COMPLETE SPECIFICATION.
A Metallic Fastener for Pasteboard and the like.
I, CARL FRIEDRICH GRAUPNER 10 Kleinrückerswalder St., Annaberg Saxony,
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 :-
The object of the present invention is to construct a fastener, for effecting a
permanent connection between the several parts of articles, for use or ornament,
made of pasteboard and like material, which in case of breakage or damage can be
easily exchanged or replaced.
To fasten together the several parts of articles made from pasteboard it has
hitherto been found necessary to leave strips or projections at the edges of one piece
corresponding with holes punched in the other piece.
Through these holes the strips or projections were passed, bent over, and fixed
either with glue, gum or other adhesive material.
Such a joining or connection is however. unsuitable for a many of such articles,
it is also not substantial and endurable, as the strips or projections formed from the
brittle pasteboard easily break off, or, at all events do not effect a firm connection
of the several parts.
The annexed drawings show the fastener made from any suitable metal, that is
to say :—
Fig. 1, the fastener in several stages of its application ;
Fig. 2, the connection of two pieces of pasteboard by the fasteners;
Fig. 3 and 4, the application of the fastener to an article of use.
In Fig. 1, is represented a fastener of my invention. It is made from a strip of
brass, German silver, or other suitable metal, ornamented in various ways so as to
suit the article to which it is to be applied.
The said strip of metal has two hollow knobs or projections b, impressed
upon it.
When used the strip is passed through the piece of pasteboard, which it is
intended to fasten to another piece, and bent twice at right angles so that the two
knobs or projections come opposite each other.
By the application of a punch to the hollow side of the metal, the knobs are then
brought so close together that the pasteboard between them also takes the shape of
the hollow knobs, thereby fixing the fastener immovably to its place.
The other end of the fastener is then passed through the part which is to be
connected to the first piece, and bent over at a right angle as this has been done
heretofore.
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 :-
:-
A fastener, a, made from a strip of metal for the connection of the several parts
of articles of use, having hollow knobs or projections b, impressed thereon and
which at one end is bent twice at right angles in such a manner that the one
knob b, will press the interplaced pasteboard into the hollow of the other knob b,
the other end of the strip being passed through an opening in the second piece of
FD971

as hereinbefore described and illustrated.
