Improvements in and connected with Pictures.
We ALOYS HANNEN, Manufacturer and AUGUST MICHLER, Manufacturer,
both of 68 Doinstrasse, Cologne on the Rhine in the Province of Rhineland and
Kingdom of Prussia 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 present invention relates to a wall-picture, by means of which, while the
same frame is retained, various pictorial representations can successively be shown
to the looker on.
In Figure 1 the annexed drawing shows the internal arrangement of the
picture in a front-view, in Fig. 2 in an upper-view and in Figure 3 in a side-
view or section to x-x of Fig. 1.
a is the picture-frame, the form, size and make of which may be of any kind;
on a are fastened the glass b as well as the card-board c serving as a border for the
picture.
Behind the two vertical parts of the frame two rollers d d₁ are moveably
attached. These rollers are intended for the reception of a series of pictures e
lying side by side. This series is glued with its narrow edges to one of the rollers
and then is rolled up on the one roller e.g. d, so that on the other roller d₁ being
turned, it can roll itself on the latter and unroll itself off d.
This causes the pictures to pass slowly before the opening in the card-board c,
thereby causing a change of the picture contained therein.
The motion of the pictures, i.e. the turning of the rollers is caused by weights ffi
in the kind of apparatus shown in the drawing. These rollers are fastened to
cords g g, which are wound up on little rollers й k₁ arranged below the rollers d d₁
and run over guide-rollers h h₁.
In order that the necessary tension in the picture that happens to be before the
opening in the card-board may be always obtained, while the series of pictures is
being wound off, it is carried over two guide-rails 11, which always keep the
picture well stretched.
The series of pictures is set in motion by pulling at the one weight or by raising
the other. When the weights are continually drawn or raised, the various
pictures pass by uninterruptedly before the opening in the card-board; of course it
is possible to make any picture stay in the opening for a considerable time, by
letting the weight go at the moment in which the picture completely fills up
the gap.
Instead of using weights as a means of motion handles may also be employed.
These are attached to the axles of the rollers d d₁ projecting below through the
picture-frame; or these axles can be made square at the outer end and a key or
krank be used.
Instead of the rails for stretching the picture, small plate-springs can be used,
which press on the rollers and thus prevent the pictures from rolling up.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
Novel picture, consisting of a frame provided with glass and cut-out cardboard,

page_text: two rollers d d₁ arranged inside the frame and alternately receiving the series of
pictures and revolved by means of a weight or a spring as well as of rails for
keeping the pictures passing behind the opening stretched.
