PROVISIONAL SPECIFICATION.
Improvements in and Connected with Photographic Cameras.
I, PAUL JULIUS GUITON of 1 Boulevard St. Denis, Paris, France, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
With portable photographic apparatus, such as those used by tourists, there is
always a difficulty in the replacing of the sensitive plates after each operation; this
replacing takes some time and is somewhat difficult.
Now the object of my invention is to construct a multiplex sensitized plate carrior
in which the changes of the plates can be quickly and readily effected. For this
purpose I employ a frame divided into any suitable number of compartments in which
the sensitized plates or glasses are lodged. Theso compartments are uncovered in
succession by an endless band furnished with slips of wood. A part of the surface
of this band equivalent to that of one compartment is cut out, and at this place it
carries the dark chamber. The dark chamber follows the movement of the endless
band and is therefore put in communication with each sensitized glass in succession ;
it is separated therefrom by a shutter which is drawn out at the time of the operation.
At one of the sides of the frame I form opposite each compartment a notch, with
which a small rod or stud fixed to the dark chamber engages. The chamber is thus
guided to the proper position at each change, and its stability is ensured during the
operation.
It will be understood that I can double the frame and have two rows of sensitized
plates and cause the dark chamber to turn around the frame; or I can give a
rectilinear movement to the band and have any desired number of compartments; or
the frame can be fitted to a fixed dark chamber, and in this case the frame would
move.

1, PAUL JULIUS GUITON of 1 Boulevard St. Denis, Paris, France, 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:
With portable photographic cameras such as those used by tourists there is always
a difficulty in the replacing of the sensitized plates after each operation; this
replacing takes some time and is somewhat difficult.
Now the object of my invention is to construct a multiplex sensitized plate carrier
in which the changes of the plates can be quickly and readily effected.
Figure 1 of the annexed drawings is a longitudinal section, Figure 2 a transverse
section, and Figure 3 an elevation of an apparatus constructed according to my
invention. a is a frame divided into any suitable number of compartments in which
the sensitized plates or glasses bare lodged. These compartments are uncovered in
succession by an endless band c furnished with slips of wood. A part of the surface
of this band equivalent to that of one compartment is cut out, and at this place it
carries the dark chamber d which is held by the plates ff. The dark chamber follows
the movement of the endless band and is therefore put in communication with each
sensitized glass in succession; it is separated therefrom by a shutter g, which is
drawn out at the time of the operation. At one of the sides of the frame a I form

page_text: opposite each compartment a notch h with which a small rod or stud i fixed to the
dark chamber engages. The chamber is thus guided to the proper position at each
change, and its stability is ensured during the operation.
It will be understood that I can double the frame and have two rows of sensitized
plates, and cause the dark chamber to turn around the frame; or I can give a
rectilinear movement to the hand and have any desired number of compartiments; or
the frame can be fitted to a fixed dark chamber, and in this case the frame would
move.
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 I claim in respect
of photographic cameras is :-
A multiplex sensitized plate carrier constructed substantially as hereinbefore
described for the purpose set forth.
