the cord.
In the method of manufacture herein before described the fastening has been
considered as a whole, but the various parts for instance D, E etc. may each be
considered as forming and then afterwards fitted together.
New and original is the combination of several cords etc. K into and, as in the case
of clothes, where several fastenings are used together. This combination may be
made in such a manner that the cord of the lowest fastenings may be joined to that
of the next above and so on.
This manipulation is repeated as many times as there are fastenings and then the cord
of the uppermost fastening will serve to open all the others:
Further, the separate cords etc. H beginning at the lowest may be led separately
upward and there united with the uppermost cord and formed together into a tassle or
combined in any similar manner.
Lastly an opening arrangement for the fastenings may be made, consisting of the
cords from several groups of fastenings, combine.).

page_text: Having now particularly described and ascertained of my invention and in
what manner the same performed, I declare that what I claim is
1.) A fastening mechanism consisting of the two parts A & B of which the former
is pressed on to the latter and held on to the same so long until the projection H
on the elastic strip D is forced back into the exna I by means of the cord K whereby
the pin G on the elastic strip F of the cover plate E snaps the piece A from out
piece B.
2.) The combination of the separate cords etc. K into one, for the purpose of opening
all the fastenings connected together, at once.
