Improvements in the Method of and Means for Attaching Flat Bodies
to each other.
.
I, GEORG COHN, of Königsplatz. 3A, Breslau, in the German Empire, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the method of and means for attaching together flat
bodies such as two pieces of flat or sheet metal, cards or the like.
In carrying this invention into effect one of the sheets is cut in such a
manner that a flap or flaps can be raised from it. The other sheet is perforated
or has a piece cut out of it, and the flaps of the first piece are passed through
the perforation and are then pressed down or flattened out. The flaps in their
flattened condition occupy an area larger than the area of the holes through which
they are to be passed so that to enable them to go through they have to be
suitably bent. After they have been inserted and flattened down they are of such
a size that they cannot be withdrawn. If the hole through which the flaps are
passed is circular, then the two joined pieces may be rotated around each other.
It is preferred to raise two flaps upon one of the pieces, but if desired one
only, or three or more may be formed. If the hole formed in the other piece is
not circular then rotary motion is not permitted, or is only partially permitted.
One of the pieces to be joined may be provided with an extension to act as a
handle so that rotary motion may be easily imparted to one or both of them.

Improvements in the Method of and Means for Attaching Flat Bodies
to each other.
I, GEORG COHN, of Königsplatz, 3a, Breslau, in the German Empire, Manu-
facturer, 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 the method of and means for attaching together flat
bodies such as two pieces of flat or sheet metal, cards, and the like.
In carrying this invention into effect, one of the sheets is cut in such a
manner that a flap or flaps can be raised from it. The other sheet is perforated
or has a piece cut out of it, and the flap or flaps of the first piece is or are
passed through the perforation and is or are then pressed down or flattened out.

page_text: The flaps, in their flattened condition, occupy a larger area than that of the
opening through which they have been passed, so that they have had to be bent
or curved to get them through, and it follows that after being flattened, they can
only be withdrawn after having been re-bent or re-curved. If the opening
through which the flap or flaps has or have been passed, is circular, then either
of the two joined pieces may be rotated relatively to the other.
It is generally more convenient to raise two flaps on one of the pieces, but
one only, or more than two may be raised. If the hole formed in the one piece
is not circular, the rotary motion of the one piece relatively to the other is
limited.
One of the pieces to be joined may be provided with a handle or extended part
by means of which it may be manipulated.
I will further describe my said invention with reference to the accompanying
drawings, in which:-
Figure 1 shews, in plan, two pieces of sheet metal or the like attached together
according to these improvements; and
Figure 1, perspective views of the two pieces separately.
Figures 2 and 2"; 3 and 3"; and 4, 4, and 4b; illustrate modifications of the
form shewn by Figures 1 and 1".
Figure 5 represents an application of the invention.
Referring to Figures 1 and 1", a b, indicate the two pieces, attached in Figure 1,
and separate in Figure 2. In a, two concentric arcs of a circle are cut, forming
the two flaps ed, which may be raised up, and which are connected with a by
-the integral strip ef. In the other piece b, a circular piece y, is entirely
removed. The diameter of this circular part is smaller than that of-the-circle-to
which the two flaps cd are formed. The two flaps ed are slightly bent and are in
this condition passed through the opening y, after which they are re-flattened as
shewn by Eigure 1. Either piece may now be moved to any angular position
relatively to the other while still remaining-firmly-connected.
In the modifications represented by Figures 2 and 2", and 3 and 3", a single
flap chaving a handle or extension 2, is produced, leaving a somewhat crescent
shaped piece or part a. When the two parts have been connected either part
may be moved in a plane-parallel-to-the-other through any angle, but if the
circle be incomplete as shewn at gl, Figure 3, for example, the relative move-
ment is limited in both directions by the contact of the part el, Figure 3, with
the part of the opening g, Figures 3 and 3". Both the flap c and the hole g,
or either of them may have any other suitable shape.
In the modification represented by Figures 4, 4", and 4, the latter of which
represents a longitudinal vertical section, the hole g is oval, and the flap dis
formed to the segment of a circle.
Figure 5 shews the application of my improved connection to a moving toy
figure representing a girl taking tea. The right arm is attached to the body by
the connection illustrated by Figure 3, and it is moved by manipulating the
handle or extension . The described means for connecting two flat parts may
be otherwise variously applied wherever two such parts or either of them have to
be moved around a centre in both, or one, of two closely parallel planes.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
1 claim is:-
1. Means for connecting two flat paper, sheet metal or the like articles, in such
a manner that either may be angularly moved relatively to the other, which con-
sist of the flap or flaps cd cl cut out of the part a, and an opening cut in the
part b, the flap or flaps having a larger area than the opening and being bent to
pass through and afterwards flattened, substantially as described and as illustrated
by the accompanying drawings.
2. In means for connecting two flat paper, sheet metal or the like articles

page_text: hereinbefore described, the device for limiting the angular motion of one part
relatively to the other, arranged substantially as set forth and as illustrated by
Figures 3 and 3 of the accompanying drawings.
3. In means for connecting two flat paper, sheet metal or the like articles
hereinbefore described, a handle or extension c² upon the part or flap a, by which
the part a may be manipulated, substantially as set forth and as illustrated by
the accompanying drawings.
