I, ALEXANDER HEINRICH RIETZSCHEL, of Gabelsbergerstrasse, 36 and 37,
Munich, in the Empire of Germany, Optician, do hereby declare the nature of
this invention to be as follows:
The present invention relates to improvements in hand photographic cameras
which may be employed for photographing with films or with plates as desired
without however materially increasing the size and portability of the apparatus

In photographing with films the camera is arranged as follows: The lid being
folded down and the camera drawn out, the film box is adjusted in proper
position on the box. If it is desired to photograph with plates the apparatus
may be placed on a tripod to which end a housing is provided with screw holes,
or the same may be used by hand in the ordinary manner without the tripod.
The roll box is slid off the camera box or casing and in order to preserve the
proper distance of the lens from the plate a frame may be fitted on to the end
of the housing into which either a dull glass plate frame or a double plate frame
may be slid in the known manner.
When the operation has been completed the camera is folded back into a
part of the housing and the lid turned up and fastened by any suitable hook
device.

Improvements in Photographic Cameras.
I, ALEXANDER HEINRICH RIETZSCHEL, of Gabelsbergerstrasse, 36 and 37,"
Munich, in the Empire of Germany, Optician, 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 improvements in photographic cameras
which may be employed for photographing with films or with plates as desired
without however materially increasing the size and portability of the apparatus.
In order to render the specification more easily intelligible reference is had

page_text: to the accompanying drawing in which similar letters of reference denote similar
parts throughout the several views.
Fig. 1 is a plan of the apparatus folded together.
Fig. 2 a front elevation of the apparatus showing the film containing portion
partly drawn out for removal.
Fig. 3a cross section through Fig. 2.
Fig. 4 a plan of the apparatus with the camera drawn out.
Fig. 5 a side elevation of the apparatus with the film box removed.
Fig. 6a plan of a frame to be attached to the apparatus when the film box
is removed and
Figs. 7 and 8 end views of frames to be inserted as hereinafter set forth.
Two end or side chambers a a contain the rolls for the film and between the
two a box is arranged to receive the expansible chamber or camera c. A
second box or casing connects the two roll chambers and the film passes through
this chamber, which is provided with a dark slide (Fig. 3). The camera cis
provided with the ordinary expansible part and the cover f is adapted to fold
down in the ordinary manner and be retained in position by means of a self
adjusting stay bar g. A snap spring a may be employed to retain the roll and
film box in position when photographing with films.
In photographing with films the camera is arranged as shown in Fig. 4. The
lid being folded down and the camera e drawn out, the film box is adjusted in
proper position on the box b. If it is desired to photograph with plates the
apparatus may be placed on a tripod, to which end the housing is provided
with screw holes or the same may be used by hand in the ordinary manner
without the tripod. The roll box a ad is slid off the camera box or casing b,
and, in order to preserve the proper distance of the lens from the plate, the
frame m (Fig. 6) may be fitted on to the end of the housing into which either
a dull glass plate frame n or a double plate frame o (Fig. 7) may be slid in the
known manner.
When the operation has been completed the camera is folded back into the
part of the housing j and the lid turned up and fastened by any suitable hook
device (Fig. 3).
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
-
1. In a photographing apparatus having an expansible camera and box b,
the combination of a roll box a a having casing d with dark slide i, said box
being adapted to fit on to and round the box or housing j by being slid over
the same in the manner and for the purpose substantially as described.
2. In a photographing apparatus, the combination of a camera box having
cover or lilf and camera cand a roll box having roll chambers a a at either
side of the camera box and a film casing. with dark slide to connect said roll
cases and lie along the back of the camera box, said whole roll box being adapted
to slide vertically on the camera box substantially as described.
3. In a camera having expansible camera c and box the combination of the
roll box to slide on said camera box having film roll chambers located as specified
and a frame m to fit the end of the box b when the film box is removed in the
manner and for the purpose substantially as described.
Dated this 21st day of March 1900.
