An Improved Revoluble Miniature Diorama.
I, JACOB KAUFMANN, of 16, Schillerstrasse, Frankfort-on-the-Main in the
Empire of Germany, Merchant, 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 has for its object an apparatus which is arranged for holding
and showing a large number of photographic views of various objects. These
views are arranged on a considerably reduced scale on suitable mediums, and can
be observed by means of magnifying glasses. It is consequently possible to
arrange a number of pictures in a small case, and in this manner to produce a
miniature diorama.
The invention is shown in the accompanying drawings, in which,
Figure 1 is a front elevation with front of the case removed;
Figure 2, a cross section; and
Figures 3 and 4 similar views of another form of construction.
A revoluble disc b of cardboard, metal or other suitable material is arranged in
a small case a similar to a watch case of nickelled metal or the like. In this disc b
a number of holes are arranged concentrically, in which holes are inserted so
called Stanhope lenses d, that is to say glass bars which are ground in the form of
a lens at one end and at the other are ground flat and on these flat sides carry.
micro-photographs. An opening e of the same size as the lenses is arranged at
one place in the casing. By means of a suitably constructed arrangement f
adapted to revolve the disc, it is possible to bring successively the several views
in front of the opening and into sight.
The device which effects the rotation of the disc may be made in various ways.
It mainly consists of a ratchet wheel having as many teeth as there are lenses and
which can be moved one tooth forward each time by means of a suitable pawl
device. The arrangement by which the mechanism is moved may also be of any
suitable kind and may be attached to the bow or in any other suitable manner,
such, for instance, in the manner of the releasing mechanism used in repeating
watches, see Figures 3 and 4. This consists of a slide, by the lateral adjustment
of which the disc is moved each time so far that a fresh picture comes in front of
the opening. An arrangement may however be adopted by which the mechanism
is moved by means of the knob g carrying the bow of the case, Figures 1 and 2.
Another form of construction is shown in Figures 3 and 4. Here only one
lens d is provided, and is not mounted in the revolving disc but in the front of the
case. The photographic views are arranged on a revoluble transparent disc b and
are moved past the lens with the said disc. The effect is of course the same as in
the form of construction previously mentioned. Of course in each case there is
opposite the peephole another opening for admission of the light necessary for
seeing the views.

page_text: 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:-
1. A revoluble diorama, characterised by the arrangement in a casing (a) of a
revoluble disc (b) carrying lenses (d) provided with miniature photographs, said
disc being adapted to be rotated by suitable devices in such a way as to exhibit
the photographs successively opposite suitable openings in the case substantially
as described.
2. A form of construction of the apparatus herein described characterised by
only one lens being arranged in a suitable opening of the case, whilst the micro-
photographs are arranged on a revoluble transparent disc b and adapted to be
moved past the lens by the said disc substantially as described.
Dated this 31st day of August 1897.
